Description

Technical Field

[0001] The utility model belongs to the field of construction scaffolds and relates to an anti-dumping construction scaffold. Background Art

[0002] Scaffolding is a general term in the construction field, which refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed on construction sites, for construction workers to work up and down, or for peripheral safety net maintenance and high-altitude installation of components. During the use of existing scaffolding for small operations, due to the support of four supporting legs to ensure its stability, construction workers stand on the horizontal board of the scaffolding. Due to the constant movement of construction workers, the horizontal board is unevenly stressed, which can easily cause the scaffolding to shake or tilt, especially during the loading process, there is a risk of tipping over.

[0006] As a preferred solution of the utility model, the thread on the lower side of the limit nut is sleeved with the shaft sleeve on the upper side.

[0007] As a preferred solution of the utility model, the intersection of the left and right stabilizing bars is connected together by a rotating shaft; such a design improves the structural strength between the left and right stabilizing bars and improves the stability of the scaffolding.

[0008] As a preferred solution of the utility model, the top of the limit column is fixedly connected to the pull plate; by lifting the pull plate upwards, the limit column is pulled out from the through hole of the frame at the lowest end of the rectangular frame, which makes it easy to insert the fixing rod therein and put it on the limit column, thereby improving the convenience of disassembly and assembly of the fixing rod.

[0010] The beneficial effects of the utility model are as follows: by movably installing the anti-tilt mechanism at the lower end of the side frame, it is convenient to use the scaffold by unscrewing the rectangular frames at the four corners of the lower end of the side frame, then lifting the pull plate upwards, lifting the limit column, installing the fixing rod on the lifted limit column, and then releasing the pull plate. Under the action of the spring, the limit column is inserted into the through hole at the lower end of the rectangular frame, thereby fixing the rectangular frames on the left and right front and back sides, thereby increasing the supporting range between the four corners of the scaffold and the ground, effectively improving the anti-tilt ability of the scaffold during use, and improving its stability.
