Description

Technical Field

[0001] This utility model relates to the field of construction sites, and more specifically, to a pedestrian overlay board above a pit in a building construction site. Background Technology

[0002] During construction, open-type hazards are often created, with pits and ditches being common examples. To ensure that pedestrians can pass through without being obstructed, pedestrian boards are usually erected at the top of these openings.

[0003] Traditional covering materials often suffer from drawbacks such as weak load-bearing capacity, easy deformation and cracking, slippery surface, and cumbersome installation. They not only fail to effectively ensure the safety of pedestrians passing overhead, but also cannot meet the needs of efficient deployment and long-term use in modern construction sites, posing potential safety hazards and management pain points. In particular, the inconsistent opening sizes make the splicing of pedestrian boards even more troublesome, requiring a lot of manpower. Furthermore, the pedestrian boards themselves are quite heavy, further increasing the labor intensity. Therefore, there is a need for a pedestrian board that can be quickly spliced ​​and has sufficient strength. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a pedestrian interlocking board above the pits and trenches in building construction sites. It can quickly splice two pedestrian boards and complete the lateral interlocking and bottom support activation during the splicing process, thereby effectively improving the strength of the spliced ​​board. At the same time, the anti-slip pads and anti-slip grooves can further improve its stability and strength, protecting the safety of pedestrians.

[0006] 2. Technical Solution

[0017] 3. Beneficial Effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] (1) This solution utilizes embedded plates and embedded slots, as well as plug-in parts and locking parts, to enable rapid splicing of multiple plates without the need for frequent and repetitive bolting and other fixing actions. With the fastening parts, the plug-in rod can achieve automatic locking when inserted into the plug-in slot. The locking parts work together to achieve positional stability, while the fastening parts ensure stable connection between the two, achieving the effect of plugging and fastening upon insertion. This simplifies the splicing difficulty and improves the ease of use of the device.

[0020] (2) This solution utilizes support plates and gears to enable the plug rod to automatically flip when it is inserted into the plug slot, allowing it to protrude directly. The bottom ends of the two plates are supported together, which effectively improves the overall strength and enhances the practicality and stability of the device. Attached Figure Description

[0031] Example:

[0032] Please see Figure 1-5 A pedestrian overhanging slab above a pit at a building construction site, comprising a slab body 1, and further comprising,

[0033] A number of plug-in parts 4 are fixedly installed on the side of the plate body 1. The other side of the plate body 1 is provided with a plug-in groove 103 that matches the shape of the plug-in parts 4. A locking part 5 is movably installed inside the plug-in groove 103. A fastening part 6 is also rotatably installed inside the plug-in groove 103. The bottom surface of the plate body 1 is also provided with a placement groove 104 that communicates with the plug-in groove 103. A support plate 105 is rotatably installed inside the placement groove 104. Gears 106 that are rotatably installed inside the plate body 1 are fixedly installed on both the left and right sides of the support plate 105.

[0034] The connector 4 includes a connector rod 401 whose size is adapted to the connector slot 103. The connector rod 401 has a fastening slot 402 on its left and right sides, and a locking hole 403 is also provided at the outer end of the connector rod 401.

[0035] It should be noted that the plate 1 in this application is made of modified material, which can resist strong external impact and has a long service life.

[0036] One end of the plate 1 is fixedly installed with an embedded plate 2, and the other end of the plate 1 is provided with an embedded groove 3 that matches the embedded plate 2. The fastening component 6 includes a fastening plate 601, one end of which is fixedly installed with a protruding rounded corner plate 602, and the other end of the fastening plate 601 is fixedly connected with a fastening block 603. A rotating shaft 604 is rotatably installed inside the fastening plate 601, and a torsion spring 605 is fixedly connected between the fastening plate 601 and the rotating shaft 604. The rotating shaft 604 is fixedly installed inside the plate 1. The shape of the fastening block 603 matches the shape of the fastening groove 402. The locking component 5 includes a pull ring 501, the bottom end of which is fixedly connected with a locking pin 502. A spring 503 is fixedly connected between the locking pin 502 and the plate 1. The bottom end of the locking pin 502 is set with a rounded corner structure, and its size matches the size of the locking hole 403.

[0037] Specifically, the anti-slip mat 102 and anti-slip groove 101 can respectively increase the friction when pedestrians come into contact with them, as well as the friction of the surface when it is built on the ground, thus providing a higher anti-slip effect and improving the overall stability. The shape adaptation of the snap-fit ​​groove 402 and the snap-fit ​​block 603 allows the plug rod 401 to first contact the protruding rounded corner plate 602 when it is inserted into the plug-fit groove 103, and then apply pressure to its surface to make it rotate, thereby driving the snap-fit ​​plate 601 to flip over as a whole, so that the snap-fit ​​block 603 can finally be locked into the snap-fit ​​groove 402 to ensure that the two plates 1 cannot be axially offset when connected. The torsion spring 605 can make the snap-fit ​​plate 601 retract into the plate 1 when it is not subjected to external force, improving the overall aesthetics of the plate 1. Finally, the pull ring 501 can be inserted into the locking hole 403 to further fix the overall insertion position of the plug rod 401, ensuring the stability of use after splicing.

[0038] A rack 404 is fixedly connected to the bottom of the plug rod 401, and the rack 404 and the gear 106 mesh with each other;

[0039] Specifically, when the rack 404 enters the insertion slot 103 along with the insertion rod 401, it works in conjunction with the gear 106 to drive the support plate 105 to rotate as a whole, so that the outer end of the support plate 1, which was originally inside the bottom of the plate 1, can rotate to the bottom of the other connected plate 1, thereby achieving the effect of enhancing the stability of the connection.

[0040] The working principle of this utility model is as follows: When the plates 1 need to be horizontally spliced, the insertion rod 401 of the first plate 1 is directly inserted into the insertion slot 103 of the corresponding position of the second plate 1. During the process, the protruding rounded corner plate 602 is displaced under pressure and forced to rotate, causing the fastening block 603 to rotate out and lock into the inside of the fastening slot 402, thus locking the insertion rod 401. When the insertion rod 401 passes the bottom end of the locking pin 502, it will also apply an upward thrust through its rounded corner structure. When the locking hole 403 and the locking pin 502 are aligned, the locking pin 502 is directly reset by the compressed spring 503 and inserted into the interior to complete the lateral locking of the entire plug rod 401. At the same time, as the plug rod 401 enters the plug groove 103, the rack 404 drives the gear 106 to rotate the support plate 105 out and support the bottom end of the connection between the two plates 1. When the plates 1 need to be longitudinally spliced, the embedded plate 2 and the embedded groove 3 can be slid into each other until they fit together.

[0041] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
