A herringbone steel bar quick connection sleeve

Abstract

The invention belongs to the technical field of engineering construction, and particularly relates to a herringbone reinforcing bar rapid connecting sleeve. The herringbone reinforcing bar rapid connecting sleeve comprises a shell, driving bevel gears, threaded pipes, a bearing and transition spiral modules, wherein the driving bevel gears are symmetrically arranged in two cylindrical holes No.1;the interior of a stepped bore is fixedly connected to an outer ring of the bearing; an inner ring of the bearing is fixedly connected to the middles of the threaded pipes; conical teeth are arrangedat one end of each threaded pipe; a blind threaded hole is formed in the end surface of the other end of each threaded pipe; the end surface of the other end of each threaded pipe is fixedly connectedto each transition spiral module; and the transition spiral modules are used for clamping one end of a reinforcing bar and driving reinforcing bars to the interiors of the blind threaded holes of thethreaded pipes after the threaded pipes rotate. The herringbone reinforcing bar rapid connecting sleeve can realize the synchronous locking of three reinforcing bars directly inserted in the sleeve with no need of external force clamping by arranging the transition spiral modules at the end parts of the threaded pipes; and the three threaded pipes are driven to rotate through the driving bevel gear. The synchronous locking of the three reinforcing bars is realized during clamping at one time.

Description

technical field

[0001] The invention belongs to the technical field of engineering construction, in particular to a herringbone-shaped steel bar quick connection sleeve. 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 oth...

Embodiment approach

[0028] When working, insert the steel bar into the transitional helical module 5, and the transitional helical module 5 realizes the clamping of the steel bar, and then inserts the inner hexagonal wrench into the inner hexagonal concave hole 211 at the end of the short shaft 21 of the driving bevel gear 2 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 other end of the ba...
