[0002] The purpose of foundation pit support is to reinforce and protect the sidewalls of the foundation pit and its surrounding environment. Currently, the most common method for foundation pit support is using vertical piles, support columns, and a top slab. This involves driving vertical piles into the sidewalls of the foundation pit, fixing a top slab to the piles, and then placing support columns between the top slabs. This support method requires selecting the appropriate materials for the vertical piles, support columns, and top slab based on the size of the foundation pit, which is relatively inconvenient.

[0003] The utility model patent with publication number CN211922639U provides a foundation pit support device, in which a retractable support column is set between the H-shaped top steel. The support column includes an inner column and an outer column, and the inner column and the outer column can slide together, thereby realizing the extension and retraction of the support column, so that the foundation pit support device can realize the support of foundation pits of any width.

[0004] Although the aforementioned foundation pit support device can adjust the length of the support columns according to the size of the foundation pit, the support columns of the aforementioned foundation pit support device are set in a straight line. Therefore, the aforementioned foundation pit support device can only support the foundation pit sidewalls that are in the same plane. If the foundation pit sidewalls are not in the same plane and there is a certain angle between the sidewalls, the aforementioned foundation pit support device cannot be used for support, resulting in low practicality.

[0021] This utility model provides a foundation pit support device, including two H-shaped top steels 100 and a support assembly. The support assembly includes two support columns and an angle adjustment structure. The angle adjustment structure includes a first adjustment plate 210, a second adjustment plate 220, a connecting column cylinder 230, a connecting threaded column 240, and a connecting seat 250. The support column includes a supporting outer cylinder 310, a supporting inner cylinder 320, a connecting cylinder 330, and a connecting structure. The connecting structure includes a U-shaped plate 341 and an adjusting threaded column 342.

[0022] In this specific embodiment, the two ends of the support assembly are detachably connected to the two H-shaped top steels 100, the support assembly is disposed between the two H-shaped top steels 100, the angle adjustment structure is disposed between the two support columns, and the end of the support column away from the angle adjustment structure is detachably connected to the H-shaped top steel 100; the first adjustment plate 210 and the second adjustment plate 220 are rotatably connected, the first adjustment plate 210 is hinged to one of the support columns, the second adjustment plate 220 is hinged to the other support column, the connecting column cylinder 230 is hinged to the first adjustment plate 210, the connecting seat 250 is hinged to the second adjustment plate 220, one end of the connecting threaded column 240 is rotatably connected to the connecting seat 250, and the other end of the connecting threaded column 240 is threadedly connected to the connecting column cylinder 230, and both the first adjustment plate 210 and the second adjustment plate 220 are provided with fixing holes 211. The H-shaped top steel 100 is used to fix the pit sidewall. The support assembly is arranged between two H-shaped top steels 100 to support the pit sidewall between the two H-shaped top steels 100. The angle adjustment structure is used to adjust the angle between the two support columns, so that the angle of the two support columns can be adjusted. The first adjustment plate 210 and the second adjustment plate 220 are rotated by hinges. The connecting column cylinder 230, the connecting threaded column 240, and the connecting seat 250 are arranged between the first adjustment plate 210 and the second adjustment plate 220. The connecting column cylinder 230, the connecting threaded column 240, and the connecting seat 250 connect the first adjustment plate 210 and the second adjustment plate 220. The connecting cylinder 230 has a threaded groove adapted to the connecting threaded post 240. The connecting seat 250 is hinged to the second adjusting plate 220 and connected to the connecting threaded post 240. The connecting threaded post 240 can rotate relative to the connecting seat 250 and can rotate into the threaded groove of the connecting cylinder 230. When the connecting threaded post 240 rotates, the length of the connecting threaded post 240 in the connecting cylinder 230 will change, thereby changing the overall length of the connecting cylinder 230 and the connecting threaded post 240. When the overall length of the connecting cylinder 230 and the connecting threaded post 240 changes, it will drive the first adjusting plate 210 and the second adjusting plate 220 to rotate, thereby adjusting the angle of the first adjusting plate 210 and the second adjusting plate 220.When it is necessary to support the sidewalls of a foundation pit that are not on the same plane, the angle adjustment structure is first placed at the junction of the two sidewalls. The length of the connecting threaded column 240 in the connecting column cylinder 230 is adjusted by turning the connecting threaded column 240, thereby adjusting the angles of the first adjusting plate 210 and the second adjusting plate 220 so that the angles of the first adjusting plate 210 and the second adjusting plate 220 adapt to the angles of the two sidewalls, so that the two support columns can be attached to the two sidewalls respectively. Then, the lengths of the two support columns are adjusted so that the two H-shaped top steels 100 are located at both ends of the foundation pit sidewall. Finally, the two H-shaped top steels 100 are fixed, thereby supporting the foundation pit sidewalls that are not on the same plane and improving practicality.

[0023] Specifically, the angle adjustment structure further includes an adjustment bracket 260, which is fixedly connected to the connecting threaded post 240. The adjustment bracket 260 is located at the end of the connecting threaded post 240 away from the connecting cylinder 230. The adjustment bracket 260 is provided on the outside of the connecting threaded post 240 so that relevant personnel can rotate the connecting threaded post 240 through the adjustment bracket 260.

[0024] In this configuration, one end of the outer support cylinder 310 of each of the two support columns is hinged to the first adjusting plate 210 and the second adjusting plate 220, respectively. One end of the inner support cylinder 320 is threadedly connected to the outer support cylinder 310. A connecting cylinder 330 is rotatably connected to the inner support cylinder 320 and is located at the end of the inner support cylinder 320 away from the outer support cylinder 310. The connecting structure is disposed between the H-shaped top steel 100 and the connecting cylinder 330. The connecting structure is used to connect the connecting cylinder 330 and the H-shaped top steel 100. The outer support cylinder 310 has an internal thread, and the inner support cylinder 320 has an external thread adapted to the internal thread. When the inner support cylinder 320 rotates, its length within the outer support cylinder 310 changes, thereby changing the length of the entire support column to achieve length adjustment of the support column.

[0025] Secondly, the connecting cylinder 330 is hinged to the U-shaped plate 341, which is sleeved on the H-shaped top steel 100. The adjusting threaded post 342 is threadedly connected to the U-shaped plate 341. The U-shaped plate 341 is used to sleeve on the H-shaped top steel 100, and the adjusting threaded post 342 can be screwed on the U-shaped plate 341. When the adjusting threaded post 342 is tightened, it extends out of the U-shaped plate 341 and, with the cooperation of the U-shaped plate 341, holds the U-shaped plate 341 onto the H-shaped top steel 100, thereby fixing the U-shaped plate 341 to the H-shaped top steel 100. When disassembly is required, the adjusting threaded post 342 can be directly removed from the U-shaped plate 341, thus removing the U-shaped plate 341 from the H-shaped top steel 100.

[0026] Furthermore, the foundation pit support device also includes multiple auxiliary support rods 400, with the auxiliary support rods 400 threadedly connected to both the upper and lower ends of the first adjusting plate 210 and the second adjusting plate 220. The auxiliary support rods 400 are threadedly connected to the first adjusting plate 210 and the second adjusting plate 220, and can provide support for the remaining positions of the foundation pit sidewall, thereby improving the support effect on the foundation pit sidewall.

[0027] When using this foundation pit support device to support foundation pit sidewalls that are not on the same plane, first place the angle adjustment structure at the junction of the two sidewalls. Adjust the length of the connecting threaded post 240 within the connecting post cylinder 230 by turning the threaded post 240, thereby adjusting the angles of the first adjusting plate 210 and the second adjusting plate 220. This ensures that the angles of the first adjusting plate 210 and the second adjusting plate 220 adapt to the angles of the two sidewalls, allowing the two support columns to fit against the two sidewalls respectively. Then, turn the inner support cylinder 320 to adjust... The length of the support column is adjusted according to the length of the two side walls so that the two H-shaped top steels 100 are respectively located at both ends of the pit side wall. The adjusting threaded column 342 is tightened so that the adjusting threaded column 342 cooperates with the U-shaped plate 341 to hold the U-shaped plate 341 on the H-shaped top steel 100, thereby fixing the support assembly between the two H-shaped top steels 100. Finally, the two H-shaped top steels 100 are fixed, thereby supporting the pit side wall where the side walls are not on the same plane, improving practicality.
