(2) The reinforcement can be connected on the premise of following the requirements of the design drawing; Then the fabrication process of positioning steel plate can be started.
From the actual situation, both the effect and the material performance, the comprehensive ability is stronger.
The shear wall structure is mainly composed of two parts: plate members and prefabricated walls.
This paper studies the building system and construction technology of industrialized assembled residential buildings, aiming at promoting the industrialization of housing in China and providing reference for relevant industry.
This type of structure has the characteristics of simple operation, low construction cost and high construction efficiency.
According to the characteristics of the project, the standard construction process is formulated as shown in Figure 1.
Among them, the frame-type fabricated structure mainly consists of prefabricated beam members, slab members and infilled walls, and the structures are connected by pouring concrete.
3.1.2 Reserved reinforcement construction of transfer floor The third floor of the third and fourth floors is the transfer floor, and the first floor of the fifth floor is the transfer floor.
From the perspective of effect, partial assembly is superior to the full assembly process in terms of safety and seismic resistance.
This structure has the advantages of separating different types of houses, and is widely used in high-rise buildings at this stage.
The number of underground floors on the fifth floor is 1, the number of floors above the ground is 4, and the overall building height is 17.85m.
It is usually used in the construction of office buildings, residential buildings and commercial buildings.
In practical applications, lightweight materials are flexible and will not prolong the construction period, which is conducive to control the construction time, Now, it has been widely used in the construction of residential integrated assembly structure.
The number of underground floors on the third and fourth floors is 1, the number of floors above the ground is 18, and the overall building height is 57.16m.
1.2 Classification of assembly degree In the construction of integrated assembly frame structure of industrialized housing at this stage, according to the difference of assembly structure system, the assembly degree can be divided into two types: full assembly and partial assembly.
After the installation of the platform formwork and the binding of the floor reinforcement, the construction tools shall be used to measure and control the positioning line of the reserved reinforcement according to the reserved control points on the floor.
The biggest characteristics of lightweight structural materials are small quality and simple processing.
Housing industrialization has become an inevitable trend of the development of the construction industry, and also one of the manifestations of the modernization of China’s construction industry.
The project includes supporting service rooms and underground garages on the third, fourth and fifth floors.
The frame-shear wall structure combines the advantages of the above two structures, and has extremely strong flexibility and excellent seismic performance.
Most lightweight structural materials, such as glass fiber and wood, can be used in the construction of the system.
The latter comes from a wide range of materials.
The former is mostly used in compound buildings, but the system has the defects of long time consuming and complicated construction procedures.
Most of them are used in small-scale design of residential buildings, such as grid structures.
The integrated shear wall structure is adopted.
1.3 Analysis of the construction materials of the integrated prefabricated frame structure of industrialized residential buildings In the construction materials of the prefabricated frame structure at the present stage, due to the differences in the characteristics and functions of each material, it can be divided into two categories according to the structural system, one is the heavy structural system, the other is the light structural system.
The third and fourth floors are apartment buildings, The fifth floor is the service supporting room.
It is necessary to ensure that the distance between the positioning steel plate holes (reinforcement holes) is less than 4mm, and the hole and the control line must be less than 6mm.
.
Project description: The building area of a residential project is 119724.35m2.
All construction components of the full assembly process shall be designed and completed by professional manufacturers and installed by professional personnel.
According to previous construction experience, the following measures can be taken: (1) survey and setting out.
The design of prefabricated frame structure is consistent with the development direction of the construction industry at the present stage, but according to the development situation, because the construction industry in China is greatly affected by traditional ideas and models, a lot of manpower is still needed in the construction stage, especially the overall level of assembly production and the speed of industrialization promotion need to be improved.
Compared with the general construction strategy, residential industrialization can accelerate the construction speed and improve the construction quality to a certain extent, and can also ensure that buildings have environmental protection performance and strong functionality, which is the development goal of China’s construction industry at this stage.
Generally speaking, because the hoisting accuracy of the first floor prefabricated components will have a direct impact on the positioning of the transfer floor reinforcement to a certain extent, the sequence of each link of the workflow is closely related to the quality and accuracy of the hoisting construction.

Therefore, it is very necessary to study the construction technology of integrated prefabricated frame structure of industrialized housing according to the development status of China’s construction industry.
Therefore, the transformation from traditional construction technology to environmental protection construction technology is the general trend, and the change trend of construction industrialization is also the general direction of development of other industries.
The main component type of partial assembly is prefabricated parts, so some key structural nodes and infilled wall parts need to be completed with the help of pouring work.
However, from the overall perspective, the construction requirements of the joint connection part of the structure are high and the process is complex, so the requirements for construction technology are high.
The disadvantages are poor seismic resistance and low safety.
The structure of the fifth floor is a fabricated integral frame structure, using prefabricated columns, composite beams, slabs, etc.
The integrated frame structure is adopted.
Construction process of industrial assembled residential building 3.1 PC component hoisting and positioning 3.1.1 PC construction process The structure of the third and fourth floors of the project is an assembled integral shear wall structure, using component composite plates, beams, prefabricated wall panels, balcony panels, stairs, etc.
The design should be flexible to ensure smooth connection of the structure.
Structural division and technical analysis of industrial assembled residential buildings 1.1 Division of prefabricated frame structure In the current construction field, prefabricated frame structure is roughly divided into three types: frame type, shear wall type and frame-shear wall type.
Nowadays, with the rapid development of social economy, people’s requirements for buildings are no longer limited to safety and functionality, but also require green and environmental protection.
