By the way, in a simple roof such as a shelter provided from a flat surface to an inclined surface, the angle of the roofing material changes at the curved portion of the roof (it inclines with respect to the horizontal). The angle of the purlin also changes. Therefore, the slanted purlins are attached in contact with the side surface of the rafter in the vertical posture. In such a case, in the conventional purlin material mounting structure, the end portion (edge) of the purlin is cut diagonally according to the inclination angle so that it will abut the side surface of the rafter without a gap and at a right angle from the side surface of the rafter. The protruding connecting block must also be cut diagonally according to the angle of the purlin. In particular, the connecting block
Since it is a short member unlike the purlin, there is a problem that it is difficult to perform accurate cutting and the work becomes complicated.

The present invention is a mounting structure for a purlin material which allows the purlin material to be easily attached to the hanging lumber at an arbitrary angle within the vertical plane without impairing the design of the mounting portion of the purlin wood to the hanging lumber. Its purpose is to provide.
