Abstract

PURPOSE: To provide a heat insulating material, which can be prevented from dropping from a pipe when a supporting hand is removed after installation of the heat insulating material to the pipe and can be temporarily locked, by dividing a ring-type heat insulating material, which can be fitted around the pipe, into two insulating pieces and integrally forming fixing parts, which are engaged with the joint faces of facing heat insulating piece, on left and right joint faces in the heat insulating pieces. CONSTITUTION: A heat insulating material main body 1, which is made of foam rubber or synthetic resin and is formed into a ring, is equally divided into heat insulating pieces 2, 12. On one side of joint faces 4, 4 in one heat insulating piece 2, a dovetail mortise type recessed groove 5a is formed parallelly to the longitudinal direction of a pipe, while on the other side, a projection piece 5b to be slid in the recessed groove 5a is formed. In the other heat insulating piece 12, a recessed groove 15a and a projection piece 15b are arranged on joint faces 14, 14 individually in the same way. In usage, the heat insulating pieces 2, 12 are arranged while setting the recessed grooves 5a, 15a and the projection pieces 5b, 15b face to face and is slid laterally along the outer circumference of the pipe so as to be temporarily locked, and then, a pipe supporting metal fitting is installed around the heat insulating pieces 2, 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe support metal fitting for suspending pipes at appropriate intervals when it is necessary to keep warm such as liquefied gas pipes, cold / hot water pipes, refrigerant pipes, steam pipes, etc. The present invention relates to a heat insulating material used by being interposed between a pipe and a pipe.

[0002]

2. Description of the Related Art Conventionally, as a heat insulating material, a body made of foam rubber or a synthetic resin, which is formed into a ring-shaped main body having a hollow portion into which a pipe is fitted in the center, is used in combination. However, the mounting method is as follows: Insulate the heat insulation pieces by hand so that the inner wall of the hollow part becomes a ring shape where the inner wall of the hollow part fits in the pipe at the appropriate place of the pipe, and while keeping this state, the band of the pipe support fitting The part of was attached from above the heat insulation piece, and the band was tightened and fixed with the bolt that supports the tan buckle.

[0003]

In the above conventional method,
Since the two heat insulating pieces are combined by hand and the pipe support fitting is attached from above the heat insulating piece while maintaining the state, there is a problem that the work is very troublesome, laborious, and work efficiency is deteriorated.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to keep a heat insulating material along a pipe and not to remove it from the pipe even if a hand is released. It is intended to provide a heat insulating material that can be temporarily fixed.

As a means for this, a ring-shaped heat insulating material body having an inner wall surface fitted along the outer periphery of the pipe is divided,
It is characterized in that the left and right joint surfaces of the divided heat retaining piece are integrally formed with fixing portions that engage and fix the joint surface of another heat retaining piece.

With the above structure, since the fixing portions for engaging and fixing the joint surface of another heat insulating piece are integrally formed on the left and right joint surfaces of the divided heat insulating piece, the heat insulating material is attached along the pipe. After that, even if the user releases the hand, it is possible to temporarily fix the pipe without coming off from the pipe.

1 is a perspective view showing a first embodiment of the present invention, and FIG. 2 is a sectional view showing a first embodiment of the present invention. Reference numeral 1 is a heat insulating material body, which is formed of foamed rubber or synthetic resin in a ring shape, and 2 and 12 are heat insulating material bodies which are equally divided. The ratio of division is preferably equal, but not limited to this. Three
Is an inner wall surface fitted along the outer circumference of the pipe, and 4 and 4 are joint surfaces. A dovetail-shaped groove 5a is formed on one of the joint surfaces 4, 4 so as to be parallel along the longitudinal direction of the pipe, and the bottom of the groove cross section is longer than the opening, and the other groove 5a is formed. In order to be slidable, a projecting piece 5b whose cross section is longer at the tip end than at the base end is formed. Similarly, the other heat retaining piece 12 also has a groove 15a and a protruding piece 15b formed on the joint surfaces 14 and 14, respectively.

As shown in FIG. 3, concave grooves 25a, 25a
The protruding pieces 25b, 25b are, for example, one heat retaining piece 22.
Concave grooves 25a, 25a on the joint surfaces 24, 24 of the same, and projecting pieces 25b, 25 on the joint surfaces 34, 34 of the other heat retaining piece 32.
b may be formed. Further, the combination of the concave groove and the protruding piece is not limited to the dovetail groove shape, and for example, a hook shape or an arrow shape can be easily considered.

FIG. 4 is a perspective view showing a second embodiment of the present invention, and FIG. 5 is a sectional view showing a second embodiment of the present invention. Similar to the first embodiment, the heat retaining pieces 102 and 112 are formed, the concave portion 105b is formed on one of the joint surfaces 104 and 104, and the convex piece 105b that can be fitted into the concave portion 105b is formed on the other side. Similarly, another heat insulating piece 112 has concave portions 115a and convex pieces 11 on the joint surfaces 114, 114, respectively.
5b is formed. Also in the second embodiment, similarly to the first embodiment, only the concave portions may be formed on both joint surfaces of one heat retaining piece, and only the convex pieces may be formed on both joint surfaces of the other heat retaining piece.

FIG. 6 is an explanatory view showing a usage state of the first embodiment of the present invention, in which the heat insulating piece 2 is provided along the outer circumference of the pipe A,
12 is arranged in the concave grooves 5a, 15a so that the projecting pieces 5b, 15b face each other, and slides left and right to be temporarily fixed, and then,
Attach the pipe support bracket B from above the heat insulating materials 2 and 12.

15b are arranged so as to face each other, and the convex pieces 15b and 115b are pushed vertically or horizontally to temporarily fix them.
Then, the pipe support fitting B is attached from above the heat insulating materials 102 and 112.

[0012]

As described in detail above, according to the heat insulating material for piping equipment of the present invention, the fixed joints on the left and right joint surfaces of the divided heat retaining piece are engaged with and fixed to the joint surface of another heat retaining piece. Since the parts are formed integrally, after attaching the heat insulating material along the pipe, you can temporarily fix it without removing it from the pipe even if you release your hand, and you can easily install the pipe support bracket with both hands,
Moreover, it is possible to obtain a heat insulating material for piping equipment which is practically useful such as higher safety.
