Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a safety plugging device for small holes reserved at a construction site. Background Art

[0002] In a construction site, a small hole needs to be reserved on the floor between the upper and lower floors. After the small hole is opened, it needs to be blocked with a plug to prevent debris and other debris in the upper floor from flying from these small holes to the lower floor and injuring the construction workers on the lower floor. The existing plugs are generally made of local materials, using small wooden piers from the construction process, and plugging the small wooden piers into the small holes. Due to the size difference between the small wooden piers and the small holes, they generally protrude a part of the floor, which not only affects the appearance, but also occupies space and affects the construction operations of the construction workers. At the same time, workers often collide with the small wooden piers in the small holes during construction and material handling, which not only affects the workers' construction operations and the normal material handling, but also collides the small wooden piers out of the small holes, thereby causing the small holes to lose safety protection, causing the upper debris and other debris to fly from these holes to the lower floor and injure people and other safety incidents.

[0003] Therefore, the present invention designs a safe plugging device for small holes reserved at a construction site to at least solve some of the above-mentioned technical problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a safe plugging device for small holes reserved at a construction site, so as to at least solve some of the above-mentioned technical problems.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A safety plugging device for small holes reserved at a construction site comprises a covering plate for covering the small holes, a clamping mechanism arranged on the covering plate and clamped in the small holes, and the covering plate covers all the small holes.

[0007] Furthermore, the clamping mechanism includes a first clamping steel bar, a second clamping steel bar, and a connecting steel bar connected between the first clamping steel bar and the second clamping steel bar; the first clamping steel bar and the second clamping steel bar are distributed parallel to each other, the connecting steel bar is respectively perpendicular to the first clamping steel bar and the second clamping steel bar, the spacing between the first clamping steel bar and the second clamping steel bar is consistent with the diameter of the small hole, and the first clamping steel bar and the second clamping steel bar are inserted into the small hole.

[0008] Furthermore, the cover plate is provided with a first insertion hole and a second insertion hole respectively matched with the first clamping steel bar and the second clamping steel bar, the first clamping steel bar is inserted into the first insertion hole, and the second clamping steel bar is inserted into the second insertion hole.

[0009] Further, the connecting steel bar is located on the top surface of the covering plate and is parallel to the covering plate.

[0010] Furthermore, the first insertion hole has a diameter of 7 mm.

[0011] Furthermore, the second insertion hole has a diameter of 7 mm.

[0012] Furthermore, the first clamping steel bar has a length of 400 mm and a diameter of 6 mm.

[0013] Furthermore, the second clamping steel bar has a length of 400 mm and a diameter of 6 mm.

[0014] Furthermore, the first clamping steel bar, the second clamping steel bar and the connecting steel bar are formed by bending one steel bar.

[0015] Furthermore, the cover plate is circular, has a thickness of 20-30 mm, and a diameter at least twice the diameter of the small hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention has a simple structure, a scientific and reasonable design, is easy to use, can completely cover small holes, and the clamping mechanism can firmly assemble the covering plate into the small holes, effectively ensuring the safety of the small holes, preventing debris from flying from the small holes to the lower layer and injuring the construction workers on the lower layer, thereby ensuring construction safety. The covering plate is thin, does not affect the appearance of the construction environment, and does not affect the material handling and construction workers in building construction.

[0018] The present invention mainly includes a covering plate for covering a small hole, and a clamping mechanism installed on the covering plate and clamped in the small hole to ensure that the covering plate stably covers the small hole. The clamping mechanism includes a first clamping steel bar, a connecting steel bar and a second clamping steel bar connected in sequence. The first clamping steel bar and the second clamping steel bar are distributed parallel to each other and are both perpendicular to the connecting steel bar. A first insertion hole and a second insertion hole are provided on the covering plate. The first insertion hole and the second insertion hole have the same aperture diameter, both of which are 7 mm. The spacing between the first insertion hole and the second insertion hole is consistent with the diameter of the small hole. The first clamping steel bar and the second clamping steel bar are 40 mm in length and 6 mm in diameter. When in use, the first clamping steel bar is inserted into the first insertion hole, and the second clamping steel bar is inserted into the second insertion hole. The connecting steel bar is located on the top surface of the covering plate and connected to the covering plate. At the same time, the connecting steel bar is also parallel to the covering plate. Then the covering plate equipped with the clamping mechanism is covered on the small hole, so that the first clamping steel bar and the second clamping steel bar are inserted into the small hole at the same time. Since the spacing between the first clamping steel bar and the second clamping steel bar is consistent with the aperture of the small hole, the first clamping steel bar and the second clamping steel bar can be firmly inserted into the small hole, ensuring that the covering plate tightly and firmly covers the small hole, preventing debris from flying from the small hole to the lower layer and injuring the construction workers on the lower layer, thereby ensuring construction safety.

Since the spacing between the first clamping steel bar and the second clamping steel bar is consistent with the aperture of the small hole, the first clamping steel bar and the second clamping steel bar can be firmly inserted into the small hole, ensuring that the covering plate tightly and firmly covers the small hole, preventing debris from flying from the small hole to the lower layer and injuring the construction workers on the lower layer, thereby ensuring construction safety.
