Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an anti-rotation jig for an earthquake-resistant saddle water faucet.
[0002]
[Prior art]
A saddle water faucet 1 as shown in FIG. 4 is used as a water faucet for branching a water supply pipe from a water distribution pipe to each demand home.
[0003]
The saddle water faucet 1 is composed of a semicircular upper saddle 1A and a semicircular lower saddle 1B along the outer periphery of the water distribution pipe 2 (FIG. 5), and the water faucet 5 is attached to the upper saddle 1A. The saddle is fastened with a fastener 6 such as a bolt and nut.
[0004]
By the way, since the saddle water faucet 1 is attached to the outer periphery of the water pipe 2, it becomes a protrusion on the outer periphery of the water pipe 2.
Further, the saddle water faucet 1 is usually buried underground together with the water distribution pipe 2.
[0005]
For this reason, when there is a ground change due to an earthquake or the like, the saddle water faucet 1 is easily affected, and there is a problem that a water leakage accident is likely to occur.
In addition, since such water leakage accidents occur all at once in the vicinity of the earthquake, a large amount of water is wasted due to the water leakage, and there is a problem that requires a lot of labor and time for the subsequent restoration.
[0006]
Therefore, for the purpose of solving the above-mentioned problem, the water faucet 5 is attached to the upper saddle so as to be rotatable around the shaft, and the external force is released by rotating it when an external force is applied. Has been proposed (Japanese Patent Application No. 9-9839).
[0007]
However, when the water intake hole 2A is drilled in the water distribution pipe 2, the cap 5E is removed, and the drill (not shown) of the drilling tool is inserted through the water tap 5 so that the water tap 5 serves as the drill. There was a problem that would be dangerous during the drilling operation.
[0008]
Therefore, when the water intake hole is drilled in the water distribution pipe, the end view taken along the line XX in FIG. 5 is as shown in FIG. A stopper 5A and a stopper 1C are provided on the water faucet side and the saddle side, respectively, and a seismic saddle water faucet that can be installed safely and easily and has the same seismic function after installation is proposed. ing.
[0009]
[Problems to be solved by the invention]
However, although the rotation at the time of drilling can be prevented by the earthquake-resistant saddle water faucet having the above configuration, a gap indicated by θ is provided between the stopper 5A of the water faucet 5 and the saddle side stopper 1C as shown in FIG. When drilling from a certain state, the water faucet rotates by a gap of θ due to rotation with the drill, and the stoppers 5A and 1C may collide violently.
[0010]
In order to avoid this, as shown in FIG. 7, prior to drilling, the water faucet is rotated in the rotation direction of the drill in advance so that the stoppers are brought into contact with each other and the drilling drill is driven. It is necessary to rotate the stoppers in the opposite direction until they come into contact with each other and rotate them in the direction of the drill removal rotation. After the drill is pulled out again, rotate the water faucet to the neutral position as shown in FIG. There was a problem that handling was troublesome, such as the need to return.
[0011]
In order to solve the above problems, the present invention provides an earthquake-resistant saddle water faucet provided with a stopper so that it does not rotate with the drill when drilling. It was made for the purpose of providing an anti-rotation jig for an earthquake-resistant saddle water faucet that can prevent rotation.
[0012]
[Means for Solving the Problems]
That is, the anti-rotation jig for the earthquake-resistant saddle water faucet according to claim 1 has the water faucet rotatably attached to the periphery of the shaft, and the rotational contact surface between the water faucet and the upper saddle. The seismic saddle water faucet provided with a stopper for limiting the rotation angle of the water faucet is a pair of arms that can hold the seismic saddle water faucet, with one end pivotably connected to each other. A clamping member whose other end can be fastened by a fastening member, and a water faucet side stopper and a saddle side stopper of the earthquake-resistant saddle water faucet that protrude in opposite directions at opposing portions of the clamping member It consists of two pairs of insertion pieces which can be inserted with no gap between them.
[0013]
By inserting the insertion piece between the stoppers, both forward and reverse rotations are prevented, and labor is saved during drilling and tool extraction.
Moreover, since the insertion piece is supported by the clamping member which consists of a pair of arm member, handling becomes also easy.
[0014]
The anti-rotation jig for the earthquake-resistant saddle water faucet according to claim 2 is configured such that the two pairs of insertion pieces of claim 1 can rotate with respect to the clamping member in a plane parallel to the opening / closing direction of the clamping member. It is characterized by being pivotally supported.
[0015]
Since the insertion piece is supported so as to perform so-called “swing”, the positional relationship between the insertion piece and the stopper is automatically adjusted when the insertion piece is inserted between the stoppers.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described.
FIG. 1 is a plan view of an embodiment of the invention of claim 1.
[0017]
In FIG. 1, reference numeral 3 denotes a clamping member that can clamp the earthquake-resistant saddle dispensing tap 5, and the clamping member 3 is a pair of arms 4, 4, and one end 4 </ b> A is rotatably connected by a pin 7. The other ends 4B and 4B can be fastened with fastening members 8 such as bolts and nuts.
[0018]
Then, two pairs of insertion pieces 9 that can be fitted between the water faucet stopper 5A of the earthquake-resistant saddle water faucet 5 and the saddle side stopper 1C in the opposing portion of the clamping member 3 in the opposing direction. Projected toward
[0019]
In the above, as long as the pair of arms 4 and 4 constituting the holding member 3 support the insertion piece 9 and have a strength capable of resisting 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.
[0020]
The arms 4 and 4 have a curved shape as shown in the figure because the insertion piece 9 needs to be inserted into and supported by the rotation stopper 5A and saddle side stopper 1C of the water faucet 5.
[0021]
Although the fastening member 8 is a bolt and nut, a T-head bolt may be used as shown in the figure for ease of handling.
The insertion piece 9 is made strong enough to withstand the compressive force generated by the rotational force of the drill drill between the stoppers 5A and 1C, and is made of metal, aluminum light alloy, hard plastic, or the like.
[0022]
FIG. 2 is a plan view of an embodiment of the anti-rotation jig for the earthquake-resistant saddle water faucet of claim 2, and the insertion piece 9 is in a plane parallel to the opening / closing direction of the clamping member 3 with respect to the clamping member 3. As shown by the arrow, it is supported by a pin 9A so as to be rotatable.

As shown in FIG. 5, after attaching the earthquake-resistant saddle water faucet 1 to the water distribution pipe 2, the cap 5E of the water faucet 5 is removed, and a perforation drill (not shown) is inserted to perforate the water distribution pipe 2. Prior to this, the arm 4 of the anti-rotation 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 arm other end 4B is fastened by the member 8.
[0024]
Accordingly, the insertion pieces 9 and 9 are fitted between the stoppers 5A and 1C as shown in FIG. 3 to prevent relative rotation.
Thereafter, the drilling drill is driven to perform drilling, and after drilling, the drilling tool is pulled out and the operation is completed.
[0025]
Thereafter, when the rotation preventing jig is removed, the stopper 5A and the saddle side stopper 1C of the water faucet 5 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 to relieve the stress generated in the pipe and prevent the attachment part, the branch pipe and the like from being broken.
[0026]
【The invention's effect】
As described above, according to the earthquake-resistant saddle water faucet rotation prevention jig of the present invention, after the saddle water faucet is attached, it is fitted to the stopper portion provided at the neck portion where the water faucet and the saddle are attached. As a result, free rotation of the saddle water faucet is prevented, and dangers due to rotation during drilling by a drill, and deformation or chipping of the stopper due to collision of the stoppers can be prevented.
[0027]
Further, since the operation such as the rotation adjustment of the water faucet is unnecessary, there is an effect that the attaching operation can be performed quickly.
