Problems solved by technology

[0003] In order to solve the problem in the prior art that connecting two steel bars through a sleeve can only be done manually, the invention provides a device and a construction method for connecting two steel bars through a sleeve, which uses a machine instead of manually twisting the sleeve, so that the two steel bars can be connected through the sleeve. The steel bars are connected together, which saves labor and time, and can also overcome the problems of over-tightening, missing-tightening, and unreliable screwing during manual operation.

Abstract

The invention provides a device used for reinforcing steel bar sleeve connection and a construction method. The device comprises first and second clamping devices which are connected through a connecting rod, a detachable conveyor belt, a jacking device, a motor and a speed reducer, wherein notches are formed in the top surfaces of the clamping devices. In use, a reinforcing steel bar is placed into the notch of the first clamping device, the other reinforcing steel bar is placed into the notch of the second clamping device, and the detachable conveyor belt sleeves a sleeve; the ends, close tothe sleeve, of the two reinforcing steel bars are primarily connected to the sleeve; the reinforcing steel bars are clamped by the first clamping device and the second clamping device; the jacking device between a fixing device and a motor base is jacked; and the motor is started to drive the speed reducer, the speed reducer drives the conveyor belt, the conveyor belt drives the sleeve to rotateand screw up, so that the two reinforcing steel bars are connected together through the sleeve. The device uses a machine instead of manual operation for sleeve twisting, so that the two reinforcing steel bars are connected together through the sleeve, and therefore, time and labor are saved; and meanwhile, the problems such as over-twisting, twisting omission and insecure twisting during manual operation also can be solved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a device and a construction method for connecting steel bar sleeves. Background technique [0002] With the development and progress of the construction industry, there are fewer and fewer construction workers who are willing to engage in grassroots construction, resulting in higher per capita labor costs and higher input costs. At the same time, with the rapid development of science and technology, more and more labor is being mechanized Instead, the current construction projects are mainly reinforced concrete structures, and the production and installation of steel bars occupy a particularly important position. The speed of steel bar installation directly affects the construction progress of the entire project, especially the connection speed of straight thread sleeves is particularly important. In the current construction, most of the connections of the straight...
