Description
Technical field
The utility model relates to a kind of Steel Bridge Deck constructing structure, is specifically related to a kind of large-span steel box girder bridge floor paving structure.
Background technology
Steel Bridge Deck construction is different from general highway asphalt structure, it directly acts on steel structure panel, in existing structure, there is in inner bottom part steel work distortion service life, corrosion, Steel Bridge Deck separates with laying layer, the phenomenons such as pavement cracking, its reason is, it is unreasonable to be on the one hand that internal steel structure is set up force structure, the structure design of laying layer does not have for the buffering of stress and removes, and causes under high temperature, wet weather, and the stress of generation is concentrated, partial fracture, and then cause overall quality problems.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, provides a kind of and can effectively solve the large-span steel box girder bridge floor paving structure that steel box girder bridge face structural instability, stress cannot remove.
For achieving the above object, the technical scheme of taking is:
A kind of large-span steel box girder bridge floor paving structure, comprise the main girder steel that is arranged on both sides, steel case beam top, laterally fixedly set up the diaphragm between main girder steel, and main girder steel is parallel and set up the longitudinal reinforced rib between diaphragm, and be arranged on the steel plate of diaphragm and longitudinal reinforced rib top and the layer of mating formation, described diaphragm and longitudinal reinforced rib form fenestral fabric, and on described diaphragm, offer the groove of setting up longitudinal reinforced rib, described longitudinal reinforced rib coupling is placed in described groove, described diaphragm is the font of falling T, described longitudinal reinforced rib is fluted body, the dual-side of longitudinal reinforced rib is outward-dipping, the described layer of mating formation comprises the anticorrosion waterproofing course setting gradually from bottom to top, the bi tumenf orr oad layer that rubber asphalt cushion coat and abrasion resistance are good.
Between described main girder steel and diaphragm, adopt and set up rear bolt and be fixedly connected with, between described diaphragm and longitudinal reinforced rib, adopt after setting up and be welded and fixed and be connected.
Described anticorrosion waterproofing course, for steel plate is carried out after frosted, sprays the zinc-plated metal material layer that waits of establishing at surface of steel plate.
Adopt technique scheme, obtained beneficial effect is:
The utility model is by the problem and shortage to existing existence, by the design steel work lower support structure of rationalizing, and lay the water resistant of layer, anticorrosive, buffering removes stress, make it can in high temperature, wet environment, further obtain the guarantee of quality, for the design of steel work, make it can ensure stressed even and better dissipation of ferees, make it can ensure that effective prestress discharges for the design of several importance of laying layer.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of diaphragm and longitudinal reinforced rib.
Sequence number in figure: 1 is that main girder steel, 2 is that diaphragm, 3 is that longitudinal reinforced rib, 4 is that steel plate, 5 is that anticorrosion waterproofing course, 6 is that rubber asphalt cushion coat, 7 is that bi tumenf orr oad layer, 8 is that groove, 9 is bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Referring to Fig. 1, Fig. 2, a kind of large-span steel box girder bridge floor paving of the utility model structure, comprise the main girder steel 1 that is arranged on both sides, steel case beam top, laterally fixedly set up the diaphragm 2 between main girder steel 1, and main girder steel 1 is parallel and set up the longitudinal reinforced rib 3 between diaphragm 2, and be arranged on the steel plate 4 of diaphragm 2 and longitudinal reinforced rib 3 tops and the layer of mating formation, described diaphragm 2 forms fenestral fabric with longitudinal reinforced rib 3, and on described diaphragm 2, offer the groove 8 of setting up longitudinal reinforced rib 3, described longitudinal reinforced rib 3 couplings are placed in described groove 8, described diaphragm 2 is the font of falling T, described longitudinal reinforced rib 3 is fluted body, the dual-side of longitudinal reinforced rib 3 is outward-dipping, the described layer of mating formation comprises the anticorrosion waterproofing course 5 setting gradually from bottom to top, the bi tumenf orr oad layer 7 that rubber asphalt cushion coat 6 and abrasion resistance are good.
Between described main girder steel 1 and diaphragm 2, adopt and set up rear bolt 9 and be fixedly connected with, between described diaphragm 2 and longitudinal reinforced rib 3, employing is welded and fixed and is connected after setting up, described anticorrosion waterproofing course 5, for steel plate 4 is carried out after frosted, sprays the zinc-plated metal material layer that waits of establishing on steel plate 4 surfaces.
The utility model is by the problem and shortage to existing existence, by the design steel work lower support structure of rationalizing, and lay the water resistant of layer, anticorrosive, buffering removes stress, make it can in high temperature, wet environment, further obtain the guarantee of quality, for the design of steel work, make it can ensure stressed even and better dissipation of ferees, make it can ensure that effective prestress discharges for the design of several importance of laying layer.
