Abstract
The invention discloses a reinforced concrete laminated slab consisting of plate bottom steel bars, bent-up steel bars, limiting stoppers and a prefabrication layer. The reinforced-concrete laminated slab is characterized in that each limiting stopper is I-shaped and consists of an upper limiting surface, a lower limiting surface and a connector between the upper and lower limiting surfaces, the lower limiting surfaces of the limiting stoppers are positioned in the prefabrication layer, and the half parts of the bent-up steel bars are arranged in the prefabrication layer. As the laminated slab fully utilizes the functions of materials, the common stress on an adjoining face between the prefabrication layer and a cast-in-situ layer of the laminated slab is ensured, and the shearing performance of the part of the laminated slab, close to a support, is improved.
Description
Technical field
The present invention relates to the building structural member technical field, specifically belong to a kind of reinforced concrete sandwich plate.
Background technology
The reinforced concrete sandwich plate is the prefabricated and cast-in-place a kind of form of structure that combines as the part of iterative structure.Superimposed sheet is earlier laid prefabricated panel in the bottom in work progress, it is the effect of lifting plate during layer concrete on building, and then two parts concrete forms integral body and comes bearing load.It is cast-in-place that superimposed sheet design at present exists the mating face not to be equal to, and the precast plate that has is made and the construction inconvenience, even cost is higher.The present invention solves these problems preferably.
Summary of the invention
The purpose of patent of the present invention provides a kind of reinforced concrete sandwich plate, overcomes the deficiency of prior art, guarantees construction quality, meets design requirement.
Reinforced concrete sandwich plate of the present invention is like this design: said reinforced concrete sandwich plate by plate at the bottom of reinforcing bar, bent-up bar, stop and preformed layer form; Be characterized in that stop is " worker " font; By upper limit face, lower limit face; And the composition of the connector between upper limit face, lower limit face, the lower limit face of stop is arranged in preformed layer, and superimposed sheet thickness is controlled by the upper limit face of stop, the distance of lower limit face; Half is arranged on bent-up bar in the preformed layer, to strengthen being connected of in-situ layer and preformed layer.
The present invention controls prefabricated and protective layer thickness in-situ layer because prefabricated superimposed sheet plate portion increases multi-functional stop, replaces stirrup iron, strengthens the connection of overlapping layers, as shear key.According to the loading characteristic of plate, near bearing, bent half reinforcing bar at interval, strengthened the connection of levels; Strengthen shear behavior; Solved precast plate with the effective connectivity problem of cast-in-place beam.
Description of drawings
Fig. 1 is the structural representation of reinforced concrete sandwich plate of the present invention.
Wherein: 1, reinforcing bar 4, preformed layer at the bottom of stop 2, bent-up bar 3, the plate.
The specific embodiment
Below in conjunction with accompanying drawing reinforced concrete sandwich plate of the present invention is described further.
As can beappreciated from fig. 1; The reinforced concrete sandwich plate by plate at the bottom of reinforcing bar 3, bent-up bar 2, stop 1 and preformed layer 4 form; Be characterized in that stop is " worker " font, by upper limit face, lower limit face, and the connector between upper limit face, lower limit face is formed; The lower limit face of stop is arranged in preformed layer 4, and superimposed sheet thickness is controlled by the upper limit face of stop 1, the distance of lower limit face.Half is arranged on bent-up bar 2 in the preformed layer 3, to strengthen being connected of in-situ layer and preformed layer.
The present invention takes into full account the loading characteristic of plate, has made full use of the function of material, has guaranteed that the prefabricated and cast-in-place mating face of superimposed sheet is stressed jointly.Improved near the shear behavior of superimposed sheet bearing.Because it has just not only guaranteed the quality of superimposed sheet, and has had tangible economic advantages thing to the greatest extent.
