Description

Technical Field

[0001] The utility model belongs to the technical field of blocking reserved openings of building main bodies, and in particular relates to a reserved opening blocking auxiliary device. Background Art

[0002] At present, when sealing the reserved openings in the main body of the building, most of them adopt the wire hanging hole method, specifically, use the wire above the floor to pull the plywood below the reserved opening, then complete the concrete pouring and maintenance at the reserved opening, finally cut the wire and remove the plywood; some use the top support method, specifically use the top support to make the plywood below the reserved opening close to the lower end of the floor, then complete the concrete pouring and maintenance, and finally remove the top support and plywood.

[0003] However, when using the wire hanging hole method, part of the wire passes through the floor slab, which poses a risk of water leakage during later use, and the fixing effect of the plywood is unstable, resulting in poor concrete forming effect. When using the top support method, a more complex support system needs to be set up, and there is a lot of formwork removal work, which poses a greater risk to safety management.

[0035] It should be noted that the aperture of the through hole matches the outer diameter of the pipe 1 , so as to prevent concrete from flowing out of the gap between the plate 5 and the pipe 1 , thereby ensuring the sealing effect of the plate 5 .

[0036] In one embodiment, the clamp 2 is a detachable clamp to facilitate installation of the clamp 2 on the existing pipe 1 .

[0037] In one embodiment, the clamp 2 includes two clamp half rings, and the two clamp half rings are connected by bolts.

[0040] It is understandable that the anti-slip layer is provided to reduce the risk of relative sliding between the U-shaped angle steel 3 and the pipe 1 , so as to help firmly fix the clamp 2 on the pipe 1 , thereby helping to ensure the sealing effect of the plate 5 .

[0041] In one embodiment, the anti-slip layer is a rubber strip attached to the U-shaped angle steel 3, and the thickness of the rubber strip is 2 mm.

[0042] It is understandable that the rubber strip has a high friction coefficient and good anti-slip ability, which is conducive to meeting the requirements of the anti-slip layer; at the same time, the rubber strip can be compressed to further firmly connect the clamp 2 to the pipe 1.

[0043] In one embodiment, four U-shaped angle steels 3 are evenly arranged on the circumference of the pipeline 1 , and the U-shaped angle steels 3 have a thickness of 3 mm and a width of 20 mm.
