Description

本発明は、流体配管のエルボ部の外周部を覆う断熱材の外周面に沿って付設可能で、前記エルボ部の湾曲半径方向に沿う分割線で区画され、且つ、板金を筒状に曲げた複数の分割外装部材の分割端縁部同士を連結してエビ管形状に形成し、エビ管形状に連結した前記複数の分割外装部材における屈曲内側部で配管周方向の両端部夫々を、連結可能に構成してある板金製外装材及び板金製外装材の施工方法に関する。 The present invention can be attached along the outer peripheral surface of a heat insulating material that covers the outer peripheral portion of an elbow portion of a fluid pipe, is partitioned by a dividing line along the curved radial direction of the elbow portion, and is formed by bending a sheet metal into a cylindrical shape. The divided end edges of the plurality of divided exterior members are connected to each other to form a shrimp-tube shape, and both ends in the pipe circumferential direction can be connected at the bent inner portions of the plurality of divided exterior members connected in the shrimp-tube shape. The present invention relates to a sheet metal exterior material and a method for constructing the sheet metal exterior material.

従来、前記板金製外装材は、図５（ａ）～（ｃ）に示すように、エビ管形状に連結した前記複数の分割外装部材４における屈曲内側部５の概略曲線と屈曲外側部６の概略曲線とを、略同心円状に形成してあり、エビ管形状に連結した前記複数の分割外装部材４における屈曲内側部５で配管周方向の両端部夫々を、ビス１０（図５（ｃ））を使って連結してあった（周知技術であって、適切な公報が見当たらない）。 Conventionally, as shown in FIGS. 5(a) to 5(c), the sheet metal exterior material has a general curve of the inner bent portion 5 and the outer bent portion 6 of the plurality of divided exterior members 4 connected in a shrimp tube shape. The curved lines are formed substantially concentrically, and both ends in the circumferential direction of the pipe are attached to each of the bent inner portions 5 of the plurality of divided exterior members 4 connected in the shape of a shrimp pipe by screws 10 (Fig. 5(c)). ) (well-known technology, no appropriate publication found).

しかし、エビ管形状に連結した前記複数の分割外装部材４における屈曲内側部５で配管周方向の両端部夫々を、ビス１０を使って連結する施工法では、そのビス１０により下地の防水材、防湿材や断熱材等に穴を開けてしまったり、傷をつけてしまう危険性があり、また、ビス１０を装着するまで、分割外装部材４における屈曲内側部５で配管周方向の両端部夫々を重ねて、仮固縛材で締め付けて安定しておかなければならず、配管現場で手間が多くかかり、施工性が悪くなるという問題があった。 However, in the construction method of connecting both ends of the pipe circumferential direction at the bent inner part 5 of the plurality of divided exterior members 4 connected in a shrimp pipe shape using screws 10, the waterproof material of the base with the screws 10, There is a danger of making a hole or damaging the moisture-proof material or heat insulating material. , and must be stabilized by tightening them with temporary lashing materials.

従って、本発明の目的は、上記問題点を解消し、板金製外装材の配管現場における施工性を向上させるところにある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above problems and to improve the workability of the sheet metal exterior material at the piping site.

本発明の板金製外装材の第１の特徴構成は、流体配管のエルボ部の外周部を覆う断熱材の外周面に沿って付設可能で、前記エルボ部の湾曲半径方向に沿う分割線で区画され、且つ、板金を筒状に曲げた複数の分割外装部材の分割端縁部同士を連結してエビ管形状に形成し、エビ管形状に連結した前記複数の分割外装部材における屈曲内側部で配管周方向の両端部夫々を、連結可能に構成してある板金製外装材であって、エビ管形状に連結した前記複数の分割外装部材において、屈曲内側部と屈曲外側部との距離を、屈曲始端部及び屈曲終端部の前記分割外装部材よりも屈曲中間部の前記分割外装部材の方が大になるように形成し、前記分割外装部材における屈曲内側部の配管周方向の両端部夫々にハゼを設けて、それらの前記ハゼ同士を係合連結可能に構成したところにある。 A first characteristic configuration of the sheet metal exterior material of the present invention is that it can be attached along the outer peripheral surface of the heat insulating material that covers the outer peripheral portion of the elbow portion of the fluid pipe, and is divided by the dividing line along the curved radial direction of the elbow portion. and the divided end edges of a plurality of divided exterior members each formed by bending a sheet metal into a cylindrical shape are connected to each other to form a shrimp-tube shape. A sheet metal exterior member configured to be able to connect both ends in the circumferential direction of a pipe, wherein in the plurality of divided exterior members connected in a shrimp tube shape, the distance between the bent inner portion and the bent outer portion is The split armor member at the bend intermediate part is formed to be larger than the split armor member at the bend start end and the bend end part, and the split armor member is formed at both ends in the pipe circumferential direction of the bend inner part of the split armor member. Seams are provided so that the seams can be engaged and connected to each other.

本発明の第１の特徴構成によれば、エビ管形状に連結した前記複数の分割外装部材において、屈曲内側部と屈曲外側部との距離を、屈曲始端部及び屈曲終端部の前記分割外装部材よりも屈曲中間部の前記分割外装部材の方が大になるように形成することにより、屈曲内側部の概略円弧の曲率半径が大きくなり、そのために、屈曲内側部の概略円弧の曲率半径の小さいものに比べて、分割端縁部同士を連結した複数の分割外装部材全体の屈曲内側部で配管周方向の両端部夫々を、離間及び近接操作が軽く行えるようになって、エルボ部の外周部を覆う断熱材に対して外側から包み込むようにして装着しやすくなるばかりか、分割外装部材における屈曲内側部の配管周方向の両端部夫々に設けたハゼ同士の係合連結が容易になり外装材の施工が容易になる。 According to the first characteristic configuration of the present invention, in the plurality of divided exterior members connected in a shrimp tube shape, the distance between the bent inner portion and the bent outer portion is set to By forming the divided exterior member so that it is larger than the intermediate portion of the bend, the radius of curvature of the general arc of the inner portion of the bend is increased, and therefore the radius of curvature of the approximate arc of the inner portion of the bend is small. Compared to the above, it is possible to easily separate and approach both ends of the pipe in the circumferential direction at the bent inner part of the whole of the divided exterior members that connect the divided edges, and the outer circumference of the elbow part. Not only is it easier to attach to the heat insulating material that covers the outside of the split exterior member, but it is also easy to engage and connect the seams provided at both ends in the pipe circumferential direction of the bent inner portion of the divided exterior member. construction becomes easier.

本発明の第２の特徴構成は、前記複数の分割外装部材の分割端縁部同士の連結部をハゼ掛け連結構造に形成してエルボ部に対する断熱材を被覆可能に構成したところにある。 A second characteristic configuration of the present invention resides in that the connecting portions between the divided edge portions of the plurality of divided exterior members are formed in a seam connection structure so that the elbow portion can be covered with a heat insulating material.

本発明の第２の特徴構成によれば、本発明の第１の特徴構成による上述の作用効果を叶えることができるのに加えて、複数の分割外装部材同士の連結組み立ても、一般的にエルボ部においてエビ管形状に成型するのに溶接により連結する技術に比べて、ハゼ掛け連結構造に形成することにより製作も容易になって、製作作業の効率化を向上させることができる。 According to the second characteristic configuration of the present invention, in addition to being able to achieve the above-described effects of the first characteristic configuration of the present invention, the plurality of divided exterior members can generally be connected and assembled using elbows. Compared to the technique of connecting by welding to form a shrimp tube shape at the part, by forming the seam connecting structure, the manufacturing becomes easier and the efficiency of the manufacturing work can be improved.

本発明の第３の板金製外装材の施工方法は、前記分割外装部材における屈曲内側部の配管周方向の両端部夫々を離間させながら流体配管のエルボ部の外周部を覆う断熱材の外から前記板金製外装材を被覆し、前記ハゼ同士を近接させて互いに係合連結するところにある。 In the third method of installing a sheet metal exterior member of the present invention, the heat insulating material covering the outer peripheral portion of the elbow portion of the fluid pipe is separated from the both ends in the pipe circumferential direction of the bent inner portion of the divided exterior member from the outside. It covers the sheet metal exterior material, brings the seams close to each other, and engages and connects them.

本発明の第３の特徴構成によれば、屈曲内側部の概略円弧の曲率半径の小さいものに比べて、分割端縁部同士を連結した複数の分割外装部材全体の屈曲内側部で配管周方向の両端部夫々を、離間及び近接操作が軽く行え、エルボ部の外周部を覆う断熱材に対して外側から包み込むようにして装着しやすくなり、分割外装部材における屈曲内側部の配管周方向の両端部夫々に設けたハゼ同士の係合連結することにより、従来のようにビスを使わないために、低温配管の断熱(保冷)を行うのに、断熱材と外装材の間に位置する防湿層を貫通せず、板金製外装材を装着でき、板金製外装材による配管の保護を容易にできる。 According to the third characteristic configuration of the present invention, compared to the case where the radius of curvature of the approximate circular arc of the inner curved portion is small, the inner curved portion of the entire plurality of split exterior members connecting the split edge portions together in the pipe circumferential direction Both ends of the pipe can be easily separated and approached, and can be easily attached to the heat insulating material that covers the outer periphery of the elbow by wrapping it from the outside. By engaging and connecting the seams provided in each part, unlike conventional screws, a moisture-proof layer positioned between the heat insulating material and the exterior material is used to insulate (cold insulation) the low-temperature piping. The sheet metal exterior material can be attached without penetrating the pipe, and the piping can be easily protected by the sheet metal exterior material.

In the drawings, the parts indicated by the same reference numerals as those of the conventional example indicate the same or corresponding parts.

図１～図３に示すように、高温流体や低温流体を流通させる流体配管１に対して、それら流体配管１の外周部を断熱材２で覆って、流通流体の熱エネルギーが外部にリークするのを防止すべく配管断熱構造を構成してある。
尚、断熱材２は、高温流体が配管内を流通する場合は、例えば、珪酸カルシウム成型材やロックウール、グラスウール等の無機繊維綿材などの無機材から成るものを使用し、低温流体が配管内を流通する場合は、例えば発泡ポリウレタン、発泡ポリスチレン、発泡ポリエチレン等の有機発泡樹脂材が使用されることが多い。
そして、上記配管断熱構造において、断熱材２の外周部を覆って、断熱材２を風雨や外力などから保護するために、直管部１Ａにおける円筒形の外装材３とエルボ部１Ｂにおける略曲管状の外装材３とを、夫々板金製で曲げ加工して断熱材２の外側に付設してある。
特にエルボ部１Ｂにおいては、エルボ部１Ｂの外周部を覆う断熱材２の外周面に沿って付設可能で、エルボ部１Ｂの湾曲半径方向に沿う分割線で区画され、且つ、板金を筒状に曲げた複数の分割外装部材４の分割端縁部４Ａ同士を連結してエビ管形状に形成し、エビ管形状に連結した複数の分割外装部材４における屈曲内側部５で配管周方向の両端部夫々を、連結可能に構成してある板金製外装材が設けてある。 As shown in FIGS. 1 to 3, the outer periphery of the fluid pipe 1 through which the high-temperature fluid and the low-temperature fluid are circulated is covered with a heat insulating material 2 so that the heat energy of the circulating fluid leaks to the outside. In order to prevent this, a piping insulation structure is constructed.
When the high-temperature fluid flows through the piping, the heat insulating material 2 is made of an inorganic material such as calcium silicate molded material, rock wool, glass wool, or other inorganic fiber material. When circulating inside, for example, organic foamed resin materials such as foamed polyurethane, foamed polystyrene, and foamed polyethylene are often used.
In the pipe insulation structure, in order to cover the outer peripheral portion of the heat insulating material 2 and protect the heat insulating material 2 from wind, rain, external force, etc., the cylindrical exterior material 3 at the straight pipe portion 1A and the substantially curved portion at the elbow portion 1B are provided. A tubular sheathing material 3 is made of sheet metal and is attached to the outside of the heat insulating material 2 by bending.
In particular, in the elbow portion 1B, it can be attached along the outer peripheral surface of the heat insulating material 2 covering the outer peripheral portion of the elbow portion 1B. The divided edge portions 4A of the plurality of bent divided exterior members 4 are connected to each other to form a shrimp pipe shape, and both ends in the pipe circumferential direction are formed at the bent inner portions 5 of the plurality of divided exterior members 4 connected in the shrimp pipe shape. A sheet metal exterior member is provided so as to be connectable to each other.

図３（ａ）～（ｆ）の６面図に示すように、複数の分割外装部材４において、前記分割線に沿う分割端縁部４Ａ同士をハゼ掛け（図４（ｂ））により連結してエビ管形状にエルボ部１Ｂに対する断熱材２を被覆可能に構成し、そのエビ管形状に連結した複数の分割外装部材４において、屈曲内側部５と屈曲外側部６との距離（図６のＡとＢ）を、屈曲始端部及び屈曲終端部の分割外装部材４の距離（図６のＡ）よりも屈曲中間部の分割外装部材４の距離（図６のＢ）の方が大になるように形成し、分割外装部材４における屈曲内側部５の配管周方向の両端部夫々にハゼ７（図４（ａ））を設けて、それらのハゼ７同士を係合連結可能に構成してある。 As shown in the six views of FIGS. 3(a) to 3(f), in a plurality of split exterior members 4, split edge portions 4A along the split lines are connected by seams (FIG. 4(b)). The elbow portion 1B can be covered with the heat insulating material 2 in the shape of a shrimp tube, and in the plurality of divided exterior members 4 connected in the shape of a shrimp tube, the distance between the bent inner portion 5 and the bent outer portion 6 (Fig. 6 A and B), the distance (B in FIG. 6) of the split armor member 4 at the intermediate part of the bend (B in FIG. 6) is larger than the distance (A in FIG. 6) between the split armor members 4 at the bend start part and the bend end part. A seam 7 (FIG. 4(a)) is provided at each end in the pipe circumferential direction of the bent inner portion 5 of the divided exterior member 4, and the seams 7 are configured to be engaged and connected to each other. be.

尚、断熱材２の直径は、３００～１０００ｍｍで、前記板金を筒状に曲げた分割外装部材４は、塗装溶融亜鉛メッキ鋼板（ＪＩＳ Ｇ ３３１２）で、厚さ０．２７～０．４０ｍｍの金属板で製作してある。 The diameter of the heat insulating material 2 is 300 to 1000 mm, and the divided exterior member 4 formed by bending the sheet metal into a cylindrical shape is a coated hot-dip galvanized steel sheet (JIS G 3312) with a thickness of 0.27 to 0.40 mm. Manufactured from metal plate.

前記複数の分割外装部材４でエビ管形状に製作するために、図６に示すように、まず配管のエルボ部１Ｂの屈曲外側部６の概略の外側曲線の第１曲率中心Ｐ１と同心円上で、配管の直管部１Ａに対する円筒形の外装材３と連設可能な半径Ｒ１の外側曲線と概略曲線上の屈曲外側部６を形成し、外装材３の屈曲内側部５を、第１曲率中心Ｐ１とは異なり、且つ、エルボ部１Ｂの湾曲内側からより遠く離れた位置に置く第２曲率中心Ｐ２の半径Ｒ２の円弧上に形成し、且つ、屈曲内側部５と屈曲外側部６との距離（図６のＡ又はＢ）を、屈曲始端部及び屈曲終端部の分割外装部材４の距離Ａよりも屈曲中間部の分割外装部材４の距離Ｂの方が大になるように形成してある。 In order to manufacture the plurality of divided exterior members 4 in the shape of a shrimp pipe, first, as shown in FIG. , an outer curve with a radius R1 that can be connected to the cylindrical exterior material 3 for the straight pipe portion 1A of the pipe, and a bent outer part 6 on a schematic curve are formed, and the bent inner part 5 of the exterior material 3 is formed with the first curvature It is formed on an arc with a radius R2 of the second center of curvature P2 which is different from the center P1 and is located farther from the curved inner side of the elbow portion 1B, and the curved inner portion 5 and the curved outer portion 6 are formed on the arc. The distance (A or B in FIG. 6) is formed so that the distance B of the split armor member 4 at the bend intermediate part is larger than the distance A of the split armor member 4 at the bend start part and the bend end part. be.

したがって、屈曲内側部５の側面視形状は、より直線に近づくように曲率が小さくなって、分割外装部材４における屈曲内側部５の配管周方向の両端部夫々に設けたハゼ７同士の係合連結が容易になり外装材３の施工が容易になると共に、分割端縁部４Ａ同士を連結した複数の分割外装部材４全体の屈曲内側部５で配管周方向の両端部夫々を、離間及び近接操作が軽く行えるようになって、エルボ部１Ｂの外周部を覆う断熱材２に対して外側から包み込むようにして装着しやすくなる。 Therefore, the curvature of the curved inner portion 5 in a side view becomes closer to a straight line, and the seams 7 provided at both ends of the curved inner portion 5 of the split exterior member 4 in the pipe circumferential direction engage with each other. The connection is facilitated, and the construction of the exterior material 3 is facilitated. The operation can be performed easily, and it becomes easy to attach the heat insulating material 2 covering the outer peripheral part of the elbow part 1B so as to wrap it from the outside.

したがって、板金製外装材の施工にあたっては、予め複数の分割外装部材４の分割端縁部４Ａ同士をハゼ掛けにより連結しておき、分割外装部材４における屈曲内側部５の配管周方向の両端部夫々を離間させながら流体配管のエルボ部１Ｂの外周部を覆う断熱材２の外から板金製外装材を被覆し、ハゼ７同士を近接させて互いに係合連結する。
