TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and particularly relates to a high-turnover convenient self-clamping hole protection device. BACKGROUND

[0002] In the process of building construction, in order to meet the needs of design and later installation, many holes need to be reserved on the floor. The holes without protection or not in place may cause workers to fall, articles to fall and other dangers, and even cause serious injury accidents. Therefore, effective safety protection measures must be taken during the construction process.

[0003] At present, the protection of horizontal holes in the relevant specifications of building construction is clearly regulated: when the short side length of the hole is 25mm-500mm, a cover plate with a bearing capacity meeting the use requirements should be used to cover the hole, the cover plate should be evenly placed around, and the cover plate should be prevented from moving. However, in the actual construction process, workers usually only use randomly cut wooden boards to cover the holes and rarely use nails to fix them, which makes the protection measures easily moved or unable to meet the size requirements of the hole, so that the expected protection effect cannot be achieved, and there is a great safety hazard. Even if some wooden boards are fixed on the floor with nails, the floor will be damaged when they are removed, and the wooden boards with nails randomly stacked on the construction site will also bring potential safety hazards, and it is also difficult to use them for turnover. Because the material properties of the wooden board are complex, it is easy to be damaged during use, and the bearing capacity is difficult to calculate and verify. SUMMARY

[0032] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the sleeve 3 is provided with an adjusting screw 31, the cover plate 5 is threadedly connected with the adjusting screw 31, and the adjusting screw 31 is arranged within a range of 80-150 mm from the lifting piece 8.

[0033] The fixed handle 1 and the sleeve 3 are detachably connected.

[0034] As shown in the drawings, Figure 4 and Figure 5 The end of the clamping rod 10 is provided with an anti-skid block 101.

[0035] The clamping rod 10 and the connecting rod 7 are detachably connected.

[0036] As shown in the drawings, Figures 1 to 3 The sleeve 3 is provided with an array of reflective strips 32.

[0037] The cover plate 5 is a prefabricated cover plate 5.

[0038] As shown in the drawings, Figure 4 The cover plate 5 is provided with a stiffening rib 51.

[0039] Principle and operation process

[0040] The present application utilizes the principle of lever to realize the clamping action of the clamping rod 10 on the cover plate 5. One end of the movable handle 2 in the hand-held mechanism is rotationally connected with the fixed handle 1, and the other end is rotationally connected with the pull rod 4. When the movable handle 2 is operated, the movable handle 2 rotates around the connection point with the fixed handle 1, driving the pull rod 4 to slide in the sleeve 3. The movement of the pull rod 4 will cause the corresponding displacement of the lifting piece 8 provided at the end thereof. Since the lifting piece 8 is provided with an array of grooves, the gear 9 at the end of the clamping rod 10 is in meshing connection with the lifting piece 8, and when the lifting piece 8 moves up and down, the gear 9 will drive the clamping rod 10 to rotate around the connection point with the connecting rod 7. At the same time, the spring 6 is provided on the side of the lifting piece 8 close to the fixed handle 1, one end of which is in abutment with the lifting piece 8 and the other end is in abutment with the connecting rod 7, and the spring 6 plays a role of auxiliary reset and providing a certain clamping force pre-tightening. In the rotating process of the clamping rod 10, the clamping rod 10 cooperates with the cover plate 5 to realize the clamping of the floor slab. The anti-skid block 101 provided at the end of the clamping rod 10 further increases the friction between the cover plate 5, preventing the cover plate 5 from moving, and better ensuring the stability after clamping.

[0041] The sleeve 3 is provided with an adjusting screw 31, and the cover plate 5 is threadedly connected to the adjusting screw 31. By rotating the cover plate 5, the spacing between the cover plate 5 and the clamping rod 10 can be conveniently adjusted according to the thickness of the floor slab. The adjusting screw 31 is arranged within a range of 80-150 mm from the lifting piece 8, which is the thickness range of most floor slabs in the construction process, which can ensure the stability of the device structure and the effective transmission of the clamping force, and at the same time, the cover plate 5 can flexibly adapt to the protection requirements of floor slabs of different thicknesses.

[0042] The prefabricated cover plate 5 can be selected according to the size of the hole, and is replaced to meet the protection needs of various holes. The cover plate 5 is provided with a stiffening rib 51, which improves the bearing capacity of the cover plate 5 and better guarantees the safety of protection. The sleeve 3 is provided with an array of reflective strips 32, which can reflect light at night to improve safety and warn construction personnel, avoiding the construction personnel from colliding with the protection device due to insufficient light.

[0043] In use, first, the prefabricated cover plate 5 of appropriate size and the clamping rod 10 of corresponding length are selected according to the size of the hole. Then, the device is moved to the hole position with the sleeve 3 perpendicular to the floor plane, and the movable handle 2 is pressed downward. The movable handle 2 drives the pull rod 4 to move upward in the sleeve 3, and the lifting piece 8 at the end of the pull rod 4 moves upward. Since the lifting piece 8 is engaged with the gear 9 at the end of the clamping rod 10, the clamping rod 10 rotates around the connection point with the connecting rod 7 to the cover plate 5. At this time, the clamping rod 10 is in a gathered state, and part of the clamping rod 10 is inserted into the hole on the floor. Then, the movable handle 2 is released, and the spring 6 returns the clamping rod 10 to the initial state. At this time, the clamping rod 10 cooperates with the cover plate 5 to clamp the floor and block the hole.

[0044] If the fit between the cover plate 5 and the floor or the clamping force is not uniform during clamping, the position of the cover plate 5 on the adjusting screw 31 can be rotated to adjust the distance between the cover plate 5 and the clamping rod 10. According to the actual situation, the cover plate 5 is appropriately rotated in or out to achieve the best protection and clamping effect.

[0045] During use of the protection device, the clamping state of the clamping rod 10, the integrity of the cover plate 5, and the warning effect of the reflective strip 32 are regularly checked. If the clamping rod 10 is loose, the cover plate 5 is damaged, or the reflective strip 32 is not clear, etc., timely maintenance or replacement is performed. When the hole protection position needs to be changed or the size of the hole changes, the movable handle 2 is pinched, the clamping rod 10 is gathered, and then the protection device is taken out and the cover plate 5 and the clamping rod 10 are disassembled. The appropriate cover plate 5 and clamping rod 10 are selected, and the device is reinstalled at the new hole position according to the above installation and clamping operation process. During the entire use cycle, the characteristics of the cover plate 5 being detachable and the clamping rod 10 being replaceable, as well as the self-clamping and adjustable functions of the device, are fully utilized to achieve high turnover rate, improve economic efficiency, and guarantee construction safety.

[0046] Although the specific embodiments of the present application are described above in combination with the drawings, it is not a limitation on the scope of protection of the present application. Various modifications or variations made by those skilled in the art without creative labor on the basis of the technical solutions of the present application are still within the scope of protection of the present application.
