Description

Technical Field

[0001] This utility model relates to the field of shear wall technology, and in particular to a steel plate concrete composite shear wall. Background Technology

[0002] Shear walls are walls in buildings or structures that primarily bear horizontal and vertical loads caused by wind or earthquakes, preventing structural shear failure. Also known as seismic walls or structural walls, they are generally made of reinforced concrete. Steel plate shear walls refer to structures where steel plates are filled between some frame beams and columns on a steel frame foundation to improve structural stiffness and seismic performance. Researchers generally consider this a structural form with good seismic performance. This structure is lightweight, has a fast construction speed, and has been experimentally verified to withstand earthquakes. However, adding steel plates inside reinforced concrete walls increases the difficulty of reinforcement arrangement, binding, and formwork reinforcement, affecting construction progress. CN203808295U describes a composite shear wall of steel-concrete composite tubular walls and double steel plates encased in concrete. It uses a structure with double steel plates, studs, and steel-concrete composite tubular columns, and stiffening ribs inside the double steel plates. This structure has good strength, but suffers from a heavy self-weight and difficulty in compacting the concrete within the double steel plates. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a steel plate concrete composite shear wall, which can solve the technical difficulties in the construction of steel plate concrete shear walls in terms of reinforcement arrangement, binding and formwork reinforcement, and solve the technical problem of difficulty in compaction during pouring.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a steel plate concrete composite shear wall, including a steel plate wall, steel columns fixed on both sides of the steel plate wall, multiple plate surface studs on the steel plate wall, and multiple tie rod holes, stirrup holes and template reinforcement tie bolt holes on the steel plate wall.

[0005] Tie bar holes and stirrup holes are used for tie bars and stirrups that pass through shear walls;

[0006] The template reinforcement tie bolt holes are for tie bolts that pass through the template.

[0007] In the preferred embodiment, multiple vertically arranged stiffening ribs are also fixed to the steel plate wall.

[0008] In the preferred embodiment, multiple horizontally arranged stiffening ribs are also fixed to the steel plate wall.

[0009] In the preferred embodiment, multiple horizontally arranged reinforcing bars are also fixedly installed on the steel plate wall, and the horizontal reinforcing bars are fixedly connected to the vertical stiffening ribs.

[0010] In a preferred embodiment, the stirrup hole is a horizontally oriented elongated hole.

[0011] In the preferred embodiment, the steel column is an "H" shaped steel column, and multiple plate studs are fixed on the front and rear end faces and the end face away from the connection with the steel plate wall.

[0012] In a preferred embodiment, the flange of the steel column is provided with multiple bolt holes for connection to the adjacent steel plate wall assembly.

[0013] In the preferred embodiment, the steel plate wall is divided into a lower steel plate wall and an upper steel plate wall. A steel concealed beam is fixedly installed at the top of the upper steel plate wall, and a horizontal vertical plate is fixedly installed at the top of the steel concealed beam. The horizontal vertical plate is fixedly connected to the upper steel plate wall.

[0014] In the preferred embodiment, concrete covers the outside of the steel plate wall.

[0015] The concrete also contains a single-layer steel mesh with multiple longitudinal bars and multiple transverse bars fixedly connected, or a multi-layer steel mesh cage with multiple longitudinal bars and multiple transverse bars fixedly connected.

[0016] The reinforcing mesh or reinforcing mesh cage is fixedly connected to the slab surface with studs or stiffening ribs;

[0017] The fixed connection includes welded connection, binding connection or bolted connection.

[0018] The steel plate and concrete composite shear wall provided by this utility model, by adopting the above technical solution, has the following beneficial effects:

[0019] 1. This utility model facilitates the fixing of the steel plate wall and the shear wall's steel reinforcement structure by pre-setting tie rod holes, stirrup holes and template reinforcement tie bolt holes in the steel plate wall. It avoids on-site drilling, reduces the construction difficulty of reinforcement layout and template reinforcement, reduces construction time, and improves construction efficiency.

[0020] 2. This utility model divides the steel plate wall into upper and lower sections for segmented hoisting and installation, reducing the weight of each hoisting and lowering the installation safety risk. Furthermore, by setting horizontal vertical plates, the upper steel plate wall can be welded to the lower steel plate wall and the steel hidden beam to form a whole, thereby improving the overall load-bearing performance.

[0021] 3. This utility model fixes the steel mesh or multi-layer steel mesh cage in the concrete to the steel plate wall, which further increases the structural strength of the steel plate concrete composite shear wall.

[0022] 4. In some implementations of this utility model, horizontal stiffening ribs are not provided on the steel plate wall so that the vibrating device can enter the formwork and make the concrete compacted. Attached Figure Description

[0028] Example 1:

[0029] like Figures 1-3 In the present invention, a steel plate concrete composite shear wall includes a steel plate wall, steel columns 2 fixed on both sides of the steel plate wall, multiple plate surface studs 9 on the steel plate wall, and multiple tie rod holes 6, stirrup holes 7 and template reinforcement tie bolt holes 8 on the steel plate wall.

[0030] Tie bar hole 6 and stirrup hole 7 are used for tie bars and stirrups passing through the shear wall;

[0031] The formwork reinforcement tie bolt hole 8 is used for tie bolts to pass through the formwork. This structure facilitates the fixed connection of the steel plate wall to adjacent steel plate walls via the steel column 2, and enhances the strength of the steel plate wall. The provided tie rod hole 6, stirrup hole 7, and formwork reinforcement tie bolt hole 8 allow for convenient placement of reinforcing bars and formwork tie bolts.

[0032] Preferred solutions include Figure 2 In the design, the stirrup hole 7 is a horizontally oriented elongated hole. This structure allows the stirrup to pass through easily without the need to enlarge the hole on-site.

[0033] Example 2:

[0034] Preferred solutions include Figure 2 In addition, multiple vertically arranged stiffening ribs 10 are fixed to the steel plate wall. This structure enhances the vertical stiffness of the steel plate wall.

[0035] Example 3:

[0037] Example 4:

[0038] In the preferred embodiment, multiple horizontally arranged reinforcing bars are also fixedly installed on the steel plate wall, and these bars are fixedly connected to the vertical stiffening ribs 10. This structure increases the strength of the steel plate wall without obstructing the fall of the vibrating device, facilitating the compaction of the concrete. It also prevents the formation of cavities below the horizontal stiffening ribs 11.

[0039] Example 5:

[0040] In the preferred embodiment, the steel column 2 is an "H"-shaped steel column, and multiple plate studs 9 are fixed on the front and rear end faces and the end face away from the connection with the steel plate wall. This structure enhances the connection strength with the concrete.

The horizontal vertical plate 4 is fixedly connected to the upper steel plate wall 5. This structure reduces the weight of each hoisting by dividing the steel plate wall into upper and lower sections for segmented hoisting and installation, thereby reducing installation safety risks. Furthermore, by setting the horizontal vertical plate, the upper steel plate wall can be welded to the lower steel plate wall and the steel concealed beam to form a whole, improving the overall load-bearing performance.

[0044] Example 7:

[0045] In the preferred embodiment, concrete covers the outside of the steel plate wall.

[0046] The concrete structure also includes a single-layer steel mesh with multiple longitudinal and transverse reinforcing bars fixedly connected, or a multi-layer steel mesh cage with multiple longitudinal and transverse reinforcing bars fixedly connected; the choice between a single-layer or multi-layer steel mesh cage depends on the thickness of the shear wall.

[0047] The reinforcing mesh or reinforcing mesh cage is fixedly connected to the slab surface with studs 9 or stiffening ribs;

[0048] The fixed connection includes welded connection, binding connection or bolted connection.
