Description

  The present invention relates to a roof material installation structure formed using a flat roof material.

  2. Description of the Related Art Conventionally, a method for arranging roof materials in a staggered manner is generally used as a method for forming a roof material installation structure. For example, in the roof construction method described in Patent Document 1, an insertion portion of a fixing bracket is inserted into a ridge-deck engaging portion of an adjacent roof plate, and the fixing bracket is attached to a roof base material by a fixing bracket through a through hole. Then, the end of the eaves of another roof plate is engaged with the hook holding portion of the fixing bracket.

  In recent years, in order to improve the environment of the back of a hut, construction has been carried out in which a field board is doubled and a space between the two is used. In this case, since the field board is doubled, the weight of the roof increases. Therefore, a ventilation space is also formed only with a pedestal such as a vertical cross.

  Next, the installation structure of the roof material 2 formed using said roof material 2 is demonstrated.

  FIG. 1 shows an example of a laying structure of the roofing material 2, which is constructed and formed as follows. First, as shown in FIG. 1B, a plurality of rafters 13 are installed at regular intervals in the eaves ridge direction, and then a field board 15 such as plywood is stretched on these rafters 13. Next, after placing underlaying material 16 such as asphalt roofing on the field board 15, a plurality of vertical rails 12 are installed at regular intervals in the eaves ridge direction to form the roof foundation 1. In FIG.1 (b), although the space | interval of the vertical bars 12 adjacent to the left-right direction is a half of the space | interval of rafters 13, it is not limited to this.

  Next, the side edges 3 of the first-stage roof material 2 are abutted on the vertical rail 12 which is the roof foundation 1 from the left or right side of the eaves side, and the plurality of roof materials 2 are adjacent to each other in the left-right direction. Arrange. At this time, if the second fixing tool insertion hole 7 is formed in a cutout shape at the same location of the side end portions 3 of the left and right roof materials 2, the second fixing tool insertion holes 7 of the left and right roof materials 2 are matched. By doing so, the positions of the eaves-side end portions 5 and the ridge-side end portions 4 of the left and right roof materials 2 are naturally aligned, and alignment can be easily performed. In addition, since the ridge side edge part 4 of the roof material 2 on the eaves side is covered and concealed by the eaves side part of the roof material 2 on the ridge side, at least the roof material 2 other than the roof material 2 arranged on the ridge side is at least The eaves side edge parts 5 should just align.
