Scaffold

Abstract

The present invention discloses a scaffold (1), which comprises an inner scaffold body (2), an outer scaffold body (3) and a wall connecting bar (9); wherein, the inner scaffold body (2) is arranged close to a building; the outer scaffold body (3) and the wall connecting bar (9) are arranged away from the building; small cross rods (4), which are arranged between the outer scaffold body (3) and the inner scaffold body (2), connect the outer scaffold body (3) and the inner scaffold body (2) together; the material of at least part of the inner scaffold body (2) is different from the material of the outer scaffold body (3); and moreover, the rigidity of the material of the outer scaffold body (3) is not less than the rigidity of the material of the inner scaffold body (2). Given that the outer scaffold body of the scaffold plays a main role in bearing and that the inner scaffold body is not a main bearing part, the outer scaffold body needs to be constructed with highly rigid material, while at least part of the inner scaffold body can adopt material with relatively low rigidity and strength, and thereby, the construction cost of the scaffold can be reduced. In the preferred embodiment of the scaffold, the inner scaffold body is made of material which can be easily cut, so a manual tool can easily cut the inner cross rods and / or inner upright rods of the inner scaffold body, and therefore construction is convenient.

Description

technical field [0001] The invention relates to a scaffold. Background technique [0002] Currently used scaffolding usually includes two rows of frame bodies inside and outside. The two rows of frame bodies are relatively arranged around the building and are all made of metal pipes. The inner and outer rack bodies are fixed on the wall of the building through the connecting wall rods, so that they are attached to the surface of the building, and the inner rack body is arranged close to the outer wall of the building. A small horizontal bar for connecting the two is arranged between the inner and outer rack bodies. When encountering convex structures such as balconies, air-conditioning panels, and railings that protrude from the surface of the building, it is necessary to disconnect the metal tubes of the inner frame body at the corresponding position to reserve the necessary construction space for the convex structures. . In addition, during the construction and decorati...

AI Technical Summary

Problems solved by technology

The defect of existing scaffolding is that, due to the ever-changing shapes of buildings, it is difficult to adapt to the metal tube scaffolding rods with fixed dimensions, sometimes cutting is required, the process is complicated, time-consuming and laborious, which increases the construction cost; in addition, because the entire scaffolding is made of Consists of metal tubes, so the overall cost is higher
