Counter bracing device for installation of pouring formwork of concrete walls

Abstract

A counter bracing device for installation of the pouring formwork of concrete walls belongs to the technical field of concrete pouring construction. The counter bracing device comprises two wall bolts, casing pipes, a joint and clamping boards. The wall bolts are connected through the joint; the casing pipes sleeve the wall bolts; the ends of the wall bolts, which are connected with the joint, are provided with threads, both ends of the joint are provided with internal thread holes matched with the threads of the wall bolts, and the wall bolts and the joint are threadedly connected; the other ends of the wall bolts are provided with radial ring-shaped grooves and axial square adjusting internal holes, and the depth of the square adjusting internal holes is smaller than the distance between the ring-shaped grooves and the end portions of the wall bolts; each clamping boards is provided with a snapping hole which is large in the middles and the small at both ends, the middle of the snapping hole is matched with the corresponding wall bolt, and both ends of the snapping hole are matched with the neck portion formed by the ring-shaped groove of the wall bolt. The counter bracing device for installation of the pouring formwork of the concrete walls is reasonable and simple in structure and easy to produce and manufacture, and according to the concrete walls of different widths, can be adjusted through the wall bolts and the joint, thereby being convenient to use.

Description

technical field [0001] The invention relates to a fixing device for installing formwork for concrete slab wall pouring, and belongs to the technical field of concrete engineering pouring construction. Background technique [0002] The existing concrete slab wall pouring formwork installation and fixing device is composed of wall-through rods or pull bolts, wooden beams, pressure plates, and nuts. Insert into the keyholes at both ends of the wall-through rod to limit the distance between the two steel formworks, keep the two steel formworks parallel, and then pour concrete between the two steel formworks to form the wall. And the pull bolt of existing fastening formwork generally is according to the width of itself in the field concrete product construction, processes single quite long bolt, and formwork both sides adds common nut fastening with butterfly clamp. After the concrete products are poured, if there is no concrete product of the same width, the wall-through rods o...

AI Technical Summary

Problems solved by technology

After the concrete products are poured, if there is no concrete product of the same width, the wall-through rods or pull bolts of this length are useless, or the longer wall-through rods or bolts are cut and processed to meet the thinner concrete The requirements for pouring and use of the product not only need to waste a lot of raw materials, but also need to be threaded at both ends, and repeated processing wastes manpower and material resources
