Description

本発明は、空調用被覆銅管、水道管、ガス被覆管などの配管を横引き施工するのに好適な配管用結露防止具に関する。 The present invention relates to an anti-condensation device for piping suitable for horizontally drawing piping such as a coated copper tube for air conditioning, a water pipe, and a gas coated tube.

空調用被覆銅管やガス被覆管などの冷媒用被覆銅管には、配管の外側に発泡ポリエチレンや発泡ポリウレタン等の断熱被覆材からなる被覆層を備えている。そして、これらの冷媒用被覆銅管を水平に吊り下げる場合、配管の周囲を支持する配管用吊りバンドが使用される。ところが、被覆層の外側から配管を支持した場合、この配管用吊りバンドが接する部分に配管の荷重が集中し、被覆層が部分的に圧迫され、所謂、圧縮クリープ変形を起こすことが知られている。 Coated copper tubes for refrigerants such as air-conditioning coated copper tubes and gas coated tubes are provided with a coating layer made of a heat insulating coating material such as foamed polyethylene or foamed polyurethane on the outside of the piping. And when hanging these refrigerant | coolant covering copper pipes horizontally, the hanging band for piping which supports the circumference | surroundings of piping is used. However, when the pipe is supported from the outside of the coating layer, it is known that the load of the pipe is concentrated on the portion where the suspension band for piping is in contact, the coating layer is partially compressed, and so-called compression creep deformation occurs. Yes.

圧縮クリープ変形が生じると、所定の厚みに形成された被覆層の一部が減肉し、断熱被覆材の効果が部分的に失われる。このように被覆層の一部が減肉した場合、この減肉部分に結露が生じ、結露が滴下して壁面や床に染み跡をつける問題や、断熱被覆材の保温効果の低下を招く問題など、種々の不都合が生じる。 When compression creep deformation occurs, a part of the coating layer formed to have a predetermined thickness is thinned, and the effect of the heat insulating coating material is partially lost. In this way, when a part of the coating layer is thinned, condensation occurs in the thinned part, and the condensation drops and causes stains on the wall surface and floor, and the problem of reducing the heat insulation effect of the heat insulating coating material Various inconveniences occur.

そこで従来では、このような被覆層の減肉を防止する手段が各種提案されている。特許文献１に記載の管支持補助具によると、冷媒用被覆銅管と配管用吊りバンドとの間に板状の管支持補助具を介し、冷媒用被覆銅管と配管用吊りバンドとの接触面積を広くすることで、冷媒用被覆銅管へ加わる面圧力を減少させて変形を防止するようにしたものである。 Therefore, conventionally, various means for preventing such thinning of the coating layer have been proposed. According to the pipe support auxiliary tool described in Patent Document 1, contact between the refrigerant-coated copper pipe and the pipe suspension band via the plate-like pipe support auxiliary tool between the refrigerant-coated copper pipe and the pipe suspension band. By increasing the area, the surface pressure applied to the refrigerant-coated copper pipe is reduced to prevent deformation.

また、特許文献２、３は、冷媒用被覆銅管と配管用吊りバンドとの間に発泡樹脂製の保温シートを設けたもので、この保温シートで結露やカビの発生、あるいは保温効果の低下など種々の不都合を解消するものである。 In Patent Documents 2 and 3, a heat insulating sheet made of foamed resin is provided between the refrigerant-coated copper pipe and the suspension band for piping. With this heat insulating sheet, condensation or mold is generated, or the heat insulating effect is lowered. This eliminates various inconveniences.

実開平６‐６９５５４号公報Japanese Utility Model Publication No. 6-69554 特開２００４-１９７８７６号公報JP 2004-197876 A 特開２００９−５２６１１号公報JP 2009-52611 A

ところが、特許文献１に記載の如く、冷媒用被覆銅管と配管用吊りバンドとの間に板状の管支持補助具を介し、冷媒用被覆銅管と配管用吊りバンドとの接触面積を広くして被覆層の変形を防止しようとすると、必要な管支持補助具の長さは100〜250mm程度にもなり、杆支持補助具が極めて大きく嵩張るものになる。この結果、運搬性、収納性、作業性に多くの不都合が生じてしまう。 However, as described in Patent Document 1, the contact area between the refrigerant-coated copper pipe and the piping suspension band is widened via a plate-shaped pipe support auxiliary tool between the refrigerant-coated copper pipe and the piping suspension band. In order to prevent the deformation of the coating layer, the necessary length of the tube support aid is about 100 to 250 mm, and the heel support aid is extremely large and bulky. As a result, many inconveniences occur in the transportability, storage performance, and workability.

しかも、管支持補助具が配管に対して傾斜した状態で接触すると、管支持補助具の端部が被覆層に食い込み、この部分に減肉が生じる虞もある。特に、長めの管支持補助具の長手中央部分を１本の配管用吊りバンドにて支持するので、この配管用吊りバンドの位置が中央から僅かにずれた状態でも管支持補助具に傾斜が生じる。そして、傾斜が強くなるほど管支持補助具の端部の減肉も大きくなる傾向にある。したがってこの杆支持補助具では、冷媒用被覆銅管の表面に常に平行に当たるように細心の注意を払う必要がある。 In addition, when the tube support auxiliary tool is in contact with the pipe in an inclined state, the end portion of the pipe support auxiliary tool may bite into the coating layer, and there is a possibility that thinning may occur in this portion. In particular, since the longitudinal central portion of the long pipe support aid is supported by one pipe suspension band, the pipe support aid is inclined even when the position of the pipe suspension band is slightly shifted from the center. . And as the inclination becomes stronger, the thinning of the end of the tube support aid tends to increase. Therefore, in this saddle support auxiliary tool, it is necessary to pay close attention so that it always contacts the surface of the coated copper pipe for refrigerant.

また、特許文献２、３に記載のように冷媒用被覆銅管と配管用吊りバンドとの間に発泡樹脂製の断熱材や保温シートを設け、この保温シートで結露やカビの発生などを防止する手段では、断熱材の変形や保温シートの固定手段に課題が残されていた。 In addition, as described in Patent Documents 2 and 3, a foamed resin heat insulating material and a heat insulating sheet are provided between the refrigerant-coated copper pipe and the piping suspension band, and this heat insulating sheet prevents the formation of condensation and mold. In the means to do, the subject remains in the deformation | transformation of a heat insulating material and the fixing means of a heat retention sheet | seat.

すなわち、特許文献２に記載の支持具は、金属製の吊りバンドの内側に発泡樹脂製の断熱材を接着したもので、断熱材は吊りバンドの幅と同じ幅になっている。そのため、吊りバンドが冷媒用被覆銅管に対して平均に当接した場合には、吊りバンド内側の断熱材も被覆層に対して平均に当たるが、この被覆層に対して吊りバンドが傾いた状態で支持すると、金属製の吊りバンドの一端が断熱材と共に冷媒用被覆銅管に食い込んでしまう虞がある。したがってこの支持具でも、吊りバンドや内側の断熱材が、冷媒用被覆銅管の表面に常に平行に当たるように細心の注意を払う必要がある。 That is, the support described in Patent Document 2 is obtained by bonding a heat insulating material made of foamed resin to the inside of a metal hanging band, and the heat insulating material has the same width as the width of the hanging band. Therefore, when the suspension band comes into contact with the refrigerant-coated copper tube on the average, the insulation inside the suspension band also hits the coating layer on the average, but the suspension band is tilted with respect to this coating layer If it is supported, there is a risk that one end of the metallic suspension band may bite into the refrigerant-coated copper tube together with the heat insulating material. Therefore, even with this support, it is necessary to pay close attention so that the suspension band and the heat insulating material on the inner side always come in parallel with the surface of the coated copper pipe for refrigerant.

一方、特許文献３に記載の結露防止構造は、当出願人が先に提案したもので、吊りバンドの幅よりも広い面積を有する受板材に、発泡樹脂製の保温シートを設けたものである。そのため、吊りバンドや保温シートの傾きなどに注意を払わずに装着できるので、保温シートの装着作業が極めて容易である。しかも、保温シートは吊りバンド部の幅よりも広い面積を有しているので、減肉の抑止効果や断熱効果も優れている。 On the other hand, the anti-condensation structure described in Patent Document 3 was previously proposed by the present applicant, and is provided with a heat insulating sheet made of foamed resin on a receiving plate material having an area wider than the width of the suspension band. . Therefore, since it can be mounted without paying attention to the inclination of the suspension band or the heat insulation sheet, the operation of attaching the heat insulation sheet is extremely easy. And since the heat insulation sheet has an area wider than the width | variety of a hanging band part, the suppression effect and heat insulation effect of a thinning are also excellent.

ところが、受板材に発泡樹脂製の保温シートを張り付ける構造であるから、保温シートが冷媒用被覆銅管の下面を正確に保持する位置に貼り付ける必要があるなど、製造工程が複雑になる不都合があった。しかも、吊りバンドの幅よりも広い面積を有する受板材に、厚みのある発泡樹脂製の保温シートを重ねた構造なので、全体的に大きく嵩張り、運搬性、収納性、作業性にも課題を残していた。 However, since the heat insulating sheet made of foamed resin is attached to the backing plate material, it is necessary to apply the heat insulating sheet to a position that accurately holds the lower surface of the refrigerant-coated copper tube. was there. In addition, the structure is such that a thick foamed resin insulation sheet is stacked on a backing plate that has an area wider than the width of the suspension band, so there is a problem with overall bulkiness, transportability, storage, and workability. I left it.

そこで本発明は上述の課題を解消すべく創出されたもので、減肉の抑止効果や断熱効果を保ちながら、極めて簡単な作業で装着でき、しかも、製造容易で、運搬性や収納性にも優れた配管用結露防止具の提供を目的とする。 Therefore, the present invention was created to solve the above-mentioned problems, and can be mounted by an extremely simple operation while maintaining the effect of suppressing the thinning and the heat insulation effect, and is easy to manufacture, and is easy to transport and store. The purpose is to provide an excellent anti-condensation device for piping.

上述の目的を達成すべく本発明における第１の手段は、外側に被覆層Ｐ１が設けられた配管Ｐを該被覆層Ｐ１ごと支持する支持具Ｑと被覆層Ｐ１との間に装着される配管用結露防止具であって、支持具Ｑの幅よりも広い面積を有する可撓性の基板部２と、該基板部２の片面に設けられた波板部３とで受板１を構成し、該波板部３の筋目４が配管Ｐの長手方向に沿うようにして被覆層Ｐ１に波板部３を当てて装着するものである。 In order to achieve the above-mentioned object, the first means in the present invention is a pipe mounted between the support Q for supporting the pipe P provided with the coating layer P1 on the outside together with the coating layer P1 and the coating layer P1. Condensation prevention device for use, comprising a flexible substrate portion 2 having an area wider than the width of the support member Q, and a corrugated plate portion 3 provided on one side of the substrate portion 2 to constitute a receiving plate 1. The corrugated plate portion 3 is applied to the coating layer P1 so that the lines 4 of the corrugated plate portion 3 are along the longitudinal direction of the pipe P.

第２の手段は、前記受板１において、前記波板部３の筋目４に沿った両端部を前記基板部２側に圧着して封止片５を設け、前記波板部３側に多数本の独立した空気室６を形成し、各空気室６が前記配管Ｐの長手方向に沿った状態で前記被覆層Ｐ１の周側面を囲むように構成したものである。 The second means is that, in the receiving plate 1, both end portions along the line 4 of the corrugated plate portion 3 are pressure-bonded to the substrate portion 2 side to provide sealing pieces 5, and a large number are provided on the corrugated plate portion 3 side. Independent air chambers 6 are formed, and each air chamber 6 surrounds the peripheral side surface of the coating layer P1 in a state along the longitudinal direction of the pipe P.

第３の手段は、前記受板１に前記支持部Ｑ１を係止せしめる係止口７を形成し、該係止口７に前記支持具Ｑの支持部Ｑ１の幅に対応する数種類の係止溝７Ａを形成し、該支持部Ｑ１の各種の幅に対してこれらの係止溝７Ａを適宜選択できるように設けている。 The third means is to form a locking port 7 for locking the support portion Q1 on the receiving plate 1, and to the locking port 7 several types of locking corresponding to the width of the support portion Q1 of the support tool Q. Grooves 7A are formed and provided so that these locking grooves 7A can be appropriately selected for various widths of the support portion Q1.

第４の手段において、前記受板１の前記基板部２表面に保温シート層８を形成したことにある。 In the fourth means, a heat insulating sheet layer 8 is formed on the surface of the substrate portion 2 of the receiving plate 1.

本発明の請求項１によると、外側に被覆層Ｐ１が設けられた配管Ｐを該被覆層Ｐ１ごと支持する支持具Ｑと、該支持具Ｑと被覆層Ｐ１との間に装着される配管用結露防止具であって、支持具Ｑの幅よりも広い面積を有する可撓性の基板部２と、該基板部２の片面に設けられた波板部３とで受板１を構成し、該波板部３の筋目４が配管Ｐの長手方向に沿うようにして被覆層Ｐ１に波板部３を当てて装着するものであるから、極めて簡単な作業で装着できる。 According to the first aspect of the present invention, the support member Q for supporting the pipe P provided with the coating layer P1 on the outside together with the coating layer P1, and the pipe mounted between the support tool Q and the coating layer P1. Condensation prevention tool, comprising a flexible substrate part 2 having an area wider than the width of the support tool Q, and a corrugated plate part 3 provided on one side of the substrate part 2 to constitute a receiving plate 1; Since the corrugated plate portion 3 is attached to the coating layer P1 so that the stripes 4 of the corrugated plate portion 3 are along the longitudinal direction of the pipe P, the corrugated plate portion 3 can be attached by an extremely simple operation.

しかも、受板１は略板状を成した構造でありながら、波板部３によって受板１の全面に減肉の抑止効果や断熱効果を奏する。したがって、発泡樹脂製の保温シートを一部に張り付けた従来の支持具以上の面積で、同様の減肉の抑止効果や断熱効果を保つことができる。この結果、減肉の抑止効果や断熱効果を保ちながら極めて簡単な作業で装着でき、しかも製造容易で運搬性や収納性にも優れた効果を奏するものである。 Moreover, while the receiving plate 1 has a substantially plate-like structure, the corrugated plate portion 3 provides a thinning suppression effect and a heat insulating effect on the entire surface of the receiving plate 1. Therefore, the same thinning suppression effect and heat insulation effect can be maintained in an area larger than that of a conventional support in which a heat insulating sheet made of foamed resin is partially attached. As a result, it can be mounted by an extremely simple operation while maintaining the effect of suppressing the thinning and the heat insulating effect, and also has the effect of being easily manufactured and having excellent transportability and storage properties.

請求項２によると、受板１は、前記波板部３の筋目４に沿った両端部を前記基板部２側に圧着して封止片５を設け、前記波板部３側に多数本の独立した空気室６を形成し、各空気室６が前記配管Ｐの長手方向に沿った状態で前記波板部３が前記被覆層Ｐ１の周側面を囲むように構成したことにより、発泡樹脂製の保温シートを張り付けた構造と同様の減肉の抑止効果や断熱効果を奏する。 According to claim 2, the receiving plate 1 is provided with sealing pieces 5 by crimping both end portions along the line 4 of the corrugated plate portion 3 to the substrate portion 2 side, and a plurality of pieces are provided on the corrugated plate portion 3 side. In which the corrugated plate portion 3 surrounds the peripheral side surface of the coating layer P1 in a state where each air chamber 6 is along the longitudinal direction of the pipe P. It has the same effect of reducing thinning and heat insulation as the structure with a heat insulating sheet attached.

しかも、受板１の端部は、封止片５が被覆層Ｐ１に接触せず、空気室６のみが被覆層Ｐ１に接触することになる。したがって、従来の板状の管支持補助具のように、配管に対して受板１が傾斜した状態で装着しても、受板１の端部が被覆層Ｐ１に食い込む虞がなくなった。この結果、現場施工において天井面に傾斜があっても従来の板状の杆支持補助具のように、被覆層Ｐ１の表面に受板１が平行に当たるように細心の注意を払うといった面倒な作業は必要なくなった。 In addition, at the end of the receiving plate 1, the sealing piece 5 does not contact the coating layer P1, and only the air chamber 6 contacts the coating layer P1. Therefore, even when the receiving plate 1 is mounted in an inclined state with respect to the pipe as in the conventional plate-like tube support auxiliary tool, there is no possibility that the end portion of the receiving plate 1 bites into the coating layer P1. As a result, even if the ceiling surface is inclined in field construction, the troublesome work of paying close attention so that the receiving plate 1 is in parallel with the surface of the coating layer P1 like a conventional plate-shaped saddle support aid. Is no longer needed.

請求項３では、前記受板１に前記支持部Ｑ１を係止せしめる係止口７を形成し、該係止口７に前記支持具Ｑの支持部Ｑ１の幅に対応する数種類の係止溝７Ａを形成し、前記支持部Ｑ１の各種の幅に対してこれらの係止溝７Ａを適宜選択できるように設けたことにより、数種類の支持部Ｑ１の幅に対してこれらの係止溝７Ａを適宜選択することができる。 In Claim 3, the locking plate 7 which locks the said support part Q1 in the said receiving plate 1 is formed, and several types of locking grooves corresponding to the width | variety of the support part Q1 of the said support tool Q are formed in this locking port 7 7A is formed so that these locking grooves 7A can be appropriately selected with respect to various widths of the support portion Q1, so that these locking grooves 7A are formed with respect to the widths of several types of support portions Q1. It can be selected appropriately.

請求項４のように、受板１の前記基板部２表面に保温シート層８を形成したことにより、受板１により高い保温効果を付与することができる。 According to the fourth aspect, by forming the heat insulating sheet layer 8 on the surface of the substrate portion 2 of the receiving plate 1, a higher heat insulating effect can be imparted to the receiving plate 1.

このように、本発明結露防止具によると、断熱被覆材からなる被覆層を備えた冷媒用被覆銅管等を支持する際に、被覆層の部分的な減肉を防止し、この減肉により生じる結露やカビの発生、あるいは保温効果の低下など種々の不都合を解消し、しかも、極めて簡単な作業で装着でき、製造容易で、運搬性や収納性にも優れ、且つ安価に提供できるなどといった有益な種々の効果を奏するものである。 Thus, according to the dew condensation prevention device of the present invention, when supporting a coated copper pipe for refrigerant having a coating layer made of a heat insulating coating material, partial thinning of the coating layer is prevented.

以下、本発明の実施例を説明する。本発明結露防止具は、基板部２と波板部３とで受板１を構成したものである。この受板１は、外側に被覆層Ｐ１が設けられた配管Ｐを該被覆層Ｐ１ごと支持する支持具Ｑと、該支持具Ｑの帯状の支持部Ｑ１と被覆層Ｐ１との間に装着されるものである（図１参照）。図示例では、吊りボルト状の支持具Ｑに帯環状の支持部Ｑ１を設けたもので、この支持部Ｑ１に配管Ｐを吊下げ支持するものである。 Examples of the present invention will be described below. The anti-condensation device of the present invention comprises a receiving plate 1 composed of a substrate portion 2 and a corrugated plate portion 3. The receiving plate 1 is mounted between a support tool Q that supports the pipe P, on which the coating layer P1 is provided on the outside, together with the coating layer P1, and a belt-like support portion Q1 of the support tool Q and the coating layer P1. (See FIG. 1). In the illustrated example, a belt-like support portion Q1 is provided on a suspension bolt-shaped support Q, and a pipe P is suspended and supported by the support portion Q1.

また、図７、図８に示すごとく、配管Ｐを下から支持するタイプの支持具Ｑにも使用可能である。図示例の支持具Ｑは、溝形鋼等の支持杆Ｓ上に装着するもので（図７参照）、支持部Ｑ１内に複数本の配管Ｐを支持できるように構成している（図８参照）。このような支持具Ｑでも支持部Ｑ１と被覆層Ｐ１との間に受板１を配して使用することができる。 Moreover, as shown in FIG. 7, FIG. 8, it can be used also for the support tool Q of the type which supports the piping P from the bottom. The support tool Q in the illustrated example is mounted on a support rod S such as channel steel (see FIG. 7), and is configured to support a plurality of pipes P in the support portion Q1 (FIG. 8). reference). Such a support Q can also be used with the receiving plate 1 disposed between the support portion Q1 and the coating layer P1.

本発明の受板１を構成する基板部２、波板部３は、支持部Ｑ１の幅よりも広い面積を有する可撓性の板体である。図示の受板１は、矩形状に形成されている（図２参照）。 The board | substrate part 2 and the corrugated board part 3 which comprise the receiving plate 1 of this invention are flexible board | plate bodies which have an area wider than the width | variety of the support part Q1. The illustrated receiving plate 1 is formed in a rectangular shape (see FIG. 2).

基板部２は、可撓性の材質にて形成されるもので、支持具Ｑの支持部Ｑ１に接触する部分である（図３参照）。そのため、接触時の変形を防止できる硬性を有するポリエチレン等の合成樹脂材が使用される。図示例の基板部２は、例えば0.6mmの一層の基板部２を示している（図５参照）。また、基板部２の外側面に、例えばアルミシートを融着した保温シート層８を設けることで、基板部２の保温効果を高めることも可能である（図６参照）。 The substrate portion 2 is formed of a flexible material, and is a portion that contacts the support portion Q1 of the support tool Q (see FIG. 3). Therefore, a synthetic resin material such as polyethylene having a hardness that can prevent deformation at the time of contact is used. The substrate portion 2 in the illustrated example is a single-layer substrate portion 2 of 0.6 mm, for example (see FIG. 5). Further, it is possible to enhance the heat retaining effect of the substrate unit 2 by providing the heat retaining sheet layer 8 in which, for example, an aluminum sheet is fused on the outer surface of the substrate unit 2 (see FIG. 6).

波板部３は、基板部２の片面に設けられた波板で、基板部２の片面に接合されて受板１を構成している（図５参照）。波板部３の厚みは、例えば0.4mm程度で、３０cmの波板部３に３２〜４８本の波が形成されたものが被覆層Ｐ１の直径に合わせて使用される。波板部３の材質も基板部２と同様にポリエチレン等の合成樹脂材が使用される。また、波板部３をゴム材等の弾性材にて形成することも可能である。 The corrugated plate portion 3 is a corrugated plate provided on one surface of the substrate portion 2 and is joined to the single surface of the substrate portion 2 to constitute the receiving plate 1 (see FIG. 5). The thickness of the corrugated plate portion 3 is, for example, about 0.4 mm, and a corrugated plate portion 3 of 30 cm formed with 32 to 48 waves is used according to the diameter of the coating layer P1. The corrugated plate portion 3 is also made of a synthetic resin material such as polyethylene in the same manner as the substrate portion 2. Further, the corrugated plate portion 3 can be formed of an elastic material such as a rubber material.

受板１は、支持具Ｑの支持部Ｑ１と配管Ｐの被覆層Ｐ１との間に装着されるもので、被覆層Ｐ１に波板部３を当てて装着するように構成している（図３参照）。図示の受板１は、筋目４に沿った波板部３の両端部を基板部２側に圧着して封止片５を設けている（図４参照）。この封止片５により、波板部３側に多数本の独立した空気室６が形成されている。そして、各空気室６にて配管Ｐの周側面を囲むように受板１を装着する（図３参照）。また、受板１端部の封止片５は、基板部２側に形成されるので、受板１の端部は被覆層Ｐ１から離れて接触しない構成になっている（図４参照）。 The receiving plate 1 is mounted between the support portion Q1 of the support tool Q and the coating layer P1 of the pipe P, and is configured to be mounted by applying the corrugated plate portion 3 to the coating layer P1 (see FIG. 3). The illustrated receiving plate 1 is provided with sealing pieces 5 by crimping both end portions of the corrugated plate portion 3 along the lines 4 to the substrate portion 2 side (see FIG. 4). The sealing piece 5 forms a large number of independent air chambers 6 on the corrugated plate portion 3 side. And the receiving plate 1 is mounted | worn so that the surrounding side surface of the piping P may be enclosed in each air chamber 6 (refer FIG. 3). Moreover, since the sealing piece 5 of the receiving plate 1 end part is formed in the board | substrate part 2 side, it has the structure which the edge part of the receiving plate 1 leaves | separated from the coating layer P1, and does not contact (refer FIG. 4).

図示の受板１に、支持部Ｑ１を係止せしめる係止口７を形成している（図２参照）。この係止口７は、数種類の係止溝７Ａを有するもので、数種類の前記支持部Ｑ１の幅に対応するように係止溝７Ａの幅の寸法を変えている。そして、支持部Ｑ１の各種の幅に対してこれらの係止溝７Ａを適宜選択できるように設けたものである。また、受板１を貫通する切欠孔９を設けてある。この切欠孔９に結束紐等の止め具Ｒを通して受板１のずれを防止することができる（図１参照）。 The illustrated receiving plate 1 is formed with a locking port 7 for locking the support portion Q1 (see FIG. 2). The locking port 7 has several types of locking grooves 7A, and the width dimension of the locking grooves 7A is changed so as to correspond to the widths of several types of the support portions Q1. These locking grooves 7A are provided so as to be appropriately selected for various widths of the support portion Q1. Further, a notch 9 that penetrates the receiving plate 1 is provided. The receiving plate 1 can be prevented from being displaced through the notch hole 9 through a stopper R such as a binding string (see FIG. 1).
