Problems solved by technology

However, for the steel-concrete composite structural beam, in addition to the reinforcement cage, there is also steel in the composite structural beam, which constitutes an obstacle to the installation of the screw, and the cross-section specification of the steel-concrete composite structural beam is large, and the formwork area is also large, so It is difficult to ensure the effective knotting of the formwork by the conventional screw setting method

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0033] The formwork installation method of the steel-concrete composite structure beam of the present invention is to set the tension bolt 07 of the side formwork of the steel beam at the mid-span position of the steel beam, and the tension bolt 07 is divided into two sections and respectively welded on the two sides of the steel beam. side. Moreover, the side templates 08 on both sides of the steel beam are tied by the wall-through screw rods 06 on the upper and lower sides of the steel beam.

[0034] Further, after the hoisting of the steel beam is completed, the formwork support 05 is erected with steel pipes at the same time as the column reinforcement is installed, as an operating platform for installing the beam bottom reinforcement and formwork. After the formwork frame is set up, lay the beam bottom formwork first, then hoist the longitudina...

Abstract

The invention discloses a formwork installation method for a steel reinforced concrete composite structural beam. The formwork installation method belongs to the architecture construction methods, andsolves the problem that the prior art is difficult to ensure that screws effectively pull and tie formworks. According to the formwork installation method, side surface formworks on two sides of a steel beam are pulled and tied by means of through-wall screws on upper and lower sides of the steel beam, a split bolt pulling and tying the side surface formworks of the steel beam is arranged at a midspan position of the steel beam, and the split bolt is divided into two sections which are welded to the two sides of the steel beam respectively, thus the split bolt pulls, ties and supports the formworks by taking the steel beam as a supporting basis, thereby ensuring that the formworks do not shift when concrete is poured, and guaranteeing the quality of the steel reinforced concrete compositestructural beam.

Description

technical field [0001] The invention belongs to a building construction method, in particular to a formwork installation method for a steel-concrete composite structural beam. Background technique [0002] When pouring concrete, the formwork needs to be supported outside the reinforcement cage. In order to fix the formwork and prevent the formwork from shifting during pouring, it is necessary to tie the formwork with screws. However, for the steel-concrete composite structural beam, in addition to the reinforcement cage, there is also steel in the composite structural beam, which constitutes an obstacle to the installation of the screw, and the cross-section specification of the steel-concrete composite structural beam is large, and the formwork area is also large, so It is difficult to ensure the effective knotting of the formwork by the conventional screw setting method. Contents of the invention [0003] The technical problem to be solved and the technical task propose...
