2. Description of the Related Art Hitherto, in a tiled roof, various types of face doors to be mounted on a nose bridge are known, and a plastic made by fitting a face plate into a fitting groove of a face door support is also commercially available.

[0003]

The conventional plastic face door has a length of about 1 meter for the face door support, which is nailed to a nose bridge, and then a face plate is fitted in a fitting groove. Or take a method of either fitting the face plate in the fitting groove of the face door support in advance and lifting it on the roof, and nailing the face door support to the nose bridge. I have. The former is a mode in which the roof is viewed from a high slope position to a low position, and a thin wall face plate must be fitted one by one into a narrow fitting groove, which is an extremely troublesome work. Since faceplates are piled on the roof and some of them must be held in hand, when the wind blows or rains, the faceplates fly and take time. In the latter, there is a problem that the face plate fitted with great effort slides down along the groove or is tightly fitted, and it takes time to move the face plate. In other words, since it is a plastic extrusion molded product, the fitting groove width is slightly widened or narrowed due to the difference in extrusion pressure, and the difference also occurs depending on the temperature.The thickness of the face plate is larger than the fitting groove width. If it is thin, the face plate will run down the groove when the face support is also inclined. Also, since about four face plates are fitted to one support, it is necessary to adjust the position of the face plates according to the size of the tile,
When the face plate was tightly fitted in the fitting groove, it sometimes did not move even if it was pulled with pliers or the like. SUMMARY OF THE INVENTION The present invention has been developed in view of those circumstances, with the objective of providing a face door free from the above-described trouble and a method of mounting the face door.

It is configured to be fitted vertically. The upper portion of the front side wall 5 of the face plate fitting groove 4 is formed higher than the upper surface of the upper plate 2, and the upper pressing body 5 and the lower supporting body 8 project vertically from the upper and rear surfaces of the front side wall 5. And a face plate locking portion 9 is formed. The upper surface of the lower support 6 has the same height as the upper surface of the upper plate 2 and is formed to be soft by reducing the thickness. The distance between the front end surface and the rear side wall 6 of the fitting groove 4 is equal to that of the face plate. Is set to a sufficient gap. The upper pressing body 7 has a press-contacting protruding body 7A protruding downward from the lower surface of the tip, and a gap between the lower surface of the protruding body and the upper surface of the lower support 8 is formed by a face plate 10A.
Is slightly narrower than the wall thickness of the upper press body 7, and the interval between the front end surface of the upper pressing body 7 and the rear side wall 6 of the fitting groove 4 is set to an interval where the face plate 10 enters. The upper push plate 2 is formed with nail holes 2A penetrating vertically at regular intervals in the longitudinal direction. In the above configuration, when the face plate 10 is placed on the upper surface of the upper plate 2 and the front end of the face plate 10 is inserted into the face plate locking portion 9 between the upper pressing body 7 and the lower support 8, the press-contacting projection 7 </ b> A The face plate 10 is pressed against the upper surface.
To prevent slipping out. In this state, a plurality of face doors 1 can be overlapped.

The face door 1 having the above structure is raised on the roof, the upper plate 2 is placed on the nose bridge 11, the front plate 3 is placed on the front of the nose bridge 11, and nails are inserted into any of the nail holes 2A. And fixed to the nose bridge 11. Then, when the base end of the face plate 10 is lifted up, the upper edge of the front end of the face plate 10 is pressed by the lower end of the upper pressing body 7 of the fitting groove 4 as shown in FIG. In this state, the front end of the face plate 10 pushes the lower support 8 down, so that the front end of the face plate 10 enters the face plate fitting groove 4. That is, even if the face door 1 is lifted on the roof with the face plate 10 sandwiched between the face plate locking portions 9 between the upper pressing body 7 and the lower support body 8, the face plate 10 does not slide down,
Also, on the roof, the face plate 10 can be quickly and completely fitted into the face plate fitting groove 4 only by raising the base end of the face plate 10. After that, the tiles can be tiled only by adjusting the interval between the face plates 10.
