Abstract
The utility model discloses a steel pipe arch bridge, which comprises two piers, two cast-in-situ beams which are respectively arranged on the two piers, and a main beam. The main beam comprises a steel beam middle section and two closure sections, wherein the steel beam middle section is erected above the two piers in a straddling way and consists of a plurality of sections of steel beams which are assembled and fixedly connected together, and the two closure sections are respectively arranged on the two cast-in-situ beams. Moreover, the two enclosure sections are respectively closed and fixedly connected with the two ends of the steel beam middle section. Since the two closure sections are respectively closed and fixedly connected with the two ends of the steel beam middle section and the steel beam middle section consists of the plurality of sections of steel beams which are assembled and fixedly connected together, the steel pipe arch bridge has the advantages of less channel occupation time, high construction efficiency, low construction cost and high construction accuracy.
Description
Technical field
The utility model relates to a kind of steel pipe arch bridge.
Background technology
Existing steel pipe arch bridge comprises that two bridge piers, two arrange the girder that is welded together by many girder steels order successively at the cast-in-place beam of two bridge piers and respectively, and said girder two ends are fixed in two cast-in-place beams respectively.Because girder is to be welded together in regular turn by many girder steels, therefore need take the navigation channel for a long time, construction cost is high, and efficiency of construction is low, and construction precision is low.
The utility model content
The utility model provides a kind of steel pipe arch bridge, and it has overcome the existing existing deficiency of steel pipe arch bridge in the background technology.
The technical scheme that is adopted that the utility model solves its technical problem is:
A kind of steel pipe arch bridge; It comprises that two bridge piers (10), two arrange a cast-in-place beam (20) and the girder at two bridge piers (10) respectively; Said girder comprises that the frame that collapses arranges the closure segment (40) at two cast-in-place beams (20) respectively on two bridge piers (10) and by the affixed girder steel interlude (30) and two of multistage girder steel assembly unit; And said two closure segments (40) close up respectively and are fixed in girder steel interlude (30) two ends.
Among one preferred embodiment: it comprises arch rib; Said arch rib comprises that two are embedded in the pre-buried place of arch springing (50) that two cast-in-place beams (20) locate, two arch tube edge joint sections (60) and respectively by the affixed arch tube interlude (70) of multistage arch tube assembly unit; A said arch tube edge joint section (60) is fixed between pre-buried place of an arch springing (50) and arch tube interlude (70) one ends, and said another arch tube edge joint section (60) is fixed between the pre-buried place of another arch springing (50) and arch tube interlude (70) other end.
Among one preferred embodiment: be fixed by welding in together between said closure segment (40) and the girder steel interlude (30).
Among one preferred embodiment: said arch tube interlude (70), arch tube edge joint section (60) and the pre-buried place of arch springing (50) are fixed by welding in together.
Among one preferred embodiment: all be provided with cement board on closure segment of said girder (40) and the girder steel interlude (30).
The present technique scheme is compared with background technology, and it has following advantage: two closure segments close up respectively and are fixed in girder steel interlude two ends, and the girder steel interlude is fixed together by the assembly unit of multistage girder steel; It is few then to take the navigation channel time; Efficiency of construction is high, and construction cost is low, and construction precision is high.Arch rib comprises the pre-buried place of two arch springings, two arch tube edge joint sections and an arch tube interlude, and support strength is high, and it is few to take the navigation channel time.

Label declaration: bridge pier-10, cast-in-place beam-20, girder steel interlude-30, closure segment-40, arch springing pre-buried place-50, arch tube edge joint section-60, arch tube interlude-70.
The specific embodiment
A kind of steel pipe arch bridge is please referred to Fig. 1, and it comprises that two bridge piers 10, two arrange cast-in-place beam 20, a girder and two arch ribs at two bridge piers 10 respectively.
Said girder comprises a girder steel interlude 30 and two closure segments 40.Said girder steel interlude 30 collapses frame on two bridge piers 10 and affixed by the assembly unit of multistage girder steel.Said two closure segments 40 are arranged respectively at two cast-in-place beams 20.Said two closure segments 40 close up respectively and are fixed in girder steel interlude 30 2 ends.Be fixed by welding in together between said closure segment 40 and the girder steel interlude 30.All be provided with cement board on the closure segment 40 of said girder and the girder steel interlude 30.
Said arch rib comprises the pre-buried place of two arch springings 50, two arch tube edge joint sections 60 and an arch tube interlude 70.The pre-buried place 50 of said two arch springings is embedded in two cast-in-place Liang20Chu respectively.Said arch tube interlude 70 is fixed together by the assembly unit of multistage arch tube.A said arch tube edge joint section 60 is fixed between pre-buried place 50 of an arch springing and arch tube interlude 70 1 ends, and said another arch tube edge joint section 60 is fixed between the pre-buried place 50 of another arch springing and arch tube interlude 70 other ends.Said arch tube interlude 70, arch tube edge joint section 60 and the pre-buried place 50 of arch springing are fixed by welding in together.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented according to this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
