New connector for formwork assembling

Abstract

The present invention provides a kind of formwork assembling connector for raising formwork assembling quality and speed in building construction. The present invention features that the connector consists of plate bolt in special shape and T-shaped wedged spring board, the former consists of integral bolt head, bolt shoulder, bolt body and bolt tail; while the latter consists of T-shaped head and wedge body with prolate holes matching the bolt head and the bolt shoulder. When the connector is used, the plate bolt is penetrated through the connecting hole in the assembled formwork, the spring board has its prolate holes around the bolt shoulder and inside the bolt head, and the fastened wedge body produces some elastic bending. The present invention has reliable formwork assembling andthus high concrete casting quality.

Description

technical field [0001] The invention belongs to the field of building formwork connecting devices, and relates to a new formwork connector. Background technique [0002] In the prior art, when building formwork, mainly steel formwork, is assembled and connected, most of them use ordinary bolts and nuts perforated to assemble and connect. This traditional connection device has obvious shortcomings: the construction speed is slow, and the formwork assembly The quality is not easy to guarantee, it is easy to be damaged at the construction site, and it is easy to loosen by itself after the earthquake, which sometimes seriously affects the quality of concrete pouring; there are also many companies that use such as: the assembly sleeve disclosed in Chinese patent ZL99205850·3, its structure is: There are double hook feet on the main part, and there are fastening bolts with saddle-shaped plates opposite to the double hook feet. When in use, there must be matching double holes on th...

[0002] In the prior art, when building formwork, mainly steel formwork, is assembled and connected, most of them use ordinary bolts and nuts perforated to assemble and connect. This traditional connection device has obvious shortcomings: the construction speed is slow, and the formwork assembly The quality is not easy to guarantee, it is easy to be damaged at the construction site, and it is easy to loosen by itself after the earthquake, which sometimes seriously affects the quality of concrete pouring; there are also many companies that use such as: the assembly sleeve disclosed in Chinese patent ZL99205850·3, its structure is: There are double hook feet on the main part, and there are fastening bolts with saddle-shaped plates opposite to the double hook feet. When in use, there must be matching double holes on the frame of the template. On the top of the frame of the two templates, then tighten the jacking bolts. The biggest advantage of this connection device is that the construction speed is fast, but there are still obvious shortcomings: the frame of the template must have standard double holes, and it is also necessary to It is easy to be damaged, and it is easy to loosen by itself after being shaken. At the same time, there are strict requirements on the inner size of the double hook feet. After repeated use, both the matching double holes of the formwork frame and the double hook feet themselves will have dimensional deviation due to wear, which will give the template Assembling quality brings unavoidable influence, thereby affects concrete pouring quality; Another example: the fixture scheme disclosed in Chinese patent ZL01271107. For the right half of the clip, when in use, the left and right halves of the clip are aligned on the frame of the template. At this time, the rack on the left half of the clip passes through the groove of the right half of the clip, and then the wedge is removed from the The longitudinal hole of the groove is inserted into and meshed with the transverse rack. When the wedging force is applied, due to the function of the helical teeth, the wedge teeth and the rack are engaged in a lateral displacement, thereby driving the two halves of the clip to be tightly combined with each other. Together; the biggest advantage of this kind of fixture is that the construction speed is fast, the template assembly is fast and reliable, and there is no need to punch holes on the frame of the template, but there are high costs and other unsatisfactory points
