Internally arranged steel plate support for light steel assembled wallboard

Abstract

The invention relates to a steel support, particularly relates to an internally arranged steel plate support for a light steel assembled wallboard, and aims to solve problems that the wallboard dead weight is large, steel plate supports are not easy to check and change after severe earthquakes, and wallboards cannot be used repeatedly in reinforced concrete wallboard internally arranged un-bonded steel plate supports. Two first stiffening ribs are welded along the support length direction at two ends of a steel plate support body; the steel plate support body and a perforated steel base plate are arranged between two steel plates with rectangular grooves arranged at two ends and fixedly connected through a plurality of high-strength bolts; the first stiffening ribs at two ends of the steel plate support body are inserted into rectangular grooves arranged at two ends of first rectangular steel tubes; a plurality of second rectangular steel tubes form two matts frames, each of the matts frames is fixedly connected with one of the steel plates and one of the first rectangular steel tubes, and the two matts frames are fixedly connected with a plurality of connection steel plates; and profiled color steel sheets are arranged on the outer sides of the first rectangular steel tubes and the second rectangular steel tubes. The internally arranged steel plate support for the light steel assembled wallboard is used as a central support and a partition wall simultaneously in a support steel frame with seismic resistance requirements.

Description

technical field [0001] The present invention relates to a steel support. Background technique [0002] In the existing wall panels with built-in unbonded steel plate supports, the wall panels are made of reinforced concrete by integral casting. The wall panels have a large self-weight, and it is difficult to inspect and replace the steel plate supports after a major earthquake, and the wall panels cannot be reused; In addition, the concrete wall panels are easy to bend and punch and crack, resulting in brittle failure, which deteriorates the ductility and energy dissipation capacity of the steel plate support; when the wall panel is poured with concrete, it is difficult to control the straightness of the steel support due to the need to vibrate the concrete. It is likely to cause the steel support to have a large initial bending deformation during the component forming process, which is extremely unfavorable for the force of the built-in support of the wall panel.

Problems solved by technology

[0003] The invention provides a built-in steel plate support of a light steel assembled wall panel, which solves the problem that the existing reinforced concrete wall panel has a large self-weight, it is difficult to check and replace the steel plate support after a major earthquake, the wall panel cannot be reused, and it is difficult to replace the built-in steel plate. The initial bending deformation of the support is controlled, and the concrete wall panel is easy to bend, punch and crack, and brittle failure occurs, which deteriorates the ductility and energy dissipation capacity of the steel plate support
