PURPOSE: To provide adhesiveness of a sufficient bond strength without prolonged press, by mingling a hot-melt adhesive with a room temp. setting adhesive, in bonding a panel frame to a face sheet in prefabricated houses.

CONSTITUTION: In prefabricated houses, upper and lower surfaces of a panel frame 1 made of wood, etc. and the area of contact of a face sheet 2 made of plywood, iron sheet, etc. with the panel frame 1 are applied with a hot-melt adhesive and a room temp. setting adhesive, and the face plates 2 are put on the panel frame 1, wherein the application is made in a molten state of the hot- melt adhesive. A number of resulting panels 3 are allowed to cure by heaping them up. The hot-melt adhesive becomes hardened readily to stick to the panels. During the cure, the room temp. setting adhesive becomes curred gradually by the clamping effect of the hot-melt adhesive hardened in advance to obtain a strong bond strength without resort to long-term press.
