【発明の属する技術分野】
本発明は、可撓管による給水用配管工法において、床下配管から床面へ立ち上げる部分の配管作業を、能率良く行う為の可撓管保持部材に関するものである。
【０００２】
【従来の技術】
従来から戸建て木造建築物は、地面の上にコンクリート製の基礎を造り、その上に土台を設け、さらに柱を建て、梁・桁と呼ばれる横架材を載せていき、この梁の上に根太と呼ばれる部材を取り付け、その上に床板を貼っていく。この建築物において、給水・給湯に用いられる配管としては、可撓性通水管や可撓性通水管を保護するための可撓性保護管等の可撓管が使用される。
【０００３】
従来、この可撓管を配管施工し床上の器具へと接続していく工法として、実開平６−１９６５号公報の第９〜１１図に記載されているような、所定の曲がり半径で湾曲する押え部材（可撓管を挿通する部分）とこの押え部材を躯体床面等に固定する支持部材とで構成されている可撓管保持部材を利用して可撓管を垂直方向に立ち上げていく方法、併せて特開平６−４２６８０号公報に記載されているような継手支持固定具を用いて、継手位置を床高さに合わせて調整し、可撓管と継手を接続、その後床板貼りを行い器具に接続していく方法がある。
【０００４】
この場合、床板貼り後は可撓管保持部材および継手支持固定具が床下にあるため、床上での可撓管の上下調整ができず、器具との位置合わせや継手の取り替え等には、配管をし直さなければならなかった。また、可撓管の先端位置を多様な床高さに合わせるためには、図９のような調整部材（特開平６−４２６８０号の第１図に記載）が必要となっていた。取付方法は、まず、躯体床面９に固定座金１８と支持ボルト１９からなる支持具を固定し、次に固定リング２０の上面が床面と同じ高さになるように調整ナット２１にて調整し、高さ固定後、継手支持固定具を支持具の支持ボルト１９に取り付ける。
【０００５】
ここでいう継手支持固定具は、躯体床面９に固定された固定座金１８と支持ボルト１９及び調整ナット２１からなる支持具によって支持され、外周面に雄ねじ部２４、内周面に雌ねじ部２３が形成された基台２２とこの基台２２の雌ねじ部２３に螺合して上下に動かし、継手２６を保持する調整スリーブ２５と基台２２の雄ねじ部２４に螺合して継手２６を固定する固定リング２０を備えたものである。固定方法は、調整スリーブ２５を基台２２に対して半分程度螺合した状態としておき、調整スリーブ２５内には継手２６を挿入しておく。次に係止爪を設けた止め具２７とビス２８を用いて、基台２２と床下に配管された可撓性保護管を固定接続し、この状態で床板を貼る。
【０００６】
このような従来の可撓管保持部材を利用した場合は、床板貼り後は、床高さに対応させる支持ボルト１９及び調整ナット２１からなる調整部材が床下にあるため、床板厚さの変更等、１０ｍｍ程度の継手２６の高さ調整しかできていないものであった。これは、この構造で高さ調整代を大きくすると、調整スリーブ２５及び基台２２の長さが長くなりすぎるためである。
【０００７】
上記工法とは別に、躯体床面に可撓管を這わせた状態にしておき、床板貼り後、床下に潜って可撓管を立ち上げる方法がある。これはまず、図１３のように躯体床面９に可撓管１を這わせた状態にしておき、床板１１貼りを行う。次に床板１１の下に潜って、図１７のように、可撓管１を床上に立ち上げて継手１２を接続し、そしてこの可撓管１に、パッキン３８を取り付けたフランジ３２を通してタッピンねじ３９にて床板１１に固定し、可撓性保護管３にクランプ１４を取り付け、図１６のようにフランジ３２内に可撓管１を押し下げる。この後にナット３３、ナット３４、リング３５、ブッシュ３６、パッキン３７を取り付け、器具に接続していく方法である。これにより、図１０のように器具位置に合わせて可撓管１を引き上げ、器具２９と接続することも可能である。しかし、この工法では、可撓性通水管２だけでなく、可撓性保護管３も含めた上下調整が必要なため、床下に可撓管を固定できないことより、床板１１貼り後に床下に潜る必要があった。
【０００８】
また、上記問題点への対応として、図１１のように根太３０にパイプ３１を固定し、このパイプ３１に可撓管１を挿通して立ち上げる方法をとることもある。この立ち上げた可撓管１に継手１２を接続した後、図１２のように床板１１を貼れば、可撓管１は既に立ち上がった状態で保持されているため、床下に潜る必要はなく、施工時の可撓管１の上下調整が可能となり、図１８のように継手１２が床板１１から離れている場合でも施工できる。
【０００９】
このように、この工法では、床下に可撓管１を固定する部位がないため、上記のような、施工中の可撓管１の上下調整が可能である。また、床上で上下調整ができることで、器具取り付け前に、作業しやすい高さにて、図１４のように可撓性通水管２に継手１２を取り付け後、継手１２に塞ぎ蓋４０を取り付け、外れないように継手１２と塞ぎ蓋４０をファスナー４１で固定した状態で耐圧検査を行い、継手１２と可撓性通水管２の接続部、及び塞ぎ蓋４０で塞いだ部分からの漏水確認を行い、その後器具位置に可撓管１を調整することができる。

【発明が解決しようとする課題】
しかしながら上記工法においては、次のような課題を有している。
根太３０等の建築骨組みが可撓管１立ち上げ位置から離れている場合は、図１５のように当て木４２等を取り付ける補助工事が必要となり、材料費・施工費がかさむと共に、配管工事は配管工、当て木工事は大工と作業職種が異なり、配管作業をスムーズに行うには、異なる職種の業者の調整が必要となっていた。
【００１２】
根太３０がなく、可撓管保持部材も利用しない場合は、床板１１を貼るまでは、図１３のように躯体床面９に可撓管１を這わせた状態となるため、床板１１貼りなどの作業時に、可撓管１を踏みつけて傷を付けてしまい、漏水を引き起こす可能性がある。また、床板１１貼り後に床下に潜り、床穴へ可撓管１を立ち上げていかなければならず、床高さが低い場合は、床下に潜れず配管作業ができなくなる場合がある。
【００１３】
そこで、本発明では上記の問題点を解決するため、床下配管から床面へ立ち上げる部分の配管作業を能率良く行うことができ、しかもコストを廉価化することができる可撓管保持部材を提供するものである。
【００１４】
【課題を解決するための手段】
請求項１の発明では、躯体床面に固定する固定部と、可撓管を保持し前記床面に対して水平移動のみを規制する可撓管移動規制手段を設けたことを特徴とする可撓管保持部材を提供するものである。
【００１５】
これにより、可撓管保持部材を躯体床面に固定するのみで芯出しもしやすいため、可撓管立ち上げ位置が根太等の建築骨組みから離れている場合や床高さが低く床下に潜れない場合でも、可撓管を挿通し、立ち上げることができる。
【００１６】
請求項２の発明では、可撓管移動規制手段が、上下の高さ調整を可能にしたことを特徴とする請求項１記載の可撓管保持部材を提供するものである。
【００１７】
これにより、多様な床高さの場合においても、可撓管移動規制手段を垂直状態に保持したまま床面に近づけることができるため、立ち上げた可撓管が上方で倒れ、立ち上げ位置がずれるということもない。また、上下の高さ調節を可能にしたことにより、長さの異なる複数の可撓管移動規制手段を用意しなくてもよい。
【００１８】
請求項３の発明では、可撓管移動規制手段が、側面の少なくとも一部を切り欠いた筒形状であることを特徴とする請求項１〜２記載の可撓管保持部材を提供するものである。
【００１９】
これにより、可撓管移動規制手段は市場に多様に存在する筒を加工するだけでよく、また、多様な内径の可撓管保持部材を製作する場合でも全て同様に、側面の少なくとも一部を切欠くだけでよい。
【００２０】
請求項４の発明では、躯体床面に固定する固定部に、可撓管移動規制手段がワンタッチで接続できることを特徴とする請求項１〜３記載の可撓管保持部材を提供するものである。
【００２１】
これにより、固定部と可撓管移動規制手段の接続を、溶接やねじ込み等の複雑な接続なくして行うことができる。また、固定部のみを先に躯体床面に固定しておけば、可撓管移動規制手段は、可撓管の立ち上げ時に、可撓管を挿通すると同時に固定部にワンタッチ接続できる。
【００２２】
【発明の実施の形態】
以下に図面を参照して本発明をより具体的に説明する。
【００２３】
図１は、本発明における実施の形態１の使用状態を示す断面図であり、可撓管１は次に説明する可撓管保持部材により、水平状態から垂直状態に立ち上げられる。
【００２４】
本発明における実施の形態１の可撓管保持部材は、図１のように躯体床面９に固定する固定部５と、可撓管１を保持し前記床面に対しての水平移動を規制する可撓管移動規制手段４とで構成されている。可撓管保持部材の固定部５は断面側面図を図２に、外観上面図を図３に示す。固定部５は図２のように筒形状であり、下部に固定用の鍔部７がある。この鍔部７は固定用穴１５を有しており、躯体床面９にアンカーボルト８を使って固定する。次に、図４のように可撓管移動規制手段４の側面の少なくとも一部を切り欠いた筒形状の切り欠き部分から可撓管１を挿通し、この可撓管１を挿通した状態の可撓管移動規制手段４の固定部５への差し込み部６を固定部５の筒部１０に差し込む。可撓管移動規制手段４を固定部５の筒部１０に差し込むだけで、同時に可撓管１を垂直状態に立ち上げることができる。よって可撓管移動規制手段４の差し込み部６の内径は、差し込み時のがたつきをなくすために、固定部５の筒部１０の内径とほぼ同径としている。そして、可撓管移動規制手段４の上部は、可撓管１を垂直状態に保持するために、可撓管１が外れるような切り欠きを設けていない。こうすることで、作業が行いやすくなり作業者一人で施工ができるが、この固定が複雑な方法の場合、一人の作業者が可撓管１を挿通した可撓管移動規制手段４を保持した状態で、もう一人の作業者が固定作業を行う必要がある。
【００２５】
尚、本発明における実施の形態１にて、躯体床面９に固定する固定部５と可撓管移動規制手段４をワンタッチで接続する形態は、可撓管移動規制手段４の差し込み部６の外径は、固定部５の筒部１０の内径とほぼ同径と記載したが、これだけでなく、図５のように、固定部５の筒部１０の外側に可撓管移動規制手段４をはめるようにしてもよく、他の方法でもワンタッチで接続できれば、同様の効果がある。
【００２６】
その後、図１の支持部材１３（フランジ３２、ナット３３、３４、リング３５、ブッシュ３６、パッキン３７、３８、タッピンねじ３９、クランプ１４から構成される）を取り付ける必要がある。その際には、従来例と同様に、一度、可撓管１を引き上げてから押し下げる必要がある。この可撓管保持部材使用時の可撓管１引き上げ時、押し下げ時の図を図６、図７に示す。このように可撓管移動規制手段４の切り欠き部での可撓管１の曲率が、引き上げ時は大きくなり、押し下げ時は小さくなることにより、上記作業をスムーズに行うことができる。
【００２７】
本発明における実施の形態２として、可撓管保持部材が上下の高さ調整を可能とし、床高さが高い場合でも、床施工高さでの可撓管の位置と可撓管保持部材位置のずれがほとんどなく床面に近づけることができるものを説明する。図８は、可撓管保持部材により保持された可撓管に床板を貼る作業中の図である。図８において、これは多様な床高さに対応できるように、可撓管移動規制手段４上部の外径部に筒形状をした高さ調整手段１６をはめた可撓管保持部材に、実施の形態１と同様に可撓管１を挿通し、垂直方向に立ち上げる。そして床高さに合わせて、可撓管移動規制手段４を軸にこの高さ調整手段１６を上下に動かし、床面位置に近づけ可撓管１を垂直状態に保持しておく。よって、この高さ調整手段１６の内径と可撓管移動規制手段４の外径は、可撓管移動規制手段４を軸に上下に動かさなければならないため、ほぼ同径としている。図８の破線４３は、施工完了時に床板１１底面が位置する線であり、高さ調整手段１６の上面は、この破線４３と同じ高さになるよう調整されている。こうすることにより、図８に示すように、床工事の際に床板１１に事前にあけた穴１７からの位置ずれがなく、床板貼り工事の際、スムーズに施工ができる。
【００２８】
【発明の効果】
以上のように、躯体床面に固定する固定部と、可撓管を保持し前記床面に対して水平移動のみを規制する可撓管移動規制手段を設けたことを特徴とする可撓管保持部材としたので、可撓管保持部材を躯体床面に固定するのみで芯出しもしやすいため、可撓管立ち上げ位置が根太等の建築骨組みから離れている場合や床高さが低く床下に潜れない場合でも、可撓管を挿通し、立ち上げることができるため、施工の手間が省け、配管作業を能率良く行うことができる。
【００２９】
さらに、可撓管移動規制手段が、上下の高さ調整を可能にしたことを特徴とする可撓管保持部材としたので、多様な床高さの場合においても、可撓管移動規制手段を垂直状態に保持したまま床面に近づけることがでるため、立ち上げた可撓管が上方で倒れ、立ち上げ位置がぶれるということもなく、施工が容易になる。また、上下の高さ調節を可能にしたことにより、長さの異なる複数の可撓管移動規制手段を用意しなくてもよいため、製造コストを廉価化することができる。
【００３０】
さらに、可撓管移動規制手段が、側面の少なくとも一部を切り欠いた筒形状であることを特徴とする可撓管保持部材としたので、可撓管移動規制手段は市場に多様に存在する筒を加工するだけでよく、また、多様な内径の可撓管保持部材を製作する場合でも全て同様に、側面の少なくとも一部を切欠くだけでよいため、低コストで実施することができる。
【００３１】
さらに、躯体床面に固定する固定部に、可撓管移動規制手段がワンタッチで接続できることを特徴とする可撓管保持部材としたので、固定部と可撓管移動規制手段の接続を、溶接やねじ込み等の複雑な接続なくして行うことができる。また、固定部のみを先に躯体床面に固定しておけば、可撓管移動規制手段は、可撓管の立ち上げ時に、可撓管を挿通すると同時に固定部にワンタッチ接続でき、施工の手間が省け、配管作業を能率良く行うことができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a flexible tube holding member for efficiently performing a piping operation of a part rising from a floor pipe to a floor surface in a water supply piping method using a flexible pipe.
[0002]
[Prior art]
Traditionally, a detached wooden building has a concrete foundation on the ground, a foundation on which to build a pillar, and a column. Attach a member called, and stick a floorboard on it. In this building, as a pipe used for water supply / hot water supply, a flexible pipe such as a flexible water pipe or a flexible protection pipe for protecting the flexible water pipe is used.
[0003]
Conventionally, as a method of connecting this flexible tube to a pipe on the floor and connecting it to an instrument on the floor, the flexible tube is bent at a predetermined bending radius as described in FIGS. 9 to 11 of Japanese Utility Model Laid-Open No. 6-1965. The flexible tube is vertically raised by using a flexible tube holding member composed of a pressing member (portion through which the flexible tube is inserted) and a supporting member for fixing the pressing member to the floor of the skeleton. The joint position is adjusted to the floor height by using a joint support fixture as described in JP-A-6-42680, and the flexible tube and the joint are connected. There is a way to connect to the instrument.
[0004]
In this case, since the flexible tube holding member and the joint support fixture are below the floor after the floor plate is attached, the flexible tube cannot be adjusted up and down on the floor. I had to do it again. In addition, in order to adjust the distal end position of the flexible tube to various floor heights, an adjusting member as shown in FIG. 9 (described in FIG. 1 of JP-A-6-42680) is required. The mounting method is as follows. First, a support consisting of a fixed washer 18 and a support bolt 19 is fixed to the floor 9 of the skeleton, and then adjusted with the adjustment nut 21 so that the upper surface of the fixing ring 20 is flush with the floor. After fixing the height, the joint support fixture is attached to the support bolt 19 of the support fixture.
[0005]
The joint support fixture here is supported by a support consisting of a fixed washer 18 fixed to the skeleton floor 9, a support bolt 19 and an adjustment nut 21, a male screw part 24 on the outer peripheral surface, and a female screw part 23 on the inner peripheral surface. Is screwed into the base 22 on which the base 22 is formed and the female screw 23 of the base 22 and moved up and down, and is screwed into the adjusting sleeve 25 holding the joint 26 and the male screw 24 of the base 22 to fix the joint 26. The fixing ring 20 is provided. The fixing method is such that the adjusting sleeve 25 is screwed into the base 22 by about half, and the joint 26 is inserted into the adjusting sleeve 25. Next, the base 22 and the flexible protective tube piped under the floor are fixedly connected to each other using a stopper 27 provided with a locking claw and a screw 28, and a floor plate is attached in this state.
[0006]
When such a conventional flexible tube holding member is used, after the floor plate is affixed, the adjustment member including the support bolt 19 and the adjustment nut 21 corresponding to the floor height is under the floor. Only the height of the joint 26 was adjusted to about 10 mm. This is because if the height adjustment allowance is increased in this structure, the lengths of the adjustment sleeve 25 and the base 22 become too long.
[0007]
Apart from the above-mentioned construction method, there is a method in which a flexible tube is laid on the floor of a skeleton, and after sticking to a floor plate, the flexible tube is raised under the floor. First, as shown in FIG. 13, the flexible tube 1 is laid on the skeleton floor 9 and the floor plate 11 is attached. Next, as shown in FIG. 17, the flexible tube 1 is raised on the floor to connect the joint 12, and the flexible tube 1 is connected to the joint 12 through the flange 32 to which the packing 38 is attached. At 39, the flexible tube 1 is fixed to the floor plate 11, the clamp 14 is attached to the flexible protective tube 3, and the flexible tube 1 is pushed down into the flange 32 as shown in FIG. After that, a nut 33, a nut 34, a ring 35, a bush 36, and a packing 37 are attached and connected to a device. Thereby, the flexible tube 1 can be pulled up in accordance with the position of the instrument as shown in FIG. However, in this method, not only the flexible water pipe 2 but also the flexible protection pipe 3 need to be adjusted vertically, so that the flexible pipe cannot be fixed under the floor. Needed.
[0008]
As a solution to the above problem, a method of fixing a pipe 31 to a joist 30 as shown in FIG. After connecting the joint 12 to the raised flexible tube 1 and attaching the floor plate 11 as shown in FIG. 12, since the flexible tube 1 is already held in the raised state, there is no need to dive under the floor. The flexible tube 1 can be adjusted up and down at the time of construction, and can be constructed even when the joint 12 is separated from the floor plate 11 as shown in FIG.
[0009]
As described above, in this method, since there is no portion for fixing the flexible tube 1 under the floor, the vertical adjustment of the flexible tube 1 during construction as described above is possible. In addition, since it can be adjusted up and down on the floor, before mounting the equipment, at a height that is easy to work, after attaching the joint 12 to the flexible water pipe 2 as shown in FIG. A pressure test is performed with the joint 12 and the closing lid 40 fixed with the fastener 41 so as not to come off, and water leakage from the joint between the joint 12 and the flexible water pipe 2 and the portion closed by the closing lid 40 is checked. The flexible tube 1 can then be adjusted to the instrument position.

[Problems to be solved by the invention]
However, the above method has the following problems.
If the architectural frame such as the joist 30 is away from the flexible tube 1 starting position, auxiliary work for attaching the batten 42 or the like is required as shown in FIG. 15, and material and construction costs are increased, and plumbing work is not required. Plumbers and battens are different from carpenters and work occupations, and in order to perform plumbing smoothly, it is necessary to coordinate with contractors of different occupations.
[0012]
When the joist 30 is not provided and the flexible tube holding member is not used, the flexible tube 1 is laid on the skeleton floor surface 9 as shown in FIG. At the time of the operation, there is a possibility that the flexible tube 1 is trampled and damaged, thereby causing water leakage. In addition, the flexible pipe 1 must be lowered under the floor after the floor plate 11 is attached, and the flexible tube 1 must be raised into the floor hole. When the floor height is low, the flexible pipe 1 may not be able to sink under the floor and may not be able to perform the piping work.
[0013]
Therefore, in order to solve the above-mentioned problems, the present invention provides a flexible tube holding member that can efficiently perform piping work of a portion rising from a floor pipe to a floor surface and can reduce the cost. Is what you do.
[0014]
[Means for Solving the Problems]
The invention according to claim 1 is characterized in that a fixing portion for fixing to the floor of the skeleton and a flexible tube movement restricting means for holding the flexible tube and restricting only horizontal movement with respect to the floor are provided. A flexible tube holding member is provided.
[0015]
By this, since the flexible tube holding member can be easily centered only by fixing the flexible tube holding member to the floor of the skeleton, the flexible tube rising position is away from an architectural framework such as a joist, or the floor height is low, and it is difficult to dive under the floor. Even in this case, the flexible tube can be inserted and raised.
[0016]
According to a second aspect of the present invention, there is provided the flexible tube holding member according to the first aspect, wherein the flexible tube movement restricting means is capable of adjusting the vertical height.
[0017]
Thereby, even in the case of various floor heights, since the flexible tube movement restricting means can be brought close to the floor surface while being held in a vertical state, the raised flexible tube falls down and the rising position is lowered. There is no deviation. Further, since the vertical height can be adjusted, it is not necessary to prepare a plurality of flexible tube movement restricting means having different lengths.
[0018]
According to a third aspect of the present invention, there is provided the flexible tube holding member according to the first or second aspect, wherein the flexible tube movement restricting means has a cylindrical shape in which at least a part of a side surface is cut. is there.
[0019]
Thereby, the flexible tube movement restricting means only needs to process the cylinders that are variously present in the market, and even when manufacturing flexible tube holding members having various inner diameters, similarly, at least a part of the side surface is required. You only need to cut out.
[0020]
According to a fourth aspect of the present invention, there is provided a flexible tube holding member according to any one of the first to third aspects, wherein the flexible tube movement restricting means can be connected to the fixing portion fixed to the skeleton floor surface with one touch. .
[0021]
Thereby, the connection between the fixed portion and the flexible tube movement restricting means can be performed without complicated connection such as welding or screwing. Further, if only the fixing portion is fixed to the floor of the skeleton first, the flexible tube movement restricting means can perform one-touch connection to the fixing portion while inserting the flexible tube when the flexible tube is started up.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0023]
FIG. 1 is a sectional view showing a use state of Embodiment 1 of the present invention. The flexible tube 1 is raised from a horizontal state to a vertical state by a flexible tube holding member described below.
[0024]
The flexible tube holding member according to the first embodiment of the present invention includes a fixing portion 5 fixed to a skeleton floor surface 9 as shown in FIG. 1, and holds the flexible tube 1 to restrict horizontal movement with respect to the floor surface. And the flexible tube movement restricting means 4. FIG. 2 is a sectional side view of the fixing portion 5 of the flexible tube holding member, and FIG. The fixing part 5 has a cylindrical shape as shown in FIG. 2, and has a fixing flange 7 at the lower part. The flange 7 has a fixing hole 15 and is fixed to the frame floor 9 using the anchor bolt 8. Next, as shown in FIG. 4, the flexible tube 1 is inserted through a cylindrical cutout portion in which at least a part of the side surface of the flexible tube movement restricting means 4 is cut out. The insertion part 6 of the flexible tube movement restricting means 4 into the fixed part 5 is inserted into the cylindrical part 10 of the fixed part 5. Simply by inserting the flexible tube movement restricting means 4 into the cylindrical portion 10 of the fixed portion 5, the flexible tube 1 can be simultaneously raised in the vertical state. Therefore, the inner diameter of the insertion portion 6 of the flexible tube movement restricting means 4 is substantially the same as the inner diameter of the cylindrical portion 10 of the fixed portion 5 in order to eliminate rattling at the time of insertion. In addition, the upper portion of the flexible tube movement restricting means 4 is not provided with a cutout for holding the flexible tube 1 in a vertical state so that the flexible tube 1 comes off. By doing so, the work becomes easy and the work can be carried out by one worker alone. However, in the case of this complicated fixing method, one worker holds the flexible tube movement restricting means 4 through which the flexible tube 1 is inserted. In this state, another worker needs to perform the fixing work.

In the first embodiment of the present invention, the fixing portion 5 fixed to the skeleton floor surface 9 and the flexible tube movement restricting means 4 are connected by one touch. The outer diameter is described as being substantially the same as the inner diameter of the cylindrical portion 10 of the fixed portion 5, but in addition to this, the flexible tube movement restricting means 4 is provided outside the cylindrical portion 10 of the fixed portion 5 as shown in FIG. The same effect can be obtained if another method can be used to connect with one touch.
[0026]
After that, it is necessary to attach the support member 13 (consisting of the flange 32, the nuts 33 and 34, the ring 35, the bush 36, the packings 37 and 38, the tapping screw 39, and the clamp 14) of FIG. At that time, it is necessary to raise the flexible tube 1 once and then push it down, as in the conventional example. FIGS. 6 and 7 show diagrams when the flexible tube 1 is raised and pressed when the flexible tube holding member is used. As described above, the curvature of the flexible tube 1 at the notch portion of the flexible tube movement restricting means 4 increases when raising and decreases when pressing down, so that the above operation can be performed smoothly.
[0027]
As a second embodiment of the present invention, the flexible tube holding member can adjust the vertical height, and even when the floor height is high, the position of the flexible tube at the floor construction height and the position of the flexible tube holding member What can be approached to the floor surface with almost no displacement will be described. FIG. 8 is a diagram showing a state in which a floor plate is attached to the flexible tube held by the flexible tube holding member. In FIG. 8, this is applied to a flexible tube holding member in which a cylindrical height adjusting means 16 is fitted to the outer diameter portion of the flexible tube movement restricting means 4 so as to be able to cope with various floor heights. In the same manner as in the first embodiment, the flexible tube 1 is inserted and is raised in the vertical direction. Then, the height adjusting means 16 is moved up and down around the flexible tube movement restricting means 4 in accordance with the floor height to approach the floor surface position and keep the flexible tube 1 in a vertical state. Therefore, the inner diameter of the height adjusting means 16 and the outer diameter of the flexible tube movement restricting means 4 are almost the same diameter because the flexible tube movement restricting means 4 must be moved up and down. The broken line 43 in FIG. 8 is a line where the bottom surface of the floor plate 11 is located when the construction is completed, and the upper surface of the height adjusting means 16 is adjusted to have the same height as the broken line 43. By doing so, as shown in FIG. 8, there is no displacement from the hole 17 previously drilled in the floorboard 11 at the time of flooring, and the floorboard can be smoothly constructed at the time of flooring work.

【The invention's effect】
As described above, the flexible tube is provided with the fixing portion fixed to the skeleton floor surface and the flexible tube movement restricting means for holding the flexible tube and restricting only horizontal movement with respect to the floor surface. Since the holding member is used, the flexible tube holding member can be easily centered only by fixing the flexible tube holding member to the floor of the skeleton. Even when it is difficult to dive into the pipe, the flexible pipe can be inserted and started up, so that the labor for construction can be saved and the piping work can be performed efficiently.
[0029]
Furthermore, since the flexible tube movement restricting means is a flexible tube holding member characterized in that the vertical height can be adjusted, the flexible tube movement restricting means can be used even in various floor heights. Since it is possible to approach the floor surface while maintaining the vertical state, the raised flexible tube does not fall down and the raised position is not deviated, thereby facilitating the construction. Further, since the vertical height can be adjusted, it is not necessary to prepare a plurality of flexible tube movement restricting means having different lengths, so that the manufacturing cost can be reduced.
[0030]
Furthermore, since the flexible tube movement restricting means is a flexible tube holding member characterized in that it has a cylindrical shape with at least a part of the side cut away, there are various flexible tube movement restricting means in the market. It is only necessary to process the cylinder, and also in the case of manufacturing flexible tube holding members having various inner diameters, similarly, it is only necessary to cut out at least a part of the side surface, so that it can be implemented at low cost.
[0031]
Furthermore, since the flexible tube holding member is characterized in that the flexible tube movement restricting means can be connected to the fixing portion fixed to the building floor surface with one touch, the connection between the fixing portion and the flexible tube movement restricting device can be welded. It can be performed without complicated connections such as screwing and screwing. In addition, if only the fixing portion is fixed to the floor of the skeleton first, the flexible tube movement restricting means can be connected to the fixing portion at the same time as the flexible tube is inserted when the flexible tube is started up. Labor can be saved and piping work can be performed efficiently.
