Embodiment approach

[0041] When in use, the steel bar is inserted into the transitional helical module 5, and the transitional helical module 5 realizes the clamping of the steel bar, and then an inner hexagonal wrench is inserted into the inner hexagonal concave hole 211 at the end of the short shaft 21 of the driving bevel gear 2 to rotate to drive the driving bevel gear 2 Rotate, drive bevel gear 2 to drive threaded pipe 3 to rotate through gear meshing, threaded pipe 3 drives transitional helical module 5 to rotate, transitional helical module 5 transmits the steel bar to the threaded blind hole 32 of threaded pipe 3, and then realizes the connection between the steel bar skeleton Herringbone connection, at the same time, the three steel bars can be directly inserted into the sleeve without external force clamping, and synchronous locking can be realized; the first implementation of the transitional helical module 5: after the steel bar is inserted into the transitional helical module 5, the ot...

Abstract

The invention belongs to the technical field of engineering construction, and in particular relates to a method for improving the connection efficiency of a building steel framework. A steel connecting sleeve used in the method comprises a casing, driving bevel gears, threaded pipes, bearings and transition spiral modules. The driving bevel gears are symmetrically installed in two first cylindrical holes. The threaded pipes are rotatably connected in stepped holes through the bearings. One end of each threaded pipe is provided with a conical tooth, and the other end surface of the threaded pipe is provided with a threaded blind hole. A transition spiral module is fixedly connected to the other end surface of each threaded pipe and used for clamping one end of a steel bar and transferring the steel bar into the corresponding threaded blind hole of the threaded pipe after the threaded pipe rotates. By means of the transition spiral modules arranged at the ends of the threaded pipes, synchronous locking of three steel bars directly inserted into the sleeve can be achieved without clamping by external force. The three threaded pipes are driven to rotate by the driving bevel gears to achieve synchronous clamping of the three steel bars by clamping once.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and specifically relates to a method for improving the connection efficiency of building steel bar skeletons. 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...
