Formwork-free ultra-thick floor and construction method thereof

Abstract

The invention discloses a formwork-free ultra-thick floor which is provided with a bottom plate. The bottom plate is formed by splicing a plurality of steel plates, a plurality of steel sections are fixed to the steel plates at intervals, a first steel channel is connected between every two adjacent steel sections on each steel plate, and the first steel channels are connected to the upper portions of the steel sections; and concrete is poured on the bottom plate. In one embodiment, hanging bars are connected between the adjacent steel sections, a splicing joint between every two adjacent steel plates is covered with flat steel, and the two sides of the flat steel are welded to the corresponding steel plates. In the other embodiment, a second steel channel is welded between every two adjacent steel sections, the second steel channels are connected to the lower portions of the steel sections, and a third steel channel is welded between the steel sections on the two sides of a splicing joint of every two adjacent steel plates and connected to the upper portions of the steel sections on the two sides of the splicing joint. According to the formwork-free ultra-thick floor and a construction method thereof, the steel sections are welded to the steel plates to be used as reversed beams, so that the bearing capacity of the steel plates to loads of concrete of the ultra-thick floor is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork-free super-thick floor slab and a construction method thereof. Background technique [0002] In building construction, the pouring formwork of the floor slab generally needs to erect a support frame, and the formwork is supported by the support frame, thereby performing concrete pouring of the floor slab. However, for some ultra-thick floors with valuables, large objects, or closed spaces on the lower floor, the formwork cannot be set up or removed, that is, the support frame for the formwork cannot be erected due to the above conditions in the lower floor. , thus needing a formwork-free construction method that can bear the heavy concrete load of super-thick floor slabs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a formwork-free super-thick floor slab and its construction method, which ...

Problems solved by technology

However, for some ultra-thick floors with valuables, large objects, or closed spaces on the lower floor, the formwork cannot be set up or removed, that is, the support frame for the formwork cannot be erected due to the above conditions in the lower floor. , so a formwork-free construction method that can bear the large concrete load of the super-thick floor is required
