Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a prefabricated steel support structure for foundation pit engineering. Background Technology

[0002] Foundation pit support structures are key engineering facilities that ensure safety and stability during foundation pit excavation. With the increasing number of high-rise buildings in cities and the growing demand for underground space development, the scale and depth of foundation pit projects are gradually increasing. Therefore, traditional support methods (such as steel pipes and concrete supports) face problems such as large workload, long construction period, and difficulty in on-site management, and there is an urgent need for more efficient, safe, and fast support structures.

[0003] Prefabricated steel support structures are made of steel and consist of steel pipes, steel beams, and connectors. They are mainly used for supporting buildings, bridges, and other engineering projects. Their working principle is to bear and transfer loads through the support structure, providing stiffness and stability, distributing loads, and enhancing seismic resistance. The advantages of this structure include short construction period, structural stability, disassembly, and strong adaptability. It is widely used in high-rise buildings and temporary buildings.

[0004] Traditional methods for adjusting prefabricated steel support structures require adjusting each support component individually on-site. This is especially time-consuming when dealing with complex pit shapes or irregular structures. Therefore, a prefabricated steel support structure for pit engineering is proposed to solve the above problems. Utility Model Content

A connecting rod is threadedly connected to the outer wall of the screw. The outer wall of the screw is threadedly connected to the inner wall of the connecting shell. A mounting column is slidably connected to the inner wall of the slider.

[0008] As a further description of the above technical solution:

[0009] The detachable component includes a fixed base, the inner wall of which is threaded with four bolts, a connector is fixedly connected to the top of the fixed base, and the inner wall of the connector is slidably connected with two limiting plates. A spring is fixedly connected to the adjacent side of the two limiting plates, and a clamp is fixedly connected to one side of the limiting plate.

[0010] As a further description of the above technical solution:

[0011] A limit block is fixedly connected to the top of the mounting column, and two fixing blocks are fixedly connected to the outer wall of the slider.

[0012] As a further description of the above technical solution:

[0013] Each of the two fixing blocks has a mounting plate fixedly connected to one side, and the outer wall of the mounting column has a sliding groove.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the bolt is threaded to the inner wall of the fixed base plate, and the inner wall of the threaded rod is provided with a threaded groove.

[0016] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] The mounting column is made of steel, and the inner wall of the mounting plate has multiple mounting holes.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the connecting seat and the fixed base plate can be installed and fixed by bolts, so that the rotating block and the connecting shell can drive the threaded rod to rotate on the outer wall of the connecting seat, thereby adjusting the angle between the threaded rod and the connecting rod. The threaded rod and the connecting shell can be locked by screws. By rotating the two threaded rods, the threaded rod can be extended from the inner wall of the connecting rod, thereby adjusting the length of the threaded rod, thereby adjusting the height of the slider on the mounting column. The external mounting materials and the device can be connected and fixed by the mounting plate.

[0024] 2. In this utility model, when the mounting column is installed, by inserting the mounting column into the connector, the inner wall of the mounting column presses against the two clamps, causing the two limiting plates to move inward to compress the spring. When the clamps move into the groove of the mounting column, the elastic force generated by the spring compression can push the limiting plates and clamps to move outward, thereby locking the clamps onto the mounting column.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a prefabricated steel support structure for foundation pit engineering, including a fixed base plate 1. The fixed base plate 1 is the basic component of the entire structure, and its function is to ensure that the entire support can be stably fixed on the ground or in the foundation pit, preventing the support from being displaced or tilted due to external forces. The top of the fixed base plate 1 is provided with a detachable component, and the outer wall of the detachable component is slidably connected with a slider 10. The slider 10 plays the role of connection and adjustment, and can adjust the position of the support according to actual needs. Through the sliding connection, the support can adapt to different construction conditions, adjust the position of the support, and ensure stability. The outer wall of the slider 10 is fixedly connected with two fixing blocks 9. The two fixing blocks 9 serve as a connecting part, providing stronger connection and stability for the entire support. The inner walls of the two fixing blocks 9 are threaded with two bolts 2. The setting of the two bolts 2 connecting parts further enhances the tightness and stability between the various parts of the support. The threaded connection provides an adjustable function, which can precisely control the tightness of the connection.

[0034] Two bolts 2 are threadedly connected to a connecting seat 3 on their outer walls. The connecting seat 3 acts as a bridge connecting multiple components, making the entire support structure more compact and stable. A rotating block 4 is rotatably connected to the outer wall of the connecting seat 3, providing greater flexibility and allowing the support to rotate or adjust its angle within a certain range. A connecting shell 5 is fixedly connected to one side of the rotating block 4, serving as a guide and fixation mechanism for the rotating block 4, enhancing structural stability. A threaded rod 7 is slidably connected to the inner wall of the connecting shell 5. The threaded rod 7 allows for fine-tuning or precise positioning of subsequent components, increasing the adjustment accuracy of the device. It can be adjusted according to different support requirements, ensuring a uniform distribution of support force. The inner wall of the threaded rod 7 is threadedly connected to... Screw 6 acts as a lock, ensuring that the threaded rod 7 is securely fixed in the connecting shell 5, preventing loosening during use and ensuring the reliability and safety of the support device. The outer wall of screw 6 is threadedly connected to connecting rod 8. The threaded connection between connecting rod 8 and the two threaded rods 7 further enhances the stability of the overall structure. Connecting rod 8 also plays a key supporting role. The outer wall of screw 6 is threadedly connected to the inner wall of connecting shell 5. The inner wall of slider 10 is slidably connected to mounting post 11. The setting of mounting post 11 ensures the stability and reliability of the internal structure of the support body, provides support and fixation, so that the overall structure can be kept in a stable state, while allowing appropriate movement and adjustment between components.

[0035] Reference Figure 1 , Figure 3 and Figure 5The detachable component includes a mounting base 15, which is the basic component of the entire structure and provides support for fixing subsequent components. The inner wall of the mounting base 15 is threaded with four bolts 16. The fastening action of the bolts 16 ensures a stable connection between the mounting base 15 and the subsequent components, allowing the components to be installed securely. The top of the mounting base 15 is fixedly connected to a connector 17, which can slide on the inner wall of the mounting column 11, serving as a guide and limiter. The inner wall of the connector 17 is slidably connected to two limit plates 18, which can drive the subsequent components to move. The adjacent sides of the two limit plates 18 are fixedly connected to springs 19, providing elastic support. When the limit plates 18 move, the springs 19 provide restoring force to prevent the components from moving excessively or being damaged.

[0036] A locking head 20 is fixedly connected to one side of the limiting plate 18. The locking head 20 is fixedly connected to one side of the limiting plate 18 and is used to lock or fix the mounting column 11 to ensure the stability of the device and prevent loosening or falling off. A limiting block 12 is fixedly connected to the top of the mounting column 11. The limiting block 12 is part of the limiting function to ensure that the slider 10 will not exceed the predetermined track or position, thus ensuring the accuracy and safety of the device. Two fixing blocks 13 are fixedly connected to the outer wall of the slider 10. The fixing blocks 13 serve as supporting components for the slider 10, ensuring that the slider 10 runs stably during operation and will not deviate. A mounting plate 14 is fixedly connected to one side of each of the two fixing blocks 13. The mounting plate 14 provides a platform for fixing external connecting components and enhances the stability of the structure.

[0037] Working principle: The connecting seat 3 and the fixed base plate 1 can be installed and fixed by bolt 2, so that the rotating block 4 and the connecting shell 5 can drive the threaded rod 7 to rotate on the outer wall of the connecting seat 3, thereby adjusting the angle of the device. The threaded rod 7 and the connecting shell 5 can be locked by screw 6. By rotating the two threaded rods 7, the threaded rod 7 can be extended from the inner wall of the connecting rod 8, thereby adjusting the length of the threaded rod 7, and thus adjusting the height of the slider 10 on the mounting column 11. The external mounting material can be connected and fixed to the device by the mounting plate 14.

[0038] By pressing the two locking heads 20 inward, the two locking heads 20 can drive the limiting plate 18 to move inward. At this time, the mounting post 11 can be removed from the connector 17, releasing the locking heads 20 from locking the mounting post 11. The connector 17 is inserted into the inner wall of the mounting post 11 to prevent the mounting post 11 from shifting during use. When the mounting post 11 is installed, by inserting the mounting post 11 into the connector 17, the inner wall of the mounting post 11 squeezes the two locking heads 20, causing the two limiting plates 18 to move inward and squeeze the spring 19. When the locking heads 20 move into the groove of the mounting post 11, the elastic force generated by the spring 19 can push the limiting plate 18 and the locking heads 20 to move outward, thus locking the locking heads 20 onto the mounting post 11.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
