Precast concrete building system is a modular and modular precast concrete prefabricated building structure system with independent intellectual property rights, which is jointly developed by Hebei Lijian Lizhu Integrated Housing Co., Ltd. and Tsinghua University Architectural Design and Research Institute Co., LTD. The above-ground part of the building is all prefabricated and installed in the factory, and the connection between each structural component is connected by bolts and other mechanical connections, which belongs to the fully assembled prefabricated concrete structural system constructed by the dry method.

Precast concrete housing application scope

It is mainly suitable for low-rise residential projects in areas with seismic intensity of 8 degrees and below 8 degrees (height within 10M), and can also be used for small base station rooms and temporary low-rise office and residential rooms.

Comparison of advantages and disadvantages with other structural systems

Masonry structure: low cost, common materials; However, poor earthquake resistance, poor durability, consume a lot of clay occupy farmland, is not conducive to environmental protection; Should be accepted by the public

Wooden structure: good seismic, changeable shape; But the material is scarce, the fire resistance is poor, the cost is high; Not acceptable to the public

Light steel structure: light weight; High strength; Good ductility, earthquake resistance; Suitable for taller buildings is in the ascendant. The disadvantage is that it is not fire-resistant; Not resistant to rust; Not acceptable to the public

Concrete: material popularization, low cost; Durable, fire-resistant, no corrosion and mildew; High strength and good shock resistance; Should be accepted by the public

Technical features and advantages

First, modular design: modular design, space changes, can meet a variety of household needs.

Second, standardized production: standardized mold, standardized components, standardized production 

Three,Prefabricated construction: modular construction of standardized concrete components, full dry operation, convenient construction.

Green demolition and construction mode

The connection between each structural component in the precast concrete building system adopts mechanical connection methods such as bolts, which makes the installation and disassembly of the building body house very convenient, and changes the large amount of construction waste and building materials made by the destructive demolition method adopted in the process of the original house demolition cannot be used again. True green construction is realized in the process of building and dismantling houses.
