Description

Technical Field

[0001] The utility model relates to the field of static demolition, in particular to a static demolition device for a concrete frame. Background Art

[0002] Concrete static demolition is a common demolition method that applies force to destabilize the concrete structure, allowing for removal and cleanup. It typically utilizes mechanical devices or tools and is capable of effectively demolishing large areas of concrete. Concrete static demolition is widely used in some housing construction applications and is currently the most advanced cutting and separation technology. Demolition is carried out in a layered, top-down, section-by-layer approach, first removing the non-load-bearing structure, followed by the load-bearing structure.

[0003] Concrete frame structures include frame structures, shear wall structures, frame-shear wall structures, and frame-core tube structures. When statically dismantling frame columns, shear walls, and frame beams in a concrete frame, the frame beams themselves have a large cross-sectional area and contain a large amount of steel bars. Therefore, the frame beams themselves are heavy, which can easily cause the steel bars and concrete blocks near the cut surface to fall during static dismantling. Furthermore, if the entire block falls downward, it can easily deform the load-bearing plate below, threatening the lives of nearby construction workers. Based on this, the present invention proposes a static dismantling device for concrete frames. Utility Model Content

[0023] See also Figure 1-4 The utility model provides a technical solution: a static demolition device for a concrete frame, comprising a load-bearing plate 1, a cutting groove 2 is opened on the inner side of the load-bearing plate 1, a receiving plate 3 is arranged under the load-bearing plate 1, and the receiving plate 3 and the bottom of the load-bearing plate 1 are both provided with load-bearing wheels 4, a lifting motor 5 is fixedly connected to the outer surface of the load-bearing plate 1, and a lifting rod 6 is arranged inside the load-bearing plate 1. The load-bearing plate 1 can provide load-bearing for the lifting motor 5 and the receiving plate 3 through the lifting rod 6. The cutting groove 2 can facilitate cutting of frame beams in four directions. Since the cutting groove 2 itself is relatively narrow, It can prevent flying stones from splashing onto the construction workers. When the frame beam falls, the receiving plate 3 can catch the frame beam to prevent the frame beam body, steel bars and concrete blocks from falling below. The lifting motor 5 can drive the lifting rod 6 to move upward, so that the frame beam after static demolition can be safely stored at the cutting floor. In addition, the bottom of the receiving plate 3 is also equipped with load-bearing wheels 4, so the receiving plate 3 can also carry the load-bearing beam to move, thereby solving the problem that when the whole piece falls, it is easy to deform the load-bearing plate below, and it will also threaten the life safety of nearby construction workers.

[0024] In this embodiment, the load-bearing wheel 4 includes a wheel frame 7, the top surface of the wheel frame 7 is rotatably connected to the bottom surface of the load-bearing plate 1 and the receiving plate 3, the outer surface of the wheel frame 7 is rotatably connected to the wheel hub 8, the outer surface of the wheel hub 8 is fixedly connected to a hard plastic plate 9, and the outer surface of the hard plastic plate 9 is fixedly connected to a soft plastic ring 10. The hard plastic plate 9 and the soft plastic ring 10 are both made of a high-performance engineering material, specifically polycarbonate or some polyurethane material, with good compressive strength and elastic recovery ability, so they can play the role of the load-bearing wheel 4 and there is no need to worry about nails or other sharp objects on the construction site puncturing the load-bearing wheel 4, making the equipment more practical on the construction site.

[0025] In this embodiment, the outer surface of the load-bearing plate 1 is fixedly connected to the fixed seat 11, the inner wall of the fixed seat 11 is fixedly connected to the slide 12, the outer surface of the lifting rod 6 is fixedly connected to the limit plate 13, the outer surface of the limit plate 13 is rotatably connected to the roller 14, the outer surface of the limit plate 13 and the inner side wall of the slide 12 are slidingly connected, and the outer surface of the roller 14 and the inner surface of the slide 12 are slidingly connected. When the lifting rod 6 moves up and down, it can drive the limit plate 13 and the roller 14, and the roller 14 can rotate on the slide 12 to reduce the friction between the limit plate 13 and the slide 12. At the same time, the slide 12 can also keep the limit plate 13 moving in a fixed direction to avoid excessive shaking or rotation of the positioning rod itself.

[0026] In this embodiment, a groove 15 is provided on the inner side of the fixing seat 11, and a circular plate 16 is fixedly connected to the outer surface of the groove 15. The bottom surface of the circular plate 16 is fixedly connected to the top of the lifting rod 6. When the lifting rod 6 moves downward to the minimum, the circular plate 16 will contact the groove 15. The groove 15 can serve as the minimum limit and load-bearing function for the circular plate 16 and the lifting rod 6.

[0027] In this embodiment, the outer surface of the load-bearing plate 1 is fixedly connected to a support frame 17, the outer surface of the support frame 17 is rotatably connected to a positioning wheel 18, and the outer surface of the positioning wheel 18 is slidably connected to a load-bearing belt 19. One end of the load-bearing belt 19 is wrapped around the output end of the lifting motor 5, and the other end of the load-bearing belt 19 is fixedly connected to the outer surface of the circular plate 16. The support frame 17 can provide support for the positioning wheel 18, and the lifting motor 5 can pull the circular plate 16 and the lifting rod 6 through the load-bearing belt 19. Due to the position of the positioning wheel 18, the load-bearing belt 19 can drive the circular plate 16 and the lifting rod 6 to move upward or downward when moving.

At the same time, the rubber roller 21 can rotate under the action of the rotating seat 20, thereby facilitating the pulling out of the frame beam that falls on the rubber roller 21.

[0029] In this embodiment, the receiving plate 3 is located on the bottom surface of the lifting rod 6 and is installed with an electromagnet 22 and a limit frame 23. The bottom end of the lifting rod 6 is fixedly installed with a connecting plate 24. The inner wall of the connecting plate 24 is slidably connected to the receiving frame 25. The inner side of the connecting plate 24 is installed with an electromagnet 26. The limit frame 23 can provide the farthest limit for the receiving frame 25. The electromagnet 1 22 can suck out the receiving frame 25 so that the receiving frame 25 provides support for the receiving plate 3. The electromagnet 2 26 can suck the receiving frame 25 into the connecting plate 24 so that the receiving frame 25 can be detached from the bottom surface of the receiving plate 3.

The electromagnet 1 22 can adsorb the receiving frame 25 into the limit frame 23, so that the lifting rod 6 and the receiving plate 3 are connected to each other, and then the concrete slab below and the associated frame beam are cut through the cutting groove 2. After cutting, the concrete block and the frame beam are easy to fall on the rubber roller 21, and then the crane is started to move the receiving plate 3 upward. When the bearing plate 1 and the rubber roller 21 clamp the frame beam with each other, the entire equipment is moved, and the electromagnet 1 22 is turned off and the electromagnet 2 26 is turned on. After turning on, the receiving frame 25 will be separated from the receiving plate 3, and the receiving plate 3 and the frame beam above can be pushed to move together. Then repeat the above operation to complete the subsequent disassembly.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
