1 internship background 1. 1 internship purpose graduation internship is an important way to combine theory with practice. Through contact and participation in practical work, we can enrich and expand our knowledge, cultivate our comprehensive application ability and lay the foundation for future work. Through what I saw and heard at the internship site, I sorted out my own knowledge system and built my own system. The specific objectives and tasks are: 1. Understand the structural form, structural characteristics and construction methods of buildings, and understand the wall types, structural layout, detailed structure and structural characteristics of buildings. 3. Understand the types of slabs, beams and columns of buildings, reinforcement methods and their connection structures with walls and beams, and understand the characteristics of floor slab, roof structure and roof structure. 4. Bricklaying method. 5. Summarize what you have learned and leave valuable experience and wealth. 6. The teacher's explanation at the construction site is transformed into his own cognitive understanding and becomes his own thing.

1.2 Practice requires you to be humble to the teacher, be diligent and studious, and make necessary records. During the internship, you should obey the guidance of the instructor and complete the tasks assigned by the instructor or internship unit on time. Pay attention to safety during the internship and wear safety helmet when entering the construction site. Visit and learn the construction technology and construction organization and management methods of each type of work, learn to apply relevant engineering construction specifications and quality inspection and evaluation standards, and learn the treatment methods of technology in construction.

1.3 place and time of practice: Jinan time: 2011April 15 2 internship content 4 and 15 the school organized a group of students to visit and study in Linyi construction site, which provided a platform for us to contact the construction site directly. So that we can better understand the society and our major. We came to Kaiyuan Shangcheng. The construction unit of this project is Kaiyuan Real Estate Co., Ltd., which is undertaken by tianyuan group. This project adopts brick-concrete frame-shear structure, with a construction area of about 4 1.372 square meters. The total cost is about 40 million yuan. Construction dates are June +00, 2065438, June +05, 2065438-March 30, 2065438 +02. 2. 1 Types and requirements of deformation joints: 1 Graduation practice of Qingdao University of Technology. Due to the influence of temperature change, uneven foundation decline and earthquake factors, buildings are prone to deformation or damage, so the house should be divided into several independent parts in advance during design, so that each part can be transformed freely and independently. The reserved joint of this vertically separated building is called deformation joint. Including expansion joints, settlement joints and seismic joints.

2. 1. 1 expansion joint: when the building is affected by temperature, it will expand and contract. The bigger the building, the greater the deformation. When the length of a building exceeds a certain limit, it will crack due to excessive denaturation. In order to avoid this situation, gaps are usually set along the height direction of buildings. The width of expansion joints is generally 20-30MM, and its position and spacing are related to the structural type, materials, construction conditions and local temperature changes of buildings. It is required to disconnect the wall, floor and roof of the building. Because the foundation is buried in the soil, it is less affected by temperature change and does not need to be disconnected.
