  The present invention relates to a simple building such as a carport or a terrace.

  A roof of a simple building such as a carport or a terrace has a plurality of rafters arranged in parallel at intervals, and a resin roof panel is attached between adjacent rafters. Between the rafters, a central frame (sometimes called a purlin) is installed at an interval, and the roof panel is supported by the central frame from below.

As a conventional method of attaching the central bone, as described in Patent Document 1, a slit-shaped hole 27 is formed on the lower surface of the end of the central bone (main building 13) formed in a rectangular hollow cross section, An insertion part 26 that protrudes upward is formed on a support piece formed on the side surface of the rafter, and the insertion part 26 is inserted into the hole 27 on the lower surface of the middle bone to be locked. The engaging portion 51 is formed by cutting and raising the end portion side surface of the middle bone (horizontal member 5), and the engaging portion 51 is inserted into the notch 44 formed on the support piece on the rafter side surface. It locks to fix the middle bone. With such a structure, it is necessary to process both the middle bone and the rafter, and it takes time and effort to perform these processes, and the middle bone tends to be rattled due to a processing error.
In Patent Document 3, the middle bone (purlin member 2) is formed with a substantially I-shaped cross section, and a notch for inserting the end of the middle bone is formed in the attachment piece 5 provided on the side surface of the rafter, and the notch Are formed so that the projecting piece 3 is locked to the lower part of the middle bone when the projecting piece 3 having spring properties is formed on both the left and right sides and the middle bone is inserted into the notch portion of the rafter from above. . In the case of this structure, the rafter attachment piece 5 must be subjected to very complicated processing, and when a lateral force or twisting force is applied to the central bone, one of the protruding pieces 3 is pushed. The other projecting piece 3 is unlocked, and the middle bone may fall off.
In these simple buildings, since the roof panel is directly placed on the middle bone, sound may be generated due to vibration caused by wind.
