Abstract
The utility model relates to composite slabs connected by using steel reinforcing bar 180-degree bending anchors and spiral bars in one span. The problems that the prefabricated concrete composite slabs have overlarge size and are inconvenient to transport and assemble are solved. The composite slabs are manufactured separately and are assembled and connected on site. The product comprises a prefabricated concrete composite slab body (1), wherein three surfaces of the prefabricated concrete composite slab body (1) are provided with exposed straight steel reinforcing bars (2); another surface of the prefabricated concrete composite slab body (1) in the horizontal direction is provided with an exposed U-shaped steel reinforcing bar (3); the U-shaped steel reinforcing bar of the prefabricated concrete composite slab body is in lap joint and anchored with the U-shaped steel reinforcing bar of the next prefabricated concrete composite slab body; the U-shaped steel reinforcing bars which are in lap joint and anchored sequentially form a full-length post-cast strip (4); the spiral bars (5) are wrapped by the U-shaped steel reinforcing bars on two sides of the full-length post-cast strip; a longitudinal full-length steel reinforcing bar (6) is inserted into the corner of the upper part of the full-length post-cast strip; the original stressed steel reinforcing bar (7) of a floor slab is arranged on the lower part of the full-length post-cast strip; and concrete (8) is poured on the full-length post-cast strip. The utility model is applied to assembling and connection of the prefabricated concrete composite slabs in the span.
