  Below, the supporting member concerning an embodiment of the invention is explained in detail based on a drawing. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a cross-sectional view showing a state in which a support member according to Embodiment 1 of the present invention is fixed to a base structure 1 of a roof. FIG. 2 is an exploded perspective view of the support member shown in FIG. The support member according to the first embodiment includes a support roof 2, a support bracket 4, and a cover member 6.

  The supporting tile 2 is arranged by replacing a part of the roof tile 10 that is a roofing material in a tiled roof. Accordingly, the support roof 2 has substantially the same shape as that of the portion from which one or more roof tiles 10 are removed in plan view. An opening 21 is formed in the support tile 2.

  FIG. 3 is a perspective view of the support fitting 4. FIG. 4 is a plan view of the support fitting 4. FIG. 5 is a front view of the support fitting 4. FIG. 6 is a side view of the support fitting 4. The support fitting 4 is produced, for example, by processing a steel plate into a sheet metal.

  The fixed portion 41 has side plate portions 41b bent in the same direction at both ends of a base portion 41a having a flat plate shape, and has a U-shaped cross section as a whole. A communication hole 41c is formed in the base 41a.

  The overhang portion 42 is formed so as to overhang both sides of the fixed portion 41. Specifically, it is formed at the tip of the side plate portion 41 b of the fixing portion 41. As shown in FIG. 4, in the plan view, the width of the overhanging portion 42 is larger than the width of the fixing portion 41 in the direction parallel to the side of the base portion 41 a where the side plate portion 41 b is formed (the direction indicated by the arrow X). Is bigger. The overhanging portion 42 protrudes on both sides of the fixed portion 41 in the direction indicated by the arrow X.

  As illustrated in FIG. 5, the overhang portion 42 is formed by bending a flat plate member. By this bending, the projecting portion 42 is provided with an inclined surface 42a facing the fixed portion 41 side. A guide hole 44 that penetrates the overhang portion 42 is formed in the inclined surface 42a. The penetration direction of the guide hole 44 is a direction substantially perpendicular to the inclined surface 42a. Therefore, the fixing screw 5 that passes through the guide hole 44 is restricted in the direction in which the fixing screw 5 is away from the fixing portion 41 in the direction along the fixing surface to which the fixing portion 41 is fixed.

  The guide hole 44 is formed in a portion of the projecting portion 42 that protrudes on both sides of the fixed portion 41 in the direction indicated by the arrow X. In other words, it can be said that the guide hole 44 is formed in a region that does not overlap with the projected portion where the fixing portion 41 is projected in the penetrating direction of the guide hole 44.

  The support metal fitting 4 is fixed to the base structure 1 of the roof so that the fixing portion 41 is passed through the opening 21 of the support tile 2. Here, as a foundation structure 1 for a roof, a general structure in which a rafter 11, a field board 12, and a roofing 13 are layered will be described as an example.

  First, the fixing base 3 is fixed on the base structure 1. The fixing base 3 is fixed on the base structure 1 by screwing fixing screws 14 into the rafters 11 and the base plate 12. The fixed base 3 has a larger planar shape than the support bracket 4. As a result, the rafter 11 and the fixing base 3 can be securely stacked, and the fixing screw 14 can be screwed into the rafter 11.

  The overhanging portion 42 of the support metal 4 is brought into contact with one surface (fixed surface) of the fixed base 3, and the fixing screw 5 is passed through the guide hole 44 and screwed into the fixed base 3 and the base plate 12. 4 is fixed on the roof. Since the fixing position of the support metal fitting 4 is limited by the position of the opening 21 of the support roof tile 2, the fixing screw 5 cannot always be screwed into the rafter 11.

  The cover member 6 is provided so as to cover the opening 21 in a state where the support tile 2 and the support fitting 4 are fixed on the roof. A communication hole 6 a is formed in the cover member 6. With the cover member 6 covering the opening 21, the communication hole 6 a formed in the cover member 6 and the communication hole 41 c formed in the fixing portion 41 of the support metal 4 communicate with each other.

  The vertical rail 7 is fastened on the roof by the bolt 15 and the nut 16 that are passed through the communication holes 6a and 41c that communicate with each other. Equipment equipment (not shown) such as a solar cell module or a solar heat utilization water heater is fixed to the vertical rail 7.

  As described above, in the support member according to the first embodiment, the fixing screw 5 penetrating through the guide hole 44 is regulated in a direction in which the penetrating direction is away from the fixing portion 41. Screwed diagonally. When the fixing screw 5 is passed through the base plate 12, the length in which the fixing screw 5 is screwed into the base plate 12 is increased by screwing the fixing screw 5 obliquely rather than screwing the fixing screw 5 perpendicularly to the base plate 12. be able to.

  Therefore, even when the fixing screw 5 is not screwed into the rafter 11, the pullout strength at the portion screwed into the base plate 12 can be improved, and the fixing screw 5 can be more firmly fixed on the roof. By fixing the support bracket 4 firmly, it is possible to improve the fixing strength of the equipment that is fixed on the roof via the support bracket 4.

  Further, when the fixing bracket 5 is screwed obliquely with respect to the base plate 12, when the support metal fitting 4 is pulled in a direction perpendicular to the base plate 12, the pulling load to the fixing screw 5 by load distribution There is also an effect of reducing. Thereby, when the fixing screw 5 is screwed in, the screw hole formed in the base plate 12 becomes difficult to expand, and a decrease in fixing strength due to deterioration over time can be suppressed.

  In the first embodiment, the inclined surface 42a and the guide hole 44 are formed so that the penetration direction of the fixing screw 5 is away from the fixing portion 41. However, the penetration direction of the fixing screw 5 is fixed. Even in the direction approaching the portion 41, the fixing screw 5 can be screwed into the base plate 12 obliquely. However, in this case, it is difficult to perform the operation of screwing the fixing screw 5 through the opening 21 after the support tile 2 is installed on the roof.

  When a new house is constructed, the installation of the support tile 2 and the installation of the support bracket 4 may be performed by different operators. Then, it is desirable that the support metal fitting 4 can be fixed even after the support tile 2 is installed. In the first embodiment, the support metal fitting 4 can be fixed after the support tile 2 is installed by setting the penetration direction of the fixing screw 5 to be a direction away from the fixing portion 41.

  Further, even when the distance between the guide holes 44 is larger than the length of each side of the opening 21 and the guide holes 44 are hidden by the support tile 2 in plan view, the penetration direction of the fixing screw 5 is fixed. By setting the direction away from the portion 41, the fixing screw 5 can be inserted into the guide hole 44 if the fixing screw 5 or a tool for screwing it is inserted obliquely through the opening 21 of the support tile 2. Therefore, even if the size of the protruding portion 42 of the support metal 4 in plan view is made larger, the support metal 4 can be fixed after the support tile 2 is installed. Moreover, it is also possible to improve the section modulus of the fixing portion 41 by forming the overhanging portion 42 large.

  When the support bracket 4 is fixed after the support tile 2 is installed, the angle of the inclined surface 42a of the overhanging portion 42 with respect to the base plate 12 is such that the angle of the fixing screw 5 rises about 60 ° from the roof surface. It is desirable that the angle is about 30 °. Also, the length of the fixing screw 5 is (distance from the base plate 12 to the opening 21) ÷ cos 30 ° or more so that the fixing screw 5 does not easily fall from the opening 21 of the support tile 2 during the driving operation. It is desirable that the length be.

  Moreover, the shape of the fixing | fixed part 41 and the overhang | projection part 42 is not restricted to what was illustrated above. For example, the projecting portions 42 projecting on both sides of the fixed portion 41 may be connected to each other and formed in a single plate shape. Further, the material of the support fitting 4 may be aluminum to improve the corrosion resistance. Further, as shown by a two-dot chain line in FIG. 5, an adhesive waterproof sheet 45 such as butyl may be attached to the back surface of the support metal fitting 4 to improve the waterproof property. In addition, the inclined surface 42 a may not be provided, and the through direction of the fixing screw 5 may be regulated in the direction away from the fixing portion 41 only in the through direction of the guide hole 44.

  FIG. 7 is a plan view of the support fitting 4 according to the modification. FIG. 8 is a front view of the support fitting 4 according to the modification. FIG. 9 is a side view of the support fitting 4 according to the modification. In the support fitting 4 according to this modification, the width of the fixed portion 41 and the width of the overhang portion 42 are equal in the direction parallel to the side of the base portion 41a where the side plate portion 41b is formed (the direction indicated by the arrow X). It has become. Therefore, the guide hole 44 is formed in a region overlapping with the projected portion obtained by projecting the fixing portion 41 in the penetrating direction of the guide hole 44.

  Therefore, the fixing portion 41 becomes an obstacle to let the fixing screw 5 pass through the guide hole 44. Therefore, in the present modification, an opening is formed in a region of the fixed portion 41 that overlaps with an extended portion that extends the guide hole 44 toward the fixed portion 41 along the through direction of the guide hole 44 (the through direction of the fixing screw 5). 46 is formed.

  Through this opening 46, the fixing screw 5 and a tool for screwing it can reach the guide hole 44. Further, the edge portion of the opening 46 also functions as a guide portion for preventing the fixing screw 5 and the tool from being displaced when the fixing screw 5 is screwed.

  FIG. 10 is a view showing a state in which the support fitting 4 is fixed to the slate roof material 9. As shown in FIG. 10, the members can be shared by fixing the support metal fitting 4 directly to the slate roofing material 9. In addition, by pulling the fixing screw 5 diagonally, the pulling strength can be improved, and the fixing strength of the equipment installed on the roof can be improved. In this case, the surface of the slate roof material 9 becomes a fixed surface with which the overhanging portion 42 abuts. Further, the vertical rail 7 (see also FIGS. 1 and 2) is directly fixed to the support bracket 4.

  As described above, the support member according to the present invention is useful as a support member for fixing equipment on the roof.
