Problems solved by technology

[0002] At present, the use of prefabricated buildings in the field of engineering construction is becoming more and more common. However, due to the limitation of the connection method, the splicing of concrete prefabricated components can only be spliced ​​in one direction at present. In the main connection direction, common methods such as grouting sleeves are used to realize the connection. Finally, the components are generally connected by cast-in-place in other directions. For example, there is a horizontal cast-in-place area in the lateral connection of the shear wall structure; this kind of incomplete prefabricated assembly structure can not effectively improve the prefabricated assembly rate. It also makes the various processes such as component processing, transportation, assembly and on-site concrete pouring more complicated and difficult, which not only prolongs the construction period but also increases the project cost.
[0003] In order to achieve the purpose of multi-directional splicing of concrete assembly building structural components, there is a way to use bolt connection, but the bolt connection between concrete prefabricated components needs to use a steel component or a transition component such as a beam to achieve internal force transmission, and the bolt connection is not only Its own size is large, and because it needs a large installation and operation space, the section of the joint surface of the component is also greatly weakened by the reserved hole, so the number of bolts on each connection surface is greatly limited; at the same time, the concrete prefabricated components The bolt connection method used is not a direct connection between steel bars, but an indirect force transmission system, and the internal force transmission efficiency of the structure is low
