[Prior art]
As this kind of conventional parting edge, for example, the technique shown in FIG. 7 and FIG. 8 developed by the present patent applicant and applied for a patent (Japanese Patent Application No. 4-247154) is known. In this technique, a steel sheet is bent into a U-shaped cross section by a roll homing method to form a parting edge 51, and a ventilation hole 54 is formed in each of an upper plate 52 and a lower board 53 of the parting edge 51. Bending ribs 52a and 53a were formed by bending the leading edge of the lower plate 53 into the U-shaped groove 55, respectively.
[0003]
The eaves ceiling plate 56 is sandwiched and supported by the bent ribs 52a and 53a formed as described above. In the case of the parting edge 51, the ventilation passage 57 is formed by the ventilation hole 54 and the U-shaped groove 55 described above. Further, a nonflammable volume expansion material 58 was attached to a part of the ventilation passage 57. In the figure, 59 is a roof, 60 is a nose cover plate, and 61 is an outer wall.

[Problems to be solved by the invention]
However, in the case of the above-described ventilation structure, it is necessary to use a relatively thick steel plate in order to form the parting edge 51 by bending one steel plate by the roll homing method. Furthermore, in order to continuously drill a large number of ventilation holes 54 in the upper plate 52 and the lower plate 53, the strength of the parting edge 51 is further weakened, so that a thicker steel plate must be used. there were. In addition, since the ventilation hole 54 is formed, there is a problem that the cutting edge 51 can have a large number of cut surfaces, and the cut surfaces tend to rust.
[0005]
In addition to the known technique, for example, a technique as shown in Japanese Utility Model Laid-Open No. 60-92034 has been developed. This technology consists of two parts: a parting edge body and a parting edge holder that can be fitted around the parting edge body, and the outer wall and the eaves ceiling are fitted and attached to the parting edge holder. This is the structure.
[0006]
By the way, even in the latter parting edge structure, since a number of ventilation holes are continuously drilled in the parting edge body, there is a problem in the strength of the parting edge body, and the cut surface by the ventilation holes increases. There was a problem that this cut surface was easily rusted.
[0007]
The present invention relates to a completely new ventilation structure developed in view of the above-mentioned conventional problems and its component fittings, and in particular, by making the component parts three points, The piece fittings that are molded by thin homing using the roll homing method and support the eaves ceiling board can be manufactured by pressing with a thick steel plate with sufficient strength, and a ventilation hole is made in the parting edge. It provides a completely new technology that allows the ventilation structure to be constructed without any problems.
