Technical Field
[0001] This utility model relates to the technical field of foundation pit protection devices, and in particular to a foundation pit protection device for steel structures in building construction. Background Technology
[0002] Steel structures, as an important construction material, are widely used in modern building engineering, providing strong load-bearing capacity and stability. Their use greatly enhances the safety and durability of buildings, while also enabling more efficient completion of various design requirements during construction. The ductility and strength of steel make it highly adaptable in building engineering, especially suitable for multi-story or high-rise buildings, effectively supporting heavy loads and exhibiting excellent seismic performance.
[0003] Excavation pit retaining structures typically consist of several parts, including a support system, retaining walls, and waterproofing and seepage prevention design elements. The support system primarily serves to prevent soil collapse and provide temporary support, while the retaining walls are responsible for maintaining soil stability and preventing soil displacement into the pit. Furthermore, the retaining structure must also possess waterproofing and drainage capabilities to prevent moisture from seeping into the pit, affecting construction progress, or causing structural damage.
[0004] Traditional foundation pit retaining structures require extensive manual labor and mechanical equipment for assembly and disassembly. Typically, retaining structures consist of multiple large or heavy materials with various connection methods, making disassembly and reinstallation time-consuming and labor-intensive. Furthermore, the disassembly of traditional retaining structures often demands precise techniques and procedures; any oversight can lead to damage or construction safety hazards, thus impacting construction progress and project costs. Therefore, the inconvenience of assembling and disassembling traditional foundation pit retaining structures results in low construction efficiency, increased costs, and extended construction periods. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a foundation pit support device for steel structures in building construction, which aims to solve the problems of inconvenient disassembly and assembly of traditional foundation pit support devices, which leads to low construction efficiency, increased costs, and extended construction periods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A foundation pit support device for a steel structure in building construction includes steel pipe piles, a truss fixedly connected to the side wall of the steel pipe piles, a clamping tube fixedly connected to one end of the truss, a plurality of clamping slots being provided inside the clamping tube, and an outer ring fixedly connected to the other end of the truss, with a fixing component provided inside the outer ring.
[0008] The fixing assembly includes an inner tube, which is fixedly connected inside the outer ring. A fixed shaft is fixedly connected inside the inner tube. Multiple slip rings are slidably connected to the outer wall of the fixed shaft. A rotating rod is rotatably connected to the side wall of each slip ring. A clamping plate is fixedly connected to one end of the rotating rod. The clamping plate is slidably connected inside the inner tube. Multiple springs are sleeved on the outer wall of the slip ring. One end of each spring is fixedly connected to the surface of the slip ring, and the other end of each spring is fixedly connected to the inside of the inner tube. A support assembly is provided at the bottom of the steel pipe pile.
[0009] Furthermore, the support assembly includes a lower side plate, which is fixedly connected to the side wall of the steel pipe pile.
[0010] Furthermore, an upper side plate is provided on the top of the lower side plate, and a turntable is fixedly connected to the lower surface of the upper side plate.
[0011] Furthermore, a second turntable is fixedly connected to the upper surface of the lower side plate, and a first connecting shaft is fixedly connected inside the second turntable.
[0012] Furthermore, a support plate is rotatably connected to the outer wall of the connecting shaft, and the top of the support plate is rotatably connected to the lower surface of the turntable.
[0013] Furthermore, a connecting shaft 2 is fixedly connected inside the turntable 1, and a rotating frame is rotatably connected to the outer wall of the connecting shaft 2.
[0014] Furthermore, the lower surface of the upper side plate is provided with multiple carding platforms, and each carding platform is fixedly connected to a carding shaft on its lower surface, the carding shaft being slidably connected inside the rotating frame.
[0015] Furthermore, a second spring is provided on the top of the card platform, with one end of the second spring fixedly connected to the upper surface of the card platform and the other end of the second spring fixedly connected to the lower surface of the upper side plate.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, the outer ring is first placed on the outer wall of the clamping pipe, at which point the inner pipe can enter the inside of the clamping pipe. Finally, when the clamping plate is displaced, the rotating rod will rotate and push multiple slip rings to slide on the outer wall of the fixed shaft. Then, the spring will reset the steel pipe piles, enabling convenient assembly and disassembly. This allows for rapid installation and disassembly, thereby improving the overall construction efficiency.
[0018] 2. In this utility model, by pushing the card platform upward, the card shaft slides out from inside the rotating frame. After the card platform and the rotating frame are unlocked, the rotating frame no longer restricts the rotation of the support plate. The top of the support plate rotates on the lower surface of the rotating platform, while the bottom rotates inside the second rotating platform. This allows the bottom support to change the support method according to the terrain and site requirements, so as to adapt to various housing construction needs and improve the applicability of this support.

Detailed Implementation
[0025] 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.
[0026] Reference Figures 1-3 An embodiment of this utility model is provided: a foundation pit protection device for a steel structure in house construction, including a steel pipe pile 1, a truss 2 fixedly connected to the side wall of the steel pipe pile 1, a clamping pipe 3 fixedly connected to one end of the truss 2, a plurality of clamping slots 4 opened inside the clamping pipe 3, and an outer ring 5 fixedly connected to the other end of the truss 2, with a fixing component provided inside the outer ring 5.
[0027] The fixing assembly includes an inner tube 6, which is fixedly connected inside the outer ring 5. A fixing shaft 7 is fixedly connected inside the inner tube 6. Multiple slip rings 8 are slidably connected to the outer wall of the fixing shaft 7. A rotating rod 9 is rotatably connected to the side wall of each slip ring 8. A clamping plate 10 is fixedly connected to one end of the rotating rod 9. The clamping plate 10 is slidably connected inside the inner tube 6. Multiple springs 11 are sleeved on the outer wall of the slip ring 8. One end of the spring 11 is fixedly connected to the surface of the slip ring 8, and the other end of the spring 11 is fixedly connected to the inside of the inner tube 6. A support assembly is provided at the bottom of the steel pipe pile 1.
[0028] Specifically, when multiple steel pipe piles 1 need to be connected, the outer ring 5 is placed on the outer wall of the clamping pipe 3, and the inner pipe 6 can then enter the clamping pipe 3. During this process, the clamping plate 10 will retract and enter the inner pipe 6 when passing through the clamping groove 4. Subsequently, through the elastic force of the spring 11, the clamping plate 10 will reset and re-enter the clamping groove 4. When the clamping plate 10 is displaced, the rotating rod 9 will drive multiple slip rings 8 to slide along the outer wall of the fixed shaft 7. The movement of the slip rings 8 is also subject to the reset action of the spring 11, ensuring that the connection process between the steel pipe piles 1 is simpler and the disassembly and assembly of the steel pipe piles 1 can be completed quickly. This significantly improves the efficiency of installation and disassembly during construction, reduces the construction period and labor requirements, makes the construction process more efficient, and improves the overall construction speed and accuracy.
[0029] Reference Figure 4 The support assembly includes a lower side plate 14, which is fixedly connected to the side wall of the steel pipe pile 1. An upper side plate 12 is provided on the top of the lower side plate 14. A turntable 13 is fixedly connected to the lower surface of the upper side plate 12. A turntable 25 is fixedly connected to the upper surface of the lower side plate 14. A connecting shaft 16 is fixedly connected inside the turntable 25. A support plate 17 is rotatably connected to the outer wall of the connecting shaft 16. The top of the support plate 17 is rotatably connected to the lower surface of the turntable 13. A connecting shaft 28 is fixedly connected inside the turntable 13. A rotating frame 19 is rotatably connected to the outer wall of the connecting shaft 28. Multiple clamping platforms 20 are provided on the lower surface of the upper side plate 12. A clamping shaft 21 is fixedly connected to the lower surface of each clamping platform 20. The clamping shaft 21 is slidably connected inside the rotating frame 19. A spring 22 is provided on the top of the clamping platform 20. One end of the spring 22 is fixedly connected to the upper surface of the clamping platform 20, and the other end of the spring 22 is fixedly connected to the lower surface of the upper side plate 12.
[0030] Specifically, the bottom of the steel pipe pile 1 is equipped with an additional three-dimensional support. By pushing the locking platform 20 upward, the locking shaft 21 can slide out from inside the rotating frame 19, thereby releasing the locking relationship between the locking platform 20 and the rotating frame 19. Once the locking platform 20 and the rotating frame 19 are unlocked, the rotating frame 19 no longer restricts the rotation of the support plate 17. The top of the support plate 17 can rotate on the lower surface of the first rotating platform 13, while the bottom of the support plate 17 can rotate inside the second rotating platform 15. The bottom support method of the support plate 17 can be adjusted and changed according to different terrains and actual site requirements, providing a more flexible support method. This allows the support system of the steel pipe pile 1 to adapt to different types of building construction needs, improves the applicability and operability of the support device, ensures stable and effective support of the structure under different working conditions, and meets the diverse requirements of the construction site.
[0031] Working principle: When multiple steel pipe piles 1 need to be connected, the outer ring 5 is fitted onto the outer wall of the clamping pipe 3, at which point the inner pipe 6 can enter the interior of the clamping pipe 3. When the clamping plate 10 passes through the clamping groove 4, it will retract into the interior of the inner pipe 6 and be reset into the clamping groove 4 by the elastic force of the spring 11. When the clamping plate 10 is displaced, the rotating rod 9 will rotate and push multiple sliding rings 8 to slide on the outer wall of the fixed shaft 7. Then, it will be reset by the spring 11. The steel pipe piles 1 can be easily assembled and disassembled, which can be quickly installed and disassembled, thereby improving the overall construction efficiency. The bottom of the steel pipe pile 1 is provided with additional three-dimensional support. Pushing the clamping platform 20 upward will cause the clamping shaft 21 to slide out from the inside of the rotating frame 19. After the clamping platform 20 is released from the locking of the rotating frame 19, the rotating frame 19 no longer restricts the rotation of the support plate 17. The top of the support plate 17 rotates on the lower surface of the rotating platform 13, while the bottom rotates inside the rotating platform 25. The bottom support can be changed according to the terrain and site requirements, which has adapted to various building construction needs and improved the applicability of this support.
[0032] 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.
