ところが、特許文献1の技術は、ヘッダーが床下であるため、普段確認できなくて、漏水時に発見が遅れて被害が大きくなる問題があった。また、特許文献2の技術は、ヘッダーボックスが重くて施工し難く、コスト高となる問題があった。 However, the technique of Patent Document 1 has a problem that since the header is under the floor, it cannot be confirmed normally, and the discovery is delayed at the time of water leakage and the damage is increased. Further, the technique of Patent Document 2 has a problem that the header box is heavy and difficult to construct, resulting in high cost.

本発明の目的は、施工が簡単かつ低コストで、普段の確認も容易なヘッダー工法用のヘッダー用カバーを提供すること。 An object of the present invention is to provide a header cover for a header construction method, which is easy to construct, low cost, and easy to check in everyday life.

上記目的を達成するために請求項1の発明のヘッダー工法は、配管用のヘッダーを半筒状のヘッダー用カバーで覆い、当該ヘッダー用カバーを建物の露出面に直接固定することで、当該ヘッダーとヘッダー用カバーとを前記露出面に設置することを特徴とする。 In order to achieve the above object, the header construction method of the invention of claim 1 covers the header for piping with a semi-cylindrical header cover, and the header cover is directly fixed to the exposed surface of the building. And a header cover are installed on the exposed surface.

また、請求項2の発明は、ヘッダー工法に用いられるヘッダー用カバーであって、配管用のヘッダーを覆う半筒状の本体部と、当該本体部の縁部に設けられ建物の露出面に直接固定されるフランジ部とを備えたことを特徴とする。 The invention of claim 2 is a header cover used in the header construction method, which is provided on a semi-cylindrical main body portion that covers a header for piping and an edge portion of the main body portion and is directly applied to an exposed surface of a building. It is characterized by having a flange portion to be fixed.

本発明によれば、ヘッダーを建物の露出面に設置するため、普段の確認も容易で、漏水等の不具合を早期に発見できる。また、ヘッダー用カバーは半筒状であるため、ヘッダー用カバーのみでヘッダーの全体を覆う構成よりも軽量かつ安価であるし、露出面に対する固定作業も容易となる。 According to the present invention, since the header is installed on the exposed surface of the building, it is easy to check it normally, and defects such as water leakage can be detected at an early stage. Further, since the header cover has a semi-cylindrical shape, it is lighter and cheaper than a configuration in which the header cover alone covers the entire header, and the work of fixing to the exposed surface becomes easy.

以下、本発明を具体化した一実施形態について、図面を用いて詳細に説明する。
図7に示すように、給水配管を構成するヘッダー11は、一端が開口され他端が閉口されたストレート部12と、ストレート部12の一端部に設けられた流入側継手部13と、ストレート部12の延在方向における所定の位置からそれぞれ分岐して延びる複数(本実施形態においては3つ)の流出側継手部14とを備えている。流入側継手部13には水源側から延びる被覆15a付きの流入側パイプ15が、各流出側継手部14には各水栓へと延びる被覆16a付きの流出側パイプ16が、それぞれ接続されている。
Hereinafter, an embodiment embodying the present invention will be described in detail with reference to the drawings.
As shown in FIG. 7, the header 11 constituting the water supply pipe has a straight portion 12 having one end opened and the other end closed, an inflow side joint portion 13 provided at one end of the straight portion 12, and a straight portion. It is provided with a plurality of (three in the present embodiment) outflow side joint portions 14 that branch and extend from predetermined positions in the extending direction of the twelve. An inflow side pipe 15 with a coating 15a extending from the water source side is connected to the inflow side joint portion 13, and an outflow side pipe 16 having a coating 16a extending to each faucet is connected to each outflow side joint portion 14. ..

図1〜図6に示すように、ヘッダー用カバー10は、耐候性及び耐紫外線透過性の硬質樹脂材料(例えばポリ塩化ビニル)により形成されている。ヘッダー用カバー10は、本体部31とフランジ部35とを備えている。本体部31は、半円筒状で延在方向の一端(図1の左方側の端)が閉じられたストレート部32と、ストレート部32の延在方向における各位置からそれぞれ分岐して延びる、複数(本実施形態においては3つ)の半円筒状の分岐部33とを備えている。 As shown in FIGS. 1 to 6, the header cover 10 is made of a weather-resistant and ultraviolet-transparent hard resin material (for example, polyvinyl chloride). The header cover 10 includes a main body portion 31 and a flange portion 35. The main body 31 has a semi-cylindrical shape and a straight portion 32 in which one end (the left end in FIG. 1) is closed, and the straight portion 32 branches and extends from each position in the extending direction. It is provided with a plurality of (three in this embodiment) semi-cylindrical branch portions 33.

図1、図4及び図6に示すように、本体部31における4つの端には、逆U字状の内周縁を有する壁部36がそれぞれ形成されている。各壁部36の両方の基端には、内周側に向けてそれぞれ突出する突起部37が形成されている。 As shown in FIGS. 1, 4 and 6, wall portions 36 having an inverted U-shaped inner peripheral edge are formed at each of the four ends of the main body portion 31. At both base ends of each wall portion 36, protrusions 37 protruding toward the inner peripheral side are formed.

図1及び図6に示すように、フランジ部35は、本体部31の縁部から外側に向けて延出されている。フランジ部35は、本体部31の壁部36を除く縁部全体にわたって形成されている。フランジ部35の表面には、複数の非貫通のガイド穴38が互いに間隔をおいて形成されている。フランジ部35の裏面には、ガイド穴38を囲む環状リブ38aが形成されている。この環状リブ38aにより、フランジ部35が補強されるほか、ガイド穴38に連なる下孔をフランジ部35に形成する際に、穿孔具がガイドされる。 As shown in FIGS. 1 and 6, the flange portion 35 extends outward from the edge portion of the main body portion 31. The flange portion 35 is formed over the entire edge portion of the main body portion 31 excluding the wall portion 36. A plurality of non-penetrating guide holes 38 are formed on the surface of the flange portion 35 at intervals from each other. An annular rib 38a surrounding the guide hole 38 is formed on the back surface of the flange portion 35. The annular rib 38a reinforces the flange portion 35, and guides the drilling tool when forming a pilot hole connected to the guide hole 38 in the flange portion 35.

図6に示すように、ストレート部32における他端(図6の左方側の端)寄りの内周面には、ストレート部32の中心軸線を挟んで互いに対向する2対の規制リブ39が、ストレート部32の軸線方向に互いに間隔をおいて形成されている。各分岐部33の先端寄りの内周面には、分岐部33の中心軸線を挟んで互いに対向する2対の規制リブ40が、分岐部33の軸線方向に互いに間隔をおいて形成されている。 As shown in FIG. 6, on the inner peripheral surface of the straight portion 32 near the other end (the left end in FIG. 6), two pairs of regulating ribs 39 facing each other across the central axis of the straight portion 32 are provided. , Are formed at intervals in the axial direction of the straight portion 32. On the inner peripheral surface near the tip of each branch portion 33, two pairs of regulating ribs 40 facing each other with the central axis of the branch portion 33 interposed therebetween are formed at intervals in the axial direction of the branch portion 33. ..

図8に示すように、ヘッダー11は、ヘッダー用カバー10によって覆われるとともに、ヘッダー用カバー10が建物の露出面R(室内外の側壁面、室内の天井面又は室内の床面等)に直接固定されることで、ヘッダー用カバー10とともに露出面Rに設置される。当該固定は、ヘッダー用カバー10のフランジ部35を露出面Rに対して直接突き当て、フランジ部35のガイド穴38を介してビスBを露出面Rに対してねじ込むことにより行われる。 As shown in FIG. 8, the header 11 is covered with the header cover 10, and the header cover 10 is directly on the exposed surface R of the building (the side wall surface inside and outside the building, the ceiling surface inside the room, the floor surface inside the room, etc.). By being fixed, it is installed on the exposed surface R together with the header cover 10. The fixing is performed by directly abutting the flange portion 35 of the header cover 10 against the exposed surface R and screwing the screw B into the exposed surface R through the guide hole 38 of the flange portion 35.

ヘッダー用カバー10が露出面Rに固定された状態では、各壁部36及び突起部37(図7参照)が、対応する流入側パイプ15又は流出側パイプ16の被覆15a,16aに食い込んで隙間を無くし、当該隙間を経由した紫外線等の侵入を抑制する。これは、ヘッダー11等の紫外線による劣化を防止することにつながる。ヘッダー用カバー10が露出面Rに固定された状態では、各壁部36及び突起部37や規制リブ39,40(図7参照)が、対応する流入側パイプ15及び流出側パイプ16の被覆15a,16aに食い込むことで、熱収縮等に起因したヘッダー用カバー10に対する被覆15a,16aの変位が規制される。 When the header cover 10 is fixed to the exposed surface R, the wall portions 36 and the protrusions 37 (see FIG. 7) bite into the corresponding inflow side pipes 15 or the coatings 15a and 16a of the outflow side pipes 16 to form a gap. And suppresses the intrusion of ultraviolet rays and the like through the gap. This leads to prevention of deterioration of the header 11 and the like due to ultraviolet rays. In a state where the header cover 10 is fixed to the exposed surface R, each wall portion 36, the protrusion 37, and the regulation ribs 39, 40 (see FIG. 7) are covered with the corresponding inflow side pipe 15 and outflow side pipe 16 a. By biting into 16a, the displacement of the coatings 15a and 16a with respect to the header cover 10 due to heat shrinkage or the like is regulated.

以上のように本実施形態によれば、ヘッダー11を建物の露出面Rに設置するため、普段の確認も容易で漏水等の不具合を早期に発見できる。また、ヘッダー用カバー10は半円筒状であるため、ヘッダー用カバー10のみでヘッダー11の全体を覆う構成よりも軽量かつ安価であるし、フランジ部35を露出面Rに直接固定する簡単な作業で済む。 As described above, according to the present embodiment, since the header 11 is installed on the exposed surface R of the building, it is easy to check normally and defects such as water leakage can be detected at an early stage. Further, since the header cover 10 has a semi-cylindrical shape, it is lighter and cheaper than a configuration in which the header cover 10 alone covers the entire header 11, and a simple operation of directly fixing the flange portion 35 to the exposed surface R. It's done.

<別例>
上記実施形態は、例えば以下のように変更することもできる。
○ヘッダー用カバー10の分岐部33の数を4つ、5つ、6つ、7つ等に変更すること。
<Another example>
The above embodiment can be changed as follows, for example.
○ Change the number of branch portions 33 of the header cover 10 to 4, 5, 6, 7, etc.

○ヘッダー用カバー10(フランジ部35)を、露出面Rに対して接着剤または両面テープで固定すること。 ○ Fix the header cover 10 (flange portion 35) to the exposed surface R with an adhesive or double-sided tape.

○ヘッダー用カバー10の本体部31を、半円筒状以外の半筒状として半角筒状とすること。 ○ The main body 31 of the header cover 10 shall be a half-cylinder shape other than a semi-cylindrical shape.

○フランジ部35を削除して、本体部31の縁部を露出面Rに対して直接固定すること。 ○ Remove the flange portion 35 and fix the edge portion of the main body portion 31 directly to the exposed surface R.

○ヘッダー用カバー10の内部に、ヘッダー11がヘッダー用カバー10に対して相対移動することを防止する移動規制手段を設けること。このようにすれば、水撃作用等に起因してヘッダー用カバー10の内部でヘッダー11が動くことを防止できて、ヘッダー11がヘッダー用カバー10の内面に当接して異音等が発生することを防止できる。この移動規制手段としては、ヘッダー11の位置決めを行うリブ構造や、ヘッダー用カバー10とヘッダー11との間に介在される緩衝材であってもよい。当該緩衝材として、例えばポリウレタンフォーム等の発泡樹脂材を用いれば、保温効果も奏し得る。当該発泡樹脂材を用いる場合には、ヘッダー11及びヘッダー用カバー10を露出面Rに対して設置した後に、ヘッダー用カバー10とヘッダー11との間に発泡樹脂材を充填する手順を採用してもよい。 ○ Provide a movement restricting means inside the header cover 10 to prevent the header 11 from moving relative to the header cover 10. By doing so, it is possible to prevent the header 11 from moving inside the header cover 10 due to water hammer or the like, and the header 11 comes into contact with the inner surface of the header cover 10 to generate an abnormal noise or the like. Can be prevented. The movement restricting means may be a rib structure for positioning the header 11 or a cushioning material interposed between the header cover 10 and the header 11. If a foamed resin material such as polyurethane foam is used as the cushioning material, a heat retaining effect can also be obtained. When the foamed resin material is used, a procedure is adopted in which the header 11 and the header cover 10 are installed on the exposed surface R, and then the foamed resin material is filled between the header cover 10 and the header 11. May be good.
