The structure of Patent Document 1 is a structure having an upper tubular body that is movably inserted into a lower tubular body through a connecting cylinder connected to a water supply pipe. A pipe body is inserted so as to be movable up and down, and a sprinkler joint is provided at the upper end of the upper pipe body.
Therefore, if the sprinkler, which is the ground part, or its strut pipe receives strong winds or other external forces, if the strut pipe only bends or bends, it is sufficient to replace it from the joint. When the body, the water supply pipe, the connecting pipe, the lower pipe, etc. are damaged, the damage is enormous, and there is a big problem that the replacement requires cost and time.

The technical problem of the present invention focuses on such problems, and in order to minimize damage damage, the lower end side of the pedestal-supported sprinkler strut pipe is connected to the underground via an exchangeable flange joint. The object is to realize a structure for mounting and fixing to the pedestal side.

The technical problem of the present invention is solved by the following means. Claim 1 is a structure for connecting a column pipe side of a sprinkler to a pipe in a sprinkler pedestal supplied with water from a water supply pipe,
With the lower pipe of the exchange joint with flange inserted in the receiving pipe standing in the pedestal, the flange is detachably fixed to the pedestal side, and the sprinkler strut pipe side is attached to and detached from the upper pipe The sprinkler mounting structure is characterized in that the structure is connected in a formula.

In this way, with the lower pipe of the exchange joint with flange inserted in the receiving pipe standing upright in the base, the flange is detachably fixed to the base, and the sprinkler column is attached to the upper pipe. Since the pipe side is structured to be detachably connected, even if the exchange joint upper pipe that is most susceptible to the strongest external force is damaged, the exchange joint can be easily detached and replaced.
Therefore, even if the sprinkler which is the ground part, its supporting pipe, the exchange joint, etc. are damaged by typhoon or other external force, it can be easily and quickly replaced and immediately responded.

Claim 2 is an apparatus for connecting the sprinkler strut pipe side to the pipe in the sprinkler base connected to the water supply pipe,
A receiving pipe communicating with the piping in the pedestal is erected in the pedestal,
The flange of the exchange joint with the flange can be detachably attached to the pedestal side, the lower pipe on the lower side of the flange is inserted into the receiving pipe, and the sprinkler strut pipe side is detachably connected to the upper pipe A structure to
The sprinkler mounting structure characterized by the above.

In this way, the receiving pipe communicating with the piping in the pedestal is erected in the pedestal, and the flange of the exchange joint with the flange can be detachably attached to the pedestal side, and the lower side of the flange can be fixed. Since the side pipe is inserted into the receiving pipe and the sprinkler strut pipe side is detachably connected to the upper pipe, the sprinkler side can be easily and quickly connected to the piping in the base in a detachable manner. it can.
Also, the flange of the exchange joint with flange can be detachably attached and fixed to the pedestal side by means such as bolts and nuts, so the sprinkler strut tube side is firmly attached and fixed to the pedestal side so that it will not easily fall down due to wind pressure etc. it can.

According to a third aspect of the present invention, a sealing ring such as an O-ring is attached to the inner periphery of the receiving pipe, and the inner diameter thereof is smaller than the outer diameter of the lower pipe of the exchange joint. The sprinkler mounting structure according to claim 1 or claim 2.
In this way, a sealing ring such as an O-ring is attached to the inner periphery of the receiving pipe that is erected in the pedestal, and its inner diameter is smaller than the outer diameter of the lower pipe of the exchange joint. Water leakage can be reliably prevented when water is supplied from the piping to the sprinkler side. In addition, insertion and extraction of the lower pipe of the exchange joint into the receiving pipe can be easily performed with one touch against the elasticity of the sealing ring.

As in claim 1, the flange of the exchange joint is detachably fixed to the pedestal side, so that the exchange joint can be easily removed and replaced even if the upper pipe of the exchange joint that is susceptible to the strongest external force is damaged. Therefore, even if the sprinkler that is the ground part, its support pipe, replacement joints, etc. are damaged by typhoons or other external forces, they can be replaced easily and quickly.

Since the lower pipe of the exchange joint is inserted into the receiving pipe and the sprinkler column pipe side is detachably connected to the upper pipe as in claim 2, the sprinkler side can be easily and quickly installed in the base. It can be connected to the pipe in a detachable manner to supply water.
In addition, since the flange of the exchange joint can be detachably attached and fixed to the pedestal side with bolts and nuts, the sprinkler strut tube side can be firmly attached and fixed to the pedestal side so that it does not easily fall down due to wind pressure or the like.

Since the inner diameter of the O-ring attached to the inner periphery of the receiving pipe erected in the pedestal is smaller than the outer diameter of the lower pipe of the exchange joint, the water supply from the pipe to the sprinkler side is required. Water leakage can be reliably prevented. In addition, insertion and extraction of the lower pipe of the exchange joint into the receiving pipe can be easily performed with one touch against the elasticity of the sealing ring.

Next, an embodiment of how the sprinkler mounting structure according to the present invention is actualized will be described. FIG. 1 is a side view (1) of a replacement joint in a sprinkler mounting structure according to the present invention and a longitudinal sectional view (2) of its mounting state. As shown in (2), a concrete sprinkler base 1 is almost Is embedded in the ground e, and only the upper end is partially exposed. In the case of the illustrated example, the water supply pipe in the pedestal 1 has a structure in which a rising pipe 3 and a horizontal pipe 4 are connected via an elbow joint 2, and the water supply pipe is connected to the horizontal pipe 4 to supply water from a water supply or the like. It has become.

As is clear from the enlarged view of FIG. 2, the rising pipe 3 is inserted from the bottom until it hits the stopper S at the intermediate position in the vertical socket pipe 5, and the receiving pipe 6 with the sealing ring O is inserted into the stopper S from above. It is inserted until it hits. In this state, the socket tube 5 and the receiving tube 6 are also disposed in the concrete of the base 1.

The periphery 8 is raised like a bank so that the concave chamber 7 is formed at the upper part of the pedestal 1, and the drain hole 16 is penetrated from the bottom of the concave chamber 7.
A female screw tube 9 and a nut are embedded in the bottom surface of the concave chamber 7 so that the mounting bolt B can be screwed therein.

FIG. 1 (1) shows an exchange joint 10, which has a disk-like flange f horizontally at an intermediate portion of a vertical tubular body, and an upper pipe P1 above and a lower lower pipe P2 below the flange f. And the flange f are integrated. The material is preferably made of metal such as stainless steel. A plurality of insertion holes h for the mounting bolts B are formed in the flange f, and a male screw 11 is formed on the upper portion of the upper pipe P1 so that a sprinkler joint can be screwed. The lower space P2 is inserted into the receiving tube 6 as shown in FIG.

FIG. 2 is an enlarged longitudinal sectional view of the exchange joint 10 attached to the pedestal 1 side. The lower pipe P2 of the exchange joint 10 is inserted into the receiving pipe 6 on the pedestal 1 side. Since the bolt B is inserted into the bolt hole h of the flange f and screwed into the female screw tube 9 on the pedestal side, the exchange joint 10 is attached and fixed to the pedestal 1 side in the concave chamber 7. Since a sealing ring such as an O-ring O is fitted on the inner periphery of the receiving pipe 6, there is no fear of water leakage with the lower pipe P2 inserted. The sealing ring O is a rubber-like elastic material.

FIG. 3 shows a state before the replacement joint 10 is mounted. Since the inner diameter of the O-ring O is smaller than the outer diameter of the lower pipe P2, the elastic O-ring O is crimped in the inserted state of the lower pipe P2. As a result, watertightness is ensured and water does not leak.

FIG. 4 shows a state in which the sprinkler is attached, and a sprinkler support pipe 13 is attached and connected to a male thread 11 at the upper end of the upper pipe P1 of the exchange joint 10 in FIGS.
A sprinkler 15 is attached to the upper end of a small-diameter pipe 14 that moves up and down in the sprinkler support pipe 13.

Therefore, when liquid such as tap water, ground water, liquid fertilizer, or chemical liquid flows from a water supply pipe (not shown), the horizontal pipe 4 → elbow joint 2 → rise pipe 3 → socket pipe 5 → receiving pipe 6 → exchange joint 10 in FIG. The lower pipe P2, the upper pipe P1, the detachable joint 12, the sprinkler support pipe 13, the telescopic small-diameter pipe 14, and the sprinkler 15 flow in this order and are sprinkled.

Now, when the sprinkler 15 or its column tube 13 and the expansion tube 14 are bent or broken due to strong wind or impact, the detachable joint 12 is separated from the exchange joint 10 on the base 1 side, and the upper side from the sprinkler column tube 13 is Just remove and replace.
However, since it is the upper pipe P1 of the exchange joint 10 at the lower end position that is most easily damaged by an external force, the upper pipe P1 is often damaged. In this case, the bolt B can be removed, the replacement joint 10 is removed, the replacement joint 10 is replaced, and then the sprinkler post pipe 13 is attached and connected via the attachment / detachment joint 12 to quickly and easily cope with it. Therefore, the time to stop watering can be shortened.

Instead of the detachable bolt B, an anchor bolt may be embedded and fixed in the concrete pedestal 1 in the concave chamber 7 to expose the male screw portion. In this case, a nut is screwed onto the male screw portion from above with the male screw portion exposed upward being inserted through the bolt hole h of the flange f.

In the above configuration, the elbow joint 2, the rising pipe 3, the horizontal pipe 4, the socket pipe 5, and the receiving pipe 6 are suitably made of synthetic resin such as vinyl chloride.
The piping in the pedestal 1 in FIG. 1 uses a T-shaped joint instead of the elbow joint 2, so that if the horizontal pipe 4 is connected to both, water can be supplied to adjacent sprinklers, and a large number of sprinklers can be operated simultaneously. Become.

As described above, according to the present invention, the replacement joint is fixed to the pedestal side connected to the water supply pipe in a detachable manner, and the sprinkler strut pipe side is detachably connected to the replacement joint. If the sprinkler strut pipe side is damaged, the exchange joint can be removed and replaced from the pedestal side, and the response to the damage can be made smoothly and quickly.

They are the side view of the exchange joint (1) in the sprinkler mounting structure by this invention, and the longitudinal cross-sectional view of the mounting state (2). It is an expanded longitudinal cross-sectional view of the state which attached the exchange coupling to the base side. It is an expanded sectional view which shows the base of the state which removed the exchange coupling. It is a pedestal sectional view showing the attachment state of a sprinkler.
