た。 In pipeline piping work, conventionally, in order to insulate the pipe and the support, a stopper flange 2 protruding in a ring shape is provided around the pipe 1, as shown in Fig. , A support cover 3 having a U-shaped cross section is connected and fixed to the support body so as to cover the stopper flange 2 with an appropriate gap between the stopper flange 2 and the support cover 3. A structure was adopted in which the gap was filled with an insulating filler 4, the tube 1 was fixed together with the stopper flange 2 within the support cover 3, and the tube 1 was fixed to the support.

う欠点があつた。 However, since the filler material is easily compressed and deformed, and especially becomes fluid when the temperature rises, it is not possible to prevent the stopper flange from moving when the pipe expands in the axial direction due to temperature changes. The perf flange displaces the filler material and comes into contact with the support cover, resulting in a breakdown of the insulation between the tube and the support.

る。 The purpose of the present invention is to eliminate such drawbacks, and to provide an insulating fixing structure for a tube in which the insulation between the tube and the support is not destroyed even when the tube expands or contracts in the axial direction. It is something. That is, the present invention provides a ring-shaped stopper flange that protrudes around the pipe, and a U-shaped cross section is provided around the stopper flange with an appropriate gap between the stopper flange and the stopper flange. A support cover is provided, and in the gap between the side surface of the stopper flange and the inner surface of the support cover, multiple insulating members with high compressive strength are placed at appropriate intervals to surround the pipe, and the remaining gap is filled with insulating material. The main feature is that the stopper flange is fixed in the support cover together with the insulating member by filling the stopper flange with the filler material.
以下、本考案の一実施例を図面に基づいて説明

グする。 In FIGS. 2 and 3, 1 is a tube, and a ring-shaped stopper flange 2 is provided around the tube 1. The height and width of the stopper flange 2 are arbitrarily selected depending on the pipe diameter, wall thickness, and other conditions. The stopper flange 2 is attached by welding to a collar 5 attached to the pipe 1 by fillet welding.
The stopper flange 2, tube 1 and collar 5 are coated with a polyethylene coating 6 for insulation.

The structure of the support cover 3 may be divided into two or integrated. The support cover 3 is attached and fixed to the support base via a joint plate 7 and a fixing flange 8 with bolts and nuts or welding.

ることができる。 A plurality of insulating members 9 having high compressive strength are provided at appropriate intervals in the gap formed between the side surface of the stopper flange 2 and the inner surface of the support cover 3 so as to surround the pipe 1. The insulating member 9 is made of hard synthetic resin;
For example, phenolic resin can be used. In this case, if a heat-resistant synthetic resin is used as the insulating member 9, the pipe that transports the high-temperature fluid can be insulated and supported. The spacing between the insulating members 9 can be arbitrarily selected, but it should be at least as large as possible to fill the gap with the filler 4. Further, the insulating member 9 is arranged in a balanced manner so that pressure is evenly applied to each part of the support cover 3 and the stopper flange 2. The shape of the insulating member 9 may be any shape as long as it can insulate the stopper flange 2 and the support cover 3, and may be, for example, a substantially square prism.

脂を用いることができる。 Finally, the remaining gap occupied by the insulating member 9 is filled with an insulating filler 4,
The stopper flange 2 is fixed in the support cover 3 together with the insulating member 9. Note that in order to prevent the insulating member 9 from moving due to filling with the filler 4 and disrupting its balanced arrangement, the insulating member 9 is adhesively fixed to the side surface of the stopper flange 2 or the inner surface of the support cover 3 in advance. As the filler 4, epoxy resin can be used.

トツパーフランジの移動を阻止する。 In the pipe insulating fixing structure constructed in this way, when the pipe expands and contracts and a force that moves the stopper flange in the axial direction is applied, an insulating member with high compressive strength acts as an insulator in the support cover. prevents the stopper flange from moving.

ので品質管理が容易である。 As explained above, in the present invention, an insulating member with high compressive strength is provided in the gap between the side surface of the stopper flange and the inner surface of the support cover, so that even if the tube expands or contracts, the tube and support will not be connected to each other. The insulation will not be destroyed. Furthermore, since the insulating members are provided to surround the tube at appropriate intervals, the filling material can be easily and completely filled. Since the insulating member and the filler are combined, insulation can be maintained between the tube and the support cover, and flexibility can be provided to a certain extent. Incidentally, since the gap between the stopper flange and the support cover is completely filled with the filling material, there is no backlash and there is no need for waterproofing treatment. Furthermore, the support strength against external forces in the axial direction is high. Furthermore, since it is molded into a single piece in a factory, quality control is easy.
