図４を参照して説明を続けると、上窓枠部材４と共に連結片２を出荷する際には、連結片２の基部１８を上窓枠部材４の外面１０上に載置して係止突起１２ａと係止突起１２ｂに配置し、図４に実線で示す非作用位置に位置付ける。この非作用位置おいては、基部１８の特定縁２４が係止突起１２ａ及び１２ｂの他方、即ち係止突起１２ｂ、によって規定される溝１４ｂの底面に当接せしめられる。そして、円形開口３０を通してねじ部材４０を上窓枠部材４に螺着し、弧状開口３２の片端部を通してねじ部材４２を上窓枠部材４に螺着し、そして更に開放開口３４の開放端から離隔するがこれに隣接した位置で上窓枠部材４にねじ部材４４を螺着し、かくして上窓枠部材４に連結片２を固定する。非作用位置に位置付けられた連結片２の延出部２２はその一部が係止突条１２ａ上に位置するが、係止突起１２ａを超えて延出することはなく、連結片２はその全体が上窓枠部材４の幅内に位置する。従って、連結片２、特にその延出部２２、によって阻害されることなく、連結片２が固定された多数の上窓枠部材４をコンパクトに集積して建設現場に搬送することができる。また、連結片２を上窓枠部材４に連結するためのねじ部材４０、４２及び４４は上窓枠部材４に螺着された状態で建設現場に搬送されるので、ねじ部材４０、４２及び４４を紛失してしまう虞がない。
Continuing the description with reference to FIG. 4, when the connecting piece 2 is shipped together with the upper window frame member 4, the base 18 of the connecting piece 2 is placed on the outer surface 10 of the upper window frame member 4 and locked. It is arranged on the protrusion 12a and the locking protrusion 12b, and is positioned at the non-acting position shown by the solid line in FIG. In this non-acting position, the specific edge 24 of the base 18 is brought into contact with the other of the locking projections 12a and 12b, i.e., the bottom surface of the groove 14b defined by the locking projections 12b. Then, the screw member 40 is screwed to the upper window frame member 4 through the circular opening 30, the screw member 42 is screwed to the upper window frame member 4 through one end of the arcuate opening 32, and further from the open end of the open opening 34. The screw member 44 is screwed to the upper window frame member 4 at a position adjacent to the separated but adjacent to the upper window frame member 4, and thus the connecting piece 2 is fixed to the upper window frame member 4. A part of the extending portion 22 of the connecting piece 2 positioned at the non-acting position is located on the locking ridge 12a, but does not extend beyond the locking projection 12a, and the connecting piece 2 is the connecting piece 2. The whole is located within the width of the upper window frame member 4. Therefore, a large number of upper window frame members 4 to which the connecting piece 2 is fixed can be compactly integrated and transported to the construction site without being hindered by the connecting piece 2, particularly the extending portion 22 thereof. Further, since the screw members 40, 42 and 44 for connecting the connecting piece 2 to the upper window frame member 4 are conveyed to the construction site in a state of being screwed to the upper window frame member 4, the screw members 40, 42 and There is no risk of losing 44.
