[Prior art]
In recent years, flat roof tiles made of lightweight materials are often used for roofing, and in particular for extension and renovation, lightweight resin flat roof tiles are frequently used because of their ease of handling.
[0003]
For example, as illustrated in FIG. 11, such flat roof tiles are piled up in order from the eaves side. First, the lower flat roof tile (1) is inserted into the pier ( 2) Screw it on the roof base material. At this time, there may be employed a structure in which the roof tile fixing bracket (3) for fixing the front end portion (that is, the end portion on the eaves side) of the upper flat roof tile (1) is attached at the same time as screwing.
[0004]
Specifically, as illustrated in FIG. 12, for example, the tile fixing bracket (3) has a tile insertion portion (31) bent in the ridge direction at the flat plate tip, and a screw opening ( 32), and when fixing the lower flat roof tile (1) with screws, the roof base material such as piers (2) and field boards through the screw openings (32) of the roof tile fixing bracket (3) By screwing into the flat roof tile (1), the rear end of the lower flat roof tile (1) is fixed onto the roof base material, and the roof tile fixing bracket (3) is also fixed onto the rear end of the flat roof tile (1). Then, the upper flat roof tile (1) is placed so that its front end is inserted into the tile insertion part (31) of the roof tile fixing bracket (3) on the lower flat roof tile (1). Screw the end together with the tile fixing bracket (3).
[0005]
Due to the presence of the tile fixing bracket (3), the rear end portion of the flat roof tile (1) is firmly fixed with screws, and the tip portion is firmly fixed by the tile insertion portion (31) of the tile fixing bracket (3). Will be retained. This structure is particularly useful for stacking lightweight flat roof tiles (1) made of resin or the like, and by holding and fixing the leading edge of the tile with the roof tile fixing bracket (3), the leading edge of the roof floats in a strong wind and causes a flutter. Can be effectively prevented.

[Problems to be solved by the invention]
However, even in the laminated structure of the flat roof tiles (1) using the excellent roof tile fixing bracket (3) as described above, there are practically the following points to be improved.
[0007]
That is, even if the fixing of each stage is ensured by the tile fixing bracket (3), rainwater may enter from between the upper flat roof tile (1) and the lower flat roof tile (1). For this reason, in order to enhance the waterproof effect, it is necessary to increase the stacking allowance between the upper flat roof tile (1) and the lower flat roof tile (1). This increases the number of tiles required for the roof area, which is not economical.
[0008]
Therefore, in view of the circumstances as described above, the invention of this application is intended to improve the waterproof property while reducing the stacking allowance for the flat roof tile (1) stacked using the tile fixing bracket (3). The objective is to provide a new flat roofing structure for flat tiles.

DETAILED DESCRIPTION OF THE INVENTION
The invention of this application has the features as described above, and the embodiment will be described in more detail below with reference to the drawings.
[0012]
As illustrated in FIG. 11 and FIG. 12, the rear end portion of the lower flat roof tile (1) is screwed and fixed to the roof base material such as the pier (2) and the base plate together with the roof tile fixing bracket (3). In the structure in which the flat roof tiles (1) are piled up so that the tip of the flat roof tile (1) is inserted and held in the tile insertion part (31) of the fixing bracket (3), for example in FIGS. As illustrated, the flat roof tile (1) has a waterproof rib portion (11) having a certain height from the roof surface, which extends continuously in the left-right lateral direction along the rear end, and is fixed to the roof tile. The metal hook (3) is hooked to the waterproof rib (11) of the flat roof tile (1), the rib hooking portion (33) is the roof tile insertion portion (31) (tip position) and the screw opening (32) (rear end). It is assumed that it is in a predetermined position between (position).
[0013]
When fixing with screws, the rib hooking portion (33) is hooked to the waterproof rib portion (11) of the flat roof tile (1) and attached to the rear end of the flat roof tile (1). 2) Fix to the roof base material such as 2 with screws (4).
[0014]
As a result, the waterproof rib portion (11) can be obtained even if the overlap of the upper flat roof tile (1) and the lower flat roof tile (1) is less than the conventional one, while maintaining the tile fixing effect of the roof tile fixing bracket (3). Therefore, it is possible to effectively prevent rainwater from entering the roof base material side.
[0015]
The rib hooking portion (33) of the roof tile fixing bracket (3) may have any shape that can be hooked so as to get over the waterproof rib portion (11) of the flat roof tile (1). By adopting a recessed shape (viewed from the rib side) inserted from above into the waterproof rib part (11), not only fixing the screw at the screw opening (32) but also the waterproof rib part (11). the insertion state of Te may be on improvement of the fixing strength of the tile fixing bracket (3) itself further.
[0016]
By the way, when the tile fixing bracket (3) is hooked on the waterproof rib portion (11) as described above, the rib hooking portion (33) is only the thickness as shown in FIGS. 4 (a) and 4 (b). Since the height is higher than that of the waterproof rib portion (11), a gap is generated between the back surface of the upper flat roof tile (1) positioned above the waterproof rib portion (11) and the waterproof rib portion (11). There is also the possibility of intrusion beyond 11).
[0017]
Therefore, in the invention of this application, for example, as illustrated in FIGS. 5A, 5B, and 6C and FIGS. 6A, 6B, and 6C, the waterproof rib portion (11) of the flat roof tile (1). , The height of the portion of the tile fixing bracket (3) where the rib hooking portion (33) is hooked is lowered, and when the rib hooking portion (33) is hooked on the portion, the waterproof rib portion (11) It is also a preferred embodiment that the height is substantially the same.
[0018]
In the embodiment of FIG. 5, the site of the waterproof rib (11) fits with rib engaging portion (33) is hooked is bent Ryakuyama type toward the eaves destination direction, the center piece (111) High The rib hook portion (33) is as thin as the thickness, and the left and right pieces (112) are inclined toward it.
[0019]
In the embodiment of FIG. 6, part of the waterproof rib (11) fits with rib engaging portion (33) is hooked is bent Ryakuyama type toward the eaves destination direction, the center piece (111) High Only the thickness of the rib hooking portion (33) is cut out by a thickness and the left and right pieces (112) remain horizontal.
[0020]
In any case, the rib hooking portion (33) of the roof tile fixing bracket (3) hooked on the central piece (111) is substantially the same height as the waterproof rib portion (11) of the flat roof tile (1). Thus, it is possible to suppress the formation of a gap between the waterproof rib portion (11) as described above and the back surface of the upper flat roof tile (1), and the waterproof effect can be further enhanced.
[0021]
By the way, the above waterproof structure is effective not only for rainfall but also for snowfall and snowmelt. Here, in snowy areas, snow stoppers are often provided on the roof tiles. However, if this snow stopper metal fitting and the roof tile fixing bracket (3) can be used integrally, the waterproof effect and the snow stopper can be used. The effect can be realized simultaneously and easily.
[0022]
Therefore, in the invention of this application, for example, as illustrated in FIGS. 7 to 10, the tile fixing bracket (3) itself is provided with a snow stopper (34) at the tip thereof, thereby realizing the above-mentioned. Can be achieved.
[0023]
