Abstract
The utility model discloses a waterproof cover plate used for a seam between two longitudinal beams of a bridge. The waterproof cover plate is arranged right above the seam between the parallel longitudinal beams of a bridge and is characterized in that the waterproof cover plate is composed of an upper layer and a lower layer, the upper layer is a concrete layer, the lower layer is a steel plate, one side of the waterproof cover plate is fixed on the bridge, and the other side of the waterproof cover plate is vertically supported on the bridge. The waterproof cover plate used for the seam between two longitudinal beams of the bridge can be applied to the waterproofing of bridges, in particular to the waterproofing of the seam between the parallel longitudinal beams of the bridge and the seam between the longitudinal beams of an elevated railway station bridge and has the advantages of being simple and rapid in construction, low in construction cost and post maintenance cost, good in waterproof performance and good in economic benefit.
Description
Technical field
The utility model relates to the bridge engineering field, is specifically related to a kind of waterproof cover for bridge longitudinal beam seam place.
Background technology
Existing bridge cover plate all is block cover plate, and is prefabricated by bridge cover plate mould in factory earlier, is transported on the bridge and installs.Existing bridge cover plate can be divided into the steel concrete cover plate according to material, RPC cover plate, steel plate cover plate; But all there is certain defective in these three kinds of cover plates in construction and use:
1, steel concrete and RPC cover plate all are to use mould prefabricated, and prefabricated cover plate is vertical, lateral dimension in 1m, increases as if size usually, the corresponding increase of weight, the on-the-spot relatively difficulty of installing has the space between the prefabricated cover plate, does not possess the function of waterproof.
2, steel concrete and RPC cover plate, because of the spatial constraints of cover plate below, formwork erection, form removal difficulty do not possess condition cast-in-place on the bridge, can not form continuous cover slip, therefore do not possess the function of waterproof.
3, steel deck-plate after on-the-spot welding, can form continuous cover slip, tentatively possess the function of waterproof, but the workload of on-the-spot welding is very big, and speed of application is slower; When steel deck-plate need bear big load, must the steel plate of putting more energy into be set below cover plate, can satisfy stressed requirement, structure more complicated, the workload increasing of welding.
Summary of the invention
The purpose of this utility model is to be the prior art deficiency, and a kind of waterproof cover for bridge longitudinal beam seam place is provided, and has the excellent waterproof function.
For solving the problems of the technologies described above, a kind of waterproof cover for bridge longitudinal beam seam place that the utility model is designed, this waterproof cover be arranged on parallel bridge longitudinal beam seam place directly over, described waterproof cover is divided into two-layer up and down, described upper strata is layer of concrete, described lower floor is steel plate, and described waterproof cover one side is fixed on the bridge, and the opposite side vertical support is on bridge.
Further, described waterproof cover is the continuous seamless cover plate.
Again further, described waterproof cover both sides are provided with baffle plate.
Again further, described waterproof cover one side is fixed on the bridge by crab-bolt.
Again further, the thickness of described layer of concrete is 0.3 ~ 0.7m, and the thickness of described steel plate is 0.1 ~ 0.3m.
Advantage of the present utility model is:
1, the utility model waterproof cover is the continuous seamless cover plate, does not have the space in the middle of the cover plate, can not leak, seep water.
2, as template, building site cast-in-situ concrete forms layer of concrete to the utility model with steel plate, and is convenient for production quick, need not form removal, and therefore structure of the present utility model should be simple relatively, and the difficulty of construction is low, speed is fast, and cost is relatively low, can effectively promote.
3, the utility model waterproof cover is divided into two-layerly up and down, and under layer of concrete and the steel plate acting in conjunction, this waterproof cover should possess the intensity that the load that bears with it is complementary, and can bear effect load in the above, the situation that ftractures, destroys do not occur.
4, the utility model waterproof cover should utilize crab-bolt to be fixed on the bridge, makes the waterproof cover can the side direction landing.During variations in temperature, waterproof cover is answered retractable, and temperature deformation can not be restricted.
5, the utility model can be applied to the bridge waterproof, the particularly waterproof at the longitudinal beam seam place between two parallel bridges, and the waterproof at overhead station bridge longitudinal beam seam place; Easy construction is quick, and is cheap, and the later maintenance expense is low, and good water-proof effect has good economic benefit.
Description of drawings
Fig. 1 is for being used for the waterproof cover at bridge longitudinal beam seam place;
Fig. 2 is vertical view of the present utility model
Among the figure, 1. upper strata, 2. lower floor, 3. baffle plate, 4. bridge, 5. crab-bolt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, so that those skilled in the art understand.
Embodiment 1
As shown in the figure, a kind of waterproof cover for bridge longitudinal beam seam place that the utility model is designed, this waterproof cover be arranged on parallel bridge longitudinal beam seam place directly over, described waterproof cover is divided into two-layer up and down, described upper strata 1 is layer of concrete, described lower floor 2 is steel plate, and described waterproof cover one side is fixed on the bridge 4, and the opposite side vertical support is on bridge 4.
Described waterproof cover is the continuous seamless cover plate.Described waterproof cover both sides are provided with baffle plate 3.Described waterproof cover one side is fixed on the bridge 4 by crab-bolt 5.
The thickness of described layer of concrete is 0.3 ~ 0.7m, and the thickness of described steel plate is 0.1 ~ 0.3m.
The steel plate of lower floor 2 and baffle plate 3 are all selected the Q235 steel plate for use in the present embodiment, the layer of concrete on upper strata 1 is selected fibrous concrete for use, the load that the thickness of lower floor's 2 steel plates and the layer of concrete on upper strata 1 bear according to cover plate calculates to be determined, steel plate and fibrous concrete can effectively prevent the cover plate cracking.
Although above-described embodiment has been made detailed description to the utility model; but it only is the utility model part embodiment; rather than whole embodiment; people can also obtain other embodiment according to present embodiment under without creative prerequisite, these embodiment belong to the utility model protection domain.
