For example, patent CN201288415Y discloses a sectional gradual overhanging type external scaffold for high-rise buildings, which is constructed by pre-burying overhanging fixing members on the floor in advance, so as to facilitate the fixing of overhanging section steel. The structure of encorbelmenting of this kind of shortcoming lies in can only setting up the structure of encorbelmenting at the floor that is equipped with the built-in fitting, and the pre-buried size of pre-buried mounting is difficult to the accuracy, and the scaffold frame uses and demolishs the back, and the reuse can't be dismantled to the built-in fitting.
Still for example, patent CN202450761U discloses an overhanging scaffold, which includes an overhanging beam, wherein the upper surface of the overhanging beam is connected with an upright rod, an oblique rod and a tube seat, the overhanging beam, the upright rod and the oblique rod are connected to form a triangular bracket, and the tube seat is connected with a scaffold steel tube; the structure is characterized in that a clamping piece is connected below the cantilever beam and abuts against a floor slab of a building; the upright stanchion is connected with the pulling and fixing component, and the pulling and fixing component fixes the triangular bracket through the upright post of the building. Although the cantilever scaffold does not need to be installed by means of complicated processes such as embedded parts or punching, the cantilever scaffold is complex in structure, low in connection strength and not high in safety factor.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
