Prestressed reinforced concrete dish plate

Abstract

The invention discloses a prestress reinforced concrete dish plate in the technical field of construction materials, comprising a double-parabolic plate and a faceplate, wherein edges of both sides of the double-parabolic plate are connected with the faceplate into a whole, and both sides of the faceplate are wider than both sides of the double-parabolic plate so as to form flange girthes on both sides. In order to further reduce the consumption amount of concrete and to increase the bearing capacity, the midspan parts of the edges of both sides of the double-parabolic plate are connected with the upper surface of the faceplate, and the end-span parts at both ends of the edges of both sides of the double-parabolic plate are connected with the lower surface of the faceplate. The prestress reinforced concrete dish plate has efficient bending resistance and saves steel; under the circumstance of maintaining the bearing capacity, the consumption amount of the concrete is reduced, the self-weight of constructional members is reduced, and the cost is saved; and after the expansion and the stretch of prestress steel, the midspan is slightly arched. The prestress reinforced concrete dish plate can be used for the floor engineering of a multi-storey workshop of a factory building with larger span, and can also replace overhead simple-supported box girders of overhead high-speed railways with large broad width and inter-city light rails.

Description

technical field [0001] The invention belongs to a prefabricated part of building materials, in particular to a structure of prestressed concrete components. Background technique [0002] The traditional simply supported box girder is a box girder structure with a square or rectangular cross section, which has a large wall thickness, a large amount of concrete, and a large self-weight. At present, the common hyperbolic slabs in the construction industry have parabolic rotating surfaces, that is, the longitudinal section and cross section of the hyperbolic slabs are parabolic. or elevated structures. Contents of the invention [0003] The object of the present invention is to provide a prestressed reinforced concrete disc-shaped slab that reduces the amount of concrete and steel bars while ensuring the bearing capacity. [0004] In order to achieve the above object, the technical solution of the present invention is: a prestressed reinforced concrete disc-shaped slab, incl...
