SCREEN DEVICE ATTACHING FRAME FOR BUILDING OPENING AND CONSTRUCTION METHOD OF THE SAME

PROBLEM TO BE SOLVED: To provide an attaching frame capable of easily coping with a projected step or a recessed step on a frame inner surface of a building opening where a screen device is to be installed when it is present, and capable of being installed with excellent workability suited to various kinds of installation sites, and its construction method.SOLUTION: An attaching frame 10 fixed to the inner surface of a frame 2 of a building opening 1 to form an installation frame of a screen device 3 is formed into a U shape on the cross section including erected walls 10b bent in the same direction from both side ends of an attaching surface 10a of the screen device. On the distal end of the erected wall, an attaching groove 10d for attaching a burial member 12 such as mohair is provided. The erected wall 10b is cut from the distal end side for a length equivalent to the height of the projected step 2a of the frame, and in order to break the erected wall by bending the erected wall at the distal end position of the cut, many folding grooves 10c extending in the longitudinal direction of the attaching frame are recessed on the erected wall 10b at a small interval.
