Abstract

PURPOSE: To shorten construction period of time, and improve weathering by fitting the fold peripheries of overhanging frame upper and lower sashes in the recess grooves of stone material via an adhesive, and putting the packing of an overhanging frame inner peripheral surface in contact with the stone material rear surface in the case of fastening stone material on an overhanging frame provided on a structure via an attachment frame part. CONSTITUTION: A number of pieces of attachment frame parts 5 surrounded by a frames 1, 2 are provided on the wall surface of a structure, and sashes 8, 9 are secured to the outside surfaces of the attachment frame parts 5 so as to form an overhanging frame 12. A waterproof packing 13 is provided on the inner peripheral surface of the overhanging frame 12, and a downward folded periphery 15 is provided on the outside periphery of the upper sash 8 and upward folded periphery 16 is provided on the outside periphery of the lower sash 9. Then, stone material 17 is fixed to the overhanging frame 12 by respectively providing recess grooves 18, 19 on the upper and lower end surfaces of the wall decoration stone material 17, and fitting the folded peripheries 15, 16 in the recess grooves 18, 19 via an adhesive 20, and putting the rear surface in contact with the packing 13. By this structure, a curtain wall by the stone material 17 is formed easily, and the stone material 17 is disposed on the overhanging frame 12 by the adhesive 20 and packing 13 with good weathering.
