Truss steel bar double-layer gypsum fiberboard, disassembly-free formwork wall structure and construction method

Abstract

The invention provides a truss steel bar double-layer gypsum fiberboard, a disassembly-free formwork wall structure and a construction method. The truss steel bar double-layer gypsum fiberboard comprises a gypsum fiberboard face board and a gypsum fiberboard bottom board which are arranged parallel to each other. A plurality of rows of steel bar trusses are arranged between the gypsum fiberboard bottom board and the gypsum fiberboard face board. All the steel bar trusses are arranged in parallel. The top ends and the bottoms of the steel bar trusses are inserted into the gypsum fiberboard face board and the gypsum fiberboard bottom board and fixed respectively. A cavity supported by the steel bar trusses is formed between the gypsum fiberboard face board and the gypsum fiberboard bottom board. The problem that a building steel formwork needs to be disassembled in the prior art for building construction is solved, the building construction working procedures are reduced, the assembling speed for wall formworks is greatly increased, the construction efficiency is improved, and construction labor hours and the construction cost are reduced. The strength of the disassembly-free formwork wall structure is higher, and the cavity between the gypsum fiberboard face plate and the gypsum fiberboard bottom plate is filled with any wall filling material, so that a novel composite wall board is formed.

Description

technical field [0001] The invention relates to a floor slab or a wall slab for building construction, in particular to a double-layer fiber gypsum board with truss reinforcement and a wall structure without demolition formwork. Background technique [0002] At present, modern high-rise buildings are towering between cities at an astonishing speed, which is closely related to the development and progress of modern building construction technology. Among them, building steel formwork and cast-in-place concrete wall structure have become the mainstream construction forms. It has simple structure, It has many advantages such as quick assembly, convenient maintenance, labor saving, etc. However, the steel formwork is used as the formwork system. The steel formwork has a large dead weight, requires large lifting equipment, and the cost is high. The steel formwork needs to be dismantled in the later stage of wall construction. After molding, secondary processing such as puttying i...
