JPS5811983Y2 - metal pipe band - Google Patents

Description

[Detailed description of the invention] The present invention is based on a metal pipe band, in which a pair of semi-circular pieces are connected at one end so as to be openable and closable, and a pipe is inserted into the gap between the pieces and the other end is connected to a pair of external support pieces. This is an improved version of the usual pipe band, which clamps the pipe by inserting a bolt and tightening a nut, and suspends the pipe from, for example, the ceiling.

That is, by applying a coating made of a material such as synthetic resin that is elastic but also resistant to galvanic corrosion to the connecting part of the semi-annular pieces and the succeeding semi-annular piece, both semi-annular pieces are forcibly opened. Although it can be opened and closed freely, it is prevented from opening and closing freely, making it easier to handle during work, making it easier to manufacture than the conventional semi-annular piece in which rubber is fitted on the inner surface, and sufficiently preventing galvanic corrosion. Specific examples thereof are detailed below with reference to the drawings.

Reference numerals 1a and 1b are a pair of metal semi-circular pieces, which are arcuate in the illustrated example, but may also be rectangular.

Reference numeral 2 denotes a connecting portion which connects both semi-annular pieces 1a and 1b at each end so as to be openable and closable.In the drawing, it is in the form of a hinge with a shaft 3, but other connecting structures can also be adopted.

4a and 4b are supporting pieces, and the semicircular pieces 1a and 1 are the same.
Through holes 7a and 7b protrude outward at the other end of b, through which the bolt 5 is inserted and supported and tightened with the nut 6.
is worn.

Reference numeral 8 denotes a coating made of a material such as synthetic resin that is elastic and resistant to electrolytic corrosion.

This covering 8 covers the connecting portion 2 and further covers the semicircular pieces 1a and 1.
It covers part or all of b.

As shown by the two-dot chain line in Fig. 1, the connecting part 2 can be rotated if forced force is applied by hand.
Normal free movement as shown by the chain three-dot line in the figure is prevented.

Therefore, the coating 8 is applied to the connecting portion 2 with the supporting pieces 4a and 4b close together.

In addition, for the semi-annular pieces 1a and 1b, these are connected to the pipe P.
Avoid direct contact with pipe P to prevent electrolytic corrosion, etc.
absorb vibrations.

As a method for applying the coating 8, a dipping method, a tube heat shrinking method, etc. can be adopted, and processing can be performed easily.

The illustrated band forcibly opens the semi-annular pieces 1a and 1b and fits them into the pipe P. Then, as usual, tighten the support pieces 4a and 4b with bolts and nuts 5 and 6 via a hanger, etc. The pipe P can be supported by attaching it to the ceiling or the like.

Since the pipe P does not come into direct contact with the semi-annular pieces 1a and 1b and is covered by the coating 8, it is not affected by electrolytic corrosion or the like.

According to the present invention, an elastic and corrosion-resistant coating that tends to prevent free movement of the connecting portions is applied to the connecting portions of the pair of semi-annular pieces and the portions following the connecting portions, so that the semi-annular pieces can freely sway relative to each other. Bolts and nuts can be attached to pipes with one hand or both hands, and there is no need to hold the bolts and nuts in place with both hands, unlike conventional methods. It has various effects, such as being easy to apply, preventing galvanic corrosion, and being able to apply the coating itself easily.
