DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.

[0020] As Figures 1-4As shown, the present application provides a prefabricated scaffold, which comprises a stepping plate 3, a plurality of support rods 2 for supporting the stepping plate 3, a cross rod fixed between two adjacent support rods 2, the plurality of support rods 2 being arranged at the outer periphery of the stepping plate 3, the stepping plate 3 being fixed to the cross rod through a plurality of buckling members 4, and the support rod 2 comprising an upper rod 207, a lower rod 208, and a connecting rod, the connecting rod comprising a first rotating block 205 and a second rotating block 201 which are rotationally connected to each other, the first rotating block 205 being threadedly connected to the upper rod 207, and the second rotating block 201 being threadedly connected to the lower rod 208. The support rod 2 is designed as a multi-section connecting structure, so that the installation of the support rod 2 does not need to use bolts 404 for connection, but can be directly achieved by manual connection through the threads of the rod body itself. Further, the two ends of the upper rod 207 and the lower rod 208 can be provided with external threads, so that when the support rod 2 needs to be raised, the connection of the multi-section upper rod 207 and the multi-section lower rod 208 can be achieved by adding a connecting rod, improving the flexible adjustment of the length of the support rod 2. The structure of the present application improves the efficiency of the installation and disassembly of the scaffold, shortens the time occupied by the flow channel during the installation and disassembly of the scaffold, avoids the problem of congestion, and ensures the safety of people's lives.

[0021] Preferably, as shown in the drawings, Figure 2 and Figure 3 The connecting rod further comprises a connecting block 204 connecting the first rotating block 205 and the second rotating block 201, the connecting block 204 being cylindrical, flanges being formed at the two ends of the connecting block 204, and rotating grooves 203 being respectively formed in the first rotating block 205 and the second rotating block 201 for accommodating and rotating the flanges. The longitudinal section of the rotating groove 203 is T-shaped, so that the diameter of the bottom end of the rotating groove 203 is greater than the diameter of the opening, so that the flange can be rotated while being clamped at the bottom end of the rotating groove 203 and is not easy to fall out of the rotating groove 203. The provision of the first rotating block 205 and the second rotating block 201 allows the two ends of the connecting rod to rotate in opposite directions, so that the rotation of the first rotating block 205 and the second rotating block 201 can achieve screwing connection with the upper rod 207 and the lower rod 208, respectively. When disassembling, only the first rotating block 205 and the second rotating block 201 need to be rotated to disassemble the support rod 2, without the need to rotate the upper rod 207 and the lower rod 208 for installation and disassembly. In the case where the upper rod 207 and the lower rod 208 are not convenient to rotate, such as when other components have been installed, and the support rod 2 needs to be installed, or when the support rod 2 needs to be disassembled first, the provision of the first rotating block 205 and the second rotating block 201 improves the efficiency of installation and disassembly, and the installation and disassembly of the support rod 2 can be directly achieved by manual operation without the need for other tools.

Since the rotation of the first rotating block 205 and the second rotating block 201 is not affected by each other, the first rotating block 205 and the second rotating block 201 can be rotated in different directions respectively, so as to adapt to the threads in different directions, and the flexibility of connection is improved.

[0023] Preferably, as shown in Figure 4 The plurality of buckle members 4 are arranged along the axial direction of the cross rod. The buckle member 4 can pass through the stepping plate 3 and be sleeved on the cross rod, thereby buckling and fixing the stepping plate 3 and the cross rod, so as to fix the stepping plate 3 firmly, and the problem of sliding and falling is less likely to occur compared with the prior art in which the stepping plate 3 is directly laid on the cross rod.

[0025] Preferably, the stepping plate 3 is rectangular, and the four support rods 2 are arranged at the four corners of the stepping plate 3. The stepping plate 3 is generally rectangular, so as to have a longer operation space and a narrower width, so as to occupy less flow channel in a place with large flow, and avoid the problem of congestion.

[0027] Preferably, the buckling member 4 comprises an upper half ring 401, a lower half ring 405 and a bolt 404, both ends of the upper half ring 401 and both ends of the lower half ring 405 are respectively provided with an ear plate 402, and the ear plate 402 is provided with a connecting hole 403; when the footboard 3 is fixed on the cross rod through the plurality of buckling members, the upper half ring 401 is passed through the footboard 3 and buckled on the upper half of the cross rod, the lower half ring 405 is buckled on the lower half of the cross rod, and the ear plate 402 of the lower half ring 405 is aligned with the ear plate 402 of the upper half ring 401, and the bolt 404 is connected to the connecting hole 403 of the aligned ear plate 402.

[0028] When assembled, first align the lower rod 208 with the second groove 202, then rotate the second rotating block 201, so that the lower rod 208 and the second rotating block 201 are tightened, then align the upper rod 207 with the first groove 206, rotate the first rotating block 205, so that the first rotating block 205 and the upper rod 207 are tightened, so the assembly of the support rod 2 is completed, when disassembled, reverse operation is required, first loosen the first rotating block 205 to remove the upper rod 207, then loosen the second rotating block 201, so that the disassembly is completed, so that the effect of quick assembly and disassembly of the support rod 2 is achieved, then install the footboard 3, unscrew the bolt 404, pass the upper half ring 401 through the footboard 3, and then install the lower half ring 405 on the cross rod, align the upper half ring 401 and the lower half ring 405, then use the bolt 404 to pass through the connecting hole 403, tighten the bolt 404, lock the footboard 3 and the cross rod, so that the locking and fixing effect of the cross rod and the footboard 3 is achieved, then install the shear support, so that the entire scaffold is assembled.
