  The first convex portion 223 of the cover 2 is placed on the support member 3. The support member 3 supports the cover 2 if the first convex portion 223 is placed. Therefore, the shape of the support member 3 of the present embodiment is not limited to a substantially C shape in cross section as described above, and may be any shape as long as the first convex portion 223 can be easily placed.

  The support member 3 is disposed on the windbreak plate 12 so that the cover 2 is in a predetermined position when the first convex portion 223 of the cover 2 is placed. Here, the predetermined position of the cover 2 indicates the position of the cover 2 as shown in FIG. That is, at a predetermined position, the lower covering portion 21 is positioned below the windbreak plate 12, the first convex portion 223 and the second convex portion 224 are in contact with the windbreak plate 12, and the upper covering portion 23 is above the climbing tree 114.

  The support member 3 is fixed to the windbreak plate 12 as shown in FIG. 2B. Moreover, it is preferable that the supporting member 3 is provided in the windbreak board 12 over the full length of a roof inclination direction. The support member 3 may be divided into a plurality of pieces and fixed to the windbreak plate 12 in a straight line while being spaced along the roof inclination direction.

  The collar structure 1 of the present embodiment has the above-described configuration.

  The construction method of fixing the cover 2 to the windbreak plate 12 in the cover structure 1 will be described.

  In the conventional rake structure, in order to fix the cover to the windbreak plate so that the cover is in a predetermined position, the tip portion of the base plate protruding outward from the windbreak plate is used for alignment.

  Therefore, the builder holds the first convex portion of the cover while pressing the upper wall portion of the cover against the lower surface of the top portion of the base plate, and holds the fixture on the back wall portions of the first convex portion and the second convex portion. The cover had to be fixed by penetrating it and screwing it into the windbreak plate.

  However, in the case 1 of the present embodiment, the cover 2 can be positioned at a predetermined position simply by placing the first protrusion 223 of the cover 2 on the support member 3 fixed to the windbreak plate 12. it can.

  Therefore, the installer places the lower wall portion 221b of the cover 2 on the upper surface portion 33 of the support member 3, and penetrates the fixing tool 40 into the back wall portion 221a of the first convex portion 223 or the second convex portion 224 to break the wind. The cover 2 can be fixed in place by simply screwing it into the plate 12.

  Accordingly, in the rib structure 1 of the present embodiment, the support member 3 that can temporarily support the cover 2 at a predetermined position is provided on the windbreak plate 12, so that the cover 2 can be easily fixed to the windbreak plate 12. be able to. Therefore, the construction burden on the installer is reduced.

  Further, in the conventional rake structure, a field board made of wood is used for alignment. Here, since the field board is a plate material composed of plywood, wood wool, and wood pieces, unevenness is easily formed on the surface of the field board. If unevenness occurs on the surface of the base plate, the accuracy of the cover alignment will be low. Therefore, it has been difficult to fix the cover by inclining the cover in parallel with the roof inclination direction in the conventional structure.

  However, in the cover structure 1 of the present embodiment, the cover 2 is aligned using the support member 3 without using the base plate 112. Here, when the support member 3 is formed of a material having high rigidity such as aluminum, stainless steel, or synthetic resin, the support member 3 is difficult to bend and the support member 3 is less likely to be uneven.

  Thereby, it becomes easy to incline and fix the cover 2 in parallel with the roof inclination direction. In this case, it is preferable that the supporting member 3 is fixed to the windbreak plate 12 over the entire length in the roof inclination direction.

<Modification>
A modified example of the rib structure 1 of this embodiment will be described with reference to FIG.

  In the brittle structure 1 of this modification, the first convex portion 223 has a protruding portion 225 on its lower wall portion 221b. Further, the support member 3 has a hook portion 331 on its upper surface portion 33.

  The protruding portion 225 is provided so as to protrude downward from the inward D1 side end portion of the lower wall portion 221b of the first convex portion 223. The protruding portion 225 has a substantially rectangular shape in sectional view, but the shape is not limited. Also, in the structure 1, there is a gap (hereinafter referred to as a first gap) between the end of the protruding portion 225 on the outward D2 side and the portion of the flat portion 226 from the first convex portion 223 to the second convex portion 224. 1 gap 25) is formed.

  The hook portion 331 is provided so as to protrude upward from the end portion on the outwardly facing D2 side of the upper surface portion 33 of the support member 3. The upper part of the hook portion 331 has a generally bowl shape in cross section. Further, the upper end portion of the hooking portion 331 is inclined so as to be positioned downward as it goes inward D1. Further, in the structure 1, a gap (hereinafter referred to as a second gap 34) is formed between the hook portion 331 and the windbreak plate 12.

  The hook portion 331 of the support member 3 is inserted into the first gap 25. The protruding portion 225 of the cover 2 is inserted into the second gap 34. In other words, the protruding portion 225 is positioned on the inward direction D1 side with respect to the hooking portion 331, and the lower end of the protruding portion 225 is positioned below the upper end of the hooking portion 331.

  Thereby, in the rib structure 1 of the present modification, when the cover 2 moves outward from the predetermined position D2, the protruding portion 225 is hooked on the hook portion 331 of the support member 3. Therefore, even if the builder releases his hand, the cover 2 is arranged at a predetermined position, reducing the burden on the builder.

  The construction method for fixing the cover 2 to the windbreak plate 12 in the cover structure 1 of the present modification will be described below.

The installer inserts the protruding portion 225 of the cover 2 into the second gap 34 and inserts the hook portion 331 of the support member 3 into the first gap 25. The installer passes the fixing tool 40 through the back wall portion 221a of the second convex portion 224 and twists it into the windbreak plate 12 to fix the cover 2 to the windbreak plate 12.

  In the conventional crack structure, the cover is fixed to the windbreak plate by screwing a fixing tool into the first and second protrusions. Therefore, if there is unevenness on the outward facing surface of the windbreak plate, the flat portion between the first convex portion and the second convex portion in the outer covering portion is likely to be bent.

  However, in the rib structure 1 of this modification, since the protrusion 225 of the cover 2 is hooked on the hook 331 of the support member 3, only the second protrusion 224 needs to be fixed by the fixture 40. Therefore, even if there is unevenness on the outward facing D2 side surface of the windbreak plate 12, the flat portion 226 between the first convex portion 223 and the second convex portion 224 in the outer covering portion 22 is unlikely to be bent.

  The collar structure 1 of the present embodiment has the following configuration.

  The structure 1 includes a roof base 11, a windbreak plate 12 fixed to a lower portion of the end of the roof base 11, and a cover 2 that covers the end of the roof 11 and the windbreak 12. Is provided. The cover 2 includes an outer covering portion 22 that covers the end portion of the roof base 11 and the windbreak plate 12 from the side, and an upper covering that is provided on the outer covering portion 22 and covers the end portion of the roof base 11 from the upper side. Part 23. The outer covering portion 22 includes a first convex portion 223 projecting to the side of the windbreak plate 12 at a part corresponding to the lower end portion from the upper end portion of the windbreak plate 12, and It has the 2nd convex part 224 which protrudes in a part of part corresponding to a lower end part to the windbreak board 12 side. A support member 3 that protrudes toward the outer covering portion 22 and supports the first convex portion 223 is fixed to the windbreak plate 12. The support member 3 is arranged such that the cover 2 is fixed at a predetermined position.

  As a result, if the support member 3 is loose, the cover 2 can be temporarily supported at a predetermined position, and the construction burden on the installer is reduced.

  In addition, the structure 1 of the modification of the present embodiment has the following configuration.

  The 1st convex part 223 has the protrusion part 225 which protrudes below from the lower end part. The support member 3 has a hooking portion 331 that protrudes upward from the upper end portion of the support member 3 and is hooked with the protruding portion 225 of the cover 2 if it is located at a predetermined position.

  The 1st convex part has the projection part 225 which protrudes below from the lower end part. The support member 3 has a hook portion 331 that protrudes upward from its upper end. The protruding portion 225 is located between the hook portion 331 and the windbreak plate 12.

  Thereby, only the 2nd convex part 224 should just be fixed by the fixing tool 40, and even if there is unevenness in the surface of the windbreak board 12, between the 1st convex part 223 and the 2nd convex part 224 in the outer coating | coated part 22 It is difficult for the flat portion 226 to be bent.
