Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction engineering, and specifically relates to a hole protection device. Background Art
[0002] In the construction of construction projects, water conservancy and hydropower projects, holes are generally opened on the plates under construction to pass construction tools, such as erected poles. After the construction is completed, some construction tools will be removed from the holes, and the holes need to be sealed to reduce safety accidents caused by objects on the plates falling from the holes during subsequent construction, or to reduce safety accidents caused by workers stepping on the holes.
[0003] In the prior art, a cover plate is covered on the plate body, and bolts or expansion bolts are driven around the cover plate to fix the cover plate on the plate body. Since the openings on the plate body have different sizes, holes of different sizes need to be covered and protected by cover plates of different sizes. One cover plate can only be used for holes of one size, and the cover plate has a low reuse rate. Moreover, the cover plate is fixed with bolts or expansion bolts, and drilling is required to cause slight damage to the completed plate. The expansion bolts cannot be recovered after one-time investment. When the cover plate is removed later, the expansion bolts need to be processed. Utility Model Content

[0005] The present application provides a hole protection device, which is used to cover the hole of a plate body, and includes: a cover plate, a connecting rod, and a fastener;
[0006] The cover plate is used to cover the hole, and a strip-shaped through hole is formed on the cover plate;
[0007] The connecting rod comprises a connecting section and a limiting section, the extending direction of the connecting section is perpendicular to the extending direction of the limiting section, and the connecting section has an external thread;
[0008] The fastener is provided with a threaded hole, and the connecting section passes through the through hole and is threadedly connected to the fastener; the connecting section can move axially relative to the through hole;
[0009] The limiting section is spaced apart from the cover plate, and an extending direction of the limiting section is parallel to a plane where the cover plate is located; the plate body is located between the limiting section and the cover plate, and the fastener rotates and pushes the cover plate to move closer to the limiting section, so that the limiting section and the cover plate are both in contact with the plate body.
[0010] The fastener is a nut. The limiting section has an end surface for abutting against the plate body, the end surface is a plane, and an anti-skid rubber pad is fixed on the end surface.
[0011] In one solution, the extending direction of the strip-shaped through holes points to the center of the cover plate.
[0012] In one embodiment, there are multiple through holes, and the multiple through holes are distributed around the circumference of the cover plate.
[0013] In one embodiment, a washer is further included, through which the connecting rod passes to be connected to the fastener, and the size of the washer is larger than that of the fastener.
[0014] Specifically, the contact area between the gasket and the cover plate is greater than the contact area between the fastener and the cover plate.
[0015] In one solution, the baffle is a 0.5 mm thick iron sheet.
[0016] In one embodiment, a blocking piece is further included. The blocking piece is in a strip shape and covers the through hole. The blocking piece is located between the gasket and the fastener.
[0017] In one embodiment, the blocking piece is fixedly connected to an edge of the gasket.

[0035] In some embodiments, see Figures 1 to 5 , a hole protection device is provided, which is used to cover the hole 11 of the plate body 1, including: a cover plate 2, a connecting rod 3, and a fastener 4;
[0036] The cover plate 2 is used to cover the hole 11, and a strip-shaped through hole 21 is formed on the cover plate 2;
[0037] The connecting rod 3 has a connecting section 31 and a limiting section 32. The extending direction of the connecting section 31 is perpendicular to the extending direction of the limiting section 32. The connecting section 31 has an external thread.
[0038] The fastener 4 is provided with a threaded hole, and the connecting section 31 passes through the through hole 21 and is threadedly connected to the fastener 4; the connecting section 31 can move axially relative to the through hole 21;
[0039] The limit section 32 is spaced apart from the cover plate 2, and the extension direction of the limit section 32 is parallel to the plane where the cover plate 2 is located; the plate body 1 is located between the limit section 32 and the cover plate 2, and the fastener 4 rotates and pushes the cover plate 2 to move closer to the limit section 32, so that the limit section 32 and the cover plate 2 are both in contact with the plate body 1.
[0040] The fastener 4 is a nut. The limiting section 32 has an end surface for contacting with the plate body 1, the end surface is a plane, and an anti-skid rubber pad is fixedly provided on the end surface.
[0041] The cover plate 2 covers the hole 11, and then the connecting section 31 passes through the through hole 21 and is connected to the fastener 4. The connecting rod 3 is moved to make the limiting section 32 contact with the plate body 1. By tightening the fastener 4, the cover plate 2 and the limiting section 32 are clamped on both sides of the plate body 1 to ensure that the cover plate 2 and the hole 11 will not be separated.
[0042] Since the connecting rod 3 can move along the extension direction of the through hole 21 to facilitate better connection with the plate body 1, the cover plate 2 can cover more holes 11 of different sizes, and the cover plate 2 can be reused, thereby improving the reuse rate of the cover plate 2; and by tightening the fastener 4, the cover plate 2 and the limiting section 32 are clamped on both sides of the plate body 1, avoiding the situation of drilling holes on the plate body 1 to place bolts, thereby avoiding damage to the plate body 1.
[0043] In some embodiments, the extending direction of the strip-shaped through hole 21 points to the center of the cover plate 2. Pointing to the center of the cover plate 2 can better adjust the moving direction of the connecting rod 3 to adapt to different sizes.
[0044] In some embodiments, there are multiple through holes 21, and the multiple through holes 21 are distributed around the circumference of the cover plate 2. Providing multiple through holes 21 facilitates the connection rod 3 to pass through a suitable through hole 21 to better connect to the plate body 1.
[0045] Specifically, the number of the connecting rods 3 corresponds to the number of the through holes 21 , and a plurality of connecting rods 3 can more firmly connect the cover plate 2 to the plate body 1 .
[0046] In some embodiments, a gasket 5 is further included, through which the connecting rod 3 passes to connect with the fastener 4, and the size of the gasket 5 is larger than that of the fastener 4. The provision of the gasket 5 can increase the contact area between the fastener 4 and the cover plate 2, avoiding stress concentration.
[0047] Specifically, the contact area between the gasket 5 and the cover plate 2 is larger than the contact area between the fastener 4 and the cover plate 2, so as to avoid stress concentration.
[0048] In some embodiments, see Figure 4, and also includes a baffle 6, which is strip-shaped and covers the through hole 21; the baffle 6 is located between the gasket 5 and the fastener 4. The baffle 6 can reduce objects from falling from the through hole 21 and reduce safety hazards.
[0049] In some embodiments, the blocking piece 6 is a 0.5 mm thick iron sheet. The spacer 5 of this thickness can reduce the use of materials while ensuring the shielding function.
[0050] In some embodiments, see Figure 3 , the baffle 6 is fixedly connected to the edge of the gasket 5. Connecting the baffle 6 and the gasket 5 together can reduce the possibility of the baffle 6 falling and being lost.
[0051] In some embodiments, the cover plate 2 has a thickness of 5 mm and a side length of 500 mm, and the cover plate 2 is a steel plate. This thickness can meet the strength requirements of the cover plate 2, and this length can meet the size of most holes 11.
[0052] Finally, it should be noted that although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can make changes, modifications, substitutions and variations to the above embodiments within the scope of the utility model, which should all be included in the scope of protection of this application.
