Description

【０００１】
【発明の属する技術分野】
本発明は、配管と配管支持具との間に介在させる配管用保温材に関する。
【０００２】
【従来の技術】
配管を配管支持具によって支持する際に、両者の間に保温材を介在させることは広く行なわれている。
【０００３】
保温材として、合成樹脂発泡体で形成する構成、２分割タイプとし、両者の接合面に凹部及び凸部を形成して合体させる構成は、実開昭５６−１５８８３号、同５９−５６４７６号公報、特開平８−２７７９７０号公報、意匠登録第５４９２３９号公報などに記載されている。
【０００４】
【発明が解決しようとする課題】
上記したように、保温材を２分割タイプとし、両者の接合面に対称的な凹凸面を形成する構成は知られている。接合面の凹凸は保温材を円筒状に維持するのに有効であるが、従来の保温材の接合面凹凸は、上記した特開平８−２７７９７０号公報に示されているように、ストレートな凹条ないし凸条であるために、配管工事施工時にズレが生じたり、又は、正確に合体させた状態から配管の振動等によりズレが生じることがある。このような合体状態のズレを防止するには、保温材の外周に溝を設け、この溝の幅にぴったり合うようなバンドを持つ支持具を利用することが要求されるが、保温材外周の溝とバンドの幅が正確に一致しない場合には、保温材の合体状態にズレが生じる。
【０００５】
従来、保温材は上下で分割された形で配管に取り付けられる態様であったが、吊り下げ支持タイプの配管支持では、２つのバンド部のそれぞれに分割された保温材を予め仮止めしておくことが作業能率の向上に都合がよいが、従来タイプの接合面構造の保温材では、上下の位置に接合面が存在することとなる結果、保温材の接合面に結露が生じた場合、接合面に上記したズレが生じると、結露が容易に落下することになり、配管の防錆の点からも好ましくない。
【０００６】
本発明は、上記に鑑み、２分割タイプとし接合面に凹凸を設けて合体させる保温材において、合体状態にズレが生じることのない接合面構造を有する保温材を明らかにすることを課題とする。
【０００７】
【課題を解決するための手段】
本発明に係る配管用の保温材は、以下の構成を有する。
合成樹脂発泡体で２分割に形成した分割体の１対で構成される配管用支持金具の部分に使用される保温材において、
分割体のそれぞれの外周面には、配管用支持金具のバンドを装着する凹面部を形成すると共に、
２分割の分割体が１対に合体される各接合面には、凹部と凸部とで形成される係止機構が配置されており、
合体させた分割体が配管の長手方向にずれることが規制されている構造であり、
該合体させた分割体が配管の長手方向にずれることが規制されている構造が、下記［Ａ］構成であることを特徴とする配管用保温材。
［Ａ］
前記２分割の分割体の各々の周面端に位置する２つの接合面は、一方の分割体と他方の分割体とが相互に接合する平面状であり、
前記２つの接合面の各々には、該接合面の配管軸直交方向の中央部に前記凸部と凹部とが各１個ずつ配管軸方向の一端縁から他端縁まで直線状に、且つ連続して配置されており、
前記一方の接合面における凸部は、該平面状接合面の一端縁から中央まで凸状であり、前記一方の接合面における凹部は、該平面状接合面の他端縁から中央まで凹状であり、
前記他方の接合面における凸部は、該平面状接合面の他端縁から中央まで凸状であり、前記他方の接合面における凹部は、該平面状接合面の一端縁から中央まで凹状であり、
前記凸部は、該凸部の平面頂部に向かって次第に先細りとなるように相対向する傾斜面を有する山形形状であって、該山形形状とするための傾斜面が前記接合面に接する面側に相対向して設けられた形状であり、
前記凹部は、前記凸部の形状に対応する形状である構成。
【０００８】
【発明の実施の形態】
図１に示す実施例を説明する。この実施例の保温材１０は、配管用吊り金具などにより配管を天井などから懸架する場合に利用される。保温材１０は、ウレタン系の如き断熱性の合成樹脂発泡体で形成されており、同一形状のものを一対として合体させて利用する。接合面１１と１２のそれぞれには、凸部１３と凹部１４とから成る係止機構が相似形となるように配置されている。従って、分割された一対の保温材１０を合体させると、接合面１１と１２とでは、凸部１３と他方の分割体の凹部１４とが、凹部１４と他方の分割体の凸部１３とがそれぞれ嵌入し合うことになり分割体のそれぞれが矢符方向に移動することが規制される。
【０００９】
図示の実施例では、係止機構として凸部１３と凹部１４の２種類の組み合わせとした。
【００１０】
配管用吊り金具は、図示しないが、そのバンド部分が周面に施された凹面部１５に位置するよう配置される。本発明では、上記した係止機構により、合体された分割体が矢符方向に移動することがないので、配管用吊り金具のバンドの幅と凹面部１５の幅とに不一致があってもよい。
【００１１】
尚、配管用吊り金具のバンド部分（一対）に両面接着テープなどにより予め仮止めしておく態様では、接合面が図示の如き横方向でなく縦の方向となるようにそれぞれの分割体を配置する。
【００１２】
図２に示す実施例を説明する。この実施例の保温材１０は、据置型として支持バンドにより床面上に配管を支持する場合に利用される。保温材１０の構成は、一方の分割体の底部が床に設置する構造となっている点を除き、図１に示した実施例と同一である。
【００１３】
図３に示す実施例では、係止機構の凸部１３及び凹部１４の配置位置及び形状が他の実施例と異なる。
【００１４】
【発明の効果】
本発明に係る保温材によれば、合体させた保温材の分割体が、配管工事の際にも、或いは振動などにより位置ズレを発生することがなく、頭記した課題が解決される。

BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating material for piping interposed between a piping and a piping support.
[0002]
[Prior art]
When a pipe is supported by a pipe support, it is widely performed to interpose a heat insulating material between the two.
[0003]
As a heat insulating material, a structure formed of a synthetic resin foam, a two-part type, and a structure in which a concave portion and a convex portion are formed on the joint surface of the two and combined are disclosed in Japanese Utility Model Publication Nos. 56-15883 and 59-56476. JP-A-8-277970, design registration No. 549239, and the like.
[0004]
[Problems to be solved by the invention]
As described above, a configuration in which the heat insulating material is divided into two types and a symmetrical uneven surface is formed on the joint surface between the two is known. The unevenness of the joint surface is effective for maintaining the heat insulating material in a cylindrical shape, but the unevenness of the joint surface of the conventional heat insulating material is a straight concave as shown in the above-mentioned Japanese Patent Application Laid-Open No. 8-277970. Since it is a strip or a convex strip, a shift may occur during construction of the piping work, or a shift may occur due to vibration of the pipe from the state of being accurately combined. In order to prevent such a shift in the combined state, it is required to provide a groove on the outer periphery of the heat insulating material and use a support having a band that fits the width of the groove. When the width of the groove and the band does not exactly match, a deviation occurs in the combined state of the heat insulating material.
[0005]
Conventionally, the heat insulating material was attached to the pipe in the form of being divided into upper and lower parts, but in the suspension support type pipe support, the heat insulating material divided into each of the two band portions is temporarily fixed in advance. This is convenient for improving work efficiency, but in the case of a heat insulating material with a conventional type of bonding surface structure, if there is condensation on the bonding surface of the heat insulating material as a result of the presence of bonding surfaces at the upper and lower positions, the deviation described above to the surface occurs, it becomes a Turkey be easily fall condensation, undesirable from the viewpoint of the piping anticorrosive.
[0006]
This invention makes it a subject to clarify the heat insulating material which has a joint surface structure which does not produce a shift | offset | difference in a coalesced state in the heat insulating material which makes it a 2 division type and provides an unevenness | corrugation in a joint surface, and combines. .

The heat insulating material 10 is formed of a heat-insulating synthetic resin foam such as urethane, and is used by combining the same shape as a pair. On each of the joint surfaces 11 and 12, a locking mechanism composed of a convex portion 13 and a concave portion 14 is disposed so as to have a similar shape. Therefore, when the pair of divided heat insulating materials 10 are combined, at the joint surfaces 11 and 12, the convex portion 13 and the concave portion 14 of the other divided body become the concave portion 14 and the convex portion 13 of the other divided body.

[0011]
In addition, in the aspect in which the band part (a pair) of the pipe hanging bracket is temporarily fixed with a double-sided adhesive tape or the like, the respective divided bodies are arranged so that the joining surface is not in the horizontal direction as shown in the figure but in the vertical direction. To do.
