Description

The present invention relates to a roofing structure for a roof material, in which a suspension for attaching to a thin plate-like roof material to be laid on the ground under the roof is attached, and further, another thin plate-like roof material is wound toward the ridge side. .

In general, roof tiles are spread on the roof of a house or the like, but in recent years, a thin roof material has been developed along with the weight reduction and design of the roof tiles (see, for example, Patent Document 1). .)

For this reason, recently, a roofing structure of a roof material using a suspension attached to such a thin plate-like roof material has also been proposed (for example, see Patent Document 2).

There are various types of thin plate-like roof materials such as a flat plate and a corrugated plate.

FIG. 4 is a partial perspective view showing a roofing structure of a roof material using a hanging element attached to a conventional thin plate-like roof material, and FIG. 5 is an enlarged partial cross-sectional view of the main part shown in FIG. It is.

The suspension 100 includes a substrate body 101 formed of a metal plate, a presser piece 102 whose tip is folded upward in a substantially U-shaped cross section, and an attachment hole 103 formed on the rear end side of the substrate body 101. Prepare. Further, the pressing piece 102 forms a resilient portion 112 toward the inside.

Then, the rear end of the suspension 100 is positioned at the ridge side end of the eaves-like thin roofing material 200 that is wound on the base S, and a fixing tool 104 such as a nail or a screw is passed through the attachment hole 103. The eaves-side thin plate-like roofing material 200 is spread over the base S while being fixed to the base S.

Further, in order to spread the thin roof material 300 on the ridge side, if the eaves side end of the thin roof material 300 is inserted into the presser piece 102 of the already attached suspension 100, it is guided to the elastic portion 112. The ridge-side thin roofing material 300 is fixed to the base S in the same manner as described above, and the ridge-side thin roofing material 300 is partially overlapped with the eaves-side thin roofing material 200. In this state, it is spread on the base S.

However, the conventional roofing structure using the hanging member 100 has the following problems.

That is, since the head 114 is formed on the fixture 104 such as a nail or a screw, as shown in FIG. Is pressed by the elastic portion 112 and the bottom surface of the ridge is in contact with the head portion 114 in a two-point support state.

Therefore, when the thin roof-like roof material 300 on the ridge side is bent in the direction of the arrow P by wind or the like, the upper surface of the eaves side end is pressed only by the point of contact with the elastic portion 112. There was a problem that the edges were easily rattled.

In addition, resin roofing materials such as FRP roofing materials are harder to break than cement-based roofing materials, have strength, and can be formed with a reduced thickness. However, the roof material, which is difficult to break, is likely to bend with respect to the load applied to the local area, and the portion that is locked by the suspension is particularly easy to bend.

An object of the present invention is to solve such a problem, and provides a roofing structure of a roofing material that can be securely attached by preventing rattling of the thin roofing material .

To achieve the above objective,
The roofing structure of the roofing material according to claim 1 is obtained by attaching a hanging element to a thin plate-like roofing material wound on the ground under the roof and further spreading another thin-plate-like roofing material toward the ridge side. A roofing structure of a roofing material, wherein the suspension is formed on a substrate body formed of an elastic material, a presser piece whose front end is folded upward in a substantially U-shaped cross section, and a rear end side of the substrate body And formed with a guide inclined surface for guiding the roof material on the lower surface of the pressing piece, and a protrusion for pushing up the roof material on the upper surface of the substrate body , The thin plate-like roof material to be inserted into the presser piece is pressed by the guide inclined surface on the upper surface of the eave side end, and the lower surface of the eave side end penetrates the protrusion and the mounting hole and serves as a base. Being struck in a three-point support state, in contact with the head of the fixture to be fixed And features.

The roofing structure of the roof material according to a second aspect is the one according to the first aspect, wherein the guide inclined surface of the pressing piece is formed by a bent piece formed by cutting and raising.

According to a third aspect of the roofing structure of the roof material according to the first aspect, the guide inclined surface of the presser piece is formed by a rib bulging downward from the presser piece.

The present invention has the following effects.
According to the roofing structure of the roof material according to claim 1, a guide inclined surface for guiding the roof material is formed on the lower surface of the presser piece of the suspension element , the substrate body is formed of an elastic material, and the substrate body Since the upper surface is formed with a protrusion that pushes up the roofing material, the thin roofing material that is inserted into the holding piece is supported in a state where the entire eave side end is sandwiched between elastic materials, The lower surface is rolled in a three-point support state in contact with the protrusion and the head of the fixture .

Therefore, the thin roof-like roofing material on the ridge side receives a load due to wind or the like, and the eaves-side end supports it by the whole elastic action even if it tries to bend. It is possible to reliably prevent the eaves side end of the material from bending downward and causing backlash.

According to the roofing structure of the roof material according to the second aspect, in the first aspect, the guide inclined surface of the presser piece is formed by the bent piece formed by cutting and raising, so that it can be easily formed.

According to the roofing structure of the roof material according to claim 3, in claim 1, the guide inclined surface of the presser piece is formed by a rib that bulges downward from the presser piece. Can be increased.

The roofing structure of the roof material according to the present invention will be described below with reference to the drawings.

FIG. 1 is a partial perspective view showing a roofing structure according to the present invention in use, and FIG. 2 is an enlarged partial cross-sectional view of the main part shown in FIG.

The hanging element A used in the roofing structure of the roofing material according to the present invention is to be attached to a resin roofing material such as an FRP roofing material wound on the roof base S, or other thin plate-like roofing material Y. A substrate body 1 made of an elastic material, a pressing piece 2 whose tip is folded upward in a substantially U-shaped cross section, and a mounting hole 3 formed on the rear end side of the substrate body 1. A guide inclined surface 21 that guides the roof material Y is formed on the lower surface of the piece 2, and a protrusion 11 that pushes up the roof material Y is formed on the upper surface of the substrate body 1.

The hanging element A shown in the present embodiment is formed by integrally forming the substrate main body 1 and the pressing piece 2, and is formed by bending an elastic leaf spring piece, for example.

In addition, it is desirable to form the substrate body 1 by curving the entire substrate body 1 instead of a flat plate because the elastic force can be further increased.

The sheet-like roof material A on the eaves side is spread over the foundation S.

Further, in order to spread the thin roof material Y1 on the ridge side, if the eaves side end of the thin roof material Y1 is inserted into the presser piece 2 of the already attached suspension A, it is guided to the guide inclined surface 21. It is inserted into the back while being held, and is sandwiched and locked between the inclined guide surface 21 and the protrusion 11.

Then, the ridge-side roof material Y1 is fixed to the base S in the same manner as described above, and the ridge-side roof material Y1 is partially overlapped with the eaves-side thin roof material Y. S on the S.

As described above, according to the roofing structure of the roofing material according to the present invention, the guide inclined surface 21 for guiding the roofing material Y is formed on the lower surface of the presser piece 2 of the suspension A, and Since the projection 11 that pushes up the roof material Y is formed on the upper surface, the thin plate-like roof material Y1 inserted into the presser piece 2 is pressed by the guide inclined surface 21 on the upper surface of the eave side end, The lower surface is scratched in a three-point support state in contact with the protrusion 11 and the head 41 of the fixture 4.

Therefore, the thin roof-like roof material Y1 on the side of the wing is subjected to a load by wind or the like, and the eaves side end is supported by the whole elastic action even if it is bent in the direction of the arrow P. It is possible to reliably prevent the eaves-side end of the thin sheet-like roof material Y1 from being bent downward and causing rattling.
