Composite steel formwork support system and construction method thereof

Abstract

The invention discloses a composite steel formwork support system which comprises panel device and a support device, wherein the panel device mainly comprises a steel formwork panel and an operating platform, and the steel formwork panel is arranged at the upper part of a structural bottom plate and faces towards a building envelope; the inner side face of the steel formwork panel is painted witha release agent, and a construction platform is arranged on the outer side face of the steel formwork panel; the supporting device comprises a first support structure and a second support structure; the first support structure is arranged at the bottom of the steel formwork panel, and the steel formwork panel is connected and fixed with the end part of the structural bottom plate through the firstsupport structure; and the middle of the first support structure is connected with the structural bottom plate through the second support structure. The invention further discloses a construction method of the composite steel formwork support system. The composite steel formwork support system has the beneficial effects that the structural design of the steel formwork panel is reasonable, and allsteel formwork panels can be quickly connected with each other through bolts and are not affected by the size of a side wall; the hoisting times of a crane is reduced, and the operation time of workers is shortened; the wall after molding has less cracks and smooth and even appearance, and the apparent effect is good.

Description

technical field [0001] The invention relates to the technical field of formwork support for a side wall of a main structure of a subway station, in particular to a combined steel formwork support system and a construction method thereof. technical background [0002] In recent years, the construction of urban underground space projects has developed rapidly, and tall formwork support systems have been widely used in the structural construction of underground projects such as subway stations and comprehensive pipe corridors. At present, the wooden formwork support system is the main method for the construction of the side walls of the main structure of the subway station. However, the wooden formwork bracket system requires high assembly accuracy between the formwork, and it is necessary to set up full-wall brackets as the support system for the side wall formwork, which takes a long time; the strength of the wooden formwork is low, and it is prone to large deformation, crack...

AI Technical Summary

Problems solved by technology

However, the wooden formwork bracket system requires high assembly accuracy between the formwork, and it is necessary to set up full-wall brackets as the support system for the side wall formwork, which takes a long time; the strength of the wooden formwork is low, and it is prone to large deformation, cracking at the joints of the formwork, and slurry leakage, resulting in detachment. The appearance quality of the concrete after the formwork is poor, which makes it difficult to control the construction quality of the underground structure; at the same time, the loss of the formwork is large during the repeated use of the turnover, and the economy and environmental protection are poor
