Tool type concrete door and window formwork support

Abstract

The invention relates to a tool type concrete door and window formwork support, and relates to a door and window formwork project of a concrete wall. The tool type support aims at solving the problems of scattered and complicated operation and components, poor working reliability, and high consumption amount of material and working hours of the existing door and window formwork flexible splicing support. The support consists of two bidirectional support openings and a support rod, wherein the bidirectional support openings respectively consist of an L-shaped left jaw and an L-shaped right jaw which are arranged in a mutual penetrating and sheathing way and can only move in the setting range in a left and right way, and a slope mechanism at the combining part of the support rod and the support openings is used for simultaneously tightening formwork back ribs of six working surfaces of doors and windows at the two sides. The tool type support has the advantages that the concept of replacing the complicated manual operation of flexible splicing support by the bidirectional reinforcing type mechanical limiting through one set of tool at a time is realized, and the tool type support is suitable for non-fair-faced and fair-faced formwork projects; as the structure of the support is simple and toolized, the operation is rapid and reliable, the working quality and turnover rate of the support are improved, and the material and working hour are saved.

Description

technical field

[0001] The invention relates to a concrete door and window formwork support for construction engineering. Background technique

[0002] In the construction of concrete walls of high-rise buildings, loose support is generally used to support and reinforce the formwork of doors and windows, that is, wooden squares plus iron nails or steel pipes plus pull bolts are scattered and reinforced. This reinforcement method has three disadvantages: first, the reinforcement effect is poor, and it is prone to mold expansion or mold angle leakage, which reduces the quality of concrete wall components due to the weak link of doors and windows, and increases the workload of cleaning and repairing for subsequent processes The 2nd, do not form the tool of turnover type, the turnover rate of scattered materials is low, waste materials; This formwork reinforcement technology has not been improved for a long time because the quality and safety weight of door and window formwork ...

Examples

Embodiment Construction

[0015] When supporting the formwork, insert the direct pin 8 into the adjustment hole 7 at the selected adjustment position according to the size of the door window, and insert the wedge plate 6 into the enclosing space 13 of the two-way supporting mouth groove of the mouth and jaw bed at both ends, and simultaneously the left and right jaws at the two ends are forked into two respectively. The template back flute 9 of the side door window is knocked down on the two-way support opening at the higher end, right jaw bed 2 to the right jaw arm 1, left jaw arm 3, and right jaw bed 2 and the template back flute 9 are clamped to complete Formwork support; when removing the formwork, reversely knock the right jaw bed 2 to loosen it, and then remove all parts.
