A method to improve the efficiency of building construction

Abstract

The invention belongs to the technical field of engineering construction, and in particular relates to a method for improving the building construction efficiency. A steel connecting sleeve used in the method comprises connecting sleeve bodies, a spring, a locking nut, a locking handle, a clamping module and a screw. Face teeth are arranged in a round area on the stepped surface at one end of eachconnecting sleeve body. The other end of the screw is rotatably connected to one end of the locking handle. A rotating shaft hole in the locking handle is eccentrically disposed with the cylindricalsurface. A first cylindrical hole is formed in the end surface at the other end of the connecting sleeve body. The clamping module is arranged in the first cylindrical hole and used for clamping and locking steel bars inserted into the connecting sleeve bodies. Due to the fact that the face teeth are arranged at one end of each connecting sleeve body, and the rotating shaft hole in the locking handle is eccentrically arranged with the cylindrical surface, the angle between two connecting sleeve bodies can be adjusted. The clamping module is arranged in the first cylindrical hole to clamp and lock the steel bars, and finally fastening connection of the two steel bars can be achieved.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to a method for improving building construction efficiency. Background technique [0002] In the prior art, concrete methods such as welding, binding and overlapping, and mechanical connection can be used for connection of steel bars. The connection of prefabricated reinforced concrete components is usually to realize the connection of steel bars first, and then realize the connection of other parts on this premise. For example, in the connection process of prefabricated components, the steel bars are connected first, and then the surrounding structures such as concrete are poured and connected. If electric welding is used, equipment such as electric welding machine and power cord are needed. The process is complicated and inconvenient to use, especially when working at heights, it is even more inconvenient to pull the power cord and electric welding machine and ot...

Problems solved by technology

[0004] The steel bar connection method used in this technical scheme can realize steel bar connection, and the principle is novel; but the structure of the steel bar connection device used in this scheme is complicated, and the operation is cumbersome, which affects the connection efficiency of the steel bar structure; the connection angle of the steel bar cannot be adjusted, which limits The flexibility of the structure; the connected steel bars need to be threaded at the end in advance, which increases the cost
