Ribbed prestressed thin plate as well as casting mold and casting method thereof

Abstract

The invention relates to the technical field of concrete products and discloses a ribbed prestressed thin plate as well as a casting mold and a casting method thereof. The ribbed prestressed thin plate comprises a bottom plate and multiple rib plates arranged on the bottom plate, wherein the bottom plate is internally provided with a criss-cross bottom plate reinforcing mesh; the rib plates are internally provided with rib plate rebars. Since the bottom plate is internally provided with the criss-cross bottom plate reinforcing mesh and the rib plates are internally provided with the rib plate rebars, the strength of the rib plates and the bottom plate can be enhanced, a formed PK prestressed laminated concrete slab has relatively high strength, deformation and even breakage are avoided, the engineering equality is improved, and unnecessary losses are omitted. By virtue of adopting the casting mold and casting method of the ribbed prestressed thin plate provided by the embodiment of the invention, casting of the ribbed prestressed thin plate can be realized; furthermore, the casting mold of the rib plate adopts full bolt connection, so that rapid formwork supporting can be achieved, the production efficiency is improved, and batched prefabrication production of the rib plates can be realized.

Description

Technical field [0001] The invention relates to the technical field of concrete products, in particular to a ribbed prestressed thin slab and its pouring mold and pouring method. Background technique [0002] PK prestressed concrete composite slab is a single-span slab or continuous slab composed of prefabricated ribbed prestressed thin slabs and cast-in-situ concrete composite layers, followed by non-prestressed perforated steel bars and broken-line anti-cracking steel bars. [0003] The ribbed prestressed thin slab includes a concrete bottom plate and a plurality of concrete ribs arranged on the concrete bottom plate. The ribbed prestressed thin slab itself is thin, not strong enough, and the bending rigidity is small. After forming the PK prestressed concrete composite slab, the concrete ribs and the concrete bottom plate are subjected to certain pressure, and they are compressed during actual transportation, hoisting and installation. Collision may cause deformation or even br...

Problems solved by technology

The ribbed prestressed thin slab itself is thin, not strong enough, and the bending stiffness is small. After forming the PK prestressed concrete laminated slab, the concrete ribs and the concrete bottom slab bear a certain pressure, and are squeezed during actual transportation, hoisting and installation. Collision, prone to deformation or even breakage, causing unnecessary losses
