Description
Technical field
This utility model is related to building element technical field, more particularly to a kind of reinforced for green building
Concrete folding plate.
Background technology
At present, the reinforced concrete floor of domestic employing has cast-in-situ floor and a precast floor slab, cast-in-situ floor good integrity, but
Need live formwork, then casting concrete, construction period difficulty is big, template loss is big, high cost, and precast floor slab is not required to scene
Mould, short construction period, low cost, but prefabricated components, from great, lift difficult, and component splicing position is also easy to produce crack, globality
Difference.
Superimposed sheet refers to that one kind, by the use of precast concrete base plate as template, pours overlapping layers thereon, pouring simultaneously
As the superstructure of an overall work after the completion of building.
At present, do not slot in the side of existing superimposed sheet, and that docks two superimposed sheets, and the docking in two superimposed sheets
During place's casting concrete, the amount of concrete pouring seldom, makes the adhesion between new-old concrete not enough it is difficult to form shearing resistance
Key.
How to solve the striving direction that this technical problem has become those skilled in the art.
Content of the invention
The purpose of this utility model is：The existing two superimposed sheets docking solving easily produces crack, the skill of poor performance
Art problem, this utility model provides a kind of reinforced concrete folding plate for green building.
This utility model specifically employs the following technical solutions to achieve these goals：
A kind of reinforced concrete folding plate for green building, connects including superimposed sheet substrate and cast-in-place concrete
Part, superimposed sheet substrate includes top plate and lower plywood, and described top plate upper surface is provided with least one groove, described lower floor
The upper surface of plate is provided with shear reinforcement, and the bottom of described shear reinforcement is embedded in lower plywood, and the top of shear reinforcement is higher than
The upper surface of superimposed sheet embeds in top plate, and about superimposed sheet substrate, two ends are provided with groove, adjacent two pieces of superimposed sheet substrates
Butt joint edge formed interface slot, be provided with left and right two ends in top plate and extend some precast reinforced of top plate, precast reinforced
Two ends are provided with thread head or the elbow of anchoring, and the elbow of described thread head or anchoring is located in interface slot, and described shows
Pouring concrete connector is coordinated with interface slot.
Further, described groove is one of dovetail groove, arcuate groove, rectangular channel.
Further, described some precast reinforced horizontal spaced set.
Further, described shear reinforcement includes a depression bar and at least two groups stirrups being arranged on depression bar support,
Described stirrup supports as V-type or U-shape structure, and the open end that stirrup supports has anchoring crotch respectively.
Further, described depression bar is one of strip steel, steel pipe, C-type steel, U-steel or round steel.
Further, top plate and the thickness proportion of lower plywood are 3:1.
The beneficial effects of the utility model are as follows：
1st, this utility model structure is simple, opens up groove side in the side of existing concrete prefabricated panel, in adjacent coagulation
Casting concrete in interface slot after native prefabricated panel docking, forms shear key, improves the jail of adjacent superimposed sheet binding site
Solidity, superimposed sheet substrate is threaded connection from each other with superimposed sheet substrate or elbow anchoring is it is ensured that be connected precisely reliable, subtracts
The flatness error of little flooring, thus do not need re-modulation low-intensity mortar carry out floating make up a deficiency deviation, increase overlapping
Shearing strength between plate and the cast-in-place concrete layer in later stage and saving of work and time.
2nd, the superimposed sheet of top plate top-slitting, the later stage, groove was interior again places steel bar girder or passive support,
Casting concrete again in groove, makes support and superimposed sheet pour formation one, is divided into two steps and completes, reduce process equipment cost
Low, also improve production efficiency simultaneously.
