Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support member for piping, and more particularly, to a support member for preventing a portion of a synthetic resin piping disposed around the water of a building from hanging down.
[0002]
[Prior art]
Conventionally, as a device for supporting a synthetic resin drain pipe disposed in a general house at a predetermined position, one disclosed in JP-A-8-170759 or various other devices has been provided. . An example is shown in FIG. The support device 20 inserts the projecting pieces 23b, 23b of the holding member 23 having the annular portion 23a into the screw rod 22 fixed to the base 21, tightens the nuts 24, 24, and holds the drain pipe 25 by the annular portion 23a. It is like that.
[0003]
[Problems to be solved by the invention]
By the way, in recent years, a long flexible pipe is used as a drain pipe in consideration of the convenience of piping work. The flexible tube is easy to bend downward, and is unsanitary when drainage accumulates. Therefore, the support device 20 is frequently used with its mounting interval narrowed.
[0004]
However, in the said support apparatus 20, it is necessary to attach the base 21 to the floor surface and wall surface of a building one by one. Therefore, using a large number of support devices 20 with a narrow mounting interval has a problem that the work is complicated and the cost is increased.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a support member that can hold a flexible pipe while preventing it from drooping with a simple configuration of one component.
[0006]
[Summary and Effect of the Invention]
In order to achieve the above object, a support member for piping according to the present invention includes a substantially arc-shaped holding ring portion that can be crimped to an outer peripheral surface of a pipe, and a plate-like portion that connects at least two holding ring portions. The plate-like portion has a wave shape in the plate thickness direction and is flexible, and is rigid in the plate width direction , and is axially coupled to the bottom of the holding ring portion at the plate thickness surface portion. It is characterized by.
[0007]
The support member according to the present invention presses at least two holding ring portions to the outer peripheral surface of the pipe, so that the plate-like portion plays a role of a splint and prevents the pipe from drooping downward. Plate-like portion may have a flexible form a waveform in the thickness direction, and corresponds to the curvature of the pipe by have a stiffness in the plate width direction.
[0008]
According to the present invention, the holding ring portion and the plate-like portion connecting the holding ring portion are extremely simple, and it is possible to prevent the sagging of the flexible tube by itself. Note that the support member according to the present invention does not require all of the support device 20 as shown in FIG. By using the support device 20 in the necessary range in places where it is necessary to support the building, and using this support member in place of the support device 20 in some places, the workability during construction is improved and low Cost reduction is realized.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a support member according to the present invention will be described with reference to the accompanying drawings.
[0010]
In FIG. 1, a support member 10 is integrally formed of a hard synthetic resin (for example, ABS resin), and has arc-shaped holding ring portions 11 and 11 at both ends. A long plate-like portion 12 is connected in the axial direction.
[0011]
The retaining ring portion 11 has elasticity, has an arc shape with a missing apex portion, and can be crimped to the outer peripheral surface of the flexible drain pipe 1. The plate-like part 12 is joined to the bottom part of the retaining ring part 11 at both ends of the plate-like part 12 at the plate thickness surface part. The plate-like portion 12 has a waveform in the plate thickness direction, has flexibility in the plate thickness direction a, and has rigidity in the plate width direction b. That is, the plate-like portion 12 does not warp as indicated by the alternate long and short dash line c.
[0012]
The drain pipe 1 is basically piped to a building structure using the support device 20 shown in FIG. 5 or another support device at a relatively wide interval. In this case, the retaining ring portions 11, 11 are pressure-bonded to the outer peripheral surface of the drainage pipe 1 at the intermediate portion of the support devices 20, 20, and the plate-like portion 12 is attached so as to be positioned directly below the drainage pipe 1. In the attached state, the plate-like portion 12 has rigidity in the direction of the arrow b, so that the drain pipe 1 is prevented from hanging down.
[0013]
Even if the drain pipe 1 is curved on a horizontal plane, the plate-like portion 12 is flexible in the thickness direction (arrow a direction), so that the drain pipe 1 is curved. Can be met.
[0014]
Next, the flexible drainage pipe 1 will be described with reference to FIGS. 2 and 3. Of course, the drain pipe 1 is an example of a pipe using the support member 10.
[0015]
In FIG. 2, the drain pipe 1 is integrally formed by winding a tape made of a soft synthetic resin (for example, a soft vinyl chloride resin) in a spiral shape and fusing adjacent side edges of the wound tape. The formed inner layer 2 and a hard synthetic resin (for example, hard vinyl chloride) formed in the bent tip portions 4a and 4b whose cross-sectional shape is substantially S-shaped along the outer peripheral surface of the inner layer 2 and whose opposite ends are opposite to each other. The outer layer 3 is formed by winding a belt 4 made of a resin) in a spiral shape and polymerizing and joining the adjacent bands 4. The inner peripheral surface of the inner layer 2 is formed almost smoothly, and the outer surface of the outer layer 3 is formed with uneven portions along the axial direction.
[0016]
The belts 4 and 4 are in contact with each other without being fused to the convex inner peripheral surface 4c of the strip 4 with the upward tip portion 4a adjacent thereto, and with the concave peripheral surface 4d of the strip 4 with the downward tip portion 4b adjacent thereto. And can move in the axial direction.
[0017]
The drain pipe 1 can be bent at an arbitrary position, and FIG. 3 shows a bent state. On the outer peripheral side C of the bent portion, the band 4 is extended in the axial direction until the upward tip portion 4a engages with the adjacent downward tip portion 4b. On the other hand, on the inner peripheral side B, the belt body 4 contracts.
[0018]
In addition, the support member which concerns on this invention is not limited to the said embodiment, It can change variously within the range of the summary.
For example, the plate-like portion 12 may not be a waveform but may be a flat shape as shown in FIG. Further, the retaining ring portion 11 may be provided at an intermediate portion other than both ends of the plate-like portion 12.
