I was born on1979165438+1October 28th. I graduated from Bengbu Staff University in Anhui Province in July 2002 with a university degree, and was assessed as an assistant engineer in July 2008. I have been engaged in project construction management since graduation. During this period, I worked hard to learn professional technical knowledge and devoted myself to scientific and technological innovation and progress in the process of technical management on the construction site. I worked as a builder in Tang Hong Jiayuan No.1 staff residential building and Minshan World Building Phase II project. During the years of training in the front line of construction, the professional knowledge I learned in school quickly turned into business ability. As the technical and quality backbone of the company, under the direct leadership of the company manager and chief engineer, I am meticulous in technical management. After several years of hard work, I have acquired certain construction technical ability and experience. Since August 2008, I have worked as a project builder in Hefei Doors and Windows Co., Ltd. ..
Over the years, in the process of contributing to the development of on-site construction, my professional and technical ability has also been enriched and improved. In a word, I have done some useful work, but there are still many problems to be improved. My professional and technical work is summarized as follows:
First, enhance quality awareness and create architectural products.
In March, 2008, he worked as a project builder in the second phase project of North Zone of University Science Park undertaken by Mianyang Fuxiang Construction and Development Co., Ltd. The project quality is the life of the construction enterprise. In order to obtain good project quality, technical managers are required to have a good sense of excellence. As the project builder of the project, I will take the lead in establishing and perfecting the project first.
Ministry of technology and quality management rules and regulations. According to the project construction method, the project quality objectives are decomposed into various professional and technical posts, and then the construction is organized according to the requirements of technical posts. A series of management systems conducive to ensuring the project quality have been established successively, such as technical review system, project quality inspection system, hidden acceptance system, quality common fault control measures, semi-finished products protection measures and so on. According to the characteristics of large amount of excavation and concrete pouring in this project, the formwork support adopts the tool-type quick release system, and the glued bamboo formwork with film covering is used together to ensure that the gap of bamboo formwork is not more than 1mm and the surface flatness is not more than 2mm, which not only saves the cement consumption, but also completely eliminates the quality hidden danger of ceiling plastering, and realizes the double harvest of economic and social benefits. The surfaces of the tiles on the interior and exterior walls are smooth and clean, with the same color, dense joint filling, straightness and uniform width, and the details of the waterproof layer on the roof are carefully handled, consistent and beautiful. The surfaces of doors and windows should be clean, free from scratches and bumps, and the surface of wall paint should be smooth and even, with uniform thickness and no air holes. Straight line. In the process of construction, the construction shall be carried out in strict accordance with the design and construction drawings and the requirements of national specifications, procedures and general atlas, and various sub-projects shall be completed seriously. Achieved the quality goal of "high standard and high quality". Through the direct participation and control of the technical work of the project, the quality, progress and benefit of the project have received good results.
Two, study hard business technology, do a good job.
I've been doing well since I started working in Hefei Doors and Windows Co., Ltd. in August 2008. Under the tight time and heavy task of this project, I voluntarily gave up my personal rest time and worked overtime without complaint, which fully reflected the due role of a young professional and technical personnel.
In my work as a project builder, I apply my professional knowledge to work practice, from technical guidance and quality inspection and acceptance of the construction site to verification of technical data.
Question 2: How long will it take to dry the ground poured with cement mortar in such a day Abstract: The hollowing and cracking of cement mortar ground is a common quality problem caused by many factors, and it is also an old quality problem. From the very beginning, the name of the common disease of treatment quality appeared and lasted for many years. It is a common quality problem, which not only affects the appearance, but also affects the use function, which is harmful. It exists in the south of China, but it is more prominent in the north, and it is listed as the focus of the treatment of common engineering quality problems in the north. Therefore, it is necessary to prevent and control this large-scale and harmful quality common fault. Based on many years of construction experience, I talk about how to prevent and deal with the common quality defects such as hollowing and cracks in cement mortar surface of building ground during construction. Labels: prevention, cracks, cement,
A, the reason of the cement mortar ground surface empty drum crack 1. Cause analysis of empty drum: (1) The surface of the base course is not cleaned cleanly, and there are rubbish, dust or pollutants, which affects the firm bonding between the surface course and the base course. ⑵ When cement mortar is laid, the surface of the base is too dry, not wet or not wet enough. Therefore, after the cement mortar is laid, the moisture in the cement mortar is quickly absorbed by the base, which leads to the rapid dehydration of the mortar, which makes the hydration of cement particles not fully separated, reduces the surface strength and affects the bonding with the base. (3) When cement mortar is laid, the base is too wet and there is water accumulation, especially the water cement ratio of cement mortar with water accumulation at the base increases, which leads to poor bonding with the base. The surface layer of the upper surface of the pipeline is too thin, which will also cause the surface layer to crack and empty. (4) The brick layer at the entrance is too high or the water is not wet enough, which makes the cement mortar on the surface too thin and loses water too fast, resulting in cracks and empty drums. 5] Before laying the cement mortar on the surface, the process of brushing the cement mortar combined layer was not arranged, and some methods were used to sprinkle cement powder after pouring water, resulting in uneven dusting, uneven sweeping or missing sweeping. At the same time, the consistency of cement slurry is not easy to control, and it is thin and dry, which affects the bonding effect. In addition, the process of brushing cement slurry does not cooperate well with the process of laying surface layer. After brushing the slurry, slowly lay the surface layer. Later, some slurry dried up, which not only failed to bond, but also played an isolation role, and it was inevitable that the surface layer would be empty in the future. 2. Cause analysis of cracks: (1) Cement with poor stability or hot cement just out of the kiln is used in ground cement mortar. Cement and hot cement with unqualified stability, because they contain too much free calcium oxide, magnesium oxide and sulfate, have a very slow curing speed in water. When cement has strength, it can continue to solidify in it, causing volume expansion. If there is too much sulfate, the volume will expand violently, because calcium sulphoaluminate will be produced during hardening. So it will cause surface cracking. When different types and grades of cement are mixed, cracks will occur on the surface layer because of the different setting and hardening time and volume shrinkage of cement. If the particle size of sand is too fine, it will cause the mixture to bleed, or the silt content is too large, and the clay will be adsorbed on the sand, forming a film wrapped with sand particles, weakening the bonding force between sand and cement, reducing the strength of mortar, and even causing surface cracking, even sanding and hollowing. 2 cement mortar water cement ratio is too large, mortar consistency is large or uneven mixing, resulting in mortar segregation, leaving many tiny holes in the mortar, reducing the tensile strength, affecting the bonding strength between mortar and base, and also causing ground cracks. (3) The surface layer is not maintained in time or in place, which increases the shrinkage of cement and causes shrinkage cracks. Because the thickness of the building ground surface is generally thin, if the early maintenance is neglected, especially in the hot, dry and windy season, the cement mortar surface is often prone to shrinkage cracks due to the rapid evaporation of surface moisture. (4) The backfill foundation soil of the bottom ground is of poor quality, or not compacted, or there are frozen blocks or ice cubes in the backfill foundation soil. The temperature rises, the frozen soil melts, and the backfill foundation soil sinks, resulting in hollowing and cracks on the ground. If the floor base is not cleaned, it will isolate the base from the surface, reduce the adhesion between mortar and base, and also cause hollowing and cracks. 5] uneven surface shrinkage. The upper surface of precast floor leveling layer or cast-in-place concrete floor is uneven, resulting in uneven thickness and shrinkage of the ground; Or when the surface layer is calendered, the cement is dry, but it is spread unevenly, resulting in uneven shrinkage of the surface layer and easy to cause irregular cracks in the surface layer. (6) The influence of temperature. On the building floor with a large area, the necessary longitudinal and transverse expansion joints are not set according to the specified requirements. Because there are no longitudinal and transverse expansion joints, there will be large expansion or contraction deformation due to temperature changes, which will cause more irregular cracks on the ground. (7) Unintentional use of additives ... >>
Question 3: When did China begin to have cement? [Exploring the Origin of Ergonomics from Ancient Furniture —— Huang Lihua (School of Art and Design, Nanchang University, 330027) Abstract: At present, it is generally believed that ergonomics was first proposed by Taylor. In fact, as early as ancient times, many products made by human beings reflected the idea of modern ergonomics. This paper analyzes the application of ergonomics in ancient furniture design in detail. It can be seen that ergonomics should have originated in ancient times and developed continuously with the passage of time, which laid the foundation for the systematic proposal of modern ergonomics. Keywords: ergonomics; Origin; Ancient furniture; 1 preface ergonomics is a technical science developed in the late 1940s. The word "ergonomics" was put forward by the Polish professor Yastlebowski in 1857. It comes from Greek. [4] At the beginning of the 20th century, Taylor in Britain designed a set of methods to study workers' operation. This paper studies how to operate labor-saving and efficiently, and formulates the corresponding operating system, called Taylor system, which is the originator of ergonomics. In modern times, ergonomics has become an important factor that designers consciously consider in the design process. Although ergonomics was systematically put forward as a science more than 100 years ago, it is generally believed that it is the origin of ergonomics. In fact, as early as thousands of years ago, man-made articles such as furniture and labor tools have already reflected the application of ergonomics. Online design. China 2 explores the origin of ergonomics from ancient furniture: 2. 1 Ergonomics originated from ancient design online. China people are imaginative, fickle, emotional, sensitive and fragile animals. Therefore, I hope that the artificial environment of life can make people feel comfortable and full of warmth. Design can help people realize their dreams. [3] The design of primitive society, like all human inventions, always aims at changing the world and facilitating life. Every object, every creative process, is inadvertently exploring the roots of human beings. When people create things, they also spontaneously pursue the comfort and safety of products and consider different requirements of people. According to the definition of International Ergonomics Association, ergonomics studies various factors such as anatomy, physiology and psychology in a certain working environment. Study the interaction between man-machine and environment; A subject that studies how to agree to consider work efficiency, people's health, safety and comfort at work, family life and holidays. The contents of modern ergonomics, such as anthropometry, physiological anatomy and psychology, are also reflected in ancient artifacts. The purpose of learning ergonomics is to make people feel efficient, comfortable, safe and healthy when using products. Taking the origin and development of ancient furniture as an example, it shows that the origin of ergonomics began long before Taylor system appeared. 2.2 Application of Ergonomics in Ancient Furniture Design: (1) Embodiment of Anthropology in Ancient Furniture: Design Online. Anthropology is an ancient and emerging science in China. As early as the first century BC, the Roman architect Vitruvi had made a comprehensive discussion on human body dimensions from the perspective of architecture. He found from the relationship between various parts of the human body that the human body is basically centered on the navel. Anthropology is a science that determines the difference of human body size between individuals by measuring the sizes of various parts of the human body. The measured size can be used as a dimension reference for product design to meet people's needs. Although ancient furniture design did not use anthropometry as scientifically and consciously as modern furniture design, some aspects can still be regarded as the application of anthropometry. The household custom in the Warring States period was "sitting on the floor", that is, "sitting on the floor". When sitting on the floor, your knees are on the ground, your hips are on your heels, and your upper body is straight to show solemnity. Therefore, people's sight, height and decorative surface of appliances all determine that lacquerware, lacquered furniture and other furniture are low-type furniture. The ratio of paint box to paint is more scientific and reasonable. For example, the height of the case is mostly between 10 cm and 20 cm. The height of lacquer is generally between 30 cm and 40 cm, which is suitable for people to live in seclusion. [1] The functional design feature of lacquer furniture in Mawangdui Han Tomb is to design it reasonably according to people's living habits at that time. For example, activity 3 is only 16 cm tall, which is suitable for "seclusion". In fact, the size is calculated and designed. The food box has only a short foot with a height of 2 cm, which is convenient for people to send food on a tray and place it conveniently. There is also a 2.3 cm high water retaining line around the case surface to prevent the soup from overflowing. Product size and functional design > >
Question 4: Model essay summary of project feasibility study report There are two commonly used analytical research methods: one is systematic thinking analysis. That is, take the proposed project as a system, analyze all kinds of complex factors involved, and study their relationship and development. If necessary, a mathematical model should be established for calculation and analysis. The second is comparative analysis. Usually, horizontal ratio and vertical ratio are used to analyze the whole or part of the proposed project or even a specific detail. Generally, a variety of possible projects or schemes should be compared and analyzed, and finally optimized. Different types of feasibility study reports have their own characteristics due to different research objects, contents and methods, but the structural elements are basically the same, generally including title, preface, text, signature and annex. The title of the feasibility study report should be written accurately and concisely, mainly in the following two ways. (1) complete formula. Generally, it is composed of the name of the proposed project unit, project name and language type (3 elements), such as the feasibility study report of introducing terrazzo production line into XX new building materials factory. (2) ellipsis. Omit the name of the proposed project unit in the complete formula, such as the feasibility study report of building a large cement plant; Omit the unit name and project name of the proposed project in the complete formula, and only write the language type, such as feasibility study report. The text is the main part of the feasibility study report, which is a concrete analysis and demonstration of the necessity, possibility and technical and economic indicators of the declared project, and finally draws a conclusion on whether it is feasible. It is required to adopt a comprehensive and systematic analysis method, take economic benefits as the core, and demonstrate the feasibility of the proposed project with a large number of data around various factors affecting the project. The text includes five parts: introduction, supply and demand forecast, technical demonstration, economic analysis and conclusion. (1) Introduction. Put forward the basis, purpose and conclusion of the feasibility study project. (2) Supply and demand forecast. Mainly write about the supply and demand situation and development trend of domestic and foreign markets. When studying and writing the supply and demand forecast, we should use scientific methods and conclusive data to make the forecast accurate and credible. (3) Technical demonstration. Mainly use information and data to demonstrate the following aspects: the supply of energy and raw materials; Site conditions and traffic conditions; Technology, equipment and environmental protection; Production organization and personnel training; And make a feasible or infeasible conclusion. (4) Economic analysis. Mainly includes: investment estimation, income estimation and investment recovery estimation. Investment estimation, that is, the estimation of all the funds needed for the project, is divided into two parts: fixed assets investment and working capital investment; Income estimation, that is, estimating cost, selling price, sales volume, profit, etc. ; The estimation of return on investment mainly analyzes the level of return on investment and the length of return period. In economic analysis, it is necessary to accurately estimate the total funds needed for the project, as well as the specific proportion of funds needed for each part of the project implementation and different periods. It is necessary to correctly estimate fixed assets and liquidity. It is necessary to analyze the source of funds, financing methods and repayment methods of the project in a targeted manner. (5) conclusion. It is a comprehensive evaluation of the project on the basis of supply and demand forecast, technical demonstration and economic analysis. There are three kinds of evaluation conclusions: infeasible conclusion, feasible conclusion and compensatory conclusion. The conclusion should not be ambiguous or ambiguous. In order to meet the needs of conclusions, it is often necessary to add some attachments, mainly including various demonstration materials, experimental data, investigation data, calculation charts, drawings and so on. Those that can't be written in the text to enhance the persuasiveness of the feasibility study report.

Abstract: Material is an integral part of the main building, which runs through the whole process of engineering construction, occupies an important position in the construction business activities and has a great influence on the engineering cost. It is an effective measure to control the material management cost and financial cost to reasonably determine the material entry time and purchase quantity. This is the fundamental way to reduce the project cost; It is the main method to improve the efficiency of the use of construction funds.
Keywords: material cost; Bulk purchasing; Management; profit
Materials are the basic premise of all production and business activities and the material conditions of engineering construction. Without materials, no project can be built. Correctly handling the matching relationship between material bulk purchase and project cost is an important problem to be solved urgently in the construction industry.
First, strengthening the accounting and management of building materials has important practical significance.
Materials refer to all kinds of raw materials, main materials, auxiliary materials, outsourced semi-finished products (outsourced parts), repair spare parts, packaging materials, fuels, etc. Changing the shape or nature due to processing in production and business activities. Material account ranks in the front of assets according to liquidity, and its importance can only be seen from its order in the balance sheet. It is not only a current asset, but also an inventory, and it has two conditions at the same time: first, the economic value contained in the material can flow with the changes of production and business activities, and it will bring changes in the cash flow of enterprises; Second, the cost of materials can be measured reliably, and with the progress of production and business activities, changing its own form and value will affect the economic interests of enterprises to a certain extent, and will inevitably affect the final profit of enterprises.
Building materials are the entities that form architectural achievements; It is the main body of project cost; It is the main force to form building products; As an important part of assets, it is highly liquid and can be realized at any time. If accounting and management are not correct, it will not only reduce the efficiency of fund use, but also increase the deviation between accounting records and market prices, leading to errors and distortions in accounting information. The backlog of materials will not only increase the occupation of funds, but also lead to the loss and damage of materials, and will be "retired" because of the emergence of new products. Therefore, strengthening the accounting and management of materials is of great economic value and practical significance to both construction enterprises and construction units.
Second, materials should be purchased and managed according to different varieties.
There are many kinds of materials, different access channels, and different departments have different management and accounting methods. The daily accounting of materials can be calculated according to actual cost or recorded according to historical cost. As the material price of the construction industry, it is generally calculated by stages according to the actual procurement cost under the specific guidance of the Information Price of Building Materials published by the local construction management department on schedule. The actual cost method is used to send and receive materials and record books.
With the continuous transformation of high-tech achievements in the construction industry and the continuous innovation of new materials, more and more old materials are backward because of monotonous functions, and their use is restricted because they do not meet the requirements of the new specifications; Due to the continuous development of construction methods to mechanization and industrialization, the previous raw materials have entered the market and become semi-finished products procurement now; From the original on-site workshop to modern factory operation. This not only brings new problems to material procurement, but also poses new challenges to the cost accounting department. Is it to purchase raw materials for on-site processing or to purchase semi-finished products for direct installation? In what way can procurement reduce the project cost? What kind of scheme can be more conducive to construction? This requires management accountants to analyze and compare the costs of various schemes in detail before choosing the best scheme.
Third, the basic methods of classified management of building materials
1. Formulate and calculate quotas and manage indicative quotas. In the process of construction, we should conscientiously implement the quota management of various materials consumption. First of all, the formulation of consumption quota should have an objective and fair attitude and scientific basis, and must not be fabricated. Secondly, the formulation of consumption quota should be serious and authoritative, and professional and technical personnel with rich practical experience should be organized to make careful analysis and careful calculation, and personal intentions or hints should not be used as technical basis.

Question 7: What are the accounting entries for buying cement in real estate? Buy cement: development cost, infrastructure loan: bank deposit. Are you a development enterprise? Do you build your own project or outsource it?
Question 8: How to write an argumentative essay is an article with argument as the main expression, which consists of three inseparable elements: argument, argument and argument. Argument is the author's point of view (viewpoint, opinion, opinion, etc.), argument is the material (evidence) to prove the point of view, and argument is the process of using materials to prove the point of view. These three elements are the three elements of argumentative writing.
These three elements are essential for argumentative writing, but argumentative writing is by no means a simple superposition of these three elements. For example, writing an argumentative essay is a bit like doing geometric proof problems in mathematics. Argumentation is a conclusion that needs to be proved. Argumentation is some known conditions and mathematical formulas. Argumentation is a process of proving geometric problems by using known conditions and formulas. The demonstration process is the most skillful, which can reflect your writing level and is the key to the success or failure of your composition.
Of course, the establishment and choice of arguments are also very important. If the viewpoint is incorrect, or no evidence can be found to prove it, the result will be fatal. Putting forward one's own opinions is also a series of strong evidence, but the lack of scientific and meticulous argumentation process will also lead to failure.
Many students who are new to argumentative writing write "opinions+arguments+conclusions", or put forward opinions at the beginning, then write one or two stories and finally draw a conclusion. It can be said that this is not an argumentative paper at all. Simply listing evidence is not an argumentative paper, just like piling steel, sand and cement together is not a building. Telling stories instead of discussing arguments is an ambiguous stylistic trend and a taboo in argumentative writing.
The most obvious feature of argumentative writing is that argumentation is the main way of expression, without narration, description and lyricism. What it wants is scientific, rigorous, accurate and objective argumentation, which shows rationality. Placing facts and reasoning are common in argumentative writing. As evidence, the facts and materials cited in this paper should be summarized and concise, without lengthy and vivid details, as long as the summary is simple and clear. Some argumentative essays can be written in satire, laughing and cursing, but we should also pay attention to the degree, convince people by reasoning, and convince those who are satirized and scolded. If you curse the street blindly, it is illogical and readers will not recognize it.
Argumentative writing inspires and convinces people with the brilliance of reason, which is essentially different from lyric prose, narrative and other literary genres. Argumentative writing should pay special attention to the logical rigor of the argumentation process, and there should be no loopholes, generalizations and exaggerations. Once you find a loophole, fix it in time, otherwise it will affect the appeal and persuasiveness of the article, and even lead others to seize your loophole and refute it.
Let's talk about the writing steps or main structure of an argumentative essay first. The main content of argumentative writing is to ask questions, analyze problems and solve problems. Asking questions is to put forward your own views; To analyze a problem is to expound one's own views and opinions. Why do you ask such a question? There must be an excellent reason. Finally, we should put forward the necessary methods to solve the problem.
