[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figures 1 to 4 , is an embodiment of the utility model, which provides a technical solution: an arc-shaped scaffolding board, including

[0023] The arc-shaped scaffolding board body 1 is erected on the top of the scaffolding 2, and the arc-shaped side of the arc-shaped scaffolding board body 1 faces the inner wall of the cyclone 4. The arc-shaped scaffolding board body 1 can be combined with the original rectangular scaffolding board on the top of the scaffolding 2 to form a platform for construction workers to stand on. Because the arc-shaped scaffolding board body 1 is compatible with the inner wall of the cyclone 4, the construction gap between the scaffolding board and the inner wall of the cyclone 4 can be greatly reduced;

[0024] And a quick-assembly mechanism 3 arranged at the bottom of the arc-shaped scaffolding board body 1, including a U-shaped hanging seat 31 welded and fixed on the bottom surface of the arc-shaped scaffolding board body 1 and hung on the scaffolding 2, a rotating base bar 32 arranged on the inner surface of the U-shaped hanging seat 31, a cylindrical through rod 33 welded and fixed on one side of the rotating base bar 32 and simultaneously passing through the U-shaped hanging seat 31 and the scaffolding 2, and an L-shaped clamping seat 34 movably installed on the inner surface of the U-shaped hanging seat 31, and the top end of the rotating base bar 32 is clamped on the inner side of the L-shaped clamping seat 34, so that the arc-shaped scaffolding board body 1 and the scaffolding 2 can be quickly assembled.

[0025] Among them, circular through holes A311 are penetrated on both sides of the U-shaped hanging seat 31, and the circular through holes A311 are adapted to the cylindrical through rod 33. Circular through holes B21 are penetrated on the surface of both sides of the scaffolding 2, and the circular through holes B21 are adapted to the cylindrical through rod 33. The design of the two through holes is used for the smooth penetration and subsequent rotation of the cylindrical through rod 33.

[0026] Among them, a positioning block 35 is welded and fixed on the bottom surface of the U-shaped hanging seat 31, and a positioning hole 22 corresponding to the positioning block 35 is opened on the top surface of the scaffolding 2, so that when the U-shaped hanging seat 31 is hung on the top of the scaffolding 2, the positioning block 35 will enter the positioning hole 22 to perform preliminary positioning of the U-shaped hanging seat 31, which is convenient for the subsequent penetration operation of the cylindrical through rod 33.

[0027] Among them, the quick-loading mechanism 3 also includes an inner slide groove 37 opened inside the top of the U-shaped hanging seat 31, an inner slide seat 36 slidably set in the inner slide groove 37, and a return spring 38 installed between the inner slide seat 36 and the inner wall of the inner slide groove 37. One end of the L-shaped holder 34 passes through the inner slide groove 37 and is fixed to the inner slide seat 36. Under the pulling action of the return spring 38, the L-shaped holder 34 can be stably pressed on the top of the rotating base bar 32 during daily use to ensure the pressing stability of the rotating base bar 32. One end of the return spring 38 is fixed to the inner wall of the inner slide groove 37, and the other end of the return spring 38 is fixed to the inner slide seat 36 to ensure the stable installation of the return spring 38.

[0028] Among them, a circular block 341 is welded and fixed on the inner side of the bottom end of the L-shaped socket 34, and a limiting slot 321 for the circular block 341 to be inserted into the top surface of the rotating base bar 32 is opened, so that after the top end of the rotating base bar 32 is screwed into the inner side of the L-shaped socket 34, the circular block 341 will be inserted into the limiting slot 321, further limiting the rotating base bar 32, preventing the rotating base bar 32 from being screwed out from the inner side of the L-shaped socket 34 later, thereby ensuring the assembly stability of the arc-shaped scaffolding board main body 1 and the scaffolding 2.

[0029] The inner surface of the U-shaped hanging seat 31 is provided with a movable hole communicating with the inner slide groove 37 , and the movable hole is adapted to the L-shaped holder 34 to ensure smooth penetration and subsequent smooth movement of the L-shaped holder 34 .

[0030] In summary, when assembling the curved scaffolding board main body 1 with the scaffolding 2, the curved scaffolding board main body 1 is first erected on the top of the scaffolding 2, and the positioning block 35 is allowed to enter the positioning hole 22 to complete the preliminary positioning of the curved scaffolding board main body 1, and then the rotating base bar 32 is lowered, and the cylindrical through rod 33 is passed through the circular through hole B21 and the circular through hole A311 to simultaneously penetrate the scaffolding 2 and the U-shaped hanging seat 31 to complete the plug-in connection between the scaffolding 2 and the U-shaped hanging seat 31, at this time, the rotating base bar 32 is rotated upward so that the top end of the rotating base bar 32 can be screwed into the inner side of the L-shaped holder 34, and the circular block 341 is inserted into the limiting slot 321, so that the rotating base bar 32 can be stably limited by the L-shaped holder 34, thereby ensuring the assembly stability of the curved scaffolding board main body 1 and the scaffolding 2, and the assembly convenience between the two is high, and the combined assembly and subsequent dismantling can be quickly completed at the construction site.
