Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a novel steel plate composite shear wall. Background Technology

[0002] Currently, partially encased composite shear walls are a new type of prefabricated steel-concrete composite shear wall. These shear walls do not require vertical or horizontal reinforcement binding, resulting in a simple overall structure. Components can be fabricated in the factory, requiring only splicing and installation on site. This effectively reduces the construction period while ensuring component construction quality, offering significant economic benefits. However, they are prone to out-of-plane stability issues, providing relatively low out-of-plane stiffness. Traditionally, to effectively address this out-of-plane stiffness problem, the intermediate web is thickened, increasing costs. Therefore, we propose a new type of steel plate composite shear wall. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a novel steel plate composite shear wall. By strengthening the truss, the amount of steel plates used in this shear wall is greatly reduced. Furthermore, this shear wall has out-of-plane stiffness and small deformation, improving its economic advantages. Strengthening the truss makes the shear wall structure more robust, and at the same time, strengthening the truss enhances the out-of-plane stiffness of the shear wall itself, greatly improving the out-of-plane stability of the shear wall and significantly increasing its load-bearing capacity, thus solving the problems mentioned earlier.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel steel plate composite shear wall includes a first steel plate on the front side and a second steel plate on the rear side. A first rectangular steel pipe and a second rectangular steel pipe are respectively provided on both sides of the first steel plate. A first connector, a second connector, and a third connector are fixedly welded to the inner side of the first steel plate from left to right. A first fastener, a second fastener, and a third fastener are fixedly welded to the inner side of the second steel plate. A rectangular cavity is formed between the first steel plate and the second steel plate, and a reinforcing truss is provided inside the rectangular cavity.

[0006] Preferably, the reinforcing truss includes a plurality of vertically distributed first reinforcing rods, a plurality of vertically distributed second reinforcing rods, a plurality of vertically distributed third reinforcing rods, a plurality of vertically distributed fourth reinforcing rods, and a plurality of vertically distributed fifth reinforcing rods. The first reinforcing rods are fixedly welded between the first fixing member and the first connecting member, the second reinforcing rods are fixedly welded between the first connecting member and the second fixing member, the third reinforcing rods are fixedly welded between the second fixing member and the second connecting member, the fourth reinforcing rods are fixedly welded between the second connecting member and the third fixing member, and the fifth reinforcing rods are fixedly welded between the third fixing member and the third connecting member.

[0007] Preferably, the first reinforcing rod, the second reinforcing rod, the third reinforcing rod, the fourth reinforcing rod, and the fifth reinforcing rod are all made of steel bars.

[0008] Preferably, the first rectangular steel pipe is fixedly welded to the first steel plate and the second steel plate respectively, and the second rectangular steel pipe is fixedly welded to the first steel plate and the second steel plate respectively.

[0009] Preferably, the rectangular cavity formed between the first steel plate and the second steel plate is filled with concrete filler.

[0010] Preferably, the first reinforcing rod, the second reinforcing rod, the third reinforcing rod, the fourth reinforcing rod, and the fifth reinforcing rod are all installed at an angle.

[0011] This utility model provides a novel steel plate composite shear wall. Compared with the prior art, it has the following advantages:

[0012] 1. This novel steel plate composite shear wall is composed of a first steel plate, a second steel plate, a first rectangular steel pipe, a second rectangular steel pipe, a first connector, a second connector, a third connector, a first fixing component, a second fixing component, a third fixing component, and a reinforcing truss. The reinforcing truss significantly reduces the amount of steel plates used in this shear wall, and the shear wall has out-of-plane stiffness and small deformation, improving its economic advantages. The reinforcing truss makes the shear wall structure more robust, and at the same time, it enhances the out-of-plane stiffness of the shear wall itself, greatly improving the out-of-plane stability of the shear wall and significantly increasing its load-bearing capacity. This steel plate composite shear wall, composed of steel structure and concrete materials, can well meet the needs of low-rise and high-rise residential projects, and the reinforcing truss can simultaneously bear vertical and horizontal loads in actual engineering.
