Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and more specifically to a device for controlling the thickness of cast-in-situ concrete floor slabs of a high-rise residential building. Background Art

[0002] Currently, housing construction primarily relies on cast-in-place concrete structures. During construction, due to varying skill levels among construction workers and inadequate management by construction units, the thickness of cast-in-place concrete floor slabs can easily be poor, failing to meet design drawings and regulatory requirements. During the pouring process, if the thickness of the cast-in-place concrete floor slab is not effectively controlled, excessive thickness or thinness after molding will impact the quality of the project. Once molded, rectification is difficult and may require demolition and reconstruction, resulting in significant losses for the company. Furthermore, existing molds pour concrete inwards through a pouring port, making the interior invisible from the outside. Consequently, internal flatness cannot be controlled, potentially leading to uneven surfaces in the final set floor slab.

[0003] After searching, a concrete floor slab thickness control device disclosed in publication number CN214834882U includes a control rod, a measuring pressure plate, an elastic component and a plug for fixing the measuring pressure plate. The control rod is arranged vertically, and a fixing plate is horizontally arranged on the rod body. The bottom of the rod body is the tip of the control rod. The control rod body located below the fixing plate and above the tip of the control rod is provided with a scale and a through hole.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, the control rod cannot ensure that it remains vertical to the wall panel, which will affect the overall detection of the concrete thickness. For this reason, we propose a high-rise residential cast-in-place concrete floor thickness control device. Utility Model Content

[0022] Among them, the fixed adjustment mechanism 2 includes a fixed mounting sleeve 6, the upper and lower ends of the fixed mounting sleeve 6 are fixedly connected with a fixed connecting block 7, the internal movably connected with a movable connecting rod 8, one end of the movable connecting rod 8 is fixedly connected with a connecting limit plate 11, the other end of the movable connecting rod 8 is fixedly connected with a connecting end plate 9, a force spring 10 is fixedly connected between the connecting end plate 9 and the fixed connecting block 7, one side of the connecting end plate 9 is fixedly connected with a connecting detection plate 12, one side of the connecting detection plate 12 is symmetrically provided with a fixed mounting block 13, the internal movably inserted with a movable insertion rod 14, and one end of the movable insertion rod 14 is fixedly connected with a connecting pull ring 15.

[0023] The outer surface of the movable rod 14 and the inner side of the fixed positioning through hole 3 slide in contact with each other, so that one end of the movable rod 14 can be stably inserted into the inner side of the fixed positioning through hole 3 for connection and fixation.

[0024] Among them, the movable guide control mechanism 5 includes a movable guide rod 17, one end of the movable guide rod 17 is fixedly connected to a connecting end ring 18, and the other end of the movable guide rod 17 is fixedly connected to a connecting limit plate 19, so that the connecting end ring 18 can fit together with the surface of the concrete, so that the connecting rod 1 and the concrete are in a perpendicular state to each other. Then, when the connecting rod 1 is pushed, the connecting rod 1 can be in a vertical state and inserted into the interior of the concrete for inspection, which is easy to operate.

[0025] Among them, the connecting limit plate 19 is fixedly connected to the side away from the movable guide rod 17 with a connecting handle 20, which is convenient for moving the connecting handle 20 and can drive the connecting limit plate 19, the movable guide rod 17 and the connecting end ring 18 to move, thereby making adjustments and easy operations.

[0026] Among them, a fixing through hole 21 is symmetrically opened inside the connecting handle 20, and the inner side of the fixing through hole 21 and the outer side of the surface of the connecting limit plate 11 slide and fit with each other, so that the connecting limit plate 11 can move stably on the inner side of the fixing through hole 21, which is easy to operate.

[0027] Among them, a measuring scale 22 is provided on one side of the movable guide rod 17, which facilitates the connection and cooperation between the measuring scale 22 and the fixed guide limit frame 4, and observes the moving distance of the connecting rod 1, so as to measure the thickness of the concrete.

[0028] The working principle of the present invention is as follows: during use, when the concrete has not completely solidified, the position of the connection detection plate 12 is adjusted according to the detection standard, so that the connection detection plate 12 moves outside the surface of the connection plug rod 1, compressing the force spring 10, and then the connection pull ring 15 drives the movable plug rod 14 to move, so that the movable plug rod 14 can be inserted into the inside of the fixed mounting block 13 and the inner side of the fixed positioning through hole 3, thereby fixing the position of the connection detection plate 12. In this process, the movable connecting rod 8 can drive the connection limit plate 11 to move, so that the connection limit plate 11 can pass through the inner side of the fixed through hole 21, thereby stably adjusting, and then the connection end ring 18 is fitted with the concrete surface, and then the connection plug rod 1 is pushed , so that the end of the connecting rod 1 fits with the floor slab. At this time, the fixed guide limit frame 4 can move outside the surface of the movable guide rod 17, and then the scale corresponding to the fixed guide limit frame 4 is read to make a preliminary measurement of the thickness of the concrete. Then, the connecting handle 20 is pulled to drive the connecting limit plate 19, the movable guide rod 17 and the connecting end ring 18 to move, so that the connecting end ring 18 and the concrete surface are separated from each other. At this time, the connection detection plate 12 and the concrete surface are observed. When the concrete is tightly attached to the connection detection plate 12 without a gap, it can be determined that the thickness of the reinforced concrete floor slab cast here has met the design requirements. Otherwise, it does not meet the requirements, too much or too little, and filling or removal operations are performed. The overall structure is simple and the operation is convenient and quick.
