Description

  The present invention relates to a structure for attaching a roof material to be laid on a field board to form a roof of a house.

  Conventionally, a roof base is formed by placing a panel provided with a heat insulating material between an upper plate and a lower plate made of plywood or the like on a roof structure material as a base plate. A roof of a building is formed by spreading a roofing material on a base (see, for example, Patent Document 1). However, when a wooden panel is used, the weight is very large and the workability is low.

  Therefore, it has been proposed by the present applicant to use a sandwich panel formed by filling a core material between two metal plates as a base plate (for example, Japanese Patent Application No. 2002-273969). In the case of a panel using such a metal plate, it is possible to reduce the weight even though the strength such as bending strength is larger than that of the above-mentioned wooden panel. It is possible to reduce the number by arranging them at a large interval, and it is possible to improve the workability and reduce the weight of the entire roof.

By the way, the roofing material placed on the field board is driven from the upper surface (surface) with a fixing tool such as a screw or a tex, and the fixing tool is driven through the field board to the roof structure material such as a rafter. By being fixed. However, if the number of rafters is reduced as described above, the fixing tool cannot be driven in. Therefore, the fixing tool is driven only into the field plate to fix the roofing material. There was a risk that the mounting strength of the roofing material would be reduced.

It is possible to make it difficult for the tool 8 to be removed from the base plate 5, and the fixing member 8 can firmly fix the roof material 7 to the base plate 5, so that the attachment strength of the roof material 7 is not easily lowered. In addition, the operation of driving the fixture 8 can form the locking portion 9 and lock the locking portion 9 to the locked portion 13, so that the work of firmly attaching the roofing material 7 can be easily performed. Is something that can be done.

  According to the present invention, the fixing member can be made difficult to come off from the field plate by the locking of the locking part to the locked portion, and the roof material can be firmly fixed to the field plate by this fixing tool. The attachment strength of is difficult to decrease.

  Hereinafter, the best mode for carrying out the present invention will be described.

  In the present invention, the field board 5 is formed of a panel 4, which has been conventionally used as a building material such as a wall panel, a roof panel, and a floor panel. The panel 4 may be formed by providing the metal plate 1 on at least one side of the core material 3, for example, the core material 3 between the two metal plates 1 and 2 made of a front plate and a back plate. A sandwich panel formed by filling and bonding can be used. The metal plates 1 and 2 can be formed of stainless steel plate, galvanized steel plate, painted steel plate, galvalume steel plate (zinc-aluminum alloy plated steel plate), and the core material 3 is a resin foam such as phenol foam or urethane foam. Although it can form with inorganic fiber bodies, such as glass wool and rock wool, it is not limited to these. Moreover, although the thickness of the metal plates 1 and 2 can be 0.2-1.6 mm and the thickness of the core material 3 can be 15-200 mm, it is not limited to these. Furthermore, as the panel 4, a panel connected by concavo-convex fitting may be used.

  In the present invention, conventionally used roofing material 7 can be used as it is. The roofing material 7 shown in FIG. 2 is formed in a substantially plate shape by bending a metal plate similar to the above, and the eaves side end of the roofing material 7 (below the roof gradient). A fitting recess 20 is formed on the side of the roof material 7 and the surface side of the roof material 7 (upper surface side) is located near the ridge side end of the roof material 7 (upward with respect to the slope of the roof). The fitting convex part 21 which protrudes is provided. Furthermore, the ridge side end of the roof material 7 is formed as a fixed piece 23, and is extended to the ridge side from the fitting convex portion 21. In addition, the roofing material 7 shown in FIG. 2 is an example, and may be formed of other materials and shapes.

  The fixture 8 used in the present invention is made of a metal such as stainless steel or brass, and is shaped like a screw or a screw as shown in FIGS. 3 (a) and 3 (b). The screw portion 25 of the portion and the head portion 26 of the rear end portion are configured. The drill portion 10 has a sharp pointed tip and is formed in a drill-like shape. With the drill portion 10, the fixed piece 23 of the roofing material 7, the metal plate 1 of the panel 4, and the core material 3 are formed by the drill portion 10. It can be perforated. Further, a screw groove 11 (male screw) is formed on the outer surface of the screw portion 25, and the groove width L of the screw groove 11 is formed to be smaller than the thickness of the metal plate 1 serving as the surface plate of the panel 4. ing. Furthermore, the outer diameter (the outer diameter of the thread 12) D of the screw portion 25 is formed to be about 0.5 to 2.0 mm larger than the outer diameter d of the drill portion 10, and this screw portion 25 is a fixture. When the screw 8 is screwed into the base plate 5, the metal plate 1 of the base plate 5 in the peripheral portion of the fixture 8 is pressed downward so as to be bent so as to be bent.

  And in attaching the roofing material 7 in this invention, it carries out as follows. First, the panel 4 is placed in a state where the core material 3 is lower than the metal plate 1 by mounting and fixing the panel 4 on the structural material 6 of the building composed of a purlin, rafters, and the like. A roof base as a base plate 5 is formed. At this time, the panel 4 can be fixed to the structural member 6 by inserting a text. Further, a plurality of panels 4 can be arranged on the structural material 6 to form a roof base, but if the panels 4 can be connected by uneven fitting, adjacent panels 4 are connected by uneven fitting. To do. Next, the roof material 7 is placed on the panel 4 fixed to the structural material 6. At this time, the fixing piece 23 provided on the roof material 7 is brought into contact with the metal plate (upper surface plate) 1 on the surface side of the panel 4. Next, the roofing material 7 is fixed on the panel 4 by driving the fixing tool 8 into the fixing piece 23 from the surface side of the roofing material 7. At this time, the fixture 8 passes through the fixing piece 23 and the metal plate 1 of the panel 4 and reaches the core material 3, but it is not necessary to penetrate the core material 3 or the metal plate (lower surface plate) 2 on the back surface side. However, it does not deny that the fixture 8 penetrates the core material 3 or the metal plate 2 on the back surface side.

  After fixing one roofing material 7 as described above, another roofing material 7 is fixed to the surface of the panel 4 in the same manner as described above. At this time, the roof materials 7 and 7 adjacent to each other in the eave building direction are connected so that the fitting concave portion 20 of the roof material 7 on the ridge side is fitted to the fitting convex portion 21 of the roof material 7 on the eave side. It is. By sequentially constructing the roofing material 7 from the eave side to the ridge side in this way, as shown in FIG. 4, a plurality of roofing materials 7 are attached to the surface of the panel 4 to form a roof. It is something that can be done.

  And in this invention, the attachment strength of the roofing material 7 becomes difficult to fall by attaching the roofing material 7 to the field board 5 as mentioned above. That is, when the fixing tool 8 is screwed into the fixing piece 23 of the roofing material 7 and punched in, the drilling portion 10 at the tip portion drills the fixing piece 23, the metal plate 1 on the surface side of the panel 4, and the core material 3. However, since the outer diameter of the drill portion 10 is smaller than the outer diameter of the screw portion 25 of the fixing tool 8, the metal plate on the surface side is formed by the drill portion 10. The hole formed in 1 is smaller than the outer diameter of the screw portion 25. Further, the groove width L of the screw groove 11 formed in the screw portion 25 is formed smaller than the thickness of the metal plate 1 on the surface side, and the metal plate 1 at the peripheral edge of the hole formed in the drill portion 10 is screwed. The groove 11 can be prevented from entering. Therefore, when the fixing tool 8 is screwed into the fixing piece 23 of the roofing material 7 and driven in, the peripheral portion of the hole drilled in the metal plate 1 from the drill portion 10 is the upper side at the screw portion 25 (the driving portion 28). As a result, the metal plate 1 is bent downward (inward of the panel 4) in the vicinity of the periphery of the screw portion 25 of the fixture 8, as shown in FIG. And the latching | locking part 9 is formed in this curved part. Further, the tip of the locking portion 9 formed in this way is engaged in a state where a part (corner portion) thereof is inserted into the screw groove 11 formed on the peripheral surface of the screw portion 25 of the fixture 8. The locking portion 13 is locked to the thread 12 formed as the locking portion 13, whereby the locked portion 13 of the fixing tool 8 is locked to the locking portion 9, and the fixing tool 8 is removed from the base plate 5. It becomes difficult. And since it becomes difficult to remove the fixture 8 from the field board 5 in this way, the roof material 7 can be firmly fixed to the field board 5 by the fixture 8, and the attachment strength of the roof material 7 becomes difficult to fall. Is. When the fixing tool 8 is screwed into the fixing piece 23 of the roofing material 7 and driven in, the peripheral portion of the hole drilled in the fixing piece 23 by the drill portion 10 is pressed from above by the screw portion 25, and the screw portion The fixing piece 23 is also bent downward in the vicinity of the periphery of 25 and locked to the screw portion 25.

  5 (a) and 5 (b) show other examples of the fixture 8. FIG. In the fixing device 8 shown in FIG. 3, the screw portion 25 is formed to be slightly longer, and a pressing portion 27 whose outer diameter gradually decreases as the screw portion 25 becomes lower (closer to the screw portion 25). Has been. Other configurations are the same as those in FIG.

  The fixture 8 shown in FIGS. 5A and 5B is also used in the same manner as described above. That is, after placing the roofing material 7 on the panel 4 fixed to the structural material 6, the fixing tool 8 is driven into the fixing piece 23 and the panel 4 from the surface side of the roofing material 7. 7, the roofing material 7 is fixed on the panel 4, but when the fixture 8 is screwed into the fixing piece 23 of the roofing material 7 and driven, the metal plate 1 is formed by the drill portion 10. The peripheral edge of the hole drilled in can be pressed from the upper side (surface side) by both the screw part 25 and the pressing part 27, and the locking part 9 is beautifully curved along the outer shape of the pressing part 27. It can be formed, and the locking portion 9 can be securely locked to the locked portion 13 so that the locking portion 9 does not become a distorted shape. Therefore, the fixture 8 is further detached from the panel 4. It is difficult to fix the roofing material 7 on the panel 4 more firmly. A. When the fixture 8 is screwed into the fixing piece 23 of the roofing material 7 and driven, the peripheral edge of the hole drilled in the fixing piece 23 by the drill portion 10 is pressed from above by the screw portion 25 and the pressing portion 27. The fixing piece 23 is also bent downward in the vicinity of the periphery of the screw portion 25 and the pressing portion 27.

FIG. 8 shows a reference example . In this reference example , a roof slate such as a fiber-reinforced cement tile is used as the roof material 7. As shown in FIG. 9, such a roofing material 7 is formed in a pentagonal shape in plan view having a top portion 7 a and a shoulder portion 7 b, and has a waterproof groove 7 c in the lateral direction, having a width dimension of 910 mm, from the front end Although the dimension to the top part 7a can be 414 mm, the dimension from the front end to the shoulder part 7b is 332 mm, and the thickness is 4.5 mm, the shape and dimensions of the roofing material 7 are not limited to the above.

Further, in this reference example , as shown in FIGS. 10 (a) and 10 (b), as the fixture 8, a plurality of protrusions 8a are provided on the surface of the pressing portion 27 of the fixture 8 in FIGS. 5 (a) and 5 (b). Something is used. This protrusion 8a is formed in a line shape that is long in the vertical direction along the surface of the pressing part 27, and the protrusion dimension from the surface of the pressing part 27 is 0.5 to 1.0 mm, the adjacent protrusion 8a, Although the dimension between 8a can be 0.5-1.0 mm, it is not limited to these. Other configurations are the same as those in the above embodiment.

And also in this reference example , the roofing material 7 can be constructed similarly to the above. That is, after placing the roofing material 7 on the panel 4 fixed to the structural material 6, the fixing tool 8 is driven into the roofing material 7 and the panel 4 from the surface side of the roofing material 7. As shown in FIG. 1, the roofing material 7 is fixed on the panel 4, and the metal plate 1 is placed downward (inward of the panel 4) in the vicinity of the periphery of the screw portion 25 of the fixture 8 in the same manner as described above. The engaging portion 9 is formed at the curved portion, and a tip (a corner portion) of the engaging portion 9 is formed on the peripheral surface of the screw portion 25 of the fixture 8. 11 is locked to the thread 12 formed as the locked portion 13, and the locked portion 13 of the fixture 8 is locked to the locking portion 9. This makes it difficult for the fixture 8 to come off the base plate 5. And since it becomes difficult to remove the fixture 8 from the field board 5 in this way, the roof material 7 can be firmly fixed to the field board 5 by the fixture 8, and the attachment strength of the roof material 7 becomes difficult to fall. Is. Further, when the fixing tool 8 is screwed into the roofing material 7, the inner surface of the hole into which the fixing tool 8 is screwed can be screwed in with the projection 8 a, and a gap is generated between the fixing tool 8 and the roofing material 7. The roof material 7 can be attached without rattling, and the frictional force between the roof material 7 and the fixture 8 screwed into the roof material 7 can be increased by the protrusion 8a. It is difficult to cause the fixture 8 to loosen and prevent the fixture 8 from being loosened, thereby preventing the fixture 8 from falling off the roof material 7 and the panel 4. In addition, as shown in FIG. 8, in the several roof material 7 attached on the panel 4, the roof materials 7 and 7 adjacent to an eaves-ridge direction are constructed, overlapping one part.
