This is because the structure may deform to a certain extent due to factors such as foundation settlement, temperature changes, and natural shrinkage of concrete. In order to ensure the stability and service life of the structure, it is crucial to reasonably set expansion joints. Taking the canal project as an example, according to the specifications, a expansion joint needs to be set every 5 meters on the side wall, which undoubtedly increases the difficulty and complexity of formwork support.

However, when using this traditional method to support the formwork at the deformation joint, a series of problems are often encountered.

[0019] The following is a detailed explanation and description of a support device for shaping a deformation joint of the utility model in conjunction with the drawings in the specification.
[0020] like Figure 1-4As shown, the utility model discloses a support device for shaping a deformation joint, including an inner support steel plate 1 and an outer support steel plate 2, and the inner support steel plate 1 and the outer support steel plate 2 are arranged at intervals in front and behind. The inner support steel plate 1 and the outer support steel plate 2 are connected by tension bolts 3. The tension bolts 3 are located in the upper half of the two steel plates (i.e., the inner support steel plate 1 and the outer support steel plate 2), and the two steel plates are tightly connected together, which not only enhances the stability of the structure, but also greatly simplifies the installation process. When supporting the deformation joint, the staff only needs to fix the inner support steel plate 1 and the outer support steel plate 2 at intervals in the specified position, and then shape them in the upper half through the tension bolts 3. Such operation greatly saves the support time and improves the construction efficiency. The setting of the inner support steel plate 1 and the outer support steel plate 2 also fully considers the closure of the deformation joint. The middle part of the inner supporting steel plate 1 is provided with a first concave portion 4 extending toward the outer supporting steel plate 2, while the middle part of the outer supporting steel plate 2 is provided with a second concave portion 5 extending toward the inner supporting steel plate 1. The two concave portions are arranged opposite to each other, and a certain gap is left between them. The bottoms of the two concave portions are both recessed toward the opening direction, forming a cylindrical installation space. A rubber waterstop 8 is inserted into the cylindrical installation space, and the two sides of the rubber waterstop 8 are respectively stuck in the above-mentioned gap. Such a design enables the inner supporting steel plate 1 and the outer supporting steel plate 2 to form a closed space at the deformation joint, effectively preventing the occurrence of slurry leakage and improving the overall molding quality. In addition, the width of the recessed portion between the first concave portion 4 and the second concave portion 5 can be adjusted according to actual needs, effectively controlling the width of the deformation joint to adapt to different deformation requirements. It is worth mentioning that the support device as a whole adopts a detachable connection method, which makes it easy to clean and maintain after demolding. It not only reduces maintenance costs, but also improves construction efficiency; it not only simplifies the installation process and improves construction efficiency, but also ensures the stability and waterproof performance of the structure.
[0021] In one embodiment of the utility model, the inner support steel plate 1 includes a left half inner support steel plate 11, a right half inner support steel plate 12 and a first curved plate 13. The left half inner support steel plate 11 and the right half inner support steel plate 12 are both L-shaped. The left half inner support steel plate 11 and the right half inner support steel plate 12 are symmetrically arranged on the left and right sides. The short sides of the left half inner support steel plate 11 and the right half inner support steel plate 12 are arranged opposite to each other. The first curved plate 13 is bent forward, one side of the first curved plate 13 is welded to the short side of the left half inner support steel plate 11, and the other side of the first curved plate 13 is welded to the short side of the right half inner support steel plate 12. The short sides of the left half inner support steel plate 11 and the right half inner support steel plate 12 and the first curved plate 13 constitute a first concave portion 4.
[0022] The outer supporting steel plate 2 includes a left half outer supporting steel plate 21, a right half outer supporting steel plate 22, and a second arc plate 23. The left half outer supporting steel plate 21 and the right half outer supporting steel plate 22 are both L-shaped. The left half outer supporting steel plate 21 and the right half outer supporting steel plate 22 are symmetrically arranged on the left and right sides. The short sides of the left half outer supporting steel plate 21 and the right half outer supporting steel plate 22 are arranged opposite to each other. The second arc plate 23 is bent backward, one side of the second arc plate 23 is welded to the short side of the left half outer supporting steel plate 21, and the other side of the second arc plate 23 is welded to the short side of the right half outer supporting steel plate 22. The short sides of the left half outer supporting steel plate 21 and the right half outer supporting steel plate 22 and the second arc plate 23 constitute a second concave portion 5.
[0023] The cross-sectional shapes of the first arc plate 13 and the second arc plate 23 are both semicircular, and the first arc plate 13 and the second arc plate 23 are arranged opposite to each other to form a cylindrical installation space.
[0024] Angle brackets 6 are welded to the lower ends of the long sides of the left half outer supporting steel plate 21 and the right half outer supporting steel plate 22. The angle brackets 6 are provided with mounting holes 61 arranged in a straight line, and ground nails 7 are arranged in the mounting holes 61. The ground nails 7 can select different positions of the mounting holes 61, thereby adjusting the fixing position of the outer supporting steel plate 2.
[0025] In one embodiment of the utility model, the left half outer support steel plate 21 and the right half outer support steel plate 22 bend their long sides into a Z shape, and the distance between the left half of the left half outer support steel plate 21 and the left half inner support steel plate 11 is smaller than the distance between the right half of the left half outer support steel plate 21 and the left half inner support steel plate 11. The right half outer support steel plate 22 is the opposite, and the distance between the left half and the right half inner support steel plate 1 is larger than the distance between the right half of the right half outer support steel plate 22 and the right half inner support steel plate 1. When applied to trench projects, the change in its shape forms a variable diameter structure at the deformation joint that is wide in the middle and narrow on both sides. This structure can not only effectively disperse and resist the pressure from the soil, but also provide additional support at the deformation joint, thereby significantly enhancing the firmness of the structure at the deformation joint.
[0026] The long side widths of the left half outer support steel plate 21 and the right half outer support steel plate 22 are exactly the same, while the short side widths remain the same. However, it is worth noting that the width of the long side of the left half outer support steel plate 21 is significantly greater than the length of its short side. In addition, the widths of the left half inner support steel plate 11 and the left outer support steel plate 2 match the width of the short side of the left half outer support steel plate 21. Not only does it ensure the stability of the support structure, but it can also accurately control the thickness of the bottom of the trench of trench-type projects by controlling the width difference between the long side and the short side of the left half outer support steel plate 21 or the right half support steel plate. This control method is both flexible and practical, and can flexibly adjust the size and shape of the support structure according to the needs of the specific project to achieve the best support effect.
[0027] In actual use, see Figure 4 The device uses two sets. The lower end of the outer supporting steel plate 2 is fixed by an angle code 6 and a ground nail 7. The lower end of the adjacent inner supporting steel plate 1 is supported by a wooden beam 100. The width of the groove 200 is limited by the wooden beam 100. The upper ends of the outer supporting steel plates 2 and the inner supporting steel plates 1 in each set are fixed with tension bolts 3 to determine the width of the side wall of the groove 200.
