Description

Construction method and construction equipment for roof overhanging flyover structure decoration dual-purpose frame Technical Field The application relates to the field of building construction, in particular to a construction method and construction equipment for a dual-purpose frame for decoration of a roof overhanging flyover structure. Background The cantilever inclined flyer plate roof is a common building roof structural design, the building flyer plate has a plurality of structures, the supporting height is higher, and the formwork supporting construction is more complicated and difficult. The formwork support construction is realized by conventionally using a pre-buried round steel compression ring, erecting overhanging I-steel on an overhanging support frame, or adopting a reserved groove to add diagonal bracing rods and unloading steel wire ropes. The conventional overhanging I-steel is erected to construct a formwork support, the I-steel occupies large indoor space, the processes of secondary structure, decoration and the like in the later period are affected to perform cross construction, the later period repair quality of the reserved I-steel is difficult to guarantee, and after the frame is disassembled in construction, a round steel sleeve ring is required to be cut off by electric welding, so that material waste is caused. And add bracing ram + draw and hang wire rope construction, then need set up the scaffold frame outside add a row of pole setting as operation platform and protection railing, and need reserve bracing ram recess, add and unload reinforcing means such as wire rope draw and hang and add horizontal pull rod, construction steps are more loaded down with trivial details, therefore still have room for improvement. Disclosure of Invention The application provides a construction method and construction equipment for a dual-purpose frame for decorating a roof overhanging flyover structure, which aims to reduce the damage of a supporting system to a building structure, reduce the indoor occupied space of the building and reduce the construction cost.
