[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into vertical pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] In the process of building construction, scaffolding is needed.

[0028] Furthermore, the modular support and retaining frame is composed of four support rods 2, four lifting rods 4, two retaining rods 1 3 and two retaining rods 2 5. The overall outer contour of the modular support and retaining frame is a rectangular frame. The two retaining rods 1 3 are respectively connected transversely between the two support rods 2 on the long sides, and the two retaining rods 2 5 are respectively connected transversely between the two lifting rods 4 on the short sides, and the retaining rods 1 3 and the retaining rods 2 5 are perpendicular to each other.

Connect two first retaining rods 3 to two support rods 2 respectively. Insert four lifting rods 4 into the corresponding support rods 2. Then, sleeve height adjusting devices 7 on both of the two second retaining rods 5 and connect the two lifting rods 4 respectively. And the first retaining rod 3 is perpendicular to the second retaining rod 5, thus completing the modular support retaining frame. Place the modular support retaining frame at the four corners of the bottom plate 1 through the cooperation of the first connection block 12 and the connection groove 11. And at one end of the bottom plate 1 facing away from the modular support retaining frame, there are four positioning bases 8, which are fixed by adapting bolts. Place the top plate 6 at one end of the lifting rod 4 facing away from the support rod 2. And the bottom plate 1 has the same structure as the lifting rod 4. Select adapting bolts for connection. Determine the appropriate height of the scaffolding. Rotate the two height adjusting devices 7, and slide the fixing block 19 of the height adjusting device 7 in the upper surface sliding groove of the bottom plate 1 until the top plate 6 is lifted to the appropriate height. Then slide the two fixing blocks 19 along the second retaining rod 5 into the fixing groove 9 on the side of the sliding groove and select adapting bolts to fix and connect through the cooperation of the first connection hole 10 and the third connection hole 24. Thus, it is completed. The upper working layer can be continuously built on the top plate 6 in the above manner.
