In order to achieve the above object, the utility model provides a piece connection structure for connect two adjacent superimposed sheets, include the reinforcing bar net of laying in two superimposed sheets tops to and a plurality of drawknot pieces of connecting in the piece between two superimposed sheets, drawknot piece one end is for pegging graft the grafting portion in the piece, the other end for with the drawknot portion of reinforcing bar net joint.

Furthermore, the insertion part of the pulling piece is a vertical rod.

Furthermore, the pulling part of the pulling piece is a bent hook rod.

Furthermore, the drawknot part of the drawknot component is an annular rod.

The utility model also provides a prefabricated superimposed sheet, including first superimposed sheet and second superimposed sheet, the top of first superimposed sheet and second superimposed sheet has poured the concrete, has also poured the concrete in the piece between first superimposed sheet and second superimposed sheet, the reinforcing bar net and the drawknot piece of piece connection structure all bury and apply in the concrete.

Furthermore, the side faces of the first laminated slab and the second laminated slab, which are adjacent to each other, are provided with grooves.

Further, the groove is a trapezoidal groove.

The utility model has the advantages that:

the splicing seam connecting structure is simple in structure, and can quickly and stably connect the laminated slab and the reinforcing mesh;

secondly, the pulling piece has simple structure and low manufacturing cost, and is very convenient and fast when being combined with two laminated plates;

thirdly, use this connection structure's prefabricated superimposed sheet sound construction, the reinforcing bar net passes through the drawknot piece interlock in the concrete of prefabricated superimposed sheet, is difficult for appearing droing, through the recess that sets up in the side of two superimposed sheets, can further make the taut interlock of concrete with first superimposed sheet, second superimposed sheet and reinforcing bar net.

Drawings

Fig. 1 is a schematic structural view of an embodiment of the prefabricated composite slab of the present invention (the tie portion is a hook bar);

fig. 2 is a schematic view showing a structure of another embodiment of the prefabricated composite panel according to the present invention ((the drawknot portion is a ring-shaped rod).

In the figure: 1. a first superimposed sheet; 2. a second laminated plate; 3. a reinforcing mesh; 4. a pulling member; 5. a plug-in part; 6. a drawknot section; 7. a groove; 8. a vertical rod; 9. bending the hook rod; 10. an annular rod; 11. concrete; 12. and (6) splicing.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

referring to fig. 1 to 2, the patchwork connecting structure for connecting two adjacent laminated boards comprises a mesh reinforcement 3 laid over the two laminated boards, and a plurality of tie members 4 connected in a patchwork 12 between the two laminated boards, wherein one end of each tie member 4 is a plug-in part 5 plugged into the patchwork 12, and the other end is a tie part 6 for clamping with the mesh reinforcement 3.

The utility model discloses when two superimposed sheets splice, need be in the same place two superimposed sheets with the elder generation, after the superimposed sheet splices, as required, peg graft between the superimposed sheet through grafting portion 5 with a plurality of drawknot spare 4, drawknot portion 6 joint is to reinforcing bar net 3, last among the piece 12 between two superimposed sheets top and the superimposed sheet filling concrete 11, the concrete that fills 11 buries reinforcing bar net 3 and drawknot spare 4 and applies, after waiting for concrete 11 to condense, this drawknot spare 4 can be drawed reinforcing bar net 3 and first superimposed sheet 1 and second superimposed sheet 2 and bond, the bite-force is strong, reinforcing bar net 3 can not appear droing.

Further, the inserting part 5 of the pulling piece 4 is a vertical rod 8. Since the gap of the butt joint 12 between the two superimposed plates is small, the insertion part 5 of the fastener 4 is provided as the vertical rod 8.

Furthermore, the drawknot part 6 of the drawknot member 4 is a hook rod 9. Since the knotting portion 6 of the knotting element 4 is a hook bar 9, the steel bar net 3 can be firmly knotted by the hook bar 9.

Further, the drawknot portion 6 of the drawknot member 4 is an annular rod 10. Besides the drawknot portion 6 of the drawknot member 4 being the hook bar 9, the drawknot portion 6 may be provided as an annular bar 10, and the drawknot laminated slab and the mesh reinforcement 3 which can also stabilize the drawknot member 4 can be provided by the annular bar 10, and of course, the drawknot portion 6 may be provided as a horizontal bar or a connecting bar of other shape in addition to the annular bar 10, and the function of drawknot the mesh reinforcement 3 and the laminated slab can be achieved.

The utility model also discloses a prefabricated superimposed sheet, including first superimposed sheet 1 and second superimposed sheet 2, concrete 11 has been filled in the top of first superimposed sheet 1 and second superimposed sheet 2, and the piece between first superimposed sheet 1 and second superimposed sheet 2 has also been filled with concrete 11, piece connection structure's reinforcing bar net 3 and drawknot piece 4 bury and apply in concrete 11. After this prefabricated superimposed sheet's first superimposed sheet 1 and second superimposed sheet 2 are connected through the piece structure, sound construction, life is longer, and the building quality of using this prefabricated superimposed sheet is better.
