Technical Field
[0001] The utility model relates to the technical field of scaffolds, in particular to a flower basket assembled cantilever scaffold. Background Art
[0002] Scaffolding refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is a common term in the construction industry, referring to the use of scaffolding on the construction site for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly for construction workers to work up and down or for the outer safety net enclosure and high-altitude installation of components. To put it bluntly, it is a frame. Scaffolding is usually made of bamboo, wood, steel pipes or synthetic materials. Some projects also use scaffolding as a template. In addition, it is also widely used in the advertising industry, municipal administration, transportation roads and bridges, mining and other departments.
[0003] For example, the existing patent, publication number CN207582926U, its technical solution is to pre-embed the first connecting sleeve and the second connecting sleeve in the wall structure layer, connect one end of the cantilever supporting steel beam in the wall structure layer to fix it in the wall structure layer, and connect one end of the steel wire rope to the other end of the cantilever supporting steel beam, and then pass the other end of the steel wire rope through the first connecting sleeve and the second connecting sleeve respectively and then tie them to achieve the fixation of the cantilever scaffolding, wherein the steel wire rope has a pulling force on the cantilever supporting steel beam, which can prevent the cantilever supporting steel beam and the standard layer external frame located above the cantilever supporting steel beam from falling, so that the construction workers stepping on the cantilever supporting steel beam and the construction workers located in the standard layer external frame can obtain support force and can carry out construction on the cantilever scaffolding.
[0004] This type of cantilever scaffolding generally requires reserved openings on the wall. The previous construction must be sealed again, affecting the subsequent floor construction. The steel beams need to be removed before floor construction can be carried out, which makes the openings easy to seep water and increases the construction period. At the same time, traditional steel beams are unevenly stressed and have poor bending resistance. Utility Model Content
