This achieves rapid expansion by applying force to the ring body and is convenient for storage, saving transportation space, and can be automatically stacked and set up scaffolding with automated equipment.

Description

Support frame with pressure ring and automatic assembly

The present invention relates to a support frame, in particular to a support frame applied in the field of construction, having a pressure ring and capable of automatic assembly.

Nowadays, for the construction and repair of building structures, scaffolding is set up for workers to climb on higher parts. For scaffolding with a lower height, about three floors or less, most of them are installed by hand. Four supporting legs and multiple crossbars are assembled to form a surrounding frame, and then pedals are placed on it. In this way, the scaffolding is gradually assembled and erected upwards until the predetermined height is reached. During this process, workers must continuously move materials from the flat surface to the top and assemble them. After the assembly is completed, they go down to the flat surface to pick up the materials and move them up again. Only by repeating the moving and assembling actions can the scaffolding be completed.

However, in the process of building the scaffolding, workers need to climb up and down, which is not only time-consuming and labor-intensive, but also prone to danger during the process of carrying and climbing. Especially when assembling a higher height support, the absence of a fence increases the degree of danger. Because the height is not high, workers usually do not wear relevant safety aids for convenience, which often leads to industrial accidents. Therefore, it is necessary to improve the above-mentioned problems.

A support portion 821 is provided, and the support portion 821 has a snap-fitting member that can snap-fit into the snap-fitting hole 151 of the support plate 15. This is an application of the prior art, so the detailed structure is not repeated. The robot arm is provided adjacent to the base assembly 80, and the invention is unfolded from the folded state to the opened state and placed in the base assembly 80 by the robot arm. Each straight rod assembly 10 is located on the inner side of each telescopic rod 82, and the snap-fitting hole 151 of each support plate 15 is snap-fitted into the telescopic rod. The supporting portion 821 of the first section is provided with a plurality of cross bars between the upper connecting seats 12 and the lower connecting seats 14, and a plurality of pedals 83 are provided on each cross bar. The user can also install a plurality of cross bars (not shown in the figure) on the middle fixing holes 131 on the same side according to the needs. After the complete assembly, the telescopic rods 82 of the first section are synchronously lifted; and another invention is deployed and set between the telescopic rods 82 of the second section, and the aforementioned assembly is repeated. The method is combined with the straight rod assemblies 10 located above. This is an application of the existing technology and will not be described in detail. The effect of automatically erecting the present invention is achieved. During the erection process, both the robot arm and the operator only need to be located on the ground to complete the erection. There is no need to climb up to assemble like the existing technology. Therefore, the danger of the construction process can be greatly reduced, the work safety quality can be improved, and the scaffolding can be quickly erected with the least manpower, which can reduce the labor cost.
