AI Technical Summary

Technical Problem

In the traditional construction of large beam and slab reserved openings, formwork support and hoisting technology are difficult to meet the requirements of complex space and large-span construction. The structural stability is insufficient, the construction efficiency is low, and the safety risks are high, especially when working at height, there is a risk of falling.

Method used

The frame beam formwork hanging device, which is composed of double-jointed channel steel main ribs and adjustable hangers, is combined with a hanging basket operating platform and a floor slab formwork hanging device. Through mechanical lifting and standardized prefabrication, a stable load-bearing system is formed, providing a safe high-altitude working space, and precise adjustment and fixation of the formwork are achieved through tension screws and slings.

Benefits of technology

It improves the structural bearing capacity and anti-deformation ability, reduces the risk of high-altitude operations, improves construction efficiency and quality, is suitable for large-scale opening construction in complex environments, and reduces safety risks and overall costs.

Abstract

The invention discloses a large beam and slab reserved hole suspended formwork construction structure and method, and belongs to the technical field of building construction. The structure comprises a frame beam hanging formwork device, a hanging basket operation platform and a floor hanging formwork device. In the frame beam formwork hanging device, a double-spliced channel steel main ridge frame is provided with poured structures on the two sides of a reserved hole and is connected through a fixing piece, the upper end of an adjustable hanging rod is connected with a double-spliced channel steel main ridge, the lower end of the adjustable hanging rod is connected with a channel steel beam supporting frame, and a beam side formwork assembly is formed by fixing a beam side covering bamboo plywood, a beam side secondary ridge and a beam side main ridge through a first opposite-pull screw. The hanging basket operation platform comprises a hanging basket frame which is hung above the double-spliced channel steel main edges through supporting assemblies. In the floor slab formwork hanging device, a first supporting steel pipe is arranged above a double-spliced channel steel main ridge, and a steel plate bottom formwork is connected with the first supporting steel pipe and the double-spliced channel steel main ridge through a second opposite-pull screw rod and a hanging belt. According to the large beam and slab reserved hole suspended formwork construction structure and method, the suspended formwork construction structure is stable and safe, construction is efficient and accurate, the cost is reduced, and the application range is wide.
