Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in the attachment of plate-like roofing materials such as roof tiles and roof tiles having locking projections for locking horizontal rails on the back side of the ridge, and particularly to plate-like roofs. TECHNICAL FIELD The present invention relates to a holder having an increased material holding strength.

[0002]

2. Description of the Related Art Conventionally, plate-like roofing materials such as roof tiles and roof tiles have characteristics such as corrosion resistance, fire resistance, texture and traditional beauty, and are widely used mainly as roofs of general houses. Problems such as slippage, dropout, scattering, and water leakage have been pointed out in each typhoon or earthquake. Many of these problems are due to the fixing structure of this type of plate-shaped roofing material, so that the ridge ends of the roof tiles are simply locked (hooked) on the horizontal rails, or fixed (holding) using nails or copper wires together. ) With the structure, the above-mentioned problems cannot be solved, and therefore a holder capable of securely holding the holder is required.

Therefore, a proposal has been made for a roof tile fixing metal fitting described in Japanese Utility Model Laid-Open No. 6-20665, but this metal fitting is roughly described as a fixing portion to a roof base and a parallel extending in the eaves direction. And a ridge end of the roof tile is sandwiched by the sandwiching member to prevent the roof tile from rising.

[0004]

However, in the above-mentioned metal fitting, since the ridge end of the roof tile is only sandwiched by the sandwiching member, the effect of holding external force in the flow (eave tip) direction cannot be expected. Further, since it is not described in the above-mentioned publication whether or not this metal fitting is used together with the above-mentioned cross rail for locking the ridge end of the roof tile, it is presumed that the metal fitting is used alone. Even if it is done, since there is no positional relationship between the cross rail and the metal fittings, there is a high possibility that the builder will vary the holding strength of the roof tile. Further, in the publication, the conventional fixing method using nails or copper wires described above is "sufficient in terms of preventing roof tiles from slipping and slipping off." It is obvious that the structure does not have sufficient mounting strength.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and holds a plate-like roofing material such as a roof tile or a roof tile having a locking projection on the back side of the ridge edge on a roof substrate. A retainer for a plate-shaped roofing material comprising a metal cross rail and a holding metal fitting, wherein the cross rail is an upright engagement portion with respect to a roof base surface, a connecting portion, and the plate roof. A protrusion located substantially parallel to the locking portion at a distance substantially equal to the thickness of the locking protrusion of the material, and a fixing portion, wherein the pressing metal member presses the ridge end surface of the plate-shaped roof material. The present invention relates to a holder for a plate-shaped roofing material, comprising: a pressing portion, an abutting portion that abuts on a protrusion of the horizontal rail, and a superimposing portion that overlaps with a fixing portion of the horizontal rail.
