While using green building materials, we should always keep the indoor air open and release harmful gases in time during the construction process. At the same time, construction waste should be properly classified to ensure that the health and environment of construction workers will not be affected during the construction process.

Several points of home decoration

Don't look for "decoration guerrillas". Street decoration guerrillas are unreliable. These decoration guerrillas often have no business license, no qualification grade, no office address and no formal construction team, which is purely illegal. It is also that the process practice is not standardized, and where it can cut corners, it will cut corners.

We should put safety first, do not change the building structure at will, effectively arrange indoor space, and make the overall layout balanced and orderly. The size and layout of furniture and furnishings should conform to the user's daily life rules and human dimensions.

Understand the common sense of family decoration consumption before decoration.

To have a psychological price, before the decoration, we must have a preliminary positioning of the decoration level of the room, including the preparation of investment, so that the limited funds can play the greatest role.

Calculated separately, home decoration is divided into two forms: "all-inclusive" and "clear package".

To sign a strict construction contract, before signing the contract, it is necessary to know all kinds of materials (including construction costs) and the manager's reserve price in detail, list the construction contents, and indicate the unit price, brand, grade, specification, quantity and decoration requirements of the main materials.

Considering indoor lighting and ventilation, stained glass and coated glass should be used with caution in smaller rooms.

The use of materials should meet the actual needs of users, and do not be too biased towards certain materials to affect the overall use effect.

Family decoration should put users' personal hobbies and interests in the first place, not blindly follow the trend, and the functionality of the room should also meet the needs of life and work.

Master the payment skills, and don't pay in full before the project is completed or accepted.

Acceptance is an important means to protect owners' rights and interests. At present, the project acceptance can be carried out in accordance with the Code for Quality Acceptance of Home Decoration Projects in Beijing, which has been uniformly implemented in Beijing, or professionals can be invited to carry out the project acceptance.

Sign the project warranty agreement. After the project is completed, it will be delivered as scheduled. Formal decoration companies should sign a project warranty agreement with customers for at least one year.

Concept, purpose, task and classification of architectural decoration design

(A) the concept of architectural decoration design

The so-called architectural decoration design is to use modern material means, scientific and technological means and artistic means to create an indoor and outdoor environment design with reasonable function, comfort and beauty, rich personality, satisfying people's physiological and psychological needs, making users feel happy and convenient for study, work, life and rest.

In the design, the main basis for grasping the design object as a whole is:

(1) nature of use (2) environment (3) corresponding standards

(two) the purpose and task of architectural decoration design:

The purpose is to create a beautiful indoor and outdoor environment for people's work, study, life and rest, and meet people's material and spiritual needs.

The task is to comprehensively use modern material means, scientific and technological means and artistic means, fully consider the influence of natural environment, make use of favorable conditions and eliminate unfavorable factors, organically combine the function of architectural decoration with artistic beauty, and make this environment comfortable, artistic and personalized.

(3) Classification of architectural decoration design

Can be divided into outdoor and indoor two categories; Outdoor decoration can be divided into external decoration design and building external environment decoration design; According to different functions, the interior can be divided into two parts: interior decoration of residential buildings and interior decoration design of public buildings.

Need to know about safe home decoration

Home improvement safety starts with electricity, and electrical lines should be laid with concealed pipes. There should be no knots and kinks in the pipes, and bare wires are not allowed in the ceiling. It is forbidden to directly bury the wires in the plastering layer.

Don't forget the waterway safety. When the pipeline is installed, it should be horizontal and vertical, and it should be laid firmly. Waterproofing between bathroom and bathroom is also a key link in decoration.

That is, family decoration should ensure the safety of the building structure, and it is strictly forbidden to dismantle, modify or damage the main load-bearing structure.

Do not arbitrarily increase the floor load, fill or thicken the balcony floor, etc.

Do not change pipelines, such as wires, gas, heating, water pipes.

Do not change the use of the house without authorization.

Don't dig the wall and cut the steel bar because of laying the pipeline.

Use environmentally friendly and healthy materials.

Improve the living environment scientifically

People spend most of their lives at home. In order to get a good rest environment and make people have enough energy to devote themselves to study and work, we must fully ensure a comfortable indoor environment. Including room ventilation, lighting and sunshine, shading and dust prevention, warmth and temperature regulation, noise prevention and sound insulation.

Ventilation protects the body and mind.

Every room in the house needs ventilation in warm or hot seasons and in cold or humid seasons, which can not only increase people's comfort and pleasure, but also reduce diseases.

The United Nations World Health Organization has analyzed the incidence of cancer in 38 countries in recent 20 years. The results showed that the incidence of lung cancer increased significantly, especially among women. The reason is that many medical experts believe that more than 80% of cancers are caused by family living environment factors. At present, the main factors causing lung cancer in family rooms are as follows:

First, smoke a lot indoors.

Smoking at home is harmful to the whole family. According to the measurement, the harm of passive smokers accounts for about 76% of smokers. Cigarettes contain a variety of carcinogens, including carcinogens, carcinogens and synergistic carcinogens. According to statistics, every 100 cubic meter of air contains 2.82- 14.4 mg of carcinogen benzene, which is extremely harmful. Therefore, smoking heavily at home is the main reason that affects the family living environment and causes lung cancer.

Second, poor ventilation and smoke exhaust conditions in the kitchen.

At present, many families use coal, gas or liquefied petroleum gas as fuel, and the concentration of harmful substances such as sulfur dioxide and carbon monoxide in the kitchen is very high. In winter, in an unventilated kitchen, the content of carbon monoxide is determined, and its concentration can reach the edge of poisoning. Other fuels, such as kerosene, diesel oil and gasoline, will also produce air pollutants when burning, especially diesel oil, and its black smoke is a strong carcinogen. In addition, many people like to burn oil to smoke when cooking. This cooking method is very unscientific, which not only destroys a lot of vitamins in some vegetables at high temperature, but also produces a lot of oil mist condensate when vegetable oil exceeds 270℃, which can cause cell chromosome damage and is carcinogenic. Many housewives have been threatened by oil mist for a long time, which has become an important reason for the rapid increase of female lung cancer incidence. Therefore, it is also very dangerous for lung cancer to cook in a kitchen with poor ventilation and smoke exhaust or to study and rest in a room (bedroom, living room, living room and study room) that communicates with the kitchen. Therefore, a range hood or exhaust fan should be used to improve the ventilation and smoke exhaust in the kitchen. Meanwhile, the kitchen should be separated from other rooms.

Third, the smell of the room.

Such as paint smell, cigarette smell, carbonic acid smell, toilet smell, flower fat smell, mildew smell and so on. It is also a factor that causes diseases.

The following problems should be paid attention to in the ventilation, air exchange, smoke exhaust and odor removal of the living room:

1. Due to the different functions of the living room, the requirements for ventilation are also different. For example, bedrooms, living rooms, living rooms and study rooms are mainly ventilated in summer and mainly ventilated in winter; The kitchen mainly eliminates lampblack and oil mist; The bathroom is mainly ventilated to remove odor.

2. According to the use function of the room, natural ventilation and ventilation should be considered from the perspective of hygiene and safety. In summer, beds should not be arranged where water flows. If necessary, it must be arranged in this position, and the angle of doors and windows must be adjusted before going to bed, so that the human body is not affected by the direct airflow. Beds, combined cabinets, wardrobes, bookcases and other furniture are arranged in the whirlpool area to avoid direct access, and the air flow area is used as a place where people often move. In winter, in order to reduce the spread of the virus, the room should be properly ventilated; Rooms and kitchens equipped with stoves must be equipped with ventilation and smoke exhaust facilities to prevent gas poisoning, fire and smoke pollution.

3. Indoor ventilation is mainly carried out through the reasonable opening of doors, windows and holes. Different opening conditions will produce different air flow routes. According to these airflow routes, rooms can be designed and arranged reasonably, and furniture and home facilities can be arranged to form a good sleeping area, learning area, meeting area, rest area and dining area.

4. Tall furniture and other household facilities should not be placed on the main road of ventilation, so as not to affect ventilation and indoor temperature regulation.

Daylighting and sunshine enhance the sense of beauty and comfort.

All kinds of indoor activity areas need a certain brightness. In addition to indoor lighting, the simplest and most convenient methods are natural lighting and sunshine, which can provide people with good lighting conditions, obtain the best visual effects, make the indoor environment have a certain atmosphere and artistic conception, and enhance the aesthetic feeling and comfort of the indoor environment.

The lighting and sunshine conditions of the living room generally vary with the orientation, floor and shading of the room, and also depend on the position and size of the windows and external doors (connected to the balcony) of the living room. When designing and arranging home facilities indoors, we should consider:

1. The living room, reception room, study room or study place should be located in a room with good lighting and sunshine conditions, while the bedroom has slightly lower requirements for lighting and sunshine.

2. Don't put tall furniture and household facilities near doors and windows to avoid blocking the light.

3. In the living room and bedroom, the area where people often move should be arranged near the window and the outer door, while the bed should be placed away from the window and the outer door.

4. When placing furniture such as writing desks and typing tables, make sure that the light enters the left side according to the incident direction of natural light, so as not to block the light and affect the eyesight.

5. Furniture, arts and crafts furnishings, paintings and pictures should not be exposed to direct sunlight to avoid fading and deformation.

6. Furniture with large mirrors and glass should not directly face the direction in which the main light enters, so as to avoid strong reflection and affect people's daily activities.

Cool, dust-proof, keep privacy.

When decorating a room, it is often necessary to set up shelters to shade the sun, prevent dust and cover the scenery, and maintain indoor privacy. Curtains, door curtains and sunshade facilities are commonly used.

1. Installing screen doors and screens can play a certain role in shading and dust prevention.

2. Use thick opaque fabric to make curtains and glass door curtains. When shading is needed during the day, a layer of light curtain, such as yarn, silk or net buckle, can be added between the curtain and the window to maintain sufficient brightness in the room.

3. Install sunshade facilities to prevent direct sunlight from entering the room in summer, especially the houses in the east, west, east and west of hot areas. Commonly used sunshade facilities include sunshade bracket, sunshade cover, indoor or outdoor sunshade bamboo curtain, sunshade venetian blinds, etc.

4. Although the shelter of the living room can shelter the sun and prevent dust, the radiant heat hitting the shelter will also be directly dispersed indoors. Therefore, ventilation should be considered when adding shelter, so that the airflow entering through the window will not be blocked, and the radiant heat generated by shading can be discharged.

A warm and temperature-regulated room is warmer.

In a room without air conditioning, the temperature, humidity and wind speed are different everywhere, so the measures of keeping warm and adjusting temperature should be considered when indoor layout.

Construction preparation work

What procedures should I go through before construction?

According to the Ministry of construction "family room decoration management pilot scheme":

Before the house owner and user decorate the house, they should register with the grass-roots management unit of the house and go to the urban management department of the local street office for examination and approval. Where the main structure is removed and the load is obviously handled, the housing management personnel and decoration households must go to the housing appraisal department for acceptance.

What are the necessary procedures to be provided to the property management department before construction?

Provide the following procedures to the property management department:

Decoration application, construction drawings and project contents;
