[0002] Walkway slabs are a professional term in the field of architecture, referring to structural components installed in industrial plants, tunnels, granaries, and other settings to facilitate the passage of personnel or equipment. Their core functions include load distribution, safe passage, and assisting construction operations. In single-story plants, walkway slabs serve as an auxiliary facility to the crane beam system, forming an enclosure structure together with skylights and exterior walls. In tunnel engineering, they meet the special environmental requirements through anti-slip design, compact structure, and high-strength steel.

[0003] Traditional metal walkway panels, especially those with metal mesh structures, rely on welding or bolts to directly fix the frame structure of adjacent panels for installation and connection. While welding is strong, it makes maintenance and replacement difficult later on. Although bolted connections are detachable, they are slow and affect the installation speed. Utility Model Content

[0018] like Figures 1-3 As shown, a metal walkway panel includes:

[0019] Metal mesh panels 1, when spliced ​​together in a straight line, can form a metal walkway panel;

[0020] Side seats 2 are fixedly connected to the front and rear ends of the metal mesh plate 1. A connecting groove 21 is opened on the upper right side of the side seat 2. A connecting plate 25 is fixed on the upper left side of the side seat 2. A connecting block 26 is fixed on the lower end of the connecting plate 25. The connecting block 26 is inserted into the connecting groove 21 and engages with the connecting groove 21. A horizontal slide 23 is opened at the front end of the side seat 2. A vertical slide 24 communicating with the horizontal slide 23 is opened at the upper end of the side seat 2. A convex nut is slidably connected between the horizontal slide 23 and the vertical slide 24. When splicing two metal mesh plates 1, the connecting block 26 of one metal mesh plate 1 is inserted into the connecting groove 21 of the other metal mesh plate 1 from top to bottom, so that the connecting block 26 engages with the connecting groove 21 to fix the metal mesh plates 1. The convex nut is designed to facilitate sliding the convex nut to align with the fixing parts on the fixing frame, thereby facilitating the fixing of the metal mesh plate 1 to the fixing frame.

[0021] Locking grooves 22 are opened at both ends of the inner wall of the connecting groove 21. A groove 261 is opened in the middle of the connecting block 26. Locking blocks 265 are symmetrically and elastically connected to the left and right sides of the groove 261. The locking blocks 265 are inserted into the locking grooves 22 one by one. The end of the locking block 265 near the locking groove 22 is arc-shaped. When the connecting block 26 is inserted into the connecting groove 21, the locking blocks 265 are moved into the groove 261 by pulling the distance closer. As the connecting block 26 is inserted into the connecting groove 21 until the locking blocks 265 correspond to the locking grooves 22, the locking blocks 265 can be spring-loaded into the locking grooves 22 to lock the connecting groove 21 and the connecting block 26.

[0022] The central bearing inside the groove 261 is connected to a shaft 262. A gear 263 is fixed to the outside of the shaft 262. The gear 263 is symmetrically connected to racks 264 on its front and rear sides. The end of the rack 264 is fixed to the locking block 265 on the same side. A spring 266 is connected between the head of the rack 264 and the other locking block 265. When the shaft 262 rotates, it can drive the gear 263 to rotate. As the gear 263 meshes with the two racks 264, the distance between the two racks 264 is brought closer. This causes the racks 264 to drive the locking blocks 265 to bring closer together. At this time, the locking blocks 265 will compress the spring 266, and the spring 266 will give the locking blocks 265 an elastic force.

[0023] The upper end of the connecting plate 25 has a rotating groove 251, and a rotating block 252 is rotatably connected inside the rotating groove 251. The lower end of the rotating block 252 is fixed to the upper end of the shaft 262, and a protrusion 253 is fixed to the upper end of the rotating block 252. A rubber ring 254 is fixed to the outside of the rotating block 252. The outer wall of the rubber ring 254 is in close contact with the inner wall of the rotating groove 251. By pinching the protrusion 253 and rotating the rotating block 252, the rotating block 252 can drive the shaft 262 to rotate. The setting of the rubber ring 254 can make the rotation of the rotating block 252 have a certain damping.

[0024] The convex nut includes a horizontal slider 27, a nut 28, and a vertical slider 29. The horizontal slider 27 is slidably connected inside the horizontal slide rail 23, and the vertical slider 29 is slidably connected inside the vertical slide rail 24. The lower part of the vertical slider 29 is fixed to the upper part of the horizontal slider 27. The nut 28 is embedded and fixed to the front end of the horizontal slider 27. When the convex nut needs to be slid, it is only necessary to push the vertical slider 29 so that the vertical slider 29 slides inside the vertical slide rail 24. The vertical slider 29 then drives the horizontal slider 27 to slide inside the horizontal slide rail 23, thereby aligning the nut 28 with the fixing component of the fixing frame, so as to facilitate the fixing of the metal mesh plate 1 to the fixing frame.

[0025] When disassembling the metal mesh plate 1, two workers pinch the protrusion 253 and rotate the rotating block 252. The rotating block 252 drives the shaft 262 to rotate. When the shaft 262 rotates, it drives the gear 263 to rotate. As the gear 263 meshes with the two racks 264, the distance between the two racks 264 is brought closer. This causes the racks 264 to drive the locking blocks 265 to bring closer together. At this time, the locking blocks 265 will compress the spring 266. As the locking blocks 265 move out of the locking groove 22, the metal mesh plate 1 can be disassembled upwards.

[0026] In summary, the connection between the two metal mesh plates 1 in this application is achieved through the engagement of the connecting block 26 on the connecting plate 25 with the connecting groove 21 of the side seat 2, and the mechanical locking mechanism consisting of gear 263, rack 264, locking block 265 and locking groove 22, combined with the preload of spring 266. This achieves a bidirectional and secure locking of the connection point, effectively resisting the loosening force caused by vibration, and greatly improving the reliability and long-term stability of the connection. At the same time, this structure enables quick assembly and disassembly without the need for welding or a large number of additional fasteners, significantly improving the efficiency of on-site installation, maintenance and replacement of plates.
