JUNCTION

摘要

The present invention is related to a joint structure for sandwich panels comprised of a mineral wool core (1) which is advantageously clad on both sides by skin sheets (2) bonded to the mineral wool core. The mineral wool core (1) is left bare on the edge remaining between a groove-and-tongue structure (3, 3') included in the skin sheet structure to accomplish the mating of the surfaces of the mineral wool core of the panels to be jointed. To assure the tightness of the joint, the mineral wool core (1) is at the area of the tongue-and-groove joint subjected to a higher compressive contraction in the mating direction of the panels than elsewhere in the core after the skin sheet structures of the panels are pushed home in their tongue-and-groove joints.
