Description
Technical field
The present invention relates to a kind of bridge, particularly to a kind of multilayer deck rail-cum-road bridge beam.
Background technology
Track traffic is the important component part of urban public transport, generally use bridge mode cross over rivers,
Mountain valley.For investment reduction, when span of bridge is more than 300m, generally employing and urban road system is built jointly
Form, to make full use of bridge location resource.Conventional arrangement form is that urban road is arranged with layer with track, or
Person is more than urban road and track, lower leaf layout, and urban road is on upper strata, and track is in lower floor；
During upper and lower layered arrangement, owing to the width of roadway of urban road is commonly greater than track width, girder is normal
Using inverted trapezoidal cross section, the power transmission of the type cross section is not direct, and structure stress efficiency is low；Meanwhile, clean by track
The empty impact required, inverted trapezoidal lower floor bridge floor design requirement spatial altitude is the biggest, and space availability ratio is low,
Cause waste of material.
It is thus desirable to a kind of novel rail-cum-road bridge beam, it is possible to be effectively improved bridge structure by force efficiency, have
Effect utilizes the space of structure sheaf, and then reduces Engineering Overall cost.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of multilayer deck rail-cum-road bridge beam, it is possible to effectively
Improve bridge structure efficiency, effectively utilize structure space.
The multilayer deck rail-cum-road bridge beam of the present invention, including Steel Truss Beam with supported by Steel Truss Beam and along steel
The rail layer of the parallel longitudinal setting of girder truss and track layer, described rail layer is positioned at above the layer of track；
Further, described Steel Truss Beam is parallel main truss structure, and described bridge is cross-section for rectangular configuration；
Further, described rail layer and track layer include steel cross bridge floor board and crossbeam, described rail respectively
The track for track traffic it is provided with on channel layer floorings；
Further, it is vertically arranged with for strengthening track bridge floor between floorings and its crossbeam of described rail layer
Longeron and Research on Open Stiffener, be vertically arranged with to remain silent between floorings and its crossbeam of described track layer and put more energy into
Rib；
Further, described track layer is the two-layer up and down of parallel longitudinal setting, and described girder is double-deck main truss knot
Structure；
Further, described upper and lower two-layer track is one-way trip road；
Further, the current direction rightabout each other in described upper and lower two-layer track；
Further, described Research on Open Stiffener is plain plate, described in ribbed stiffener of remaining silent be U-shaped rib.
Beneficial effects of the present invention: the multilayer deck rail-cum-road bridge beam of the present invention, uses rectangular multilayer truss
Form, structure power transmission is direct, and structure efficiency is high；Track is arranged in the superiors of bridge, it is possible to make rail
Channel layer is not by structure space limitation in height；Driveway is arranged in below rail layer, can not increase truss height overall
Under degree, effectively utilize structure sheaf space；Meanwhile, if multilamellar truss form applies to Mountainous City bridge, energy
Enough bring and compare original truss form more preferable landform adaptation ability；And then reduce Engineering Overall cost.Accompanying drawing
Explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings
Fig. 1 is the cross-section of bridge structural representation of the present invention.
Detailed description of the invention
Fig. 1 is the cross-section of bridge structural representation of the present invention, as shown in the figure: the multilayer deck of the present invention is public
The dual-purpose bridge of rail, including Steel Truss Beam 1 with supported by Steel Truss Beam 1 and along the parallel longitudinal setting of Steel Truss Beam
Rail layer 2 and track layer 3, described rail layer 2 is positioned at above track layer 3.In the present embodiment, described
Steel Truss Beam 1 is parallel main truss structure, and described cross-section of bridge is rectangular configuration；Space availability ratio is high, knot
Structure is more firm, and stress is in hgher efficiency, and stability is higher.
In the present embodiment, described rail layer 2 and track layer 3 include steel cross bridge floor board and crossbeam respectively
(8,81,82)；From heavy and light, can participate in common stress as a part for girder, ultimate bearing capacity is big, can
To alleviate deadweight significantly, increase span；It is provided with the rail for track traffic on described rail layer floorings
Road 4；Owing to the width of rail layer bridge floor is consistent with the width of track layer bridge floor, therefore track can make full use of
The space on upper strata, can arrange a plurality of track according to bridge deck width and its carrying, increase the utilization of structure
Rate.
In the present embodiment, it is vertically arranged with for strengthening between floorings 2 and its crossbeam 8 of described rail layer
The longeron 7 of track bridge floor and Research on Open Stiffener, longeron 7 can be arranged according to the quantity of track 4, typically
One track arranges two longerons 7 for 4 times and strengthens, vertical between the floorings of track layer Yu its crossbeam (81,82)
To being provided with ribbed stiffener 6 of remaining silent；In the present embodiment, described track layer 3 is up and down the two of parallel longitudinal setting
Layer, described in set a roof beam in place as double-deck main truss structure；Bridge floor is arranged and is vertically divided into three layers, and track is upper strata, and track is
In, lower two-layer；Track is arranged in the superiors of bridge, it is possible to make rail layer not by structure space height
Limit；Driveway is arranged in below rail layer, can effectively utilize structure sheaf under not increasing truss total height
Space；Double-deck main truss structure is the two-layer main couple arranged along same plane, this bilayer main truss structure include and
Top boom 11 that track cross beam 8 connects and the middle chord member 12 that is connected respectively with track lower and upper cross-member (81,82)
With lower boom 13, between chord member, it is cross-linked to form, by web member (14,15), the node being positioned on chord member, this
Structure is prior art, therefore here is omitted its detailed mounting structure.
In the present embodiment, described upper and lower two-layer track is one-way trip road；Vehicular traffic tissue is according to traffic
Current direction is individually arranged in one layer of bridge floor, it is to avoid the current risk that the two-way traffic of same layer bridge floor is brought,
Improve bridge floor traffic efficiency.
In the present embodiment, the current direction rightabout each other in described upper and lower two-layer track；Improve bridge floor to pass through
Efficiency, meets the demand that traffic is current.
In the present embodiment, described Research on Open Stiffener 7 is plain plate；Can also be inclined bulb steel plate, bulb steel
Plate, L-type rib, inverted T shape rib etc., described in remain silent ribbed stiffener 6 for U-shaped rib, it is also possible to for flute profile rib, V
Shape rib and Y shape rib etc., but affected by track layer floorings thickness, preferably U-shaped rib, and this structure is more
Adapt to the thickness of floorings.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although
With reference to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that,
Technical scheme can be modified or equivalent, without deviating from technical solution of the present invention
