JP3046456U - Insulation protective cover - Google Patents

Abstract

(57) [Problem] To provide a protective cover which is thin but has high rigidity. SOLUTION: The protective cover (elbow cover 1) is constituted by a corrugated rigid plate in which a plurality of stripe grooves 10 are formed on the entire surface of the plate material. It is repeated at a distance of 3 mm and a groove interval of about 4 mm.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a protective cover for a heat insulating material represented by an elbow cover, a racking cover, a flange cover, and the like.

[0002]

[Prior art]

 Pipes that require heat insulation such as cold and hot water are covered with a heat insulating material and a protective cover is attached to the heat insulating material. If the piping is installed outdoors, the protective cover is made of a metal plate such as a galvanized iron plate, a color iron plate, a stainless steel plate, or an aluminum plate. Since the protective cover is made of the above-mentioned plate material, it has excellent corrosion resistance and can be used for a long period of time.However, carelessness is required because the cover itself is a thin plate and the heat insulating material inside is flexible. When the cover is pressed, the pressed part easily dents. For this reason, the applied protective cover was often left in irregular shapes everywhere, and the appearance was poor.

[0003]

[Problems to be solved by the invention]

 The problem to be solved by the present invention is to provide a protective cover that is thin but has high rigidity.

[0004]

[Means for Solving the Problems]

 The solution is characterized in that the protective cover is constituted by a corrugated steel sheet in which a plurality of stripe-shaped grooves are formed on the entire surface of the plate material. The corrugated steel sheet has a thickness of 0.3 mm and a groove interval of 4 mm. It is repeated on the order of millimeters.

[0005]

[Embodiment of the invention]

 1 and 2 show an elbow cover, and FIG. 3 shows an example of a pipe.

In FIG. 3, 1 denotes an elbow cover, 2 denotes a racking cover, and 3 denotes a flange cover, which are attached to a heat insulating material 5 covered on a tube 4. The flange cover 3 is applied to a portion of the pipe provided with a heat insulating material at a part of the pipe where the pipe is connected in the middle of the pipe, and is larger than the racking cover 2 by an amount corresponding to the outer diameter of the flange. The diameter is formed.

In FIGS. 1 and 2, the elbow cover 1 is a corrugated steel sheet having a plurality of strip grooves 10 formed on the entire surface of the sheet material. Specifically, a stainless steel sheet having a thickness of 0.3 mm is used. In addition, a steel sheet is used in which the interval between the streak grooves 10 is repeated at about 4 mm.

The elbow cover 1 is composed of a body 1a and a fastening portion 1b, and the fastening portion 1b is attached to the inside of a portion where the tube 4 is bent at a right angle. Although the direction of the groove 10 is different between the body 1a and the fastening portion 1b, the direction of the groove of the groove 10 is not particularly limited.

The racking cover 2 and the flange cover 3 also use the same plate material as the elbow cover 1.

Although not shown in FIG. 3, the protective cover includes a valve cover and the like in addition to the above.

[0011]

[Effect of the invention]

 Since the protective cover of the present invention is made of a corrugated steel sheet with streak grooves formed on the entire surface of the sheet material, the strength of the steel sheet itself is increased, and there is no danger of being easily dented just by pressing the cover surface. Therefore, it has the effect of maintaining the beauty during construction for a long time.
