Description
Technical Field
The utility model relates to rail transit facilities, in particular to a prestressed concrete roof structure system applied to an overhead station.
Background
In the construction of urban rail transit in China, lines in suburban areas are mostly constructed in the form of erecting ground viaducts, and corresponding stations are constructed in the form of ground overhead stations. At present, steel structure roofs are mostly adopted for the elevated station platform layers. Compared with a concrete structure, the steel structure roof has the advantages of large span, no need of arranging middle upright posts in an orbit area, high construction speed and the like, but the steel structure roof has poor structural durability, and some steel structure roofs of overhead stations are put into use for about ten years and are severely corroded.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a prestressed concrete roof structure system applied to an elevated station, so as to effectively improve the durability of the roof structure of the elevated station, lighten the dead weight of the roof structure and increase the using span of the roof structure.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model discloses a prestressed concrete roof structure system applied to an elevated station, which is characterized in that: the reinforced concrete roof comprises reinforced concrete upright posts, prestressed concrete beams, roof structure side beams, roof middle longitudinal beams and reinforced concrete roof plates; the reinforced concrete upright posts are longitudinally arranged at two lateral sides of the station platform layer at intervals; the prestressed concrete beams are longitudinally arranged at intervals and cross the whole platform layer, and two ends of each prestressed concrete beam are fixedly connected with the tops of the reinforced concrete columns on the same side respectively; the roof structure side beams longitudinally extend, are arranged at the tops of the reinforced concrete columns on the same side and are fixedly connected with the reinforced concrete columns; the middle longitudinal beams of the roof are transversely arranged at intervals and longitudinally extend to be fixedly connected with each prestressed concrete beam; the reinforced concrete roof slab is poured on the top surface of a grid-shaped structure formed by prestressed concrete beams, roof structure side beams and roof middle longitudinal beams.
The prestressed concrete roof slab has the advantages that the prestressed concrete roof slab structure has good durability, and meanwhile, the span of the beam is relatively large, and an intermediate upright post is not required to be arranged; the structure is simple, and the construction is convenient.
