INSTALLATION STRUCTURE OF WALL SURFACE DECORATIVE SHEET

PROBLEM TO BE SOLVED: To provide an installation structure excellent in workability and safety by automatically forming a joint clearance of specified width between wall surface decorative sheets provided adjacent to each other in the vertical direction. SOLUTION: An installation horizontal frame 7 to be horizontally set and fastened on a bed angle 2 fastened on a wall surface (a) of a frame body and a wall surface decorative sheet 3 with a panel installation upper frame 4 fastened on an upper end of the back surface side and a panel installation lower frame fastened on an lower end so that they extend in the cross direction are constituted. An engagement structure (engagement edge part 44) and a fastening structure (machine screw 9) against the installation horizontal frame 7 are constituted on the panel installation upper frame 4, and a hooking structure (suspended engagement groove 53) against the panel installation upper frame 4 is constituted on the panel installation lower frame. The panel installation upper frame 4 of the wall surface decorative sheet 3 is engaged with the installation horizontal frame 7 by an engagement structure in a state where the panel installation lower frame of the wall surface decorative sheet 3 to be fastened on the upper side is engaged with the panel installation upper frame 4 of the wall surface decorative sheet 3 provided adjacent to the lower side, and it is tightened and fastened by a tightening structure.
