Fabricated building load-bearing insulating wallboard

The utility model belongs to the technical field of building protection precasting member structures, and relates to a fabricated building load-bearing insulating wallboard, which includes a load-bearing upper layer hard facing slab and a load-bearing lower layer hard facing slab, wherein a polyurethane layer made of polyurethane material is arranged between the load-bearing upper layer hard facing slab and the load-bearing lower layer hard facing slab; and the upper layer hard facing slab and the lower layer hard facing slab can be integrally one-step formed in virtue of the self-adhesive performance of the polyurethane material; the polyurethane layer on the side along the long edges of the hard facing slabs is designed to be trapezoidal concave; and the polyurethane layer on the other side is designed to be trapezoidal convex. The fabricated building load-bearing insulating wallboard is quick and convenient to mount and dismount, reliable in thermal insulation performance and excellent in bearing capacity,
