  However, if you do not use horizontal piers on the roof base, and place the roofing material directly on the roof base and fix it with screws or other fixtures, the former fixture is only for closing the nail holes. Therefore, if rainwater enters from the gap of the roof roofing material in the erected state and reaches the top of the asphalt roofing, the rainwater passes through the hole drilled in the asphalt roofing with a fixture and the field plate In the latter fixture, it is possible to close the hole opened in the asphalt roofing with the fixture, but it is not possible to close the nail hole, There was a problem that had to be solved, for example, it was impossible to deny the possibility that rainwater that had entered through the gap on the top side of the roof roof material would pass through the nail hole and reach the roof base.

  The present invention is based on the above prior art, and the rainwater passes through the hole drilled in the asphalt roofing with the fixture and reaches the field plate, or the rainwater that passes through the nail hole reaches the roof base side. In view of the above, a fixing tool body, which is a metal screw or a nail, is inserted into a resin tube that can penetrate a nail hole in a roof covering material, and the tip of the fixing tool body protrudes from the resin tube, and the protruding length is set on the roof. A fixing tool set to be shorter than the driving length of the fixing body to the ground side is driven through the nail hole of the roofing material placed on the roof base material into the roof base material, so that the lower end of the resin tube becomes the roof base material. After contact, it is compressively deformed, and the upper end of the resin tube is pushed by the head of the fixture body and gradually expands, and the lower end of the resin tube is crushed and expanded to adhere to the upper surface of the roof base and expand. The nail hole in roofing material at the upper end of the resin tube, and enables closing the hole drilled in the asphalt roofing at the lower end of the expanding resin tube, to solve the above problems.

In short, the present invention inserts a fixture body, which is a metal screw or nail, into a resin tube that can penetrate a nail hole in a roof covering material, and projects the tip of the fixture body from the resin tube. Is set to be shorter than the driving length of the fixture body on the roof base side, so that if this fixture is driven into the roof base through the nail hole of the roof covering placed on the roof base, the upper end of the resin tube Expands by the head of the fixture body and closes the nail hole, and the lower end of the resin tube expands and closes by pressing against the roof base and closes the hole opened in the asphalt roofing. It is possible to prevent rainwater from entering the side, and to prevent penetration from a hole opened in the asphalt roofing of rainwater entering from the other side.
However, the resin body does not come into contact with the roofing material due to the resin tube, so there is no electric corrosion on the body, and the corrosion resistance of the body can be improved. And since internal air is discharged | emitted and the state is maintained in connection with it, the further improvement of the corrosion resistance of a fixing tool main body can be aimed at.

  A roof covering material fixed by the roof covering material fixing tool according to claim 1, wherein a protrusion with a nail hole penetrating in the center is provided on the bottom surface of the bottom side of the tile body, and the protrusion has a bottom end in a state where it is laid down. The height above the upper surface of the groundwork is so high that even if there is no cross pier on the roof ground side, the length of the fixture protruding from the roofing material will be shortened. However, its practical effect is great.

Hereinafter, embodiments of the roof covering material according to the present invention will be described with reference to the drawings.
In the fixing device for roof covering material according to the present invention, a roof covering material 1 such as a general ceramic tile or a thin slate tile called “color vest”, “colonial” or the like is fixed to the roof base. Basically, a fixing tool body 11 which is a metal screw or nail is inserted into the resin tube 10, and the tip of the fixing tool body 11 is protruded from the resin tube 10, and the resin of the fixing tool body 11 is used. The protruding length L from the tube 10 is set to be shorter than the driving length L1 of the fixture main body 11 to the roof base W side.

  In Example 1 of the roof anchoring material fixing device according to the present invention, as shown in FIG. 1A, the resin tube 10 that can penetrate the nail hole 2 in the roof anchoring material 1 is fixed with a metal screw. The tool body 11 is inserted.

  The resin tube 10 is made of a resin such as silicon resin, which has elasticity and water resistance, weather resistance, and chemical resistance.

  The fixture body 11 is a countersunk screw made of metal such as steel or stainless steel, and has a head portion 13 at the upper end of the shaft portion 12, and the shaft portion 12 is inserted into the resin tube 10.

  The roof covering material 1 is a ceramic tile as shown in FIGS. 2 and 3, and an overlap portion 4 is provided on one side of the substantially square plate-like tile body 3, an underlap portion 5 is provided on the other side, and the head side. A flat roof tile with sag 6, two nail holes 2, 2 are provided through the bottom side, and two bottom projections 7, 7 are provided on the bottom side of the bottom side. It is set at a position below the lower surface of the wrap portion 5.

  The nail holes 2 and 2 pass through the centers of the protrusions 8 and 8 provided on the lower surface of the roof tile body 3, and the upper openings of the nail holes 2 and 2 are the bottoms of the recesses 9 and 9 formed on the upper surface of the roof tile body 3. The lower ends of the protrusions 8 and 8 are set at a position above the upper surface of the roof base W in the installed state, preferably at the same level as the lower surface of the underlap portion 5.

  Then, as shown in FIG. 4, the roof covering material 1 is placed on the asphalt roofing A in the roof base W, and the lower end of the fixture main body 11 of the fixing tool penetrating the nail hole 2 is passed through the asphalt roofing A. By screwing it into the base plate N, the resin tube 10 is compressed and deformed while twisting after the lower end of the resin tube 10 contacts the upper surface of the asphalt roofing A (see FIG. 1 (b)). As the head 13 of the main body 11 is buried, the upper end of the resin tube 10 gradually expands, the lower end of the resin tube 10 is crushed and expanded, and is in close contact with the upper surface of the asphalt roofing A.

  In the second embodiment of the roofing fixture according to the present invention, as shown in FIG. 5A, the resin tube 10 that can penetrate the nail hole 2 in the roofing fixture 1 is fixed with a metal nail. The tool body 11 is inserted.

  The resin tube 10 is made of a resin such as silicon resin, which has elasticity and water resistance, weather resistance, and chemical resistance.

  The fixture body 11 is a metal nail (such as a screw nail in the drawing, but it may be a straight nail) such as steel or stainless steel, and has a head 13 at the upper end of the shaft portion 12. Thus, the shaft portion 12 is inserted into the resin tube 10.

  The roof covering 1 is a thin slate tile as shown in FIG. 6 and has a plurality of nail holes 2, 2.

  The nail holes 2, 2... Are formed along the bottom end of the roof roof material 1 below in the installed state.

  Then, as shown in FIG. 7, the roof covering material 1 is placed on the asphalt roofing A in the roof base W, and the lower end of the fixing body 11 of the fixing tool penetrating the nail hole 2 is passed through the asphalt roofing A. By driving it into the base plate N, the resin tube 10 is compressed and deformed after its lower end comes into contact with the upper surface of the asphalt roofing A (see FIG. 5 (b)). It is pushed by the head 13 and gradually expands, and the lower end of the resin tube 10 is crushed and spreads, and comes into close contact with the upper surface of the asphalt roofing A.

In other words, in the fixtures of Examples 1 and 2, the upper expanding portion 14 of the resin tube 10 is located between the head 13 of the fixture body 11 and the lip portion of the nail hole 2 in the roof covering 1, The nail hole 2 is closed without bringing the head 13 into contact with the roofing material 1, and the shaft portion 12 of the fixture body 11 is not brought into contact with the roofing material 1 by the resin tube 10. The hole drilled in the asphalt roofing A is closed by the fixture body 11.
Further, even if the roof covering 1 is broken and dropped due to an earthquake, the fixture according to the present invention remains as it is and remains in the state of closing the hole opened in the asphalt roofing A, so that rain leakage is suppressed as much as possible. It becomes possible.

In particular, in the case of FIG. 4, since there are protrusions 8 and 8 on the roof base material 1, the roof base material 1 is directly grounded on the roof base W without providing the crosspieces on the roof base W. Even if the fixture body 11 is placed and fixed, the protruding length of the fixture body 11 from the roof covering material 1 is shortened, so that the downward sliding due to the weight of the roof covering material 1 can be suppressed and the horizontal pier is fixed. This eliminates the need for the above work, shortens the construction period and reduces construction costs, improves the air permeability between the roof covering 1 and the roof base W, and nails and screws for fixing the horizontal pier. As a result, it is possible to perform the laying work without making a hole in the asphalt roofing A, and it is possible to construct a tile roof having an excellent waterproof function.
In addition, if the roof covering 1 has the recesses 9, the length of the fixture itself can be shortened.

  In FIG. 1 (b) and FIG. 4, the resin tube 10 is expressed as a state in which only the upper expanding portion 14 and the lower expanding portion 15 are formed, but this is not simply described. Actually, by screwing the fixing device main body 11 which is a screw, the state where the torsional deformation remains particularly in the downward expanding portion 15 is shown in FIGS. 5B and 7. Then, since the fixing tool body 11 that is a nail is only driven in, the resin tube 10 is not twisted and deformed.

  Further, the fixture body 11 in the first and second embodiments is a screw when the roof covering 1 is a ceramic tile, and a nail when the roof tile 1 is a thin slate tile, but it is either a screw or a nail. May be.
