First, the concept of assembly architecture
The assembled building is a concrete structure made of prefabricated concrete members assembled by means of reliable connections, including assembled concrete structures, fully assembled concrete structures and the like. Assembly of buildings in the construction, referred to as the assembly of buildings; in structural engineering, referred to as the assembly structure.
Second, the concept of assembly concrete structure
Assembly of concrete structure refers to the prefabricated concrete components through a reliable connection to connect and with the post-pouring concrete, cement-based grouting material to form an overall assembly of concrete structure, referred to as the overall structure of the assembly.
The assembled concrete structure is suitable for residential and public buildings.
Third, the classification of concrete structure
1, assembly of concrete frame structure
Assembled concrete frame structure, that is, all or part of the frame, beams and columns using prefabricated components, built into the assembly of concrete structure, referred to as the assembly frame structure.
2, assembly of concrete shear wall structure
Assembly of concrete shear wall structure, that is, all or part of the shear wall using prefabricated wall panels to build the assembly of concrete structure, referred to as the assembly of shear wall structure.
3, the assembly of concrete frame - cast - in - place shear wall structure
The assembled concrete frame - the cast - in - place shear wall structure consists of two parts: the integral frame structure and the cast - in - place shear wall (cast - in - place core tube). The frame portion of this construction is made of the same prefabricated assembly technology as the prefabricated monolithic frame structure, allowing prefabricated assembly frame technology to be used in high-rise and super-high-rise buildings. In view of the fact that the overall force of this kind of structure is not enough, at present, the shear wall in the cast concrete frame - cast - in - place shear wall structure can only be cast.
Fourth, the assembly of concrete structure with other structural forms of the scope of comparison
The applicable height of the assembled concrete frame structure and the cast-in-place concrete frame structure is differentiated. Through the comparison of the specifications of the concrete structure and the comparison of the cast-in-place concrete structure, it can be found that,
1) The overall height of the assembly frame structure is the same as that of the cast-in-place concrete frame structure.
2) Assembly of the overall framework - Cast-in-place shear wall structure (shear wall cast, frame part of the prefabricated assembly) with the traditional cast-in-place concrete frame structure
3) The overall structure of the shear wall structure, in the same seismic intensity and cast-in-place shear wall structure difference of about ten meters.
4) When the total shear force of the prefabricated shear wall structure is greater than 80% of the total thickness of the layer, the integral shearing wall structure and the cast-in-place shear wall structure are different.
Fifth, the assembly of concrete structure design of other requirements.
The design of the assembled concrete structure should meet the requirements of the function of the building and the requirements of the safety and applicability of the construction process to determine the reasonable structure and select the appropriate prefabricated component type.
