Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction equipment, in particular to an auxiliary device for dismantling a reinforced concrete inner support beam. Background Art

[0002] Internal support beams in underground structures are mainly used in deep foundation pit support systems to ensure the stability and safety of the foundation pit during excavation. When constructing deep foundation pits, the role of internal support beams is very important. They can resist the pressure from the soil and other external forces, such as groundwater pressure and seismic loads, to prevent slope instability or collapse. These support beams are usually made of reinforced concrete. They not only enhance the stability of the entire support system, but also effectively control the displacement of the soil around the foundation pit, thereby reducing the impact on surrounding buildings and infrastructure.

[0003] When the main structure is completed and reaches sufficient load-bearing capacity, the internal support beams need to be removed. The removal of support beams is a complex and time-consuming task. The usual method is to set up temporary support frames, cut the support beams into sections, and then load them with a crane for transportation. This removal method requires repeated installation and removal of support frames, which not only increases the labor intensity of the work, but also significantly increases labor costs. In addition, due to space limitations on the construction site, traditional removal tools such as forklifts are sometimes not applicable, because the lifting height of the forklift is often not enough to cover the height range of the support beams, making this task more difficult. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an auxiliary device for dismantling reinforced concrete inner support beams.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] An auxiliary device for dismantling reinforced concrete inner support beams comprises a rectangular upper frame, a lower frame located below the upper frame, four columns respectively fixedly connected to the corresponding corners of the upper frame and the lower frame, two load-bearing beams arranged in parallel and fixedly connected to the upper end of the upper frame, and two sleeves arranged in parallel and fixedly connected to the lower end of the lower frame; the sleeves are provided with insertion holes for forks to be inserted and connected; the load-bearing beams are parallel to the extension direction of the forks.

[0007] Preferably, reinforcing plates are provided at the locations where the upright posts are adjacent to the upper frame and the lower frame.

[0008] Preferably, a safety mechanism is provided on the lower frame body, near the mast of the forklift; the safety mechanism comprises a base fixedly connected to the lower frame body, one end of which is rotatably connected to the base via a rotating shaft, and the other end of which has a hook portion.

[0009] Preferably, the load-bearing beam is made of I-beam, and a slidable and adjustable slider is mounted on the load-bearing beam, and the lower end of the slider has a limiting portion extending to the wing plate of the load-bearing beam; a stopper is arranged on the side of the slider facing the mast of the forklift, and a chamfer is arranged at the upper end of the stopper; a threaded hole is arranged on the slider, and a bolt is screwed on the threaded hole.

[0010] Preferably, the upper frame, the lower frame and the columns are all made of I-beams, and are connected by welding.

[0011] The above technical solution has the following advantages:

[0012] 1. When the auxiliary device of the utility model is used, it is mounted on the fork of the forklift, and the auxiliary device is lifted to the beam section of the support beam to be removed by the fork, so that it contacts the support beam, thereby achieving effective support when the support beam is removed. When the beam section supported by the auxiliary device is cut off, the operator can lower the auxiliary device by controlling the fork, so that the cut beam section will fall with the auxiliary device, reducing the risk of direct falling and ensuring the safety of construction. Next, the forklift can be used to smoothly transfer the cut beam section to the stacking place, or another forklift can be used to lift and transport the beam section for subsequent processing or disposal.

[0013] 2. The utility model is used in conjunction with a forklift, which greatly improves the flexibility of construction. It is no longer necessary to repeatedly install and disassemble the support frame, which not only reduces the cost of disassembling and assembling the support beam, but also significantly improves the efficiency of disassembly and assembly. Compared with traditional dismantling methods, this method reduces the demand for labor, reduces labor costs, and also reduces potential safety hazards during construction. In addition, since a forklift is used as an auxiliary tool, the operation method can be flexibly adjusted according to the specific conditions of the site, further improving the convenience and efficiency of construction.

[0026] As attached Figure 1-3 As shown, an auxiliary device for dismantling a reinforced concrete inner support beam comprises a rectangular upper frame 1, a lower frame 2 located below the upper frame 1, four columns 3 respectively fixedly connected to the corresponding corners of the upper frame 1 and the lower frame 2, two load-bearing beams 4 arranged in parallel and fixedly connected to the upper end of the upper frame 1, and two sleeves 5 arranged in parallel and fixedly connected to the lower end of the lower frame 2; a socket 6 for a cargo fork to be inserted and connected is provided on the sleeve 5; the load-bearing beam 4 is parallel to the extension direction of the cargo fork.

[0027] As a further improved technical solution of this embodiment, reinforcing plates 7 are provided at the adjacent positions of the upright column 3 and the upper frame 1 and the lower frame 2. The reinforcing plates 7 can be connected to the upper frame 1 and the lower frame 2 by welding to enhance the strength of the connection.

[0028] As a specific technical solution of this embodiment, the upper frame 1, the lower frame 2 and the column 3 are all made of I-beams, which are connected by welding. Obviously, other suitable profiles can also be used.

When in use, the hook 11 is hung on the mast of a forklift, which can prevent the forklift's fork and the sleeve 5 from moving or falling out, especially when going up and downhill and accelerating operations are required.

[0031] In this embodiment, the load-bearing beam 4 is made of I-beam, and a sliding block 12 that can be slidably adjusted is mounted on the load-bearing beam 4. The lower end of the sliding block 12 has a limit portion 13 extending to the wing plate of the load-bearing beam 4; a stopper 14 is arranged on the side of the sliding block 12 facing the mast of the forklift, and a chamfer 15 is arranged at the upper end of the stopper 14; a threaded hole 16 is arranged on the sliding block 12, and a bolt 17 is screwed on the threaded hole 16.
