Supporting tool for disassembling deep foundation pit supporting cross beam

Abstract

The utility model discloses a supporting tool for disassembling a deep foundation pit supporting cross beam. The supporting tool comprises stirrups below a supporting slitting body. And the hanging bracket is used for hooking and hanging the slitting body and is arranged above the stirrups at intervals. When the slitting body is cut and disconnected from the supporting cross beam to be dismantled, the slitting body is supported upwards by the stirrups and lifted upwards by the lifting frame, so that the slitting body is limited and cannot fall down at will to affect the safety of the construction environment; the problem that the safety of the construction environment is affected due to the fact that concrete, capable of crushing the supporting cross beam, of the excavator on the supporting cross beam freely falls down and rolls is solved.

Description

Technical Field

[0001] This utility model relates to a support fixture for disassembling a crossbeam supporting a deep foundation pit, belonging to the field of building construction technology. Background Technology

[0002] When constructing high-rise buildings, a foundation pit of a certain depth is sometimes excavated on the side of a road intersection. To resist the earthwork pressure from the roads on both sides of the pit, support beams are needed on the sides of the pit through reinforced concrete pouring. After the building's floor slabs are poured, the support beams above the floor slabs need to be removed to allow for subsequent floor slab pouring.

[0003] Existing technologies for dismantling support beams are available in Chinese Patent Publication No. CN110158609B. Although excavators can break the support beams, the concrete of the support beams will fall downwards and roll around after being broken, which will affect the safety of the construction environment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a support tooling for disassembling crossbeams in deep foundation pits.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a support fixture for disassembling a crossbeam supporting a deep foundation pit, comprising:

[0007] The stirrups support the section below;

[0008] The hooks are used to suspend the cut sections, with the hooks spaced above the stirrups.

[0009] It also includes the building floor slab located in the deep foundation pit space between the dismantled and undismantled support beams, with stirrups placed on the building floor slab.

[0010] The hanger includes: a load-bearing arch spaced apart on the periphery of the cut-off body;

[0011] The hooks and claws connected by the retractable telescopic component A are two located on both sides of the inner surface of the load-bearing arch to hook the bottom of the cut-off body.

[0012] The hook and claw are fixed with a retractable telescopic component B.

[0013] The top of the load-bearing arch has a hook with a lifting cable for hoisting.

[0014] The hoisting cable is connected to a liftable telescopic component C. The fixed end of the telescopic component C is fixed to the rolling arch. A rolling ball is installed on the inner surface of the rolling arch and makes rolling contact with the upper support beam to be removed.

[0015] The telescopic components A, B, and C are hydraulic telescopic rods.

[0016] The hoisting cable is connected to a tower crane used in the construction environment.

[0017] The beneficial effects of this utility model are as follows: when the cutting body is cut and disconnected from the support beam to be dismantled, the cutting body is supported upward by the stirrups and lifted upward by the hanger, which restricts the cutting body from falling downward at will and affecting the safety of the construction environment. This solves the problem that the concrete that the excavator can break on the support beam will fall downward at will and roll, affecting the safety of the construction environment.

Detailed Implementation

[0022] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0023] like Figures 1 to 3 As shown.

[0024] This application discloses a support fixture for dismantling a crossbeam supporting a deep foundation pit, comprising:

[0025] Stirrups 2 are placed on the floor slab 1 of the building. The floor slab 1 is located in the space of the deep foundation pit 4 between the removed support beam 21 and the support beam 3 to be removed. There is a road 41 on the top of the deep foundation pit 4.

[0026] It also includes a hanger 5 spaced above the stirrup 2, which hooks the cut pieces 31 on the support beam 3 to be dismantled.

[0027] The hanger 5 includes: a load-bearing arch 51 spaced around the outer periphery of the split body 31;

[0028] The hook claws 53 are connected by a retractable telescopic member A52. The hook claws 53 consist of two hooks located on both sides of the inner surface of the force-bearing arch 51 to hook the bottom of the cutting body 31. A retractable telescopic member B54 is fixed on the hook claws 53. When the hook claws 53 hook the bottom of the cutting body 31, the telescopic member B54 extends and abuts against the inner side of the force-bearing arch 51 to play a certain limiting role.

[0029] The top of the load-bearing arch 51 has a hook 55, which is connected to a liftable telescopic component C57 via a cable 56. The fixed end of the telescopic component C57 is fixed to the rolling arch 58. The inner surface of the rolling arch 58 is equipped with a rolling ball 59 that makes rolling contact with the upper support beam 3 to be removed. The telescopic components A52, B54, and C57 can all be constructed using hydraulic telescopic rods or threaded telescopic rods or other telescopic components to achieve their telescopic function.

[0030] The hook 55 on the load-bearing arch 51 can be connected to the tower crane used in the construction environment via the lifting cable 56.

[0031] The present application discloses a method for dismantling a crossbeam supporting a deep foundation pit, comprising the following steps:

[0032] The stirrup 2 of the deep foundation pit support beam dismantling tool is placed on the floor slab 1 of the building body below the support section 31, and the lifting frame 5 is hooked on the bottom of the section 31.

[0033] When the large sections 31 cut from the support beam 3 to be dismantled are disconnected from the support beam 3, the stirrups 2 support the sections 31 upwards and the hanger 5 lifts the sections 31 upwards, thus preventing the sections 31 from falling downwards and affecting the safety of the construction environment. This solves the problem that the concrete that the excavator can break on the support beam will fall downwards and roll, affecting the safety of the construction environment.

[0034] Then, the gantry 5 lifts the segmented body 31 and moves it onto the floor slab 1 of the building body, thereby dismantling the crossbeam supporting the deep foundation pit.
