Description

  The present invention has a pipe support structure, and in particular, has a first holding part and a second holding part that are halved having an inner peripheral surface that follows the peripheral surface of the pipe and are connected to each other via a hinge so as to be able to rotate. The suspension member includes an anti-vibration rubber covering the inner peripheral surface of the first holding portion and the inner peripheral surface of the second holding portion of the suspension member, and the first holding portion and the second holding portion via the anti-vibration rubber. The present invention relates to a pipe support structure for holding a pipe and supporting the pipe by suspending it from the ceiling.

  When a pipe arranged in a building, for example, a pipe of an air conditioner is hung and arranged in a building, a pipe support structure that supports the pipe by hanging from the ceiling is used. (For example, refer to Patent Document 1). An outline of this type of pipe support structure will be described with reference to FIG.

  As shown in the figure, the pipe support structure 100 includes a metal suspension member 110 that suspends the pipe 1 from the ceiling, and an anti-vibration rubber 120-attached to the peripheral surface 1 a of the pipe 1 by being attached to the suspension member 110. 1 and 120-2 are provided as main components.

  The suspension member 110 includes a holding portion 113 attached to a suspension portion 111 attached to a ceiling of a building (not shown) with bolts 112. The holding unit 113 is in a half-shape having a first holding unit 113-1 and a second holding unit 113-2, and the first holding unit 113-1 and the second holding unit 113-2 are hinged. The components are connected to each other via 114.

  Each of the first holding unit 113-1 and the second holding unit 113-2 has an inner peripheral surface 113a that follows the peripheral surface 1a of the pipe 1, and covers the inner peripheral surface 113a of the first holding unit 113-1. The anti-vibration rubber 120-1 is attached as described above, and the anti-vibration rubber 120-2 is attached so as to cover the inner peripheral surface 113a of the second holding portion 113-2.

  Each of the pair of anti-vibration rubbers 120-1 and 120-2 has an inner peripheral surface 120a along the peripheral surface 1a of the pipe 1, and the first holding portion 113-1 and the second holding portion 113-2 From the viewpoint of ensuring relative rollability, the first holding part 113-1 and the second holding part 113-2 are attached so as not to cover the hinge 114.

  With such a pipe support structure 100, the pipe 1 is supported by being suspended from the ceiling. Vibration imparted to the piping due to an earthquake or the like is absorbed by the anti-vibration rubbers 120-1 and 120-2.

  However, according to the pipe support structure 100 described above, the first holding unit 113-1 and the second holding unit 113-1 in the portion corresponding to the position of the hinge 114 that connects the first holding unit 113-1 and the second holding unit 113-2. When the inner peripheral surface 113a of the holding portion 113-2 is exposed to the outside without being covered with the pair of anti-vibration rubbers 120-1 and 120-2, for example, when condensation occurs in the pipe 1 There is a possibility that water droplets adhere to the inner peripheral surface 113a of the holding portion 113 corresponding to the position of the hinge 114.

  If water droplets adhere to the inner peripheral surface 113a of the holding portion 113 corresponding to the position of the metal hinge 114, this portion may rust and corrode. As corrosion progresses, there is a concern that the hinge 114 is broken and the pipe 1 falls.

  This invention is made | formed in view of the said situation, and makes it a subject to provide the piping support structure which can suppress that rust generate | occur | produces in the suspension member of piping.

  A first pipe support structure for solving the above-described problem is a first holding part and a second holding part that are halved and have an inner peripheral surface that follows the peripheral surface of the pipe, and are connected to each other via a hinge. A suspension member having two holding portions, and a vibration-proof rubber attached to the first holding portion and the second holding portion of the suspension member, and the first holding portion and the second holding member via the vibration-proof rubber. In the pipe support structure in which the pipe is held by the holding part and is supported by being suspended from the ceiling, the anti-vibration rubber covers the inner peripheral surface of the first holding part and the peripheral surface of the pipe A first rubber body mounted on the second holding body, a second rubber body covering the inner peripheral surface of the second holding portion and mounted on the peripheral surface of the pipe, and the second rubber body and the first rubber body.

  At this time, even if dew condensation occurs in the pipe, the first holding part and the second holding part are covered with the anti-vibration rubber because the first holding part and the second holding part that constitute the suspension member are covered with the anti-vibration rubber. It is suppressed that a water droplet adheres to a part.

  Therefore, the durability of the suspension member having the first holding part and the second holding part is improved, and the pipe can be stably suspended and supported over a long period of time.

  Moreover, since the first rubber body and the second rubber body are connected by the connecting portion in a state where the hinge is exposed to the outside between the first rubber body and the second rubber body, the first holding portion and A degree of freedom of rotation relative to the second holding portion is ensured.

  The second piping support structure is the first piping support structure, wherein the first rubber body, the connecting portion, and the second rubber body are continuously formed integrally, and the first rubber body, the connecting portion, and the The thickness of the second rubber body is formed to be constant over the first rubber body, the connecting portion, and the second rubber body.

  According to this configuration, the anti-vibration rubber has a constant thickness from the first rubber body to the second rubber body via the connecting portion, and therefore the relative relationship between the first holding portion and the second holding portion. Resistance to strain and fatigue imparted to the connecting portion by a simple turning is ensured.

  The third pipe support structure is the first or second pipe support structure, wherein the first rubber body includes a pair of first engagement portions that engage with both end edges of the first holding portion, The two rubber bodies include a pair of second engaging portions that engage with both end edges of the second holding portion, and the first engaging portion and the second engaging portion are the first holding portion and the first holding portion, respectively. (2) The anti-vibration rubber is attached to the suspension member by engaging with a holding portion.

  According to this configuration, the first rubber body includes the first engaging portion that engages with both end edges of the first holding portion, and the second rubber body engages with both end edges of the second holding portion. Since the engaging portion is provided, the first anti-vibration rubber is engaged with the both end edges of the first holding portion, and the second engaging portion is engaged with the both end edges of the second holding portion. Can be easily attached to the first holding part and the second holding part. Therefore, the work efficiency in the manufacturing process of the pipe support structure is improved.

  According to this invention, durability of the suspension member having the first holding part and the second holding part is improved, and the pipe can be stably suspended and supported over a long period of time.
