The set screw (18a) is screwed into the screw hole (17a) from the side surface of the movable block (31), and its tip portion is a concave stepped portion of the pivot pin (14) previously inserted into the pin hole (15) ( 16) and engage with the upper and lower steps of the concave step (16). Corresponding to the screw holes (17a) of the movable block (31), the end plate parts of the lower part of the top pivot (13) and the upper frame (5) are penetrated in the width direction of the door, and the holes for screw installation (35 (36) is formed. By inserting a driver (not shown) into the holes (35) (36) from the outside, the set screw (18a) is manually screwed into the screw hole (17a).

【0015】 図1のドア(3)の取付けは、従来工法に、次のネジ取付作業が追加されて 行われる。すなわち、従来同様に造営物(1)の開口部(2)にドア(3)を挿 入し、トップピボット上部(12)のピボットピン(14)を下降させて、トップピ ボット下部(13)のピン穴(15)に挿入する。而して後、上部フレ−ム(5)と トップピボット下部(13)の側端面の穴(35)(36)からドライバ−を挿入して 、可動ブロック(31)のネジ穴(17a)に止めネジ(18a)を螺装し、先端部を ピボットピン(14)の凹段部(16)に突出させておく。最後に、従来同様にアジ ャストスクリュ−(32)で可動ブロック(31)を移動させて、ドア(3)と開口 部(2)の隙間を調整する。Attachment of the door (3) in FIG. 1 is performed by adding the following screw attachment work to the conventional method.
