Description

[Detailed explanation of the invention] This invention is suitable for areas where it is necessary to apply insulation materials on the inner and outer surfaces of pipes such as high-temperature heat exchangers, especially areas with high curvature, areas where thick insulation materials are applied in multiple layers, and spaces. This is related to a support device for insulation materials used in narrow spaces, etc., and can facilitate the work of applying insulation materials to the inside and outside surfaces of pipes, eliminate damage and deformation of materials during installation, and improve the degree of completion of the work. It is something.

It is difficult to apply heat insulating materials to the inner and outer surfaces of pipes such as high-temperature heat exchangers because the surfaces to be applied are not flat.

Particularly when the purpose is to insulate high-temperature areas, it is essential that the insulating material be strongly compressed and that there be no gaps or looseness.

Conventionally, the work of applying heat insulating materials, etc. has been carried out as shown in FIG. 1 AtB.

In other words, when placing a heat insulating material on the inner surface of the pipe a, pipes c and d of length corresponding to the thickness of the heat insulating material are installed on the inner surface of the pipe a, and then the heat insulating material is placed on the inner surface of the pipe a. After making a bolt hole e and passing a bolt cyd through the bolt hole e, place an insulating material holding plate f on the surface and temporarily fix it with a temporary fixing nut g, and in this way, apply the insulating material in an appropriate number of layers one after another. It was attached.

However, with this method, (1) Due to the curvature of pipe a, there is a difference between the upper distance The shape is oval, and therefore, after the heat insulating material is pasted, a gap is created, which deteriorates the heat insulating effect, and it is time-consuming and troublesome to fill the gap with filler.

(2) Since an oval hole must also be made in the heat insulating material holding plate f, sufficient temporary fixing cannot be performed.

(3) In order to attach the temporary fixing nut g, it is necessary to add water for the length of the bolt, resulting in poor work efficiency.

(4) Pole during work) Because c' and d protrude for a long time, it is difficult to work in a pipe with a narrow space, and efficiency is low.

It had some disadvantages such as:

The present invention relates to a support device for a heat insulating material that can eliminate the various problems mentioned above, and includes a bolt-like lower support formed by drilling a screw hole in the shaft center on one side of a bolt-like column. , a bolt-like middle support formed by drilling a threaded hole in the shaft core on the other side of a bolt-like column having a threaded portion on one side that is screwed into the threaded hole of the bolt-like lower support; The bolt-shaped upper support body is formed by providing a bolt-shaped pillar body with a threaded portion that is screwed into a screw hole of the bolt-shaped middle support body.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

The lower side of the bolt-like column of the required length is attached to the inside of the pipe, and a screw hole is bored in the upper shaft core to form the bolt-like lower support 1, and the diameter of the support 1 is A bolt-like middle support 2 is provided by providing screw holes on the lower side of the same bolt-like column in the shaft core part of the upper side to screw into the screw holes of the support 1.
A bolt-like upper support 3 is further formed by providing a threaded portion on the lower side of a bolt-like column having the same diameter as the support 2 to be threaded into a screw hole of the support 2.

Next, a case will be described in which three layers of heat insulating material are supported.

First, a bolt-shaped lower support 1 is installed inside the pipe 4, and the inner layer heat insulating material 5 and the pressing plate 6 on the surface thereof are supported by the lower support 1, and are temporarily tightened with nuts 7. do.

Next, the threaded end of the bolt-shaped middle support 2 is screwed into the screw hole of the bolt-shaped lower support 1 and firmly fixed, and a presser plate 9 is attached to the middle layer insulation material 8 and the surface thereof, respectively. 7. Support the body 2 and temporarily tighten the nut; Tighten to secure.

After that, the threaded end of the bolt-like upper support member 3 is screwed into the screw hole of the bolt-like middle support member 2 and firmly fixed, and the outer layer heat insulating material 10 and the retaining plate 11 are attached to the surface thereof, respectively. It is supported by the upper support body 3 and finally fixed by tightening with a nut 12.

Therefore, since there is almost no difference between the upper and lower parts of each support, it is possible to make holes in the insulation material with approximately the same size as the diameter of each support, and also to support each insulation material holding plate. It can be fitted into the body without any gaps, eliminates gaps and looseness, and eliminates the hassle of filling gaps 6.
Installation can be completed in a very short time using temporary nuts.

. Furthermore, by using a plurality of the above bolt-shaped middle supports 2, it is possible to support three or more layers of heat insulating material.

As described above, the insulating material support device of the present invention has a structure in which it is made into a bolt shape and is divided according to the number of layers of the insulating material, and the inside can be threaded to connect them one after another. (I) Since the length of the support is sufficiently short during the installation stage of each insulating material and this holding plate, the spacing between the supports is approximately the same on the top and bottom, allowing the insulating material to fit well into the support, which eliminates the gap created by conventional methods. This prevents the insulation from deteriorating due to the formation of gaps, and also eliminates the need to fill in gaps.

(Company) - It is sufficient to simply screw the temporary fixing nut onto the upper side of the support, which saves time and effort and improves work efficiency.

(1) The length can be adjusted by connecting the supports according to the work stage, so the space can be expanded and the work made easier. is never difficult.

(V) 4% & simple structure and easy to manufacture.
