The support rod is limitedly installed in the limiting groove through the limiting blocks, and a rotating block is rotatably installed on the end of the support rod away from the limiting block. A first connecting rod is welded on the outer surface of the rotating block, and the retaining plate is located above the support plate and is plugged with a second connecting rod. The limiting plate is movably installed on the second connecting rod, and a nut is threadedly connected to the second connecting rod on the side of the limiting plate away from the retaining plate.

[0003] The prior art forms a triangular support point through a support rod and a second connecting rod. Although it is suitable for conventional soil layers, and the bottom of the support plate is provided with a pointed cone to improve the stability of the support plate in the foundation pit, the support plate of the prior art can only fit the soil layer in the foundation pit, and when the current soil layer is relatively loose, the prior art cannot play a role in fixing the soil layer, thereby reducing the efficiency of foundation pit construction.

[0004] For this purpose, we designed a support plate for foundation pit. Utility Model Content

DETAILED DESCRIPTION

[0021] Reference Figure 1-Figure 4 A support plate for a foundation pit includes a plate body 1. The plate body 1 is a supporting formwork in the prior art, which is mainly used for supporting and protecting the soil layer in the foundation pit to prevent the soil layer from collapsing and causing the foundation pit to be unable to operate. The limiting rod 2 is a basic component on the plate body 1, and the fixed components can be evenly arranged in the limiting rod 2. At the same time, the length of the limiting rod 2 can avoid external influences on the fixed components. The support rod 4 is a prior art and is a commonly used supporting component for the foundation pit support formwork in the construction site. It can play a role of auxiliary support through the triangular support force. The bonding plate 10 is a prior art and can improve the contact effect between the plate body 1 and the soil layer.

[0022] A first fixing ring 3 for adjusting the angle of the support rod 4 is provided on the plate body 1. The first fixing ring 3 is used to fix the support rod 4 and improve the stability of the support rod 4 when supporting the plate body 1. The wall cabinet improves the supporting strength between one end of the support rod 4 and the soil layer. The first fixing ring 3 is fixedly connected to the plate body 1 by welding. The welding can improve the connection strength between the plate body 1 and the first fixing ring 3 to avoid external factors affecting the connection relationship between the two, and indirectly improve the supporting strength of the support rod 4. The first fixing ring 3 is fixed to the support rod 4 by fasteners. The fasteners are detachable fixing components, which are convenient for the later replacement and maintenance of the support rod 4.

[0023] A first threaded drill 8 for improving the connection between the plate body 1 and the soil layer is provided on the plate body 1. The first threaded drill 8 is provided at the upper end of the plate body 1, and is mainly used to fix the upper part of the plate body 1 to the soil layer, so that the upper part of the plate body 1 and the soil layer can obtain a higher contact and fixing effect. A first hexagonal nut 5 is provided on the first fixing ring 3. The first hexagonal nut 5 is a prior art. By fixing it on the first fixing ring 3, workers can change the current torque and the depth of the first threaded drill 8 in the soil layer by rotating it with a torque wrench. The first hexagonal nut 5 is fixedly connected to the first threaded drill 8 through a fastener. The fastener is an auxiliary connecting member, which is mainly used for the fixed connection between the two. A first threaded wire ring 11 for increasing the contact area of ​​the soil layer is provided on one side of the plate body 1. The first threaded wire ring 11 is fixed to the back side of the plate body 1 and wraps the first threaded drill 8 at the same time. When the first hexagonal nut 5 rotates, it will drive the first threaded wire ring 11 to rotate at the same time and embed into the soil layer.

[0024] The plate body 1 is provided with a plurality of second threaded drills 9 for improving the fit between the plate body 1 and the soil layer. The second threaded drills 9 are arranged at the bottom of the plate body 1 and are mainly used to fix the bottom of the plate body 1 and the soil layer. Since the bottom of the plate body 1 is the main fixing part, a total of three second threaded drills 9 are provided, which can effectively improve the stability. The second threaded drills 9 are rotatably connected to the plate body 1 through the second hexagonal nut 7. The second hexagonal nut 7 is a prior art. The torque is changed by a torque wrench. When the torque is changed, the depth of the second threaded drill 9 in the soil layer will also be changed. One side of the plate body 1 is provided with a plurality of second threaded wire rings 12 for increasing the contact area of ​​the soil layer. The second threaded wire ring 12 is wrapped around the second threaded drill 9 and rotates simultaneously according to the second hexagonal nut 7.

[0025] The limiting rod 2 is provided with a plurality of second fixing rings 6 for adjusting the length of the second threaded drill 9 . The second fixing rings 6 are used to limit the adjustment distance of the second threaded drill 9 . The second fixing rings 6 abut against the second hexagonal nut 7 , and the bottom of the second hexagonal nut 7 abuts against the second fixing ring 6 .

[0026] An internal thread 13 for limiting the second thread drill 9 is provided in the plate body 1 . The internal thread 13 is used to clamp the second thread drill 9 and prevent the second thread drill 9 from detaching from the plate body 1 . One end of the second hexagonal nut 7 is matched with the internal thread 13 , and the second thread drill 9 is matched with the internal thread 13 .

[0027] The working principle of the utility model is as follows: the worker first rotates the first hexagonal nut 5 through a torque wrench to make the first threaded drill 8 continue to penetrate into the soil layer, and then rotates the second hexagonal nut 7 through a torque wrench to make the second threaded drill 9 continue to penetrate into the soil layer, and ensures that the bonding plate 10 at the plate body 1 remains vertical to the soil layer, and finally fixes the support rod 4 on the first fixing ring 3.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
