[0002] With the rapid development of the construction industry and the improvement of construction technology, more and more super-high, large-span and large-volume construction projects are emerging. For the construction of high-altitude corridor concrete structures, a ground-type full-floor steel pipe fastener formwork frame is used. It is assembled in the podium, and then the steel structure corridor frame is hoisted to the installation position by a hoisting device for welding.

[0003] For example, the patent with announcement number CN206784942U discloses a high-altitude formwork frame for a building recessed corridor, including a steel structure support, an I-beam formwork platform erected on the steel structure support and the main structure of the building, the steel structure support includes a right-angled triangle support frame welded by vertical support I-beams, horizontal I-beams, and diagonal I-beams, the vertical support I-beams are fixed to the shear wall by tension bolts, the shear wall is fixed with a steel bracket supported at the bottom of the steel structure support, and the horizontal I-beams of the steel structure supports on both sides are connected by connecting steel plates; the I-beam formwork platform includes a plurality of cantilever main beam I-beams and connecting beam I-beams, the inner end of the cantilever main beam I-beam is anchored to the main structure of the building, the outer end of the cantilever main beam I-beam is fixed to the horizontal I-beam of the steel structure support, and the connecting beam I-beam is vertically cross-laid on the cantilever main beam I-beam. The utility model can facilitate construction, speed up construction progress, and reduce construction costs.

[0004] However, the high-altitude formwork for the building's recessed corridor in the application lacks a positioning structure for assembling the steel structure corridor frame at the ground podium, which leads to position deviation during hoisting, affecting subsequent aerial welding work. Utility Model Content

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, the materials of the positioning frame are hoisted and sent to the lower welding frame and the upper welding frame, and the positioning frame is sleeved on the surface of the lower welding frame and the upper welding frame. The base plate installed at the bottom of the positioning frame can facilitate the positioning frame to be quickly positioned and sleeved in the air, thereby improving the efficiency of construction. After the fixing is completed, the external crane device is removed and replaced with the lifting device at the hydraulic hoist. The steel cable at the hydraulic hoist is connected to the positioning frame and the limit rod is removed. Finally, the positioning frame is lowered to the surface of the podium by the hydraulic hoist. The steel frame is positioned by the position of the positioning frame, so that the construction personnel can accurately assemble the steel frame. After the assembly is completed, the positioning frame is removed, and the steel frame is lifted to the upper welding frame by the hydraulic hoist for welding to complete the construction. This device can locate the position of the lower welding frame and the upper welding frame on the podium, so that the staff can refer to the positioning frame when assembling the steel frame to avoid misalignment during subsequent hoisting and lifting.
