Rotating control overall formwork erecting and releasing method and mechanical system thereof

Abstract

The invention discloses a rotating control overall formwork erecting and releasing method and a mechanical system thereof. The rotating control overall formwork erecting and releasing method comprisesthe following steps that a rocking handle on a main rotating shaft is rotated forward to drive the main rotating shaft to rotate to enable tensile transmission devices to drive relevance transmissionrods connected with the tensile transmission devices to push cylinder body inner formworks all around outwards, so that the cylinder body inner formworks are moved to be combined with cylinder body outer formworks to achieve a wall thickness size required by construction. According to the rotating control overall formwork erecting and releasing method and the mechanical system thereof, the structure characteristics of arc-shaped grooves of oval disks of the tensile transmission devices are utilized, when the main rotating shaft is rotated, steel balls at the ends of the relevance transmissionrods are enabled to slide along the inner parts of the arc-shaped grooves, the separation distances between the relevance transmission rods and the cylinder body inner formworks are different when the steel balls are located at different positions in the arc-shaped grooves due to the structure characteristics of the oval disks, and thus the cylinder body inner formworks can be pushed outwards orbe loosened through inward constriction.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a method for demoulding an integral support with rotation control and a mechanical system thereof. Background technique [0002] Since the development of formwork engineering for high-rise buildings, the degree of automation of construction operations has reached a considerable level. For example, table formwork systems, quick-installation and quick-disassembly systems, etc., all use the means of overall disassembly and assembly to achieve the goal of saving labor and time and improving efficiency. However, as a part of the core tube structure that must be cast-in-place, the formwork of the elevator shaft wall is affected by the internal space, especially the inner right angle. The formwork bites each other at the corners, and cannot be assembled as a whole for overall lifting. It can only be assembled in bulk, which is labor-intensive It is time-consumi...

However, as a part of the core tube structure that must be cast-in-place, the formwork of the elevator shaft wall is affected by the internal space, especially the inner right angle. The formwork bites each other at the corners, and cannot be assembled as a whole for overall lifting. It can only be assembled in bulk, which is labor-intensive Time-consuming and affecting the construction progress of the entire layer of formwork

In the prior art, there is a method of using aluminum alloy corner formwork, but after the construction of the third to fourth floors, the aluminum alloy corner formwork is deformed by the impact of concrete pouring, and the angle formwork is stuck after the initial setting, resulting in the inability to lift the inner formwork as a whole. Still forced to go back to the bulk and dismantling approach, ultimately failing to break out of the old paradigm
