　本開示は、防水構造に関する。本開示の一実施形態に係る防水構造について、図１～図８に基いて説明する。まず、一実施形態に係る防水構造を備える建物１について説明する。 The present disclosure relates to a waterproof structure. A waterproof structure according to an embodiment of the present disclosure will be described with reference to FIGS. First, a building 1 having a waterproof structure according to one embodiment will be described.

　図１に示すように、建物１は、屋根１２と、上端が屋根１２よりも上方に突出する壁１１と、を備える。建物１は、軒方向の両端部に配置される壁１１（外壁）を備え、両側の壁１１の間に配置される屋根１２を備える。ここで、軒方向とは、屋根１２の窓、戸口等を有する壁１４の面に沿う水平な方向Ｘをいうものとする（以下、軒方向Ｘとする）。また、軒棟方向とは、軒方向と直交し、屋根１２の傾斜に沿う方向Ｙをいうものとする（以下、軒棟方向Ｙとする）。また、軒棟方向Ｙのうちの軒側をＹ１、棟側をＹ２とする。 As shown in FIG. 1, the building 1 includes a roof 12 and a wall 11 whose upper end protrudes above the roof 12. The building 1 includes walls 11 (outer walls) arranged at both ends in the eave direction, and a roof 12 arranged between the walls 11 on both sides. Here, the eaves direction refers to a horizontal direction X along the surface of the wall 14 having windows, doorways, and the like of the roof 12 (hereinafter, eaves direction X). The eaves ridge direction refers to a direction Y orthogonal to the eaves direction and along the slope of the roof 12 (hereinafter, eaves ridge direction Y). In the eave ridge direction Y, the eave side is Y1 and the ridge side is Y2.

　図１に示す建物１は、両側の壁１１とその間の屋根１２とにより、一つの独立した居住空間を有する、一つの建物により構成される。なお、図示しないが、建物は、軒方向に間隔をあけて配置される三つ以上の壁と、隣接する二つの壁の間にそれぞれ配置される屋根と、を有する連棟（リンクハウス）により構成されてもよい。連棟は、隣接する二つの壁とその間に配置される屋根とで囲まれる空間が、それぞれ独立した居住空間となる。連棟では、軒方向の両端部に配置される壁が外壁となる。また、連棟では、外壁以外の壁、すなわち、隣接する二つの居住空間の間に位置する壁が界壁となる。建物 The building 1 shown in FIG. 1 is constituted by one building having one independent living space by the walls 11 on both sides and the roof 12 therebetween. Although not shown, the building is a linked building having three or more walls arranged at intervals in the eave direction and a roof arranged between two adjacent walls. It may be configured. In a multi-story building, the space surrounded by two adjacent walls and the roof placed between them is an independent living space. In a multi-story building, the walls located at both ends in the eave direction are the outer walls. In a multi-story building, a wall other than the outer wall, that is, a wall located between two adjacent living spaces is a boundary wall.

　また本実施形態では、建物１は、ＰＣパネル（precast concrete panel）が連結されるいわゆるＷＰＣ（wall precast concrete）工法により建築されている。ＷＰＣ工法では、複数のＰＣパネルが連結されることにより、基礎上に、一階及び二階の壁（外壁および界壁）、一階の天井（二階の床）及び二階の天井が形成される。なお、本実施形態の建物１は二階建てであるが、建物は、平屋（一階建て）であってもよいし、三以上の階を有してもよい。また、建物は、ＷＰＣ工法により建築されたものでなくてもよい。 In the present embodiment, the building 1 is constructed by a so-called WPC (wall precast concrete) method in which PC panels (precast concrete panels) are connected. In the WPC method, a plurality of PC panels are connected to form a first-floor and second-floor wall (outer wall and boundary wall), a first-floor ceiling (a second-floor floor), and a second-floor ceiling on a foundation. Although the building 1 of the present embodiment is a two-story building, the building may be a single-story building (one-story) or may have three or more floors. The building does not have to be constructed by the WPC method.

　壁１１が屋根１２よりも上方に突出していると、火災が発生して屋根１２が燃焼している場合に、火炎は壁１１を越えて燃え広がりにくい。特に、建物が連棟である場合、燃焼している屋根から壁（界壁）を挟んで隣接する屋根に延焼しにくくなる。 (4) If the wall 11 protrudes above the roof 12, the fire hardly spreads beyond the wall 11 when a fire occurs and the roof 12 is burning. In particular, when the building is a multi-story building, it is difficult to spread a fire from a burning roof to an adjacent roof with a wall (wall) interposed therebetween.

　壁１１の上端の屋根１２からの突出高さが高い程、延焼防止効果が期待できる。壁１１の上端の屋根１２からの突出高さは、特に限定されないが、例えば１００ｍｍ、２００ｍｍ、３００ｍｍ、それ以上に設定されるのが好ましい。程 The higher the height of the upper end of the wall 11 protruding from the roof 12, the more the effect of preventing fire spread can be expected.

　次に、建物１が備える防水構造について説明する。防水構造は、図５に示すように、壁１１と、屋根１２と、水受け部材６と、を備える。 Next, the waterproof structure of the building 1 will be described. As shown in FIG. 5, the waterproof structure includes a wall 11, a roof 12, and a water receiving member 6.

　水受け部材６は、隙間１３に配置されて軒棟方向Ｙに沿って伸びる。水受け部材６は、隙間１３の軒棟方向Ｙの全長にわたって配置されるのが好ましいが、特に隙間１３の軒棟方向Ｙの全長にわたって配置されなくてもよい。水受け部材６の軒方向Ｘにおける一端部６０１（埋設部６２）は、壁１１の一側面１１０に埋設されている。水受け部材６の軒方向Ｘにおける他端部６０２（載置部６３）は、瓦桟３の上側でかつ瓦４の下側に位置する。更に具体的に説明する。 The water receiving member 6 is disposed in the gap 13 and extends along the eave ridge direction Y. The water receiving member 6 is preferably disposed over the entire length of the gap 13 in the eaves ridge direction Y, but is not particularly required to be disposed over the entire length of the gap 13 in the eaves ridge direction Y. One end 601 (embedded portion 62) of the water receiving member 6 in the eaves direction X is embedded in one side surface 110 of the wall 11. The other end 602 (mounting portion 63) of the water receiving member 6 in the eaves direction X is located above the roof tile 3 and below the roof tile 4. This will be described more specifically.

　図７に示すように、水受け部材６は、本体部６１と、埋設部６２と、載置部６３と、を有し、鋼等の金属により形成される。本体部６１は、隙間１３に位置し、上方に開口するＣ字状をした断面形状を有する。 As shown in FIG. 7, the water receiving member 6 has a main body 61, a buried portion 62, and a mounting portion 63, and is formed of a metal such as steel. The main body 61 has a C-shaped cross section that is located in the gap 13 and that opens upward.

　埋設部６２は、水受け部材６の軒方向Ｘにおける一端部６０１となるもので、本体部６１から側方に突出するＬ字状をした断面形状を有する。図５に示すように、埋設部６２は、壁１１の一側面１１０に埋設される。本体部６１の一側面１１０側の端部は、瓦４よりも上側の位置にまで突出している。埋設部６２は、瓦４よりも上側の位置において、壁１１の一側面１１０に埋設されている。埋設部６２は、壁１１の一側面１１０に形成された凹部１１１に挿入される。埋設部６２が挿入された凹部１１１には、シリコンあるいはモルタル等からなる充填材１１２が充填される。これにより、水受け部材６の軒方向Ｘにおける一端部６０１が、壁１１の一側面１１０に埋設されるが、埋設方法は限定されず、また、埋設以外の方法により一端部６０１が一側面１１０に接触するようにしてもよい。 The buried portion 62 serves as one end 601 of the water receiving member 6 in the eaves direction X, and has an L-shaped cross-sectional shape protruding laterally from the main body 61. As shown in FIG. 5, the buried portion 62 is buried in one side surface 110 of the wall 11. The end on the one side surface 110 side of the main body 61 protrudes to a position above the roof tile 4. The buried portion 62 is buried in one side surface 110 of the wall 11 at a position above the roof tile 4. The buried portion 62 is inserted into a concave portion 111 formed on one side surface 110 of the wall 11. The recess 111 into which the buried portion 62 is inserted is filled with a filler 112 made of silicon, mortar, or the like. As a result, one end 601 of the water receiving member 6 in the eaves direction X is buried in the one side surface 110 of the wall 11, but the embedding method is not limited. May be contacted.

　図７に示すように、載置部６３は、水受け部材６の軒方向Ｘにおける他端部６０２となるものである。図５に示すように、本体部６１の端部から外方に側出して、瓦桟３の上に載置される。載置部６３は、釘等の固定具６３１により、瓦桟３に固定される。 As shown in FIG. 7, the mounting portion 63 is the other end 602 in the eaves direction X of the water receiving member 6. As shown in FIG. 5, the body part 61 protrudes outward from an end of the body part 61 and is placed on the tile bar 3. The mounting portion 63 is fixed to the roof tile 3 by a fixing tool 631 such as a nail.

　上述した屋根構造においては、瓦４に降った雨水が瓦４上を軒側Ｙ１に向けて流下する。瓦４に降った雨水のうちの一部の雨水は、軒方向Ｘに流れ、瓦４の壁１１側の端部と壁１１との間から流下する。この場合、雨水は壁１１を伝って建物１内に浸入することになる。 In the above-mentioned roof structure, the rainwater that has fallen on the tile 4 flows down on the tile 4 toward the eaves side Y1. Part of the rainwater that has fallen on the tile 4 flows in the eaves direction X and flows down from between the end of the tile 4 on the wall 11 side and the wall 11. In this case, the rainwater will enter the building 1 along the wall 11.

　本実施形態では、壁１１の一側面１１０と瓦桟３の一端面３０の間の隙間１３に、水受け部材６が配置される。瓦４に降った雨水が瓦４の壁１１側の端部に到達し、屋根１２と壁１１との間から雨水が流下（落下）しようとしても、雨水は水受け部材６に受けられる。これにより、雨水が屋根１２と壁１１との間から建物１内に浸入するのが抑制される。 In the present embodiment, the water receiving member 6 is disposed in the gap 13 between the one side surface 110 of the wall 11 and the one end surface 30 of the tile bar 3. Even if the rainwater falling on the tile 4 reaches the end of the tile 4 on the side of the wall 11 and the rainwater tries to flow down (fall) from between the roof 12 and the wall 11, the rainwater is received by the water receiving member 6. This suppresses rainwater from entering the building 1 from between the roof 12 and the wall 11.

　また、水受け部材６の一端部６０１（埋設部６２）は、瓦４よりも上側の位置において、壁１１の一側面１１０に埋設されている。このため、瓦４上を流れる雨水は、水受け部材６の一側面１１０に埋設されている箇所には到達しにくい。これにより、瓦４上を流れる雨水が、水受け部材６の一側面１１０に埋設されている箇所を通って建物１内に浸入するのが抑制される。一端 One end 601 (embedded portion 62) of water receiving member 6 is embedded in one side surface 110 of wall 11 at a position above tile 4. For this reason, it is difficult for the rainwater flowing on the roof tile 4 to reach the portion buried in the one side surface 110 of the water receiving member 6. This suppresses rainwater flowing on the tile 4 from entering the building 1 through a portion buried in the one side surface 110 of the water receiving member 6.

　本実施形態では、図５に示すように、防水構造は、更に水切り部材７を有する。水切り部材７は、軒棟方向Ｙに沿って伸びる。水切り部材７は、隙間１３の軒棟方向Ｙ全長にわたって配置されるのが好ましいが、特に隙間１３の軒棟方向Ｙの全長にわたって配置されなくてもよい。水切り部材７の軒方向Ｘにおける一端部７０１（埋設部７２）は、壁１１の一側面１１０に埋設されている。では In the present embodiment, as shown in FIG. 5, the waterproof structure further has a drainer 7. The drainer 7 extends in the eaves ridge direction Y. The draining member 7 is preferably arranged over the entire length of the gap 13 in the eaves ridge direction Y. However, the drainage member 7 may not be particularly arranged over the entire length of the gap 13 in the eaves ridge direction Y. One end 701 (embedded portion 72) of the drainer 7 in the eaves direction X is embedded in one side surface 110 of the wall 11.

　図８に示すように、水切り部材７は、本体部７１と、埋設部７２と、縦部７３と、を有し、鋼等の金属により形成される。埋設部７２は、水切り部材７の軒方向Ｘにおける一端部７０１に位置し、図５に示すように、壁１１の一側面１１０に埋設される。埋設部７２は、Ｌ字状をした断面形状を有する。埋設部７２は、壁１１の一側面１１０に形成された凹部１１３に挿入される。凹部１１３は、凹部１１１よりも上側に位置する。埋設部７２が挿入された凹部１１３には、シリコンあるいはモルタル等からなる充填材１１４が充填される。これにより、水切り部材７の軒方向Ｘにおける一端部７０１が、壁１１の一側面１１０に埋設されるが、埋設方法は限定されず、また、埋設以外の方法により一端部７０１が一側面１１０に接触するようにしてもよい。水 As shown in FIG. 8, the drainer 7 has a main body 71, a buried portion 72, and a vertical portion 73, and is formed of a metal such as steel. The embedded portion 72 is located at one end 701 of the draining member 7 in the eaves direction X, and is embedded in one side surface 110 of the wall 11 as shown in FIG. The buried portion 72 has an L-shaped cross section. The buried portion 72 is inserted into a concave portion 113 formed on one side surface 110 of the wall 11. The recess 113 is located above the recess 111. The recess 113 into which the buried portion 72 is inserted is filled with a filler 114 made of silicon, mortar, or the like. Thereby, the one end 701 in the eaves direction X of the draining member 7 is buried in the one side surface 110 of the wall 11, but the embedding method is not limited, and the one end 701 is connected to the one side surface 110 by a method other than the embedding. You may make it contact.

　埋設部７２の端部から縦部７３が下方に突出する。縦部７３の下端部から、斜めに本体部７１が突出する。本体部７１の軒方向Ｘにおける他端部７０２は、瓦４の上側に位置する。水切り部材７は、水受け部材６の一側面１１０に埋設されている箇所の上側を覆う。縦 The vertical portion 73 protrudes downward from the end of the embedded portion 72. The main body 71 projects obliquely from the lower end of the vertical part 73. The other end 702 of the main body 71 in the eaves direction X is located above the roof tile 4. The draining member 7 covers an upper side of a portion embedded in one side surface 110 of the water receiving member 6.

　水切り部材７が設けられない場合、壁１１の一側面１１０を流下した雨水は、水受け部材６の一側面１１０に埋設されている箇所に到達し、建物１内に浸入するおそれがある。場合 If the draining member 7 is not provided, the rainwater flowing down one side surface 110 of the wall 11 may reach a portion buried in the one side surface 110 of the water receiving member 6 and enter the building 1.

　水受け部材６が設けられることにより、壁１１の一側面１１０を流下した雨水は、水受け部材６の一側面１１０に埋設されている箇所に到達するまでに、水切り部材７により瓦４の上に誘導される。これにより、壁１１の一側面１１０を流下した雨水が、水受け部材６の一側面１１０に埋設されている箇所を通って建物１内に浸入するのが抑制される。 By providing the water receiving member 6, the rainwater flowing down one side surface 110 of the wall 11 reaches the place buried in the one side surface 110 of the water receiving member 6, and the rainwater is drained on the roof 4 by the draining member 7. Is induced. This suppresses rainwater flowing down one side surface 110 of the wall 11 from entering the building 1 through a portion buried in the one side surface 110 of the water receiving member 6.
