[0002] Steel support components are commonly used support components in building construction, especially in foundation pit support projects. They are used to withstand soil pressure and water pressure and transfer them to the support structure, thereby ensuring the safety and stability of the foundation pit.

[0003] Steel support assemblies in related technologies typically include a horizontally positioned support section with support seats at both ends, which are then fixed to the pit enclosure using fastening bolts. However, the angle between the support seats and the support section in these assemblies is not adjustable. For trapezoidal pits, where the pit enclosure is inclined, additional support seats need to be designed to match. Therefore, steel support assemblies in these technologies suffer from poor adaptability and require improvement. Utility Model Content

[0011] Optionally: Each of the limiting components includes two horizontally arranged limiting rods, and the limiting rods pass through the corresponding support cylinders and form a horizontal sliding fit with the corresponding support cylinders through sliding keys and sliding grooves. The ends of each limiting rod are coaxially fixedly connected to limiting toothed rollers, and the two ends of each rotating shaft are respectively provided with limiting toothed grooves for the corresponding limiting toothed rollers to insert and form engagement.

[0012] Optionally, a locking plate is fixedly connected to one end of each limiting rod away from the corresponding limiting toothed roller, and the locking plate is connected to the corresponding support cylinder by fastening screws.

[0013] Optionally, each of the locking plates is fixedly connected with a push-pull ring.

[0014] Optionally, the support portion includes multiple coaxially arranged steel cylinders, each steel cylinder having a flange at both ends, and the flanges of two adjacent steel cylinders being close to each other are connected by multiple locking bolts.

[0015] Optionally, each of the receiving seats is fixed with a connecting flange, and the connecting flange is connected to the flange on the corresponding steel support cylinder by a plurality of limiting bolts.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 , Figure 2 A steel support assembly includes a horizontally arranged support part 1, with support seats 2 at both ends of the support part 1. Each support seat 2 includes a receiving seat 21, a mounting seat 22, and a connecting seat 23. The receiving seat 21 is connected to the corresponding end of the support part 1, the mounting seat 22 is fixed to the corresponding receiving seat 21, and the connecting seat 23 is used to connect with the foundation pit enclosure.

[0024] Reference Figure 2 , Figure 3 Each connecting seat 23 is hinged to a corresponding mounting seat 22, and the angle between the connecting seat 23 and the vertical direction is adjustable so that the connecting seat 23 can cooperate with the inclined pit enclosure plate. At the same time, each mounting seat 22 is provided with a limiting member 3, which is used to restrict the rotation of the corresponding connecting seat 23.

[0025] When the steel support assembly is applied to a rectangular foundation pit, that is, when the foundation pit enclosure is vertical, rotate the connecting seat 23 and make the surface of the connecting seat 23 vertical. Then, lock the connecting seat 23 by the limiting member 3. Subsequently, the connecting seat 23 can be connected to the foundation pit enclosure by fastening bolts.

[0026] When the steel support assembly is applied to a trapezoidal pit, that is, when the pit enclosure is inclined, rotate the connecting seat 23 until the surface of the connecting seat 23 is flush with the pit enclosure. Then, lock the connecting seat 23 by the limiting member 3. Subsequently, the connecting seat 23 and the pit enclosure can be connected by fastening bolts.

[0027] Because the connecting seat 23 can rotate, it can be adapted to the vertically or inclined foundation pit enclosure, meaning that the steel support assembly can be used for rectangular and trapezoidal foundation pits, thereby improving the adaptability of the steel support assembly.

[0028] Reference Figure 2 , Figure 3 Each mounting base 22 is horizontally fixedly connected to two support cylinders 24, and each connecting base 23 is horizontally fixedly connected to a rotating shaft 25. The two ends of each rotating shaft 25 are inserted into the corresponding support cylinder 24 and are rotatably connected to the corresponding support cylinder 24 through bearings, so that the connecting base 23 can rotate smoothly.

[0029] Reference Figure 2 , Figure 3Each limiting member 3 includes two horizontally arranged limiting rods 31, which pass through the corresponding support cylinder 24 and form a horizontal sliding engagement with the corresponding support cylinder 24 through a sliding key and a sliding groove. The function of the sliding key and the sliding groove is to restrict the limiting rod 31 from rotating along its own axis, that is, the limiting rod 31 can slide horizontally. The end of each limiting rod 31 is coaxially fixedly connected to a limiting toothed roller 32, and each end of each rotating shaft 25 is provided with a limiting toothed groove 33 for the corresponding limiting toothed roller 32 to insert into and form a meshing.

[0030] Pulling the limiting rod 31 causes the limiting toothed roller 32 to move. When the limiting toothed roller 32 separates from the corresponding limiting toothed groove 33, the connecting seat 23 can be unlocked. Similarly, pushing the limiting rod 31 causes the limiting toothed roller 32 to move. When the limiting toothed roller 32 inserts into the limiting toothed groove 33 and meshes with it, the connecting seat 23 can be locked.

[0031] Reference Figure 2 , Figure 3 Each limiting rod 31 has a locking plate 4 fixedly connected to one end away from the corresponding limiting toothed roller 32. The locking plate 4 is connected to the corresponding support cylinder 24 by fastening screws 5. That is, after the limiting toothed roller 32 engages with the corresponding limiting toothed groove 33, the locking plate 4 can be fixed to the corresponding support cylinder 24 to fix the limiting rod 31 and prevent the limiting rod 31 from sliding, so as to ensure the locking stability of the connecting seat 23.

[0032] Reference Figure 2 , Figure 3 Each locking plate 4 is fixedly connected with a push-pull ring 6, which facilitates the push-pull operation of the locking plate 4 and the limit rod 31 by the staff, so that the connecting seat 23 can be quickly locked or unlocked, thereby improving the work efficiency.

[0033] Reference Figure 1 , Figure 2 The support unit 1 includes multiple coaxially arranged steel support cylinders 11, each with a flange 12 at both ends. The flanges 12 of two adjacent steel support cylinders 11 are connected by multiple locking bolts 13. The modular design of the support unit 1 facilitates handling and transportation by personnel, improving usability.

[0034] In this embodiment, the length of the support part 1 can be adjusted by increasing or decreasing the number of steel support cylinders 11, thereby enabling the steel support assembly to adapt to foundation pit support of different widths and further improving the adaptability of the steel support assembly.

[0035] Reference Figure 1 , Figure 2Each receiving seat 21 is fixed with a connecting flange 7, and the connecting flange 7 is connected to the flange 12 on the corresponding steel support cylinder 11 by multiple limit bolts, which further improves the modular design of the steel support assembly, thereby facilitating the transportation and other operations of the steel support assembly by the staff.
