A prefabricated steel cage quick docking device and its construction method

Abstract

This application relates to a prefabricated steel cage quick docking device, which includes a plurality of vertically arranged lower main bars, a threaded sleeve arranged on the top of the lower main bars, and a vertically arranged upper main bar, and also includes a limit clamp, which includes The left deck and the right deck are arranged symmetrically to each other, and there are limit cavities for limiting the position of the lower reinforcement cage on the left deck and the right deck. The left deck and the right deck are detachably connected. The upper surface of the seat is provided with a tightening assembly for automatically tightening the threaded sleeve. The tightening assembly includes a drive motor vertically arranged on the upper surface of the limit clamp, a drive gear fixed on the output shaft of the drive motor, and a drive gear arranged on the threaded sleeve. The driven ring gear on the peripheral side wall of the sleeve, the driving gear is engaged with the driven ring gear, and the driving motor is detachably connected to the upper surface of the limit clamp. The application has the effect of greatly improving the construction efficiency of butt jointing of reinforcement cages.

Description

technical field [0001] The present application relates to the technical field of building construction components, in particular to a prefabricated reinforcement cage quick docking device and a construction method thereof. Background technique [0002] With the rapid development of China's infrastructure, steel cages, as an important part of building construction components, have been widely used. Generally, during the construction of bridges, culverts or high-rise buildings, ground foundations are required to be piled. Specifically, machine punching or water milling is used to drill deep holes. When the hole depth meets the design requirements, the reinforcement cage is lowered into the deep hole, and finally concrete is poured. [0003] For some ultra-long pile holes, it is necessary to match the ultra-long steel cage model. When the length of the steel cage is long (generally greater than 30 meters), it needs to be made in sections. The reason is that the transportation o...

Problems solved by technology

[0006] However, this construction method is very time-consuming and manpower-consuming. During normal construction, 2-3 construction workers are required to perform tightening operations, and the time spent on the entire tightening process accounts for more than 70% of the entire reinforcement cage installation time, which greatly reduces The overall construction progress of multi-section steel cage butt joint

[0007] In view of the related technologies mentioned above, based on the above analysis, the inventor believes that the construction progress of the steel cage straight thread sleeve connection before improvement is relatively slow, and the construction quality is average
