A concrete slab panel.

Conventional wire slab panels for construction are made of steel wire truss having shapes such as a regular warren truss type, deformed warren truss type, double warren truss type, etc. with iron wires, and the wire truss is spaced up at regular intervals to be aligned and placed on both sides thereof. In the center of the three-dimensional rebar structure welded with the steel wires vertically with polystyrene, polyurethane, and lightweight concrete, fabricate it on site and assemble it on-site and install the lower surface of the slab panel, that is, the ceiling of the lower layer with mortar. It was a skill to do.

The construction method using the wire slab panel manufactured in this way has several advantages in assembly when used with the wire wall panel manufactured in the same way, and it has advantages such as saving the labor, lightening the weight of the building, and reducing the air. It was true.

However, the conventional ones had to be mortared on the ceiling at the site, which led to various problems in construction, such as cracking and surface finish, and the labor and material management problems and waste associated with the construction of the site. Due to the limitations of the field construction, it was difficult to install the reinforcing bar on the ceiling, and the use of wire slab panels was extremely limited because of the very difficult mortar construction due to the structurally required thickness.

The object of the present invention is to firstly make up the conventional wire slab panel by PC concrete panel to compensate for the above mentioned problems associated with the field construction of the prior art, and secondly, the structural force to support the load of the high-rise building. It is used together with the prefabricated PC concrete wall panel to maintain the thickness of PC concrete panel, and the upper and lower wall panels and slab panels are welded to each other with structural reinforcing bars, and the parts are cast in place using unhardened concrete to integrate the entire building (monorithic). It is to provide a prefabricated PC concrete slab panel for building.
