Description

【発明の属する技術分野】
本発明は、周方向に複数に分割された断熱材を配管の外周に取り付け施工する際に使用する配管用断熱材施工補助具に関する。
【0002】
【従来の技術】
このような配管用断熱材の施工では、施工の対象となる配管の外周に複数の断熱材を配設し、その外周に金属製の線材などからなる緊縛材を巻き付けて固定するのであるが、ひとりの作業者が、複数の断熱材を配管周りに保持しながら、その外周に緊縛材を巻き付けて固定するのはきわめて困難な作業であり、通常、少なくともひとりの作業者が複数の断熱材を保持し、他の作業者が緊縛材を巻き付けて固定していたのが実情である。
したがって、配管用断熱材の施工に最低2人の作業者が必要となり、配管の管径が大きくなると、3人以上の作業者を必要とする場合もあり、それが施工費用のコストアップを招く原因ともなっていた。
【0003】
そこで、かかる施工作業をひとりの作業者で可能にするため、従来、施工補助具としてゴムバンドが使用されていた。
具体的には、配管の長手方向の1箇所あるいは2箇所において、その外周にゴムバンドを緩めに巻き付けて端部どうしを互いに結び、そのゴムバンドと配管外周との間に断熱材を差し込み、必要に応じて、そのゴムバンドを配管の径方向に引っ張りながら断熱材を順次差し込んで仮止めし、その仮止めした状態で、断熱材の外周に緊縛材を巻き付けて固定し、その後、仮止め用のゴムバンドを外して施工していた(現実に実施されているが、仮止め用のゴムバンドに言及した特許公報などは見当たらない)。
【0004】
【発明が解決しようとする課題】
しかし、仮止め用のゴムバンドを使用する場合、当然、配管の外周にゴムバンドを巻き付けて端部どうしを結ぶ作業が必要となり、また、配管から外す際には結び目を解く作業が必要となる。さらに、配管の外周にゴムバンドを緩めに巻き付けて結んでも、その巻き付け具合が緩すぎたり、逆に、きつすぎたりすると、再度結び直す作業が必要となって作業が煩雑になる欠点があった。
特に、配管への施工においては、上述した作業を配管に沿って何度も繰り返す必要があるため、非常に煩雑な作業となり、この点に改良の余地があった。
また、このような配管用断熱材の施工では、配管内を高温や低温の流体が通流する状態のままで施工することもあり、高温の流体が通流する場合にはゴムバンドが溶ける可能性があり、低温の流体が通流する場合にはゴムバンドが硬くなって所望どおりの作業ができなくなる可能性もあって、実際上、ゴムバンドの使用が不可能なこともある。
【0005】
本発明は、このような従来の問題点に着目したもので、その目的は、たとえひとりの作業者であっても、また、たとえ配管内を高温や低温の流体が通流していても、配管外周への断熱材の取り付け施工を容易かつ迅速に行うことのできる配管用断熱材施工補助具を提供することである。
【0006】
【課題を解決するための手段】
請求項1の発明の特徴構成は、周方向に複数に分割された断熱材を配管の外周に取り付け施工する際に使用する配管用断熱材施工補助具であって、前記断熱材をその内面側に保持自在で、かつ、前記配管の長手方向に沿う軸心周りに回動自在に連結された複数の保持枠体と、その保持枠体に設けられて互いに連結および離脱可能に構成された一対の連結具を備え、前記複数の保持枠体を前記配管の外周に巻き付けて前記連結具により連結および離脱可能に構成されているところにある。
【0007】
請求項1の発明の特徴構成によれば、周方向に複数に分割された断熱材を配管の外周に取り付け施工する際に使用する配管用断熱材施工補助具が、断熱材をその内面側に保持自在で、かつ、配管の長手方向に沿う軸心周りに回動自在に連結された複数の保持枠体と、その保持枠体に設けられて互いに連結および離脱可能に構成された一対の連結具を備え、複数の保持枠体を配管の外周に巻き付けて連結具により連結および離脱可能に構成されているので、複数の保持枠体の内面側に断熱材を保持させて配管の外周に巻き付けて連結具により連結することによって、複数の断熱材を配管の外周に保持させることができ、施工完了後においては、連結具を離脱することによって複数の保持枠体を配管外周から取り外すことができる。
したがって、従来のようにいちいち結んだり結び目を解く作業が不用となり、たとえひとりの作業者であっても、配管外周への断熱材の取り付け施工を容易かつ迅速に行うことができ、断熱材の取り付け施工に要する費用を低減することができるとともに、断熱材を保持する保持枠体を高温あるいは低温に耐え得る材料で構成することにより、たとえ配管内を高温あるいは低温の流体が通流していても、断熱材の取り付け施工を所望どおりに行うことができる。
【0008】
請求項2の発明の特徴構成は、前記連結具の長さが調節可能に構成され、その連結具の長さ調節によって前記複数の保持枠体の巻き付け径が調節できるように構成されているところにある。
【0009】
請求項2の発明の特徴構成によれば、連結具の長さが調節可能に構成され、その連結具の長さ調節によって複数の保持枠体の巻き付け径が調節できるように構成されているので、施工の対象となる配管の径が多少変わっても、また、断熱材の厚みが多少変わっても、同じ施工補助具による対応が可能となり、施工補助具の汎用性が向上する。
【0010】
請求項3の発明の特徴構成は、前記複数の保持枠体に対して前記断熱材を保持させる仮止め手段が設けられているところにある。
【0011】
請求項3の発明の特徴構成によれば、複数の保持枠体に対して断熱材を保持させる仮止め手段が設けられているので、その仮止め手段を使用して断熱材を各保持枠体に対して所望の位置に保持させることにより、各断熱材を配管の外周の配設保持させた状態で、比較的容易に各断熱材間の目地幅を均一化したり、断熱材どうしを密着させて見栄えを向上させることができる。
特に、その目地部にポリウレタンフォームなどの目地材を注入する場合には、目地部への目地材の施工がより一層確実となり、目地部からの熱の放散あるいは熱の侵入を良好に阻止することができる。
【0012】
【発明の実施の形態】
本発明による配管用断熱材施工補助具につき、その実施の形態を図面に基づいて説明する。
この配管用断熱材施工補助具は、図1〜図3に示すように、半円筒状に形成された鳥かごのような2つの保持枠体1を備え、それら両保持枠体1は、複数の蝶番2によって軸心L周りに相対回動自在に連結されている。
各保持枠体1は、ステンレスや鉄などの金属製材料により形成され、互いに対向する一対の半円部材1a、両半円部材1aの端部どうしを連結する一対の辺部材1b、および、両半円部材1aの中間部どうしを連結する中間部材1cなどが互いに溶接されて鳥かご状に構成されていて、両保持枠体1の一方の辺部材1bどうしが蝶番2により相対回動自在に連結されている。
【0013】
両保持枠体1のうち、一方の保持枠体1においては、蝶番2と対向する側の辺部材1bの外面にフック3aが突設され、他方の保持部材1においては、蝶番2と対向する側の辺部材1bの外面に金具3cを介して適当な長さを有するチェン3bの一端が回動自在に取り付けられている。
両保持枠体1のフック3aとチェン3bは、互いに連結および離脱可能な一対の連結具3を構成し、フック3aに対してチェン3bの連結箇所を適宜選択することで、その連結具3の長さを調節して、後に詳しく説明するように、両保持枠体1の巻き付け径が調節できるように構成されている。
そして、フック3aが突設された辺部材1bの内面側には、後に詳しく説明するように、仮止め手段としての保持突片4が、辺部材1bの長手方向に適当距離を置いて一対突設されている。
【0014】
つぎに、この施工補助具の使い方について説明する。
例えば、施工の対象となる配管Pが8インチ管(外径約206mm)の場合、図4および図5に示すように、周方向に2分割された厚み65mm程度の断熱材Aが使用され、その断熱材Aを両保持枠体1の内面側にそれぞれ保持させ、両保持枠体1の回動軸心Lが配管Pの長手方向に沿うようにして、チェン3bが取り付けられた方の保持枠体1を配管Pの外周上面に載置する。
すると、他方の保持枠体1は吊下することになるが、吊下した方の断熱材Aは保持突片4に当接するので、断熱材Aは保持枠体1に対して所定の位置に確実に保持される。
【0015】
つぎに、吊下した方の保持枠体1を軸心L周りに回動させて持ち上げ(図5参照)、両保持枠体1を配管Pの外周に巻き付けるとともに、チェン3bをフック3aに連結して、両保持枠体1を配管Pの外周に取り付ける。
その際、フック3aに対するチェン3bの連結箇所を選択することにより、フック3aとチェン3bからなる連結具3の長さを調節することができ、連結具3の長さ調節によって、両保持枠体1の巻き付け径が調節できるので、対象とする配管Pの径や断熱材Aの厚みに応じて適宜調節することになる。
その結果、図6に示すように、両保持枠体1により2つの断熱材Aを配管Pの外周にしっかりと仮止めすることができ、仮止めした状態で、断熱材Aの外周にステンレスや鉄製の線材やガラスフィラメントテープなどからなる緊縛材5を巻き付けて強固に固定して取り付け、例えば、配管Pが低温の流体を通流させるものであれば、各断熱材A間の目地部分にポリウレタンフォームなどの目地材6を注入するのであり、目地材6の注入前あるいは注入後に保持枠体1を取り外す。
【0016】
その後、必要な場合には、図7に示すように、その断熱材Aの外周にさらに別の断熱材Bを取り付けることになる。つまり、先に取り付けた断熱材Aを内層側の断熱材として、その外側に外層側の断熱材Bを取り付けるのであり、その外層側の断熱材Bは、例えば、周方向に2分割された厚み70mm程度の断熱材Bが使用される。
断熱材Bの取り付けも、断熱材Bを両保持枠体1の内面側にそれぞれ保持させ、一方の保持枠体1を断熱材Aの外周上面に載置し、他方の保持枠体1を軸心L周りに回動させ、チェン3bをフック3aに連結して取り付ける。
その際、断熱効果を確実にするため、外層側断熱材B間の目地部分が内層側断熱材A間の目地部分と重ならないように配設し、その後、外層側断熱材Bの外周に緊縛材5を巻き付け、かつ、各断熱材B間の目地部分に目地材6を注入するとともに、保持枠体1を取り外して施工を完了する。
【0017】
〔別実施形態〕
(1)先の実施形態では、半円筒状に形成された2つの保持枠体1を軸心L周りに相対回動自在に連結した例を示したが、図8に示すように、例えば、合計4つの保持枠体1をそれぞれ軸心L周りに相対回動自在に連結し、各保持枠体1の内面側に周方向に4つに分割された断熱材A,Bをそれぞれ保持させるように構成することもできる。
要するに、断熱材A,Bの分割数は配管Pの径などに応じて変わるものであり、その断熱材A,Bの分割数に応じて、連結する保持枠体1の数を変えるのが望ましく、必要な場合には、ひとつの保持枠体1に2つの断熱材A,Bを保持させるように構成することもできる。
また、配管Pの外周に内層側断熱材Aと外層側断熱材Bを二層に取り付け施工した例を示したが、断熱材を一層だけ取り付け施工する際にも、三層以上取り付け施工する際にも適用可能である。
【0018】
(2)先の実施形態では、各保持枠体1を金属材料により形成した例を示したが、例えば、プラスチックやFRPなどの各種合成樹脂をはじめとして、木製の集成材やセラミックなどで形成することもでき、さらに、その具体的な構成についても、鳥かごのようなものに限らず、例えば、彎曲した中実の板状体により構成することもできる。
連結具3に関しても、フック3aとチェン3bに限るものではなく、例えば、適当な長さを有する一対の面ファスナなど、種々の構成のものを使用することができ、また、仮止め手段4に関しても、先の実施形態で示した保持突片に限らず、例えば、両面テープなどで構成することもできる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a pipe heat insulating material construction auxiliary tool used when a plurality of circumferentially divided heat insulating materials are attached to the outer periphery of a pipe and used for the work.
[0002]
[Prior art]
In the construction of such a pipe heat insulating material, a plurality of heat insulating materials are arranged on the outer circumference of the pipe to be installed, and a binding material such as a metal wire is wound around the outer circumference and fixed. It is extremely difficult for one worker to wrap and fasten the binding material around the outer circumference of the pipe while holding multiple pieces of heat insulation around the pipe. It is the fact that it was held and another worker wound and fixed the binding material.
Therefore, at least two workers are required for the installation of the heat insulating material for pipes, and when the pipe diameter is large, three or more workers may be required, which leads to an increase in the construction cost. It was also the cause.
[0003]
Therefore, in order to enable such a construction work by one worker, a rubber band has conventionally been used as a construction aid.
Specifically, at one or two locations in the longitudinal direction of the pipe, a rubber band is loosely wound around its outer circumference to tie the ends together, and a heat insulating material is inserted between the rubber band and the outer circumference of the pipe. In accordance with the above, while temporarily pulling the rubber band in the radial direction of the pipe and inserting the insulation material temporarily, temporarily fix it, wrapping the binding material around the outer periphery of the insulation material and fixing it, and then use it for temporary fixing (It is actually implemented, but there is no patent publication referring to the rubber band for temporary fixing).
[0004]
[Problems to be solved by the invention]
However, when using a rubber band for temporary fixing, it is naturally necessary to wrap the rubber band around the outer periphery of the pipe and tie the ends together, and when removing it from the pipe, it is necessary to untie the knot . Furthermore, even if the rubber band is loosely wound around the outer circumference of the pipe and tied, if the degree of winding is too loose or, on the contrary, too tight, a work of re-tying is necessary, and the work becomes complicated. .
In particular, in the construction of pipes, the above-mentioned work needs to be repeated many times along the pipe, so that the work becomes very complicated, and there is room for improvement in this point.
In addition, when applying such heat insulating material for pipes, there is also a case where high temperature or low temperature fluid flows through the pipe, and the rubber band may melt when high temperature fluid flows. When a low-temperature fluid flows through the rubber band, the rubber band may be hard and may not be able to perform a desired operation, so that the rubber band may not be used in practice.
[0005]
The present invention focuses on such a conventional problem, and its purpose is to make it easy for even a single worker to operate a pipe even if a high-temperature or low-temperature fluid flows through the pipe. An object of the present invention is to provide a heat insulating material installation aid for piping that can easily and quickly attach and operate a heat insulating material to an outer periphery.
[0006]
[Means for Solving the Problems]
A characteristic configuration of the invention according to claim 1 is a piping heat insulating material construction aid used when a heat insulating material divided into a plurality in the circumferential direction is attached to the outer periphery of a pipe and is constructed, wherein the heat insulating material is disposed on the inner surface side. A plurality of holding frames connected rotatably around an axis along the longitudinal direction of the pipe, and a pair provided on the holding frame and configured to be connected to and detached from each other. Wherein the plurality of holding frames are wound around the outer periphery of the pipe so that the holding frame can be connected and disconnected by the connecting tool.
[0007]
According to the characteristic configuration of the first aspect of the present invention, the heat insulating material for piping used when attaching the heat insulating material divided into a plurality of pieces in the circumferential direction to the outer periphery of the pipe is used to attach the heat insulating material to the inner surface side. A plurality of holding frames that are freely held and rotatably connected around an axis along the longitudinal direction of the pipe, and a pair of connections provided on the holding frames and configured to be connected to and detached from each other; The holding frame is wrapped around the outer circumference of the pipe so that it can be connected and disconnected by the connecting tool, so that the insulating material is held on the inner surface side of the plurality of holding frames and wound around the outer circumference of the pipe. By connecting with the connecting tool, a plurality of heat insulating materials can be held on the outer periphery of the pipe, and after completion of the construction, the plurality of holding frames can be removed from the outer circumference of the pipe by detaching the connecting tool. .
Therefore, the work of tying and breaking the knot as in the conventional case is unnecessary, and even a single worker can easily and quickly perform the installation work of the heat insulating material on the outer periphery of the pipe, and install the heat insulating material. The cost required for construction can be reduced, and the holding frame that holds the heat insulating material is made of a material that can withstand high or low temperature, even if high-temperature or low-temperature fluid flows through the piping, The installation of the heat insulating material can be performed as desired.
[0008]
A feature of the invention according to claim 2 is that the length of the connecting member is adjustable and the winding diameter of the plurality of holding frames can be adjusted by adjusting the length of the connecting member. It is in.
[0009]
According to the characteristic configuration of the second aspect of the present invention, the length of the connecting member is adjustable, and the winding diameter of the plurality of holding frames can be adjusted by adjusting the length of the connecting member. Even if the diameter of the pipe to be constructed changes slightly or the thickness of the heat insulating material changes slightly, the same construction aid can be used, and the versatility of the construction aid is improved.
[0010]
A feature of the invention according to claim 3 is that temporary fixing means for holding the heat insulating material with respect to the plurality of holding frames is provided.
[0011]
According to the characteristic configuration of the third aspect of the present invention, since the temporary fixing means for holding the heat insulating material with respect to the plurality of holding frames is provided, the heat insulating material is used to hold the heat insulating material using the temporary fixing means. By holding each heat insulator at the desired position with respect to the outer periphery of the pipe, the joint width between the heat insulators can be relatively easily uniformized, and the heat insulators can be closely attached to each other. Appearance can be improved.
In particular, when a joint material such as polyurethane foam is injected into the joint, the joint material is more reliably applied to the joint, and heat from the joint or heat is prevented from entering. Can be.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a piping heat insulating material construction aid according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, this piping heat insulating material construction aid includes two holding frames 1 such as a birdcage formed in a semi-cylindrical shape. The hinge 2 is connected so as to be relatively rotatable around the axis L.
Each holding frame 1 is formed of a metal material such as stainless steel or iron, and has a pair of semicircular members 1a facing each other, a pair of side members 1b connecting ends of the two semicircular members 1a, and a pair of side members 1b. Intermediate members 1c and the like for connecting the intermediate portions of the semicircular members 1a are welded to each other to form a birdcage, and one side member 1b of both holding frames 1 is relatively rotatably connected to each other by the hinge 2. Have been.
[0013]
Of the two holding frames 1, one of the holding frames 1 has a hook 3 a protruding from the outer surface of the side member 1 b facing the hinge 2, and the other holding member 1 faces the hinge 2. One end of a chain 3b having an appropriate length is rotatably attached to the outer surface of the side member 1b via a metal fitting 3c.
The hook 3a and the chain 3b of the two holding frames 1 constitute a pair of connecting tools 3 that can be connected to and detached from each other, and by appropriately selecting a connecting position of the chain 3b with respect to the hook 3a, the connecting tool 3 The length of the frame is adjusted so that the winding diameter of both holding frames 1 can be adjusted, as will be described in detail later.
As will be described in detail later, a pair of holding protrusions 4 serving as temporary fixing means are provided on the inner surface side of the side member 1b on which the hook 3a is protruded, at a suitable distance in the longitudinal direction of the side member 1b. Has been established.
[0014]
Next, how to use this construction aid will be described.
For example, when the pipe P to be installed is an 8-inch pipe (outer diameter of about 206 mm), as shown in FIGS. 4 and 5, a heat insulating material A having a thickness of about 65 mm divided into two in the circumferential direction is used. The heat insulating material A is held on the inner surface sides of the two holding frames 1, respectively, and the rotation axis L of the two holding frames 1 is set along the longitudinal direction of the pipe P, and the holding of the chain 3b is held. The frame 1 is placed on the outer peripheral upper surface of the pipe P.
Then, the other holding frame 1 is suspended, but the suspended heat insulating material A comes into contact with the holding projection 4, so that the heat insulating material A is positioned at a predetermined position with respect to the holding frame 1. Retained securely.
[0015]
Next, the suspended holding frame 1 is rotated around the axis L and lifted (see FIG. 5), and both the holding frames 1 are wound around the outer circumference of the pipe P, and the chain 3b is connected to the hook 3a. Then, the two holding frames 1 are attached to the outer periphery of the pipe P.
At this time, the length of the connecting member 3 composed of the hook 3a and the chain 3b can be adjusted by selecting the connecting portion of the chain 3b to the hook 3a. Since the winding diameter of No. 1 can be adjusted, it is appropriately adjusted according to the diameter of the target pipe P and the thickness of the heat insulating material A.
As a result, as shown in FIG. 6, the two heat insulating materials A can be temporarily temporarily fixed to the outer periphery of the pipe P by the two holding frames 1. A binding material 5 made of an iron wire or a glass filament tape is wound around and firmly fixed and attached. For example, if the pipe P allows a low-temperature fluid to flow, polyurethane joints are formed between the heat insulating materials A. The joint material 6 such as a foam is injected, and the holding frame 1 is removed before or after the joint material 6 is injected.
[0016]
Thereafter, if necessary, another heat insulating material B is attached to the outer periphery of the heat insulating material A as shown in FIG. In other words, the heat insulating material A attached earlier is used as the heat insulating material on the inner layer side, and the heat insulating material B on the outer layer side is mounted outside the heat insulating material A. The heat insulating material B on the outer layer side has, for example, a thickness divided into two in the circumferential direction. A heat insulating material B of about 70 mm is used.
When attaching the heat insulating material B, the heat insulating material B is held on the inner surface sides of the both holding frames 1, one holding frame 1 is placed on the outer peripheral upper surface of the heat insulating material A, and the other holding frame 1 is The chain 3b is rotated around the center L, and the chain 3b is connected to and attached to the hook 3a.
At this time, in order to ensure the heat insulating effect, the joint between the outer heat insulating materials B is arranged so as not to overlap with the joint between the inner heat insulating materials A. The joint 5 is wound, and the joint material 6 is injected into joints between the heat insulating materials B, and the holding frame 1 is removed to complete the construction.
[0017]
[Another embodiment]
(1) In the above embodiment, an example was shown in which the two holding frames 1 formed in a semi-cylindrical shape were connected so as to be relatively rotatable around the axis L. However, as shown in FIG. A total of four holding frames 1 are connected to each other so as to be relatively rotatable around the axis L, and the inner surfaces of the holding frames 1 respectively hold the heat insulating materials A and B divided into four in the circumferential direction. Can also be configured.
In short, the number of divisions of the heat insulating materials A and B changes according to the diameter of the pipe P, and it is desirable to change the number of the holding frames 1 to be connected according to the number of divisions of the heat insulating materials A and B. If necessary, one holding frame 1 may hold two heat insulating materials A and B.
In addition, the example in which the inner heat insulating material A and the outer heat insulating material B are attached to the outer periphery of the pipe P in two layers has been described. However, when only one heat insulating material is attached and attached, three or more layers are attached. Is also applicable.
[0018]
(2) In the above embodiment, an example was shown in which each holding frame 1 was formed of a metal material. However, for example, the holding frame 1 may be formed of various synthetic resins such as plastic and FRP, as well as wooden glued laminated materials, ceramics, and the like. The specific configuration is not limited to that of a birdcage, and may be, for example, a curved solid plate.
The connecting tool 3 is not limited to the hook 3a and the chain 3b, but may be of various configurations such as a pair of hook-and-loop fasteners having an appropriate length. However, the present invention is not limited to the holding projection shown in the above embodiment, and may be made of, for example, a double-sided tape.
