Steel-wood combined bridge structure with pored steel plate connecting piece

Abstract

The invention discloses a steel-wood combined bridge structure with a pored steel plate connecting piece. The steel-wood combined bridge structure comprises an upper bridge structure, a lower bridge structure, a wood bridge panel formed by splicing a plurality of rectangular wood plates, and a bottom bearing structure located right below the wood bridge panel, wherein a plurality of pored steel plates are sandwiched in the wood bridge panel; the bottom bearing structure comprises a plurality of lower longitudinal beams distributed on a same plane and a plurality of lower cross beams distributed on a same plane; the pored steel plates and the lower longitudinal beams are identical in number, and the plurality of pored steel plates are respectively fastened right above the plurality of longitudinal beams; and the plurality of rectangular wood plates and the plurality of pored steel plates are assembled into a whole through transversely distributed prestress steel bundles, and the plurality of pores steel plates and the prestress steel bundles jointly bear the shear force and the lift force among the steel-wood structure. The steel-wood combined bridge structure disclosed by the invention has the advantages of simple structure, convenience for construction, definite stress, reliability in connection and good use effect, and various defects of the traditional steel-wood combined bridge can be overcome while the spanning capability of the wood structure bridge is increased.

Description

technical field [0001] The invention belongs to the technical field of bridge construction engineering, and in particular relates to a steel-wood composite bridge structure provided with perforated steel plate connectors. Background technique [0002] The steel-wood composite structure bridge is a bridge structure that uses a combination of steel girders and wooden bridge decks. It has the advantages of light weight, fast construction speed, good durability, and high degree of industrialization. It is currently a bridge form that has attracted much attention in the bridge industry. one. The stress-laminated wooden bridge deck introduces prestressing technology into the wooden bridge deck to improve its integrity, and has higher bearing capacity and better performance than ordinary screw-laminated bridge decks. Therefore, the steel stress laminated wooden bridge deck combined bridge structure can give full play to the advantages of steel structure and wooden structure, high ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a steel-wood composite bridge structure with perforated steel plate connectors in view of the above-mentioned deficiencies in the prior art. Good, while increasing the spanning capacity of wooden bridges, it can effectively solve the defects of existing steel-wood composite bridges, such as a large number of connecting components, inconvenient construction, and low construction efficiency.
