Embodiment Construction

[0036] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0037] The specific embodiment one of the assembled steel-concrete composite beam of the present invention, such as figure 1 As shown, the assembled steel-concrete composite beam includes a steel box beam and a concrete panel 1, the steel box beam constitutes a supporting beam, the steel box beam includes a steel box beam body and an upper flange roof 3, the steel box beam body is U-shaped, and the concrete The face plate 1 is poured on the lower end of the upper flange roof plate 3 to ensure that the upper flange roof plate 3 and the concrete face plate 1 are poured densely and the connection is firm. There are shear nails 15. The shear nails 15 constitute a shear connector. The shear nails 15 can resist the horizontal shear force on the negative bending moment and ensure the stability of the composite beam; the two sides of the steel box girder are cor...

Abstract

The invention relates to an assembled steel concrete composite beam and a forming method thereof. The assembled steel concrete composite beam comprises a concrete panel and a support beam which are arranged along the vertical direction; the support beam is provided with an upper flange top plate; the concrete panel and the upper flange top plate are formed by casting; and the upper flange top plate is positioned at the upper part of the concrete panel. The casting position of the concrete panel is moved to the lower end of the upper flange top plate from the upper end of the upper flange top plate, so it is guaranteed that the upper flange top plate and the concrete panel are cast compactly and connected firmly, meanwhile, the upper flange top plate bears the stress of a hogging moment area, the material utilization rate is increased, and cost is saved.

Description

technical field [0001] The invention relates to an assembled steel-concrete composite beam and a forming method thereof. Background technique [0002] The steel-concrete composite beam is a transverse load-bearing member that is composed of steel beams and concrete slabs connected together by shear-resistant parts to jointly bear the force. It has the advantages of high bearing capacity, high rigidity, good seismic performance, small section size of components and convenient construction. [0003] At present, the commonly used steel-concrete composite beams of urban viaducts are mainly composite steel plate bridges and composite steel box bridges. Because of its simple structure, composite steel plate bridges were first developed and applied. The early composite steel plate bridges set many beams, horizontal supports and vertical supports between side-by-side steel plate girders, and welded many transverse stiffeners on the web. It is small, resulting in a large number of ...
