なるうえ、耐久性にも欠けていた。 When creating a fireproof structure for the gable soffit of a roof, the conventional construction method was to cover the main building with mortar, but this process required steps such as attaching lath to the main building, which was time-consuming. However, it was expensive and lacked durability.

本考案は上記欠点を除き、施工を容易にし、安

とを目的とする。 The object of the present invention is to eliminate the above-mentioned drawbacks and provide a non-combustible purlin structure that is easy to construct, inexpensive, and highly durable.

以下本考案の一実施例を図面にもとづいて説明

る。 Therefore, the purlin board material 2 is formed into a rectangular board shape using asbestos cement material, and includes a lower purlin board 21 attached to the lower surface of the purlin and a side purlin board 22 attached to the upper side and lower side of the purlin along the roof slope. are combined. That is, as shown in the third figure, the lower purlin board 21 has a tip angle of about
A cutting surface 21a of 43 degrees is formed, and the tip thereof is a chamfered portion 21b. Further, as shown in the fourth figure, a dead surface 2 having the same shape as described above is also provided at one end (lower end) of the side purlin board 22 in the purlin height direction.
2a is formed, and the tip thereof is a chamfered portion 22b. These chamfered portions 21b and 22b are configured so that when the respective purlin plates 21 and 22 are assembled as described later, adjacent ones thereof are flush with each other. The purlin boards 21 and 22 are cut in advance to have approximately the same length as the length of the purlin 1 exposed at the gable side eaves.

A non-combustible caulking material is applied to each of 1a and 22a to seal them, and nailed to the main building 1 to cover three sides of the main building. If the width of the side purlin board 22 is too wide, the other end in the width direction is cut as appropriate. On the other hand, the lower surface purlin board 21 is not cut even if its width is wider than the purlin 1, and a gap is formed on the upper side along the roof slope of the purlin 1. Then, a spacer 3 made of plywood is attached to the gap.
