Abstract
The utility model discloses a sandwiched ribbed prestressed concrete superposed floor, comprising a ribbed prestressed concrete bottom plate, a warmth-keeping plate and superposed layer concrete, wherein the floor is formed by splicing a plurality of ribbed prestressed concrete bottom plates and subsequently pouring superposed layer concrete; a rectangular or round hole is arranged in the rib of the ribbed prestressed concrete bottom plate; a shearing force connecting part is arranged on the top of the rib of the ribbed prestressed concrete bottom plate; warmth-keeping plates with the height the same as that of the rib are arranged at two sides of the rib of the ribbed prestressed concrete bottom plate; transverse reinforcements extending out of the plate side of the ribbed prestressed concrete bottom plate are overlapped with one another, thus forming a certain overlapping length; longitudinal constructional reinforcements are arranged between the spliced seams formed by two adjacent rows of ribbed prestressed concrete bottom plates; the constructional reinforcements are arranged on the upper part of the transverse reinforcements; hoisting formworks are arranged at the spliced seams between the plates; a concrete layer with a certain thickness is poured on the plate surface and the spliced seams between the plates are filled, thus realizing the sandwiched prestressed concrete ribbed superposed floor with the span of 12 meters.
Description
Technical field:
The utility model relates to the realm of building construction, specifically refers to a kind of sandwich prestressed concrete with ribbing ± superimposed superstructure.
Background technology:
Reinforced concrete sandwich floor prestressed concrete plate with ribbing commonly used is assembled now, this floor rigidity is big, easy construction, have hole on the rib, be combined with cast-in-situ concrete after the assembly unit, but floor spiced precast prestressed concrete plate length is restricted, because deadweight is bigger, cause amount of deflection bigger behind the concreting, make the span of laminated floor slab also be restricted.The sound-insulating effect of present reinforced concrete sandwich superstructure neither be fine.
Summary of the invention:
The purpose of this utility model is to provide a kind of sandwich prestressed concrete with ribbing for building superimposed superstructure.The purpose of this utility model is achieved like this, the superimposed superstructure of a kind of sandwich prestressed concrete with ribbing, comprise prestressed concrete base plate with ribbing, warming plate and overlapping layers concrete, floor is formed by polylith prestressed concrete base plate with ribbing and warming plate splicing after-pouring overlapping layers concrete.Rib areas at both sides at prestressed concrete base plate with ribbing is placed warming plate, and the thickness of warming plate is identical with the height of prestressed concrete base plate rib with ribbing, and warming plate has strengthened the sound-insulating function of superimposed superstructure greatly.The rib top of prestressed concrete base plate with ribbing is provided with the shear connector of some, and shear connector can increase the shear resistance of superposed surfaces, and then strengthens the integral working that superimposed building is somebody's turn to do.
Have circular or square hole on the rib of prestressed concrete base plate with ribbing, horizontal connecting reinforcement is stretched out in the base plate both sides.Have hole on the rib of prestressed concrete base plate with ribbing, when some prestressed concrete base plate intercostal with ribbing of laminated floor slab was not provided with warming plate, the concrete column that forms in the hole after building the overlapping layers concrete had strengthened the integral working of superposed surfaces shear behavior and laminated floor slab greatly.There is certain distance between adjacent two prestressed concrete base plates with ribbing, form piece, mould is hung in the edge joint position setting, prestressed concrete base plate with ribbing will stretch out horizontal connecting reinforcement by the base plate both sides and splice at edge joint position, if transverse reinforcement is longer, can up curve and be not less than 90 degree bendings, vertically dispose one or more distributing bar at piece, superstructure is by the stressed formation bidirectional stress of the prestressed reinforcement plate in horizontal connecting reinforcement and the prestressed concrete base plate with ribbing, the supporting capacity of more effective performance superstructure.
Rib on the prestressed concrete base plate with ribbing is rectangle or T type, and the rib on the prestressed concrete base plate with ribbing is single rib or two rib.The existence of rib has increased the area of the rigidity and the superposed surfaces of prestressed concrete base plate with ribbing, can increase the span of prestressed concrete base plate with ribbing, prevents that prestressed concrete base plate with ribbing from damaging at stacking, transportation and hoisting process.The increase of superposed surfaces area helps strengthening the adhesive property that forms the back New-old concrete at the superimposed superstructure of integral body.
The shear connector on prestressed concrete base plate rib with ribbing top is a shaped steel.Build the overlapping layers concrete on prestressed concrete base plate with ribbing and warming plate, tamp the piece that forms between plate and plate, concrete floating back in top layer forms the superimposed superstructure of sandwich prestressed concrete with ribbing.

Fig. 2 is sandwich another embodiment of prestressed concrete overlapped slab with ribbing for building
Fig. 3 is another embodiment of architecture interlayer prestressed concrete overlapped slab with ribbing
Fig. 4 is another embodiment of architecture interlayer prestressed concrete overlapped slab with ribbing
Fig. 5 is overlapped into the floor slab structure schematic diagram for the sandwich prestressed concrete overlapped slab with ribbing of Fig. 1
The specific embodiment:
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, this sandwich prestressed concrete overlapped slab with ribbing for building, by prestressed concrete base plate 1 with ribbing, overlapping layers concrete 6 is formed, the rib top of prestressed concrete base plate 1 with ribbing is provided with the shearing connecting piece 5 of some, transverse reinforcement 3 is stretched out on the both sides of prestressed concrete base plate 1 with ribbing, transverse reinforcement 3 can up bend, prestressed concrete base plate with ribbing disposes the distributing bar 8 at longitudinal prestressing muscle 7 and rib top, after prestressed concrete ± base plate 1 with ribbing splices mutually, form the piece of certain width, in piece, can arrange longitudinal structure reinforcing bar 4, be furnished with warming plate 2 in the rib both sides of prestressed concrete base plate 1 with ribbing.
The superimposed superstructure of this sandwich prestressed concrete with ribbing is to form like this: (1) is shelved on prestressed concrete base plate lifting with ribbing on wall or the beam, is provided with between plate and plate and hangs mould; (2) warming plate is placed on the both sides of rib, as the bed die of upper strata cast-in-situ concrete; (3) concreting on base plate tamps the piece that forms between plate and plate, and concrete floating back in top layer forms the superimposed superstructure of sandwich prestressed concrete with ribbing.
Claims (5)
