[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 The present invention provides a support device for foundation excavation in building construction, comprising: eight support plates 1 and two docking components 3, wherein the cross-section of the support plates 1 is rectangular.

[0033] Among them, the docking component 3 is located on the side of the support plate 1, and the adjustment component 4 is provided on the side of the two adjustment plates 306 that are close to each other.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The docking assembly 3 includes a connecting plate 301 with a cross-shaped cross section. Mounting holes 303 are provided at each of the four bends of the connecting plate 301. The side of the support plate 1 is fitted against the inner wall of the mounting holes 303. Several insert plates 302 are slidably inserted through one side of the connecting plate 301. Several insertion holes 305 are provided on one side of the support plate 1, and the insertion holes 305 are adapted to the dimensions of the insert plates 302. An adjusting plate 306 is fixedly connected to one side of the insert plates 302. The adjusting plate 306 has a cross-shaped cross section. A lead screw 307 is threaded through the side of the adjusting plate 306. One end of the lead screw 307 is rotatably connected to one side of the connecting plate 301. Several rotating plates 308 are fixedly connected to the arc surface of the lead screw 307, and the rotating plates 308 are evenly distributed on the arc surface of the lead screw 307. By setting the docking component 3, personnel can easily splice several support plates 1 together, enabling the support plates 1 to support tunnels of different widths and improving the flexibility of the support device. Several limiting rods 309 are slidably inserted through the side of the adjusting plate 306, with one end of each limiting rod 309 fixedly connected to one side of the connecting plate 301. When the lead screw 307 drives the adjusting plate 306 to move, the limiting rods 309 can guide and position the adjusting plate 306, thereby improving the stability of the adjusting plate 306 during movement. A guide block 310 is fixedly connected to the side of the insert plate 302 away from the adjusting plate 306; the guide block 310 has a tapered structure. Due to the small size of the guide block 310 fixed to one end of the insert plate 302, the insert plate 302 can be easily inserted into the insertion hole 305. A positioning hole 311 is provided on one side of the inner wall of the mounting hole 303, and a positioning plate 304 is slidably inserted into the inner wall of the positioning hole 311, with the positioning plate 304 fixedly connected to one side of the support plate 1. While the support plate 1 is placed into the inner wall of the mounting hole 303, the positioning plate 304 fixed on the support plate 1 is inserted into the positioning hole 311, which achieves the effect of enabling the support plate 1 to move quickly to the designated position.

[0035] In the embodiments of this utility model, please refer to Figure 5The adjusting assembly 4 includes an arched plate 41 and two connecting plates 44. The sides of the two connecting plates 44 that are far apart from each other are fixedly connected to the sides of the two adjusting plates 306 that are close to each other. A slide rail 42 is fixedly connected to the upper surface of the arched plate 41. Two sliders 43 are slidably connected to the inner wall of the slide rail 42. The lower surface of the sliders 43 is fixedly connected to the upper surface of the adjusting plates 306. A bolt 45 is fixedly connected to the upper surface of the sliders 43. An adjusting ring 46 is threadedly connected to the arc surface of the bolt 45. By setting the adjusting assembly 4, after the support plates 1 are spliced ​​using the docking assembly 3, the distance between the left and right sets of support plates 1 can be easily adjusted, thereby enabling the support plates 1 to support foundation pits of different lengths, thus further improving the applicability of the support device. A rubber pad 47 is fixedly connected to the lower surface of the adjusting ring 46. The diameter of the rubber pad 47 is larger than the diameter of the adjusting ring 46. The rubber pad 47 increases the friction of the adjusting ring 46 near the slide rail 42, thus allowing the adjusting ring 46 to abut against the slide rail 42 more firmly with the help of the rubber pad 47. Several protrusions 48 are fixedly connected to the lower surface of the arched plate 41, and the protrusions 48 are evenly distributed on the lower surface of the arched plate 41. When the arched plate 41 supports the slide rail 42, the protrusions 48 fixed to the arched plate 41 can be driven into the foundation, thus making the arched plate 41 more firmly supported.

[0036] The working principle of the support device for foundation excavation in building construction provided by this utility model is as follows: When it is necessary to splice several support plates 1, firstly, the support plates 1 to be spliced ​​are respectively placed into the mounting holes 303 on the connecting plate 301. After the side of the support plate 1 is in contact with the inner wall of the mounting hole 303, the rotating plate 308 is rotated to drive the lead screw 307 to rotate. The lead screw 307 drives the adjusting plate 306, so that the adjusting plate 306 drives several insert plates 302 to move synchronously. When the insert plate 302 is inserted into the insertion hole 305 on the support plate 1, the splicing of the support plate 1 is completed. When it is necessary to separate the support plate 1, firstly, the rotating plate 308 is used to rotate the lead screw 307 in the opposite direction. The lead screw 307 drives the adjusting plate 306, so that the adjusting plate 306 drives several insert plates 302 to move synchronously. Move the plate away from the socket 305. After the plate 302 separates from the socket 305, move the support plate 1 to separate it from the inner wall of the mounting hole 303. This completes the disassembly and separation of the support plate 1. When the screw 307 drives the adjusting plate 306 to move, the limiting rod 309 can guide and position the adjusting plate 306, thereby improving the stability of the adjusting plate 306 during movement. In addition, since the guide block 310 fixed at one end of the plate 302 is small, it is easy to insert the plate 302 into the socket 305. Finally, while placing the support plate 1 into the inner wall of the mounting hole 303, insert the positioning plate 304 fixed on the support plate 1 into the positioning hole 311, so that the support plate 1 can be quickly moved to the designated position.

[0037] When the distance between the two adjusting plates 306 needs to be adjusted, first rotate the adjusting ring 46 to separate the rubber pad 47 from the upper surface of the slide rail 42, releasing the lock on the slider 43. Then move the adjusting plate 306 to drive the connecting plate 44, which in turn drives the slider 43 to slide along the inner wall of the slide rail 42. Once the distance between the two adjusting plates 306 is properly adjusted, rotate the adjusting ring 46 again to make the rubber pad 47 abut against the slide rail 42, locking the slider 43. The rubber pad 47 can increase the friction of the adjusting ring 46 on the side near the slide rail 42, making the adjusting ring 46 abut against the slide rail 42 more firmly with the help of the rubber pad 47. In addition, when the arched plate 41 supports the slide rail 42, the protrusions 48 fixed on the arched plate 41 can be driven into the foundation, making the arched plate 41 more firmly supported.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
