Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a support device for supporting a pipe installed for supplying and discharging a heat medium such as cold and hot water and steam to, for example, an air conditioner, and more particularly to an improvement of a support device for a pipe covered with a heat insulating material. It is a thing.

[0002]

[Prior art]

 There are, for example, the following two configurations for supporting this type of pipe on the support frame. (First Conventional Example) In the first conventional example, as shown in FIGS. 4 (A) and 4 (B), the pipe 1 is fixed to the support frame 7 by the U bolt 20.

Second Conventional Example On the other hand, in the second conventional example, as shown in FIGS. 5 (A) and 5 (B), a spacer 22 having a heat insulating property is fitted onto the pipe 1 and the spacer 22 Is fixed to the support frame 7 using a belt 23.

[0004]

[Problems to be solved by the device]

 In the above-mentioned first conventional example, since the above-mentioned U bolt 20 is directly placed on the above-mentioned frame 7, the above-mentioned U-bolt 20 and the above-mentioned frame 7 interfere with each other, and as shown in FIG. As shown, the outer peripheral surface 1a of the pipe 1 cannot be covered with the heat insulating material 6 at the location where the U bolt 20 is arranged. As a result, the above-mentioned pipe 1 cannot be sufficiently insulated.

Further, in the above-mentioned first conventional example, since the pipe 1 is pressed and fixed to the support frame 7 by the tightening force of the U-bolt 20, the pipe 1 rotates in the circumferential direction. It's easy to do.

On the other hand, in the second prior art example, the spacer 22 supports the pipe 1 on the support frame 7, and the spacer 22 covers the outer peripheral surface 1 a of the pipe 1. Therefore, it is possible to have a sufficient heat insulating effect. However, in the above-mentioned second conventional example, the spacer 2 is formed on the outer peripheral surface 1a of the pipe 1.
Since 2 is only fitted outside, the pipe 1 is easy to rotate in the circumferential direction as in the above-mentioned first conventional example.

Therefore, in the above-mentioned first conventional example and second conventional example, the above-mentioned pipe 1 is rotated and detached from the joints during pipe construction, and the pipe 1 and the joints are separated from each other. The connection may be loosened and the heat medium in the tube 1 may leak out of the tube. It is an object of the present invention to provide a pipe support device capable of covering the outer peripheral surface of a pipe with a heat insulating material without a gap and preventing rotation of the pipe in the circumferential direction.

[0008]

[Means for Solving the Problems]

In order to achieve the above object, the present invention is configured as follows, for example, as shown in FIGS. A support 2 is arranged between the pipe 1 covered with the heat insulating material 6 and the support frame 7, and the heat insulating material is provided between the outer peripheral surface 1 a of the pipe 1 and the support frame 7 by the support 2. The mounting gap C of 6 is formed, the support tool 2 is fixed to the support frame 7, and the outer peripheral surface 1a of the pipe 1 is fixed to the support tool 2.

[0009]

[Action]

 This invention operates as follows, for example, as shown in FIGS. That is, the piping support device is assembled in the following procedure. As shown in FIG. 1 (A), a support member 2 is arranged between the pipe 1 and the support frame 7 so that a space for mounting the heat insulating material 6 is provided between the pipe 1 and the frame 7. An interval C is formed. Thereby, the heat insulating material 6 can be attached to the outer peripheral surface 1a of the pipe 1 even between the pipe 1 and the frame 7. Further, since the outer peripheral surface 1a of the tube 1 is fixed to the support tool 2, rotation of the tube 1 in the circumferential direction is prevented.

[0010]

[Effect of device]

 The present invention has the following effects because it is configured and operates as described above. Since a gap for mounting the heat insulating material is formed between the pipe and the support frame, the heat insulating material can be attached to the outer peripheral surface of the above pipe even between the above pipe and the above frame, and the outer circumference of the above pipe can be attached. The surface can be covered with a heat insulating material without gaps. Therefore, the heat insulation of the above pipe can be maintained high.

Further, since the outer peripheral surface of the pipe is fixed to the support, the support can surely prevent the pipe from rotating in the circumferential direction. Therefore, it is possible to reliably prevent the above-mentioned pipe from rotating and coming off the joints during pipe construction, and the heat medium inside the pipe from leaking out of the pipe due to loose connection between the pipe and the joints.

When the outer peripheral surface of the pipe is fitted into the recess formed in the support to weld the outer peripheral surface of the pipe and the recess to each other, the support is The above-mentioned pipe can be securely fixed to the above, and the rotation of the above-mentioned pipe can be prevented more reliably.

Further, when a supporting member is formed on a thin plate extending in a direction orthogonal to the axial direction of the pipe, and the thin plate is provided with the recessed portion and is welded to the pipe, the pipe is The welding range of the concave portion with respect to the outer peripheral direction of the tube can be increased, so that the tube is firmly fixed to the support tool.

Further, when the support tool is covered with another heat insulating material, the heat of the heat medium in the tube can be prevented from escaping through the support tool, and the heat insulating property of the tube can be further improved. Can be maintained.

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a longitudinal sectional view showing an embodiment of a pipe supporting device according to the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1 above, and FIGS. It is a figure for demonstrating the assembly procedure of the piping support apparatus.

The above pipe supporting device is provided to support the metal pipe 1 on the support frame 7 by the support 2. The metal pipe 1 is provided for supplying and discharging a heat medium such as cold and hot water or steam to, for example, an air conditioner. That is, the support 2 is made of a thin plate and is arranged between the metal tube 1 and the support frame 7. The support 2 is formed in an L-shaped cross section by the upright portion 3 and the support portion 4 extending from the lower end of the upright portion 3 in the axial direction of the metal tube 1.

The upright portion 3 extends in a direction orthogonal to the axial direction of the metal tube 1. A semicircular concave portion 5 is formed at the upper end of the upright portion 3, and the outer peripheral surface 1a of the metal tube 1 is fitted into the concave portion 5. Then, in this fitted state, the metal tube 1 and the above-mentioned concave portion 5 are welded and fixed. The metal tube 1 and the support tool 2 are welded together by welding such as gas welding or arc welding.

The support portion 4 is fixed to the frame 7 by two pairs of bolts 8 and nuts 9 while being mounted on the upper surface of the support frame 7. Further, the outer peripheral surface 1a of the metal tube 1 is covered with a heat insulating material 6 in a state where the metal tube 1 and the support tool 2 are welded to each other. The heat insulating material 6 is made of glass wool (glass fiber), foamed plastic, urethane foam, or the like.

Further, the metal tube 1 is supported by the support 2 at a predetermined distance from the support frame 7, whereby the outer peripheral surface 1 a of the metal tube 1 and the support frame 7 are supported. A space C for mounting the heat insulating material 6 is formed between them. As a result, the heat insulating material 6 can be easily attached to the outer peripheral surface 1a of the metal tube 1 even between the metal tube 1 and the frame 7, and the outer periphery of the metal tube 1 can be easily attached. The surface 1a can be covered with the heat insulating material 6 without any gap.

Next, an example of an assembling procedure of the above piping support device will be described with reference to FIGS. 3 (A) and 3 (B). First, the recessed portion 5 of the upright portion 3 of the support tool 2 is fitted to the outer peripheral surface 1a of the metal tube 1.

This can be reliably prevented. Therefore, it is possible to surely prevent the above-mentioned metal pipe 1 from rotating and coming off from the joints during pipe construction, and the connection between the pipes and the joints from loosening and the heat medium inside the pipes leaking out of the pipes.

Further, since the upright portion 3 of the support member 2 is formed of a thin plate, the welding range of the recessed portion 5 of the upright portion 3 with respect to the outer peripheral direction of the metal tube 1 is increased, and the metal tube 1 is It is firmly fixed by the support tool 2 of.

When the heat insulating material 6 is formed of a flexible material, the mounting gap C between the metal tube 1 and the supporting frame 7 is slightly smaller than the thickness D of the heat insulating material 6. Since the heat insulating material 6 can be attached to the outer peripheral surface 1a of the metal tube 1 even if it is made small, it is not always necessary to make the mounting gap C above the thickness D of the heat insulating material 6.

The above embodiment can be modified as follows. That is, the support 2 may be covered with the heat insulating material 6. In this case, the heat of the heat medium can be prevented from escaping through the support 2, and the heat insulation of the metal tube 1 can be maintained higher.

Further, in the above description, the outer peripheral surface 1a of the metal tube 1 and the recessed portion 5 of the support tool 2 are fixed by welding, but for example, the outer peripheral surface 1a of the metal tube 1 and the support tool 2 are fixed. The concave portion 5 may be fixed with an adhesive, or may be fixed with brazing or soldering.

Further, although the support portion 4 of the support tool 2 is fixed to the support frame 7 by the bolt 8 and the nut 9, the support portion 4 of the support tool 2 may be welded to the support frame 7, or You may fix with an adhesive agent.

Further, the support tool 2 is not limited to being formed of a thin plate, and for example, the upright portion 3 of the support tool 2 may be formed in a rod shape or a block shape, or two pillars as described above. The upright portion 3 may be formed.
