1.3 analysis of construction materials of integrated cast frame structure of industrialized residence at the present stage, due to the differences in the characteristics and functions of various materials, the construction materials of cast frame structure can be divided into two categories according to the structural system, one is the heavy structural system, and the other is the light structural system.

Among them, the frame type cast structure is mainly composed of precast beam members, slab members and infilled walls, which are connected by pouring concrete.

With the rapid development of social economy, people’s requirements for buildings are no longer limited to safety and functionality, but also green and environmental protection.

This kind of structure has the characteristics of simple operation, low construction cost and high construction efficiency.

Wire Lifting Loop

The frame shear wall structure combines the advantages of the above two structures and has strong flexibility and excellent seismic performance.

The 5th floor structure is a cast integral frame structure, using precast columns, composite beams, plates, etc.

The shear wall structure is mainly composed of plate members and cast walls.

Generally speaking, because the hoisting accuracy of precast components on the first floor will have an impact on the reinforcement positioning of the transfer floor to a certain extent, the sequence of each link of the workflow is closely related to the hoisting quality and accuracy.

The biggest feature of light structural materials is small quality and simple processing.

Now it has been widely used in the construction of residential integral assembled structure.

Parthree industrial assembled residential building construction process 3.1pc component hoisting and positioning 3.1.1pc construction process the structures of the 3rd and 4th floors of the project are cast integral shear wall structures, using component laminated plates, beams, precast wall panels, balcony panels, stairs, etc.

However, from the perspective of the whole, 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 3rd and 4th floors are apartment houses and the 5th floor is service supporting houses.

The design of precast frame structure is consistent with the development direction of the construction industry at this stage, but according to the development situation, because China’s construction industry 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 promotion speed of industrialization need to be improved.

A residential project has a construction area of 119724.35m2, including supporting service rooms on the 3rd, 4th and 5th floors and underground garage.

The structure has the advantage of separating different house types, and is widely used in high-rise buildings at this stage.

From the actual situation, whether it is the effect or material performance, the comprehensive ability is stronger.

It is often used in the construction of office buildings, residential buildings and commercial buildings.

The 5th floor has 1 floor underground, 4 floors above the ground, and the overall building height is 17.85m, The integrated frame structure is adopted.

Most of them are used in small-scale residential design, such as grid structure.

In practical application, light materials have flexibility and will not prolong the construction period, It is conducive to controlling the construction time.

3.1.2 steel bars are reserved for the transfer floor.

It adopts an integral shear wall structure.

According to the previous construction experience, the following measures can be taken: (1) surveying and setting out.

The disadvantage is poor seismic capacity and low safety.

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 the development of other industries.

The standard construction process is formulated according to the characteristics of the project, as shown in Figure 1.

From the effect, the safety and seismic capacity of partial assembly are better than that of full assembly process.

The 3rd and 4th floors have 1 floor underground, 18 floors above the ground, and the overall building height is 57.16m.

1.2 division of assembly degree in the construction of overall assembly frame structure of industrialized housing at the present stage, according to the difference of assembly structure system, the assembly degree can be divided into full assembly and partial assembly.

All construction components of the full assembly process shall be designed and completed by professional manufacturers and handed over to professional personnel for installation.

The latter comes from a wide range of materials.

This paper studies the industrialized assembled residential building system and its construction technology, and is determined to promote the realization of housing industrialization in China and provide reference for people in relevant industries.

The industrialization of precast housing construction technology has become the inevitable trend of the development of the construction industry, and it is also one of the manifestations of the modernization of China’s construction industry.

The former is mostly used in composite buildings, but the system has the defects of long time-consuming and complex construction processes.

Most light structural materials, such as glass fiber and wood, can be used in the construction of the system.

The design should be flexible to ensure the smooth connection of the structure.

The third floor of building 3 and 4 is the transfer floor, and the first floor of Building 5 is the transfer floor.

After the installation of the platform formwork and the binding of the floor reinforcement, specifically, the construction tools shall be used to measure and control the positioning line of the reserved reinforcement according to the previous reserved control points of the floor..

The main component type of partial assembly is precast parts, so some key structural nodes and filled walls need to be completed with the help of pouring.

Compared with the general construction strategy, housing industrialization can speed up the construction speed, improve the construction quality to a certain extent, and ensure that the building has environmental protection performance and strong functionality, which is the development goal of China’s construction industry at this stage.

PartOne industrial assembled residential building structure division and technical key points analysis 1.1 precast frame structure division in the current construction field, the precast frame structure is roughly divided into three categories: frame assembled type, shear wall type and frame shear assembled type.

In this regard, according to the development status of China’s construction industry, it is very necessary to study the construction technology of integrated cast frame structure of industrialized housing.
