Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a quick-disassembly device for reserved deep holes in building concrete. Background Art

[0002] Where the building water supply and drainage risers and bathroom pipes pass through the floor slab, it is necessary to reserve holes for the risers during the pouring of the concrete floor slab. The traditional construction methods for pipe penetration holes are: 1. The wooden box hole method, that is, during the floor slab construction process, a square box is nailed into a wooden template at the place where a hole is needed, fixed to the template, and removed until the concrete reaches full strength. The disadvantage is that the mold box processing, installation, and removal are time-consuming and cannot be reused; 2. The casing direct burial method, that is, the pipe casing is directly pre-buried in place at the place where the riser passes through the floor slab. The disadvantage is that the casing pre-buried accuracy is difficult to control, which may cause the pipe and the casing to be out of center during the later installation of the pipeline, resulting in a decline in the quality of the project construction when the error is corrected, and economic losses are generated; 3. The post-opening method, that is, no reservation is made during the main construction process, and the floor slab is temporarily opened by mechanical drilling or other means at the required place during the installation of the pipeline. The disadvantage is that mechanical opening may cause significant damage to structural reinforcement, pre-buried wire pipes, etc.

[0003] According to the disclosed patent 201720520275.7, the double-layer quick-disassembly concrete floor hole reserver includes a plastic mold body, a T-shaped tightening bolt, an upper end covering template, a lower end covering template, an upper limit plate, a lower limit plate, and a self-tapping screw. The bottom end of the plastic mold body is sealed with the lower end covering template, and the upper end of the plastic mold body is covered with the upper end covering template. The self-tapping screw is welded to the bottom end of the T-shaped tightening bolt, and the upper limit plate and the lower limit plate are respectively fixed on the T-shaped tightening bolt. The T-shaped tightening bolt passes through the upper end covering template and the lower end covering template, and the upper end covering template is fixed by the upper limit plate, and the lower end covering template is fixed by the lower limit plate. The utility model is convenient to use and can be quickly installed and removed. After the concrete reaches a certain strength, the inner PVC pipe is removed, and the outer PVC pipe is quickly removed. By adopting the utility model, time and labor are saved, and the damage to the floor slab caused by subsequent construction can be avoided, and the quality of the project can be improved. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the inner PVC pipe can be removed after the concrete reaches a certain strength, the outer PVC pipe can be quickly removed and transferred to the next flow operation section for reuse; by adopting a double-layer quick-disassembly concrete floor hole reservation device, time and labor are saved, and the damage to the floor slab caused by subsequent construction can be avoided, and the quality of the project can be improved. However, during use, the traditional building concrete reserved deep hole quick-disassembly device also needs to remove the inner and outer PVC pipes separately, resulting in a large waste of removal time. Moreover, the PVC pipe is in contact with the concrete. In the process of removing the PVC pipe, the PVC pipe is pulled toward, and due to the large contact area between the PVC pipe and the reserved deep hole in the concrete, the reserved deep hole in the concrete will still be damaged. Therefore, it is necessary to design a new technical solution. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a quick-disassembly device for deep holes reserved in building concrete to solve the problem that the current traditional quick-disassembly device for deep holes reserved in building concrete needs to remove the inner and outer PVC pipes separately, resulting in a waste of a lot of removal time. Moreover, the PVC pipe is in contact with the concrete. During the process of removing the PVC pipe, the PVC pipe is pulled in the direction. Since the contact area between the PVC pipe and the deep hole reserved in the concrete is large, the technical problem of damage to the deep hole reserved in the concrete will still be caused.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a quick-disassembly device for reserved deep holes in building concrete, including an inner cylinder of the device, and also including:

[0006] A first fixed cylinder, fixed on both sides of the inner cylinder of the device;

[0007] A quick release mechanism extends into the first fixed tube, the quick release mechanism includes a second fixed tube, one side of the second fixed tube passes through the first fixed tube, and the second fixed tube extends into the first fixed tube, a movable plate is fixed to one end of the second fixed tube located in the first fixed tube, a spring is fixed to one end of the movable plate away from the second fixed tube, and an arc-shaped plate is fixed to one end of the second fixed tube away from the movable plate;

[0008] Square holes are provided on both sides of the top of the inner tube of the device, one end of an L-shaped connecting plate passes through the square hole, and the other end of the L-shaped connecting plate passes through the first fixed tube to fix a movable plate.

[0009] Preferably, a strip-shaped inserting plate is inserted between the two arc-shaped plate bodies.

[0010] Preferably, a semi-dome cover is fixed on the top of the strip-shaped plug board.

[0011] Preferably, a connecting rod is fixed on the top of the inner cylinder of the device, and a pull cover is fixed on the top of the connecting rod.

[0014] 1. The utility model combines the inner cylinder, the fixed cylinder and the arc-shaped plate body of the device, not only can the two arc-shaped plates be used to form two arc-shaped surfaces, but also after the strip plug plate is inserted between the two arc-shaped plates, the device can be formed into a ring shape, and then concrete is poured. When the reserved cylinder needs to be removed, the two arc-shaped plates can be driven to move separately by moving the L-shaped connecting plate, so that the two arc-shaped plates can be separated from the reserved deep holes in the concrete respectively, without the need to separate and take out the entire cylinder directly from the reserved deep holes in the concrete. Moreover, after the arc-shaped plates are separated, the entire device can be directly taken out, eliminating the need to remove the inner and outer PVC pipes separately, thereby solving the technical problem that the traditional quick-disassembly device for reserved deep holes in building concrete needs to remove the inner and outer PVC pipes separately, resulting in a waste of a lot of disassembly time.

[0015] 2. The utility model combines the strip plug plate and the semi-dome cover, so that the semi-dome cover can be respectively engaged at the two side positions of the connecting rod during pouring, and the strip plug plate can be inserted between the two arc-shaped plate bodies, so that the device can form an annular cylinder, which can realize the reserved deep holes during concrete pouring. When dismantling, due to the provision of the strip plug plate, the parts in contact with the inner wall of the reserved deep hole can be set to multiple, and multiple mold mechanisms can be taken out separately, which solves the technical problem that the contact area between the traditional PVC pipe and the concrete on the inner wall of the reserved deep hole is too large, and when taking them out together, it is more laborious and easy to cause damage to the concrete on the inner wall of the reserved deep hole.
