Description

この発明は、配水管等の管部材を保持する管部材保持具およびこの管部材保持具を用いた管部材配置構造に関する。 The present invention relates to a pipe member holder for holding a pipe member such as a water pipe and a pipe member arrangement structure using the pipe member holder.

特許文献１には、配水管等が挿通される鞘管を、水平位置から垂直状態に立ち上げるために用いられる鞘管サポート具が開示されている。 Patent Document 1 discloses a sheath pipe support tool used for raising a sheath pipe through which a water distribution pipe or the like is inserted from a horizontal position to a vertical state.

特開２０１７−８７５６３号公報JP-A-2017-87563

しかしながら、上記特許文献１の鞘管サポート具は、床側から上方向に曲がる本体部にセットされた鞘管を保持する保持扉を備えるため、構造が複雑になる欠点がある。また、上記鞘管サポート具は予め脚部が床に固定されて鞘管が保持された後に上記鞘管に配管を通すため、配管の作業性に劣るという欠点もある。 However, the sheath tube support tool of Patent Document 1 has a drawback that the structure becomes complicated because it includes a holding door for holding the sheath tube set in the main body portion that bends upward from the floor side. Further, the sheath pipe support tool has a drawback that the workability of the pipe is inferior because the leg portion is fixed to the floor in advance and the sheath pipe is held and then the pipe is passed through the sheath pipe.

この発明は、管部材の曲げ状態を簡単な構造で保持することができる管部材保持具およびこの管部材保持具を用いた管部材配置構造を提供する。 The present invention provides a pipe member holder capable of holding a bent state of a pipe member with a simple structure, and a pipe member arrangement structure using the pipe member holder.

この発明の管部材保持具は、上記の課題を解決するために、管部材が曲げられて収容される管部材収容部と、上記管部材収容部の全体に渡り、上記管部材の曲げ方向を含む面に対して交差する方向に開口する管部材入口部と、を備えることを特徴とする。 In order to solve the above-mentioned problems, the tube member holder of the present invention covers the tube member accommodating portion in which the tube member is bent and accommodated, and the entire tube member accommodating portion, and determines the bending direction of the tube member. It is characterized by including a pipe member inlet portion that opens in a direction intersecting the including surface.

上記の構成であれば、上記管部材収容部内に入れられた管部材が、当該管部材収容部内で元の形状に戻ろうとしても、この戻りの方向には、上記管部材入口部は位置しないので、上記管部材の曲げ状態が保持されることになる。したがって、従来の保持扉のような機構を特別に設けなくても、上記管部材が当該管部材保持具から外れるのを抑制できる。また、上記管部材入口部は、上記管部材収容部の全体に渡って形成されるので、上記管部材の両端が他の配管部材に接続されている状態であっても、当該管部材を上記管部材入口部から上記管部材収容部内に入れることができる。 With the above configuration, even if the pipe member inserted in the pipe member accommodating portion tries to return to the original shape in the pipe member accommodating portion, the pipe member inlet portion is not located in the returning direction. Therefore, the bent state of the pipe member is maintained. Therefore, it is possible to prevent the pipe member from coming off from the pipe member holder without specially providing a mechanism such as a conventional holding door. Further, since the pipe member inlet portion is formed over the entire pipe member accommodating portion, the pipe member can be connected to the other pipe member even when both ends of the pipe member are connected to the other pipe member. It can be put into the pipe member accommodating part from the pipe member inlet part.

上記管部材保持具は、保持対象とする管部材の外径よりも狭い間隔を形成する管部材当たり部を、上記管部材入口部の周囲に備えてもよい。これによれば、上記管部材収容部内の管部材が上記管部材入口部から出ようとしても、この管部材は、上記管部材当たり部に当たるので、上記管部材収容部から外れ難くなる。 The pipe member holder may be provided with a pipe member contact portion that forms a gap narrower than the outer diameter of the pipe member to be held around the pipe member inlet portion. According to this, even if the pipe member in the pipe member accommodating portion tries to come out from the pipe member inlet portion, the pipe member hits the pipe member contact portion, so that it is difficult to be removed from the pipe member accommodating portion.

上記管部材当たり部は、上記管部材入口部の周囲縁から突出させた部位を上記管部材収容部側に折り返して形成されてもよい。これにより、上記管部材当たり部の形成が容易になる。 The pipe member contact portion may be formed by folding back a portion of the portion protruding from the peripheral edge of the pipe member inlet portion toward the pipe member accommodating portion. This facilitates the formation of the pipe member contact portion.

また、上記管部材保持具は、上記のいずれかの管部材保持具が複数本、管部材の曲げ方向および保持範囲を互いに同じにして上記管部材入口部以外の箇所で互いに固定されてもよい。これによれば、複数本の管部材を隣り合わせに並列させて配置する作業が容易になる。 Further, the pipe member holder may be fixed to each other at a place other than the pipe member inlet portion by having a plurality of the pipe member holders, the bending direction and the holding range of the pipe members being the same as each other. .. This facilitates the work of arranging a plurality of pipe members side by side in parallel.

また、上記管部材保持具は、保持対象とする管部材の最小曲げ半径以上で当該最小曲げ半径の１０％〜２０％を当該最小曲げ半径に加算した値を越えない範囲で上記管部材を曲げて保持してもよい。これによれば、管部材の座屈を防止しつつ、狭い場所において管部材を曲げ配置することができる。 Further, the pipe member holder bends the pipe member within a range not exceeding the minimum bending radius of the pipe member to be held and 10% to 20% of the minimum bending radius added to the minimum bending radius. May be held. According to this, the pipe member can be bent and arranged in a narrow place while preventing buckling of the pipe member.

また、この発明の管部材配置構造は、建物の床部材に鉛直方向に形成された連通孔部に管部材が通される管部材配置構造であって、上記床部材の上側および下側の少なくとも一方の側で、上記のいずれかの管部材保持具が用いられ、上記管部材が上記連通孔部に通されることを特徴とする。これによれば、上記床部材の上側および下側の少なくとも一方の側で、上記管部材が上記管部材保持具で保持されるので、上記管部材を上記連通孔部内において略鉛直に保持することが容易になる。 Further, the pipe member arrangement structure of the present invention is a pipe member arrangement structure in which the pipe member is passed through a communication hole formed in the floor member of the building in the vertical direction, and is at least above and below the floor member. One of the above pipe member holders is used on one side, and the pipe member is passed through the communication hole portion. According to this, since the pipe member is held by the pipe member holder on at least one of the upper side and the lower side of the floor member, the pipe member is held substantially vertically in the communication hole portion. Becomes easier.

本発明であれば、従来のような保持扉を必要とせずに、曲げられた管部材の曲げ状態を簡単に保持することができる。また、上記管部材の両端が配管接続された後でも、当該管部材を上記管部材入口部から上記管部材収容部内に入れることができるので、配管の作業性が向上する。 According to the present invention, the bent state of the bent pipe member can be easily held without the need for the conventional holding door. Further, even after both ends of the pipe member are connected to the pipe, the pipe member can be inserted into the pipe member accommodating portion from the pipe member inlet portion, so that the workability of the pipe is improved.

以下、この発明の一態様に係る実施形態を添付図面に基づいて説明する。図１（Ａ）および図１（Ｂ）に示すように、この実施形態の管部材保持具１は、例えば、アルミニウム等の金属、或いはポリ塩化ビニル等の樹脂によって形成されている。また、上記管部材保持具１は、外形が略９０度の円弧形状をなしており、管部材５の保持範囲が９０度の曲げの範囲とされている。また、上記管部材保持具１の延設方向に直交する面による断面形状は、略Ｕ字状となっている。 Hereinafter, embodiments according to one aspect of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1A and 1B, the tube member holder 1 of this embodiment is formed of, for example, a metal such as aluminum or a resin such as polyvinyl chloride. Further, the pipe member holder 1 has an arc shape having an outer shape of approximately 90 degrees, and the holding range of the pipe member 5 is a bending range of 90 degrees. Further, the cross-sectional shape of the pipe member holder 1 by a plane orthogonal to the extending direction is substantially U-shaped.

上記管部材保持具１は、上記略Ｕ字状の断面形状の湾曲部側において形成される管部材収容部１０を備えている。この管部材収容部１０に上記管部材５が曲げられて収容される。 The pipe member holder 1 includes a pipe member accommodating portion 10 formed on the curved portion side of the substantially U-shaped cross-sectional shape. The pipe member 5 is bent and housed in the pipe member accommodating portion 10.

上記管部材５としては、例えば、ポリブテン管或いは架橋ポリエチレン管などの樹脂管が用いられる。このような管部材５は、比較的硬いものの、手の力で曲げることが可能である。 As the pipe member 5, for example, a resin pipe such as a polybutene pipe or a cross-linked polyethylene pipe is used. Although such a pipe member 5 is relatively hard, it can be bent by the force of a hand.

また、上記管部材保持具１は、上記略Ｕ字状の断面形状の開放側に、上記管部材５が入る管部材入口部１１を備えている。この管部材入口部１１は、上記管部材収容部１０の全体に渡り、上記管部材５の曲げ方向を含む面に対して直交する方向に開口している。なお、上記の直交方向に限らず、交差方向としてもよい。この交差方向とする場合、上記管部材５に対する上記管部材保持具１の保持機能および上記管部材５を上記管部材保持具１に入れる際の作業性に支障のない範囲で、上記管部材入口部１１の開口を、上記管部材５の曲げ方向を含む面に対して交差させる。 Further, the pipe member holder 1 is provided with a pipe member inlet portion 11 into which the pipe member 5 is inserted on the open side of the substantially U-shaped cross-sectional shape. The pipe member inlet portion 11 is opened over the entire pipe member accommodating portion 10 in a direction orthogonal to the surface including the bending direction of the pipe member 5. The direction is not limited to the above-mentioned orthogonal direction, and may be an intersecting direction. In the case of this crossing direction, the pipe member inlet does not interfere with the holding function of the pipe member holder 1 with respect to the pipe member 5 and the workability when the pipe member 5 is put into the pipe member holder 1. The opening of the portion 11 is crossed with respect to the surface including the bending direction of the pipe member 5.

また、上記管部材保持具１は、保持対象とする管部材５の外径よりも狭い間隔を形成する管部材当たり部１２を、上記管部材入口部１１の周囲に備えている。この実施形態では、当該管部材保持具１の両端と中央側の３箇所の各々において、２つの管部材当たり部１２が対向配置されて、上記管部材入口部１１の幅を部分的に狭めている。また、上記管部材当たり部１２は、上記管部材入口部１１の周囲縁から突出させた突出部位を、上記管部材収容部１０側に折り返して形成されている。上記突出部位は、上記管部材収容部１０の肉厚と同じ肉厚を有しており、上記折り返しによって形成される上記管部材当たり部１２は、上記肉厚の２倍の肉厚を有することになる。また、上記折り返された上記突出部位の先端は、上記管部材収容部１０側に向いており、上記管部材収容部１０内に収容された管部材５の周面に近接して位置する。また、上記管部材当たり部１２は、管部材保持具１の素材と同じ素材で形成することができるが、同じ素材に限定されるものではない。 Further, the pipe member holder 1 is provided with a pipe member contact portion 12 forming a gap narrower than the outer diameter of the pipe member 5 to be held around the pipe member inlet portion 11. In this embodiment, two pipe member contact portions 12 are arranged to face each other at both ends of the pipe member holder 1 and at each of the three locations on the center side, so that the width of the pipe member inlet portion 11 is partially narrowed. There is. Further, the pipe member contact portion 12 is formed by folding back a protruding portion protruding from the peripheral edge of the pipe member inlet portion 11 toward the pipe member accommodating portion 10. The protruding portion has the same wall thickness as the pipe member accommodating portion 10, and the pipe member contact portion 12 formed by the folding back has a wall thickness twice the wall thickness. become. Further, the tip of the folded protruding portion faces the pipe member accommodating portion 10 side, and is located close to the peripheral surface of the pipe member 5 accommodated in the pipe member accommodating portion 10. Further, the pipe member contact portion 12 can be formed of the same material as the material of the pipe member holder 1, but is not limited to the same material.

上記管部材５の外径は、管自体の外径に限らず、例えば、断熱材等が被覆された状態の当該断熱材等を含めた外径とすることもできる。また、上記管部材入口部１１の幅および上記管部材当たり部１２の幅は、上記管部材５の入れ易さと外れ難さの兼ね合いで決定することができる。 The outer diameter of the pipe member 5 is not limited to the outer diameter of the pipe itself, and may be, for example, the outer diameter including the heat insulating material or the like covered with the heat insulating material or the like. Further, the width of the pipe member inlet portion 11 and the width of the pipe member contact portion 12 can be determined in consideration of the ease of inserting and the difficulty of detaching the pipe member 5.

また、この実施形態では、上記管部材保持具１は、保持対象とする管部材５の最小曲げ半径以上で当該最小曲げ半径の１０％〜２０％（１０％以上２０％以下）を当該最小曲げ半径に加算した値を越えない範囲で上記管部材を曲げて保持する。上記管部材５の最小曲げ半径は、例えば、管部材のメーカー等によって、当該管部材５の呼び径に対して規定されている。 Further, in this embodiment, the pipe member holder 1 bends 10% to 20% (10% or more and 20% or less) of the minimum bending radius of the pipe member 5 to be held at the minimum bending radius or more. The pipe member is bent and held within a range not exceeding the value added to the radius. The minimum bending radius of the pipe member 5 is defined by, for example, the manufacturer of the pipe member or the like with respect to the nominal diameter of the pipe member 5.

上記の構成であれば、上記管部材収容部１０内に入れられた管部材５が、当該管部材収容部１０内で元の形状に戻ろうとしても、この戻りの方向には、上記管部材入口部１１は位置しないので、上記管部材５の曲げ状態が保持されることになる。したがって、従来の保持扉のような機構を特別に設けなくても、上記管部材５が当該管部材保持具１から外れるのを抑制できる。また、上記管部材入口部１１は、上記管部材収容部１０の全体に渡って形成されるので、上記管部材５の両端が配管接続された後でも、当該管部材５を上記管部材入口部１１から上記管部材収容部１０内に入れることができる。 With the above configuration, even if the pipe member 5 inserted in the pipe member accommodating portion 10 tries to return to the original shape in the pipe member accommodating portion 10, the pipe member is in the returning direction. Since the inlet portion 11 is not located, the bent state of the pipe member 5 is maintained. Therefore, it is possible to prevent the pipe member 5 from coming off from the pipe member holder 1 without specially providing a mechanism such as a conventional holding door. Further, since the pipe member inlet portion 11 is formed over the entire pipe member accommodating portion 10, the pipe member 5 is connected to the pipe member inlet portion even after both ends of the pipe member 5 are connected by piping. It can be put into the pipe member accommodating portion 10 from 11.

また、上記管部材保持具１において、保持対象とする管部材５の外径よりも狭い間隔を形成する管部材当たり部１２を、上記管部材入口部１１の周囲に備えていると、上記管部材収容部１０内の管部材５が上記管部材入口部１１から出ようとしても、この管部材５は、上記管部材当たり部１２に当たるので、上記管部材収容部１０から外れ難くなる。 Further, in the pipe member holder 1, if the pipe member contact portion 12 forming a gap narrower than the outer diameter of the pipe member 5 to be held is provided around the pipe member inlet portion 11, the pipe is provided. Even if the pipe member 5 in the member accommodating portion 10 tries to come out from the pipe member inlet portion 11, the pipe member 5 hits the pipe member contact portion 12, so that it is difficult to be removed from the pipe member accommodating portion 10.

また、上記管部材当たり部１２が、上記管部材入口部１１の周囲縁から突出する部位を上記管部材収容部１０側に折り返して形成されていると、上記管部材当たり部１２の形成が容易になる。 Further, when the pipe member contact portion 12 is formed by folding back a portion protruding from the peripheral edge of the pipe member inlet portion 11 toward the pipe member accommodating portion 10, the pipe member contact portion 12 can be easily formed. become.

また、上記管部材保持具１が、保持対象とする管部材５の最小曲げ半径以上で当該最小曲げ半径の１０％〜２０％を当該最小曲げ半径に加算した値を越えない範囲で上記管部材５を曲げて保持すると、管部材５の座屈を防止しつつ、狭い場所において管部材５を曲げ配置することができる。 Further, the pipe member holder 1 does not exceed the minimum bending radius of the pipe member 5 to be held and 10% to 20% of the minimum bending radius is added to the minimum bending radius. When the pipe member 5 is bent and held, the pipe member 5 can be bent and arranged in a narrow place while preventing the pipe member 5 from buckling.

図２は、上記管部材保持具１を用いた管部材配置構造２の一例を示している。この管部材配置構造２においては、建物の床部材６であるＡＬＣ（autoclaved lightweight aerated concrete）に鉛直方向に形成された連通孔部６１に上記管部材５が通される。そして、上記床部材６の上側および下側において上記管部材保持具１に上記管部材５が装着され、上記連通孔部６１内の管部材５の部分が略鉛直の状態に位置する。すなわち、上側に配置された上記管部材保持具１および下側に配置された上記管部材保持具１は、各々の上記連通孔部６１側の接線が略鉛直方向を向くように配置されており、上記連通孔部６１内を管部材５が略鉛直に通る。上記管部材５は、比較的硬いので、上記略鉛直の状態は上記管部材５の硬さで維持される。なお、上記連通孔部６１内において、上記管部材５の周囲には、耐火材６２が充填される。また、上記床部材６の上方には、床面材６３が設けられている。 FIG. 2 shows an example of the pipe member arrangement structure 2 using the pipe member holder 1. In the pipe member arrangement structure 2, the pipe member 5 is passed through a communication hole 61 formed in the vertical direction in ALC (autoclaved lightweight aerated concrete) which is a floor member 6 of a building. Then, the pipe member 5 is mounted on the pipe member holder 1 on the upper side and the lower side of the floor member 6, and the portion of the pipe member 5 in the communication hole portion 61 is located in a substantially vertical state. That is, the pipe member holder 1 arranged on the upper side and the pipe member holder 1 arranged on the lower side are arranged so that the tangents on the communication hole portion 61 side of each face in the substantially vertical direction. The pipe member 5 passes through the communication hole portion 61 substantially vertically. Since the pipe member 5 is relatively hard, the substantially vertical state is maintained by the hardness of the pipe member 5. In the communication hole portion 61, a refractory material 62 is filled around the pipe member 5. Further, a floor surface material 63 is provided above the floor member 6.

上記管部材配置構造２のように、上記管部材５が、上記管部材保持具１に保持されて、上記連通孔部６１内に通されると、上記管部材５を上記連通孔部６１内に略鉛直に保持する施工が、エルボ継ぎ手等を用いなくても簡単に行えるようになる。また、上記連通孔部６１が大径である場合でも、上記管部材５を上記連通孔部６１内で略鉛直に保持できる。また、上記管部材５がその最小曲げ半径程度で上記管部材保持具１に保持される場合には、床下空間が低くても、上記連通孔部６１内の管部材５の部分が略鉛直の状態に保持することが可能になる。なお、上記床部材６の上側および下側のいずれか一方において、上記管部材保持具１に上記管部材５が保持される構造としてもよい。 When the pipe member 5 is held by the pipe member holder 1 and passed through the communication hole portion 61 as in the pipe member arrangement structure 2, the pipe member 5 is moved into the communication hole portion 61. It will be possible to easily hold the pipe almost vertically without using an elbow joint or the like. Further, even when the communication hole portion 61 has a large diameter, the pipe member 5 can be held substantially vertically in the communication hole portion 61. Further, when the pipe member 5 is held by the pipe member holder 1 with the minimum bending radius thereof, the portion of the pipe member 5 in the communication hole portion 61 is substantially vertical even if the underfloor space is low. It becomes possible to keep it in a state. The pipe member 5 may be held by the pipe member holder 1 on either the upper side or the lower side of the floor member 6.
