Abstract

The invention relates to a T-shaped beam dismantling method. Fixing pieces are installed on the two sides of a damaged T-shaped beam; a bridge body between the damaged T-shaped beam and other T-shaped beams is cut, and the damaged T-shaped beam is kept stable; a stabilizing piece is installed on the side face, facing the bridge body, of the damaged T-shaped beam, the length direction of the stabilizing piece is consistent with that of the damaged T-shaped beam, and the length of the stabilizing piece is larger than or equal to that of the damaged T-shaped beam; a connecting piece is arranged on the damaged T-shaped beam, the two ends of the connecting piece are connected to the two opposite side faces of the stabilizing piece respectively, and the connecting piece abuts against the side face, opposite to the stabilizing piece, of the damaged T-shaped beam; and the damaged T-shaped beam is hoisted, and dismantling is completed. The structure stability of the damaged T-shaped beam is guaranteed, stress between the stabilizing piece and the damaged T-shaped beam can be stable and uniform in the hoisting process, lateral instability or further damage in the hoisting process is avoided, and the stability and safety of the T-shaped beam dismantling method are improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a T-beam removal method. Background technique [0002] Bridges are generally composed of four parts: superstructure, substructure, support and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles. Conventional superstructure types mainly include T-beams, small box girders, and hollow bridges. slab, continuous box girder, etc. Among them, the prestressed T-beam has been widely used in the field of highway transportation in my country because of its convenient construction, simple process, clear force, and large spanning capacity. [0003] As the national traffic flow continues to increase, higher requirements are placed on the safety of bridge structures. For some old existing structures, or damaged structures that have been destroyed, it is often faced with the problem of demolition and rec...
