[0001] This utility model relates to the field of reinforced concrete construction technology, and in particular to a foundation pit support device for reinforced concrete construction. Background Technology

[0002] Foundation pit support refers to the general term for temporary support, protection and reinforcement measures taken during the excavation of foundation pits in construction projects to ensure the safety and stability of the foundation pit and its surrounding environment.

[0003] A search revealed Chinese patent CN111119200A, which discloses a foundation pit support device for supporting a foundation pit to be excavated. The device includes: multiple vertical support bodies for vertical insertion into the strata surrounding the foundation pit, arranged sequentially to form a closed loop; a waterproof structure between adjacent vertical support bodies; an internal support structure within each vertical support body; and adjacent support structures between adjacent vertical support bodies, the latter being integrated with the internal support structure. The foundation pit support device provided by this application can support the foundation pit with good construction quality, high support strength, strong resistance to deformation, and good waterproofing effect.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] The aforementioned patent structure is fixed and cannot be adjusted as needed, lacking flexibility. Furthermore, the fixed area occupied by the device may lead to a waste of land resources and a reduction in construction efficiency. If additional demolition and reconstruction work is required, it will increase project costs, thus presenting certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a foundation pit support device for reinforced concrete construction, which can be flexibly adjusted according to changes in subsequent construction or project needs, avoiding waste of land resources and improving construction efficiency.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a foundation pit support device for reinforced concrete construction, including a support plate, a support plate fixedly installed on one side of the bottom of the support plate, a fixing box fixedly installed in the middle of the support plate and one side of the support plate, a screw rod movably connected to the top of the fixing box through a bearing, a threaded sleeve connected to the surface of the screw rod, transmission rods fixedly installed on both sides of the threaded sleeve, through slots opened on both sides of the fixing box, a pair of support frames fixedly installed between the two sides of the support plate and the support plate, and a pair of horizontal plates fixedly installed on the side of the support plate near the bottom.

[0008] Preferably, a limiting groove is provided on one side of the inside of the fixing box, a limiting slider is fixedly installed on one side of the screw sleeve, and one end of the limiting slider is slidably connected inside the limiting groove.

[0009] Preferably, the transmission rod is fixedly connected to a connecting rod through the through groove, and an extension plate is fixedly installed at the other end of the connecting rod, the extension plate being inserted into the inside of the support plate.

[0010] Preferably, a partition is fixedly installed at the bottom of the fixed box, and a servo motor is fixedly installed at the bottom of the partition. The output end of the servo motor is fixedly connected to the bottom of the screw.

[0011] Preferably, each of the horizontal plates has a threaded rod connected to its surface via a screw hole, a handwheel is fixedly installed on the top of the threaded rod, and a pair of guide grooves are provided on the surface of the support plate, with the bottom of the threaded rod inserted into the guide groove.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model can flexibly respond to changes in engineering needs and maximize the utilization of underground space. Without changing the footprint of the foundation pit, it can increase the usable depth or net height of the foundation pit, thereby meeting the project's higher-level needs for underground space. This not only improves construction efficiency but also provides greater flexibility and expandability for the project's later functional layout and use.

[0014] Secondly, this utility model limits and guides the transmission rod by setting a through groove, and guides the threaded rod by using a horizontal plate and a guide groove. The threaded rod can improve the stability of the connection between the whole and the ground, and further improve the support effect of the support plate.

[0015] The existing structure is fixed, cannot be adjusted as needed, lacks flexibility, and occupies a fixed area, which may lead to waste of land resources and reduced construction efficiency. If additional demolition and reconstruction work is required, it will increase the project cost. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved foundation pit support device for reinforced concrete construction. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a foundation pit support device for reinforced concrete construction includes a support plate 1. A support plate 2 is fixedly installed on one side of the bottom of the support plate 1. A fixing box 3 is fixedly installed in the middle of the support plate 2 and on one side of the support plate 1. A screw rod 13 is movably connected to the top of the fixing box 3 through a bearing. A threaded sleeve 14 is threadedly connected to the surface of the screw rod 13. Transmission rods 17 are fixedly installed on both sides of the threaded sleeve 14. Through slots 11 are opened on both sides of the fixing box 3. A pair of support frames 9 are fixedly installed between the two sides of the support plate 2 and the support plate 1. A pair of horizontal plates 5 are fixedly installed on the side of the support plate 1 near the bottom. The support frames 9 can further improve the support effect of the support plate 1, form a triangular support, and improve the stability of the device.

[0026] Furthermore, a limiting groove 15 is provided on one side of the inside of the fixing box 3, and a limiting slider 16 is fixedly installed on one side of the screw sleeve 14. One end of the limiting slider 16 is slidably connected inside the limiting groove 15. By setting the limiting groove 15 and the limiting slider 16, the stability of the screw sleeve 14 during the up and down movement can be effectively improved.

[0027] Furthermore, the transmission rod 17 is fixedly connected to the connecting rod 10 through the through groove 11, and the other end of the connecting rod 10 is fixedly installed with an extension plate 4. The extension plate 4 is inserted into the inside of the support plate 1, which can increase the usable depth or clear height of the foundation pit, thereby meeting the project's higher-level needs for underground space.

[0028] As a further embodiment of this utility model, a partition 18 is fixedly installed at the bottom of the inner side of the fixed box 3, and a servo motor 12 is fixedly installed at the bottom of the partition 18. The output end of the servo motor 12 is fixedly connected to the bottom of the screw 13. The servo motor 12 is used to push the extension plate 4 out of the support plate 1, and the extension height of the extension plate 4 can be adjusted according to the construction requirements. This can flexibly respond to changes in engineering requirements and maximize the utilization of underground space.

[0029] Furthermore, each horizontal plate 5 has a threaded rod 7 connected to its surface via a screw hole. A handwheel 6 is fixedly installed on the top of the threaded rod 7. A pair of guide grooves 8 are opened on the surface of the support plate 1. The bottom of the threaded rod 7 is inserted into the guide groove 8. The threaded rod 7 can improve the stability of the connection between the device and the ground and ensure the safety of construction.

[0030] The specific working method is as follows: First, the entire structure is erected. Then, the handwheel 6 is turned, which drives the threaded rod 7 to rotate, thus fixing the entire structure into the soil. When it is necessary to adjust the height of the support plate 1 upward, the output end of the servo motor 12 drives the screw 13 to rotate. During the rotation, the screw 13 uses the thread to drive the threaded sleeve 14 to move upward. The threaded sleeve 14 drives the transmission rod 17 to move upward. The transmission rod 17 drives the extension plate 4 to move upward through the connecting rod 10, pushing the extension plate 4 out of the inner cavity of the support plate 1. The extension height of the extension plate 4 can be adjusted according to the construction requirements, which can flexibly respond to changes in engineering needs, maximize the utilization of underground space, and meet the project's higher-level needs for underground space.
