Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a shear bar connection structure for a diaphragm wall steel cage. Background Technology

[0002] In traditional diaphragm wall construction, shear bars are usually installed on both sides of the steel cage to improve the overall stability of the steel cage.

[0003] The shear reinforcement bars in a steel cage are typically spaced 3m to 5m apart. They are spot-welded to the sides near the edge of the diaphragm wall, and staggered at intersections. However, this method can lead to hollow areas at intersections, preventing a tight fit with the cage. Furthermore, the spot welding positions are limited, making effective fixation difficult. If the intersection reinforcement bars are broken, the shear reinforcement bars fail to form a cohesive unit, resulting in poor installation.

[0004] Based on this, this utility model proposes a shear bar connection structure for a diaphragm wall steel cage. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a shear bar connection structure for a diaphragm wall steel cage. It adopts a "7"-shaped bar connecting component to effectively form the shear bars into a whole. At the same time, it can form a close fit with the steel cage, and the connection is firm, which effectively improves the overall integrity of the steel cage. There are no voids at the intersection of the shear bars and the connection is firm, which can reduce the risk of the diaphragm wall getting stuck due to falling off or external hanging at voids when lowering the cage.

[0006] The technical solution to achieve the purpose of this utility model is: a shear bar connection structure for a diaphragm wall steel cage, including a first shear bar, a second shear bar, and connecting members. The second shear bar includes a first steel bar and a second steel bar. The two connecting members are fixedly connected to the first shear bar and respectively fixedly connected to the first steel bar and the second steel bar.

[0007] Preferably, the first and second shear bars are each provided with four limiting rings.

[0008] Preferably, each of the four limiting rings is fixedly connected to a positioning plate.

[0009] Preferably, two limiting posts are fixedly connected to the positioning plate.

[0010] Preferably, the two connecting members are respectively provided with two welding points one and two welding points two. The connecting members are connected to the first shear bar through welding point one, and the connecting members are connected to the second shear bar through welding point two.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] In this utility model, the steel bars one and two divided by the second shear bar are rigidly connected to the first shear bar by the "7"-shaped connecting component and the double welding point structure, which completely eliminates the problem of hollowing at the traditional intersection point, realizes the full tight fit between the shear bar and the steel cage, significantly improves the overall stability of the steel cage, and reduces the risk of the diaphragm wall getting stuck due to falling off or external hanging at the hollow point when lowering the cage.

[0019] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0020] This utility model provides an improved diaphragm wall reinforcement cage shear bar connection structure. The technical solution of this utility model is as follows:

[0021] like Figures 1-3As shown, a shear bar connection structure for a diaphragm wall reinforcement cage includes a first shear bar 4, a second shear bar, and connecting members 7. The second shear bar includes a first shear bar 5 and a second shear bar 6. The diameter of the first shear bar 4 is the same as the diameter of the second shear bar. The second shear bar divides the first shear bar 5 and the second shear bar 6 at the intersection. Two connecting members 7 are fixedly connected to the first shear bar 4. The cross-section of the connecting members 7 is in the shape of a "7". The two connecting members 7 are respectively fixedly connected to the first shear bar 5 and the second shear bar 6. Through the "7" shaped connecting members 7 and the double welding point structure, the first shear bar 5 and the second shear bar 6 are rigidly connected to the first shear bar 4 as one unit, completely eliminating the traditional problem of hollowing at the intersection, realizing the full tight fit between the shear bar and the reinforcement cage, significantly improving the overall stability of the reinforcement cage, and reducing the risk of the diaphragm wall getting stuck due to falling off or external hanging at hollow points when lowering the cage.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, four limiting rings 2 are respectively provided on the first scissor reinforcement 4 and the second scissor reinforcement. The cross-section of the limiting ring 2 is arc-shaped, and its arc diameter is equal to the diameter of the first scissor reinforcement 4.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, positioning plates 1 are fixedly connected to the four limiting rings 2 respectively. The positioning plates 1 limit the first shear bar 4 and the second shear bar, which facilitates welding and assembly.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, two limiting posts 3 are fixedly connected to the positioning plate 1, and the limiting posts 3 are used to position the connecting component 7.

[0025] Furthermore, such as Figure 1 and Figure 3 As shown, the two connecting members 7 are respectively provided with two welding points 1 8 and two welding points 2 9. The connecting member 7 is connected to the first shear bar 4 through welding point 1 8, and the connecting member 7 is connected to the second shear bar through welding point 2 9. The first shear bar and the second shear bar are rigidly connected through welding point 1 8 and welding point 2 9.

[0026] The specific working method is as follows: the second shear bar is divided into rebar 1 (5) and rebar 2 (6). The first shear bar 4 is placed obliquely on the two limiting rings 2 of the positioning plate 1. Then, rebar 1 (5) and rebar 2 (6) are placed on the other two limiting rings 2 respectively. One end of rebar 1 (5) and rebar 2 (6) is pressed against the first shear bar 4. Then, the connecting component 7 is fitted onto the limiting post 3, so that its welding point 1 (8) is close to the first shear bar 4 and its welding point 2 (9) is close to the second shear bar. Then, welding is performed at welding point 1 (8) and welding point 2 (9) to complete the assembly of the structure. After the assembly is completed, the structure can be removed from the positioning plate 1 and installed on the steel cage.
