Description

  The present invention relates to a pipe support and a pad used therefor.

For example, ducts and piping for indoor air conditioning are laid on the ceiling of buildings such as office buildings and factories. As a support for this pipe, the one shown in FIG. 21 has been proposed. The support 51 is attached to a bolt 52 disposed on the back of the ceiling. The support 51 includes a U-shaped support 51a when viewed from the piping direction. The support 51a supports a thick heat retaining layer S having a relatively low thickness and made of a foamed resin coated on the outer periphery of the pipe P. (See Patent Document 1)
Also, there is a pipe support fitting described in Patent Document 2. As shown in FIG. 22, the pipe support fitting 53 is formed by projecting and forming a support portion 54a of the pipe P of the support fitting main body 54 that can be plastically deformed in the pipe direction, thereby increasing the support area of the heat insulating layer S. The load due to the weight of the piping P acting on the surface of the heat insulating layer S is reduced so that the heat insulating layer S is not crushed.

  However, the former support tool has the following problems because the width of the support portion 51a that supports the heat insulating layer S of the pipe P is narrow. That is, when the heat insulating layer S is supported by the support portion 51a having a small area, the heat insulating layer S is compressed by the weight of the pipe P and the heat insulating layer S and the weight of liquid such as hot water or cooling water in the pipe P. The reaction force of the load acts in the direction to do. As a result, there is a problem that the heat insulating layer S is crushed and thinned, the heat insulating effect of the heat insulating layer S is reduced, and the heating efficiency or the cooling efficiency of the air conditioner is reduced. In addition, the thinning of the heat insulating layer S makes it easy for condensation to form on the surface of the heat insulating layer S. When water drops are dropped on the back surface of the ceiling wall due to this condensation, the ceiling wall becomes stained or corrodes the ceiling wall. There was a problem of letting.

  On the other hand, in the latter support fitting 53 for piping, since the support portion 54a is projected in the piping direction, the support area of the heat insulating layer S is widened, and the heat insulating layer S is caused by reaction force due to its own weight of the piping P or the like. The function of the heat insulation layer S is maintained appropriately without being compressed. However, since the support portion 54a is formed so as to overhang the lower portion of the support bracket main body 54, if the support bracket main body 54 is press-molded with a metal plate having the same thickness, the area of the waste material is increased, resulting in a material cost. There was a problem that it was not possible to reduce.

You may make it do. In this embodiment, the holding part 37b is elastically deformed as indicated by a two-dot chain line in FIG. 16 to enlarge the groove 37a, whereby the holding part 37b is provided at both ends of the main body 22 in the piping direction X. The buffer layer 37 can be detachably mounted from the main body 22, and the buffer layer 37 can be easily replaced.

  As shown in FIG. 17, both end portions of the buffer layer 37 in the width direction Y orthogonal to the piping direction X are buffered so as to correspond to the side plates 12b and 12g of the support body 12 in the use state shown in FIG. The sheet portion 38 may be integrally connected so as to be oriented in the width direction Y. In this embodiment, as shown in FIG. 18, when the pipe P is supported in two upper and lower stages, the buffer sheet portion 38 is on the heat insulating layer S of the upper pipe P, and the tip portions of the buffer sheet portion 38 are close to each other. Thus, since the heat insulation layer S of the upper pipe P does not directly touch the side plates 12b, 12g, the connection ring 14 and the like, the support state of the heat insulation layer S is further stabilized, and the upper pipe Deterioration of the P heat insulating layer S can be suppressed. Although not shown, the heat insulating layer S of the pipe P may be covered so that the tip portions of the buffer sheet portions 38 overlap each other.
