Description

  The present invention relates to a gantry optimal for protecting a resin header, and a piping system including the same.

In buildings such as houses, pipes (for example, water supply pipes and water distribution pipes) are often laid under the floor. For example, in an apartment house, when piping is laid on the second floor, piping is laid under the floor on the second floor (see, for example, Patent Document 1).
In recent years, resin pipes are widely used for water supply and hot water supply pipes even in detached houses such as apartment houses, and along with this, resin pipe joints are also widely used. It has become. Usually, the main pipe is collected in the header portion, and the branch pipe is piped to a necessary part.

  By the way, since the number of devices using water is various, a connection type header that connects a plurality of joints according to the number of devices is commercially available. In this connection type header, each joint is freely rotatable, and the branch pipe can be arranged in a desired direction.

JP 2003-249171 A

  By the way, although this kind of header is arranged on the slab of a building, an operator may step on by mistake at a construction site. Since the metal header is highly rigid, it could not be damaged even if it is accidentally stepped on.However, in the connection type header that connects the header made of synthetic resin for weight reduction, it is made of metal. Compared to its low rigidity, if a bending stress is applied by stepping on, placing a heavy object, or accidentally dropping a transported object by an operator, the stress concentrates on the connection part and breaks the connection type header. It is possible to do.

  This invention makes it a subject to provide the mount which prevented the header from being damaged by the press and impact from the upper part, and a piping system provided with the same in view of the said fact.

  The invention according to claim 1 is a connection type header formed by connecting a plurality of header bases having a main pipe part and a branch pipe connection part provided in the main pipe part for connecting branch pipes so as to be relatively rotatable. A strength member positioned on the upper side; suspension means attached to the strength member to suspend and hold the header; and leg portions extending from the strength member.

In the first aspect of the present invention, the gantry can be placed or fixed on the floor slab in a state where the header is suspended from the suspension means. Therefore, even if the worker steps on the header accidentally or the worker accidentally drops the transported material from above the header, the strength member protects the header, so there is no possibility of damaging the header.
Moreover, since it is a form suspended by the suspension means, it is not necessary to firmly fix the header to the strength member. For this reason, there is no possibility of damaging the header due to an excessive load by an operator or a tool.

The invention according to claim 2 is provided with a U-shaped side band fixed to the lower surface side of the strength member as the suspending means.
The size of the side band is set so that the lower end position of the U-shaped portion of the side band does not protrude below the lower end position of the leg portion.

According to a third aspect of the present invention, the strength member is transparent.
This makes it possible to visually recognize the header, which is particularly effective when an abnormality occurs in the header or during inspection.

The invention according to claim 4 includes a plurality of joints having a main pipe part and a branch pipe connection part provided in the main pipe part for connecting branch pipes, and the ends of the main pipe part are relatively rotatable. A support portion that supports a connection type header that is connected to the support portion from below, a fixing means that fixes the header to the support portion, and an arm portion that extends from the support portion and is fixed to the ceiling. Yes.
In the invention according to claim 4, the arm is attached to the ceiling, so that the gantry is suspended from above. Therefore, the worker does not step on the header by mistake, and the worker does not accidentally drop the transported item on the header.
Further, in a state where the gantry is suspended from above, the header is supported from below by the support portion. Therefore, even if the worker hangs or grabs the header during work and supports the weight with the header, the support portion serves as a reinforcement member for the header. Even if an operator inserts a pipe into the header branch port and releases the pipe winding tube as it is and a load is applied to the header, the support portion serves as a header reinforcement member.

According to a fifth aspect of the present invention, a U-shaped side band fixed to the upper surface side of the strength member is provided as the fixing means.
The dimensions of the side band are such that the upper end position of the U-shaped part of the side band does not protrude above the upper end position of the leg part.

In the invention according to claim 6, the support portion is transparent.
This makes it possible to visually recognize the header, which is particularly effective when an abnormality occurs in the header.

A seventh aspect of the invention includes the gantry according to any one of the first to third aspects, and the header suspended from the gantry by the suspending means.
In the invention according to claim 7, even if the worker steps on the header accidentally or the worker accidentally drops the transport object from above the header, the header is damaged because the strength member protects the header. There is no fear.

The invention according to an eighth aspect includes the gantry according to any one of the fourth to sixth aspects, and the header supported on the gantry from below by the support portion.
In the invention according to claim 8, the piping system can be suspended from above by attaching the arm portion to the ceiling or the like. Therefore, the worker does not step on the header by mistake, and the worker does not accidentally drop the transported item on the header.
In addition, when the piping system is suspended from above, the header is supported from below by the support portion. Therefore, even if the worker hangs or grabs the header during work and supports the weight with the header, the support portion serves as a reinforcement member for the header. Even if the worker inserts the pipe into the header branch port and releases the pipe winding tube (for example, about 10 kg) as it is and a load is applied to the header, the support portion serves as a header reinforcing member.

  ADVANTAGE OF THE INVENTION According to this invention, it can be set as the mount which prevented the header from being damaged by the press and impact from the upper part, and a piping system provided with the same.

  Hereinafter, embodiments will be described and embodiments of the present invention will be described. In the second and subsequent embodiments, the same components as those already described are denoted by the same reference numerals, and description thereof is omitted.

[First Embodiment]
First, the first embodiment will be described.
1 and 2 show a piping system 10 according to the present embodiment. The piping system 10 includes a connection type header 12 and a mount 13 according to this embodiment that suspends the header 12 and protects the upper side of the header 12.

  As shown in FIGS. 4 to 6, the header 12 is formed by connecting a plurality of header bases 14. The header base 14 is integrally provided with a branch pipe connecting portion 18 in the main pipe portion 16. A straight flow path 20 is provided inside the main pipe portion 16, and a rising flow path 22 is provided inside the branch pipe connection portion 18.

  The branch pipe connecting portion 18 is provided with a synthetic resin inner cylinder 26 that is inserted into the resin pipe 24 connected to the rising flow path 22, for example, colored in black, on the outer surface of the inner cylinder 26. An O-ring 30 is fitted in the formed circumferential groove 28.

A transparent synthetic resin outer cylinder 32 is disposed on the outer peripheral side of the inner cylinder 26 through a gap into which the resin pipe 24 is inserted. A pipe holding ring 34 having a V-shaped cross section is disposed on the distal end side of the outer cylinder 32, and a cylindrical cap 36 for preventing the pipe holding ring 34 from being detached is attached to the outer cylinder 32. .
In addition, a release ring 38 for releasing the biting of the claw portion of the pipe holding ring 34 is mounted inside the cap 36.

  When the resin pipe 24 is inserted between the inner cylinder 26 and the outer cylinder 32, the inner peripheral side end of the pipe holding ring 34 is caught on the outer peripheral surface of the resin pipe 24 to prevent the resin pipe 24 from coming off. Thus, the O-ring 30 is in close contact with the inner peripheral surface of the resin pipe 24 for sealing (so-called inner surface sealing). The resin pipe 24 is rotatable while being inserted between the inner cylinder 26 and the outer cylinder 32.

  When the release ring 38 is pushed in and pressed against the pipe holding ring 34, the taper portion of the release ring 38 slides on the inclined surface on the inner peripheral side of the pipe holding ring 34, and the inner diameter of the release ring 34 is increased to increase the resin pipe. The hook with 24 is released, and the resin pipe 24 can be pulled out.

  One end portion of the main pipe portion 16 has the same structure as that of the branch pipe connecting portion 18, and the other end portion is a cylindrical body portion 40 having the same inner and outer diameter as the resin pipe 24. And the outer cylinder 32 can be inserted.

  Therefore, by inserting the cylindrical body portion 40 of the main pipe portion 16 of the header base body 14 between the inner and outer cylinders of the main pipe portion 16 of another adjacent header base body 14, the two-dot chain line in FIG. 1 and FIG. As shown, a plurality of header bases 14 can be connected in a straight line to form a connection type header 12 in which each header base 14 can be rotated.

As shown in FIGS. 1 and 2, the gantry 13 is provided with a rigid strength member 51 and a side band 56 that suspends the header 12 on the lower surface side of the strength member 51. In the present embodiment, the strength member 51 is transparent and is made of, for example, a reinforced plastic material.
As shown in FIG. 2, the strength member 51 is turned upside down when the header 12 is fixed. At this time, an elongated placement portion 50 on which the header 12 is placed is provided at the center position in the width direction of the strength member 51. Further, the strength member 51 is formed with elongated side portions 52 that are respectively continuous on both sides of the placement portion 50 in the width direction. In the side portion 52, a pore portion 54 for fixing a side band 56 described later is formed at a predetermined position. 1 and 2 show the pores 54 formed in the side portion 52 that can be seen on the near side, the fine side portions on the opposite side (the far side) from the near side are also similarly fine. A hole is formed.

  Further, the side band 56 is U-shaped when viewed from the mounting portion longitudinal direction U. When the piping system 10 is installed, the side band 56 extends toward the outer side in the width direction as shown in FIG. Sideband legs 62 are formed. The sideband 56 can be fixed at an arbitrary position in accordance with the position of the header 12 with screws, screws, bolts, or the like that are inserted through the pores 54 of the sideband leg portion 62, that is, the length of the header 12. A circular hole 64 is formed in the side band leg 62 so that the header 12 can be fixed with a degree of freedom.

  Further, the gantry 13 has leg portions 63 attached so as to extend downward from the support material corners on both sides in the longitudinal direction of each side portion 52, that is, from the four corners of the strength member 51. The leg portion 63 extends downward from the lower end 56L of the side band 56. The leg part 63 may be fixed to the strength member 51 or may be detachably attached.

In the present embodiment, the strength member 51 to which the leg portion 63 is attached is turned upside down, that is, the back surface side of the strength member 51 is turned upward, and the header 12 connected to the plurality of header bases 14 is placed on the placement portion 50. Placed on. Then, the side band 56 is attached to the strength member 51.
Then, the header 12 is suspended from the side band 56 by turning the gantry 13 upside down. The gantry 13 is placed or fixed at a predetermined position such as on the floor slab or on the ceiling (the back side of the ceiling).

  Thus, in this embodiment, the header 12 is suspended by the side band 56 below the strength member 51. As a result, even if the worker steps on the header 12 accidentally from above or the worker accidentally drops the transported material from above the header 12, the strength member 51 serves as a reinforcing cover, and the header 12 Since it protects, there is no possibility that the header 12 will be damaged.

Further, the header 12 is suspended by the side band 56, and it is not necessary to firmly fix the header 12 to the strength member 51. It is also possible to adopt a configuration in which the header 12 can be fixed to the mounting portion 50 by attaching the side band 56 to the strength member 51.
Furthermore, since the strength member 51 is transparent, the header 12 can be visually recognized. This is particularly effective when an abnormality occurs in the header 12.

  Further, by rotating any one of the header bases 14, it is possible to connect any branch pipe connecting portion 18 in a different direction. For example, as shown by a two-dot chain line in FIGS. 1 and 2B, the header base 14 can be rotated by 90 ° and connected by piping.

  In the above description, the example in which the sideband 56 is U-shaped has been described. However, the present embodiment is not limited to this example. For example, as illustrated in FIG. There may be. Moreover, although the example in which the side band 56 is attached by screws, screws, bolts, etc. has been described, a clamp, a hinge, a hole, etc. are provided in the strength member 51 as necessary so that the side band can be attached with one touch.
