Description

Support frame for automatic assembly and disassembly

The present invention relates to a support frame, in particular to a support frame used in the field of construction and capable of automatic assembly and disassembly.

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 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 the present invention can be automatically erected. 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 quality of public security can be improved, and the scaffolding can be quickly erected with the least manpower, which can reduce labor costs.

Please refer to Figures 13 to 15, which are another embodiment of the present invention. The main difference is that the outer oblique rod 40A is a double-tube form. Specifically, the lower pivoting portion 21A of the lower joint seat 20A has a lower pivoting piece 211A extending to the left and right, and a lower connecting hole 212 (not shown in the figure) is formed at both ends. The upper pivoting portion 31A of the upper joint seat 30A has an upper pivoting piece 312A extending to the left and right, and an upper connecting hole 313 (not shown in the figure) is formed at both ends. One end of the two outer oblique rods 40A located on the same side is respectively pivoted to the two outer oblique rods located on the same side. The lower pivot piece 211A has its other end pivoted to the upper connecting seat 12A. The form of the upper connecting seat 12A is changed accordingly.
