Assembling self-gravity-bearing form board device for large-size H-shaped steel reinforced concrete column and fixing method

Abstract

The invention discloses an assembling self-gravity-bearing form board device for a large-size H-shaped steel reinforced concrete column and a fixing method. Steel casing pipes are erected on studs ofH-shaped steel, the two ends of each steel casing pipe penetrate through plywood form boards and fixed to hoops on the outer sides of the plywood form boards through second bolts to form a self-gravity-bearing structure, force on the H-shaped steel is transmitted to the steel casing pipes through the studs, and the purpose of self-gravity-bearing is achieved; and transverse hoops, lateral transverse hoops, vertical hoops and lateral vertical hoops are further arranged on the outer sides of the plywood form boards, and a whole framework is formed through mutual connection through the hoops to fix the plywood form boards. The assembling self-gravity-bearing form board device for the large-size H-shaped steel reinforced concrete column is simple in structure form, reasonable in design and convenient to machine, and the whole device is recyclable, high in circulating efficiency, reasonable in the designed stress form and capable of adapting to pouring and maintaining stages of structures like large concrete structures and large-size concrete structures and effectively avoiding the issues that form expanding and form drifting are likely to occur in the pouring process of large-size concrete.

Description

technical field [0001] The invention relates to the technical field of structural construction, in particular to an assembly self-supporting formwork device and a fixing method for a large-volume H-shaped steel concrete column. Background technique [0002] During the pouring process of mass concrete, problems such as mold expansion and mold removal are prone to occur, and sufficient attention must be paid during the construction process. When the beam or column of a large concrete structure has a certain inclination angle, the formwork of the inclined beam or column will be more complicated, and the large concrete structure is prone to large deformation during the pouring process, and even cause the scaffolding of the formwork to collapse. Contents of the invention [0003] The purpose of the present invention is to provide a large-volume H-shaped steel concrete column assembly self-supporting force formwork device and fixing method, which has a simple structure, reasonab...
