Abstract

The invention discloses an elevated steel-concrete composite beam, comprising a cross beam and a pier column. The cross beam is fixedly connected to the top of the pier column, and both sides of the bottom of the inner wall of the cross beam are slidably connected to a transmission seat. A sliding seat is slidably connected to the left side, and steel beams are fixedly connected to the tops of the two sliding seats. A concrete slab is fixedly connected between the tops, a rectangular groove is formed at the bottom of one of the transmission seats and the top of the other transmission seat, and the two transmission seats are slidably connected to the bottom of the inner wall of the beam in a symmetrical dislocation. In the invention, the two sides of the bottom of the concrete slab are subjected to force at the same time, no longer descending, the force is decomposed and converted, the uneven stress on the concrete slab is reduced, the stability of the overall structure of the concrete beam is improved, and the main column is straight. Rod shape, vertical and horizontal force, no bending phenomenon.

Description

technical field [0001] The invention relates to the technical field of composite beams, in particular to an elevated steel-concrete composite beam. Background technique [0002] Steel-concrete composite beam is a new type of structure developed on the basis of steel structure and concrete structure. It mainly resists the lifting and relative sliding at the interface between the steel beam and the concrete flange plate by setting shear connectors (bolts, channel steel, bending bars, etc.) work together. [0003] At present, the existing elevated steel-concrete composite beams fix the steel beam and the concrete slab together through shear connectors. When one side of the top of the concrete slab is inclined, if it cannot be adjusted and reset, the long-term stress will lead to steel Cracks occur at the connection between the beam and the concrete slab, which is more likely to cause fracture for a long time. The pillars at the bottom of the concrete slab may be bent under pr...
