Description

本発明は、躯体内部に壁パネルを立設するユニットバスの浴室内に設置した給水器具へ湯、或は水、若しくは混合湯水を供給する配管の更新方法及び該方法に用いる蓋体構造に関するものである。   The present invention relates to a method for renewing a pipe for supplying hot water, water, or mixed hot water to a water supply apparatus installed in a bathroom of a unit bath in which a wall panel is erected inside a housing, and a lid structure used in the method. It is.

例えば、集合住宅住戸内のユニットバスは、住戸内の所定場所に設置した床パンの縁部に壁パネルを立設して浴室を形成し、この浴室内の洗い場に隣接して浴槽が設置され、且つ、浴槽の洗い場側側面は、見栄えを良くするため、或は、洗い場側から浴槽の下面に水が入らないようにするため、エプロンにより覆われた構造となっている。又、例えば、浴室外において、浴室を挟んで脱衣所の反対側で躯体壁外部のシャフト(PS)内に設置した給湯器に接続された給湯配管は、浴室の床パン下部の空間を延在して、隣接する脱衣所の床面下部の空間に延在し、該空間において分岐し、分岐した給湯配管のうちの1本は、浴室の床パン下部の空間を通って浴室の壁パネル裏面の空間を立上り、その先端は、エルボ継手を介して浴室内に設置した湯水混合栓の給湯側に接続されている。又、同様に、浴室外の例えば、前記PS内に敷設した給水主配管に接続された給水配管は、浴室の床パン下部の空間を通って脱衣所の床面下部の空間に延在し、該空間において分岐し、分岐した給水配管のうちの1本は、浴室の床パン下部の空間を通って浴室の壁パネル裏面の空間を立上り、その先端は、エルボ継手を介して浴室内に設置した湯水混合栓の給水側に接続されている。更に、分岐した給湯配管、給水配管のうち、他の給湯配管や給水配管は、夫々洗面器や洗濯機、水洗トイレのタンク、台所の水栓等のほかの機器器具に接続されている。   For example, in a unit bath in a housing complex, a bathroom is formed by standing a wall panel on the edge of a floor pan installed at a predetermined location in the dwelling unit, and a bathtub is installed adjacent to the washing area in the bathroom. In addition, the side surface of the washing room side of the bathtub is covered with an apron in order to improve the appearance or prevent water from entering the lower surface of the bathtub from the washing area side. Also, for example, outside the bathroom, the hot water supply pipe connected to the water heater installed in the shaft (PS) outside the housing wall on the opposite side of the dressing room across the bathroom extends the space below the floor pan of the bathroom Then, it extends to the space below the floor surface of the adjacent dressing room, branches in the space, and one of the branched hot water supply pipes passes through the space below the floor pan of the bathroom and is behind the wall panel of the bathroom. The tip of the space is connected to the hot water supply side of a hot and cold water mixing plug installed in the bathroom via an elbow joint. Similarly, outside the bathroom, for example, the water supply pipe connected to the main water supply pipe laid in the PS extends through the space below the floor pan of the bathroom to the space below the floor of the dressing room, One of the branched water supply pipes branching in the space rises through the space under the floor pan of the bathroom and rises up the space on the back of the bathroom wall panel, and its tip is installed in the bathroom via an elbow joint. It is connected to the water supply side of the water tap. Further, among the branched hot water supply pipes and water supply pipes, other hot water supply pipes and water supply pipes are connected to other equipment such as a wash basin, a washing machine, a flush toilet tank, and a kitchen faucet, respectively.

経年劣化等により躯体壁の内部に壁パネルを立設するユニットバスの浴室内へ供給される給湯配管や給水配管を更新する場合は、壁パネル裏面の空間や床パン下部の空間に設置された給湯配管や給水配管は撤去せず、そのまま残置し、更新された給湯配管や給水配管は浴室内の隅辺部に露出した状態で配置して化粧用配管カバーによって覆うようにしている。   When renewing the hot water supply pipes and water supply pipes supplied to the bathroom of the unit bath where the wall panels are erected inside the frame wall due to deterioration over time, etc., they were installed in the space behind the wall panels and the space below the floor pan. The hot water supply pipes and water supply pipes are not removed but are left as they are, and the updated hot water supply pipes and water supply pipes are arranged in a state of being exposed at the corners in the bathroom and covered with a cosmetic pipe cover.

なお、浴室の給湯、給水用の配管構造の例としては、特許文献1、2があり、浴室の壁パネルに開口を設ける壁構造の例としては、特許文献3、4がある。   In addition, there exist patent documents 1 and 2 as an example of the hot water supply of a bathroom, and the piping structure for water supply, and there exist patent documents 3 and 4 as an example of the wall structure which provides an opening in the wall panel of a bathroom.

特開平9−228434号公報JP-A-9-228434 特開平6−193286号公報JP-A-6-193286 特開平11−62286号公報JP-A-11-62286 特開2004−76563号公報JP 2004-76563 A

しかしながら、従来のユニットバスの給湯配管や給水配管の更新を行なう場合、更新した給湯配管及び給水配管は、化粧用配管カバーで覆っているものの浴室内に露出して設置しているため、見栄えが悪く、又、給湯配管及び給水配管を覆う化粧用配管カバーは白一色しかなかったため、浴室の壁面に色が合わない場合、目障りで不恰好であり、更新後、浴室の清掃の際には給湯配管及び給水配管が邪魔になり、清掃作業がやり難かった。   However, when renewing the hot water supply pipes and water supply pipes of a conventional unit bath, the updated hot water supply pipes and water supply pipes are exposed in the bathroom although they are covered with a cosmetic pipe cover, so it looks nice. It was bad, and the makeup pipe cover covering the hot water supply pipe and the water supply pipe was only white, so if the color does not match the bathroom wall, it is annoying and unpleasant, and after renewal, the hot water supply pipe when cleaning the bathroom Also, the water supply piping was in the way, and cleaning work was difficult.

一方、特許文献1の場合、浴室内に設置された湯水混合栓に接続された給湯配管及び給水配管は、壁パネルと収納部壁面との間の空間内に敷設されているが、特別なカウンター構造が必要であり、又、給湯配管及び給水配管を更新する際の手順については何等開示されてはいない。又、特許文献2の場合、ユニットバスルーム内のユニット側配管は、枝管を介して、ユニットバスルーム内の特別に設けたカウンター外側に配置された躯体壁面間に形成された空間内に敷設されている主配管に接続されているが、主配管を更新する際の手順については何等開示されてはいない。   On the other hand, in the case of Patent Document 1, the hot water supply pipe and the water supply pipe connected to the hot and cold water mixing tap installed in the bathroom are laid in the space between the wall panel and the storage unit wall surface. A structure is required, and no procedure is disclosed for renewing hot water supply pipes and water supply pipes. Further, in the case of Patent Document 2, the unit side pipe in the unit bathroom is laid in a space formed between the wall surfaces of the casing arranged outside the specially provided counter in the unit bathroom via a branch pipe. Although it is connected to the main pipe, no procedure is disclosed for renewing the main pipe.

更に、特許文献3は、ユニットバスルームの壁に開口を形成してその開口部に浴室内部棚用途のニッチパネルを設置しているが、当該開口部は、給湯配管及び給水配管を更新するための開口ではなく、更に又、特許文献4は、壁パネルに開口部を形成してその開口部に給湯器を設置しているが、この開口部は給湯配管及び給水配管を更新するために設けたものではない。   Furthermore, although patent document 3 forms the opening in the wall of a unit bathroom, and installs the niche panel for bathroom inside shelves in the opening part, the opening part is for updating hot water supply piping and water supply piping Furthermore, in Patent Document 4, an opening is formed in the wall panel and a water heater is installed in the opening, but this opening is provided for renewing the hot water supply pipe and the water supply pipe. Not a thing.

本発明は、上記実情に鑑み、給湯配管及び給水配管等の配管を更新する際に、壁パネルに開口を形成して該開口から配管の更新を行い得るようにすることにより、様々な型式のユニットバスシステムの配管更新にも対応できて改造が少なく、且つ更新した配管を浴室内に設置せず壁パネル裏面の空間に設置するようにして見栄えを向上させ、しかも、更新後の清掃時に配管が邪魔にならないようにした配管の更新方法を提供すると共に、給湯配管及び給水配管等の配管の更新後に見栄え良く開口を塞ぐことができるようにした蓋体構造を提供することを目的としてなしたものである。   In view of the above circumstances, the present invention can provide various types of models by forming an opening in a wall panel and updating a pipe from the opening when updating a pipe such as a hot water supply pipe and a water supply pipe. The unit bus system can be renewed with little modification, and the renovated pipes are installed in the space behind the wall panel instead of being installed in the bathroom. The purpose of the present invention is to provide a lid structure that can close the opening nicely after renewal of piping such as hot water supply piping and water supply piping, as well as providing a method for renewing piping that does not interfere with Is.

It is screwed. Further, a mixing plug main body 36 is detachably attached to the leg pipes 34 and 35 provided integrally with the connecting pipes 30 and 31, and the hot and cold mixing plug 15 is attached to the surface of the wall panel 7 on the bathroom 1 side. ing.

図1a、図1bに示す、壁パネル7と建物躯体8との間の空間9から床パン4下部の空間12を経て浴室1の外部まで敷設された給湯配管10及び給水配管11を更新する場合は、浴槽6の洗い場に面した側(例えば、図1aの紙面に対し手前側)に設けられている図示してないエプロンを撤去した後、浴槽6を湯水混合栓15側から離反する側へ移動させて(図3a、図3b参照)、壁パネル7の湯水混合栓15設置部前面に作業用のスペースを形成し、スペースを形成した位置における壁パネル7の斜め下方所定位置に約250mm×250mmの開口40を設ける(図4a、図4b参照)。   When the hot water supply pipe 10 and the water supply pipe 11 laid from the space 9 between the wall panel 7 and the building frame 8 to the outside of the bathroom 1 through the space 12 below the floor pan 4 shown in FIGS. 1a and 1b are updated. After removing the apron (not shown) provided on the side of the bathtub 6 facing the washing area (for example, the front side of the paper of FIG. 1a), the bathtub 6 is moved away from the hot water mixing tap 15 side. Move (see FIGS. 3a and 3b) to form a working space in front of the hot water / water mixing tap 15 installation portion of the wall panel 7, and about 250 mm × at a predetermined position obliquely below the wall panel 7 at the position where the space is formed. A 250 mm opening 40 is provided (see FIGS. 4a and 4b).

壁パネル7に開口40を設けたら、次いで、湯水混合栓15をエルボ継手13,14から取外して壁パネル7から撤去し(湯水混合栓15の取外し方の詳細は後述する)、しかる後、給湯配管10及び給水配管11を開口40の下縁よりも若干下方位置でセーパーソー等の切断工具により切断し、上端にエルボ継手13,14が接続された状態の切断した給湯配管10及び給水配管11の当該エルボ継手13,14を、切断された給湯配管10及び給水配管11と一体のまま小孔24,25から空間9側へ抜取り、切断された給湯配管10及び給水配管11をエルボ継手13,14が取付けられた状態のまま、空間9から開口40を通して浴室1内に取出し、更に浴室1外へ搬出する(図5a、5b参照)。給湯配管10及び給水配管11は、夫々一本ずつ空間9から取出すが、順序としてはどちらを先にしても良い。給湯配管10及び給水配管11の空間9,12に残った部分はそのまま残置しておく(図5a、図5b参照)。   After the opening 40 is provided in the wall panel 7, the hot water mixing plug 15 is then removed from the elbow joints 13 and 14 and removed from the wall panel 7 (details of how to remove the hot water mixing plug 15 will be described later). The pipe 10 and the water supply pipe 11 are cut with a cutting tool such as a saver saw at a position slightly below the lower edge of the opening 40 and the elbow joints 13 and 14 are connected to the upper ends of the cut hot water supply pipe 10 and water supply pipe 11. The elbow joints 13 and 14 are extracted from the small holes 24 and 25 to the space 9 side while being integrated with the cut hot water supply pipe 10 and the water supply pipe 11, and the cut hot water supply pipe 10 and the water supply pipe 11 are removed from the elbow joints 13 and 14. Is attached to the bathroom 1 from the space 9 through the opening 40, and is further carried out of the bathroom 1 (see FIGS. 5a and 5b). The hot water supply pipe 10 and the water supply pipe 11 are taken out from the space 9 one by one, but either may be put in order. The portions remaining in the spaces 9 and 12 of the hot water supply pipe 10 and the water supply pipe 11 are left as they are (see FIGS. 5a and 5b).

湯水混合栓15を壁パネル7から撤去する手順は以下のとおりである。すなわち、図2において、袋ナット37,38を緩めて混合栓本体36を脚管34,35から撤去し、接続管30,31と一体の脚管34,35を、夫々、接続管30,31と共に回動させることにより、エルボ継手13,14の水平部16,17先端から接続管30,31と共に離脱させ、化粧カバー32,33と一緒に撤去する。次いで、固定リング26,27をエルボ継手13,14における水平部16,17先端部の雄ねじ18,19から除去し、Oリング28,29も除去する。而して、これで湯水混合栓15の取外しは終了したため、給湯配管10及び給水配管11を切断すれば、切断された給湯配管10及び給水配管11は前述のように、空間9から開口40を通して浴室1内へ取出すことができる。   The procedure for removing the hot / cold mixing tap 15 from the wall panel 7 is as follows. That is, in FIG. 2, the cap nuts 37, 38 are loosened to remove the mixing plug body 36 from the leg tubes 34, 35, and the leg tubes 34, 35 integrated with the connection tubes 30, 31 are connected to the connection tubes 30, 31 respectively. By rotating together, the horizontal pipes 16 and 17 of the elbow joints 13 and 14 are detached from the tips of the horizontal parts 16 and 17 together with the connecting pipes 30 and 31 and removed together with the decorative covers 32 and 33. Next, the fixing rings 26 and 27 are removed from the male threads 18 and 19 at the tips of the horizontal portions 16 and 17 of the elbow joints 13 and 14, and the O-rings 28 and 29 are also removed. Thus, since the removal of the hot and cold water mixing tap 15 is completed, if the hot water supply pipe 10 and the water supply pipe 11 are cut, the cut hot water supply pipe 10 and the water supply pipe 11 pass through the opening 40 from the space 9 as described above. It can be taken out into the bathroom 1.

切断した給湯配管10及び給水配管11を空間9から撤去したら、一端部に新たなエルボ継手13,14が連結された長さ約3m〜4mの可撓性の給湯配管41及び給水配管42を、エルボ継手13,14が設けられていない先端側から開口40に挿入し、空間9,12を経て浴室1に隣接した脱衣所の床面下部の空間まで順次送り込む(図6a、図6b参照)。通常は室内面を水洗浄しないため、防水性を厳密に要求されない脱衣所の側では施工上よくあるが、今回も床に開口を設けておき、この開口から給湯配管41及び給水配管42を引くようにする。給湯配管41及び給水配管42は、例えば、内管と、内管より硬い外管を有する架橋ポリエチレン製の二層管で、望ましくは外周を緩衝材で被覆した可撓性管である。このような架橋ポリエチレン製の可撓性管を用いるのは、給湯配管41及び給水配管42を空間9,12に敷設する際に、給湯配管41,給水配管42の接液する内管が、建物躯体8や床スラブ2、基礎3等に擦れて損傷するのを防止するためであり、緩衝材は可撓性管の外周の保護と、更新後の運転中にウォータハンマにより振動して他のものにぶつかった場合の音を緩衝するためである。図6a、図6bでは、一本の管を図示しているが、実際は、例えば、最初に給湯配管41を敷設し、次いで給水配管42を敷設する。又、最初に給水配管42を敷設し、次いで給湯配管41を敷設しても良い。   When the cut hot water supply pipe 10 and the water supply pipe 11 are removed from the space 9, a flexible hot water supply pipe 41 and a water supply pipe 42 having a length of about 3 m to 4 m, each having a new elbow joint 13, 14 connected to one end, The elbow joints 13 and 14 are inserted into the opening 40 from the tip side where the elbow joints 13 and 14 are not provided, and are sequentially fed through the spaces 9 and 12 to the space below the floor of the dressing room adjacent to the bathroom 1 (see FIGS. 6a and 6b). Normally, the interior surface is not washed with water, so it is often done on the side of a dressing room where waterproofness is not strictly required. However, an opening is provided in the floor again, and the hot water supply pipe 41 and the water supply pipe 42 are drawn from this opening. Like that. The hot water supply pipe 41 and the water supply pipe 42 are, for example, a double-layered polyethylene pipe having an inner pipe and an outer pipe harder than the inner pipe, and preferably a flexible pipe whose outer periphery is covered with a buffer material. Such a flexible pipe made of polyethylene is used because when the hot water supply pipe 41 and the water supply pipe 42 are laid in the spaces 9 and 12, the inner pipe in contact with the hot water supply pipe 41 and the water supply pipe 42 is the building. This is to prevent the casing 8, floor slab 2, foundation 3 and the like from being rubbed and damaged. The cushioning material protects the outer periphery of the flexible tube and is vibrated by a water hammer during the operation after renewal. This is to buffer the sound when hitting something. 6a and 6b show one pipe, in practice, for example, the hot water supply pipe 41 is first laid and then the water supply pipe 42 is laid. Alternatively, the water supply pipe 42 may be laid first, and then the hot water supply pipe 41 may be laid.

給湯配管41及び給水配管42が空間9から空間12を経て脱衣所の床面下部の空間所定位置まで敷設されたら、例えば、給湯配管41及び給水配管42の上端に連結されたエルボ継手13,14の水平部16,17先端を、図2に示すように壁パネル7の小孔24,25に嵌入し、次いで、予めOリング26,27が設けられている固定リング26,27を水平部16,17の雄ねじ20,21に螺合し、エルボ継手13,14をフランジ22,23と固定リング26,27により壁パネル7に対し固定する。又、エルボ継手13,14の壁パネル7に対する固定が終了したら、脚管34,35と一体で且つ外周に化粧カバー32,33が嵌められた接続管30,31をエルボ継手13,14における水平部16,17の先端側内周に形成した雌ねじ20,21に螺合し、次いで、脚管34,35に混合栓本体36を接続して袋ナット37,38を締め、混合栓本体36を脚管34,35に対し固定する。更に、給湯配管41及び給水配管42の空間9内に位置する部分には、開口40から上下方向に所定の間隔で複数の固定ブラケット43,44を取付け、固定ブラケット43,44を介して給湯配管41及び給水配管42を建物躯体8の内側に固定し、開口40を蓋体45により閉塞する(図7a、図7b、図8(a)参照)。   When the hot water supply pipe 41 and the water supply pipe 42 are laid from the space 9 through the space 12 to a predetermined position in the space below the floor of the dressing room, for example, elbow joints 13 and 14 connected to the upper ends of the hot water supply pipe 41 and the water supply pipe 42. The ends of the horizontal portions 16 and 17 are inserted into the small holes 24 and 25 of the wall panel 7 as shown in FIG. 2, and then the fixing rings 26 and 27 on which the O-rings 26 and 27 are provided in advance are attached to the horizontal portion 16. 17 and 17 are fixed to the wall panel 7 by flanges 22 and 23 and fixing rings 26 and 27. When the elbow joints 13 and 14 are fixed to the wall panel 7, the connecting pipes 30 and 31, which are integral with the leg pipes 34 and 35 and are fitted with the decorative covers 32 and 33 on the outer periphery, are connected to the elbow joints 13 and 14. Threaded into the female threads 20 and 21 formed on the inner periphery of the distal end side of the portions 16 and 17, and then the mixing plug body 36 is connected to the leg pipes 34 and 35, the cap nuts 37 and 38 are tightened, and the mixing plug body 36 is Fix to the leg tubes 34 and 35. Furthermore, a plurality of fixing brackets 43 and 44 are attached to the portion of the hot water supply pipe 41 and the water supply pipe 42 located in the space 9 at predetermined intervals from the opening 40 in the vertical direction, and the hot water supply pipes are connected via the fixed brackets 43 and 44. 41 and the water supply pipe 42 are fixed inside the building housing 8, and the opening 40 is closed by a lid 45 (see FIGS. 7 a, 7 b, and 8 a).

蓋体45の詳細は、図7b、図8(a)、図8(b)、図8(c)に示されている。すなわち、蓋体45は、開口40に嵌合するステンレス製の矩形額縁状の枠体46と、枠体46に取付けられるステンレス製の板体47とを備えており、枠体46は開口40に直接内嵌する矩形状の内枠46aと、該内枠46aに連なると共に、壁パネル7の浴室1内部側に位置するようにしたフランジ部46bから形成されて断面形状が略アングル型に形成されている。又、内枠46aの四辺には、一辺当り2個ずつの矩形状の小孔48が設けられている。図中、49は、凸形状のばね本体49aと、ばね本体49aの開口側端部両側に一体的に形成された平板状の縁部49bとにより形成された断面Ω形状の内枠固定ばね、50,51は防水用の中空矩形状のラバーテープ、52はコーキング、53は蓋体45固定用のビスである。   Details of the lid 45 are shown in FIGS. 7b, 8a, 8b, and 8c. That is, the lid body 45 includes a stainless frame body 46 made of a rectangular frame that fits into the opening 40 and a stainless steel plate body 47 that is attached to the frame body 46. A rectangular inner frame 46a that directly fits inside, and a flange portion 46b that is connected to the inner frame 46a and is located on the inside of the bathroom 1 of the wall panel 7 and has a substantially angled cross section. ing. Further, two rectangular small holes 48 are provided on each side of the inner frame 46a. In the figure, 49 is an inner frame fixing spring having a cross-sectional Ω shape formed by a convex spring body 49a and flat edge portions 49b integrally formed on both sides of the opening side end of the spring body 49a. 50 and 51 are waterproof rectangular rubber tapes for waterproofing, 52 is caulking, and 53 is a screw for fixing the lid 45.

而して、開口40を蓋体45で閉塞する際には、ラバーテープ50を内枠46aに外嵌させた状態で内枠46aを開口40に貫通させると共に、壁パネル7の浴室側とフランジ部46bとの間にラバーテープ50を挟んだ状態で、枠体46を開口40に嵌合し、しかる後、ばね本体49aを板厚方向へつぶすよう撓ませた内枠固定ばね49を縁部49b側から小孔48に嵌めて内枠固定ばね49を内枠46aに取付ける。そうすると、内枠固定ばね49のばね本体49aが弾撥力によりもとの形状に復帰しようとして、突出部の一側部が壁パネル7の空間9側の面に当接する。このため、枠体46は、ばね本体49aの弾撥力により、ラバーテープ50を挟んで壁パネル7に対し固定される。   Thus, when the opening 40 is closed with the lid body 45, the inner frame 46a is passed through the opening 40 in a state in which the rubber tape 50 is externally fitted to the inner frame 46a. The frame body 46 is fitted into the opening 40 with the rubber tape 50 sandwiched between the portion 46b and then the inner frame fixing spring 49 bent so as to crush the spring body 49a in the plate thickness direction. The inner frame fixing spring 49 is attached to the inner frame 46a by fitting into the small hole 48 from the 49b side. Then, the spring main body 49a of the inner frame fixing spring 49 tries to return to the original shape by elastic force, and one side portion of the projecting portion comes into contact with the surface of the wall panel 7 on the space 9 side. For this reason, the frame 46 is fixed to the wall panel 7 with the rubber tape 50 interposed therebetween by the elastic force of the spring body 49a.
