Abstract

PROBLEM TO BE SOLVED: To obtain a joint structure in which a sealing material follows up a deformation together with an elastic material even if a surface material shrinks to deform the shape and the elastic material prevents the extension and contraction of a frame from directly transferring them to the surface material or the sealing material and the waterproof property at the joint is increased, byinterposing the elastic material with a specified thickness between the frame and the pair of surface materials adjacent thereto through the joint extended along the frame. SOLUTION: Surface materials 14, 15 are made of plaster boards and arranged adjacently to each other through a joint 18 between the opposite end edges 16, 17. A 2-5mm thick elastic material 12 is stuck to the surface 11 of the frame 10 along the frame. That is, the elastic material 12 is arranged along the joint 18 at the rear face of both surface materials 14, 15, between the frame 10 and the surface materials 14, 15. Even if the surface materials 14, 15 shrink to deform the shape, the sealing material 19 follows up the deformation together with the elastic material 12 to prevent the extension and contraction of the frame 10 from directly transferring them to the surface materials 14, 15 and the sealing material 19. Accordingly, the structure prevents cracks between the surface materials 14, 15 and the sealing material 19 and improves the waterproof property of the joint 18.
