  By the way, when the duct is used, the duct vibrates in small increments due to the passage of the gas in the duct, and when this occurs over time, the duct may deviate from the holding position by the hanging band that was originally attached, and may “displace”. As the “displacement” of the duct progresses, the suspension pitch becomes biased, and the portion where the suspension pitch of the duct becomes large sinks downward due to the load, and the friction of ventilation may increase.

  In this regard, in the invention described in Patent Document 1, a belt-shaped member having a base material made of polyester cloth and coated with polyvinyl chloride on both front and back surfaces is used.

  In view of the above-described problems of the prior art, it is an object of the present invention to prevent the duct from being displaced from the holding position of the suspension band due to vibration generated in the duct when the duct is used.

  The device according to claim 1, which achieves the above object, is a suspension band for holding a duct by wrapping a resin-made band-shaped main body bent in a longitudinal direction and covering the entire length of the main body in the longitudinal direction.

  According to a fourth aspect of the present invention, the opening line is provided with a plurality of holes having at least one of an opening area and an opening shape, which are repeatedly arranged in the longitudinal direction at predetermined intervals.

  According to the first aspect of the invention, when the duct is suspended, the protective sheet is peeled off and the duct is attached to the exposed adhesive surface of the double-sided tape, so that the duct can be firmly held. The displacement of the duct due to the vibration of the duct can be prevented.

  The invention according to claim 2 relates to a specific structure of the double-sided tape. According to the second aspect of the present invention, the duct can be bonded and held at two places in the longitudinal direction of the duct, which is the width direction of the main body, and the displacement of the duct can be prevented stably.

  The invention described in claim 3 relates to a specific structure of the double-sided tape. According to the invention described in claim 3, even if the width of the main body is narrow, it is possible to provide a double-sided tape having a width sufficient to hold the duct and a hole having a dimension sufficient to fix the structure to the support member. it can.

  The invention described in claim 4 relates to a specific structure of the aperture line. According to the invention described in claim 4, holes corresponding to the support member and the duct can be selectively used.

  Hereinafter, embodiments of a hanging band according to the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 3, the suspension band 1 of the present embodiment suspends a support member 91 from a structure 9 such as a ceiling in a structure, particularly in an air-conditioning room, and the support member 91 includes a bolt, a washer, and a nut. A portion (fixed portion 13) where the main body 2 is bent and pasted is fixed by the fixing member 44, and the duct 8 is suspended and held.

  As shown in FIG. 1, the suspension band 1 of the first embodiment is made of resin and has a long band-like (rectangular) main body 2, and an opening line 4 formed at the center in the width direction of the main body 2, It consists of adhesive lines 3 and 3 arranged at the upper and lower ends excluding the center in the width direction of the main body 2.

  The suspension band 1 is formed by continuously molding the band-shaped main body 2 and is used by cutting it to a predetermined length when in use. This length is obtained by bending the suspension band 1 and suspending the suspension band 1 in the circumferential direction of the duct 8, connecting both ends in the longitudinal direction and suspending the suspension band 1.

  In the opening line 4 of the main body 2, a plurality of holes 41, 42, and 43 having different opening areas and opening shapes are provided at regular intervals over the entire length in the longitudinal direction of the main body 2 by repeating a predetermined arrangement. In the present embodiment, the first hole 41 having a regular pentagon, the second hole 42 having a regular pentagon but having a smaller opening area than the first hole 41, and the round hole having an opening area larger than that of the second hole 42. Small third holes 43 are successively formed.

  The 1st hole 41 and the 2nd hole 42 are opened to a regular pentagon, and the fixing member 44 (refer FIG. 3) used is a thing with a volt | bolt, a washer, and a nut. The third hole 43 opens in a circular shape, and the fixing member 44 is a screw. These are provided over the entire length in the longitudinal direction of the main body 2 by repeating the arrangement order of the first hole 41, the third hole 43, the second hole 42, and the third hole 43.

  The adhesive layers 3 and 3 are provided over the entire length in the longitudinal direction of the main body 2 at both the upper and lower ends in the width direction in FIG. As shown in FIG. 2, the adhesive layers 3 and 3 have a two-layer structure of double-sided tapes 31 and 31 and protective sheets 32 and 32. Thus, by making the bonding lines 3 and 3 have a two-layer structure, the protective sheets 32 and 32 can be removed and the duct 8 and the main body 2 can be bonded.

  That is, as shown in FIG. 3, when the suspension band 1 is used, the duct 8 is suspended and held by bending the main body 2 and disposing the duct 8 on the inner peripheral side. At this time, an adhesive portion 11 where the surface of the duct 8 contacts the main body 2 of the suspension band 1 and a non-adhesive portion 12 where the surface of the duct 8 does not contact the main body 2 are formed. It is preferable that the protective sheets 32 and 32 are peeled off from the double-sided tapes 31 and 31 only on the contact portion 11 and adhered to the duct 8.

  On the other hand, when the non-adhesive portion 12 is forcibly attached to the duct 8, the surface of the duct 8 may be peeled off due to the vibration of the duct 8. is not. Therefore, the adhesive portion 11 and the non-adhesive portion 12 are appropriately determined based on the use length of each cut suspension band 1 and the diameter of the duct 8, and the protective sheets 32 and 32 are not removed from the non-adhesive portion 12. It is preferable to put in. In addition, it is easier in terms of construction to peel off all the protective sheets 32 and 32 and to adhere only the contact portion 11 to the duct 8.

  As shown in FIG. 3, a portion where the main body 2 is bent and the both end portions in the longitudinal direction of the main body 2 face each other and overlap is defined as a fixed portion 13. At this time, the both ends of the main body 2 are overlapped with at least one hole having the same diameter (for example, holes 41, 41) communicating with each other. The fixed portion 13 further fixes the hole of the support member 91 to the two holes having the same diameter that are communicated with each other, and the fixing member 44 is inserted and clamped / fixed to the holes so that the duct 8 is fixed to the support member 91.・ We support.

  Even if the duct 8 vibrates, the suspension band 1 can prevent the slackness of the duct 8 due to the slippage. Furthermore, by providing the double-sided tapes 31 and 31 on both outer sides, the duct 8 can be bonded and held at two places in the longitudinal direction of the duct 8 which is the width direction of the main body 2, and the duct 8 can be prevented from being displaced stably. it can.

  It is preferable that the hanging band 1 also peels off the protective sheets 32 and 32 from the double-sided tapes 31 and 31 positioned at both ends of the main body 2 facing each other. In this case, both ends of the main body 2 can be bonded and held together by the double-sided tapes 31 and 31 and fixed by the fixing member 44. Since the suspension band 1 is provided with a plurality of different holes 41, 42, 43, the holes 41, 42, 43 (fixing member 44) corresponding to the support member 91, the duct 8, and the like can be selectively used.

  In the suspension band 1 before use, such as during storage, the adhesive surface can be protected by the protective sheets 32, 32, thereby preventing a decrease in adhesive strength. Furthermore, it can be stored in a compact state such as being rolled. Thus, even if it stores in the state which accumulated other parts on double-sided tape 31 and 31 by winding in roll shape etc., there is little resistance of the part piled up by protection sheets 32 and 32, and suspension band 1 of desired length Can be pulled out (taken out) easily.

  Moreover, the suspension band 1 forms the main body 2 by, for example, extrusion molding, affixes double-sided tapes 31 and 31 to one plane of the main body 2, and forms a plurality of holes 41, 42, 43 by drilling the main body 2. It is preferable to manufacture by providing. The suspension band 1 may be fixed by overlapping one end portion in the longitudinal direction of the main body 2 in front of the other end portion in the longitudinal direction, and the other end portion may be the fixed portion 13.

  As shown in FIG. 4, the suspension band 1 of the second embodiment has an adhesive line 3 formed of a double-sided tape 31 and a protective tape 32 at the center in the width direction of the main body 2, and overlaps with the opening line 4. It is formed. The suspension band 1 can adhere and hold the duct 8 by the double-sided tapes 31, 31, and can prevent the duct 8 from shifting. At this time, both sides of the overlapping adhesive line 3 and aperture line 4 in the center in the width direction are ordinary resin belts.

  The suspension band 1 according to the second embodiment is preferably used for a suspension band having a smaller dimension in the width direction than the suspension band 1 according to the first embodiment.
