  However, in the case of providing the roof draining material 1 having the above-described gouge bar 9, the roof bar 9 can be fixed to the roof by using the hanging hook 12. If the roofing material 8 is stepped on at the time of construction, or if there is a problem with fixing by the hanger 12, the shape of the goby return 9 will be crushed, and the waterproof function may not be fully demonstrated. There was sex. Further, there is a risk that the function of draining cannot be performed due to water intruding between the goblet return 9 and the suspension 12. Further, the fitting between the goby return 9 and the suspension 12 requires processing such as raising or cutting off, and requires skill.

  In addition, a plurality of roof drainers 1 having such a goby return 9 are connected to a plurality of drain drains 10 along the wife of the roof in the eaves ridge direction shown in FIG. 9, or a valley drainer 11 shown in FIG. In the case of providing a plurality of connected along the valleys of the roof, it is necessary to install a part of the edges of the adjacent roof drainers 1 in this case. As shown in FIG. 8 (b), the top 9 of the roof draining material 1 is widened and the back 9 of the other roof draining material 1 is narrowed, and then the former back 9 It was necessary to connect the roof draining material 1 so as to insert the latter gouge return 9, and the construction work was troublesome.

  Also, as described in Patent Document 2, when the waterproof dam 3 having a U-shaped cross section, for example, is provided in the flat member 2, the waterproof dam 3 is crushed by stepping on the roof material 8 during construction. There is a possibility that the waterproof function cannot be exhibited. In particular, as shown in FIGS. 11 (a) and 11 (b), the distance between the base end portions 5 and 6 on both sides of the waterproof weir 3 when the roof drainer 1 is laid on the field 7 If the waterproof weir 3 is laid so as to be narrower than the original width, the waterproof weir 3 is extremely weak in resistance to the load from above, and the waterproof weir 3 is likely to be crushed as described above.

  The present invention has been made in view of the above points, and when performing draining by interposing between the field and the roofing material, it is possible to prevent the prevention function from being impaired by stepping during construction. An object of the present invention is to provide a roof drainer that can be easily installed.

  The invention according to claim 1 is a roof drainage material 1 that is interposed between a field 7 and a roofing material 8 and drains water, and a flat material portion 2 disposed between the field 7 and the roofing material 8. The waterproof weir 3 projecting from the edge of the flat member 2 toward the roof member 8 and the base end 6 opposite to the base member 5 on the flat member 2 side of the waterproof weir 3 are extended. In addition, a fixed piece 4 fixed to the field 7 is provided, and the cross-sectional shape in a plane orthogonal to the longitudinal direction of the waterproof weir 3 has a base end 5 on the flat member 2 side and a base end on the fixed piece 4 side. Further, the width dimension in the direction perpendicular to the longitudinal direction of the waterproof weir 3 is formed so as to be narrower toward the roof material 8 side.

  The invention according to claim 2 is characterized in that, in claim 1, the cross-sectional shape of the waterproof weir 3 is a right triangle shape in which the base end portion 5 on the flat material portion 2 side forms a right apex.

  According to the invention which concerns on Claim 1, even if water infiltrates between the roofing material 8 and the field 7 in the location where the roof draining material 1 is installed, this water entry is prevented by the waterproof weir 3 Can do. Moreover, when installing this roof draining material 1, the fixing piece 4 should just be fixed to the field 7 with the appropriate fixing tool 13, and the installation of the roof draining material 1 becomes very easy, The operator does not need a high level of skill. Further, the waterproof weir 3 is highly resistant to the load from above, and the load is applied to the waterproof weir 3 from above by, for example, the operator stepping on the roof material 8 above the waterproof weir 3 in the roof installation work or the like. Even if the waterproof weir 3 is less likely to be crushed, the waterproof action by the waterproof weir 3 can be maintained, and the flat member 2 is pushed in and its arrangement position is shifted to the fixed piece 4 side. When the roof drainage 1 is installed, the fixing position of the fixing piece 4 is shifted to the flat member 2 side, and a situation occurs in which the distance between the base end portions 5 and 6 on both sides of the waterproof weir 3 is reduced. Even so, the cross-sectional shape of the waterproof weir 3 is suppressed from protruding to the outside of the two base end portions 5 and 6, and high durability against the load from above the waterproof weir 3 can be maintained. The waterproof performance can be maintained. Further, when a plurality of roof drainers 1 are connected and installed, only one edge of the other roof drainer 1 is overlapped on the edge of one roof drainer 1, and one waterproof weir 3 The other waterproof weir 3 can be stacked on top of the other, so that it is not necessary to expand or narrow the waterproof weir 3 and the roof drainer 1 can be easily connected.

  According to the second aspect of the present invention, the dimension from the top part to the base end part 5 is shorter on the side surface on the flat member 2 side than the side surface on the fixed piece 4 side of the waterproof weir 3. When a situation occurs in which the distance between the base end portions 5 and 6 on both sides becomes narrow, even if the flat material portion 2 side is lifted upward, the fixed piece 4 is prevented from floating upward. The fixed piece 4 can be prevented from floating from the field 7, and a high mounting strength is imparted to the roof drainer 1 and the waterproof performance by the roof drainer 1 is maintained.

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

  As a first embodiment, FIGS. 1 and 2 show a roof drainage material 1 formed as a drain drainer 10 provided on a loose part of a roof of a building.

  The drainer 10 is formed of a folded plate obtained by bending a single plate made of metal or the like. The drainage 10 is provided with a waterproof weir 3 projecting upward over the entire edge of one end of the flat plate member 2, and the waterproof weir 3 on the flat member 2 side. A fixed piece 4 extends from a base end portion 6 on the side opposite to the base end portion 5. The flat member 2 and the fixed piece 4 are formed flush with each other. Further, a bent piece 24 extends upward from the edge of the flat member 2 opposite to the waterproof weir 3 and the fixed piece 4, and the upper end of the bent piece 24 has an acute angle toward the fixed piece 4. A folded piece 25 is provided.

  The cross-sectional shape of the waterproof weir 3 in the drainage 10 in a plane orthogonal to the longitudinal direction is between the base end 5 on the flat member 2 side and the base end 6 on the fixed piece 4 side. It forms so that it may become a shape, and the width dimension of the direction orthogonal to the longitudinal direction of this waterproof dam 3 is formed so that it may become narrow toward the roof material 8 side. At this time, the side surfaces of the waterproof dam 3 on the flat material portion 2 side and the fixed piece 4 side rise from each base at a rising angle θ of 90 ° or more, and the side surfaces protrude upward without being warped outward. Is formed.

  Such a waterproof weir 3 can be formed in an appropriate shape. For example, a cross-sectional elliptical arc shape as shown in FIG. 5A, an inverted V-shaped cross-section as shown in FIG. It can be formed in a trapezoidal shape as shown in c). Further, particularly preferably, the waterproof dam 3 is formed so that the cross-sectional shape of the waterproof weir 3 is a right-angled triangular shape in which the base end portion 5 on the flat material portion 2 side forms a right-angled apex as shown in FIG. Is. At this time, the rising angle θ from the base end portion 5 forming the right-angled apex is 90 °.

  FIG. 1 shows a state in which a drainer 10 is attached to a loose part of a roof of a building. In the illustrated example, a waterproof sheet 19 such as asphalt roofing is laid on the field 7 installed on the rafter 14, and the drainer 10 is arranged along the edge of the wife side on the upper surface of the field 7. Yes. The drainage 10 is arranged such that the flat member 2 side is disposed on the wife side with respect to the waterproof weir 3, and an appropriate interval is provided between the drainage 10 and the wife side edge of the field 7. ing. In this state, a fixing tool 13 such as a screw is driven into the fixed piece 4 of the drainer 10 until reaching the field 7, whereby the drainer 10 is fixed to the field 7.

  The roofing material 8 is installed on the field 7 via a waterproof sheet 19, and at this time, on the wife side of the roof, between the roofing material 8 and the field 7, A waterproof weir 3 and a fixed piece 4 are interposed. Further, the end surface of the roof material 8 on the wife side faces the closing piece 24 of the drainer 10.

  Further, a spacer 17 made of a folded plate material is attached. The spacer 17 includes a fixing piece 26 arranged between the draining drain 10 and the end edge of the field 7, and an end surface of the field 7 that hangs downward from the end edge of the fixing piece 26. Opposing drooping piece 27, standing piece 28 that rises upward from the opposite edge of fixed piece 26 and is arranged along the outer surface side of end piece 24, and drains from the upper end edge of standing piece 28 10 and an upper piece 29 that extends toward the roofing material 8 and is disposed above the roofing material 8, and a holding piece 30 that extends obliquely downward from the edge of the upper piece 29. A fixing tool 13 such as a screw is driven into the fixing piece 4 of the spacer 17 until reaching the field 7, whereby the spacer 17 is fixed to the field 7. At the same time, the upper piece 29 of the spacer 17 is arranged above the upper end of the closing piece 24 of the drainer 10 so that the side opposite to the fixed piece 4 of the drainer 10 is prevented from floating upward. Then, the drainer 10 is stably fixed without being lifted.

  In addition, a threading bag 18 made of a folded plate material is attached to cover the loose portion of the roof. The threading packet 18 includes the roofing material 8, the draining drainage 10, the spacing spacer 17, the vertical wrapping piece 31 arranged on the wives side of the field 7, and the top piece of the spacer 17 from the upper end of the longitudinal wrapping piece 31 29 is formed in an L-shaped cross section having an upper wrapping piece 32 extending up to above 29. The end portion of the upper wrapping piece 32 is arranged along the upper piece 29 of the spacer 17, and the fixing piece 34 is extended along the holding piece 30 of the detachable spacer 17 from the end edge of the upper wrapping piece 32. It extends obliquely downward. The edge of the fixed piece 34 is in contact with the upper surface of the roof material 8. Moreover, the lower end of the vertical wrapping piece 31 is extended below the field 7, and the draining piece 33 is extended toward the diagonally lower outer side from the lower end. This threading packet 18 is driven so that the fixing tool 13 such as a screw is inserted into the vertical wrapping piece 31 until it reaches the field 7, and the fixing tool 13 such as a screw penetrates the holding piece 30. The vertical wrapping piece 31 is fixed by this.

  Reference numeral 15 in the figure denotes a windbreak plate, and reference numeral 16 denotes a makeup windbreak attached to the outer surface of the windbreak plate 15.

  In such a lazy structure of the roof, the lava portion of the roof is covered with a packet 18 if it passes through, but rainwater or the like enters the inside of the package 18 and further the roof material 8 and the field 7. Even if water enters between the two, the water penetration is blocked by the waterproof weir 3 and drained from the eaves side of the roof along the longitudinal direction of the waterproof weir 3.

  Further, in such a loose structure of the roof, when the drainage 10 is installed, the fixing piece 4 may be fixed to the field 7 with an appropriate fixing tool 13, and the drainage 10 is installed. It becomes very easy and does not require a highly skilled worker.

  Further, the waterproof weir 3 has a shape in which the cross-sectional shape on the surface orthogonal to the longitudinal direction is between the base end portion 5 on the flat member 2 side and the base end portion 6 on the fixed piece 4 side as described above. In addition, since the width dimension in the direction perpendicular to the longitudinal direction of the waterproof weir 3 is formed so as to be narrower toward the roof material 8 side, the resistance to the load from above is high. Even if a worker or the like steps on the roofing material 8 above the waterproof weir 3 to apply a load from above, the waterproof weir 3 is not easily crushed. The waterproof action by the waterproof weir 3 can be maintained.

  Moreover, since the waterproof dam 3 is formed so as to be narrower toward the roof material 8 side as described above, the flat material portion 2 is pushed in by another member such as the spacer 17 and the arrangement position is fixed. The gap between the base end portions 5 and 6 on both sides of the waterproof weir 3 is narrowed by shifting to the piece 4 side or shifting the fixing position of the fixed piece 4 to the wife side when the drainer 10 is installed. Even if a situation occurs, it is suppressed that the cross-sectional shape of the waterproof weir 3 protrudes outside the two base end portions 5 and 6 (see FIG. 6). For this reason, the high durability with respect to the load from the upper side of the waterproof dam 3 can be maintained, and waterproof performance can be maintained.

  Furthermore, when the cross-sectional shape of the waterproof weir 3 is formed so that the base end portion 6 on the flat material portion 2 side is a right triangle having a right apex, the side surface of the waterproof weir 3 on the fixed piece 4 side. Since the dimension from the apex portion to the base end portion 5 is shorter on the side surface on the flat member portion 2 side than the fixing member 4 even if the flat member portion 2 side is lifted upward as shown in FIG. Lifting upward is suppressed. For this reason, it is possible to prevent the fixed piece 4 from being lifted from the field 7, and a high mounting strength is imparted to the drainer 10 and the waterproof performance of the drainer 10 is maintained.

  In addition, when a plurality of drainage drainers 10 are connected and installed along the roof wife in the eaves ridge direction, as shown in FIG. By simply overlapping the edge of the drainage 10 on the other side, the other waterproof weir 3 can be stacked on one waterproof weir 3, eliminating the need for expanding or narrowing the waterproof weir 3, It is possible to connect the drainer 10 easily.

  Next, as 2nd embodiment, what formed the roof draining material 1 as the valley draining 11 provided in the trough part of the roof of a building is shown to FIG.

  The trough drainer 11 is also formed of a folded plate material obtained by bending a sheet of metal or the like.

  This trough drainer 11 has a shape in which the edges of two flat plate members 2 are connected by a water stop portion 20 that protrudes upward in an inverted V-shaped cross section. The two flat members 2 are formed so as to incline downward toward the water stop 20 along the shape of the valley of the roof. A waterproof weir 3 is provided at the end of each flat member 2 opposite to the water stop portion 20 so as to protrude upward over the entire end edge. A fixed piece 4 extends from a base end 6 on the opposite side to the base end 5 on the material part 2 side. The flat member 2 and the fixed piece 4 are formed flush with each other. The shape of the waterproof weir 3 in the valley drainer 11 is also formed in the same manner as the case of the drainer 10.

  FIG. 3 shows a state in which the valley drainer 11 is attached to the valley of the roof of the building. In the illustrated example, the field 7 is installed on the valley 21 and the haze 22 so as to incline downward from both sides of the valley 21 toward the valley 21. A waterproof sheet 19 such as asphalt roofing is laid on the field 7, and a valley drainer 11 is disposed along the valley on the upper surface of the field 7. The valley water drain 11 is configured such that the water stop 20 is disposed along the valley 21 and each flat member 2 is disposed on the field 7 on both sides of the valley 21. In this state, the fixing piece 13 such as a screw is driven into the fixed piece 4 of the valley drain 11 until it reaches the field 7, whereby the valley drain 11 is fixed to the field 7.

  The roofing material 8 is installed on the field 7 through a waterproof sheet 19. At this time, in the valley of the roof, the flat material part 2 of the valley drainer 11, waterproofing is provided between the roofing material 8 and the field 7. The weir 3 and the fixed piece 4 are interposed. In addition, the end surface of the roof material 8 on the valley side faces the water stop portion 20 of the valley drainer 11.

  In such a roof valley structure, rainwater or the like infiltrates from between the roof material 8 and the water stop 20 at the abutting portion between the roof materials 8 in the roof valley, and further, the roof material 8 and the field 7. Even if water enters between the two, the waterproof weir 3 prevents the water from entering. This water is drained from the eaves side of the roof along the longitudinal direction of the waterproof weir 3 or is accumulated on the water stopping portion 20 side along the inclination of the valley of the roof in the longitudinal direction of the water stopping portion 20. It will be drained from the eaves side of the roof.

  Also, in such a valley structure of the roof, as in the case of the above-described rake structure, when the valley drainer 11 is installed, the fixing piece 4 is fixed to the field 7 with an appropriate fixing tool 13. What is necessary is that the installation of the valley drainer 11 is very easy, and the worker does not need high skill.

  Further, the waterproof weir 3 has a shape in which the cross-sectional shape on the surface orthogonal to the longitudinal direction is between the base end portion 5 on the flat member 2 side and the base end portion 6 on the fixed piece 4 side as described above. In addition, since the width dimension in the direction perpendicular to the longitudinal direction of the waterproof weir 3 is formed so as to be narrower toward the roof material 8 side, the resistance to the load from above is high. Even when an operator or the like steps on the roof material 8 above the waterproof weir 3 and loads from above are applied to the waterproof weir 3, the waterproof weir 3 is not easily crushed. The waterproof action by the waterproof weir 3 can be maintained.

  Further, as described above, the waterproof weir 3 is formed so as to be narrower toward the roof material 8 side, so that the flat material portion 2 is pushed in such as by deforming the water stop portion 20 so as to spread on both sides. The arrangement position shifts to the fixed piece 4 side, or when the valley drainer 11 is installed, the fixed position of the fixed piece 4 shifts to the valley side, and the distance between the base end portions 5 and 6 on both sides of the waterproof weir 3 Even if such a situation occurs, the cross-sectional shape of the waterproof weir 3 is prevented from protruding to the outside of the two base end portions 5 and 6 (see FIG. 6). For this reason, the high durability with respect to the load from the upper side of the waterproof dam 3 can be maintained, and waterproof performance can be maintained.

  Further, when the cross-sectional shape of the waterproof weir 3 is formed so that the base end portion 5 on the flat material portion 2 side is a right-angled triangle having a right-angled apex, the side surface of the waterproof weir 3 on the fixed piece 4 side Since the dimension from the apex portion to the base end portion 5 is shorter on the side surface on the flat member portion 2 side than the fixing member 4 even if the flat member portion 2 side is lifted upward as shown in FIG. Lifting upward is suppressed. For this reason, it can prevent that the fixed piece 4 floats from the field 7, and the waterproof performance of the valley drainer 11 is maintained while high attachment strength is provided to the valley drainer 11.

  When a plurality of valley drainers 11 are connected and installed along the roof valley, as shown in FIG. 8A, the other valley drainer 11 is placed on the edge of one valley drainer 11. By simply stacking the edges, the other waterproof weir 3 can be stacked on one waterproof weir 3, eliminating the need to expand or narrow the waterproof weir 3, making it easy to connect the valley drainage 11. Is something that can be done.

  As described above, the drainage drainage 10 and the valley drainage 11 have been described for the roof drainage material 1, but the form of the roof drainage material 1 is not limited to these, and is interposed between the field 7 and the roofing material 8. As long as it drains water, an appropriate one can be adopted.
