Abstract
The utility model relates to a straight-rib honeycomb reinforced concrete composite floor slab and belongs to the field of building structures. The slab is composed of a prefabricated base plate and a cast-in-place concrete layer. The prefabricated base plate is composed of a reinforced concrete lower layer and a square hole rib frame concrete upper layer. Vertical steel bars, transverse steel bars and transverse steel plates are arranged on the reinforced concrete lower layer of the prefabricated base plate, the transverse steel bars are saddle-shaped steel bars, n-shaped ports stretching upwards are formed in the transverse two ends of the two parallel steel bars, and the transverse steel plates are symmetrically arranged at two vertical ends of the prefabricated base plate. Vertical concrete ribs and transverse concrete ribs are arranged on the square hole rib frame concrete upper layer at intervals respectively, and light filling blocks formed in square holes of the vertical concrete ribs and the transverse concrete ribs are arranged on the square hole rib frame concrete upper layer. The composite floor slab is formed by arranging the cast-in-place concrete layer on the prefabricated base plate in a pouring mode. The weight of the slab is reduced, stress and deformation resistance of the slab in the transverse span are improved, and meanwhile the slab is good in heat insulation sound insulation performance, can be produced in factories, and is high in production efficiency and convenient to construct.
Description
Technical field
A kind of straight rib honeycomb reinforced concrete laminated floor slab of the utility model, belongs to building structure field.
Background technology
At present, the concrete floor in building field is divided into Bars In Poured Concrete Slab, precast plate and traditional laminated floor slab three types.The cast-in-place part of tradition laminated floor slab and the advantage that pre-erection combines Bars In Poured Concrete Slab and precast plate, in engineering, application is more and more extensive, but its pre-erection and the deficiency that seems being connected of cast-in-place part, the common practice is in prefabricated panel colligation or welds overhanging reinforcing bar, with the bonding strength between reinforcement plate and plate, but the prefabricated panel of prior art and cast-in-situ concrete layer to be connected operation complicated, increased site operation difficulty and engineering time.
Utility model content
The object of utility model is to provide a kind of straight rib honeycomb reinforced concrete laminated floor slab, improves reinforced concrete slab anti-deformation, strengthens the bearing capacity of concrete folding plate floor, to meet the demand of long span building; And possess good insulation, soundproof effect and be suitable for efficient industrial rate and produce.
The utility model is achieved through the following technical solutions:
A kind of straight rib honeycomb reinforced concrete laminated floor slab of the utility model, by prefabricated panel and cast-in-situ concrete layer, formed, prefabricated panel is comprised of steel concrete lower floor and square opening rib frame concrete upper strata, in prefabricated panel steel concrete lower floor, there are longitudinal reinforcement, transverse reinforcement and lateral type steel plate, this transverse reinforcement is shape of a saddle reinforcing bar, the transverse ends of its two parallel reinforcing bars is the port Π shapes that protrude upward, and described lateral type steel plate is symmetricly set on longitudinal two ends of prefabricated panel; There are respectively spaced vertical concrete rib and horizontal concrete rib in described square opening rib frame concrete upper strata, and the light filling piece arranging in the square opening forming in vertical, horizontal concrete rib; After prefabricated panel moulding at the construction field (site), cast-in-situ concrete layer and form laminated floor slab.
The described lateral type steel plate that is symmetricly set on the longitudinal two ends of steel concrete lower floor is L-type shape steel plate, plays the effect of lateral support in floor system.
Described horizontal shape of a saddle reinforcing bar has the height at the ΠXing two ends that protrude upward higher than prefabricated panel.
The longitudinal two ends of described prefabricated panel are concrete enclosing end.
There is symmetrical connection contract mouth the longitudinal both sides of the edge of described prefabricated panel.
