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 ...

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.
