Whole collapse preventing high and large formwork supporting system

Abstract

The invention provides a whole collapse preventing high and large formwork supporting system and belongs to the technical field of building template supporting. The whole collapse preventing high and large formwork supporting system consists of a dual-function structural system and a single-function structural system. The dual-function structural system comprises orthogonally grid-shaped stress walls mainly serving as main vertical stress structures and arranged in a crossed mode, a main keel, an auxiliary keel and a connecting beam, wherein the main keel, the auxiliary keel and the connecting beam serve as horizontal stress members. Each pieces of grid-shaped stress wall consists of two rows of thick vertical rods, cross rods connected with the thick vertical rods and vertical diagonal bracings arranged in planes where each row of thick vertical rods, and a multiple-layer structure is formed in the vertical direction and fixed with stress columns with permanent structures through horizontal restraints and fasteners. The single-function structural systems is arranged among the grid-shaped stress walls, conventional design is adopted, the diagonal bracings are omitted, and two systems are connected through cross rods. The dual-function structural system can independently bear a part of load borne by the single-function structural system under the condition that the single-function structural system is invalid, and whole structural collapse is avoided.

Description

technical field [0001] The invention belongs to the technical field of building formwork support, and in particular relates to an overall collapse-proof tall formwork support system. Background technique [0002] The tall formwork support system refers to the formwork support system with a formwork support height of more than 8m for concrete members on the construction site. The fastener-type formwork support system is the main formwork support system in my country. The structural system is derived from the external scaffolding. Its basic force-bearing units and nodes are common to the external scaffolding. The arrangement of components is not much different from the external scaffolding. However, the force characteristics and restraint methods of the formwork support and the external scaffold are completely different. Applying the structural system of the external scaffold leads to an unreasonable structural system. Once the vertical pole loses stability, the fasteners coll...

Problems solved by technology

However, the force characteristics and restraint methods of the formwork support and the external scaffold are completely different. Applying the structural system of the external scaffold leads to an unreasonable structural system. Once the vertical pole loses stability, the fasteners collapse and the structure collapses as a whole, leaving nowhere for the construction workers to escape. , easily causing mass casualties
