Feature of the present utility model is that also described prefabricated top side wall has anchor rib.Behind the concreting, anchor rib and cast-in-situ concrete bonding, build-in, the collaborative work between prefabricated sidewall and the cast-in-situ concrete is stronger, and stress performance, the globality of cassette ceiling are better.
Feature of the present utility model also is on the described prefabricated sidewall hold item is arranged.Hold item on the prefabricated sidewall can be used for shelving prefabricated panel, and prefabricated panel places on the hold item, plays the effect of template.After treating that concrete reaches certain intensity, remove hold item, prefabricated panel is placed on the projection of prefabricated sidewall bottom.
Feature of the present utility model also is on the described prefabricated panel separation layer is arranged.For preventing cast-in-situ concrete and prefabricated panel bonding, before the concreting, on prefabricated panel, lay separation layer, like this, prefabricated panel is easy to separate with cast-in-place top board.
Feature of the present utility model is that also described prefabricated sidewall has integral side walls, assembly unit sidewall.Prefabricated sidewall can be whole, also can be assembled by the precast plate more than two or two, makes that like this making of prefabricated sidewall is comparatively convenient, implements easily.
Feature of the present utility model is that also described prefabricated panel is made up of the precast plate more than one or.Prefabricated panel can be assembled for the precast plate of different size, makes the easy to make of precast plate, and can satisfy different design and construction needs.
Feature of the present utility model also is on the described prefabricated panel hole is arranged.Hole on the prefabricated panel can be used to settle bolt, after cast-in-situ concrete reaches certain intensity, utilizes bolt that prefabricated panel is separated with cast-in-place top board, and prefabricated panel is placed on the projection of sidewall bottom.
