Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, and particularly relates to a scaffolding for building decoration. Background Art

[0002] With the gradual development of the construction industry, the height of buildings is gradually increasing. In order to meet the decoration needs of buildings, scaffolding is required during decoration. Generally, the scaffolding consists of multiple support steel pipes and pedals erected on the steel pipes. The pedals provide a standing platform at a high position for workers, enabling them to carry out decoration work on a designated area at a high position.

[0003] After retrieval, a scaffolding for building decoration disclosed in Chinese Patent Application No. 202320044914.2 relates to the technical field of building decoration, and particularly relates to a scaffolding for building decoration. It includes: a frame main body and an adjustment structure; the frame main body includes columns and a working platform; the columns are connected to the top corner ends of the working platform; the adjustment structure corresponds to each column; the adjustment structure is arranged at one end of the column close to the ground; the adjustment structure includes a screw rod and a support rod; the screw rod is rotatably connected to the column; the screw rod is connected to the support rod through threads; when the screw rod rotates, the support rod can move along the axis of the screw rod. In the prior art, when the scaffolding faces an environment with height differences, due to the lack of a fulcrum that can stably support the scaffolding, there are serious safety risks during construction. Compared with the prior art, this patent can provide a stable fulcrum for the scaffolding according to actual needs, thus effectively improving the safety of the scaffolding.

[0004] Although the above patent can provide a stable fulcrum for the scaffolding according to actual needs, thus effectively improving the safety of the scaffolding, in actual use, due to the decoration of buildings requiring the use of scaffolding at different positions, this patent lacks a corresponding moving structure. Each time it needs to be moved, it needs to be lifted and carried, which is time-consuming and laborious and not convenient for people to use. At this time, some scaffolding are installed with universal wheels at the bottom for easy movement. Since the braking method of the universal wheels is point-surface contact, the contact surface between the bottom of the universal wheels and the ground is small, resulting in small friction, which will affect the braking effect of the universal wheels, and thus the stability of the scaffolding is poor due to the braking problem of the universal wheels themselves, further affecting the safety of the project construction.

[0005] Therefore, it is necessary to further improve the existing scaffolding. Summary of the Utility Model

Then, the hollow column 11 can be rotated to separate it from the clamping block 19. At this time, the positioning bolt 9 can be rotated to separate it from the positioning groove 7, and then the lifting block 8 can be slid up and down, so that the height of the hollow column 11 can be adjusted. After the adjustment is completed, the positioning bolt 9 can be rotated in the reverse direction again to be clamped into the positioning groove 7 at the corresponding position. Then, the extension column 12 can be rotated to extend outward from the hollow column 11 until the brake block 15 fits against the ground and the brake block 15 presses against the ground. At this time, the universal ball 14 rotates in the brake block 15, thereby improving its braking effect. Then, similarly, the other three brake blocks 15 can be adjusted to make them all press against the ground, so as to achieve the braking effect on the universal wheel 6, and then the contact area with the ground can be increased, and the friction force can be strengthened, so that the universal wheel 6 can achieve a better braking effect, thereby providing the use safety.
