Problems solved by technology

Among them, corrugated steel web prestressed concrete composite box girder sections are made by prefabrication technology, and construction is carried out by assembly technology, which has good development prospects because of its simple construction process, less on-site workload, and shortened construction period. The poor performance of the joint parts during assembly construction, and the large impact of assembly errors on the joint parts restrict the popularization and application of the assembly process.

Embodiment Construction

[0018] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose of the invention, the specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] Such as figure 1 , figure 2 The schematic diagram of the prefabricated assembled structure of corrugated steel webs of the present invention includes a reinforced concrete top plate 1, a corrugated steel web 2, a reinforced concrete bottom plate 3, and a prefabricated segment 6, wherein a plurality of corrugated steel webs 2 are arranged on the reinforced concrete top plate 1 and the reinforced concrete floor 3 form a prefabricated segment 6 . Two adjacent prefabricated segments 6 are fixed by concrete hinges 4 and connectors 5 .

[0020] Wherein the concrete hinge 4 is a combined structure, and a protrusion 31 is provided on the same side of the reinforced c...

Abstract

The invention discloses a corrugated steel web prefabricated assembly, comprising prefabricated segments. Each two adjacent prefabricated segments are connected with each other through concentrate hinges and a connecting piece, and the prefabricated segments are formed by corrugated steel webs between a reinforced concrete top plate and a reinforced concrete bottom plate in parallel. The corrugated steel web prefabricated assembly is fixed through bolts, the outer sides of bending parts are subjected to groove welding treatment, and welding and bolt connection are combined, so that the rigidity of connecting parts is improved, and the integrality of prefabricated segment units is enhanced; as welding treatment is combined with bolt connection, the influence to the connecting parts of eccentric load, caused by installation errors in a construction process, is reduced, and the strength of the connecting parts is improved; as steel plates are inserted into the inner sides of the connecting parts, gap error caused by improper installation in a construction process can be absorbed, the connecting parts are compact, stress is reasonable, and a construction effect is guaranteed.

Description

technical field [0001] The invention relates to a structural accessory of a steel-concrete composite box girder, in particular to a prefabricated assembled structural part of a corrugated steel web. Background technique [0002] The corrugated steel web prestressed concrete composite box girder bridge is a kind of steel-concrete composite structure. In this structure, the corrugated steel web replaces the concrete web of the usual prestressed concrete box girder, so that the box girder Reduced self-weight and dead load internal force have become a major feature of prestressed concrete bridge structures with corrugated steel webs. Due to the wrinkle effect of the corrugated steel web, the concrete roof and bottom plate bear the bending moment while the wave box steel web bears the shear force during bending. Due to the limited space for prestressed beam distribution on the top and bottom slabs, external cables are used, which is another characteristic of prestressed concrete...
