Description
Technical Field
The utility model relates to a cast-in-situ pavement structure.
Background
At present, the conventional pavement structure with the bridge precast slabs has the outstanding characteristic of rapid construction, but according to engineering practical experience, as the pavement slabs are precast, the joints are more, so that water is often accumulated in the pavement, and the pavement prefabrication degree is low and the construction is more complicated under the condition that the bridge deck pavement is widened. If the cast-in-situ pavement slab is adopted, the lower clearance of the slab is low, and the problems of formwork supporting, difficult formwork removing and the like exist, so that the conventional cast-in-situ formwork cannot be used.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, and provides the cast-in-situ pavement structure with reasonable structural design, which well solves the problems of difficult formwork supporting and removing of the cast-in-situ pavement plate, and has convenient construction and strong applicability.
The utility model solves the problems by adopting the following technical scheme: a cast-in-situ pavement structure comprises a railing base, a middle pavement beam and an outer pavement beam; the railing base, the middle road beam and the outer road beam are sequentially arranged; the method is characterized in that: the concrete slab also comprises fixing pegs, profiled steel sheets and concrete slabs; the profiled steel sheet is fixed on the railing base, the middle road beam and the outer road beam by adopting fixing studs; the concrete slab is paved on the profiled steel sheet; the railing base, the middle road beam, the outer road beam and the concrete slab are poured into a whole.
The railing base, the middle road beam and the outer road beam are all made of concrete materials.
The utility model also comprises a pedestrian railing, wherein the pedestrian railing is arranged on the railing base.
The outer side of the outer side road beam is paved with a bridge deck.
The profiled steel sheet of the utility model is a galvanized steel sheet.
The brand of the profiled steel sheet is S250.
The fixing peg adopts a round head peg.
The fixing stud is arranged at the groove of the pressed steel plate.
Compared with the prior art, the utility model has the following advantages and effects:
1) The utility model adopts cast-in-situ concrete plates and profiled steel plates to form a combination, and then the combination is poured into a whole with the pavement beam. The practical problems of the cast-in-situ pavement plate such as formwork supporting and difficult formwork removing are well solved, the bearing capacity of a conventional concrete slab can be improved, the plate thickness is optimized, the practical problems that the clearance is low and the conventional cast-in-situ formwork cannot be arranged under the existing cast-in-situ pavement structure are effectively solved, and the cast-in-situ pavement plate is free from demoulding and convenient to construct.
2) Compared with the conventional precast slab of the concrete pavement, the bearing capacity of the precast slab of the concrete pavement is improved, and the thickness of the concrete slab and the concrete consumption can be effectively reduced.
