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 in that since the header is under the floor, it cannot be normally confirmed, and discovery is delayed at the time of water leakage and damage is increased. Further, the technique of Patent Document 2 has a problem that the header box is heavy and difficult to construct, and the cost is high.

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を提供すること。また、当該ヘッダー工法に最適な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 construction method that is simple and inexpensive to construct, and that can be easily confirmed on a regular basis. Also, provide a header cover that is optimal for the header method.

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 is to cover the header for piping with a semi-cylindrical header cover, and fix the header cover directly to the exposed surface of the building. And a header cover are provided 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。   Further, the invention of claim 2 is a header cover used in a header construction method, and is provided on a semi-cylindrical main body portion covering a header for piping and an edge of the main body portion, and directly on an exposed surface of a building. And 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, the usual confirmation is easy, and problems such as water leakage can be found early. Further, since the header cover is semi-cylindrical, it is lighter and cheaper than a structure in which the entire header is covered with only the header cover, and the fixing operation to the exposed surface is facilitated.

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 includes 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. And a plurality of (three in this embodiment) outflow side joint portions 14 each extending in a branched manner from a predetermined position in the extending direction. An inflow side pipe 15 with a coating 15 a extending from the water source side is connected to the inflow side joint portion 13, and an outflow side pipe 16 with a coating 16 a 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. 1-6, the cover 10 for headers is formed with the hard resin material (for example, polyvinyl chloride) of a weather resistance and an ultraviolet-ray permeable property. 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 whose one end in the extending direction (the left end in FIG. 1) is closed, and extends from each position in the extending direction of the straight portion 32. A plurality of (three in the present embodiment) semi-cylindrical branch portions 33 are provided.

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 each having an inverted U-shaped inner peripheral edge are formed at four ends of the main body portion 31. Protrusions 37 projecting toward the inner peripheral side are formed at both base ends of each wall 36.

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 excluding the wall portion 36 of the main body portion 31. A plurality of non-through guide holes 38 are formed on the surface of the flange portion 35 at intervals. An annular rib 38 a surrounding the guide hole 38 is formed on the back surface of the flange portion 35. The annular rib 38 a reinforces the flange portion 35 and guides the punch when the pilot hole that continues to the guide hole 38 is formed 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, two pairs of regulating ribs 39 facing each other across the central axis of the straight portion 32 are formed on the inner peripheral surface near the other end (left end in FIG. 6) of the straight portion 32. The straight portions 32 are formed at intervals in the axial direction. Two pairs of regulating ribs 40 facing each other across the central axis of the branching portion 33 are formed on the inner peripheral surface near the tip of each branching portion 33 so as to be spaced apart from each other in the axial direction of the branching 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 indoor and outdoor side walls, the indoor ceiling surface, the indoor floor surface, 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。   In a state where the header cover 10 is fixed to the exposed surface R, each wall portion 36 and the projection portion 37 (see FIG. 7) bite into the corresponding coatings 15a and 16a of the inflow side pipe 15 or the outflow side pipe 16 to form gaps. To suppress the intrusion of ultraviolet rays or 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 in which the header cover 10 is fixed to the exposed surface R, each wall portion 36, the protrusion 37, and the regulation ribs 39 and 40 (see FIG. 7) are covered with the corresponding inflow side pipe 15 and the cover 15a of the outflow side pipe 16. 16a, the displacement of the coverings 15a, 16a with respect to the header cover 10 due to heat shrinkage or the like is restricted.

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 regularly, and problems such as water leakage can be found early. Further, since the header cover 10 is semi-cylindrical, it is lighter and cheaper than the configuration in which the header 11 is entirely covered with the header cover 10 alone, and the simple work of directly fixing the flange portion 35 to the exposed surface R. Just do it.

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 said embodiment can also 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 portion 31 of the header cover 10 is a half-tubular 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。 ○ The flange portion 35 is deleted, and the edge portion of the main body portion 31 is directly fixed 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。 A movement restricting means for preventing the header 11 from moving relative to the header cover 10 is provided inside the header cover 10. In this way, it is possible to prevent the header 11 from moving inside the header cover 10 due to a water hammer effect or the like, and the header 11 abuts against the inner surface of the header cover 10 to generate 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 buffer material, a heat retaining effect can be obtained. In the case of using the foamed resin material, a procedure for filling the foamed resin material between the header cover 10 and the header 11 after the header 11 and the header cover 10 are installed on the exposed surface R is adopted. Also good.
