[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a foundation pit support frame for building construction that increases the side wall support area, including: a support plate 1, with adjusting screws 2 connected to both sides of the support plate 1, a rotating cylinder 3 provided on the outer side of the adjusting screws 2, and a side positioning plate 4 connected to the outer side of the rotating cylinder 3.

[0025] The side wall pressing adjustment assembly includes a guide tube 5, which is located inside the side positioning plate 4. An elastic connecting rod 6 is provided inside the guide tube 5, and a side wall pressure plate 7 is provided outside the elastic connecting rod 6. The side wall pressing adjustment assembly is used for the fitting adjustment of the pit side wall.

[0026] The positioning adjustment assembly includes a fixed connecting plate 12 and a plug rod 17. The fixed connecting plate 12 is located inside the support plate 1, and a swing pressure plate 14 is provided at the top of the fixed connecting plate 12. The plug rod 17 is located at the four inner corners of the support plate 1. The positioning adjustment assembly is used for the fastening adjustment of the support frame.

[0027] Specifically, such as Figure 2 As shown, the inner side of the elastic connecting rod 6 is connected to a snap-fit ​​positioning post 8. The snap-fit ​​positioning post 8 has multiple annular grooves inside, which facilitates the snap-fit ​​positioning of the positioning plate 11.

[0028] Specifically, such as Figure 2As shown, one end of the side positioning plate 4 is connected to a fixing frame 9, and the two inner ends of the fixing frame 9 are connected to guide rods. By setting the guide rods, the positioning plate 11 is controlled to move within the inner limit range of the fixing frame 9.

[0029] Specifically, such as Figure 2 As shown, a bidirectional threaded rod 10 is connected to the inner middle of the fixing frame 9. Both the upper and lower ends of the bidirectional threaded rod 10 are connected to positioning plates 11. The rotation of the bidirectional threaded rod 10 will control the positioning plates 11 to adjust their vertical position.

[0030] Specifically, such as Figure 4 As shown, a rotating support block 13 is connected to the top of the fixed connecting plate 12, and a swing pressure plate 14 is connected to the top of the rotating support block 13. The top wall of the swing pressure plate 14 is provided with an anti-slip groove 15, and an elastic connector 16 is connected to one side of the bottom end of the swing pressure plate 14. The rotating support block 13 and the swing pressure plate 14 are rotatably connected, and the swing pressure plate 14 and the elastic connector 16 are elastically connected. By cross-pressing the two swing pressure plates 14, the support plate 1 is more easily fixed at the bottom.

[0031] Specifically, such as Figure 4 As shown, the top of the plug rod 17 is connected to a screwing block 18, which is threaded to the support plate 1. The tip of the plug rod 17 is threaded to facilitate downward drilling. After reaching a certain depth, it is positioned by the threaded connection between the screwing block 18 and the support plate 1.

[0032] In this embodiment: an adjustable side wall pressure plate 7 is set on the outside of the side positioning plate 4. After the side wall pressure plate 7 is attached to the outer wall of the foundation pit, it is positioned by adjusting the positioning plate 11. This can increase the support area between the support frame and the side wall of the foundation pit during installation and improve the stability of the installation. When installing the support frame, the plug rod 17 is set for plugging. The screw block 18 is threadedly connected to the support plate 1 to improve the fastening effect. The swing pressure plates 14 on both sides of the top are swinged and pressed by foot to increase the pressing speed.

[0033] The specific solution is as follows: When using the foundation pit support frame, the support plate 1 is first positioned. The insertion rod 17 is then inserted downwards for positioning. To facilitate the insertion of the insertion rod 17, it can be pressed and swung left and right by stepping on the swing pressure plate 14. The anti-slip groove 15 improves the anti-slip performance. Then, when the insertion rod 17 is inserted to a certain depth, it is positioned by the threaded connection between the screw block 18 and the support plate 1. Then, by the relative rotation between the rotating cylinder 3 and the adjusting screw 2, the side positioning plate 4 is controlled to be close to the side wall of the foundation pit. At this time, the side wall pressure plate 7 is adapted and adjusted under the connection of the elastic connecting rod 6 to fit more closely to the uneven side wall of the foundation pit. Then, the bidirectional threaded rod 10 is rotated to drive the positioning plate 11 to move up and down, and it is locked on the outside of the locking positioning column 8 for restriction. Finally, by the relative rotation of the rotating cylinder 3 and the adjusting screw 2, reinforcement is carried out, so that the combination of the side positioning plate 4 and the side wall pressure plate 7 fits more tightly with the side wall of the foundation pit, thereby improving the stability of the support frame installation and ensuring the efficiency of use.
