Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for preventing rotation of a seismic saddle tap.

[0002]

2. Description of the Related Art As a water tap for branching a water supply pipe from a water distribution pipe to each demanding household, a saddle water tap 1 as shown in FIG. 4 is used.

[0003] The saddle tap 1 is connected to a water pipe 2 (FIG. 5).
The upper saddle 1A includes a semi-circular upper saddle 1A and a semi-circular lower saddle 1B. A water tap 5 is attached to the upper saddle 1A, and the upper and lower saddles are fastened with fasteners 6 such as bolts and nuts. ing.

The saddle tap 1 is attached to the outer periphery of the water pipe 2, so that it becomes a projection on the outer circumference of the water pipe 2. Further, the saddle water tap 1 and the water pipe 2 are usually buried underground.

[0005] For this reason, when the ground changes due to an earthquake or the like, the saddle tap 1 is susceptible to the influence, and there is a problem that a water leakage accident is easily caused. In addition, since such a water leakage accident occurs all at once in the surrounding area where the earthquake occurs, a large amount of water is wasted due to the water leakage, and there has been a problem that much labor and time are required for the subsequent recovery.

Therefore, for the purpose of solving the above problem, the water tap 5 is rotatably mounted on the upper saddle around the shaft, and is rotated when an external force is applied to release the external force. A seismic-resistant saddle faucet has been proposed to prevent breakage and leakage of water and water supply pipes (Japanese Patent Application No. 9-9839).

However, when the water intake hole 2A is formed in the water distribution pipe 2, the cap 5E is removed and a drill (not shown) of a drilling tool is inserted through the inside of the water faucet 5 so that the water faucet 5 is inserted.
However, there was a problem that it was dangerous during drilling work because it was rotated with the drill.

[0008] Therefore, when drilling a water intake hole in the water distribution pipe, it is necessary to ensure that the water faucet is prevented from rotating with the drilling tool in FIG.
As shown in FIG. 6, a stopper 5A and a stopper 1C are provided on the water faucet side and the saddle side, respectively, so that the installation can be performed safely and easily. Has proposed a seismic resistant saddle faucet with the same seismic function as before.

[0009]

However, while the seismic saddle water tap having the above-described structure can prevent rotation during drilling, the stopper 5A of the water tap 5 and the saddle-side stopper 1C as shown in FIG. When a hole is drilled in a state where there is a gap indicated by θ, the water faucet rotates by the gap of θ due to rotation with the drill, and the stoppers 5A and 1C may violently collide with each other.

In order to avoid this, as shown in FIG. 7, prior to drilling, the water tap is rotated in the direction of rotation of the drill in advance so that the stoppers are brought into contact with each other, and the drill is driven. After completion, it is necessary to rotate the stopper in the reverse direction until the stoppers come into contact with each other, and rotate in the direction of the drilling removal rotation. There was a problem that handling was troublesome, such as the need to return to the neutral position.

In order to solve the above-mentioned problems, the present invention provides an earthquake-resistant saddle water faucet provided with a stopper so as not to rotate with the drill at the time of drilling. The purpose of any of them is to provide a rotation-preventing jig for a seismic saddle faucet that can prevent rotation.

[0012]

According to a first aspect of the present invention, there is provided an anti-rotation jig for an earthquake-resistant saddle spout, wherein the spigot is rotatably mounted around a shaft, and In an earthquake-resistant saddle faucet provided with a stopper for limiting a rotation angle of the faucet on a rotating contact surface of the upper saddle,
A pair of arms capable of holding the seismic saddle split faucet, one end of which is rotatably connected to the other end, and the other end of which can be fastened by a fastening member, and an opposing portion of the holding member. A pair of two insertion pieces projecting toward each other in opposite directions and can be fitted without a gap between the stopper on the faucet side of the seismic saddle faucet and the stopper on the saddle side. It is.

[0013] By inserting the insertion piece between the stoppers, both forward and reverse rotations are prevented, thereby saving labor in drilling and pulling out the tool. Further, since the insertion piece is supported by the holding member composed of a pair of two arm members, the handling is simple.

According to a second aspect of the present invention, there is provided an anti-rotation jig for a seismic-resistant saddle dispenser, wherein the pair of two insertion pieces according to the first aspect are rotatable relative to the holding member in a plane parallel to the opening and closing direction of the holding member. It is characterized by being pivotally supported.

[0015] Since the insertion piece is supported so as to be capable of so-called "swinging", the positional relationship between the insertion piece and the stopper is automatically adjusted when the insertion piece is inserted between the stoppers.

[0016]

Next, an embodiment of the present invention will be described. FIG. 1 is a plan view of an embodiment of the first aspect of the present invention.

In FIG. 1, reference numeral 3 denotes a holding member capable of holding an earthquake-resistant saddle dispenser 5. The holding member 3 is a pair of arms 4, 4, one end 4 A of which is rotated by a pin 7. The other ends 4B and 4B are freely connected and can be fastened by a fastening member 8 such as a bolt and nut.

A pair of two insertion pieces 9 which can be fitted without gap between the stopper 5A on the water tap side of the seismic saddle water tap 5 and the stopper 1C on the saddle side are provided at the opposing portion of the holding member 3. They are configured so as to protrude toward each other.

In the above, the pair of arms 4 and 4 constituting the holding member 3 have strength enough to support the insertion piece 9 and to oppose the force by which the insertion piece 9 is pushed out when sandwiched between the stoppers 5A and 1C. If it has this strength, it can be made of metal, aluminum light alloy, or plastic.

The arms 4 and 4 have a curved shape as shown in the drawing because the insertion pieces 9 need to be inserted into and supported by the rotation stopper 5A and the saddle-side stopper 1C of the water faucet 5.

Although the fastening member 8 is a bolt and nut, a T-head bolt may be used as shown in the figure for convenience of handling. The insertion piece 9 has a strength that can withstand the compressive force generated by the rotating force of the drill between the stoppers 5A and 1C.
It is made of metal, aluminum light alloy, hard plastic, etc.

FIG. 2 is a plan view showing an embodiment of an anti-rotation jig of the seismic saddle water tap according to the present invention.
Is supported by a pin 9A so as to be rotatable with respect to the holding member 3 in a plane parallel to the opening and closing direction of the holding member 3 as indicated by an arrow.

Next, the use state of the jig for preventing rotation of the seismic saddle faucet will be described. After attaching the seismic saddle water tap 1 to the water pipe 2 as shown in FIG. 5, the cap 5E of the water tap 5 is removed, and a drill (not shown) is inserted to pierce the water pipe 2. Prior to this, the arm 4 of the rotation preventing jig is opened as shown by the dotted line in FIG. 1, the insertion pieces 9 and 9 are positioned at the stopper portion of the water tap 5, and the arm 4 is closed and fastened so as to sandwich the water tap 5. The other end 4B of the arm is fastened by the member 8.

Accordingly, the insertion pieces 9, 9 are fitted between the stoppers 5A and 1C as shown in FIG. 3 to prevent relative rotation. After that, the piercing drill is driven to pierce, and after the piercing, the piercing tool is pulled out and the operation is completed.

After that, when the rotation preventing jig is removed, the stopper 5A of the water tap 5 and the saddle side stopper 1C are in the neutral position as shown in FIG. Therefore, if there is a change in the ground due to an earthquake or the like, the water faucet 5 rotates and the stress generated in the pipe is alleviated, so that the mounting portion, the branch pipe and the like are prevented from being broken.

[0026]

As described above, according to the jig for preventing rotation of the seismic saddle faucet of the present invention, the stopper provided at the neck portion where the faucet and the saddle are attached after the saddle faucet is mounted. Just by fitting the parts, the free rotation of the saddle faucet is prevented, and the danger of co-rotation during drilling and the deformation or chipping of the stopper due to the collision of the stoppers can be prevented.

Further, since there is no need to perform operations such as adjusting the rotation of the water faucet, there is an effect that the mounting operation can be performed quickly.
