Description

Technical Field

[0001] This utility model relates to the field of foundation pit support, specifically a foundation pit slope support structure that is easy to disassemble and store. Background Technology

[0002] Slope protection for foundation pits refers to a series of reinforcement measures taken in foundation pit engineering to ensure slope stability and prevent collapse or slippage during excavation. Due to the large depth of the foundation pit, slope stability is crucial for construction safety. Common types of foundation pit slope protection include sheet pile support, soil nailing wall support, anchor bolt support, shotcrete support, concrete retaining walls, and cofferdam support. Before construction begins, a detailed survey is required to understand the soil properties, hydrology, and other conditions, and a reasonable support scheme should be designed based on these conditions. Current support structures are generally large in size, making disassembly difficult. Furthermore, the disassembled support structures are relatively fragmented, occupying a large space during transportation and storage, which is inconvenient for recycling. This results in significant difficulties in recycling existing support structures and increases the economic cost of using them. Utility Model Content

[0003] The purpose of this utility model is to provide a foundation pit slope support structure that is easy to disassemble and store. It can solve the technical problems of the difficulty in disassembling and assembling existing support structures and the inconvenience of transportation and storage, reduce the difficulty of disassembling and assembling support structures, make the storage support structure occupy less space, improve the convenience of recycling and reuse, and reduce the use cost of support structures.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A foundation pit slope support structure that is easy to assemble, disassemble, and store includes a support base plate and support side plates. Multiple anchor rods are provided on both the support base plate and the support side plates. The support base plate is rotatably connected to one side of the support side plates. A storage groove is provided on the support base plate, and a sliding seat is slidably connected within the storage groove. A positioning post is provided between the sliding seat and the support base plate. A support rod is rotatably connected to the sliding seat, and the support rod can be rotatably hidden into the storage groove. A telescopic rod is slidably connected to the support rod, and a limiting post is provided between the telescopic rod and the support rod. A support groove is provided on the support side plates, and a support is rotatably connected within the support groove. The support can be rotatably hidden into the support groove, and the support is movably connected to the end of the telescopic rod.

[0006] Furthermore, a connecting screw is rotatably connected to the end of the telescopic rod, and a threaded sleeve is provided on the support, with the connecting screw threadedly connected to the threaded sleeve.

[0007] Furthermore, the connecting screw is equipped with a rotating knob.

[0008] Furthermore, the slide includes two symmetrically arranged slide plates, which are slidably connected to the side wall of the storage groove. The two sides of the support rod are rotatably connected to the two slide plates respectively, and the positioning post is disposed between the slide plates and the support base plate.

[0009] Furthermore, the support base plate is provided with multiple positioning holes on both sides of the storage groove, and the positioning pin passes through the positioning hole and is threadedly connected to the slide plate.

[0010] Furthermore, the support rod is provided with a telescopic groove, and the telescopic rod is slidably connected in the telescopic groove.

[0011] Furthermore, the limiting post is threadedly connected to the support rod, and the telescopic rod is provided with multiple limiting holes. The limiting post penetrates the side wall of the telescopic groove and is movably inserted into the limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model includes a support base plate and support side plates, both of which are provided with multiple anchor rods. The support base plate has a storage groove, in which a sliding seat is slidably connected. A positioning post is provided between the sliding seat and the support base plate, and a support rod is rotatably connected to the sliding seat. The support side plate has a support groove, in which a support is rotatably connected. A telescopic rod is slidably connected to the support rod, and a limiting post is provided between the telescopic rod and the support rod. The end of the telescopic rod is movably connected to the support. In use, this structure allows the support side plate to be rotated to open relative to the support base plate, allowing the support side plate to be aligned with the base plate. The slope of the pit is aligned with the support rod. The support rod in the storage slot and the support in the support slot are rotated out. The slide block is slid to the appropriate position and fixed with the positioning column. The telescopic rod on the support rod is slid outward and fixed with the limiting column, so that its end is connected to the support. Finally, the anchor rod is used to fix the support bottom plate and the support side plate, thereby achieving effective support and fixation of the support side plate after rotation. This greatly improves the relative structural strength between the support side plate and the support bottom plate, and can support slopes with different slopes, greatly improving the strength of the foundation pit slope support.

[0014] 2. The support rod can be rotated and hidden into the storage groove, and the support can be rotated and hidden into the support groove. When disassembling the support structure, the anchor rod is first removed, then the end of the telescopic rod is separated from the support, the restriction of the limiting column is released, the telescopic rod is slid to shorten its total length with the support rod, and then the slide block is slid to the end of the storage groove. After rotating the support rod, it is stored in the storage groove, and the support is rotated to be stored in the support groove. Then, the support side plate is rotated to fit against the support bottom plate, so that the stored support structure forms two mutually fitting plate-like structures. This greatly reduces the footprint of the stored support structure, greatly reduces the difficulty of disassembly and storage, facilitates transportation and storage, improves the convenience of recycling, and allows a set of support structures to be reused, greatly reducing the use cost of the support structure.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Reference Figure 1This utility model describes a foundation pit slope support structure that is easy to assemble, disassemble, and store. The main structure includes a support base plate 1 and support side plates 2. The support base plate 1 contacts the bottom of the foundation pit, and the support side plates 2 contact the slope of the foundation pit. Multiple anchor rods 3 are provided on both the support base plate 1 and the support side plates 2. The anchor rods 3 are used to fix the support base plate 1 and the support side plates 2 within the foundation pit. Any existing anchoring method can be used. The support base plate 1 and the support side plates 2 are rotatably connected on one side by a hinge or latch. This structure allows the support side plates 2 to be closed or opened relative to the support base plate 1 after rotation. Therefore, during use, the support side plates 2 can be opened to a specified angle to match different slope gradients, greatly improving the protection against various slopes. The adaptability of the slope support to the same slope is such that the combined support structure forms a double-layered plate structure that fits together, greatly reducing its footprint, facilitating storage and transportation, and significantly improving the convenience of recycling. The support base plate 1 is provided with a storage groove 4, which is recessed downwards from the top of the support base plate 1. A sliding block is slidably connected to the storage groove 4, and a positioning post 5 is provided between the sliding block and the support base plate 1. The positioning post 5 can fix the sliding position of the sliding block, improving the stability of the sliding block after sliding. A support rod 6 is rotatably connected to the sliding block via a pin or hinge. The support rod 6 can be rotated and hidden inside the storage groove 4. With this structure, when the support rod 6 is in use, the sliding block slides laterally to near the middle position of the storage groove 4. This design allows the support rod 6 to form a certain angle with the middle of the support base plate 1, improving the stability of the support structure. During storage, the sliding block slides laterally to the end of the storage slot 4, allowing the support rod 6 to be completely hidden inside the storage slot 4 after rotating relative to the sliding block. This ensures that when the support side plate 2 rotates and closes relative to the support base plate 1, the support rod 6 will not form a protrusion on the support base plate 1, making the structure more compact and further reducing space occupancy. A telescopic rod 7 is slidably connected to the support rod 6. The total length of the telescopic rod 7 and the support rod 6 changes after sliding. A limiting post 8 is provided between the telescopic rod 7 and the support rod 6 to fix the position of the telescopic rod 7 after sliding. The position of the telescopic rod 7 after sliding is more stable. The support side plate 2 is provided with a support groove 9, which is recessed inward from the surface of the support side plate 2. A support 10 is rotatably connected to the support groove 9 by a pin or hinge. The support 10 can be hidden in the support groove 9 by rotation. When the support side plate 2 is open for use, the support 10 is rotated out from the support groove 9. The support 10 is movably connected to the end of the telescopic rod 7. After connecting the end of the telescopic rod 7 to the support 10, a stable inclined support structure is formed between the support base plate 1 and the support side plate 2 by the cooperation of the support rod 6 and the telescopic rod 7. The telescopic rod 7 adjusts its relative position with the support rod 6 by sliding, so that the total length of the two meets the support requirements of slopes with different slopes.This significantly improves the stability and adaptability of the support structure. After disassembly, the telescopic rod 7 slides relative to the support rod 6, shortening their total length. The lateral sliding slide block reaches the end of the storage groove 4. Rotating the support rod 6 causes the entire structure of the support rod 6 and telescopic rod 7 to rotate into the storage groove 4. The support 10 rotates into the support groove 9. After the support side plate 2 rotates relative to the support base plate 1, the two plates can completely fit together, forming a double-layered plate structure after storage. This greatly reduces the difficulty of disassembly, and the structure occupies less space after disassembly and storage, significantly increasing the ease and difficulty of recycling. This allows a single support structure to be reused multiple times, greatly reducing the cost of using the support structure.

[0023] Preferred, refer to Figure 3 and Figure 4 The end of the telescopic rod 7 is rotatably connected to a connecting screw 11 via a bearing. A threaded sleeve 12 is fixed to the support 10 by welding or bolts. The connecting screw 11 and the threaded sleeve 12 are threadedly connected. With this structure, before the end of the telescopic rod 7 is connected to the support 10, the restriction of the limiting post 8 is released, allowing the telescopic rod 7 to slide freely relative to the support rod 6. Then, the connecting screw 11 at the end of the telescopic rod 7 is rotated to make it threadedly connected to the threaded sleeve 12. After that, the position of the telescopic rod 7 is fixed again by the limiting post 8, making the connection between the telescopic rod 7 and the support 10 faster, the connected structure more robust, and the subsequent disassembly more efficient and convenient.

[0024] Preferably, a rotating knob 13 is fixed to the connecting screw 11 by welding or bolting. The rotating knob 13 is polygonal or has multiple grooves on its edge to increase the friction when the operator rotates it. This makes it easier for the operator to rotate the connecting screw 11 by rotating the rotating knob 13, making the connection process between the telescopic rod 7 and the support 10 more convenient and labor-saving, and further reducing the difficulty of subsequent disassembly and assembly operations.

[0025] Preferred, refer to Figure 2 The slide includes two symmetrically arranged slide plates 14, which are slidably connected to the side wall of the storage groove 4. Specifically, the longitudinal section of the slide plate 14 is L-shaped, and the side wall of the storage groove 4 is provided with a groove. The transverse part of the L-shape is slidably connected in the groove, making the sliding structure of the slide plate 14 relative to the storage groove 4 more stable. The two sides of the support rod 6 are rotatably connected to the two slide plates 14 by pins or hinges. The positioning post 5 is set between the slide plate 14 and the support base plate 1. This structure makes the sliding structure of the slide relative to the storage groove 4 more stable, provides better rotational support for the support rod 6, and improves the robustness of the support structure.

[0026] Preferably, the support base plate 1 has multiple through positioning holes 15 located on both sides of the storage groove 4. The positioning pin 5 passes through the positioning hole 15 and is threadedly connected to the slide plate 14. With this structure, after the slide plate 14 is slid, the positioning pin 5 can be inserted into the corresponding positioning hole 15, so that the positioning pin 5 passes through the corresponding positioning hole 15 and is threadedly connected to the slide plate 14, thereby positioning the lateral sliding position of the slide plate 14, improving the positioning effect of the sliding structure of the slide block, and improving the convenience of the positioning operation.

[0027] Preferably, the support rod 6 is provided with a telescopic groove 16, which is recessed inward from one end of the support rod 6. The telescopic rod 7 passes through one end of the telescopic groove 16 and is slidably connected in the telescopic groove 16. This structure allows the telescopic rod 7 to slide into the telescopic groove 16 after sliding relative to the support rod 6, so that the telescopic rod 7 can be stored in the telescopic groove 16 after sliding. The resulting structure has a smaller overall footprint and can be better stored in the storage slot 4, further improving the convenience of storage.

[0028] Preferably, the limiting post 8 is threadedly connected to the support rod 6, and the telescopic rod 7 is provided with multiple limiting holes 17. The limiting holes 17 are recessed inward from the surface of the telescopic rod 7. The limiting post 8 penetrates the side wall of the telescopic groove 16 and is movably inserted into the limiting hole 17. With this structure, when the telescopic rod 7 is sliding, the limiting post 8 is rotated to separate it from the limiting hole 17, and the telescopic rod 7 can slide freely. After the telescopic rod 7 slides to the position relative to the support rod 6, the limiting post 8 is rotated in the opposite direction so that its end can rotate into the limiting hole 17, thereby effectively limiting the position of the telescopic rod 7 relative to the support rod 6. The limiting operation is more convenient and the limiting structure is more stable.

[0029] Working principle: The structure of this utility model includes a support base plate 1 and a support side plate 2, both of which are provided with multiple anchor rods 3. The support base plate 1 has a storage groove 4, and a sliding seat is slidably connected in the storage groove 4. A positioning post 5 is provided between the sliding seat and the support base plate 1. A support rod 6 is rotatably connected to the sliding seat. The support side plate 2 has a support groove 9, and a support 10 is rotatably connected in the support groove 9. A telescopic rod 7 is slidably connected to the support rod 6, and a limiting post 8 is provided between the telescopic rod 7 and the support rod 6. The end of the telescopic rod 7 is movably connected to the support 10. This structure... When using the support structure, rotate the support side plate 2 to open it relative to the support bottom plate 1, so that the support side plate 2 fits against the slope of the foundation pit. Rotate and remove the support rod 6 in the storage groove 4 and the support 10 in the support groove 9. Slide the slide block to the appropriate position and fix it with the positioning column 5. Slide and pull out the telescopic rod 7 on the support rod 6 and fix it with the limiting column 8, so that its end is connected to the support 10. Finally, use the anchor rod 3 to fix the support bottom plate 1 and the support side plate 2, thereby achieving effective support for the rotated support side plate 2. This design significantly improves the relative structural strength between the support side plate 2 and the support bottom plate 1, enabling support for slopes of varying gradients and greatly enhancing the stability of the foundation pit slope support. The support rod 6 can be rotated and concealed within the storage groove 4, and the support 10 can be rotated and concealed within the support groove 9. When disassembling the support structure, this design first removes the anchor rod 3, then separates the end of the telescopic rod 7 from the support 10, releases the restriction of the limiting column 8, slides the telescopic rod 7 to shorten its total length with the support rod 6, and then slides... The slide block is moved to the end of the storage groove 4. After rotating the support rod 6, it is stored in the storage groove 4. The support 10 is rotated to be stored in the support groove 9. Then, the support side plate 2 is rotated to fit with the support bottom plate 1, so that the stored support structure forms two mutually fitted plate-like structures. This greatly reduces the floor space occupied by the stored support structure, greatly reduces the difficulty of disassembly and storage, facilitates transportation and storage, improves the convenience of recycling, and allows a set of support structures to be reused, greatly reducing the cost of using the support structure.
