Steel truss formwork support structure for suspended structure and installing method of steel truss formwork support structure

Abstract

The invention discloses a steel truss formwork support structure for a suspended structure and an installing method of the steel truss formwork support structure. A main stress component of a system consists of a rectangular space truss, and comprises end part trusses, truss standard sections, connecting trusses and diagonal draw bars, wherein each end part truss is used at a connecting part of each truss end part and a main body structure; each truss standard section is used for truss extension; each connecting truss is used in a position, with the length being smaller than that of one truss standard section, of the middle part of each truss and is used for connecting the truss standard sections arranged at the two sides; each diagonal draw bar is made of novel level-3 steel; and the length of each diagonal draw bar can be regulated through rotating a corresponding sleeve arranged at the end part. The support system adopts industrialized and standardized production, can be repeatedly used, has high economical efficiency, and can adapt to formwork supporting of connected suspended structures with different spans and different structural forms. An installing method of adopting cable-stayed suspension installation and laying an operation platform during the installation is adopted, so that the integral stability of the whole support system in the installing process can be improved; the construction is convenient; and the safety is high.

Description

technical field [0001] The invention mainly relates to a suspended formwork support structure, which is suitable for the suspended formwork support of a conjoined structure. Background technique [0002] Suspended structures such as cantilevered structures, portal-style conjoined structures, high-altitude recessed sky garden structures, and tall indoor shared space structures are more and more widely used in modern buildings. The span is large and the general structure is thick, and the local suspended structure and the main structure are unilaterally or multilaterally embedded. In the past construction, the truss formwork system that has been used more often includes truss type, cable-stayed truss type, etc. Generally, the supporting platform system is formed by hoisting to high altitude after welding on the ground. [0003] Due to the various shapes of suspended structures in high-rise buildings, almost all existing formwork support structures can only be used once. F...

Problems solved by technology

This construction method has poor applicability and requires a certain floor width for construction operations. It cannot be used for towers with shear walls at both ends. The load applied to the floors during the construction process is relatively large, and the support system cannot be reused. Economic benefits Difference
