Technical Field

[0001] The utility model belongs to the technical field of cantilever scaffolds, in particular to a cantilever scaffold. Background Art

[0002] Cantilever scaffolding is a temporary structure used in construction. It uses the cantilever structure extending outward from the edge of the building structure to support the external scaffolding, transferring all or part of the load of the scaffolding to the building structure. Cantilever scaffolding has been widely used in current construction projects.

[0003] In the Chinese utility model patent with publication number CN219952626U, a new cantilever scaffold is disclosed, which can quickly assemble multiple card hole support pipes, saving the time of the workers and improving the installation efficiency of the workers;

[0004] After searching and combining with the actual cantilever scaffolding installation and construction experience, the above technical solution still has some defects and shortcomings: first, the adjustable support rods of the above cantilever scaffolding need to be assembled separately during installation, which affects the speed and efficiency of installation and construction, and its support strength is low, and it is not convenient for quick installation and positioning of the standing board. The existing technology requires the installation of steel pipes between two cantilever scaffolds, and the use of steel wire to tie metal mesh on the steel pipes, which increases the construction burden, and the installation is time-consuming and inefficient. Therefore, it is urgent to improve the existing cantilever scaffolding and provide a cantilever scaffolding. Utility Model Content

[0010] As a preferred implementation, the first support rod, the second support rod and the cantilevered crossbeam form a triangular structure.

[0011] As a preferred embodiment, the positioning base includes a fixing ring, a limiting groove, a long screw and a nut. The bottom end of the fixing ring is welded and fixed to the upper end surface of the cantilever beam. The outer wall of the fixing ring is provided with two symmetrically arranged limiting grooves. A long screw is installed through the interior of the fixing ring, and a nut is threadedly sleeved on the outer side of the threaded section of the long screw.

[0012] As a preferred embodiment, the standing board is movably sleeved on the outside of the fixing ring, and the standing board and the cantilevered crossbeam constitute a disassembly structure.

This can not only improve the connection stability between the supporting steel pipe and the fixing ring, but the fixing block can also press the standing board tightly, so that the standing board can be positioned while the supporting steel pipe is installed, which can improve construction efficiency. The installation of the standing board makes it convenient for people to walk during construction. BRIEF DESCRIPTION OF THE DRAWINGS
