Description

  The present invention relates to a flat roof material that is laid on a roof of a house or the like.

  As shown in FIG. 6A, the flat roof material 1 used to form the roof 30 of a building such as a house is from the eave side (lower side in the tilt direction) to the ridge side (upper side in the tilt direction). ), And then rolled and constructed to wrap sequentially. In particular, in an area where wind is strong, various methods have been studied in order to prevent the flat roof material 1 from turning up from the lower side in the inclination direction due to strong wind.

  Specifically, as shown in FIG. 6B, first, the flat roof material 1 in which a plurality of nail holes 40 are formed is overlaid from the eaves side toward the ridge side. Next, the fixture 3 such as a nail is driven toward the base plate 20 so as to penetrate the nail hole 40. Further, in a strong wind area, a reinforcing screw 45 is driven into the eaves side of the upper flat roofing material 1 so as to penetrate the lower flat roofing material 1 so that the strong wind blows. The flat roof material 1 is prevented from turning up.

  Various methods other than the above have been studied. For example, a clip is fixed to the surface of the flat roof material 1 with a nail or the like, and another flat roof material 1 is placed so as to be hooked on the clip. This is also disclosed (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 5-40438

  However, when it is constructed by the method as shown in FIG. 6, it is necessary to form a hole for driving the reinforcing screw 45 with a concrete drill or the like at the construction site. There was also a risk of damage such as cracks and cracks. In addition, after forming a hole for driving the reinforcing screw 45, a waterproofing material 5 such as a waterproof sheet is placed between the upper flat roofing material 1 and the lower flat roofing material 1 in order to increase water blocking. There was also a problem that it took much time for the construction.

  Further, even when a clip is provided on the surface of the flat roof material 1 as in Patent Document 1, the flat roof material 1 is damaged when the clip is fixed with a nail or the like, and the number of constituent members also increases. There was also a problem.

  The present invention has been made in view of the above points, and it is possible to eliminate the trouble of forming nail holes and the like at the time of laying, and to prevent the flat roof material from being damaged, and to provide a flat roof material excellent in workability and stability. It is intended to provide.

  The flat roof material according to the present invention is a flat roof material stacked and rolled in the inclination direction of the roof, wherein the flat roof material has an exposed portion and a non-exposed portion, and among the flat roof materials adjacent in the inclined direction. The flat roof material is constructed so that the exposed portion of the flat roof material located on the upper side in the inclined direction is overlaid on the non-exposed portion of the flat roof material located on the lower side in the inclined direction, A plurality of fixing holes into which the fixing tool can be inserted are formed in the non-exposed part, and at least one reinforcing hole into which the fixing tool can be input is formed in the exposed part. Sometimes the reinforcing hole of the flat roof material located on the upper side in the inclined direction and at least one of the fixing holes of the flat roof material located on the lower side in the inclined direction are positioned so as to overlap each other. Reinforcing holes are provided. To.

  Moreover, it is preferable that the said flat roof material is formed so that the area of the said fixing hole which overlaps the lower side of the said hole for reinforcement when it laps and constructs is larger than the area of the said hole for reinforcement.

  Moreover, it is preferable that the said flat roof material is provided with the water stop material in the fixing hole which overlaps the lower side of the said hole for reinforcement when carrying out lap construction so that the opening may be obstruct | occluded.

  The flat roof material of the present invention saves labor for forming nail holes and the like at the time of laying, and can prevent the flat roof material from being damaged, and is excellent in workability and stability.

An example of embodiment of the flat roof material of this invention is shown, (a) is the top view, (b) is a top view which shows the construction state. An example of other embodiment of the flat roof material of the present invention is shown, (a) is the top view, and (b) is the top view of the construction state. It is a top view of the construction state which shows an example of other embodiment same as the above. It is side surface sectional drawing which shows an example of other embodiment same as the above. An example of other embodiment same as the above is shown, (a) is a side view sectional view showing the construction state, (b) is a schematic view of a cap member. The construction state of the flat roof material of a prior art example is shown, (a) is the top view, (b) is the side view sectional drawing.

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

  As shown in FIG. 1 (a), the flat roof material 1 of the present invention is formed into a wide flat plate shape in a substantially rectangular shape in plan view, and the upper piece of the flat roof material 1 is a ridge side end 1a. The lower piece is formed as an eaves side end 1b. In addition, the shape of the flat roof material 1 is not limited to a substantially rectangular shape in plan view, but may be other shapes.

  And the flat roof material 1 is piled up along the inclination direction of the roof 30. As shown in FIG. Specifically, as shown in FIG. 1 (b), the roof is piled up and constructed while adjoining vertically from the eave side, which is the lower side of the tilt direction, toward the ridge side, which is the upper side of the tilt direction. 30 is formed. In this case, in the flat roof material 1, the ridge-side end 1a is positioned on the upper side (ridge side) in the tilt direction, and the eaves-side end 1b is positioned on the lower side (eave side) in the tilt direction. In addition, although the flat roof material 1 is usually overlaid on the surface of the field board 20 grade | etc., It is abbreviate | omitting in the figure. Moreover, in the direction (left-right direction of the flat roof material 1) orthogonal to an inclination direction, it lays down so that the side end surfaces of the flat roof material 1 may face | match.

  Further, the flat roof material 1 has an exposed part 6 and a non-exposed part 7. The exposed portion 6 is a portion exposed to the outside when the flat roof material 1 is overlaid, and the non-exposed portion 7 is overlapped and positioned on the lower side when the flat roof material 1 is overlaid. However, it is a portion that is not exposed to the outside. In the flat roof material 1, the exposed portion 6 is located below (eave side) than the non-exposed portion 7.

  When attention is paid to the flat roof materials 1 and 1 adjacent to each other in the inclination direction of the roof 30 (hereinafter sometimes referred to as the eaves direction), in this case, the unexposed portion 7 of the flat roof material 1 arranged on the eaves side The flat roof material 1 arrange | positioned at the ridge side is piled up. And the exposed part 6 of the flat roof material 1 arrange | positioned at the ridge side is located above the non-exposed part 7 of the flat roof material 1 arrange | positioned at the eaves side.

  A plurality of fixing holes 4 are formed in the non-exposed portion 7 of the flat roof material 1 as shown in FIG. 1A, and at least one of the fixing holes 4 includes the flat roof material 1. The fixing tool 3 for fixing the base plate 20 to the base plate 20 or the like can be driven. In addition, at least one or more reinforcing holes 10 are formed in the exposed portion 6 of the flat roof material 1 and are piled up by driving the fixture 3 into the reinforcing holes 10 as will be described later. In order to firmly connect the flat roof materials 1 adjacent to each other in the vertical direction, they are formed. For example, a nail, a screw, a screw, a through bolt, or the like can be used as the fixture 3.

  Hereinafter, the formation positions of the fixing hole 4 and the reinforcing hole 10 will be described. First, the plurality of fixing holes 4 of the flat roof material 1 arranged on the eaves side (downward) among the flat roof materials 1 and 1 adjacent in the eaves ridge direction when the flat roof material 1 is rolled over. It is preferably formed so as to be located slightly on the ridge side from the ridge side end 1a. On the other hand, the reinforcing hole 10 is positioned so as to overlap with the fixing hole 4 of the flat roof material 1 disposed on the eave side (downward) of the flat roof materials 1 and 1 adjacent in the eave building direction. It is formed in such a place.

  Then, when connecting and fixing the flat roofing material 1 to the base plate 20 in a stacked manner, the fixing tool 3 is driven into the fixing hole 4 of the flat roofing material 1 arranged on the ridge side, and the fixing hole is inserted. 4 is passed through and inserted into the base plate 20. As described above, the fixing hole 4 is formed so as to be positioned slightly on the ridge side than the ridge side end portion 1a of the flat roof material 1 disposed on the eave side. The fixture 3 can be easily inserted without penetrating the flat roof material 1. Of the plurality of fixing holes 4, the fixing tool 3 may be inserted into any of the fixing holes 4. For example, when the fixing holes 4 are formed at four locations in the left-right direction as shown in FIG. 1. As shown in the figure, the flat roofing material 1 can be stably connected to the base plate 20 if the fixtures 3 are driven into two places at both ends.

  On the other hand, the reinforcing hole 10 of the flat roof material 1 arranged on the ridge side is positioned so as to overlap the fixing hole 4 of the flat roof material 1 arranged on the eave side in the vertical direction as described above. ing. Therefore, when the fixing tool 3 is driven into the reinforcing hole 10, the fixing tool 3 is also driven through the fixing hole 4 of the lower flat roof material 1 and then inserted into the base plate 20. Therefore, the flat roof materials 1 and 1 adjacent in the eaves-ridge direction are firmly connected to each other, and the flat roof material 1 is stably connected to the field board 20. Thus, since the flat roof material 1 is stably piled up, even if a strong wind blows, it becomes easy to prevent the flat roof material 1 from turning up.

  As described above, in the flat roof material 1 according to the present invention, the reinforcing holes 10 are formed in the flat roof material 1 in advance, and therefore, when the flat roof material 1 is overlaid and constructed, drilling is performed with a concrete drill. This saves time and effort, and can prevent the flat roof material 1 from cracking. Further, since the reinforcing hole 10 is provided at a position where it overlaps with the fixing hole 4 when the flat roof material 1 is rolled up, the reinforcing hole 10 is reinforced when the fixing tool 3 is driven into the reinforcing hole 10. It penetrates the service hole 10 and further penetrates the fixing hole 4 below. Therefore, the fixing tool 3 can be easily driven into the reinforcing hole 10. That is, even if the fixing tool 3 is driven into the reinforcing hole 10, no new hole is formed in the flat roof material 1 on the lower side, so that the flat roof material 1 is inserted when the fixing tool 3 is driven. Cracks and the like are less likely to occur.

  Since the reinforcing hole 10 is provided at a position overlapping the fixing hole 4 in the vertical direction as described above, the single fixing tool 3 is used to strike both the upper and lower reinforcing holes 10 and the fixing hole 4. It is possible to reduce the total number of the fixtures 3 to be inserted into the flat roofing material 1. Specifically, in the example of FIG. 6, a total of six fixing tools 3 are provided, but in the embodiment of FIG. 1, two fixing tools 3 are provided in the fixing holes 4 and 2 in the reinforcing holes 10. With a total of four books, construction stability equal to or higher than that can be maintained.

  Therefore, in the flat roof material 1 of the present invention, it is possible to save the trouble of forming nail holes and the like at the time of laying, and to reduce the number of fixtures 3 used. It is difficult and has excellent workability and stability.

  The number of reinforcing holes 10 and fixing holes 4 is not limited to that of the embodiment shown in FIG. 1, but 1 to 5 reinforcing holes 10 and 2 to 6 fixing holes 4 are used. It is preferable to provide in the range of this, and if it is this range, it can avoid impairing the construction property and stability of the multi-layered roofing material 1. In the case where a plurality of fixing holes 4 and reinforcing holes 10 are formed, it is preferably formed on the same straight line in the horizontal direction of the flat roof material 1. It can be made more stable.

  Further, the reinforcing hole 10 and the fixing hole 4 may be penetrated or may be semi-through.

  Moreover, in the said embodiment, it has mounted so that it may shift | deviate laterally only the length of 1/2 of the width dimension of the flat roof material 1 with respect to the flat roof material 1 located in the eaves side (lower side). However, it is not limited to such construction. That is, in the case of the flat roof material 1 in which the fixing holes 3 and the reinforcing holes 10 are formed as shown in FIG. 1, the mounting holes 3 and the reinforcing holes 10 are shifted laterally by a length of 1/3 of the width of the flat roof material 1. It may be placed. Also in this case, the reinforcing hole 10 of the flat roof material 1 located on the ridge side (upper side) is positioned so as to overlap the fixing hole 4 of the flat roof material 1 arranged on the eave side in the vertical direction. It will be a thing.

  As shown in FIG. 2, the fixing hole 4 may have an opening area larger than the opening area of the reinforcing hole 10. That is, when the openings of the fixing hole 4 and the reinforcing hole 10 are circular, the diameter of the fixing hole 4 may be formed larger than the diameter of the reinforcing hole 10. In particular, when the flat roof material 1 is overlaid, it is preferable that the fixing hole 4 at a position overlapping below the reinforcing hole 10 be larger than the opening area of the reinforcing hole 10.

  As described above, by making the opening area of the fixing hole 4 larger than the reinforcing hole 10, when the flat roof material 1 is overlaid and constructed, the flat roof materials 1, 1 adjacent in the eaves-ridge direction are somewhat Even if they are overlapped in a shifted state, the fixture 3 can be easily driven into the reinforcing hole 10. That is, even if the positions of the two are slightly deviated, a part of the reinforcing hole 10 and the fixing hole 4 can overlap each other in the vertical direction. The positions of 1 and 1 are naturally adjusted. Therefore, when the flat roof material 1 is overlaid, the necessity for disposing it at a strictly accurate position is reduced, so that the construction becomes easier and the construction time can be shortened.

  As shown in FIG. 3, a water-stopping material 5 such as a waterproof sheet may be provided in the fixing hole 4, and the opening of the fixing hole 4 may be closed to increase the water-stopping property of the fixing hole 4. In particular, the water blocking material 5 is preferably provided on the upper surface of the fixing hole 4 at a position overlapping the lower part of the reinforcing hole 10 when the flat roof material 1 is rolled up. When the water blocking material 5 is provided in this way, the water blocking material 5 is penetrated by the fixing tool 3 when the fixing tool 3 is driven into the reinforcing hole 10. By providing the waterproof material 5 on the flat roof material 1 in this way, it is easy to prevent water from entering the gap between the fixing hole 4 and the fixture 3 and prevent water from reaching the base plate 20. Become.

  In the case of the flat roof material 1 of this embodiment, since the reinforcing hole 10 has already been formed, the water blocking material 5 can be provided in the fixing hole 4 in advance before the flat roof material 1 is overlaid. It will be a thing. In the conventional flat roofing material 1, the reinforcing hole 10 is sometimes formed after being rolled over, so that the water blocking material 5 is inserted between the upper flat roofing material 1 and the lower flat roofing material 1. Although there was a trouble and it was difficult to provide the water stop material 5, in this embodiment, such a trouble can be omitted.

  As the water blocking material 5, in addition to the waterproof sheet as described above, as shown in FIG. 4, it may be embedded in the fixing hole 4 to close the fixing hole 4. good. As the material of the water stop material 5 in this case, for example, butyl rubber, EPDM (ethylene / propylene / diene rubber), silicon or the like can be used. In this case, as in the case of using a waterproof sheet or the like, the flat roof material 1 can be provided in advance before being overlaid on the fixing holes 4.

  When carrying out laying construction in a light wind region or the like, for example, as shown in FIG. 5, a cap member 25 can be provided in the reinforcing hole 10 instead of providing the fixture 3. This is because, in a low wind area or the like, the fixture 3 only in the fixing hole 4 of the flat roof material 1 on the ridge side (upper side) of the flat roof materials 1 and 1 adjacent to each other in the eaves ridge direction when stacked. This is because it may be possible to install the flat roof material 1 with sufficient stability simply by driving in.

  As shown in FIG. 5B, the cap member 25 is embedded in the reinforcing hole 10 and a head portion 25 a that is partially exposed on the upper surface of the reinforcing hole 10 when mounted in the reinforcing hole 10. And the stopper portion 25b. The head 25a is made of, for example, a material such as stainless steel, iron, or other noncombustible material. On the other hand, the plug portion 25b is made of a material such as butyl rubber, EPDM (ethylene / propylene / diene rubber), silicon, and the like, and can improve the water blocking property of the reinforcing hole 10. The tip of the plug portion 25b is preferably formed in a rounded shape such as a substantially arc-shaped cross section so that it can be easily inserted into the reinforcing hole 10. Note that the head portion 25a and the plug portion 25b may be formed integrally with each other, or may be such that both are detachably connected.

  And, in the case of laying construction in a light wind area or the like, it is performed as follows. First, similarly to the above, the flat roof material 1 is piled up in the eaves-ridge direction, and the fixture 3 is driven only into the fixing holes 4 to fix the flat roof material 1 to the field board 20. On the other hand, instead of driving the fixing tool 3 into the reinforcing hole 10, as shown in FIG. 5 (a), the cap member 25 is placed with the head portion 25a on the upper side and the plug portion 25b on the lower side. Insert it. Note that the cap member 25 can be provided in the reinforcing hole 10 in advance before the flat roofing material 1 is overlaid.

  As described above, in the flat roof material 1 according to the present invention, when it is laid in a low wind area or the like, it is only necessary to drive the fixing tool 3 into the fixing hole 4. Since a dedicated cap member 25 is provided instead of driving the fixing tool 3, it is possible to prevent water from entering the reinforcing hole 10. Moreover, the cap member 25 for exclusive use can also be used for the hole 10 for a reinforcement as a member for a decoration, and it also becomes possible to improve the design property of the roof 30 formed by overlapping and rolling the flat roof material 1. .
