A tool type concrete door and window formwork support

Abstract

A tool type concrete door and window formwork support relates to the door and window formwork engineering of concrete walls. The tool-type support is used to solve the problems of scattered and complicated operations and components, poor work reliability, and high consumption of materials and working hours in the existing door and window formwork supports. The support is composed of 2 pieces of two-way support ports and 1 piece of support rod; the two-way support port is composed of L-shaped left and right jaws that pass through each other and can only move left and right within the set range, through the joint of the support rod and the support port The inclined plane mechanism fastens the formwork back flute of the six working faces of the doors and windows on both sides at the same time; it realizes the idea of ​​using a set of tools to complete the mechanical limit work of two-way reinforcement at the same time to replace the complicated manual operation of loose support. It is applicable to formwork works of non-clear-faced concrete. Due to the simplicity and instrumentation of the support structure, the operation is fast and reliable, the work quality and turnover rate of the support are improved, and materials and working hours 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 ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of poor reinforcement reliability caused by the loose reinforcement technology of concrete door and window formwork, and at the same time solve the problems of high man-hour consumption and low turnover rate of support materials, the invention provides a tool-type concrete door and window formwork support, which can simplify the support Reinforcement work, improve the use efficiency of formwork support, formwork support efficiency and concrete component quality, and reduce costs
