[0027] Reference Figures 1-6 As shown, this utility model provides a technical solution: a nano single-sided stepped steel mesh template, including a steel mesh template body 1, and a stepped layer 2 that can be detachably installed on the surface of the steel mesh template body 1.

[0028] The following is a detailed explanation of its overall setup and function.

[0029] In this implementation scheme: two positioning strips 4 are fixedly connected to the lower surface of the stepped layer 2, and two strip-shaped holes 3 are formed on the surface of the steel mesh template body 1. The size of the strip-shaped holes 3 matches the size of the positioning strips 4. By setting the above structure, the disassembly of the nano single-sided stepped steel mesh template is facilitated. After disassembly, the steel mesh template body 1 and the stepped layer 2 are cleaned separately, which facilitates the deep cleaning of the nano single-sided stepped steel mesh template and reduces the cleaning time, thereby improving the cleaning efficiency of the nano single-sided stepped steel mesh template. A connecting pin 6 is fixedly connected to the surface of the positioning strip 4, and a rotating block 7 is rotatably connected to the side wall of the connecting pin 6. An arc-shaped groove 5 communicating with the strip-shaped holes 3 is opened on the surface of the steel mesh template body 1. During the twisting process, the rotating block 7 can be offset to the inner side of the arc-shaped groove 5. Both ends of the rotating block 7 are fixedly connected to the spring piece 8, and the other end of the spring piece 8 is fixedly connected to the support block 9. The setting of the support block 9 improves the stability of the locking after the rotating block 7 is rotated into the inner side of the arc-shaped groove 5.

[0030] Specifically, the spring piece 8 has a rhomboid structure. By setting the spring piece 8 with a rhomboid structure, the tightness of the contact between the support block 9 and the inner arc surface of the arc groove 5 is improved. The surface of the support block 9 is provided with anti-slip texture 10. The anti-slip texture 10 increases the resistance when twisting the rotating block 7, preventing the rotating block 7 from easily overlapping with the rotating strip and causing the step layer 2 and the steel mesh template body 1 to detach. Both sides of the support block 9 are provided with arc surfaces 11. The arc surfaces 11 on the support block 9 facilitate the insertion of the support block 9 into the inner side of the arc groove 5.

[0031] The working principle is that when the installation work between the steel formwork body 1 and the stepped layer 2 needs to be carried out, the rotating block 7 is first rotated to overlap the rotating block 7 and the rotating strip, at this time, the rotating block 7 and the positioning strip 4 can be sequentially inserted through the strip-shaped hole 3, the quick positioning work between the stepped layer 2 and the steel formwork body 1 can be realized, at this time, the rotating block 7 on the connecting pin 6 is rotated, the rotating block 7 can be misaligned and rotated to the inner side of the arc-shaped groove 5 in the torsion process, in the process of torsion of the rotating block 7, the elastic sheet 8 is extruded and shrunk by the supporting block 9, the arc-shaped surface 11 on the supporting block 9 is arranged, which facilitates the rotating-in work of the supporting block 9 on the inner side of the arc-shaped groove 5, after the rotating block 7 is rotated into the inner side of the arc-shaped groove 5, the locking work between the stepped layer 2 and the steel formwork body 1 can be realized, the supporting block 9 and the arc-shaped surface between the arc-shaped groove 5 are arranged in the rhombus structure, the tightness of the abutment is improved, and the anti-skid lines 10 are arranged, the resistance when the rotating block 7 is twisted is increased, the phenomenon that the stepped layer 2 and the steel formwork body 1 are separated after the rotating block 7 is easily overlapped with the rotating strip is avoided, when the stepped layer 2 and the steel formwork body 1 need to be separated, the rotating block 7 is rotated to overlap the positioning strip 4, the cleaning and separating work between the stepped layer 2 and the steel formwork body 1 can be realized, the subsequent cleaning work of the steel formwork body 1 and the stepped layer 2 is facilitated, the cleaning efficiency of the steel formwork body 1 and the stepped layer 2 is improved, the above structure is arranged, the flexible disassembly work of the nano single-sided stepped steel formwork is facilitated, the steel formwork body 1 and the stepped layer 2 are cleaned after disassembly, the deep cleaning work of the nano single-sided stepped steel formwork is facilitated, the cleaning time is reduced, and the cleaning efficiency of the nano single-sided stepped steel formwork is improved.
