Description

DETAILED DESCRIPTION OF THE INVENTION The present invention surrounds pipe piping with a layer of heat insulating material. This relates to pipe arrangement, snow insulation, and coating construction. In detail, the curved surface part of the pipe piping (the bent piping part, the two-branch distribution U part, the pulp storage area, the part where a curved surface is formed on the outer periphery of the heat material layer like a pipe) VC#, place 7ura material It concerns the coating of layers.

Is there an insulation effect on the pipes that pass hot water, cooling water, etc. per Vibe Distributor $ VC? For the purpose of making it durable, IfJi thermal materials such as hard cement and glass fibers are used.

There are good deeds such as rock wool, etc., but in order to make the outer peripheral surface of the 311 curved part into the desired shape with these publicly available heat-covered structures, it takes a professional day to use a trowel! There were many disadvantages in the 4-engine Fi technique, such as the need for techniques such as bracing and winding techniques for external panel tape, and mold growth on the surface of the outer sheath of the heat-generating material layer in the 2Ilii process. .

Present invention 11, in the conventional method, 6 above-mentioned drawbacks and 5-
Is there a humiliating technique in the surprising shape of the insulation material on the mouth? The purpose is to eliminate the need and speed up the work, reduce costs (formerly known as DI Eco Store), and reduce the amount of 3'-grown mold in 4 bags.

The outer frame is made of a curved and distorted material made of thin resin, with a part of the pipe having a male pipe attached to it in the longitudinal direction of the pipe.

(5) A method for covering a curved surface is provided.

Hereinafter, a description will be given based on the dog embodiment shown in the drawings.

Referring to FIG. 1, (1) is a pipe, (2) is a heat insulating layer, and (3) is a curved surface shaping material, which will be described later.

Next is curved surface shaping material (3)? explain.

Figure 2 shows the case of an elbow insulation structure used at a bend in the angle of view of a pipe, which has a similar shape to the right angle bend part (1)' of the pipe fi+, and the insulation layer (2) of the curved part to be constructed. It has a surface (5) of approximately the same shape as the surface shape, and both end faces (6
It is a thin synthetic resin product (for example, a blow-molded product with a thickness of 5 mm) with a Vc bottom molded with opening 61' and Vc analysis (7) in the longitudinal direction of the pipe and dividing the small diameter side into two.

In addition, a part of the curved surface shaping material + 31 tfi is cut in the longitudinal direction of the vibrator Vcl; 7J and is a thin-walled glass product, so it is deformable and can be easily deformed to enlarge the cut part.
ll k can be easily surrounded.

Next, the heat insulating material layer (2) is formed by forming a foamed synthetic resin Vc in the field foaming method according to the present invention. At this time, the above-mentioned curved surface shaping material (3) is used as the entire outer frame and Foamed synthetic resin according to the in-situ foaming method in the space between the insulation layer (2), the central pipe il+, and the outer frame curved surface shaping material +31? Inject and foam the space? It is filled with foamed synthetic resin to form a Vcll thermal material layer (2) between the curved elongated member (3), which is the outer frame, and the pipe (1).

In the above embodiment, an elbow for right-angle bending was explained, but curved parts (for example, 120°) other than 90° and other curved parts are also shaped into corresponding shapes, so the curved surface shaping material (3) is used. As an outer frame and exterior member, it can be easily formed into a predetermined shape, and is easy to construct.
So, hard cement? There is no need to apply hard cement or apply with a trowel like in the case of plastering! +
It can be installed even by experienced workers, and since no water is used, there is no need to worry about condensation or mold.

In the present invention, in accordance with the above-mentioned construction, a heat insulating material layer that surrounds the pipe is provided at the curved surface part of the pipe, and has a circumferential surface having a shape approximately equal to the outer shape of the heat insulating material layer, and both end faces are open. The outer frame is made of a thin synthetic resin curved material with a portion cut in the longitudinal direction of the pipe, and is filled with foamed synthetic resin to form a heat insulating layer on the curved surface. During the work, the curved surface shaping material serves as an outer frame for the on-site foaming of the foamed synthetic resin, and also serves as an exterior member to easily form a heat insulating layer, and eliminates the need for exterior work such as wrapping exterior tape. 1j rate of construction, IFjj construction time is shortened, and specialized construction techniques are not required, which has the effect of reducing construction costs.

In addition, since the construction is carried out without using water for cement and mortar work, construction (support) VC is required.
There is no occurrence of fungi, mold, etc. on the broken surface, and it is sometimes more effective than conventional methods on indoor fabrics.

Claims (1)

[Claims] When covering the circumference of a pipe with a heat insulating material layer (2), the circumferential surface has a shape approximately equal to the predetermined external shape of the curved surface of the heat insulating material layer (2), and both end faces (6) are open. After surrounding the outer periphery of the pipe (1) with a thin-walled synthetic resin curved shaping material (3) that is partially cut in the longitudinal direction of the pipe, a foamed synthetic resin is wrapped around the pipe (1) using the curved surface shaping material (3) as an outer frame. A method for covering a curved surface of a pipe with a heat insulating material layer, the method comprising forming a heat insulating layer on a curved surface of a pipe by foaming.
