Background technology
The vehicle of straddle-type monorail transportation system rides on elevated-beam walks, bridge is both as the load-bearing bridge span structure generally speaking, again as the track of vehicle operating and guiding, be subjected to the restriction of straddle type vehicle gauge size, the rail beam section width is 0.85m, therefore, the general prestressed concrete simply supported beam of striding footpath 20～22m that adopts of rail beam is as the standard spanning.Standard is striden the footpath beam can be prefabricated in factory or base, and set up at the scene, and speed of application is fast, and construction technology is simple, and beam physique amount ensures that easily low cost is applicable to most of line conditions.But for the special sector that is subjected to the restriction of local landform and leaping over obstacles, as require single track bridge necessary to cross over situations such as existing urban road and corresponding intersection system, do not allow bridge pier is set in the middle of road, and the necessary rail beam spanning structure that adopts large span, owing to be subjected to the restriction of cross dimensions, adopt the Technological Economy of prestressed concrete beam formula bridge span structure unreasonable, the steel work rail beam becomes inevitable choice, therefore needs a kind of large-span steel rail beam of specialized designs.
The utility model content
Technical problem to be solved in the utility model provides a kind of straddle-type monorail transportation system large-span steel rail beam, strides the footpath and can reach 30～80m, and be easy to make and on-the-spot splicing, reduces the interference of construction period to existing road.
The technical scheme that its technical problem that solves the utility model adopts is: the large-span steel rail beam of straddle-type monorail transportation system of the present utility model, comprise two girders that direction across bridge is provided with at interval, it is characterized in that: what described girder adopted is the girder steel of box section structure, and the bottom of two girders connects as one by sway bracing.
In technique scheme, described girder is assembled by at least two sections butt joints.
The beneficial effects of the utility model are, adopt the form of structure of two girders of straddle type and the flat down structure of connection in length and breadth, stride the footpath and can reach 30～80m, and can make in factory's segmentation, on-the-spot splicing, have strength of materials height, segmental structure short from heavy and light, convenient transportation, site operation phase, existing road is disturbed little, quality advantage such as assurance easily.

Fig. 2 is the vertical view (part) of straddle-type monorail transportation system large-span steel rail beam.
Component shown in the figure, toponym and pairing mark: girder 10, top board 11, longitudinal stiffener 11a, base plate 12, web 13, web 14, midfeather 15a, midfeather 15b, horizontal midfeather 15c, diaphragm 16, guide rail 17, stable orbit 18, horizontal baffle 19, sway bracing 20, crossbeam 21, flat connection 22.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, straddle-type monorail transportation system large-span steel rail beam of the present utility model, comprise two girders 10 that direction across bridge is provided with at interval, what described girder 10 adopted is the girder steel of box section structure, and the bottom of two girders 10 connects as one by sway bracing 20.For ease of making, transport, lifting, vertically butt joint is assembled by at least two sections for described girder 10.The utility model adopts the form of structure of two girders of straddle type and the flat down structure of connection in length and breadth, box section structure lateral stiffness and antitorque moment of inertia are bigger, stride the footpath and can reach 30～80m, and can make in factory's segmentation, on-the-spot splicing, have strength of materials height, segmental structure short from heavy and light, convenient transportation, site operation phase, existing road is disturbed little, quality advantage such as assurance easily.
With reference to Fig. 1, the main body of described girder 10 is welded by the web 13,14 of top board 11, base plate 12 and both sides.Top board 11 is a running face, and guide rail 17, stable orbit 18 vertical intervals are welded on the web 13,14 of both sides.Top board 11, base plate 12 are the structure that the box structure body is mainly resisted moment of flexure, especially top board, directly bear wheel load, take all factors into consideration top board 11, base plate 12 thickness to be defined as 28mm, and web 13,14 thickness are defined as 12mm.
Have horizontal reinforcement and vertical reinforcement in the girder 10.With reference to Fig. 1, described horizontal reinforcement is the diaphragm 16 that is provided with to the interval along along bridge.Described vertical reinforcement comprises twice midfeather 15a, 15b that is provided with at interval along direction across bridge and the horizontal midfeather 15c that is positioned at girder (10) top, and the longitudinal stiffener 11a that is provided with at interval along the longitudinal centre line of top board 11, longitudinal stiffener 11a and top board 11 soffits, diaphragm 16 welding, the spacing between the two adjacent longitudinal stiffener 11a is 250～300mm.Along bridge to, load on girder 10 top boards 11 is passed to longitudinal stiffener 11a by top board 11, pass to diaphragm 16 by longitudinal stiffener 11a again, so diaphragm 16 is equivalent to the resiliency supported of longitudinal stiffener 11a, the drift when having reduced the span of longitudinal stiffener 11a and pressurized unstability.At direction across bridge, the last bottom flange acting in conjunction of the steel case beam in diaphragm 16 and the effective width is equivalent to the i beam of a upper limb pressurized.
