Abstract
The utility model provides a large-span plate girder bridge frame and relates to a plate girder bridge frame. The large-span plate girder bridge frame solves the problem that existing bridge bodies are of concrete reinforcement structures and are large in self weight and high in cost, and the concrete reinforcement structures are not suitable for building of a large-span bridge. The large-span plate girder bridge frame comprises two main steel girders, a steel frame bottom beam frame and a plurality of arm plates. The two main steel girders are parallel to each other, opposite faces of two main steel girder web plates are connected with the plurality of arm plates, the arm plates are of right trapezoid structures, and the steel frame bottom beam frame is arranged between the two main steel girders, is in mechanical connection with the main steel girders through the arm plates and is formed by beams and longitudinal beams by welding. The distance between every two adjacent arm plate on the same main steel girder web plate is 10m, a bridge floor is laid on the steel frame bottom beam frame, and the distance between the two main steel girders is 5-8m. The large-span plate girder bridge frame has the advantages of being small in self weight, low in cost and particularly suitable for building of the large-span bridge.
Description
Technical field
The utility model relates to a kind of plate girder bridge framework, is specifically related to a kind of large span plate girder bridge framework, belongs to the bridge construction technical field.
Background technology
Bridge is a kind of macrostructure thing that is used for leaping over obstacles, and definite saying so crossed over the natural cover for defense (for example river, valley, straits etc.) or artificial barrier (speedway for example with traffic route (for example highway, railway, water channel etc.) or other facilities (for example pipeline, cable etc.).Railway line) structure.The purpose of bridge is to allow people, automobile, train or steamer to pass barrier.
At present, at the bridge that uses in the existing building, the body of a bridge all adopts the concrete reinforcement structure, from great, and the cost height, when span during greater than 50m, above-mentioned bridge structure is also inapplicable.
The utility model content
The purpose of this utility model is all to adopt the concrete reinforcement structure in order to solve the existing bridge body of a bridge, from great, and the cost height, and can't be applicable to the problem of wide span bridge building, and then a kind of large span plate girder bridge framework is provided.
The technical solution of the utility model is: a kind of large span plate girder bridge framework comprises two main girder steels, steelframe bottom girder frame, a plurality of upper arm plates, described two main girder steels be arranged in parallel, be connected with a plurality of upper arm plates on the opposite face of two main steel beam web plates, upper arm plate is ladder structure of right angle, steelframe bottom girder frame is arranged between two main girder steels, and set up mechanical connection by upper arm plate and main girder steel, described steelframe bottom girder frame is welded together to form by crossbeam and longeron, distance between two adjacent upper arm plates on the same main steel beam web plate is 10 meters, bridge floor is laid on the steelframe bottom girder frame, and the distance between two main girder steels is 5 meters to 8 meters.
Described main girder steel is i iron, is connected with a plurality of ribs on the web outside face of i iron.
Between adjacent two ribs of web homonymy, be connected with reinforcing bar.
Described reinforcing bar is right-angled intersection and arranges.
The utility model compared with prior art has following effect: the advantage of large span plate girder bridge framework of the present utility model is that deadweight is little, and cost is low, is particularly useful for wide span bridge building.Large span plate girder bridge frame strength height of the present utility model in addition, the wind resistance shock resistance is strong, easy construction.
Description of drawings
Fig. 1 is overall structure figure of the present utility model.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1, a kind of large span plate girder bridge framework of present embodiment comprises two main girder steels 1, steelframe bottom girder frame 2, a plurality of upper arm plates 3, described two main girder steels 1 be arranged in parallel, be connected with a plurality of upper arm plates 3 on the opposite face of two main girder steel 1 webs, upper arm plate 3 is ladder structure of right angle, steelframe bottom girder frame 2 is arranged between two main girder steels 1, and set up mechanical connection by upper arm plate 3 and main girder steel 1, described steelframe bottom girder frame 2 is welded together to form by crossbeam 2-1 and longeron 2-2, distance between two adjacent upper arm plates 3 on same main girder steel 1 web is 10 meters, bridge floor 6 is laid on the steelframe bottom girder frame 2, and the distance between two main girder steels 1 is 5 meters to 8 meters.Described main girder steel 1 is i iron, is connected with a plurality of ribs 4 on the web outside face of i iron.Between adjacent two ribs of web homonymy, be connected with reinforcing bar 5.Described reinforcing bar 5 is right-angled intersection and arranges.
