Description

Thermal insulation casing for pipes, construction method and manufacturing method

The present invention relates to a heat insulating casing for pipes, and more particularly, to a heat insulating casing which is used to insulate a pipe, and which is covered on the outside of the heat insulating material to protect the heat insulating material surrounding the outside of the pipe, and a construction method and a manufacturing method thereof.

In the case of a pipe in which a fluid, which is a hot or cold liquid or gas, flows through the pipe, preventing the heat of the fluid from flowing out through the wall of the pipe or preventing external heat from entering the inside of the pipe through the wall of the pipe. Keep the pipe warm. Insulating the pipe in this way can prevent the heat loss caused by the fluid flowing through the pipe.

In general, as shown in FIG. 1, the method of insulating a pipe is to cover the outside of the pipe with a heat insulating material, and then cover the outside of the heat insulating material with a cover made of a metal plate such as a galvanized steel sheet or a stainless steel plate to protect the heat insulating material. The method is used a lot. Among the materials used for thermal insulation of such pipes, a cover which is covered on the outside of the heat insulating material is called a thermal insulation casing (hereinafter referred to as "thermal insulation casing" in the present specification).

Normally, the thermal insulation casing of a pipe is made by rolling a metal plate in the form of a pipe. The length of the metal sheet is made in a length corresponding to the width of the metal plate to be used. It is constructed by connecting. To connect two adjacent insulation casings, one end of one insulation casing is inserted at one end of the other insulation casing so that the two insulation casings overlap each other, and the overlapped portions are banded together to bind or screwed together. The method of connection is used.

As described above, the method of tying the overlapped portion with a band or fastening screws by the method of connecting the thermal insulation casing has a problem in connecting the thermal insulation casing because the insulation material inside the thermal insulation casing is very soft. That is, in the case of binding with a band, since the insulating material is a soft material, the two insulating casings are not firmly bound, and in some cases, the connection part of the two insulating casings falls out when a vibration occurs in the pipe or an impact caused by a water hammer. In addition, the screw fastening method is a very soft material insulated inside the insulating casing, and the wall of the insulating casing is very thin, so that the screw cannot penetrate the surface of the two-layer insulating casing, and it is excessively excessive. If you try to tighten the screw by force, not only the work is difficult, but also the wall of the thermal insulation casing locally there is a problem that aesthetic appearance worsens.

On the other hand, in the prior art for the insulating casing, Republic of Korea Utility Model No. 20-0207805 "duct for pipe insulation material" to form a coupling groove 11 in one inner wall of the plate cut in accordance with the standard of the heat insulating material 60, The other end portion is formed of a duct plate member 10 formed with a coupling portion 12 is inserted into the coupling groove 11, the fastening ring 31 and the fastener 32 and the like to be mutually insulated (60) A duct for a pipe insulator is disclosed, which is composed of a strap means 30 that binds the duct plate 10 to be held. However, this is different from the present invention in that a separate strap means is provided.

In addition, the Republic of Korea Utility Model Registration No. 20-0390732 "pipe casing" in the pipe casing for wrapping and fixing the insulation for protecting the internal pipe, the body 11 formed by bending a metal plate in the form of a cylinder; A first coupling part 12a configured to bend one end of the body 11; The second casing portion (12b) is formed by bending the other end of the body 11 is fitted to be coupled to the first coupling portion (12a); pipe casing characterized in that the configuration is configured.

As shown in FIG. 4 of the present invention, the female joint 2 of the present invention is a hook 21 and the hook 21 formed by bending so that one end of the body (1) "S" Including an engaging jaw 22 formed at predetermined intervals inside the, and the male joint 3 is inserted into the insertion portion 31 and the insertion formed by bending so that the other end of the body 1 is "b" It includes a locking projection 32 formed in the portion 31 at a predetermined interval.

Therefore, when the inserting portion 31 of the male joint 3 is inserted into the engaging seat 21 of the female joint 2, the locking member of the male joint 3 is inserted into the latching jaw 22 of the female joint 2. The group 32 is caught, and the female joint 2 and the male joint 3 are fastened to each other to form a joint J. At this time, since the male joint 3 is bent by the letter “b”, when the female joint 2 and the male joint 3 are coupled to each other and joined, the heights of both sides of the joint J are the same, so that the step in the joint J is different. Does not occur.

As described above, the present invention forms a joint J by inserting the male joint 3 into the female joint 2 and fastening each other, so that the heat insulating material wraps the insulating casing of the present invention without a separate fastener such as a screw or rivet. It can be conveniently installed in a duct.

In addition, it is more preferable that the male joint 3 of the present invention is formed with a bent portion 33 extending from the locking projection 32 and bent inwardly. The bent part 33 makes it easier to insert the insertion part 31 of the male joint 3 into the engaging seat 21 of the female joint 2.

The first coupling protrusion 4 of the present invention extends in the circumferential direction on the upper end of the body 1, and is formed by mounting and rotating both ends of the body 1 on the roller for forming the protrusion.

The second coupling protrusion 5 of the present invention extends in the circumferential direction at the lower end of the body 1 and is formed in the same manner as the first coupling protrusion 4.

At this time, the protrusion of the second coupling protrusion 5 is formed larger than the protrusion of the first coupling protrusion (4). Therefore, as shown in FIG. 6, when the upper end of one insulating casing is inserted into the lower end of the other insulating casing and a force is applied, the first coupling protrusion 4 of one thermal insulating casing is connected to the other of the thermal insulating casing. The insulating casing of the present invention is very simply and firmly connected while overlapping the second coupling protrusion 5.
