Abstract
A combined truss bridge of double bridge decks relates to a novel bridge structure and the combined truss bridge of double bridge decks consists of an upper concrete bridge deck, a steel structure web member and a lower concrete bridge deck. The upper and lower bridge decks are used for bearing the load of vehicles and are used as an upper chord part and a lower chord part to share the global stress with the global structure. The steel structure web member consists of a slant web member and a vertical web member, and combines the upper and the lower concrete bridge decks as a whole to be used for resisting the shearing force of the truss bridge. The upper concrete bridge deck and the lower concrete bridge deck in tensile areas are provided with vertically stressed steel bars or section steel. The invention, compared with traditional single bridge deck combined girder bridges, enjoys greater traffic capacity and higher traffic comfort; compared with steel truss bridges, the invention remarkably reduces steel consumption by using concrete bridge decks as compression chords, and has the advantages of low noise, easy maintenance, good durability and so on.
Description
Technical field
The present invention relates to a kind of novel bridge structure, belong to the bridge engineering field.
Background technology
Traditional steel-concrete combined bridge all adopts single bridge deck, promptly forms as the bridge floor concrete slab that uses and the plate girder or the steel truss girder that are positioned at the bottom by being positioned at top.For the compound beam by Continuous beam design, intermediate support zone plate girder or steel truss girder are in pressured state, are unfavorable for bringing into play the supporting capacity of steel.Have again,, can not satisfy the needs of transport development when number of track-lines adopts single bridge deck more for a long time along with day being becoming tight of the growth of urban traffic amount and land resources.Therefore, a kind of traffic capacity of research and design is big, stressed rationally, and the novel bridge that all has certain advantage on economy and workability has crucial meaning.
Summary of the invention
The object of the present invention is to provide that a kind of traffic capacity is big, stressed rationally, the double-deck bridge floor combined trussed girder bridge of easy construction.
Technical scheme of the present invention is as follows:
A kind of double-deck bridge floor combined trussed girder bridge, it is characterized in that: this combination truss bridge contains upper strata concrete slab 1, lower-layer concrete bridge deck 2 and is arranged on steel structure web member between the upper and lower layer concrete bridge deck, and upper and lower layer concrete bridge deck being linked to be integral body by the gusset plate 3 that winds up, lower-chord panel point plate 4 and shear connector 7, described steel structure web member is made up of perpendicular web member 5 and diagonal web member 6.
Upper strata of the present invention concrete slab 1 and lower-layer concrete bridge deck 2 adopt precast plate, superimposed sheet or cast-in-place plated construction.Be in the upper strata concrete slab of tensile region and the lower-layer concrete bridge deck and should be furnished with longitudinal stress reinforcing bar or shaped steel; Upper strata concrete slab 1 and lower-layer concrete bridge deck 2 should apply prestressing force as required to prevent concrete cracking in addition.
Technical characterictic of the present invention also is: described lower-chord panel point plate 4 is connected in the top of lower-layer concrete bridge deck 2, or is connected in the below of lower-layer concrete bridge deck 2.
The present invention has the following advantages with respect to prior art: 1. with respect to traditional single bridge deck composite beam bridge, the traffic capacity of double-deck bridge floor combined trussed girder bridge is stronger, and the sight line of levels bridge floor is all comparatively open, driving comfort level height; 2. with respect to steel truss girder bridge, the combination truss bridge utilizes concrete slab as compression boom, can significantly reduce steel using amount, have simultaneously noise low, be easy to advantages such as maintenance, good endurance.3. gusset plate is connected the steel web member with shear connector about adopting with concrete slab, has characteristics such as easy construction, simple structure.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Double-deck bridge floor combined trussed girder bridge provided by the invention is made up of upper strata concrete slab 1 and lower-layer concrete bridge deck 2 and steel structure web member, and by the gusset plate 3 that winds up, lower-chord panel point plate 4 and shear connector 7 each ingredient is linked to be integral body.Upper and lower layer concrete bridge deck both use as the bridge deck that bear vehicular load, simultaneously as trusses whole stressed (as shown in Figure 1, 2) of upper and lower string parts participation structure.Steel structure web member is made up of perpendicular web member 5 and diagonal web member 6, but also concrete perfusion in perpendicular web member and the diagonal web member is used to resist the shearing of truss bridge.Be in the upper strata concrete slab 1 of tensile region and the lower-layer concrete bridge deck 2 and should be furnished with longitudinal stress reinforcing bar or shaped steel 8 (as shown in Figure 3); Can apply prestressing force in addition as required to prevent concrete cracking.Upper strata concrete slab 1 and lower-layer concrete bridge deck 2 can adopt precast plate, superimposed sheet or cast-in-place plated construction form.
Fig. 4 is the node cross-sectional view that winds up of the present invention, the node 3 that winds up is connected in the below of upper strata concrete slab 1.The lower-chord panel point embodiment can have two kinds of forms, and a kind of is the top (shown in Figure 5) that lower-chord panel point 4 is connected in lower-layer concrete bridge deck 2, or lower-chord panel point 4 is connected in the below (shown in Figure 6) of lower-layer concrete bridge deck 2, latter's construction of being more convenient for.
