The superimposed sheet consists of a prefabricated bottom plate and a cast-in-place concrete layer, wherein the prefabricated bottom plate consists of a lower reinforced concrete layer and an upper hemispheric honeycomb hole type rib frame concrete layer; the associated continuous hemispheric rib frame is positioned between adjacent hemispheric honeycomb holes in the upper hemispheric honeycomb hole type rib frame concrete layer; a heat insulating layer is filled in the hemispheric honeycomb holes; after the prefabricated bottom plate is molded; and a layer of concrete is subjected to cast-in-place to form the superimposed sheet on the upper hemispheric honeycomb hole type rib frame concrete layer on a construction site. The prestressed reinforced concrete superimposed sheet is uniform in force transmission in each direction and stable in structure, enhances the bidirectional stress capability of the superimposed sheet and the anti-shearing performance of a superposed surface, improves the anti-seismic property of the superimposed sheet, meets the requirement on large-span building, reduces the self-weight, and has a good effect on heat preservation, heat insulation and noise reduction.

Description

Hemispherical honeycomb hole type rib frame prestressed reinforced concrete superimposed sheet

Technical field

Hemispherical honeycomb hole type rib frame prestressed reinforced concrete superimposed sheet of the present invention belongs to building structure section bar field.

Background technology

Along with a large amount of appearance of highrise building, and the variation of form of structure, large-span space structure becomes a kind of demand.Along with the increase of building height, alleviate member dead weight and also become more and more important.Existing superimposed sheet is applicable to little span frame construction basically, and can not solve the problem of thermal insulation, thickness of slab and from great, the shear resistance of superposed surfaces is also limited.

Summary of the invention

The purpose of this invention is to provide a kind of hemispherical honeycomb hole type rib frame prestressed reinforced concrete superimposed sheet, can effectively limit the relative slippage of superposed surfaces, strengthen its shear resistance, the honeycomb rib increases the pipeline of power, make it have good anti-seismic performance, isolation layer in the hole improves the thermal insulation anti-acoustic capability of plate, and alleviates deadweight, satisfies the long span building structure to the demand of high-performance floor.

Hemispherical honeycomb hole type rib frame prestressed reinforced concrete 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 and hemispherical honeycomb hole type rib frame concrete upper strata, and in described steel concrete lower floor, along becoming plate width parallel interval that steel bar stress is set, on steel bar stress, perpendicular separation is connected with distribution reinforcement; On described hemispherical honeycomb hole type rib frame concrete upper strata, it is related continuous hemispherical rib frame between its adjacent hemispherical honeycomb hole, be filled with the thermal insulation separation thermosphere in described hemispherical honeycomb hole, after the prefabricated panel moulding, at the construction field (site), in prefabricated panel hemispherical honeycomb hole type rib frame concrete upper strata, cast-in-place one deck layer of concrete and form superimposed sheet.

The hemispherical honeycomb hole of described prefabricated panel is spherical supine hemispherical.

The hemispherical honeycomb hole of described prefabricated panel is perpendicular to the steel concrete lower floor of prefabricated panel.

The hemispherical honeycomb hole type rib frame concrete upper strata of described prefabricated panel is the foaming cement concrete layer.

Described steel bar stress is by prestressed reinforcement, and perhaps prestressed reinforcement and plain bars form.

hemispherical honeycomb hole type rib frame prestressed reinforced concrete superimposed sheet of the present invention, by using prestressed reinforcement to make superimposed sheet produce appropriate antiarch value, can delay the development in crack at the bottom of plate, improve the bending rigidity of prefabricated units, in whole superimposed sheet design, in the situation that do not affect structure stress, the deadweight of taking the continuous rib frame of honeycomb hole type to alleviate superimposed sheet, utilize hemispherical hole space, filling heat insulating wall is with the thermal insulation of lifting superimposed sheet and the performance of noise reduction, continuous rib shelf structure, the Path of Force Transfer of superimposed sheet is increased, each is even to power transmission, therefore structure is more stable, promote anti-seismic performance and the application life of superimposed sheet, satisfy the long span building structure to the demand of high-performance superimposed sheet.And prefabricated units of the present invention can serve as template in construction uses, and avoids a large amount of formwork workloads, improves efficiency of construction.

The specific embodiment

Below in conjunction with description of drawings implementation process of the present invention.

Superimposed sheet of the present invention is comprised of prefabricated panel and cast-in-situ concrete layer, prefabricated panel is comprised of steel concretelower floor 1 and hemispherical honeycomb hole type rib frame concreteupper strata 2, become plate width parallel interval thatsteel bar stress 4 is set on described steel concretelower floor 1. edges, on describedsteel bar stress 4, perpendicular separation is connected withdistribution reinforcement 5; On described hemispherical honeycomb hole type rib frame concreteupper strata 2, its honeycomb hole K is hemispherical-shaped aperture, and this hemispherical honeycomb hole is spherical supine first spherical pore, and its adjacent cell is related continuous hemispherical rib frame between the hole; Be filled with thermalinsulation separation thermosphere 6 in described hemispherical honeycomb hole K, after the prefabricated panel moulding, be transported to job site assembling, a cast-in-place layer concrete 3 on the honeycomb hole type rib frame concreteupper strata 2 of prefabricated panel namely forms superimposed sheet.

During the steel concretelower floor 1 of preparation prefabricated panel, formed by prestressed reinforcement and plain bars along thesteel bar stress 4 that becomes the setting of plate width parallel interval, first prestressed reinforcement is carried out stretch-draw, two kinds of spacing of reinforcements arrange, namely build preparation steel concretelower floor 1; After steel concretelower floor 1 builds and completes, immediately in steel concretelower floor 1, be intervally arranged and fixing hemisphere heat insulating material, concreting in the gap of hemisphere heat insulating material again, institute's concreting layer all standing hemisphere heat insulating material forms the hemisphere rib frame layer ofconcrete 2 that is filled with thermalinsulation separation thermosphere 6 in the hemispherical honeycomb hole; So far, namely form prefabricated panel; Reach the intensity of regulation when prefabricated panel after, it is transported to job site assembling and cast-in-situ concrete layer 3, namely forms withupper strata 2 combinations of honeycomb hole type rib frame concrete and form the one overlapping layers.
