Concrete prefabricated panel, prefabricated building formed by same and construction method

Abstract

The invention discloses a concrete prefabricated panel and a prefabricated building formed by the same. A nonpenetrating transverse hole is formed in the panel. The panel adopts a structure that the transverse hole is preserved in the edge rib of the panel, a horizontal steel bar meeting the splicing length required by codes for architectural and structural design is inserted into the hole, a transverse hole penetrating the whole panel is not required to be formed, the splicing of a horizontal steel bar between prefabricated panels can be achieved, the transverse transfer requirement is met, and the requirement of an earthquake resistant code of architectural design is met. The length of the inserted horizontal steel bar is greatly shortened, the cost is lowered, the workload and construction difficulty for penetrating the penetrating transverse steel bar are reduced, and the method is simple to implement, simple and effective, an excellent earthquake resistant effect can be achieved, and meanwhile the prefabricated panel is more convenient to produce and manufacture and higher in quality.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a concrete prefabricated wall panel and the buildings formed therefrom. Background technique [0002] At present, in order to improve the problems of slow construction speed and messy construction site caused by the traditional building construction method of binding steel bars first and then pouring concrete, the construction industry has implemented industrialized construction methods, which not only increase the speed, but also make the construction site clean and tidy. And can save energy and reduce emission, protect the environment. [0003] In the industrialized construction method, large-area ordinary walls, corners, and walls where doors and windows are installed are all assembled with prefabricated components. Among them, the prefabricated components assembled into walls for installing doors and windows are not only complex in structure, but also if the design is ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: (1) the number of horizontal steel bars and vertical steel bars that need to be pierced is very large; (2) when enclosing the building, if the length of the wall exceeds 5 meters, or even reaches more than 10 meters, then The transverse reinforcement needs to be passed from one end to the other end of the long tunnel, and the construction is very difficult

The disadvantages of this method are: (1) the workload of welding the horizontal reinforcement of the wall body and the embedded parts and checking the solder joints is very large, and the production cost is high; (2) the post-cleaning and protection work of the embedded parts is very difficult; ( 3) The amount of cross-tie bolts is very large, and the on-site construction workload is also very large, including the screwing of the cross-tie bolts, the detection of the amount of screwing, the inspection and retest of the cross-tie bolts, etc.; (4) The appearance of the components is complex, The workload of concrete filling in the later period is relatively large; (5) Because there is no horizontal hole inside the component, the penetration of concrete is poor, resulting in the stability and earthquake resistance of the building wall cannot meet the requirements of high-rise buildings, especially those with more than 15 floors. Buildings; (6) The size of the longitudinal circular holes in the wall panels is small, which is not convenient for pouring and vibrating concrete, and cannot be placed in column steel bars, resulting in that the strength and seismic performance of the building walls cannot meet the requirements of high-rise buildings, especially It is a building with more than 15 floors
