Abstract
The utility model discloses a cellular ribbed frame composite floor slab, and belongs to the field of building structures. According to the design, the composite floor slab is composed of a prefabricated base plate and a cast-in-place slab, the prefabricated base plate is composed of a reinforced concrete lower layer and a straight rib concrete upper layer, prestressed reinforcements are arranged in parallel at intervals on the reinforced concrete lower layer in the longitudinal direction of the prefabricated base plate, a row of long circular through holes are longitudinally formed at intervals in the straight rib concrete upper layer, concrete rib columns are vertically arranged at intervals in all the long circular through holes, light filler is arranged inside spacings of the concrete rib columns of all the long circular through holes, and transverse prestressed reinforcements arranged at intervals are arranged on the long circular through holes in the longitudinal direction. According to the cellular ribbed frame composite floor slab, the stress and deformation resistance on the transverse span of the floor slab are enhanced, the self weight of the floor slab is lowered, the floor slab is suitable for meeting the requirement of a long-span building floor slab, meanwhile, thermal insulation performance and sound insulation performance are good, the floor slab is suitable for factorization high efficiency production, and site operation is convenient.
Description
Technical field:
A kind of honeycomb rib of the utility model frame laminated floor slab, belongs to building structure field.
Background technology:
At present, building floor comprises Bars In Poured Concrete Slab, precast plate and traditional superimposed sheet, and Bars In Poured Concrete Slab globality and anti-seismic performance are good, but needs a large amount of templates, time-consuming taking a lot of work.Precast plate does not need template, and assembling speed is fast, but the globality of structure and shock resistance are poor.Tradition superimposed sheet pre-erection and cast-in-place part have merged respectively the advantage of above two plates, but pre-erection is unreliable with being connected of cast-in-place part, and dead load is large, and waste material.
Utility model content:
The object of utility model is to provide a kind of honeycomb rib frame laminated floor slab, alleviates floor deadweight, strengthens floor at the stressed and deformation resistance of horizontal span, to be applicable to the needs of long span building floor, meanwhile, this floor insulation, sound insulation, and be suitable for the production of efficient industrial rate.
The utility model is realized by following scheme:
A kind of honeycomb rib of the utility model frame laminated floor slab, by prefabricated panel and Bars In Poured Concrete Slab, formed, described prefabricated panel is comprised of steel concrete lower floor and straight rib concrete upper strata, it is longitudinal that prefabricated panel is pressed by described steel concrete lower floor, parallel interval arranges prestressed reinforcement, in straight rib concrete upper strata, the circular long through-hole in interval that has a row longitudinally to arrange, the concrete rib post that has vertical spacing at each shape circle long through-hole, in the clearance space of the concrete rib post of each circular long through-hole, there is light filling thing, longitudinally circular long through-hole has spaced transverse prestressed reinforcing steel bar.
There is longitudinal reinforcement on described straight rib concrete upper strata.
The two ends of the longitudinal circular long through-hole in described straight rib concrete upper strata are the solid blind end of concrete.
The longitudinal both sides of the edge of described prefabricated panel are provided with and connect contract mouth.
The utility model has strengthened the stressed and deformation resistance of floor at horizontal span, has alleviated floor deadweight, is applicable to the needs of long span building floor, and meanwhile, insulation, sound-proofing is good, and is suitable for efficient industrial rate and produces, and site operation is convenient.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
Fig. 2 is the preformed hole schematic diagram that the utility model is prepared straight rib concrete upper strata;
Fig. 3 is that the utility model is prepared interval filler schematic diagram in the elongated circular hole in straight rib concrete upper strata.
The specific embodiment:
Below in conjunction with accompanying drawing, implementation process of the present invention is described.
Superimposed sheet of the present invention is comprised of prefabricated panel and cast-in-situ concrete layer, prefabricated panel is comprised of steel concrete lower floor 1 and straight rib concrete upper strata 2, first, longitudinal by prefabricated panel, parallel interval arranges prestressed reinforcement 1-1, builds and prepares steel concrete lower floor 1, the surface of Zai steel concrete lower floor 1 is by the mould of setting, make straight rib concrete upper strata 2: longitudinal reinforcement 2-1 is set, adopt current in the industry method reserved circular long through-hole 3 in concrete upper strata 2, in circular long through-hole 3, put into filler 4, reserved top upright opening 5-1 above circular long through-hole 3, perpendicular to the reserved transverse holes 6 of reserved upright opening 5-1 direction, and put into transverse reinforcement 6-1 in reserved transverse holes 6, concreting from upright opening 5-1 again, concrete upper strata 2 has been built and form rib post 5, the two ends of the longitudinal circular long through-hole in straight rib concrete upper strata are the solid blind end of concrete, in the longitudinal both sides of the edge of prefabricated panel, be provided with and connect contract mouth.
Above-mentioned prefabricated panel prepared by batch production is transported to scene, builds at the construction field (site) overlapping layers 7 and forms superimposed sheet.
