この発明は、縦樋等の管材が貫通する庇その他の屋根又は床等において、その貫通部の防水性を高めるための防水構造に関する。 The present invention relates to a waterproof structure for enhancing the waterproofness of a penetrating portion in a roof or other roof or floor through which a pipe member such as a vertical rod penetrates.
集合住宅等の建物において、屋上やバルコニーからの排水が流される縦樋を、外廊下の外壁等から張り出す庇を貫通させて設置することがある。そのような縦樋その他の管材の貫通部には、その下側に水が侵入しないように何らかの防水処理を施す必要がある。 In a building such as an apartment house, a vertical gutter that drains water from the rooftop or balcony may be installed through a gutter that projects from the outer wall of the outer corridor. It is necessary to apply some waterproofing treatment to the penetration portion of such pipes and other pipe materials so that water does not enter the lower side thereof.
庇(１)における縦樋(３)の貫通部の防水構造としては、例えば図７に示すようなものがある。この構造においては、合板からなる庇(１)の天板(８)と、その天板(８)上面に敷設された防水板(５)とに、それぞれ縦樋(３)が貫通する開口部(７)(９)が設けられている。そして、それら開口部(７)(９)から庇(１)の内部に水が侵入しないように、縦樋(３)外周面と防水板(５)上面とに跨ってシーリング材(20)を付着させることで、防水処理が施されている。 As a waterproof structure of the penetration part of the vertical rod (3) in the rod (1), for example, there is a structure as shown in FIG. In this structure, an opening through which the vertical gutter (3) passes through the top board (8) of the gutter (1) made of plywood and the waterproof board (5) laid on the top board (8). (7) and (9) are provided. Then, seal the sealing material (20) across the outer periphery of the vertical rod (3) and the top surface of the waterproof plate (5) so that water does not enter the inside of the rod (1) from the openings (7), (9). Waterproofing is performed by attaching.
なお、特許文献１には、建物の床において管材が貫通する開口部において、その管材に円筒状のパッキンを外嵌させて開口部の隙間を埋めることで、床における管材の貫通部において、その下側に水漏れするのを防止する構成が開示されている。 In addition, in patent document 1, in the opening part which a pipe material penetrates in the floor of a building, the cylindrical packing is externally fitted to the pipe material, and the gap of the opening part is filled, and in the penetration part of the pipe material in the floor, A configuration for preventing water leakage from the lower side is disclosed.
しかし、図７に示す従来の防水構造では、シーリング材(20)の断面形状が三角形状になっているため切れ目が入りやすく、その切れ目から侵入した水が、防水板(５)の開口部(７)より防水板(５)裏面を伝って防水板(５)と天板(８)との間に入り込んでしまう恐れがあった。このような浸水が起こると、天板(８)が腐食して強度低下を起こす恐れがあるため、シーリング材(20)に切れ目が入りにくいようにシーリング施工を改善するか、又は、防水板(５)の開口部に万が一水が侵入した場合でも、その水が防水板(５)の裏側に入り込まないようにする必要があった。 However, in the conventional waterproof structure shown in FIG. 7, since the cross-sectional shape of the sealing material (20) is triangular, a break is easily formed, and the water that has entered from the break is formed in the opening ( 7) There is a risk that the waterproof plate (5) may enter the space between the waterproof plate (5) and the top plate (8) along the back surface. If such flooding occurs, the top plate (8) may be corroded and the strength may be reduced. Therefore, the sealing work may be improved to prevent the sealing material (20) from being broken, or the waterproof plate ( Even if water intrudes into the opening of 5), it is necessary to prevent the water from entering the back side of the waterproof board (5).
すなわち、庇その他の屋根又は床等における強度低下を防止するために、その上面に設けられた防水層の裏側に水が侵入するのを防止できるような防水処理の開発が望まれていた。なお、特許文献１には、そのような目的で防水層の裏側への浸水を防止する構成については開示されていない。 That is, in order to prevent the strength of the roof or other floors from being lowered, it has been desired to develop a waterproof treatment that can prevent water from entering the back side of the waterproof layer provided on the upper surface thereof. Note that Patent Document 1 does not disclose a configuration for preventing water from entering the back side of the waterproof layer for such a purpose.
そこで、この発明は、上記の不具合を解消して、縦樋等の管材が庇その他の屋根又は床等を貫通する構造において、上面に設けられた防水層の裏側における防水性の向上を図ることができる防水構造を提供することを目的とする。 In view of this, the present invention eliminates the above-mentioned problems and improves the waterproof property on the back side of the waterproof layer provided on the upper surface in a structure in which a pipe material such as a vertical fence penetrates a fence or other roof or floor. It is an object to provide a waterproof structure capable of
上記の課題を解決するため、この発明は、上面に防水板が敷設された屋外の屋根又は床等を縦樋その他の管材が貫通する構造において、その管材が貫通する開口部が前記防水板に設けられ、その開口部からの水が防水板の裏側へ侵入するのを防止する水切り部が、前記開口部周縁に沿って下向きに突出して設けられていることを特徴とする。 In order to solve the above-described problems, the present invention provides a structure in which a vertical wall or other pipe material penetrates an outdoor roof or floor or the like having a waterproof board laid on the upper surface thereof, and an opening through which the pipe material penetrates the waterproof board. A draining portion that is provided and prevents the water from the opening from entering the back side of the waterproof board is provided so as to protrude downward along the periphery of the opening.
また、前記防水板は、前記水切り部を一体に備えている。さらに、防水板の前記開口部を塞ぐようにして、シーリング材を防水板と縦樋外周面とに跨って付着してなる。 Moreover, the said waterproof board is integrally provided with the said draining part. Further, the sealing material is adhered across the waterproof board and the vertical outer periphery so as to close the opening of the waterproof board.
またさらに、前記防水板は、屋根又は床等の傾斜面又は水平面を構成する横材の上面に敷設されており、前記管材外周面とその管材が貫通する横材の開口部内周面との間の間隙に、その間隙を仕切るようにして筒状の仕切り部が設けられている。 Still further, the waterproof plate is laid on the top surface of a horizontal member constituting an inclined surface or a horizontal surface such as a roof or a floor, and between the pipe member outer peripheral surface and the inner peripheral surface of the opening of the cross member through which the pipe member passes. A cylindrical partition portion is provided in the gap so as to partition the gap.
場合によって、この発明は、上面に防水層が設けられた屋外の屋根又は床等を縦樋その他の管材が貫通する構造において、前記防水層上面より立ち上がる立上がり部が、前記管材外周面に対して間隙を空けて取り囲むようにして設けられ、その間隙にシーリング材が充填されてなることを特徴とする。 In some cases, according to the present invention, in a structure in which downpipe or other pipe material penetrates an outdoor roof or floor having a waterproof layer provided on the upper surface, a rising portion rising from the upper surface of the waterproof layer is formed with respect to the outer peripheral surface of the tube material. It is provided so as to surround a gap, and the gap is filled with a sealing material.
また、前記立上がり部は、円環状その他の環状に形成されている。 The rising portion is formed in an annular shape or other annular shape.
さらに、前記間隙の底部にシーリング材充填用のバックアップ材を取り付け、そのバックアップ材の上側にシーリング材を充填してなる。 Further, a backup material for filling a sealing material is attached to the bottom of the gap, and the sealing material is filled on the upper side of the backup material.
またさらに、前記立上がり部に対して、その立上がり部下端より外側に向かって張り出すフランジ部が連結されるか又は一体に設けられ、そのフランジ部下面が前記防水層上面に取り付けられてなる。 Furthermore, a flange portion projecting outward from the lower end of the rising portion is connected to or integrally formed with the rising portion, and the lower surface of the flange portion is attached to the upper surface of the waterproof layer.
加えて、前記立上がり部外周面と前記フランジ部上面とに跨るようにしてシーリング材が付着されてなる。 In addition, a sealing material is adhered so as to straddle the rising portion outer peripheral surface and the flange portion upper surface.
この発明によれば、縦樋等の管材が貫通する防水板の開口部周縁に沿って、その開口部からの水が防水板の裏側へ侵入するのを防止する水切り部が設けられているため、防水板の開口部に万が一水が侵入した場合でも、その水は水切り部を伝って下方に落とし込まれることとなる。すなわち、防水板の開口部に侵入した水が防水板の裏面を伝っていく恐れがないため、防水板の下側の部材が耐水性に乏しい合板等からなっている場合であっても、その合板等の部材が浸水により強度低下を起こす危険を回避することができる。また、その水切り部は、防水板が一体に備えるものであるため、施工現場において水切り部を形成する作業を省略して、現場施工の簡略化を図ることができる。 According to this invention, the draining portion for preventing water from the opening from entering the back side of the waterproof board is provided along the periphery of the opening of the waterproof board through which the pipe material such as the vertical gutter penetrates. Even if water enters the opening of the waterproof plate, the water will be dropped down through the draining portion. That is, since there is no risk that water that has entered the opening of the waterproof plate will travel along the back surface of the waterproof plate, It is possible to avoid a risk that a member such as a plywood is lowered in strength due to water immersion. Moreover, since the water draining part is provided integrally with the waterproof plate, the work for forming the water draining part at the construction site can be omitted, and the construction at the site can be simplified.
さらに、防水板の開口部を塞ぐようにして、シーリング材を防水板と縦樋外周面とに跨って付着しているため、防水板の開口部へ水が侵入することを極力回避することができる。 Furthermore, since the sealing material is adhered across the waterproof board and the vertical outer peripheral surface so as to close the opening of the waterproof board, it is possible to avoid water from entering the opening of the waterproof board as much as possible. it can.
またさらに、上面に防水板が敷設された横材の開口部内周面と管材外周面との間の間隙に、その間隙を仕切る仕切り部が設けられているため、防水板の開口部から水が侵入したとしても、その水は仕切り部によって遮られることとなる。すなわち、これによって、横材の開口部内周面に水が付着することを防ぐことができ、浸水による横材の強度低下を防ぐことができる。 Furthermore, since a partition portion is provided in the gap between the inner peripheral surface of the opening portion of the horizontal member and the outer peripheral surface of the pipe member on which the waterproof plate is laid on the upper surface, water is supplied from the opening portion of the waterproof plate. Even if it enters, the water will be blocked by the partition. That is, this can prevent water from adhering to the inner peripheral surface of the opening of the cross member, and can prevent a decrease in strength of the cross member due to water immersion.
一方、防水層上面より立ち上がる立上がり部を、縦樋等の管材外周面に対して間隙を空けて取り囲むようにして設けた場合は、その間隙にシーリング材を充填することで所要のシーリング深さが確保されて、シーリング材に切れ目が発生しにくくなるため、そのシーリング部における防水性を高めることができる。すなわち、これにより、防水層の裏側に水が侵入する恐れを解消することができ、防水層の裏側に設けられた合板等の部材が浸水することがないため、その部材の浸水による強度低下を回避することができる。 On the other hand, when the rising part that rises from the upper surface of the waterproof layer is provided so as to surround the outer peripheral surface of the pipe material such as a vertical fence with a gap, the required sealing depth is reduced by filling the gap with a sealing material. Since it is ensured and it becomes difficult to generate a cut in the sealing material, the waterproof property in the sealing portion can be enhanced. That is, this can eliminate the risk of water intruding into the back side of the waterproof layer, and members such as plywood provided on the back side of the waterproof layer will not be submerged. It can be avoided.
また、前記の間隙の底部にシーリング材充填用のバックアップ材を取り付けて、そのバックアップ材の上側にシーリング材を充填することにより、充填時においてシーリング材が不要な部分にまで流れ込むことを防ぐことができ、確実で効率的なシーリング施工を行うことができる。 Further, by attaching a backup material for filling the sealing material to the bottom of the gap and filling the sealing material on the upper side of the backup material, it is possible to prevent the sealing material from flowing into unnecessary portions during filling. Yes, reliable and efficient sealing can be performed.
さらに、立上がり部下端より外側に向かって張り出すフランジ部が設けられており、そのフランジ部下面を防水層上面に取り付けているため、立上がり部の取付け状態を安定させることができる。 Furthermore, since the flange part projecting outward from the lower end of the rising part is provided and the lower surface of the flange part is attached to the upper surface of the waterproof layer, the mounting state of the rising part can be stabilized.
加えて、これら立上がり部外周面とフランジ部上面とに跨るようにしてシーリング材が付着されているため、立上がり部とフランジ部との接合部分からの浸水を防止することができる。 In addition, since the sealing material is attached so as to straddle the outer peripheral surface of the rising portion and the upper surface of the flange portion, it is possible to prevent water from entering from the joint portion between the rising portion and the flange portion.
以下、この発明の実施形態を図面に基づいて詳細に説明する。先ず、図１乃至図３に基づいて、この発明の第１の実施形態について説明する。図１は、例えば集合住宅の外壁(２)に、その外壁面より外側に張り出して設けられた庇(１)を示している。この庇(１)は、外廊下等に対応するようにして、外壁(２)の壁面方向に沿って連続して設けられている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows, for example, a gutter (1) provided on the outer wall (2) of an apartment house so as to protrude outward from the outer wall surface. This ridge (1) is provided continuously along the wall surface direction of the outer wall (2) so as to correspond to the outer corridor or the like.
庇(１)には、屋上若しくはバルコニー等からの排水が通される縦樋(３)が、上下方向に貫通して設けられている。庇(１)の上面は、軒先側に向かって緩やかな下り傾斜となっている。ただし、庇(１)の上面は、水平面となっていても良いものとする。 A vertical gutter (3) through which drainage from the rooftop or balcony is passed is provided in the gutter (1) in a vertical direction. The upper surface of the ridge (1) has a gentle downward slope toward the eaves side. However, the upper surface of the ridge (1) may be a horizontal plane.
なお、庇(１)の軒先には軒樋(４)が設けられており、この軒樋(４)に庇(１)上の雨水が流し込まれるようになっている。また、軒樋(４)は、上記の縦樋(３)に対して図示しない配管を介して接続されている。 An eaves ridge (4) is provided at the eaves of the ridge (1), and rainwater on the ridge (1) is poured into the eaves ridge (4). Further, the eaves rod (4) is connected to the vertical rod (3) via a pipe (not shown).
図２において、(８)は、庇(１)の傾斜面を構成する横材としての天板を示している。天板(８)は、例えば合板からなっており、縦樋(３)が貫通する開口部(９)を備えている。なお、庇(１)の上面が水平面となっている場合は、その水平面は天板(８)により構成されるものとする。 In FIG. 2, (8) has shown the top plate as a crosspiece which comprises the inclined surface of the ridge (1). The top plate (8) is made of plywood, for example, and includes an opening (9) through which the vertical gutter (3) passes. In addition, when the upper surface of the ridge (1) is a horizontal surface, the horizontal surface shall be comprised by the top plate (8).
天板(８)の上面には、例えば金属製の防水板(５)が敷設されている。この防水板(５)としては、例えばガルバニウム鋼板が好適に用いられる。防水板(５)には、縦樋(３)が貫通する開口部(７)が設けられている。この防水板(５)の開口部(７)は、天板(８)の開口部(９)周縁が露出しないように、天板(８)の開口部(９)よりも小径に形成されている。 On the top surface of the top plate (8), for example, a metal waterproof plate (5) is laid. As the waterproof plate (5), for example, a galvanium steel plate is preferably used. The waterproof plate (5) is provided with an opening (7) through which the vertical gutter (3) passes. The opening (7) of the waterproof plate (5) has a smaller diameter than the opening (9) of the top plate (8) so that the periphery of the opening (9) of the top plate (8) is not exposed. Yes.
そして、防水板(５)は、その開口部(７)からの水が防水板(５)の裏側へ侵入するのを防止する水切り部(６)を一体に備えている。水切り部(６)は、防水板(５)の開口部(７)周縁に沿って下向きに突出して設けられている。また、水切り部(６)は、開口部(７)の全周に亘って例えば円環状に形成されている。 And the waterproof board (5) is integrally provided with the draining part (6) which prevents the water from the opening part (7) from invading into the back side of the waterproof board (5). The draining part (6) protrudes downward along the periphery of the opening (7) of the waterproof board (5). Moreover, the draining part (6) is formed in the annular | circular shape, for example over the perimeter of the opening part (7).
これによって、防水板(５)の開口部(７)に水が侵入したとしても、その水は水切り部(６)を伝って下方に落とし込まれるため、防水板(５)の裏側へ水が回り込まないようになっている。従って、防水板(５)の開口部(７)に侵入した水が、防水板(５)の裏面を伝って天板(８)上面に付着することがないため、天板(８)が浸水することを防ぐことができるようになっている。なお、水切り部(６)は、防水板(５)とは別体に設けても良く、防水板(５)の開口部(７)周縁部に溶接若しくは接着等により取り付けるようにしても良い。 As a result, even if water enters the opening (7) of the waterproof board (5), the water is dropped downward through the draining part (6), so that water is discharged to the back side of the waterproof board (5). It is designed not to wrap around. Accordingly, water that has entered the opening (7) of the waterproof plate (5) does not adhere to the top surface of the top plate (8) through the back surface of the waterproof plate (5). Can be prevented. The draining part (6) may be provided separately from the waterproof board (5), and may be attached to the peripheral part of the opening (7) of the waterproof board (5) by welding or bonding.
防水板(５)の開口部(７)周縁部の下側には、縦樋(３)を上下方向に案内する縦樋ガイド材(11)が設けられている。縦樋ガイド材(11)は、縦樋(３)が貫通する例えば円筒状の仕切り部(12)と、その仕切り部(12)上端より外側に向かって張り出すフランジ部(13)とからなっている。 A vertical hook guide material (11) for guiding the vertical hook (3) in the vertical direction is provided below the peripheral edge of the opening (7) of the waterproof plate (5). The vertical rod guide material (11) is composed of, for example, a cylindrical partition portion (12) through which the vertical rod (3) passes, and a flange portion (13) projecting outward from the upper end of the partition portion (12). ing.
仕切り部(12)は、縦樋(３)外周面と天板(８)の開口部(９)内周面との間の間隙(10)において、その間隙(10)を仕切るようにして設けられている。また、仕切り部(12)の内径は、防水板(５)の開口部(７)の内径よりも大きくなるように形成されている。縦樋(３)外周面と仕切り部(12)の内周面との間の間隙(14)には、全周に亘って緩衝材(15)が介装されている。緩衝材(15)としては、エチレンプロピレンゴムその他の合成ゴムが好適に用いられる。 The partition part (12) is provided so as to partition the gap (10) in the gap (10) between the outer periphery of the vertical shaft (3) and the opening (9) of the top plate (8). It has been. Moreover, the inner diameter of the partition part (12) is formed to be larger than the inner diameter of the opening part (7) of the waterproof board (5). In the gap (14) between the outer circumferential surface of the vertical rod (3) and the inner circumferential surface of the partition portion (12), a cushioning material (15) is interposed over the entire circumference. As the buffer material (15), ethylene propylene rubber and other synthetic rubbers are preferably used.
フランジ部(13)は、図３に示すように、例えば矩形のプレート状に形成されており、その中央に例えば円形の開口部(16)が設けられている。フランジ部(13)は、設置状態において、天板(８)上面の開口部(９)周縁部と、防水板(５)下面の開口部(７)周縁部との間に介装されている。フランジ部(13)下面は、天板(８)上面に例えば接着により取り付けられており、フランジ部(13)上面は、防水板(５)下面に例えば接着により取り付けられている。 As shown in FIG. 3, the flange portion (13) is formed in a rectangular plate shape, for example, and a circular opening (16) is provided in the center thereof. In the installed state, the flange portion (13) is interposed between the peripheral portion of the opening (9) on the top surface of the top plate (8) and the peripheral portion of the opening (7) on the bottom surface of the waterproof plate (5). . The lower surface of the flange portion (13) is attached to the upper surface of the top plate (8) by, for example, adhesion, and the upper surface of the flange portion (13) is attached to the lower surface of the waterproof plate (5), for example, by adhesion.
これら仕切り部(12)及びフランジ部(13)は、例えば金属からなっている。そして、仕切り部(12)外周面の上端部とフランジ部(13)下面の開口部(16)周縁部とに跨って、スポット溶接した後に全周に亘ってシーリング材(17)を付着させることで、仕切り部(12)とフランジ部(13)とが連結されて縦樋ガイド材(11)が形成される。ただし、縦樋ガイド材(11)は、一体成形するようにしても良いものとする。 The partition part (12) and the flange part (13) are made of metal, for example. Then, the sealant (17) is attached over the entire circumference after spot welding across the upper end of the outer peripheral surface of the partition (12) and the opening (16) peripheral edge of the flange (13) lower surface. Thus, the partition portion (12) and the flange portion (13) are coupled to form the vertical guide member (11). However, the vertical hook guide member (11) may be integrally formed.
施工の際は、設置された天板(８)の開口部(９)に、縦樋ガイド材(11)の仕切り部(12)を上側から嵌め込んで、その縦樋ガイド材(11)のフランジ部(13)下面を天板(８)上面に接着する。続いて、そのようにして縦樋ガイド材(11)を取り付けた状態において、天板(８)の上面に防水板(５)を敷設する。このとき、防水板(５)の水切り部(６)の下端部が、縦樋ガイド材(11)の仕切り部(12)の内側に収まるようにする。 At the time of construction, the partition (12) of the vertical guide (11) is fitted into the opening (9) of the installed top plate (8) from above, and the vertical guide (11) The lower surface of the flange portion (13) is bonded to the upper surface of the top plate (8). Subsequently, the waterproof board (5) is laid on the top surface of the top board (8) in such a state that the vertical gutter guide member (11) is attached. At this time, the lower end portion of the draining portion (6) of the waterproof plate (5) is set to be inside the partition portion (12) of the vertical guide member (11).
そして、縦樋ガイド材(11)の仕切り部(12)に縦樋(３)を貫通させた状態において、仕切り部(12)の内側の間隙(14)における緩衝材(15)の上側にシーリング材(20)を充填するとともに、防水板(５)の上面と縦樋(３)外周面とに跨ってシーリング材(20)を付着する。これにより、防水板(５)の開口部(７)は、完全に塞がれた状態となる。 Then, in the state where the vertical rod (3) is passed through the partition portion (12) of the vertical rod guide material (11), sealing is performed on the upper side of the cushioning material (15) in the gap (14) inside the partition portion (12). The material (20) is filled, and the sealing material (20) is attached across the upper surface of the waterproof board (5) and the outer periphery of the vertical gutter (3). As a result, the opening (7) of the waterproof plate (5) is completely closed.
このように防水板(５)の開口部(７)を塞ぐようにして、シーリング材(20)を防水板(５)と縦樋(３)外周面とに跨って付着しているため、その開口部(７)からの水の侵入を極力回避することができる。また、シーリング材(20)に切れ目が入ることなどによって、防水板(５)の開口部(７)から万が一水が侵入した場合であっても、その水は上記の水切り部(６)の作用によって防水板(５)の裏側に入り込まないようになっている。 Since the sealing material (20) is adhered across the waterproof board (5) and the vertical gutter (3) outer peripheral surface so as to close the opening (7) of the waterproof board (5) in this way, Intrusion of water from the opening (7) can be avoided as much as possible. In addition, even if water enters the opening (7) of the waterproof plate (5) due to a cut in the sealing material (20), the water acts as the above-mentioned draining portion (6). This prevents the back of the waterproof board (5) from entering.
次に、図４乃至図６に基づいて、この発明の第２の実施形態について説明する。この実施形態では、上記の水切り部(６)を設けた構成に代えて、シーリングガイド材(30)を用いた構成となっており、シーリング施工の改善を図っている。 Next, based on FIG. 4 thru | or FIG. 6, 2nd Embodiment of this invention is described. In this embodiment, the sealing guide material (30) is used in place of the configuration provided with the above draining section (6), and the sealing work is improved.
シーリングガイド材(30)は、図４及び図５に示すように、防水層としての防水板(５)上面より立ち上がる例えば円環状の立上がり部(31)と、その立上がり部(31)下端より外側に向かって張り出すフランジ部(32)とからなっている。 As shown in FIGS. 4 and 5, the sealing guide member (30) rises from the upper surface of a waterproof plate (5) as a waterproof layer, for example, an annular rising portion (31) and the rising portion (31) outside the lower end. It consists of a flange part (32) projecting toward the side.
立上がり部(31)は、図５に示すように、縦樋(３)外周面に対して間隙(40)を空けて取り囲むようにして設けられている。なお、立上がり部(31)は、環状に形成されていれば良いものとし、その横断面の形状は必ずしも円形に限られず、楕円形又は多角形その他の形状であっても良いものとする。 As shown in FIG. 5, the rising portion (31) is provided so as to surround the outer periphery of the vertical rod (3) with a gap (40) therebetween. The rising portion (31) may be formed in an annular shape, and the shape of the cross section is not necessarily limited to a circle, and may be an ellipse, a polygon, or other shapes.
フランジ部(32)は、図４に示すように、例えば円形のプレート状に形成されており、その中央において立上がり部(31)下端の外形に対応した開口部(36)を備えている。また、フランジ部(32)は、図５に示す設置状態において、防水板(５)の開口部(７)を囲むようにして、防水板(５)上面に例えば接着により取り付けられている。 As shown in FIG. 4, the flange portion (32) is formed in a circular plate shape, for example, and has an opening (36) corresponding to the outer shape of the lower end of the rising portion (31) at the center thereof. Further, in the installed state shown in FIG. 5, the flange portion (32) is attached to the upper surface of the waterproof board (5) by, for example, adhesion so as to surround the opening (7) of the waterproof board (5).
これら立上がり部(31)及びフランジ部(32)は例えば金属からなっており、特にアルミニウムが好適に用いられる。そして、立上がり部(31)外周面の下端部とフランジ部(32)上面の開口部(36)周縁部とに跨って、スポット溶接した後に全周に亘ってシーリング材(33)を付着させることで、立上がり部(31)とフランジ部(32)とが連結されてシーリングガイド材(30)が形成される。ただし、シーリングガイド材(30)は、一体成形するようにしても良いものとする。 These rising portions (31) and flange portions (32) are made of, for example, metal, and aluminum is particularly preferably used. Then, the sealant (33) is attached to the entire periphery after spot welding across the lower end of the outer peripheral surface of the rising portion (31) and the opening (36) peripheral portion of the upper surface of the flange portion (32). Thus, the rising portion (31) and the flange portion (32) are connected to form the sealing guide member (30). However, the sealing guide member (30) may be integrally formed.
施工の際は、先ず、第１の実施形態と同様に、天板(８)に縦樋ガイド材(11)を取り付けた後に、天板(８)上に防水板(５)を敷設する。この状態において、防水板(５)の上面に、上記のようにシーリングガイド材(30)を取り付ける。このとき、図５に示すように、立上がり部(31)下端部の内周面と防水板(５)上面とに跨って、全周に亘ってシーリング材(37)を付着させる。これにより、防水板(５)上面とフランジ部(32)下面との間からの水の侵入を防止することができる。 At the time of construction, first, as in the first embodiment, after attaching the vertical guide material (11) to the top plate (8), the waterproof plate (5) is laid on the top plate (8). In this state, the sealing guide member (30) is attached to the upper surface of the waterproof board (5) as described above. At this time, as shown in FIG. 5, the sealing material (37) is attached over the entire circumference across the inner peripheral surface of the lower end portion of the rising portion (31) and the upper surface of the waterproof plate (5). Thereby, the penetration | invasion of the water from between a waterproof board (5) upper surface and a flange part (32) lower surface can be prevented.
続いて、図６に示すように、縦樋(３)外周面と立上がり部(31)内周面との間の間隙(40)の底部に、シーリング材充填用のバックアップ材(34)を取り付け、そのバックアップ材(34)の上側にシーリング材(35)を充填する。なお、バックアップ材(34)としては、樹脂発泡体その他の軟質性樹脂が好適に用いられる。 Subsequently, as shown in FIG. 6, a backup material (34) for filling the sealing material is attached to the bottom of the gap (40) between the outer periphery of the vertical shaft (3) and the rising part (31). The sealing material (35) is filled on the upper side of the backup material (34). As the backup material (34), a resin foam or other soft resin is preferably used.
このようにしてシーリングガイド材(30)を用いることで、所要のシーリング深さとなるようにシーリング材(35)を充填できるような間隙(40)が形成されるため、シーリング材(35)に切れ目が発生しにくく防水性に優れたシーリング施工が可能となる。これにより、防水板(５)の開口部(７)から水が侵入する恐れを解消することができ、浸水による天板(８)の強度低下を回避することができるようになっている。 By using the sealing guide material (30) in this way, a gap (40) is formed so that the sealing material (35) can be filled so as to have a required sealing depth. This makes it possible to perform sealing work with excellent waterproofness. Thereby, the possibility that water may enter from the opening (7) of the waterproof board (5) can be eliminated, and the strength reduction of the top board (8) due to water immersion can be avoided.
なお、第２の実施形態においても、第１の実施形態と同様に水切り部(６)を設けるようにしても良い。また、第２の実施形態において、その他の構成及び効果は第１の実施形態と同様であり、図において、第１の実施形態と同様の機能を有する部材については同符号を付してある。 In the second embodiment, a draining part (6) may be provided as in the first embodiment. In the second embodiment, other configurations and effects are the same as those of the first embodiment. In the figure, members having the same functions as those of the first embodiment are denoted by the same reference numerals.
この発明は、上記実施形態に限定されるものではなく、この発明の範囲内で上記実施形態に多くの修正及び変更を加え得ることは勿論である。例えば、上記実施形態においては、縦樋が庇を貫通する構造について説明したが、縦樋以外の給水管等の管材が庇を貫通する構造、又は縦樋その他の管材が庇以外の屋根若しくはバルコニー床その他の床等を貫通する構造に、この発明の防水構造を適用するようにしても良い。 The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, in the above-described embodiment, a structure in which a vertical gutter penetrates a fence has been described, but a structure in which a pipe such as a water supply pipe other than a gutter penetrates the gutter, or a roof or balcony in which a vertical gutter or other pipe material is other than a gutter You may make it apply the waterproof structure of this invention to the structure which penetrates a floor other floors.
