The present invention relates to a spacer for a pipe cover which is installed to surround a pipe on the outer circumference of a pipe through which a fluid of high temperature flows, and more particularly to a spacer for a pipe cover which is provided on the outer circumference or inner circumference of a support band body made of a metal band, The gap maintaining sockets are provided radially with respect to the center of the pipe and both end portions of the support band main body are bent so as to abut against each other to constitute a space retaining band for the pipe cover so as to be joined by bolts, When the cover space holding member is provided so as to surround the outer periphery of the pipe, a space is maintained between the pipes and the pipe cover, which are respectively provided on the inner and outer rims of the present invention by a plurality of radially provided spacing holders. Compared with the conventional designs, it is possible to easily install spacing bands from small diameter (2 inches) piping to large diameter (30 inches) piping .

In general, when a high-temperature fluid flows inside a pipe, the high temperature of the fluid is conducted to the pipe, and the outer surface of the pipe becomes very hot. When the body comes into contact with the outer surface of the hot pipe, The piping cover is installed on the outer circumference of the pipe when the falling object falls into the pipe and the pipe may be damaged even if a high temperature fluid does not flow.

In view of the above problems, the conventional piping cover installed outside the piping is known to be registered in the Utility Model Registration No. 20-460483 (name of design: personal protection cover).

The above-mentioned conventional scheme is shown in Fig. 1, and the claim 1 is as follows.

That is, the claim 1 of the conventional design claims that a personal protection cover (not shown) for installing a supporter frame 1 outside the piping P and separating the cover member 5 from the piping P to the outside of the supporter frame 1 The supporter frame 1 is constituted by a concavo-convex shape in which the inner diameter portion 2 and the outer diameter portion 3 are alternately formed and the inner diameter portion 2 of the supporter frame 1 is provided with a pipe P, And the outer circumferential portion 3 is formed with a coupling portion 31 to which the cover member 5 is wound and coupled and both ends of the supporter frame 1 are engaged with the hook portions 71 The supporter frame 1 is connected to the connection portion 4 and the outer diameter portion 3 at both ends of the supporter frame 1 with the connection frame 7 formed with the supporter frame 1, A cover member (5) is wound around the outer diameter portion (3) of the supporter frame (1), and the cover member (5) It is characterized by constituting the sheet to each other, and the joint seam (51) being opposite ends are overlapped each other overlap bond.

Such a conventional design is such that when the band-shaped steel plate is continuously connected to the outer diameter portion 3 and the inner diameter portion 2 in a zigzag shape so as to be bent at a right angle and is wrapped around the pipe P, (1) is formed in a spline shape.

1 (B), when the supporter frame 1 formed in the shape of a spline is wrapped around the pipe P as shown in Fig. 1 (B), the support pipe portion 21 as a surface contacting the outer peripheral surface of the pipe P And the noncontact surface which does not contact the outer circumferential surface of the pipe P remains in the empty space 3a by the outer diameter portion 3 so that only a few of the contact portions 21 are in contact with the outer circumferential surface of the pipe P do.

In the case where a plurality of the contact portions 21 are disposed in contact with the outer circumferential surface of the pipe P in a dashed line so as to be in contact with the outer circumferential surface of the pipe P in such a manner that an external object hits the outside of the cover member 5, The cover member 5 including the supporter frame 1 is held by the gap P between the outer periphery of the pipe P and the outer periphery of the outer periphery of the pipe P, A problem is caused in that it is shaken from the outside.

For reference, the pipe P for installing such a pipe cover has a diameter ranging from 2 inches to 30 inches.

In this state, as shown in FIG. 1, the band-shaped iron plate is divided into a conventional supporter frame 1 in which the outer diameter portion 3 and the inner diameter portion 2 are bent in a right angle at a right angle, ) Has a problem in that it can not be applied to a small pipe having a diameter of 2 to 5 inches.

This is because, when the spline-shaped conventional design is installed in a pipe having a small diameter, the pipe tends to enter the open space 3a inside the outer diameter portion 3. As the inside of the outer diameter portion 3 is open, The inner space 3a of the outer diameter portion 3 is further widened so that the impact can not be properly supported.

In the pipe cover described above, the steel plate is cut to a width of about 5 centimeters and then subjected to primary working in a band shape. Thereafter, the metal band cut in the band shape is bent in a spline shape. Mm and the iron plate is cut into a band shape, it can be manufactured by bending a conventional design that can be installed in an 8-inch pipe.

Therefore, when it is desired to manufacture a conventional design to be installed in a pipe of 9 inches or more, there is a problem in that it is necessary to bend the metal band cut in a band shape by welding.

Further, there is a problem in that the operation of connecting the outer diameter portion 3 and the inner diameter portion 2 in a zigzag shape at right angles to each other is troublesome and the workability is deteriorated. Also, there is a problem in that, And a lot of logistics costs.
