[0002] The disc-type scaffolding is a new type of straight-insert steel pipe scaffolding with a self-locking function. The main components are uprights and crossbars. The disc-type node structure is reasonable, and the uprights transmit force axially, so that the overall scaffolding has high structural strength and good overall stability in three-dimensional space, and has a reliable self-locking function, which can effectively improve the overall stability and safety of the scaffolding, and can better meet the needs of construction safety. It has the characteristics of quick assembly and disassembly, labor saving, simple structure, stable and reliable, strong versatility, large bearing capacity, safety and efficiency, not easy to lose, easy to manage, and easy to transport.

[0003] The existing lap plate fixing method is either directly fixed to the pole by welding, or installed on the pole by fastening methods such as bolts. However, when the built scaffolding needs to be dismantled after the construction is completed, the removal and reinstallation of the existing lap plate are very cumbersome, which affects the progress of the construction and causes a waste of manpower. Summary of the invention

The sliding column and the overlapping plate are connected by a thrust spring. A connecting rod is provided on the locking block, and a limiting groove is provided on the pre-locking push block. The connecting rod cooperates with the limiting groove to prevent the locking block from rotating with the locking ring.

[0007] Furthermore, a semi-ring driving groove is provided on the locking ring, and a driving slider is provided on the overlapping disk. The semi-ring driving groove and the driving slider slide in cooperation to make the overlapping disk and the locking ring rotationally connected.

[0008] Furthermore, the overlapping plate is provided with a plurality of diagonal rod overlapping holes and a plurality of cross rod overlapping holes.

[0009] Furthermore, the locking block is provided with a locking thread for locking with the threaded rod or increasing the friction force between the threaded rod and the smooth rod, and the locking direction of the locking thread is opposite to the locking direction of the locking guide groove.

[0010] Furthermore, the pre-locking housing is provided with anti-slip grooves for preventing the pre-locking housing from rotating during pre-locking.

[0011] Furthermore, the pre-locking push block is provided with an anti-sliding block for increasing the longitudinal friction force during pre-locking.

[0013] Put the self-locking lap wheel onto the vertical pole and adjust it to the position where it needs to be fixed;

[0014] Rotating the overlap plate drives the pre-locking mechanism to perform pre-locking;

[0015] After the horizontal rod or the diagonal rod is overlapped, the locking ring is driven by the overlapping plate to perform self-locking.

[0016] Furthermore, the method for rotating the overlapping disk to drive the pre-locking mechanism for pre-locking is to first hold the anti-slip groove of the sliding ring to prevent rotation, and then rotate the overlapping disk to drive the vortex drive disk to rotate, and the vortex drive disk drives multiple pre-locking push blocks to move toward the center to pre-lock the opposing rods, and at the same time, the overlapping disk drives the locking ring to rotate through the driving slider and the semi-ring driving groove, and the locking ring drives the connecting column to slide in the horizontal rotating groove, and when the pre-locking is completed, the connecting column slides into the locking guide groove.

[0017] Furthermore, the method for self-locking by driving the locking ring through the overlapping plate after the horizontal bar or the diagonal bar is that the overlapping plate moves downward after being pressured by the diagonal bar or the horizontal bar, and the overlapping plate drives the connecting column to slide in the locking guide groove through the locking ring. At the same time, the locking ring spirally moves downward, and the inner wall of the locking ring continuously squeezes the multiple locking blocks, and the multiple locking blocks lock the vertical rod. The locking ring continues to rotate until the connecting column slides into the locking limit groove to complete the locking.

[0018] Beneficial effects: In this application, a locking ring is rotatably connected to the lapping disc, and a plurality of locking blocks are slidably connected to the locking ring.

A pre-locking mechanism for preventing the locking blocks from rotating with the locking ring is installed on the lapping disc. The lapping wheel disc can be pre-locked before locking and can be self-locked after bearing the load, making the installation of the lapping disc more convenient and labor-saving, simplifying the installation steps, reducing manual operation, and improving the installation efficiency.

[0019] In this application, a horizontal rotation groove and a locking guide groove are provided on the locking block. One end of the horizontal rotation groove is connected to one end of the locking guide groove, and a locking limit groove and an anti-detachment groove are provided at the other end of the locking guide groove, so as to limit the lapping wheel disc when the locking is completed, avoid the lapping wheel disc falling off due to external impact and causing safety accidents, and improve the use safety.
