Problems solved by technology

When the existing cantilever frame is used, the stability of the structure between the cantilevered steel beam and the connecting beam is poor. Because the cantilevered steel beam and the connecting beam are not on the same level, it is not convenient to close and secure the overlapping place of the cantilevered steel beam and the connecting beam. Protection, the operation process is cumbersome when setting up the scaffolding sweeping pole on the suspension frame
Therefore, when the existing cantilever frame is used, the labor intensity is high when the operator performs safety protection and erects the sweeping pole.

Abstract

The invention discloses a cantilever frame of a tool type profile steel cantilever scaffold. The cantilever frame comprises a supporting structure and a base protection plate fixed above the supporting structure. The supporting structure comprises a plurality of horizontal cantilever girders, which are horizontally arranged, a plurality of longitudinal cantilever girders, which are longitudinally arranged, and a corner cantilever girder arranged on the corner of the building. Longitudinally arranged longitudinal connecting girders are connected between two adjacent horizontal cantilever girders, overhanging towards the same side of the building, as well as the adjacent corner cantilever girder and horizontal cantilever girders. Horizontally arranged horizontal connecting girders are connected between two adjacent longitudinal cantilever girders, overhanging towards the same side of the building, as well as the adjacent corner cantilever girder and longitudinal cantilever girders. The horizontal cantilever girders, the longitudinal cantilever girders, the corner cantilever girders, the horizontal connecting girders and the longitudinal connecting girders are on the same horizontal plane. The cantilever frame is smooth in the surface, convenient to perform enclosed safety protection and set up bottom horizontal tubes and high in operator safety during setting up of the scaffold and following works.

Description

technical field [0001] The invention relates to a force bearing system of a cantilevered scaffold, in particular to a cantilevered frame of a tool-type steel cantilevered scaffold. Background technique [0002] Cantilevered scaffolding is a kind of construction scaffolding erected by using the support structure suspended on the building. The body of the cantilevered scaffolding can be suspended in sections along the vertical direction of the building, which can meet the needs of external scaffolding of different heights. Cantilevered scaffolding makes up for the height limitation of floor-standing scaffolding, and is simpler than lifting scaffolding. With the increasing number of high-rise buildings, the application of cantilevered scaffolding is becoming more and more extensive. [0003] The cantilevered scaffolding is mainly composed of a cantilevered frame and a fastener-type steel pipe scaffold. The cantilevered frame is used as a load-bearing structure, and a cantilever...
