【考案の詳細な説明】 本考案は上弦材、下弦材の間隔を、両者を連結するウェ
ブ材の取付は向きを変化させることにより可変とした架
構材に関する。[Detailed Description of the Invention] The present invention relates to a frame member in which the interval between the upper chord member and the lower chord member can be varied by changing the mounting direction of the web member that connects them.

従来の架構材にあっては、上弦材、下弦材の間隔は変更
できず、従って部材の架設場所に応じ夫々最適な厚さの
架構材を施工するには各種の寸度のものを別個に設計、
制作する必要があり、その種類が多岐にわたって管理上
極めて煩瑣であった。With conventional frame members, the spacing between the upper and lower chord members cannot be changed, so in order to construct frame members with the optimal thickness depending on the location where the members are to be constructed, it is necessary to separately construct members of various sizes. design,
They needed to be produced, and there were a wide variety of types, making management extremely cumbersome.

本考案はかかる問題点を解決しうる架構材の提供を目的
とし、以下本考案の一実施例を図面により説明する。The present invention aims to provide a frame member that can solve these problems, and one embodiment of the present invention will be described below with reference to the drawings.

寸度を変化させうる。In the arrangement of the through holes 6 a, 6 bt 6 c, the distance between the through holes a, 6 a located at the right angle corner part a and the through holes C, 6 bt 6 c located at the bottom corner part c is expressed as l. Then, the distance between the through hole 6b and the through hole c, 6c is /2f-:1.4/, and the distance between the through hole a and the through hole 6a in the right angle corner part a is 6b. The vertical distance to the diagonal line connecting c and 6c is 2. '10.7/, therefore, when one side (B or C) between the right angles is horizontal as shown in Figure 1 a, the through holes a, 6a, c, 6b, 6
The vertical distance between C and C is 11, or when the through holes a and 6a are placed above and the oblique side A is horizontal, as shown in Figure 1, the vertical distance is approximately 0.71, and depending on the orientation of the web material 4, The dimensions can vary by about 0.31.

Attachment holes C, 9b, and 9c are drilled at positions separated by f, so that even when the web material 4 is held horizontally with its oblique side A in the figure (Fig. 1b), the side B sandwiching the right angle , C
Even when the web material 4 is placed horizontally (FIG. 1a), each of the through holes a-Cv 6 a, 6 b, and 6 c of the web material 4 can be aligned with the milk layer.

要もなくまた管理上の煩を解消しうる。As mentioned above, the frame member of the present invention is configured so that the distance between the upper chord member and the lower chord member can be changed by changing the direction of the web member that connects the two members. Even at the construction site, it is possible to optimally and easily set the spacing between the upper and lower chord members, and to increase the bending strength, eliminating the need to individually design and manufacture various frame members with different spacings. It can eliminate the above troubles.
