Embodiment Construction

[0024] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the corrugated steel bottom plate-concrete composite beam includes: corrugated steel bottom plate 1, concrete plate 2, shear nails 3, stirrups 4 and longitudinal steel bars 5; corrugated steel bottom plate 1 is located at the lower edge of the corrugated steel bottom plate-concrete composite beam , set shear nails 3 on the upper surface of corrugated steel base plate 1, stirrups 4 and longitudinal steel bars 5 are bound to each other to form a steel mesh, and concrete slab 2 is poured on the upper edge of the corrugated steel base plate 1, wrapping the shear nails 3, hoop 4 and longitudinal reinforcement 5.

[0025] The corrugated steel bottom plate 1 bears the tensile stress of the lower edge under the bending action, instead of the tensile steel bars, the corrugated steel bottom plate 1 can be used as a formwork when pouring the concrete slab 2, which reduces the construction workload. , the c...

Abstract

The invention discloses a corrugated steel baseplate and concrete composite beam which comprises a corrugated steel baseplate, a concrete plate, shear nails, stirrups and longitudinal steel bars. The shear nails are welded to the upper surface of the corrugated steel baseplate; a reinforcing mesh composed of the stirrups and the longitudinal steel bars is placed over the corrugated steel baseplate and staggered with the shear nails; the concrete plate is arranged on the corrugated steel baseplate in a pouring mode, and the shear nails and the reinforcing mesh are wrapped in the concrete plate; the width of a bridge can be increased by transversely arranging a plurality of the corrugated steel baseplate and concrete composite beams in parallel. According to the corrugated steel baseplate and concrete composite beam, the mechanical properties of the concrete beam can be improved, the durability and reliability of a component are improved, the engineering cost is saved, the construction period is shortened, the construction procedure is simple, the construction efficiency is high, and the corrugated steel baseplate and concrete composite beam can be applied to medium and small span bridges.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a corrugated steel bottom plate-concrete composite beam for bridge engineering. Background technique [0002] In municipal and highway construction, bridge structures with reasonable stress, easy construction and good economy are required. Steel-concrete composite beams are a type of bridge superstructure that meets the requirements. Commonly used medium- and small-span steel-concrete composite beams include steel plate-concrete composite beams and steel box-concrete composite beams. The construction process is simpler than that of concrete beams, but there are still some shortcomings: For example, steel plate-concrete composite beam bridges need to be constructed of concrete. The bridge deck is set up with formwork, or prefabricated concrete slabs are used, which requires more construction procedures and higher requirements for construction equipment; steel box-concr...
