Early-dismantling formwork system and construction method thereof

Abstract

The invention discloses an early-dismantling formwork system and a construction method thereof, and belongs to the technical field of constructional engineering. The early-dismantling formwork system comprises at least four supporting assemblies and a supporting plate assembly, and one supporting plate assembly is erected among the four supporting assemblies; and each supporting assembly comprises a fixing column, a lifting column is movably connected into each fixing column, a limiting piece is fixedly connected to the outer wall of each fixing column, a plurality of limiting holes used in cooperation with the limiting pieces are formed in the outer walls of the lifting columns, fixing plates are fixedly connected to the outer walls of the lifting columns, and positioning blocks are fixedly connected to the upper surfaces, close to the two ends, of each fixing plate. A movable column is movably connected into the top end of each lifting column. A supporting plate cannot fall off during disassembly, potential safety hazards do not exist, meanwhile, damage is not prone to occurring, the service cycle is longer, components such as a cross beam do not need to be erected during erection, overall assembly and disassembly are easy and convenient, working efficiency is high, an early-disassembly formwork support is simple in structure and convenient and flexible to operate, the construction technology is easy to master, the construction speed can be increased, and the construction period can be shortened.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an early demolition formwork system and a construction method thereof. Background technique [0002] The early dismantling formwork system is to reduce the span of the floor with a large span by increasing the supporting points through reasonable supporting formwork, so as to achieve the purpose of "early dismantling the formwork and later dismantling the pillars". The support system consists of two parts. An early demolition device is installed in the floor formwork support system. When the floor concrete reaches the early demolition strength, the lifting bracket of the early demolition device is lowered to remove the floor formwork; the support system is demolished twice, and the first demolition Partial support, forming a floor support layout with a spacing of no more than 2m, and the remaining supports will be demolished for the second time when t...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing early demolition formwork is generally by lowering the lifting bracket, so that the beam on the lifting bracket is lowered for a certain distance. At this time, the floor formwork on the beam will be separated from the floor, and the floor formwork will fall freely to the ground However, the above-mentioned scheme has the following disadvantages: when the floor formwork falls during disassembly, it is easy to hit the staff, which poses a safety hazard. The floor formwork falls freely to the ground, resulting in a high damage rate of the floor formwork. The beams also need to be removed during the floor formwork, which further increases the difficulty of the disassembly work and is more cumbersome
