Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments, and all other embodiments obtained by persons skilled in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
As shown in fig. 1, the invention relates to an assembled integral floor slab connecting device, which is a reinforced concrete floor slab member prefabricated by a prefabricated PC platform or a reverse construction method mould. The invention comprises floor slab connection embedded parts 4 and beam connection embedded parts 3, as shown in fig. 2-3, wherein the floor slab connection embedded parts 4 comprise tension steel plates 5 and pull-tab steel plates 8. The tension steel plate 5 is provided with two second notches 12 in opposite directions, and the tension steel plate 8 is clamped in the second notches 12. The end of each assembled integral floor slab 1 is provided with two tension steel plates 5 and two pull-tab steel plates 8. Two tension steel plates 5 are installed at both ends of two parallel pull-tab steel plates 8. A gap 11 for coating concrete is arranged between the joints of the tension steel plate 5 and the two pull tab steel plates 8. The tension steel plate 5 at the far end of the pull-tab steel plate 8 is provided with a first notch 9 which is upward and used for fixedly connecting the reinforcing steel bar 7. As shown in fig. 4, the pull-tab steel plate 8 is provided with a plurality of holes 14 for passing through the steel bars, the holes are determined according to the diameter of the steel bars, and the distance between the holes 14 is determined according to the distribution distance of the stressed steel bars in the assembled integral floor slab 1, and the stressed steel bars pass through the holes for binding, so that the pull-tab steel plate 8 can be fixed on the assembled integral floor slab 1.
As shown in fig. 5, the beam upper connection embedded parts 3 include H-shaped embedded parts 14 and beam stirrups 6, the beam stirrups 6 are sequentially arranged on the assembly integral beam 2, the H-shaped embedded parts 14 are arranged between the beam stirrups 6 at intervals, and the top of the H-shaped embedded part 14 is provided with a third notch 13. The height of the beam stirrup 6 is higher than the third notch 13 on the H-shaped embedded part, so that the connecting steel bar 7 can be positioned between the beam stirrup 6 and the third notch 13. The connecting steel bars 7 are used for fixing the floor slab connecting embedded parts 4 and the beam connecting embedded parts 3.
The beam plate and the connecting fittings in the connecting points of the connecting device for assembling the integral floor slab are prefabricated in a factory. When the invention is used, as shown in fig. 1 and fig. 2, on-site assembly only needs to connect the first notch, the second notch and the third notch by adopting the steel bars, and then the right joint of the assembly integral beam and the assembly integral floor slab is subjected to the post-pouring of the concrete with the same grade, so that the operation of the working procedure is quick.
