Description

本発明は、戸建て住宅に好適に採用される床下配管構造に関する。   The present invention relates to an underfloor piping structure that is suitably employed in a detached house.

従来の戸建て住宅においては、図１０に示すように、基礎１００に沿って排水主管１０１を屋外の地中に配管し、屋内のトイレ、風呂場、洗濯機、洗面所、台所などの各排水箇所からの排水管１０２を、屋外の排水主管１０１に接続していた。   In a conventional detached house, as shown in FIG. 10, a drain main pipe 101 is piped along the foundation 100 to the ground outdoors, and each drainage point such as an indoor toilet, bathroom, washing machine, washroom, kitchen, etc. Was connected to an outdoor drain main pipe 101.

なしNone

しかしながら、上記の配管構造では、排水主管１０１を屋外の地中に埋設する作業が大変であり、特に、埋設スペースが少ない場合は、埋設作業がし辛いという問題があった。   However, in the above-described piping structure, it is difficult to embed the drain main pipe 101 in the ground outdoors, and there is a problem that the burying work is difficult particularly when the burial space is small.

しかも、排水管１０２を屋外の排水主管１０１に接続する部分には、必ず排水桝１０３を設置しなければならないので、多くの排水桝１０３が必要になり、部品コストが増大するだけでなく、各排水桝１０３の蓋が地面に露出するため外観が悪くなるという問題があった。   Moreover, since the drainage pipe 103 must be installed at the portion connecting the drainage pipe 102 to the outdoor drainage main pipe 101, a lot of drainage pipes 103 are required, which not only increases the parts cost, Since the lid of the drainage basin 103 is exposed to the ground, there is a problem that the appearance is deteriorated.

また、各排水管１０２は基礎貫通部材１０４を介して屋外へ導出しなければならないため、排水管１０２と同じ数の基礎貫通部材１０４が必要となり、部品コストが増大すると共に、該部材１０４の埋設作業が大変になるという問題もあった。   In addition, since each drain pipe 102 must be led to the outside via the foundation penetrating member 104, the same number of foundation penetrating members 104 as the drain pipe 102 are required, which increases the cost of parts and embeds the member 104. There was also a problem that the work became difficult.

本発明は上記の問題に対処すべくなされたもので、その目的とするところは、床下の空間を利用して配管することにより、施工性の大幅な向上と、排水桝や基礎貫通部材の大幅な削減と、外観の向上等を図ると共に、基礎貫通部材の本体の固定作業が極めて容易で、基礎コンクリートの打設時に本体が動く恐れがなく確実に本体を基礎中の所定位置に埋設することができる床下配管構造を提供することにある。   The present invention has been made to cope with the above-mentioned problems, and the purpose of the present invention is to significantly improve the workability by piping the space under the floor, and greatly improve the drainage basin and the foundation penetrating member. The main body of the foundation penetrating member is extremely easy to fix, and there is no risk of the main body moving when placing concrete, so that the main body is securely embedded at a predetermined position in the foundation. An object of the present invention is to provide an underfloor piping structure.

上記目的を達成するため、本発明の床下配管構造は、床下に排水主管を管固定具により流れ勾配をつけて配管固定し、屋内の各排水箇所からの排水枝管を排水主管に接続すると共に、排水主管の下流端を基礎貫通部材を介して屋外排水管に接続した床下配管構造であって、基礎貫通部材の本体の開口した上部の外側面に、複数の突片を上下方向に間隔をあけて設け、この突片を基礎の鉄筋に線材で結び付けて本体を固定したことを特徴とするものである。 In order to achieve the above object, the underfloor piping structure of the present invention fixes the drainage main pipe under the floor by using a pipe fixture with a flow gradient, and connects drainage branch pipes from indoor drainage points to the drainage main pipe. , an underfloor piping structure connected to the outdoor discharge pipe through the foundation penetrating member downstream end of the drainage main pipe, the open outer side of the upper portion of the main body of the foundation penetrating member, the spacing a plurality of projecting pieces in the vertical direction The main body is fixed by opening and connecting the projecting piece to a reinforcing bar of the foundation with a wire.

本発明の床下配管構造においては、上記突片に孔があいていることが好ましい。 In underfloor piping structure of the present invention, it is preferable that the hole in the protrusion is free.

本発明の床下配管構造は、排水主管を地中に埋設する作業が不要となり、管固定具によって流れ勾配をつけながら簡単に排水主管を床下に配管することができる。そして、各排水箇所からの排水枝管は管継手を用いて排水主管に接続されるので、排水主管が接続される屋外排水管の屈曲点にのみ排水桝を埋設すれば良くなり、排水桝の使用個数を大幅に削減することができる。また、基礎貫通部材も排水主管の下流端に一つ設置すればよいので、使用個数を大幅に削減することができる。この床下配管構造は、上記のように排水主管を地中へ埋設する必要がなく、排水桝や基礎貫通部材を大幅に削減できるので、施工性が大幅に向上し、施工費や部品コストの削減が可能となる。また、屋外排水管の屈曲点のみに排水桝を設置すればよいので、地面に露出する排水桝の蓋の数が１〜２個となり、外観も向上する。更に、基礎貫通部材の本体の開口した外側面に複数の突片を上下間隔をあけて設け、この突片を基礎の鉄筋に線材で結び付けて本体を固定しているので、基礎貫通部材の本体の固定作業が極めて容易であり、しかも、基礎コンクリートの打設時に本体が動く恐れがなく確実に本体を高さ位置の調整をして基礎中の所定位置に埋設することができる。 The underfloor piping structure of the present invention eliminates the need to bury the drain main pipe in the ground, and can easily pipe the drain main pipe under the floor while providing a flow gradient with the pipe fixture. And since the drainage branch pipe from each drainage point is connected to the drainage main pipe using a pipe joint, it is only necessary to bury the drainage basin at the bending point of the outdoor drainage pipe to which the drainage main pipe is connected. The number used can be greatly reduced. In addition, since only one foundation penetrating member may be installed at the downstream end of the drain main pipe, the number of used members can be greatly reduced. This underfloor piping structure eliminates the need to bury the drain main pipe in the ground as described above, and drastically reduces drainage dredging and foundation penetrating members, greatly improving workability and reducing construction costs and parts costs. Is possible. Moreover, since a drainage basin should just be installed only in the bending point of an outdoor drainage pipe, the number of the lids of the drainage basin exposed to the ground will be 1-2, and an external appearance will also improve. Further, it provided at a vertical spacing a plurality of projecting pieces in the opened outer side surface of the main body of the foundation through member, so securing the unit in connection with the protrusion on the reinforcing bars of the basic wire material, the basal through-member body The fixing work is extremely easy, and it is possible to embed the main body in a predetermined position in the foundation by adjusting the height position without fear of moving the main body when placing the foundation concrete.

また、基礎貫通部材の本体の開口した上部の外側面に上下方向に間隔をあけて設けられた突片に孔があいている床下配管構造は、基礎コンクリートの打設時に、その孔を利用して該突片を基礎の鉄筋に線材で結び付けることによって、本体を簡単且つ確実に固定することができる。 Further, underfloor piping structure holes projecting piece provided at intervals in the vertical direction on the outer sides of the open top of the main body of the foundation penetrating member is Ai, the striking設時the foundation concrete, by utilizing the hole Thus, the main body can be fixed easily and reliably by connecting the projecting piece to the reinforcing bar of the foundation with a wire.

以下、図面を参照して本発明の具体的な実施形態を詳述する。   Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

図１に示す床下配管構造によれば、屋内の床下空間１に合成樹脂製の排水主管２が管固定具３により流れ勾配をつけて直線状に配管固定され、屋内のトイレ、風呂場、洗濯機、洗面所、台所等の各排水箇所からの合成樹脂製の排水枝管４が合成樹脂製の管継手５によって排水主管２に接続されている。そして、この排水主管２の下流端は、基礎貫通部材６を介して屋外排水管７に接続されている。この屋外排水管７は公共桝８に通じており、その途中の屈曲部には合成樹脂製の宅内排水桝９が埋設されている。   According to the underfloor piping structure shown in FIG. 1, a synthetic resin drainage main pipe 2 is linearly fixed to the indoor underfloor space 1 by a pipe fixture 3 with a flow gradient, and is used for indoor toilets, bathrooms, and laundry. A synthetic resin drainage branch pipe 4 from each drainage point such as a machine, a washroom, and a kitchen is connected to a drainage main pipe 2 by a synthetic resin pipe joint 5. And the downstream end of this drain main pipe 2 is connected to the outdoor drain pipe 7 via the foundation penetration member 6. This outdoor drainage pipe 7 leads to a public pit 8, and a synthetic drainage basin 9 made of synthetic resin is embedded in a bent portion in the middle.

一方、排水主管２の上流端は基礎１０の外側面に露出し、この露出した上流端にキャップ１１が脱着可能に取付けられている。従って、このキャップ１１を外して排水主管２の上流端から排水主管２の内部を覗くと、簡単に排水主管２内部のゴミ詰まり等の点検を行うことができ、ゴミ等があれば、該上流端から線状ないし棒状の掃除具等を排水主管２に挿入して取り除くことができるので、メンテナンスが容易である。   On the other hand, the upstream end of the drainage main pipe 2 is exposed to the outer surface of the foundation 10, and a cap 11 is detachably attached to the exposed upstream end. Therefore, when the cap 11 is removed and the inside of the drainage main pipe 2 is looked into from the upstream end of the drainage main pipe 2, it is possible to easily check for clogging of dust inside the drainage main pipe 2, and if there is dust, the upstream Since a linear or rod-like cleaning tool or the like can be inserted into the drain main pipe 2 and removed from the end, maintenance is easy.

上記のような床下配管構造は、排水主管２を地中に埋設する作業が不要であるため、施工性が大幅に向上し、施工費の低減が可能となる。しかも、基礎貫通部材６は一つあればよく、排水桝９も屋外排水管７の屈曲部にのみ埋設すればよいので、基礎貫通部材６や排水桝９の使用個数が大幅に減少し、部品コストの削減も可能となる。また、排水桝９の使用個数が少なくなれば、地面に露出する蓋の数も少なくなるので、家屋周辺の美観が向上する。   The underfloor piping structure as described above does not require the work of burying the drain main pipe 2 in the ground, so that the workability is greatly improved and the construction cost can be reduced. Moreover, since only one foundation penetrating member 6 is required and the drainage basin 9 only needs to be embedded in the bent portion of the outdoor drainage pipe 7, the number of the foundation penetrating member 6 and drainage basin 9 used is greatly reduced, and the parts Costs can be reduced. Further, if the number of drainage basins 9 used is reduced, the number of lids exposed to the ground is also reduced, so that the aesthetics around the house are improved.

排水主管２を固定する管固定具３は、図２，図３に示すように、固定板３ａ、左右一対の棒ネジ３ｂ，３ｂ、管支持材３ｃ、管押え材３ｄ、ゴム材３ｅなどの主要部品からなるものであって、ゴム材３ｅを除いて他の部品は全て金属製である。   As shown in FIGS. 2 and 3, the pipe fixture 3 for fixing the drainage main pipe 2 includes a fixing plate 3a, a pair of left and right bar screws 3b and 3b, a pipe support member 3c, a pipe presser 3d, and a rubber member 3e. It consists of main parts, and all the other parts are made of metal except for the rubber material 3e.

この管固定具３の固定板３ａは、その中央部３０ａが細長い帯状に***し、四隅がビス３ｆで基礎１０に固定されている。そして、この固定板３ａの***した中央部３０ａに、左右一対の棒ネジ３ｂ，３ｂが回転自在かつ抜出し不能に立設されている。これらの棒ネジ３ｂ，３ｂは、管支持材３ｃの左右両端部の固定ナット３０ｃ，３０ｃに下方から螺挿され、棒ネジ３ｂ，３ｂを回すと、管支持材３ｃが上下に移動して高さの調節が行われるようになっている。   The fixing plate 3a of the tube fixing tool 3 has a central portion 30a raised in the shape of an elongated band, and four corners are fixed to the foundation 10 with screws 3f. A pair of left and right bar screws 3b, 3b are erected on the raised central portion 30a of the fixed plate 3a so as to be rotatable and unremovable. These bar screws 3b and 3b are screwed into the fixing nuts 30c and 30c at the left and right ends of the tube support member 3c from below, and when the bar screws 3b and 3b are turned, the tube support member 3c moves up and down to increase the height. Adjustment of the height is made.

管押え材３ｄは逆Ｕ字状に曲成された部材であって、図３に示すように、管押え材３ｄの中心線上にはスリット３０ｄが形成されている。このスリット３０ｄは、図２（Ｂ）に示すように管押え材３ｄを開けたとき、一方の棒ネジ３ｂが管押え材３ｄに当たらないようにするためのものである。この管押え材３ｄは、外側に折れ曲がった一端３１ｄを管支持材３ｃの係合孔３１ｃに挿入して抜けないように係合させることにより、管支持材３ｃに対して回動可能に取付けられている。そして、管押え材３ｄの他端３２ｄは、管支持材３ｃに取付けられたロック部材３２ｃの係止爪と係合して、解除可能にロックされている。従って、管押え材３ｄの他端３２ｄを外側に引いてロック部材３２ｃの係止爪との係合を解除すれば、管押え材３ｄを簡単に開けることができる。尚、３３ｄは、管押え材３ｄの開閉操作をしやすくするための操作片である。   The tube pressing member 3d is a member bent in an inverted U shape, and as shown in FIG. 3, a slit 30d is formed on the center line of the tube pressing member 3d. The slit 30d is for preventing one of the bar screws 3b from hitting the tube pressing member 3d when the tube pressing member 3d is opened as shown in FIG. The tube pressing member 3d is rotatably attached to the tube support member 3c by inserting one end 31d bent outward to the engagement hole 31c of the tube support member 3c so as not to come off. ing. The other end 32d of the tube pressing member 3d is engaged with a locking claw of a lock member 32c attached to the tube support member 3c and is releasably locked. Therefore, if the other end 32d of the tube pressing member 3d is pulled outward to disengage the locking claw of the lock member 32c, the tube pressing member 3d can be easily opened. Reference numeral 33d denotes an operation piece for facilitating the opening / closing operation of the tube pressing member 3d.

更に、管支持材３ｃの中央上面と、管押え材３ｄの左右側部及び上部の内面には、排水主管２に弾接する防振用のゴム材３ｅが固着されている。このゴム材３ｅは、両端に一対のリング部を有するもので、これらのリング部が適度な弾力性を有し、排水主管２に対して安定良く弾接して良好な防振作用を発揮できるものである。   Further, a vibration isolating rubber material 3e elastically contacting the drainage main pipe 2 is fixed to the central upper surface of the pipe support member 3c and the left and right side portions and the upper inner surface of the pipe presser 3d. This rubber material 3e has a pair of ring portions at both ends, and these ring portions have appropriate elasticity, and can be elastically contacted stably with respect to the drainage main pipe 2 to exhibit a good anti-vibration effect. It is.

上記の管固定具３を用いると、左右の棒ネジ３ｂ，３ｂを回して管支持材３ｃの高さを調節することにより、排水主管２に所定の流れ勾配を付けて配管することができ、管押え材３ｄを閉じて管押え材３ｄの他端３２ｄをロック部材３２ｃによりロックするだけで、簡単に排水主管２を固定することができる。そして、このように固定した状態では、ゴム材３ｅが排水主管２の周囲に弾接して良好な防振作用を発揮するため、地震等の振動を受けても排水主管２の破損を防止することができる。   When the pipe fixture 3 is used, the drainage main pipe 2 can be piped with a predetermined flow gradient by turning the left and right bar screws 3b, 3b to adjust the height of the pipe support member 3c. The drainage main pipe 2 can be easily fixed simply by closing the pipe presser 3d and locking the other end 32d of the pipe presser 3d with the lock member 32c. And in the state fixed in this way, since the rubber material 3e elastically contacts the circumference of the drainage main pipe 2 and exhibits a good vibration-proofing action, it is possible to prevent the drainage main pipe 2 from being damaged even when subjected to vibration such as an earthquake. Can do.

排水主管２を屋外排水管７に接続する前記の基礎貫通部材６は、図４，図５に示すように、その本体６ａ、高さ調節用のアジャスター６ｂ、さや管６ｃ、防水パッキン付き直角エルボ６ｄ、内管６ｅ、立上り管６ｆ、蓋材６ｇ、キャップ６ｈなどの主要部品からなるものであって、蓋材６ｇやキャップ６ｈはゴム又は軟質合成樹脂の成形品であるが、他の部品は全て硬質合成樹脂で成形された成形品である。   As shown in FIGS. 4 and 5, the basic penetration member 6 for connecting the drain main pipe 2 to the outdoor drain pipe 7 includes a main body 6a, a height adjuster 6b, a sheath pipe 6c, and a right angle elbow with waterproof packing. 6d, inner pipe 6e, riser pipe 6f, lid member 6g, cap 6h, etc. The lid member 6g and cap 6h are molded products of rubber or soft synthetic resin, but other parts are All are molded products made of hard synthetic resin.

基礎貫通部材６の本体６ａは、上部にアジャスター挿入口６０ａが形成され、側面下部にさや管接続口６１ａが形成されている。そして、アジャスター挿入口６０ａには高さ調節用のアジャスター６ｂが上下可動に挿入され、さや管接続口６１ａにはさや管６ｃが接続されている。この本体６ａの開口した上部の外側面には、孔のあいた突片６２ａが上下方向に間隔をあけて複数形成され、基礎コンクリートの打設時に、突片６２ａの孔に線材１２を通して、該突片６２ａを基礎の鉄筋１０ａに線材１２で結び付けることによって、本体６ａを高さ位置の調整をして簡単に固定することができるようになっている。 The main body 6a of the base penetrating member 6 has an adjuster insertion port 60a formed at the top and a sheath connection port 61a formed at the bottom of the side surface. A height adjusting adjuster 6b is inserted into the adjuster insertion port 60a in a vertically movable manner, and a sheath tube 6c is connected to the sheath tube connection port 61a. The open outer sides of the upper portion of the main body 6a, the projecting piece 62a of perforated holes are formed at a distance in the vertical direction, the droplet設時the foundation concrete, through the wire 12 into the hole of the projecting piece 62a, projecting By connecting the piece 62a to the basic reinforcing bar 10a with the wire 12, the main body 6a can be easily fixed by adjusting the height position .

アジャスター６ｂは、図７に示すような前方後円形の平面形状を有する筒体に形成され、これに対応して、本体６ａのアジャスター挿入口６０ａも前方後円形の平面形状を有する開口とされている。そして、アジャスター挿入口６０ａの上端部内面には、横向きの二つの凸条６３ａ，６３ａが形成され、図４に示すようにアジャスター６ｂを最上位置まで引き上げると、アジャスター６ｂの下端外縁６０ｂが二つの凸条６３ａ，６３ａの間に嵌まり込んで仮止めされるようになっている。   The adjuster 6b is formed in a cylindrical body having a front rear circular plane shape as shown in FIG. 7, and correspondingly, the adjuster insertion port 60a of the main body 6a is also an opening having a front rear circular plane shape. Yes. Then, two laterally extending ridges 63a and 63a are formed on the inner surface of the upper end of the adjuster insertion port 60a. When the adjuster 6b is pulled up to the uppermost position as shown in FIG. 4, the lower end outer edge 60b of the adjuster 6b has two. The protrusions 63a and 63a are fitted and temporarily fixed.

このアジャスター６ｂの上端開口には、ゴミや異物の侵入を防止する蓋材６ｇが被着されており、図７に示すように、この蓋材６ｇの上面には、切抜き口を手で簡単に切抜くことができるように断面Ｖ字形の切取り溝６０ｇが形成されている。そして、切抜かれる部分には、上方に突き出すツマミ６２ｇが形成されている。尚、６１ｇは、蓋材６ｇの裏面周縁部から内側に突き出した爪片であって、被着した蓋材６ｇがアジャスター６ａから剥脱しないようにアジャスター６ｂの上端フランジ部６１ｂに係止されるものである。   A lid member 6g that prevents intrusion of dust and foreign substances is attached to the upper end opening of the adjuster 6b. As shown in FIG. 7, a cutout opening is easily formed on the upper surface of the lid member 6g by hand. A cut groove 60g having a V-shaped cross section is formed so as to be cut out. And the knob 62g which protrudes upwards is formed in the part cut out. Reference numeral 61g denotes a claw piece projecting inward from the peripheral edge of the back surface of the lid member 6g, which is locked to the upper end flange portion 61b of the adjuster 6b so that the adhered lid member 6g does not peel off from the adjuster 6a. It is.

基礎貫通部材６の本体６ａの内部には、防水パッキン付き直角エルボ６ｄが安定良く内蔵され、このエルボ６ｄの上流側接続口６０ｄに立上り管６ｆが接続されている。一方、エルボ６ｄの下流側接続口６１ｄの内面には環状溝６２ｄが形成され、この環状溝６２ｄにリング状の防水パッキン６３ｄが取付けられている。そして、図４，図５に示すように、内管６ｅが上記エルボ６ｄの下流側接続口６１ｄに差し込まれて脱着可能に接続され、防水パッキン６３ｄによって水密性が確保されている。この内管６ｅの先端には、該内管６ｅと屋外排水管７を接続するための管継手６ｉが取付けられている。   A right angle elbow 6d with waterproof packing is stably built in the main body 6a of the base penetrating member 6, and a rising pipe 6f is connected to an upstream connection port 60d of the elbow 6d. On the other hand, an annular groove 62d is formed on the inner surface of the downstream connection port 61d of the elbow 6d, and a ring-shaped waterproof packing 63d is attached to the annular groove 62d. As shown in FIGS. 4 and 5, the inner pipe 6e is inserted into the downstream connection port 61d of the elbow 6d so as to be detachable, and watertightness is secured by the waterproof packing 63d. A pipe joint 6i for connecting the inner pipe 6e and the outdoor drain pipe 7 is attached to the tip of the inner pipe 6e.

また、さや管６ｃの先端には、土砂や基礎コンクリートの侵入を防止するキャップ６ｈが取付けられている。このキャップ６ｈは、図８に示すように、円形の端板６０ｈと外筒部６１ｈと内筒部６２ｈを備えたもので、端板６０ｈには、屋外排水管７を挿通するための切抜き口を手で簡単に切抜くことができるように断面Ｖ字形の切取り溝６３ｈが形成されており、切抜かれる部分にはツマミ６４ｈが形成されている。   Moreover, the cap 6h which prevents intrusion of earth and sand or foundation concrete is attached to the tip of the sheath pipe 6c. As shown in FIG. 8, the cap 6h is provided with a circular end plate 60h, an outer cylinder portion 61h, and an inner cylinder portion 62h. The end plate 60h has a cut-out opening through which the outdoor drain pipe 7 is inserted. A cut groove 63h having a V-shaped cross section is formed so that it can be easily cut out by hand, and a knob 64h is formed at the cutout portion.

このキャップ６ｈは、図４，図９に示すように、外筒部６１ｈがさや管６ｃに外嵌され、内筒部６２ｈがさや管６ｃと管継手６ｉとの間に挿入された状態で取付けられるため、管継手６ｉや内管６ｅが常にさや管６ｃと同心的位置関係を保ち、内管６ｅが斜め下方へ傾斜するのを防止できる利点がある。   As shown in FIGS. 4 and 9, the cap 6h is attached in a state where the outer cylinder portion 61h is fitted over the sheath tube 6c and the inner cylinder portion 62h is inserted between the sheath tube 6c and the pipe joint 6i. Therefore, there is an advantage that the pipe joint 6i and the inner pipe 6e always maintain a concentric positional relationship with the sheath pipe 6c, and the inner pipe 6e can be prevented from being inclined obliquely downward.

以上のような基礎貫通部材６を基礎１０中に埋設する場合は、図４に示すように、アジャスター６ｂを最上位置まで引き上げて凸条６３ａで仮止めし、さや管６ｃ先端のキャップ６ｈをコンクリート型枠１３に当接させて、本体６ａを所定の深さに設置し、本体６ａの突片６２ａを線材１２で鉄筋１０ａに結び付けて本体６ａを固定する。そして、基礎コンクリートを打設し、コンクリートを乾燥固化させて基礎１０を完成する。このコンクリート打設時には、さや管６ｃの先端にキャップ６ｈが被せられているので、コンクリートがさや管６ｃの内部に侵入することはない。また、アジャスター６ｂの上端開口には蓋材６ｇが被着されているので、ゴミや異物が侵入することもない。   When embedding the foundation penetrating member 6 as described above in the foundation 10, as shown in FIG. 4, the adjuster 6b is pulled up to the uppermost position and temporarily fixed by the ridge 63a, and the cap 6h at the end of the sheath pipe 6c is fixed to the concrete. The main body 6a is placed at a predetermined depth in contact with the mold 13, and the projecting piece 62a of the main body 6a is connected to the reinforcing bar 10a with the wire 12 to fix the main body 6a. Then, foundation concrete is placed, and the concrete is dried and solidified to complete the foundation 10. At the time of placing the concrete, since the cap 6h is put on the tip of the sheath tube 6c, the concrete does not enter the sheath tube 6c. In addition, since the lid 6g is attached to the upper end opening of the adjuster 6b, dust and foreign matter do not enter.

基礎１０が完成すると、図５に示すように、アジャスター６ｂを押し下げて蓋材６ｇと基礎１０の表面をほぼ面一にすると共に、蓋材６ｇのツマミ６２ｇを指で摘まみながら蓋材６ｇを切取り溝６０ｇに沿って切抜くことにより切抜き口を形成し、この蓋材６ｇの切抜き口を通じて、排水主管２と基礎貫通部材６の立上り管６ｆを直角エルボ６ｊで接続する。一方、コンクリート型枠１３を除去してさや管６ｃ先端のキャップ６ｈを基礎１０の外側面に露出させ、キャップ６ｈのツマミ６４ｈを指で摘まみながらキャップ６ｈを切取り溝６３ｈに沿って切抜くことにより切抜き口を形成し、このキャップ６ｈの切抜き口から屋外排水管７をさや管６ｃ内部の管継手６ｉに差し込んで屋外排水管７と内管６ｅを接続する。   When the foundation 10 is completed, as shown in FIG. 5, the adjuster 6b is pushed down so that the surface of the lid member 6g and the foundation 10 are substantially flush with each other, and the lid member 6g is grasped with the finger 62g of the lid member 6g. A cutout opening is formed by cutting along the cutout groove 60g, and the drainage main pipe 2 and the rising pipe 6f of the base penetrating member 6 are connected by a right angle elbow 6j through the cutout opening of the lid member 6g. On the other hand, the concrete formwork 13 is removed to expose the cap 6h at the end of the sheath 6c to the outer surface of the foundation 10, and the cap 6h is cut out along the cut groove 63h while grasping the knob 64h of the cap 6h with a finger. A cutout opening is formed by this, and the outdoor drainage pipe 7 is inserted into the pipe joint 6i inside the sheath pipe 6c from the cutout opening of the cap 6h to connect the outdoor drainage pipe 7 and the inner pipe 6e.

上記のように、基礎１０に埋設した基礎貫通部材６を介して排水主管２と屋外排水管７を接続すると、基礎貫通部材６の内管６ｅが防水パッキン付き直角エルボ６ｄの下流側接続口６１ｄに脱着可能に差込接続されているため、下流側接続口６１ｄの防水パッキン６３ｄが劣化して防水性が低下したような場合には、内管６ｃを直角エルボ６ｄから引き抜き、本体６ａから直角エルボ６ｄを立上り管６ｆと共に取り出して新しいものに交換することができる。また、蓋材６ｇやキャップ６ｈは取り除かず、切抜き口を形成して、排水主管２と立上り管６ｆとの接続や、屋外排水管７と内管６ｅとの接続を行うため、施工後にアジャスター６ｂの上端開口からゴミや異物が本体６ａに入ったり、基礎１０の外側の土砂がさや管６ｃの内部に侵入することはない。そして、基礎貫通部材６は、アジャスター６ｂで高さ調節できるため、基礎１０中の所望の深さに埋設することができ、更にさや管６ｃや内管６ｅの長さを適宜変更すれば、基礎１０の外側面から所望の奥行きのところに埋設することができる。   As described above, when the drainage main pipe 2 and the outdoor drainage pipe 7 are connected via the foundation penetrating member 6 embedded in the foundation 10, the inner pipe 6e of the foundation penetrating member 6 is connected to the downstream connection port 61d of the right angle elbow 6d with waterproof packing. When the waterproof packing 63d of the downstream side connection port 61d deteriorates and the waterproof property is lowered, the inner pipe 6c is pulled out from the right angle elbow 6d and is perpendicular to the main body 6a. The elbow 6d can be taken out together with the riser 6f and replaced with a new one. In addition, the lid 6g and the cap 6h are not removed, and a cut-out opening is formed to connect the drainage main pipe 2 and the riser pipe 6f and to connect the outdoor drainage pipe 7 and the inner pipe 6e. Dust and foreign matter do not enter the main body 6a from the upper end opening of the, and earth and sand outside the foundation 10 do not enter the inside of the sheath 6c. Since the height of the foundation penetrating member 6 can be adjusted by the adjuster 6b, it can be embedded at a desired depth in the foundation 10, and if the length of the sheath pipe 6c or the inner pipe 6e is changed as appropriate, the foundation penetration member 6 can be embedded. 10 can be embedded at a desired depth from the outer surface.

以上の説明から明らかなように、本発明の床下配管構造は、排水主管２を地中に埋設する作業が不要となり、管固定具３によって流れ勾配をつけながら簡単に排水主管２を配管固定できるので、施工性が大幅に向上し、しかも、基礎貫通部材６は排水主管２の下流端に一つ設置すればよく、排水桝９も屋外排水管７の屈曲点にのみ埋設すればよいので、基礎貫通部材６や排水桝９の使用個数が大幅に減少して部品コストの低減が可能となり、また、排水桝９の使用個数の減少によって地面に露出する排水桝９の蓋の数が減少するので家屋周辺の外観も向上するといった効果を奏する。そして、排水主管２を直線状に配管し、排水主管２の上流端を基礎１０の外側面に露出させてキャップ１１を脱着可能に取付けたものは、キャップ１１を外して排水主管２内部のゴミ詰まり等の点検作業や清掃作業を簡単を行うことができるので、メンテナンスが容易であるといった効果も奏する。更に、基礎貫通部材６の本体６ａの開口した上部の外側面に複数の突片６２ａを上下方向に間隔をあけて設け、この突片６２ａを基礎１０の鉄筋１０ａに線材１２で結び付けて本体６ａを固定しているので、基礎貫通部材６の本体６ａの固定作業が極めて容易であり、しかも、基礎コンクリートの打設時に本体６ａが動く恐れがなく確実に本体６ａを高さ位置の調整をして基礎中の所定位置に埋設することができるといった効果も奏する。 As is clear from the above description, the underfloor piping structure of the present invention eliminates the need to embed the drain main pipe 2 in the ground, and can easily fix the drain main pipe 2 while providing a flow gradient with the pipe fixture 3. Therefore, the workability is greatly improved, and furthermore, only one foundation penetrating member 6 should be installed at the downstream end of the drainage main pipe 2, and the drainage basin 9 should be buried only at the bending point of the outdoor drainage pipe 7, The number of base penetrating members 6 and drainage basins 9 used can be greatly reduced, and the cost of parts can be reduced, and the number of drainage basins 9 exposed to the ground can be reduced due to the decrease in the number of drainage basins 9 used. As a result, the appearance around the house is improved. The drain main pipe 2 is connected in a straight line, the upstream end of the drain main pipe 2 is exposed to the outer surface of the base 10 and the cap 11 is detachably attached. Since inspection work such as clogging and cleaning work can be easily performed, there is an effect that maintenance is easy. Furthermore, spaced a plurality of projecting pieces 62a in the vertical direction in the opened outer side surface of the upper portion of the main body 6a of the basal through-member 6, the body 6a in connection with wire 12 the protrusion 62a reinforcing bars 10a of the foundation 10 Therefore, it is very easy to fix the main body 6a of the foundation penetrating member 6, and the height of the main body 6a is adjusted without fail to move the main body 6a when placing the foundation concrete. The effect that it can embed in the predetermined position in the foundation is also produced.
