FITTING STRUCTURE OF FRAME BODY TO OPENING OF BUILDING

MIZOTA TOYOHIKO

To provide a fitting structure of a frame body to an opening of a building, causing no lowering of fitting strength of the frame body to an opening of the building, caused by movable fitting of a fitting part abutting member in a cavity part with a fine clearance, and allowing for improved fitting strength.SOLUTION: A frame body 1 is constituted by: a frame body main body 2 which has a cavity part 21 opened to an outer peripheral side facing a fitting part J of a building F side, and in which an inner peripheral side of the cavity part 21 is closed by integrally and movably forming a screw insertion part 22 having a rear face 22a formed of an inclined plane facing to an anti-opening side and a screw insertion hole 22b, and guide parts 28 are formed on both sides in the width direction in the cavity part; and a fitting part abutting member 3 which is fitted to the cavity part 21, has a front face 31 formed of an inclined plane abutting on the rear face 22a of the screw insertion part 22 and facing to the opening side, has guided parts 38 inserted into the guide parts 28 formed to the frame body main body 2, with a rear face 32 made to abut on the fitting part J of the building F side.SELECTED DRAWING: Figure 16

【課題】取付部当接部材が空洞部内に微小なクリアランスを設けて可動に装着されていることに起因する建築物の開口部に対する枠体の取付強度の低下をなくし、取付強度を向上することができるようにした建築物の開口部の枠体の取付構造を提供すること。【解決手段】枠体１を、建築物Ｆ側の取付部Ｊに対向する外周側に開口する空洞部２１を備え、空洞部２１の内周側を、反開口側向きの傾斜面からなる後面２２ａ及びビス挿通孔２２ｂを備えたビス挿通部２２を一体かつ可動に形成することで閉鎖するようにするとともに、空洞部内の幅方向の両側にガイド部２８を形成した枠体本体２と、空洞部２１に装着され、ビス挿通部２２の後面２２ａに当接する開口側向きの傾斜面からなる前面３１を備え、枠体本体２に形成したガイド部２８に嵌挿する被ガイド部３８を幅方向の両側に形成した、建築物Ｆ側の取付部Ｊに後面３２が当接される取付部当接部材３とで構成する。【選択図】図１６
