The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
The present invention has two kinds of forms, and a kind of is rectangular teeth laminated floor slab with latch, and a kind of is the stepped tooth laminated floor slab of not being with latch.Mainly by following part, formed: base plate 1, segmented rib 2, latch groove 3, latch 4, lower floor's longitudinal reinforcement 5, lower floor's transverse reinforcement 6, rectangular teeth 7, rectangle teeth groove 8, stepped tooth 9, trapezoidal teeth groove 10.
In base plate 1, be enclosed with lower floor's longitudinal reinforcement 5, on it, there are two segmented ribs 2, plate longitudinal edge is set to dentation, for the rectangular teeth laminated floor slab with latch, in rectangular teeth 7 and rectangle teeth groove 8 stitching portions, latch groove 3 is set, base plate 1, segmented rib 2, latch groove 3, bottom longitudinal reinforcement 5, the parts integral formwork supports such as rectangular teeth 7, stepped tooth 9 and rectangle teeth groove 8, trapezoidal teeth groove 10, primary concreting moulding.This one-body molded base plate strength, the density of having guaranteed, has also guaranteed the globality that connects between each parts, and convenient and making.On each plate, have two segmented ribs 2 that are staggered in arrangement, each rib length is half of this plate length, and two rib stagger arrangement distribute, zero lap position.And segmented rib 2 is along the longitudinal reserved steel bar hole equably of rib, and reinforcing bar hole is for interting lower floor's transverse reinforcement 6, and the reinforced hole height of holes of each plate is consistent.For the rectangular teeth laminated floor slab with latch, its reinforced hole height of holes is not less than latch groove 3, and when reinforced hole height of holes is during lower than latch groove 3, the segmented rib 2 catching groove 3 upright projection places of fastening with a bolt do not establish reserving hole.When each plate has lifted, after rectangular teeth 7, stepped tooth 9 and rectangle teeth groove

embedding lower floor in trapezoidal teeth groove 10 places longitudinal reinforcement 5.Outside lower floor's longitudinal reinforcement 5 and lower floor's transverse reinforcement 6, stretch in base plate 1, reinforcing bar can be goed deep in beam after lifting, fixing better.Lower floor's transverse reinforcement 6, inserts in the reserved reinforcing bar hole of segmented rib 2 simultaneously, not only plays at vertical fixed head, avoids the generation of faulting of slab ends phenomenon.After building, it had both been imbedded at pouring layer, was fixed on again precast plate, had also increased the adhesion stress of the two, had improved globality and the rigidity of superimposed sheet, guaranteed better base plate 1 and in-situ layer collaborative work simultaneously.The longitudinal edge of base plate 1 adopts dentation.Rectangular teeth 7, stepped tooth 9 and rectangle teeth groove 8, trapezoidal teeth groove 10 are according to unified size design, make the two can be completely interlock mutually, during adjacent two plate contact, rectangular teeth 7, stepped tooth 9 can fully be filled rectangle teeth groove 8, trapezoidal teeth groove 10, can wrap up rectangular teeth 7, stepped tooth 9 completely with rectangle teeth groove 8, trapezoidal teeth groove 10, the contact of adjacent two plates is fitted together perfectly.Between the plate of rectangular teeth laminated floor slab, piece is rectangular toothed, can longitudinally form interlock in level, and relative displacement between the plate of constraint directions X, prevents the two plate generation changing of the relative positions.And piece between the plate of stepped tooth laminated floor slab, except having the advantage of above rectangular teeth, is gone back relative displacement between the plate that effectively planar retrains Y-direction, prevent that two plates from occurring separated.This kind of concavo-convex alternate dentation piece, is rectilinear floor than piece between plate, has more constraint, has strengthened the connection between plate, has limited relatively moving between plate, is not prone to crack, has improved the quality of floor.Rectangular teeth precast plate has latch groove 3, this latch groove 3 is arranged on rectangular teeth 7, stepped tooth 9 and rectangle teeth groove 8, trapezoidal teeth groove 10 places, and every plate only arranges half, when between adjacent two plates through assembled, after rectangular teeth 7, stepped tooth 9 dock completely with rectangle teeth groove 8, trapezoidal teeth groove 10, in two plate stitching portions, form complete latch groove 3, latch groove 3 upper surface profiles are the rectangle lower than segmented rib 1 a little more than base plate 1, and inner is the dumbbell shape slotted eye in recessed base plate.Latch 4 has two kinds of forms, both can be prefabricated also can be cast-in-place.Prefabricated latch 4 is for pressing latch groove 3 slotted eye same sizes, with concrete or the prefabricated dumbbell shape block forming of mortar.Cast-in-place latch 4, after superimposed sheet has docked, cast-in-place in latch groove 3 with concrete or cement mortar, can together construct with pouring layer.Latch 4 limited plate relatively moving in horizontal plane Y-direction, separated between the plate of having avoided.While as the bolt linking closely, has been limited vertically relatively moving between adjacent two plates again, to stoping playing a role of faulting of slab ends, has avoided formation and the development in crack.Its setting can be determined by actual conditions, can also can arrange at part tooth place in all tooth place settings, has provided two kinds of forms and see Fig. 1, Fig. 2 in this explanation.
