Description

Technical Field

[0001] This utility model relates to the field of foundation pit support beam technology, and in particular to a detachable building foundation pit support beam device. Background Technology

[0002] The general section of the foundation pit support adopts a combination of bored piles and three internal supports. Other sections adopt an 800mm diaphragm wall + 1 concrete internal support + 2 composite steel supports + TRD trench wall reinforcement + triaxial mixing pile trench wall reinforcement + passive zone reinforcement inside the pit. The foundation pit support beam supports the surrounding soil and buildings to prevent soil collapse inside the foundation pit and settlement of the soil outside the foundation pit, thereby maintaining the stability of the foundation pit.

[0003] The foundation pit is supported by support beams to ensure its stable installation. However, traditional support devices usually involve bolting reinforcing rods between multiple support beams to enhance the lateral strength of the support beams and prevent them from collapsing. This installation method is cumbersome and does not allow for quick removal of the reinforcing rods. To address these issues, a detachable foundation pit support beam device is needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a detachable building foundation pit support beam device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A detachable building foundation pit support beam device includes a force-bearing cylinder 1, an angle plate 9 rotatably connected to the inner wall of the force-bearing cylinder 1, a protective cylinder 2 fixedly connected to the surface of the angle plate 9, an adjusting plate 3 slidably connected to the inner wall of multiple protective cylinders 2, a fixed semicircular plate 5 fixedly connected to the end of the adjusting plate 3 away from the force-bearing cylinder 1, a rotating semicircular plate 6 rotatably connected to the surface of the fixed semicircular plate 5, a support beam 4 installed between the fixed semicircular plate 5 and the rotating semicircular plate 6, and a positioning adjustment mechanism provided on the upper surface of the force-bearing cylinder 1.

[0022] By setting a fixed semicircular plate 5 and a rotating semicircular plate 6, the support beam 4 installed in the middle is limited and fixed. By setting an adjusting plate 3, its length is adjusted, and the position of the fixed semicircular plate 5 and the rotating semicircular plate 6 from the force-bearing cylinder 1 is changed. By setting a positioning adjustment mechanism, the length and angle are adjusted and then positioned to maintain a stable position.

[0023] In this utility model, the positioning adjustment mechanism includes multiple slots 10 formed on the upper surface of the force-bearing cylinder 1, and a positioning pin 11 is slidably connected to the inner wall of the angle plate 9. The positioning pin 11 is adapted to the slot 10, and a return spring 12 is sleeved on the surface of the positioning pin 11. One end of the return spring 12 is fixedly connected to the surface of the force-bearing cylinder 1, and the other end of the return spring 12 is fixedly connected to the surface of the positioning pin 11.

[0024] By setting a positioning pin 11, which engages with the slot 10, rotation of the angle is prevented. By setting a return spring 12, the positioning pin 11 is kept stable when inserted into the slot 10.

[0025] In this utility model, the inner wall of the protective cylinder 2 is rotatably connected to a threaded rod 8, and the surface of the adjusting plate 3 is fixedly connected to an anti-detachment plate 7. The surface of the threaded rod 8 is threadedly connected to the inner wall of the anti-detachment plate 7.

[0026] By setting the anti-detachment plate 7, the surface of the anti-detachment plate 7 is blocked by the inner wall of the protective cylinder 2, preventing the adjusting plate 3 from slipping out of the protective cylinder 2.

[0027] In this utility model, a knob 15 is rotatably connected to the inner wall of the force-bearing cylinder 1, a first bevel gear 14 is fixedly connected to one end of the knob 15, and a second bevel gear 13 is fixedly connected to the surface of the threaded rod 8, with the first bevel gear 14 meshing with the second bevel gear 13.

[0028] By setting the first bevel gear 14, the rotation of the first bevel gear 14 drives the second bevel gear 13 to rotate, which in turn drives the threaded rod 8 to rotate.

[0029] In this utility model, a pair of anti-detachment blocks 21 are fixedly connected to the surface of the rotating semicircular plate 6, and a fixing plate 19 and a limiting block 22 are fixedly connected to the surface of the fixed semicircular plate 5. The limiting block 22 is adapted to the inner wall of the anti-detachment block 21.

[0030] By setting the anti-detachment block 21, the position of the limiting block 22 is limited, thus maintaining the stable installation of the rotating semicircular plate 6 and the fixed semicircular plate 5.

[0031] In this utility model, a spring telescopic rod 18 is fixedly connected to the surface of the fixing plate 19, one end of the spring telescopic rod 18 is fixedly connected to the surface of the limiting block 22, and a toggle rod 20 is fixedly connected to the surface of the limiting block 22.

[0032] By setting the spring telescopic rod 18, the limit block 22 is driven to reset.

[0033] In this utility model, the surfaces of the rotating semicircular plate 6 and the fixed semicircular plate 5 are provided with multiple threaded holes 16, and the inner walls of the multiple threaded holes 16 are threaded with cross screws 17.

[0034] By setting the cross screw 17, the operator can use the cross screw 17 to position and clamp the support beam 4 located between the rotating semicircular plate 6 and the fixed semicircular plate 5, so as to adapt to the clamping requirements of support beams 4 with different diameters.

[0035] Working principle: In use, after placing the force-bearing cylinder 1 between multiple support beams 4, the operator can rotate the knob 15. The knob 15 drives the first bevel gear 14 to rotate, which in turn drives the second bevel gear 13 to rotate. The second bevel gear 13 then drives the threaded rod 8 to rotate, thereby adjusting the position of the adjusting plate 3 inside the protective cylinder 2. The adjusting plate 3 drives the fixed semicircular plate 5 and the rotating semicircular plate 6 to move to the support beam 4 and then stops. Rotating the rotating semicircular plate 6 wraps the support beam 4 between the fixed semicircular plate 5 and the rotating semicircular plate 6, so that the limiting block 22 on the fixed semicircular plate 5 is engaged in the anti-detachment block 21, maintaining stable positioning. Rotating the multiple cross screws 17 close to the support beam 4 can adjust the position of the support beam. 4. When clamping, if the angle of the protective cylinder 2 needs to be adjusted, first pull out the positioning pin 11 to release the insertion limit state of the positioning pin 11 on the slot 10. Rotate the angle disk 9, and the angle disk 9 will drive the protective cylinder 2 to adjust the angle. After the angle is determined, the positioning pin 11 can be inserted into the corresponding slot 10 to limit the rotation of the angle disk 9 and the protective cylinder 2 as a whole. Through the connection of multiple pairs of protective cylinders 2 and the adjustment plate 3, the stress stability of multiple support beams 4 on the transverse water surface is ensured. When disassembling, push the lever 20 to drive a pair of limit blocks 22 to move away from each other. After releasing the locking limit with the anti-detachment block 21, the rotation separation effect of the fixed semicircular plate 5 and the rotating semicircular plate 6 can be achieved, realizing the quick disassembly effect.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
