Construction method of tall formwork symmetrical suspension climbing triangular truss support system

Abstract

The invention relates to a construction method of a tall formwork symmetrical suspension climbing triangular truss support system. The main construction steps include vertical slideway installation, triangular truss assembly, triangular truss installation, triangular truss climbing, and beam formwork and support installation. An under beam scaffold in the traditional formwork support system is substituted by a tripod which is symmetrically suspended and combined with pulling and bracing, a plurality of tripods are pulled and combined to form a triangular truss, and a hydraulic climber is further applied to realize an automatic lifting of the triangular truss. The operation space beside and under the beam is large, the construction safety is high, the consumption of steel pipes and fasteners is less, the operation is convenient and the recycling rate of components is high, thereby overcoming the problems such as large supporting and disassembling workload, small operation space, long construction period and unsafe security in the construction of the traditional formwork support system, and the economic and technical benefit is remarkable.

Description

technical field [0001] The invention relates to a construction method for a symmetrical suspension climbing triangular truss support system of a tall formwork, which belongs to the field of construction engineering and is suitable for the construction of a beam-slab support project of a tall formwork. Background technique [0002] In the face of large-span reinforced concrete structure projects, tall and large formwork must be used in the project, and the construction of tall and large formwork is risky, and there are many matters to be paid attention to. The traditional scaffolding support system has the following problems: First, when inspecting, removing formwork, and transporting materials on both sides of the concrete beam, the construction is extremely inconvenient due to the small operating space under the beam and on the side of the beam; Next, scaffolding needs to be set up, which leads to a large amount of steel pipes and fasteners in the project; thirdly, the heav...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of small operating space under the beam, large amount of steel pipes and fasteners, complex construction operation and long period in the construction technology of the traditional scaffolding support system, and propose a symmetrical suspension climbing triangular truss support system for tall formwork The construction method of this support system replaces the under-beam scaffolding in the traditional formwork support system with a symmetrically suspended triangular truss. After the vertical slideway is installed in place and the triangular truss is assembled and installed, the triangular Raise to the design level, further install the beam formwork and complete the pouring of the beam concrete
