Description

【発明の詳細な説明】 管側部の断熱方法 本発明は、管の分岐およびベンドの様な管側部の断熱方法に関する。[Detailed description of the invention] How to insulate the side of the pipe The present invention relates to a method of insulating pipe sides, such as pipe branches and bends.

断熱された管継手は、例えば第1図に示される態様において現在製造されている 。金属で通常作られる主管1は、剛性外側層と、発泡樹脂の軟質内側層とを通る 。次に、孔は、断熱層2の外装面に作られる。分岐管3は、該層に挿通され、主 管1の開口部の端縁に溶接される。次に、所定の長さの断熱層4,5.6は、分 岐管へ押込1れ、突合わせ溶接、ワイヤを使用する手溶接または可成的になった 材料の継目への添加により相互と、断熱層2とに結合される。この全体の操作は 、非常に時間が掛り、継目は、屡々完全に密封されず、これにより、水分は、発 泡用脂層−に後で浸入し得る。その上、発泡樹脂は、断熱層の端部て全く保護さ れず、従って、輸送中に損傷を受け得る。Insulated pipe fittings are currently manufactured, for example in the embodiment shown in FIG. . The main pipe 1, usually made of metal, passes through a rigid outer layer and a soft inner layer of foamed resin. . Next, holes are made in the exterior surface of the insulation layer 2. The branch pipe 3 is inserted through the layer and the main It is welded to the edge of the opening of the tube 1. Next, the insulation layer 4, 5.6 of a predetermined length is Pushed into the manifold, butt welded, hand welded using wire or formed The material is bonded to each other and to the insulation layer 2 by adding it to the seam. This whole operation is , which is very time consuming and the seams are often not completely sealed, which allows moisture to escape. The foam layer may later be penetrated. Moreover, the foamed resin provides no protection at all at the edges of the insulation layer. and therefore may be damaged during shipping.

本発明の目的「ハ、それによって作業が迅速に実施可能で、容易に自動比し得る と共に、耐水性製品が得られる管分岐および管ベンドの断熱方法を提供すること である。該方法は、管側部が、2型に収容され、該型0内側面が、該管側部の外 、側壁から所定の距離に配置され、該層の端部が、該管側部に対して横方向の要 素により該管側部に対して密封され、熱可塑性材料が、核層に装入され、該熱可 塑性材料が核層の内側面に沿って連続的な層を形成する如く、核層が、加熱され て運動状態に置かれ、核層が、連続的な熱可塑1生層の固fヒの原に除去され、 該層と管側部との間の空間が、断熱材料で充満されることを特徴とする。この様 にして、管側部、例えば管分岐は、連続的な剛性表面被覆およびその端部の剛性 被覆と、内側の発泡樹脂層とから成る断熱層を備えている。該方法は、主要部分 について自動塑造機で実施可能であり、その結果、細部の輸送中でも発泡樹脂に 水が侵入不能で、輸送中に発泡樹脂が損傷を受けない断熱が得られる。Objective of the present invention: ``C. Therefore, work can be performed quickly and automatic comparison can be easily performed. Also, to provide a method of insulating pipe branches and pipe bends that results in a water-resistant product. It is. In the method, the tube side is housed in a mold 2, and the inner surface of the mold 0 is the outer side of the tube side. , disposed at a predetermined distance from the side wall, the end of the layer being at a point transverse to the tube side. A thermoplastic material is charged into the core layer and the thermoplastic material is sealed against the tube side by a core layer. The core layer is heated such that the plastic material forms a continuous layer along the inner surface of the core layer. placed in a state of motion, the core layer is removed to a solid base of a continuous thermoplastic layer; It is characterized in that the space between the layer and the tube side is filled with an insulating material. Like this In addition, the tube sides, e.g. tube branches, have a continuous rigid surface coating and rigidity at their ends. It has a heat insulating layer consisting of a cover and an inner foamed resin layer. The main part of the method is can be carried out on automatic plastic molding machines, and as a result, the foamed resin remains intact even during transportation of details. The insulation is impenetrable to water and the foam is not damaged during transportation.

本発明の方法の好適な一実施例によると、型の端部に位置する密封要素は、管側 部に対する中心開口部を有する型の端部ケゞ−プルを備えている。端部ケゞ−プ ルが型と一体に作られるため、型と管側部とり〕間の空間・は、任意の別個の装 置で密封されなくてもよい。According to a preferred embodiment of the method of the invention, the sealing element located at the end of the mold is located on the tube side. It has an end capeple of the type having a central opening for the section. End cape Since the tube is made integrally with the mold, the space between the mold and the tube side holder is free from any separate equipment. It does not have to be sealed when placed.

本発明ノじ好適な第2実施列によると、好壕しぐは液体発泡材料を含有する断熱 材料は、固(ヒした熱可を上層つ外装面て作られる孔を介して、該層と管側部と 0間の空間に装入される。また、この手順は、容易に自動fヒ可能であり、これ (d、付加的な費用の節減を含む。According to a second preferred embodiment of the invention, the trench insulation includes a liquid foam material. The material connects the thermoplastic upper layer with the tube side through holes made in the outer surface of the upper layer. It is charged in the space between 0 and 0. Additionally, this procedure can be easily automated; (d. Includes additional cost savings.

言すれ1ばこの場合には金属管へ、断熱材料を付着させることは、屡々望ましい 。これ1は、熱可塑性層の形成中に管側部を冷却することによって可能IFなっ てもよく、これにより、熱可塑性材料は、型の加熱の際に金属管に付着しない。In other words, it is often desirable to attach an insulating material to the metal pipe in this case. . This 1 is possible by cooling the tube side during the formation of the thermoplastic layer. Optionally, the thermoplastic material does not stick to the metal tube during heating of the mold.

該冷却は、例えば、管側部に冷却媒体を送入するこ゛とによって行われてもよい 。The cooling may be carried out, for example, by introducing a cooling medium into the tube side. .
