Abstract
The utility model provides an enhanced type reinforced concrete laminated floor slab and belongs to the field of building structures. A prefabricated base plate of the concrete laminated floor slab consists of a reinforced concrete lower layer and a square hole ribbed concrete upper layer, wherein the reinforced concrete lower layer of the prefabricated base plate is provided with longitudinal straight steel bars and transverse saddle-shaped steel bars at intervals, and two transverse ends of two parallel steel bars of the saddle-shaped steel bars are II-shaped ends extending vertically and upward. The square hole ribbed concrete upper layer is respectively provided with longitudinal concrete ribs, transverse concrete ribs and light filling blocks in square holes formed by the longitudinal concrete ribs and transverse concrete ribs, wherein the concrete ribs are arranged at intervals. The top faces and the outer sides of two II-shaped ends of the transverse saddle-shaped steel bars expose to the upper surface and longitudinal side faces of the prefabricated base plate, are poured into cast-in-place concrete layers during concrete layer in-place pouring and form the integrated laminated floor slab with the cast-in-place concrete layers. The strength of the laminated floor slab is improved, the deformation resisting performance of the concrete laminated floor slab is improved, and the transverse bearing capacity of the concrete laminated floor slab is improved.
Description
Technical field
A kind of enhancement mode 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 cast-in-place part be connected and plate and plate between be connected and seem not enough, 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 purpose of this utility model is to provide a kind of enhancement mode reinforced concrete laminated floor slab, improves reinforced concrete slab anti-deformation, strengthens the bearing capacity of concrete folding plate floor; 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 enhancement mode 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, there are spaced longitudinally straight reinforcing bar and horizontal shape of a saddle reinforcing bar in the steel concrete lower floor of prefabricated panel, and the transverse ends of two parallel reinforcing bars of described shape of a saddle reinforcing bar is the Π shape end of stretching on vertically; Described square opening rib frame concrete upper strata has respectively interval that vertical concrete rib and horizontal concrete rib are set, and the light filling piece in the square opening of vertical, horizontal concrete rib formation; Cast-in-place one deck layer of concrete and form laminated floor slab at the construction field (site) after prefabricated panel moulding.
The height at described horizontal shape of a saddle reinforcing bar ΠXing two ends is higher than the height of prefabricated panel.
In the horizontal concrete rib on described square opening rib frame concrete upper strata, be provided with rib frame reinforcing bar.
A kind of enhancement mode reinforced concrete laminated floor slab of the utility model, is provided with horizontal shape of a saddle reinforcing bar in the steel concrete lower floor of its prefabricated panel, and laterally the height at the ΠXing two ends of shape of a saddle reinforcing bar higher than the height of prefabricated panel; On square opening rib frame concrete upper strata, there is respectively interval that vertical concrete rib and horizontal concrete rib are set, and have light filling piece in its square opening that longitudinally, laterally concrete rib forms; Prefabricated panel after moulding, outside the upper surface that the end face at the ΠXing two ends of described horizontal shape of a saddle reinforcing bar and outside are emerging in prefabricated panel and longitudinally side, when cast-in-situ concrete layer, built and entered in cast-in-situ concrete layer, with cast-in-situ concrete formable layer one laminated floor slab, therefore, the utility model has strengthened this laminated floor slab self intensity, improves reinforced concrete slab anti-deformation, strengthens the bearing capacity of concrete folding plate floor.
