Sandwich concrete panel and method of making the same

摘要

The invention relates to a sandwich concrete panel, which includes a body-forming internal leaf (1), an insulation layer (2) of mineral wool installed thereon, and an outer leaf (3) installed on top of the insulation layer. The mineral wool insulation layer (2) is lamellar in structure, in which lamellae (2b) the fibers of mineral wool lie in an orientation substantially perpendicular to the surfaces of the internal and outer leaves. The outer leaf (3) is constructed in fiberplastic-reinforced concrete and the internal leaf (1) as well as the outer leaf (3) are secured to each other by push-through trusses (4b) extending through the insulation layer (2). The invention relates also to a method of making a sandwich concrete panel.
