Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a hole protection device. Background Technology

[0002] Construction refers to all construction activities carried out on a construction site, including the design, construction, decoration, and maintenance of buildings.

[0003] During building construction, it is usually necessary to leave openings in the floor slab. To ensure the safety of construction workers and pedestrians, temporary protective devices are needed to cover the openings before installing cover plates and other components. Currently, most of these devices use wooden boards, steel plates, or other similar materials to cover the openings and secure them with pins.

[0004] However, these existing protective methods have significant drawbacks. Using wooden or steel plates and fixing them with pins can damage the original structure of the building during installation, potentially negatively impacting the overall quality and future use of the building. Furthermore, dismantling them after construction is quite cumbersome. Utility Model Content

[0005] To facilitate the installation and removal of opening protection devices, this application provides an opening protection device.

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses an opening protection device. (Refer to...) Figure 1 A hole protection device includes two sets of erection plates 1, a sliding plate body 2, and a protective cover plate 3. The two sets of erection plates 1 and the sliding plate body 2 are slidably installed to adapt to different hole sizes. The protective cover plate 3 overlaps with the erection plates 1 to seal and cover the hole, achieving a protective effect. The hole protection device of this application is used to protect holes opened in the horizontal plane; therefore, the "up" and "down" directions mentioned below refer to the height direction.

[0038] Reference Figure 1 and Figure 2 The erection plate 1 is Z-shaped, with an erection part 11 erected at the top of the opening and a sliding part 12 located below the opening. The sliding plate body 2 is a rectangular block with sliding slots 21 extending through both ends in the width direction for the sliding part 12 to insert into. In this embodiment, the sliding slot 21 has a T-shaped cross-section, which includes a first groove 211 and a second groove 212 from top to bottom. The inner wall width of the first groove 211 is greater than the inner wall width of the second groove 212. The sliding part 12 and the sliding slot 21 are fitted together, making the overall connection strength between the erection plate 1 and the sliding plate body 2 relatively stable.

[0039] The sliding plate 2 is also provided with a drive mechanism 4 for driving the erection plate 1 to slide along the sliding slot 21. The drive mechanism 4 includes a drive gear 41 rotatably mounted on the sliding plate 2 and a drive rod 42 coaxially fixed with the drive gear 41.

[0040] The sliding plate 2 has a drive groove 22 for accommodating the drive gear 41 and communicating with the sliding slot 21. The drive groove 22 extends along the height direction. The top of the drive groove 22 penetrates the top end face of the sliding plate 2, allowing the drive rod 42 to extend to the top of the sliding plate 2, facilitating the operator to rotate the drive gear 41. A sealing plate 43 is also provided at the opening of the drive groove 22 in the sliding plate 2. The sealing plate 43 has a through hole for the drive rod 42 to pass through, and a rotating bearing that rotatably engages with the drive rod 42 is provided on the inner wall of the through hole. The sealing plate 43 is fixed to the sliding plate 2 with bolts to reduce the probability of dust and impurities entering the drive groove 22 during construction.

[0041] A drive rack 121 is fixedly mounted on the top of the sliding part 12 along its length. The sidewall of the drive rack 121 is provided with toothed surfaces that mesh with the drive gear 41. When the user rotates the drive rod 42, it drives the drive gear 41 to rotate. The engagement of the drive gear 41 and the drive rack 121 causes the sliding part 12 to move back and forth within the sliding slot 21, thereby adjusting the distance between the two sets of supporting plates 1 to accommodate openings of different widths. In this embodiment, two sets of drive mechanisms 4 are provided on the sliding plate body 2, and the two sets of drive mechanisms 4 drive the two sets of supporting plates 1 to slide respectively.

[0042] Reference Figure 1 and Figure 3 The erecting plate 1 has mounting grooves 13 on opposite sides along its length. Each mounting groove 13 contains an elastic element 131 and a locking block 132. The elastic element 131 is a compression spring, with its two ends fixed to the inner wall of the mounting groove and the locking block 132, respectively. The side wall of the sliding plate 2 has a sliding groove 23 for the locking block 132 to be inserted. One side of the sliding groove 23 connects to the sliding slot 21, and the other side penetrates the side wall of the sliding plate 2. The locking block 132 also has a locking guide surface 1321 on the side facing the sliding groove to improve the efficiency of the locking block 132's insertion into the sliding groove 23.

[0043] In the normal state of the elastic element 131, the length of the locking block 132 extending out of the mounting groove 13 is greater than the horizontal width of the sliding bar groove 23. This causes a portion of the locking block 132 to extend to the outer wall of the sliding plate 2 after it is inserted into the sliding bar groove 23.

[0044] A fixing plate 24 is fixedly connected to the top of the sliding groove 23 on the side wall of the sliding plate body 2. The fixing plate 24 is arranged along the length of the sliding groove 23. The fixing plate 24 is fixed to the sliding plate body 2 by bolts or welding. The fixing plate 24 has fixing holes 241 extending through both end faces along its length, and fixing members 25 are arranged in the fixing holes 241. The fixing members 25 are bolts, and the top of the locking block 132 has a locking screw hole 1322 that is threaded into the fixing member 25. When the erecting plate 1 is moved to the required position, the erecting plate 1 is finally fixed by the cooperation of the fixing member 25 and the locking bolt.

[0045] Reference Figure 4 A protective cover plate 3 is installed at the top of the opening and is fixedly fitted with the erection part 11 to achieve a protective covering effect on the opening. Two sets of insertion posts 111 are spaced apart at the top of the erection part 11, and the arrangement direction of the two sets of insertion posts 111 is perpendicular to the sliding direction of the erection part 11. The protective cover plate 3 has insertion strip holes corresponding to the insertion posts 111. In this embodiment, the insertion posts 111 are threaded rods. The protective cover plate 3 has locking nuts 32 in the insertion strip holes that are threadedly engaged with the insertion posts 111 to ensure the stability of the protective cover plate 3 at the opening.

[0046] To facilitate the removal of the protective device, two sets of pull handles 26 are fixed at intervals on the top of the sliding plate 2. The pull handles 26 are U-shaped tubes with their openings facing downwards. The protective cover plate 3 has protective through holes 33 through which the pull handles 26 pass.

[0047] The implementation principle of the opening protection device in this application embodiment is as follows: the length data of the opening is measured in advance, the distance between the two sets of erection plates 1 is manually adjusted according to the measurement data, the erection plate 1 and the sliding plate 2 are fixed by the cooperation of the fixing part 25 and the locking block 132, the erection plate 1 and the sliding plate 2 are erected on the edge of the opening by pulling the handle 26, and then the protective cover plate 3 and the plug-in post 111 are plugged in accordingly, and finally the protective cover plate 3 is locked by the locking nut 32.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
