Description

TECHNICAL FIELD

[0001] The present application relates to the trench support field, in particular to a trench support combination structure and a using method thereof. BACKGROUND

[0002] When excavating a trench, when the trench is excavated to a certain depth, the trench needs to be supported to prevent accidents caused by trench collapse, so a trench support combination structure needs to be used for support.

[0003] A patent No. CN208792337U of China discloses a trench support structure, comprising two grid-shaped guard plates and a plurality of support rods arranged between the two guard plates, and the two ends of each support rod are detachably connected with the side walls of the two guard plates.

[0004] The above-mentioned patent can be threaded and spliced between the connecting rods during use, facilitating the splicing of the connecting rods and ensuring the stability of the connection between different connecting rods, but since each section of the force rod and the connecting rod need to be threaded, the support combination structure is more complicated to assemble, which affects the speed of adjusting the distance between the guard plates according to the width of the trench, and since the height of the existing guard plate is fixed, the height of the guard plate cannot be adjusted according to the trench excavation depth, thereby causing limitations in the use of the trench support combination structure. SUMMARY

[0005] The purpose of the present application is to provide a trench support combination structure and a using method thereof to solve the above problems.

[0006] The present application achieves the above-mentioned purpose by the following technical solutions: A trench support combination structure, comprising a support plate one and a support plate two, the support plate one and the support plate two are symmetrically installed with a support frame and a connecting frame on opposite side walls, the connecting frame is provided with a bearing seat on the side wall facing the support frame, a threaded hole is formed in the side wall of the support frame, a screw rod is connected between the threaded hole and the bearing seat, a sliding groove is formed in the opposite side walls of the support plate one and the support plate two, a fixed column is symmetrically fixed in each sliding groove, an adjusting plate is connected in the sliding groove, a connecting groove is formed in the adjusting plate corresponding to the fixed column, a fixed hole is formed in the side wall of the adjusting plate, an adjusting hole is formed in the sliding groove corresponding to the fixed hole, and a fixed bolt is connected through the adjusting hole in the fixed hole.

[0007] Further, the support plate one is bolted to the support frame, the support plate two is bolted to the connecting frame, and the support frame and the connecting frame are both U-shaped structures.

[0008] By adopting the above technical solutions, the first support plate can more firmly fix the support frame, and the second support plate can more firmly fix the connecting frame.

[0009] Furthermore, the connecting frame is bolted to the bearing seat, the threaded hole is formed on one side wall of the support frame, and the screw is threaded to the threaded hole.

[0010] By adopting the above technical solution, the connecting frame can firmly fix the bearing seat, and the threaded hole can make it easier for the screw to rotate and move within the support frame.

[0011] Furthermore, the screw is rotatably connected to the bearing seat, and the sliding grooves are all formed on one side wall of the first support plate and the second support plate.

[0012] By adopting the above technical solution, the bearing seat facilitates the rotation of the screw on the connecting frame, and avoids rotating the connecting frame together with the screw when rotating the screw.

[0013] Furthermore, the sliding groove is welded to the fixed column, and the sliding groove is slidably connected to the adjusting plate.

[0014] By adopting the above technical solution, the sliding groove can firmly fix the fixed column, and the sliding groove facilitates the adjustment plate to adjust the height on the support plate one and the support plate two.

[0015] Furthermore, the connecting grooves are symmetrically formed on the adjusting plates, and the connecting grooves are slidably connected to the fixed columns. A lifting ring is fixed at the center of the top of each adjusting plate.

[0016] By adopting the above technical solution, the connecting groove and the fixed column cooperate to limit the adjustment plate in the sliding groove and prevent the adjustment plate from disengaging from the sliding groove.

[0017] Furthermore, the adjusting plate is connected to the lifting eye bolt, and each of the first and second support plates has a T-slot at one end.

[0018] By adopting the above technical solution, the adjusting plate can more securely fix the lifting ring. The lifting ring can facilitate the workers to pull the adjusting plate to move, and can also facilitate the lifting of the first support plate and the second support plate.

[0019] Furthermore, a T-shaped block is fixed to the other end of each of the first and second support plates, and the T-shaped groove is slidably connected to the T-shaped block.

[0020] By adopting the above technical solution, the first support plate and the second support plate can more firmly fix the T-shaped block. The T-shaped groove cooperates with the T-shaped block, which makes it easier to splice multiple first support plates together and multiple second support plates together.

[0021] Furthermore, each of the first and second support plates is symmetrically fixed with a post at its bottom, and each of the first and second support plates is welded to the post.

[0022] By adopting the above technical solution, the first support plate and the second support plate can more firmly fix the insert post, and the insert post can be inserted into the trench, thereby improving the stability of the connection between the first support plate and the second support plate and the bottom of the trench.

[0023] The beneficial effects of this invention are as follows: 1. To address the issue that existing trench support structures require threaded connections between each load-bearing rod and connecting rod, making assembly more cumbersome and affecting the speed of adjusting the distance between support plates according to the trench width, this invention addresses this problem by symmetrically installing support frames and connecting frames on opposite side walls of support plate one and support plate two. When adjusting the distance between support plate one and support plate two according to the trench width, simply turning the screw drives the connecting frame to move support plate two away from support plate one, thus enabling rapid adjustment of the distance between support plate one and support plate two according to the trench width. 2. To address the limitations of existing trench support structures due to the fixed height of the existing guard plates, which makes it inconvenient to adjust the height according to the trench excavation depth, this invention addresses this issue by creating sliding grooves on the opposite sidewalls of guard plate one and guard plate two. Tightening the fixing bolts removes the limiting effect of the sliding grooves on the adjusting plate, allowing the lifting ring to be pulled to adjust the height of the adjusting plate on guard plate one and guard plate two according to the trench depth. Then, tightening the fixing bolts again secures the adjusted plate to guard plate one and guard plate two, thus enabling adjustment of guard plate one and guard plate two according to the trench depth and avoiding the limitations of existing trench support structures.

[0026] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-4 As shown, a trench support assembly structure includes a support plate 1 and a support plate 2. Support frames 3 and connecting frames 4 are symmetrically installed on opposite side walls of support plates 1 and 2. A bearing seat 5 is provided on the side wall of the connecting frame 4 facing the support frame 3. A threaded hole 6 is provided on one side wall of the support frame 3, and a screw 7 connects the threaded hole 6 and the bearing seat 5. Tightening the screw 7 facilitates the movement of the connecting frame 4 away from the support frame 3, thereby adjusting the distance between support plates 1 and 2 according to the trench width. Sliding grooves 8 are provided on opposite side walls of support plates 1 and 2. Each sliding groove 8 contains a bearing seat 5. A fixed column 9 is fixedly attached to the sliding groove 8, and an adjusting plate 10 is connected to it. The adjusting plate 10 has a connecting groove 11 corresponding to the fixed column 9. A fixing hole 12 is provided on one side wall of the adjusting plate 10. The fixing hole 12 is formed on one side wall of the adjusting plate 10. An adjusting hole 13 is provided in the sliding groove 8 corresponding to the fixing hole 12. The adjusting hole 13 is formed on one side wall of the sliding groove 8 corresponding to the fixing hole 12. A fixing bolt 14 is connected through the adjusting hole 13 in the fixing hole 12. The fixing bolt 14 is threaded through the fixing hole 12 and the adjusting hole 13. The fixing bolt 14 and the adjusting hole 13 can more easily fix the moving adjusting plate 10 back firmly in the sliding groove 8.

[0027] In this embodiment, support plate 1 is bolted to support frame 3, and support plate 2 is bolted to connecting frame 4. Both support frame 3 and connecting frame 4 are U-shaped structures. Support plate 1 can more firmly fix support frame 3, and support plate 2 can more firmly fix connecting frame 4.

[0028] In this embodiment, the connecting frame 4 is bolted to the bearing seat 5, the threaded hole 6 is formed on one side wall of the support frame 3, and the screw 7 is threaded to the threaded hole 6. The connecting frame 4 can firmly fix the bearing seat 5, and the threaded hole 6 can make it easier for the screw 7 to rotate and move within the support frame 3.

[0029] In this embodiment, the screw 7 is rotatably connected to the bearing seat 5, and the sliding groove 8 is formed on one side wall of the support plate 1 and the support plate 2. The bearing seat 5 facilitates the rotation of the screw 7 on the connecting frame 4, and avoids the connecting frame 4 from rotating together when the screw 7 is rotated.

[0030] In this embodiment, the sliding groove 8 is welded to the fixed column 9 and is slidably connected to the adjusting plate 10. The sliding groove 8 can firmly fix the fixed column 9 and facilitates the adjustment plate 10 to adjust the height on the support plate 1 and the support plate 2.

[0031] In this embodiment, the connecting groove 11 is symmetrically formed on the adjusting plate 10, and the connecting groove 11 is slidably connected to the fixing column 9. A lifting ring 15 is fixed at the center of the top of each adjusting plate 10. The connecting groove 11 and the fixing column 9 cooperate to limit the adjusting plate 10 in the sliding groove 8 and prevent the adjusting plate 10 from separating from the sliding groove 8.

[0032] In this embodiment, the adjusting plate 10 is bolted to the lifting ring 15. Each support plate 1 and support plate 2 has a T-slot 16 at one end. The adjusting plate 10 can more securely fix the lifting ring 15. The lifting ring 15 can facilitate the workers to pull the adjusting plate 10 to move, and can also facilitate the lifting of support plate 1 and support plate 2.

[0033] In this embodiment, each support plate 1 and support plate 2 has a T-shaped block 17 fixed at its other end. The T-shaped groove 16 is slidably connected to the T-shaped block 17, so that the support plate 1 and support plate 2 can more firmly fix the T-shaped block 17. The T-shaped groove 16 cooperates with the T-shaped block 17, which makes it easier to splice multiple support plates 1 together and multiple support plates 2 together.

[0034] In this embodiment, each support plate 1 and support plate 2 is symmetrically fixed with a post 18 at its bottom. Each support plate 1 and support plate 2 is welded to the post 18. The support plate 1 and support plate 2 can more firmly fix the post 18. The post 18 can be inserted into the trench, thereby improving the stability of the connection between the support plate 1 and support plate 2 and the bottom of the trench.

[0035] A method for using a trench support composite structure: First, the support frame 3 and connecting frame 4 are positioned at the heights of support plate 1 and support plate 2, respectively. The support frame 3 and connecting frame 4 are symmetrically arranged on opposite side walls of support plate 1 and support plate 2. When it is necessary to adjust the distance between support plate 1 and support plate 2 according to the trench width, simply turning the screw 7 will drive the connecting frame 4 to move support plate 2 away from support plate 1, thus enabling rapid adjustment of the distance between support plate 1 and support plate 2 according to the trench width. By opening sliding grooves 8 on the opposite sidewalls of support plate 1 and support plate 2, and turning the fixing bolt 14, the limiting effect of sliding grooves 8 on adjusting plate 10 can be removed. Then, the height of adjusting plate 10 on support plate 1 and support plate 2 can be adjusted by pulling the lifting ring 15 according to the trench depth. Afterwards, turning the fixing bolt 14 again fixes the adjusted plate 10 on support plate 1 and support plate 2. This allows for adjustment of support plate 1 and support plate 2 according to the trench depth, avoiding the limitations of the trench support combination structure in use.
