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

specific Embodiment approach 1

[0014] Specific implementation mode one: as Figure 1-11 As shown, the built-in steel plate support of the light steel assembled wallboard in this embodiment includes a steel plate support body 1 and a light steel assembled wallboard, and two first stiffeners 12 are welded on both ends of the steel plate support body 1 along the length direction. , the two first stiffeners 12 located at the same end of the steel plate support body 1 are symmetrically and vertically arranged with respect to the steel plate support body 1, the light steel assembled wall panel is composed of a wall panel skeleton and two pressed color steel plates 5, and the wall panel skeleton includes Two first rectangular steel pipes 2, two steel plates 7, two perforated steel backing plates 10, two perforated adjustment backing plates 11, multiple second rectangular steel tubes 4, multiple second stiffeners 3, multiple high-strength Bolts 8 and a plurality of connecting steel plates 9, a steel plate supportin...

specific Embodiment approach 2

[0019] Specific embodiment two: In this embodiment, the upper end of the first stiffener 12 located at the lower end of the steel plate support body 1 is in close contact with the upper ends of the first rectangular groove 7-1 and the second rectangular groove 2-1 at the lower part; the steel plate support body 1 The lower end of the upper stiffener 12 and the lower ends of the upper first rectangular groove 7 - 1 and the lower end of the second rectangular groove 2 - 1 leave a gap along the axial direction of the steel plate supporting body 1 . With such a design, the light steel assembled wallboard can pass the self-weight of the wallboard to the steel frame through close contact with the first stiffener 12 at the lower end of the steel plate support body 1, which is conducive to supporting force; the first stiffener 12 of the steel plate support body 1 There is a gap along the axial direction of the steel plate support body 1 at the lower end, which can realize the free shor...

specific Embodiment approach 3

[0020] Specific implementation mode three: as Figure 6 As shown, each matts frame in this embodiment is welded by a plurality of second rectangular steel pipes 4 . With such a design, two well-integrated wall panel skeletons can be formed on both sides of the front and back of the wall panel. Other compositions and connection methods are the same as those in Embodiment 1 or 2.

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 invention relates to a steel support. Background technique [0002] In the existing wallboard built-in unbonded steel plate support, the wallboard is made of reinforced concrete through integral pouring, the wallboard has a large dead weight, it is difficult to check and replace the steel plate support after a major earthquake, and the wallboard cannot be reused; In addition, concrete wall panels are prone to bending and punching cracking, resulting in brittle failure, which deteriorates the ductility and energy dissipation capacity of the steel plate support; when the wall panels are 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 a large initial bending deformation of the steel support during the component forming process, which is extremely unfavorable for the force of the built-in support of the wall panel.
