Description

  The present invention relates to a flat roof tile to be constructed by driving nails.

  Tile used as a roofing material for a house is a major player in the appearance design of the roof, and has functions such as reducing rain noise and enhancing the waterproofness of the roof.

  Conventionally, the flat tile 10 as shown in FIG. 5 is proposed as one of the roofing materials (refer patent document 1). Even if this flat roof tile 10 is one kind, it is possible to store the eaves. For example, a tile called a so-called starter arranged at the eaves of the roof can be obtained by dividing the flat roof tile 10 into two equal parts along the vertical center imaginary line S1 passing through the center in the vertical direction. it can. And the flat roof tile 10 can be arrange | positioned as a 1st-stage roof tile on the starter obtained in this way. From the second stage onward, the flat roof tile 10 can be rolled up to the ridge side and tiled. For this reason, the flat roof tile 10 facilitates the accumulation of roof tiles and is effective in reducing building waste. Such a flat roof tile 10 has a horizontally long rectangular shape as a basic shape in plan view so that it has the same shape even if it is turned upside down.

  In the flat roof tile 10 as described above, the flat roof tile 10 provided with no nail holes as shown in FIG. 5 or the flat roof tile provided with half-penetrated nail holes 11 as shown in FIG. 10 exists. The reason why the nail hole 11 is made to be half-penetrated is that if the nail hole 11 is made to penetrate, water may enter, the strength may be reduced, and the design may be deteriorated. is there.

  However, in the flat roof tile 10 having no nail holes shown in FIG. 5, it is necessary to confirm and determine the nail driving position P at the site during construction. When the nail driving position P is determined on site, it is complicated to determine the nail driving position P, and the nail driving position P is difficult to be determined. For example, in order to determine an appropriate nail driving position P, it is necessary to measure using a ruler, and it is necessary to write auxiliary lines 12 in the vertical direction and the horizontal direction according to the measurement. If the nail driving position P is determined while measuring with such a ruler, it takes time to determine an appropriate position of the nail driving position P. In addition, there is a risk that a nail hole or a nail is drilled at a position where a hole should not be formed, causing a leak of rain.

  On the other hand, the flat roof tile 10 provided with the semi-penetrating nail hole 11 in FIG. 6A can easily recognize the nail driving position P and has excellent workability. However, in the flat roof tile 10 provided with the semi-penetrating nail hole 11, the semi-penetrating nail hole 11 in which the nail is not driven may remain after the construction. In some parts, dirt is conspicuous over time, which may impair the design. Further, in the flat tile 10 provided with the half-penetrated nail hole 11, when the hole is penetrated by the roof nail, there is a possibility that Hanasaki X (a tear extending from the nail hole 11) may occur, and the flat tile 10 may be damaged. is there. For example, FIG. 6B shows a state of the flat roof tile 10 in which nails are driven from the front surface and flower bloom X is generated on the back surface. When Hanasaki X occurs on the back side, Hanasaki X cannot be confirmed from the front surface, and there is a possibility that the roof is constructed with the flat roof tiles 10 that are damaged, which may reduce the strength of the roof.

  The present invention has been made in view of the above circumstances, and it is possible to easily determine an appropriate nail driving position without impairing the design property or weakening the strength, and to provide a flat roof tile with good workability. The purpose is to provide.

The flat roof tile according to the present invention has a horizontally long rectangular shape in plan view, and vertical marks for determining the vertical position of the nailing position are provided on both horizontal end portions from the edge of the vertical end portion. The horizontal mark for determining the horizontal position of the nail driving position is provided at both vertical ends , and a virtual line connecting the vertical marks arranged in the horizontal direction is provided on the nail. It becomes a vertical position virtual line for determining the vertical position of the hitting position, and a virtual line connecting horizontal marks arranged in the vertical direction becomes a horizontal position virtual line for determining the horizontal position of the nailing position, and the vertical position virtual line And the horizontal position imaginary line is the nail driving position, and there is no nail hole .

  In a preferred form of the flat roof tile, the vertical mark and the horizontal mark are formed symmetrically with respect to a vertical center imaginary line passing through the center in the vertical direction. Moreover, with a preferable form, it can divide | segment along the said vertical center virtual line. In a preferred embodiment, the horizontal mark has a notch shape. In a preferred embodiment, the vertical mark is formed by protrusions.

  According to the present invention, an appropriate nail driving position can be easily determined, and a flat roof tile with good workability can be obtained.

  FIG. 2 is a plan view showing an example of the embodiment of the flat roof tile 1 according to the present invention. FIG. 1 is a plan view illustrating an embodiment of the flat roof tile 1, and various imaginary lines are entered in the embodiment of FIG.

  The flat roof tile 1 is formed with a horizontally long rectangle as a basic shape in a plan view. Vertical marks 4 for determining the vertical position (vertical position) of the nailing position P are provided at both horizontal end portions 2 (both end portions in the horizontal direction) of the flat roof tile 1. Horizontal marks 5 for determining the horizontal position (lateral position) of the nail driving position P are provided at both vertical end portions 3 (both ends in the vertical direction) of the flat roof tile 1.

  The flat roof tile 1 in FIG. 2 is formed as a flat roof tile 1 that can store the eaves even if it is one kind. As shown in FIG. 1, the flat roof tile 1 can be divided into two equal parts along a vertical center virtual line S <b> 1 extending in the horizontal direction through the center in the vertical direction. Thus, by dividing the flat roof tile 1 vertically, two roof tiles having the same shape can be obtained. The divided tiles can be tiles called commonly called starters arranged at the eaves of the roof. That is, the flat roof tile 1 is formed in the same shape even if it is turned upside down. For this reason, the flat roof tile 1 makes it easy to accumulate tiles and is effective in reducing building waste.

  In the form of FIG. 2, as shown in FIG. 1, the flat roof tile 1 can be divided into two equal parts along a horizontal center virtual line S <b> 2 extending in the vertical direction through the center in the horizontal direction. The horizontally divided tile can be used as a half tile with a half length in the horizontal direction, and in particular, it can be used as a half tile laid at the end in the direction perpendicular to the eaves direction of the roof. .

  The size of the flat roof tile 1 is not particularly limited. For example, a rectangle having a short side (vertical side) of about 300 to 450 mm and a long side (horizontal side) of about 450 to 1000 mm is defined as a basic shape. The flat roof tile 1 can be made.

  In said form, the convex part 6 which protruded in the horizontal direction is formed in both the side edge parts 2 of the flat roof tile 1. As shown in FIG. The protruding portion 6 is formed in a rectangular shape or a trapezoidal shape in plan view. The protruding portion 6 is formed so as to straddle the vertical center virtual line S1, and the width in the vertical direction is wider than the protruding length. The projecting portions 6 and 6 at both lateral ends 2 are formed in the same shape. In addition, although the convex part 6 may be provided only in any one horizontal end part 2, it is preferable that it is provided in both the horizontal end parts 2. FIG. In that case, roof tiles having the same shape can be obtained when divided.

  The protruding length of the protruding portion 6 is not particularly limited. For example, the protruding length can be 1 mm or more from the viewpoint of mark properties, and the protruding length is 5 mm or less from the viewpoint of design. Can be.

  The vertical mark 4 is formed by projecting the projecting portion 6. In the above embodiment, the vertical mark 4 is formed as an edge (root portion or tip edge) of the projecting portion 6. That is, the vertical mark 4 is the rising position of the protrusion from the lateral end 2 to the protrusion 6 or the position of the tip edge of the protrusion 6. And the four places of the edge part of the convex part 6 provided in both the horizontal ends 2 are provided as the vertical mark 4. FIG. Note that the vertical mark 4 is not limited to the root portion or the tip edge portion of the projecting portion 6, and may be formed in a notch shape or a protrusion shape as in the later-described horizontal mark 5 (see FIG. 3). ). In addition to the vertical mark 4 near the center in the vertical direction, another vertical mark 4 may be provided at a position between the protruding portion 6 and the vertical end portion 3. In that case, it becomes possible to drive a nail into a position close to the vertical end 3.

  The vertical mark 4 is provided at a position separated from the edge of the vertical end portion 3 by at least the total length of the scooping leg length L1 and the minimum overlap allowance L2. In the above embodiment, the vertical marks 4 are formed at vertical positions (two places) that are separated from the edges of the vertical end portions 3 on both sides by the distance or more.

  As shown in the construction state of FIG. 4, the length L1 is the length in the eaves ridge direction of the region where the flat tile 1 is exposed as the roof surface when construction is performed. Further, the minimum stacking allowance L2 is the minimum from the end (vertical end 3) on the eaves side of the flat roof tile 1 stacked on the upper side when construction is performed to the nailing position P of the flat roof tile 1 stacked on the lower side. Distance (length in the eaves building direction). Here, the stacking allowance is the lower flat roof tile 1 covered by the flat roof tile 1 from the position of the eaves side end (vertical end 3) of the upper flat roof tile 1 necessary for water ending. It is the length in the direction of the eaves to the nailing position P. By setting the length of the overlap allowance longer than the minimum overlap allowance L2, that is, by setting the nail driving position P to be equal to or greater than the minimum overlap allowance L2 from the eave side end portion of the upper flat roof tile 1 A gap (nail hole) formed in the slender portion can be positioned on the inner side of the upper flat roof tile 1, and a good roof such as waterproofness can be formed.

  For example, the length of the leg length L1 can be 90 to 230 mm, but is not limited thereto. The length of the minimum overlap allowance L2 can be, for example, 50 mm or more (upper limit 80 mm), but is not limited thereto.

  In the form of FIG. 1, a plurality of (two in FIG. 1) vertical marks 4 provided on one horizontal end 2 are provided at positions symmetrical with respect to the vertical central virtual line S1. Further, in one horizontal end 2 and the other horizontal end 2, the vertical marks 4, 4 arranged in the horizontal direction have the same vertical position and are provided at positions symmetrical with respect to the horizontal central virtual line S 2. Yes. A virtual line connecting the two vertical marks 4 and 4 arranged in the horizontal direction becomes a vertical position virtual line T1 for determining the vertical position of the nail driving position P. The vertical position virtual line T1 is a straight line extending in the horizontal direction, and is a straight line parallel to the horizontal side of the rectangle in the basic shape of the flat roof tile 1 or the horizontal central virtual line S1.

  Further, a plurality of horizontal marks 5 (five in each case in FIG. 1) are provided at each vertical end 3. Among the plurality of horizontal marks 5 provided at one vertical end 3, the ones other than the horizontal mark 5 arranged at the center in the horizontal direction are provided at positions symmetrical with respect to the horizontal central virtual line S2. . Further, in one vertical end 3 and the other vertical end 3, the horizontal marks 5, 5 arranged in the vertical direction have the same horizontal position and are provided at positions symmetrical with respect to the horizontal central virtual line S <b> 1. Yes. A virtual line connecting the two horizontal marks 5 and 5 arranged in the vertical direction becomes a horizontal position virtual line T2 for determining the horizontal position of the nail driving position P. The horizontal position virtual line T2 is a straight line extending in the vertical direction, and is a straight line parallel to the rectangular vertical side in the basic shape of the flat roof tile 1 or the horizontal central virtual line S2.

  Thus, it is preferable that the vertical mark 4 and the horizontal mark 5 are formed in line symmetry with respect to two vertical and horizontal central virtual lines. Thereby, when divided | segmented, the same-shaped roof tile can be obtained.

  In the flat roof tile 1 of the said form, the horizontal mark 5 is formed in the notch shape. The horizontal mark 5 and the vertical mark 4 are triangular cutouts (triangular notches) as shown in FIG. 3 (a), or semicircular cutouts (round notches) as shown in FIG. 3 (b). Or a square or trapezoidal notch (square notch) as shown in FIG. Further, the horizontal mark 5 may be formed in a convex shape (or a protruding shape). In short, the horizontal mark 5 and the vertical mark 4 are not particularly limited as long as they become marks that serve as indexes of the nail driving position P. However, it is preferable that the vertical mark 4 is formed by protruding from the viewpoint of waterproofness. Moreover, it is preferable that the horizontal mark 5 is notched from a design viewpoint.

  In the central portion in the horizontal direction of the vertical end portion 3, the horizontal mark 5 provided on the vertical central imaginary line S2 is formed as a concave projection 7 in which a projection is formed from the deep portion of the concave cutout portion. ing. By forming the horizontal mark 5 in the central portion in the horizontal direction on the concave protrusion 7, the central position in the horizontal direction can be easily determined and the workability of the flat roof tile 1 can be improved.

  The size of the cutout of the horizontal mark 5 is not particularly limited. For example, the cut depth can be 1 mm or more from the viewpoint of mark properties, and the cut depth is 5 mm from the viewpoint of design. It can be:

  The vertical marks 4 and the horizontal marks 5 can be formed by printing or the like, but in order to easily determine an appropriate nail driving position P, the shape of the flat roof tile 1 may be changed. preferable. Further, the vertical mark 4 and the horizontal mark 5 may be provided on the surface of the flat roof tile 1 as a stamp or the like with a part of the surface being concavely or convexly formed. 2 and the edge of the vertical end 3 are preferably formed. By forming the mark on the edge, the nail driving position P can be specified more easily. Further, since the dirt is not easily accumulated at the edge, the mark can be made inconspicuous.

  The vertical mark 4 and the horizontal mark 5 may be provided at the time of molding the material constituting the flat roof tile 1, or may be provided by performing notch processing after molding.

  In the flat roof tile 1, the intersection of the vertical position virtual line T1 and the horizontal position virtual line T2 becomes the nail driving position P. However, it is not necessary to nail all the intersections, and only the intersections necessary for the construction of the flat roof tile 1 can be set as the nail driving positions P. For example, a nail can be driven only into the vertical half region of the flat roof tile 1. Specifically, in the form of FIG. 1, the nail is not driven into the nail driving position P ′ at the intersection in the lower half of the intersections between the vertical virtual line T1 and the horizontal virtual line T2. be able to.

  Next, an example of a method for forming the roof by constructing the flat tile 1 according to the present invention will be described.

  FIG. 4 is a schematic plan view showing a construction state of the flat roof tile 1 shown in FIGS. 1 and 2. The flat roof tile 1 is fixed by nailing to the roof surface when roofing tiles. The flat roof tile 1 is usually attached with the vertical direction being the eaves-ridge direction.

  Nailing may be performed by providing a penetrating or semi-penetrating nail hole at the nail position P on the surface of the flat roof tile 1 and then driving the nail into the nail hole. A nail may be driven from the surface of 1 into the nail driving position P. Further, the nailing position P may be marked (marked) with a pen or the like so that the position can be easily understood. Alternatively, the auxiliary line 12 (see FIG. 5) may be entered with a pen or the like at a necessary place (near the nailing position P). In the case of the flat roof tile 1 described above, the auxiliary line 12 and the marking can be simply entered by simply drawing a line at a necessary position in accordance with the position of the mark arranged in the vertical direction or the horizontal direction without measuring with a ruler. be able to. Alternatively, the nails may be driven manually, or they may be driven using a dedicated tool (nailing machine). If you use a special tool, you can easily drive nails with a strong force.

  And when nailing, it is possible to nail only at the necessary nailing position P. In the construction example of FIG. 4, among the intersection points of the horizontal position virtual line T1 and the vertical position virtual line T2, the intersection point of the region overlapped with the flat roof tile 1 disposed on the upper side is adopted as the nail driving position P and nail driving is performed. ing. That is, the flat roof tile 1 is not nailed at the intersection (nail driving position P ′ in FIG. 1) arranged on the eaves side among the intersections of the horizontal position imaginary line T1 and the vertical position imaginary line T2. Are nailed and fixed at the intersection point (nailing position P). Of course, the nail driving position can be the eaves side nail driving position P ', but since a gap is easily formed around the nail by the nail driving, it is arranged on the ridge side in consideration of intrusion of rainwater. It is preferable to nail at the nail driving position P.

  Then, the other flat roof tile 1 is attached to the side edge of the mounted flat roof tile 1 next to each other. Here, the flat roof tiles 1 and 1 which are adjacent in the horizontal direction are disposed with the protruding portions 6 and 6 facing each other. And the gap | interval 8 for the protrusion length of the two convex parts 6 is formed between the adjacent flat tiles 1 and 1 by being attached by the convex parts 6 and 6. FIG. By forming the gap 8 in this way, it is possible to suppress the water from rising and entering due to the capillary phenomenon between the abutting portions of the flat roof tiles 1 and 1, and that the water has increased at the abutting portion. In addition, it becomes possible to drain water in the gap 8, and the waterproofness of the roof can be improved.

  In this way, by attaching a plurality of flat roof tiles 1 in the lateral direction, the flat roof tiles 1 are attached as one step in a direction perpendicular to the eaves-ridge direction.

  Next, the next-stage flat roof tile 1 is mounted on the already-mounted (previous) flat roof tile 1. Nailing can be performed in the same manner as described above. At this time, by covering the nail head of the nail into which the previous flat roof tile 1 is driven and attaching the flat roof tile 1, the gap (nail hole) of the nail can be covered and closed by the upper flat roof tile 1. Thereby, waterproofness improves and a nail hides and design nature improves.

  Moreover, it is also preferable to dispose the flat roof tiles 1 of each step in a staggered manner by shifting the flat roof tiles 1 of adjacent steps substantially in the horizontal direction as in the form of FIG. If it does in this way, a step-like change will be attached to the roof surface, and design nature will improve. In this case, a half roof tile obtained by vertically dividing the flat roof tile 1 may be disposed at an end portion in a direction perpendicular to the eaves-ridge direction.

  And the roof can be formed by attaching the flat roof tile 1 of each step to the roof surface from the eave side to the ridge side, such as the next step, the next step, and so on.

  In the flat roof tile 1 as described above, since the nail driving position P can be determined by the vertical mark 4 and the horizontal mark 5, the appropriate nail driving position P can be easily specified. And since the nailing position P can be specified easily, nailing becomes easy and the workability of the flat roof tile 1 can be improved. Further, since the nail driving position P can be easily identified, a hole is not opened by mistake in the position where the nail is driven, and the risk of rain leakage due to drilling can be reduced. In addition, since the nail hole 11 is not provided, even if the nail is nailed using a dedicated tool, the area around the nail hole is less likely to be damaged, and the occurrence of Hanasaki X (see FIG. 6B) can be suppressed. .
