Embodiment Construction

[0023] A novel hollow composite panel of the present invention, such as figure 1 , 2 , 3, 4, and 5, including a flat steel plate 1, a plurality of perforated steel plates 2 and a plurality of steel pipes 3, each perforated steel plate 2 is vertically welded on one side of the flat steel plate 1 in parallel, and the plurality of steel pipes 3 are respectively pierced in each corresponding round hole of each perforated steel plate 2, and the steel pipe 3 is welded together with each corresponding round hole of each perforated steel plate 2, so that the flat steel plate 1, the plurality of perforated steel plates 2 and the plurality of The steel pipes 3 are welded together to form a hollow slab support 4, on which the lightweight aggregate concrete 5 is poured, finally forming a steel plate-light aggregate concrete hollow composite slab. Lightweight aggregate concrete 5 is a kind of concrete formed by using ceramsite as aggregate.

[0024] During processing, first weld the perf...

Abstract

The invention discloses a novel hollow composite slab, which comprises a flat steel plate, a plurality of holed steel plates, and a plurality of steel pipes, the holed steel plates are parallel and are vertically welded on one plane of the flat steel plate, the plurality of steel pipes respectively pass through corresponding round holes of the holed steel plate and are welded with the round holes, the flat steel plate, the plurality of holed steel plate, and the plurality of steel pipes combine into a hollow slab support, and the hollow slab support is poured with light aggregate concrete to finally form the steel plate-light aggregate concrete hollow composite slab. The novel hollow composite slab of the invention has light weight, convenient construction, higher strength and rigidity, and better bearing performance, can be widely applied to the bridge slabs of new bridges and house buildings, the basement top board or room floor, and can be also applied to the bridge slab replace and maintenance engineering.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a hollow composite plate. Background technique [0002] The composite panels used in civil engineering are generally steel plate-concrete composite panels or hollow panels. Steel plate-concrete composite slab refers to pouring concrete directly on the steel plate, and then through certain measures to make the two closely combined to form a floor slab or bridge deck that works together. The composite slab does not need formwork and erection of temporary supports in the construction project. It is convenient, but the self-weight of the steel plate-concrete composite slab is too large, so it is not suitable for bridge decks and floor slabs with large spans. In engineering practice, in order to reduce the self-weight of bridge decks and floors, hollow slabs are often used, but the strength and mechanical performance of hollow slabs are poor. Contents of the invention [0003] The...
