Description

  The present invention relates to a sleeve tile erected on a sleeve portion of a sloped roof, which can prevent raindrops from falling from the side surface of the sleeve tile during rain and can reliably lead to the eaves. .

Conventionally, as a sleeve tile erected on the sleeve part of a gable roof, etc., it consists of an upper piece part that covers the upper surface of the roofing material, and a hanging part that hangs downward on the wife side of this upper piece part In addition, a structure in which a vertical cross section is formed in an inverted L shape is known (see, for example, Patent Document 1).
However, the sleeve tile described in Patent Document 1 has a phenomenon that raindrops fall off from the joints on the side of the sleeve tile when it rains, which causes noise in a quiet residential area, It was pointed out that it was blown away and could cause roofing materials and surrounding building materials to corrode.

  Therefore, as shown in Patent Document 2 and Patent Document 3, a rain receiving portion having a convex or concave shape extending from the bottom to the head is provided below the hanging portion of the sleeve tile, and the rain receiving portion is continued to the eaves. Have been proposed. According to this, it is possible to prevent rain dripping at the joint portion of the hanging portion by the receiving portion, and it is possible to guide raindrops to the eaves along the rain receiving portion.

  However, in the case of the sleeve tiles shown in Patent Document 2 and Patent Document 3, there is a problem in that the appearance quality deteriorates because a concave or convex pattern crossing in the horizontal direction is provided below the hanging part. Further, in the case of a convex rain receiving portion, there is a problem that productivity is deteriorated due to the necessity of considering a draft, and a problem such as cracking or chipping is likely to occur during use.

  The present invention solves the above-mentioned problems and is a sleeve tile installed on a sleeve portion of a sloped roof, and prevents raindrops from falling from the side of the sleeve tile when it rains, thus ensuring the eaves. The present invention has been completed for the purpose of providing a sleeve tile that can be guided to the above, has a clean appearance with no irregularities, is excellent in design, and can also exhibit excellent productivity.

The sleeve tile of the present invention made to solve the above-mentioned problems is provided with an upper piece part covering the upper surface of the roofing material, and a tile side of the upper part of the roofing material. a sleeve tile composed of a hanging part that is vertically downwardly at,
A thin part with a reduced thickness is formed at the head side edge of the hanging part, while the thin part of the upper sleeve tile erected one step higher is formed on the bottom edge of the hanging part. A concave portion that can be overlapped is formed so as to be flush with each other, and raindrops hanging along the edge of the thin portion of the upper sleeve tile are prevented from falling as raindrops at the lower end of the concave portion. In the sleeve tile which formed the bowl-shaped water receiving part ,
The head portion side of the hanging portion is cut out by a length equal to the overlapping portion of the sleeve tiles to be laid, and the thin portion having a substantially triangular cross section with a reduced thickness at the head side end edge of the hanging portion On the other hand, a concave portion corresponding to the triangular shape is formed at the bottom edge of the bottom portion of the hanging portion, and a water receiving portion equal to the triangular shape is formed at the lower end of the concave portion. it is characterized in that there.

  The length of the thin portion is equal to the overlapping portion of the sleeve tiles to be installed, and the concave portion is also equal to the overlapping portion, and has a strip shape over the entire length of the lower end of the concave portion. A water receiving portion may be formed, and this is the invention according to claim 2.

In the invention which concerns on Claim 1, it is installed in the sleeve part of the roof with a slope, and a tile main body is hung down toward the downward direction in the upper piece part which covers the upper surface of a roofing material, and the wife side of this upper piece part. In the sleeve tile composed of a hanging part, a thin-walled portion is formed on the head side edge of the hanging part, while the bottom edge of the hanging part is provided one step higher. The upper sleeve tile is formed with a recessed portion that can be overlapped so that the surface of the hanging portion is flush, and the lower end of the recessed portion is suspended along the edge of the thin portion of the upper sleeve tile. The raindrops that hang down along the head side edge of the drooping part are transferred to the water catching part once at the lower end and then one step. As it flows down along the lower edge of the lower part of the lower sleeve tile, raindrops rain on the edge of the lower part as in the past. From falling it can be prevented by a record.
Further, the head side of the drooping portion is cut out by a length equal to the overlapping portion of the sleeve tiles to be installed, and the head side end edge of the drooping portion has a substantially triangular cross section with a reduced thickness. A thin-walled portion is formed. On the other hand, a concave portion corresponding to the triangular shape is formed in the concave portion at the bottom end edge of the hanging portion, and water equal to the triangular shape is formed at the lower end of the concave portion. Since the receiving part is formed, the head side edge of the hanging part is in a position where it enters the bottom part side, and there are few raindrops flowing down, making it difficult for raindrops to occur. Moreover, the shape of a dent part and a water receiving part is a simple triangle shape, and can exhibit the outstanding productivity.

  In the invention according to claim 2, the length of the thin portion is equal to the overlapping portion of the sleeve tiles to be installed, and the concave portion is also equal to the overlapping portion, and the concave portion It is assumed that a band-shaped water receiving part is formed over the entire length of the lower end of the water, so that a sufficient amount of raindrops can be retained even when the area of the water receiving part is large and a large amount of rain falls. It is possible to prevent dripping in case of heavy rain.

It is a perspective view which shows embodiment of this invention. It is a front view of FIG. It is a perspective view which shows the laying state of the sleeve tile of FIG. FIG. 4 is a front view of FIG. 3. It is a front view which shows other embodiment. FIG. 6 is a front view of FIG. 5. It is a perspective view which shows the laying state of the sleeve tile of FIG. FIG. 8 is a front view of FIG. 7.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an example of a sleeve tile according to the present invention, and FIG. 2 is a front view. FIG. 3 is a perspective view showing a laying state of the sleeve tile of FIG. 1, and FIG. 4 is a front view.
The sleeve tile according to the present invention is installed on a sleeve portion of a roof having a slope such as a gable roof. In the figure, reference numeral 1 denotes a tile main body 1. Basically, an upper piece 2 covering the upper surface of a roofing material (not shown) such as a field board or a tile, and a lower side on the wife side of the upper piece 2 The cross section perpendicular to the longitudinal direction has a substantially inverted L shape.

  As shown in FIGS. 1 to 4, a thin portion 4 having a reduced thickness is formed at the edge of the drooping portion 3 on the head (T) side. On the other hand, a recess 5 is formed on the bottom edge (S) side edge of the drooping portion 3 so that the thin-walled portion 4 of the upper sleeve roof tiled up one step can be overlapped so that the drooping surface is flush. Further, a bowl-shaped water receiving portion 6 is formed at the lower end of the recessed portion 5 to prevent raindrops hanging along the edge 4a of the thin portion 4 of the upper sleeve tile from falling as raindrops. Has been.

As a result of the study of the flowing state of the water droplets flowing down the hanging portion of the sleeve tile, the present inventor is a phenomenon that occurs when the rain drops from the side of the sleeve tile when it rains. I found out. That is, between the two roof tile joints, water drops flow from the bottom (S) toward the head (T) while maintaining a rounded state due to surface tension at the lower end edge of the hanging part. For this reason, during this time, water drops hardly fall as raindrops.
However, at the joint of the two roof tiles, the water droplets that have flowed down the bottom edge of the droop and the water droplets that have flowed along the side edge of the droop join and grow into large water droplets. It was clarified that the phenomenon of falling by the influence of wind pressure or the like occurs.

Therefore, in the present invention, a recessed portion 5 is formed on the bottom edge (S) side edge of the drooping portion 3 so that the thin-walled portion 4 of the upper sleeve roof tiled up one step can be overlapped, and the lower end of the recessed portion 5 By forming a bowl-shaped water receiving portion 6 that prevents the raindrops hanging along the edge 4a of the thin portion 4 of the upper sleeve tile from falling as raindrops, By holding it once at the water receiving portion 6 and then flowing down along the lower end edge of the lower part of the sleeve tile at the lower stage, it is possible to prevent raindrops from falling down at the edge of the lower part as in the past. I tried to do it.
The bowl-shaped water receiving portion 6 is formed so as not to protrude outward from the surface of the hanging portion 3 and to be flush with the surface of the hanging portion 3. Therefore, in the case of the present invention, since there is no uneven rain receiving portion on the surface of the hanging portion as in the prior art, the surface is smooth and can have a clean appearance, and the productivity is also improved. Can do.

Next, specific shapes of the thin portion 4, the recessed portion 5, and the water receiving portion 6 will be further described.
In the one shown in FIGS. 1 to 4, the length of the thin portion 4 is equal to the length (A) equal to the overlapping portion of the upper sleeve roof tiles provided one step higher. Here, the length of the thin portion 4 refers to the length in the direction from the head (T) of the roof tile body 1 to the bottom (S). On the other hand, the recessed portion 5 is also equal in length to the overlapping length (A), and a band-shaped water receiving portion 6 is formed at the lower end of the recessed portion 5.
Accordingly, the area of the water receiving portion 6 is large and can hold a sufficient amount of raindrops, and even when a large amount of rain falls due to heavy rain, it is ensured that dripping will occur at the joint of the two roof tiles. Can be prevented.

Moreover, in what is shown in FIGS. 5-8, the head side of the said drooping part 3 is notched by the length equivalent to the overlap part of the sleeve tile to be erected, and a plate-like shape is formed in the head (T). The overlapping upper piece 7 is in a protruding state. Further, a thin portion 4 having a substantially triangular cross section with a reduced thickness is formed at the head side edge of the hanging portion 3. On the other hand, a concave portion 5 corresponding to the triangular shape is formed at the bottom edge of the hanging portion 3, and a water receiving portion 6 equal to the triangular shape is formed at the lower end of the concave portion 5.
Therefore, since the head side edge of the drooping portion 3 is located at the bottom side, there are few raindrops flowing down, and raindrops will occur even if it merges with raindrops flowing down the drooping bottom edge. It has a difficult structure. Moreover, the shape of a recessed part and a water receiving part is a simple triangular shape, and can also exhibit the outstanding productivity.

  In addition, about the shape of the said thin part 4, the recessed part 5, and the water receiving part 6, it is not limited to the thing of illustration, Of course, a design change can be arbitrarily carried out according to a use purpose.

As shown in FIG. 3 and FIG. 7, the sleeve tile of the present invention configured as described above overlaps the head (T) of the upper sleeve tile, which is provided one step higher than the bottom portion (S) of the sleeve tile. In this way, they are installed one after another and used. In the present invention, a thin-walled portion with a reduced thickness is formed at the head side edge of the hanging part of the roof tile body, while a concave part capable of superimposing the thin-walled part is formed at the bottom edge of the hanging part. And formed at the lower end of the recess is a bowl-shaped water receiving portion that prevents raindrops hanging along the edge of the thin portion from falling as raindrops. The raindrops that hang down along the edge once move to the water receiving portion at the lower end, and then flow down along the lower end edge of the lower part of the sleeve tile at the lower stage, so that the raindrops hang down at the edge of the droop as in the past. Thus, it is possible to accurately prevent the fall.
In addition, since there is no uneven rain receiving portion on the surface of the hanging portion as in the prior art, the surface is smooth and can have a clean appearance, and the productivity can be improved.
