Abstract

The invention discloses a one-way prefabricated hollow slab with a gradient cross section for a composite slab of a set block building, and belongs to the technical field of fabricated buildings. Theproblems that the using amount of a cast-in-place concrete laminated layer required by an existing prefabricated slab for the composite slab is large, a support needs to be arranged during construction, and stress is not reasonable enough are solved. The one-way prefabricated hollow slab comprises a midspan area and support areas located at the two ends of the midspan area; the bottom face of themidspan area and the bottom faces of the support areas are located on the same horizontal surface, and the thickness of the support areas is smaller than that of the midspan area; a plurality of through holes are machined in the span direction of the midspan area of the hollow slab; the top face of each support area is provided with a plurality of first through grooves in the span direction of themidspan area; a plurality of U-shaped grooves are machined in the two ends of the upper part of the midspan area correspondingly; the opening ends of the U-shaped grooves are located at the two endsin the span direction of the midspan area correspondingly; and the multiple U-shaped grooves are evenly distributed, and the lower parts of the U-shaped grooves communicate with the through holes.

Description

technical field [0001] The invention relates to a unidirectional prefabricated slab for a composite building panel, in particular to a unidirectional prefabricated hollow panel with a gradient cross section for a composite panel of a building block, and belongs to the technical field of prefabricated buildings. Background technique [0002] According to the construction method, the floor can be divided into three types: integral type, assembled type and assembled integral type. The prefabricated integral floor takes the advantages of the integral floor and the prefabricated floor, and has the advantages of high overall rigidity, good seismic performance, simple construction, and shortened construction period. The concrete laminated slab is an assembled integral floor formed by pouring a layer of cast-in-place concrete on the prefabricated slab. According to the stress situation, it can be divided into a primary stressed laminated slab and a secondary stressed laminated slab....
