[0001] This utility model relates to the field of steel clamping technology, specifically an adjustable steel clamping device for the top of infill wall masonry. Background Technology
[0002] According to the requirements of "Masonry Infill Wall Structure Construction" 22G614-1, when the wall length exceeds 5m, steel clamps are required to reinforce the top masonry. Currently, all existing steel clamps are custom-made, and the inconsistent positional relationship between the wall and beams results in an excessive number of custom-made steel clamp specifications. This increases both processing costs and construction complexity.
[0003] Masonry walls and structural beams generally have three types of positional relationships: inside, outside, and middle. In some special cast-in-place structures, there are also specific dimensional positional relationships, resulting in a wide variety of steel clamp specifications and models, which are inconvenient to manufacture and use. Therefore, this utility model provides an adjustable steel clamp for the top of the infill wall masonry. Summary of the Invention
[0004] To address the problem of inconsistent positional relationships between walls and beams, resulting in an excessive number of custom steel clamp specifications that are inconvenient to manufacture and use, this utility model provides an adjustable steel clamp for the top of infill wall masonry.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable steel clamp for the top of an infill wall masonry structure, comprising:
[0007] C-shaped structural beam fasteners and C-shaped wall fasteners;
[0008] The structural beam clamps are positioned opposite to the wall clamps;
[0009] The structural beam clamps are fixedly connected to the wall clamps, and the position of the wall clamps is adjustable along the length of the structural beam clamps.
[0010] As a further description of the above technical solution:
[0011] The structural beam clamp has a first long groove on its horizontal part, and the wall clamp has a second long groove on its horizontal part. The structural beam clamp and the wall clamp are fixedly connected by bolts, and the bolts are located inside the first long groove and the second long groove.
[0012] As a further description of the above technical solution:
[0013] The horizontal part of the structural beam clamp is provided with a downwardly recessed bending part, and the horizontal part of the wall clamp is provided with a third long groove, which slides in conjunction with the bending part.
[0014] A screw is installed at the bottom thread of the bend;
[0015] A horizontal block is provided on the inner side of the bent portion, below the horizontal part of the wall clip, and at the top of the screw.
[0016] As a further description of the above technical solution:
[0017] The shape of the bent portion is an isosceles trapezoid.
[0018] As a further description of the above technical solution:
[0019] An internally threaded component is fixedly installed at the bottom of the bent portion, and the screw is threadedly engaged with the internally threaded component.
[0020] As a further description of the above technical solution:
[0021] The top of the horizontal block is provided with a protrusion.
[0022] The beneficial effects of this utility model are:
[0023] This utility model, through the design of C-shaped structural beam clamps and C-shaped wall clamps, allows for the adjustment of the relative positions of the C-shaped structural beam clamps and C-shaped wall clamps according to the positional relationship between the masonry wall and the structural beam during use. The two clamps are then fixed together for use, making the adjustable infill wall masonry top clamps versatile. They are applicable regardless of whether the masonry wall is located within, inside, or outside the structural beam, or even in specific dimensional positions. In on-site operations, only one type of adjustable infill wall masonry top clamp needs to be produced to basically meet the needs of the entire project. The standardized adjustable infill wall masonry top clamps are easy to manufacture and reduce costs. Attached Figure Description

[0029] Please refer to Figures 1 and 2, which illustrate an adjustable steel clamp for the top of a masonry infill wall provided in this application embodiment. This clamp is used to strengthen the structure of the masonry infill wall. Specifically, it includes a C-shaped structural beam clamp 1 and a C-shaped wall clamp 2, with the structural beam clamp 1 and wall clamp 2 facing away from each other. The C-shaped structural beam clamp 1 faces upward, and the C-shaped wall clamp 2 faces downward. The structural beam clamp 1 and wall clamp 2 are fixedly connected, and the position of the wall clamp 2 is adjustable along the length of the structural beam clamp 1.
[0030] In use, the relative positions of the C-shaped structural beam clamp 1 and the C-shaped wall clamp 2 are adjusted according to the positional relationship between the masonry wall and the structural beam, and then the two are fixed together for use. Through the above design, the adjustable infill wall masonry top clamp can be universal. It can be used regardless of whether the masonry wall is located in the middle of the structural beam, the masonry wall is located inside the structural beam, the masonry wall is located outside the structural beam, or a special positional relationship with specific dimensions. In on-site operation, only one type of adjustable infill wall masonry top clamp needs to be produced, which can basically meet the usage requirements of the entire project.
[0031] The production and manufacturing of standardized adjustable steel clamps for infill wall masonry is relatively convenient and can also reduce costs.
[0032] Example 1
[0033] Please refer to Figure 1, which shows an adjustable steel clamp for the top of a masonry infill wall provided in an embodiment of this application. It is used to strengthen the structure of the masonry infill wall. Specifically, it includes a C-shaped structural beam clamp 1, a C-shaped wall clamp 2, and bolts 3. The structural beam clamp 1 and the wall clamp 2 are arranged opposite to each other, with the C-shaped structural beam clamp 1 facing upward and the C-shaped wall clamp 2 facing downward. A first long groove 1a is provided on the horizontal part of the structural beam clamp 1, and a second long groove 2a is provided on the horizontal part of the wall clamp 2. The structural beam clamp 1 and the wall clamp 2 are fixedly connected by bolts 3, and the bolts 3 are located inside the first long groove 1a and the second long groove 2a.
[0034] When using, loosen bolt 3, then slide and adjust the relative positions of the C-shaped structural beam clip 1 and the C-shaped wall clip 2, and then tighten bolt 3 to fix the C-shaped structural beam clip 1 and the C-shaped wall clip 2 together.
[0035] Example 2
[0036] Please refer to Figure 2, which shows an adjustable steel clamp for the top of a masonry infill wall provided in an embodiment of this application. This clamp is used to strengthen the structure of the masonry infill wall. Specifically, it includes: a C-shaped structural beam clamp 1, a C-shaped wall clamp 2, a horizontal block 4, and screws 5. The structural beam clamp 1 and wall clamp 2 are positioned opposite each other, with the C-shaped structural beam clamp 1 facing upwards and the C-shaped wall clamp 2 facing downwards. A downwardly recessed bent portion 1b is provided on the horizontal part of the structural beam clamp 1. A third long groove 2b is provided on the horizontal part of the wall clamp 2. The third long groove 2b slides with the bent portion 1b. A screw 5 is threaded onto the bottom of the bent portion 1b. A horizontal block 4 is provided on the inner side of the bent portion 1b, below the horizontal part of the wall clamp 2, and above the screw 5.
[0037] In use, based on the sliding engagement between the third long groove 2b and the bending part 1b, the relative positions of the C-shaped structural beam clamp 1 and the C-shaped wall clamp 2 can be adjusted. Then, by tightening the screw 5, the top of the screw 5 pushes the horizontal block 4 upward, causing the horizontal part of the wall clamp 2 to deform. The protruding part of the horizontal part of the deformed wall clamp 2 is located at the notch of the structural beam clamp 1, thereby restricting the structural beam clamp 1 and the wall clamp 2 from sliding again, thus forming a fixed relationship between the structural beam clamp 1 and the wall clamp 2.
[0038] In one embodiment, the bent portion 1b is an isosceles trapezoid, and the shape of the isosceles trapezoid makes the bottom of the bent portion 1b flat, which facilitates the installation of the internal threaded part 1c.
[0039] In one embodiment, an internally threaded component 1c is fixedly installed at the bottom of the bent portion 1b, and the screw 5 is threadedly engaged with the internally threaded component 1c. The internally threaded component 1c is fixed to the bottom of the bent portion 1b by means of snap-fit or welding.
[0040] In one embodiment, the top of the horizontal block 4 is provided with a protrusion 4a, which is M-shaped, so as to facilitate deformation by squeezing on the horizontal part of the wall clip 2.
