When the structure of Patent Document 1 is applied to the joint pedestal, a long moving hole is formed in the pedestal body in the center line direction (vertical direction) of the through hole in the partition plate, and the transparent hole is branched from the moving hole. A plurality of locking holes extending in the circumferential direction (horizontal direction) of the holes are formed at equal intervals in the center line direction. It should be noted that a downwardly recessed locking portion is formed at the tip of each locking hole in the extending direction. On the other hand, the slider is provided with a shaft portion penetrating the moving hole, and the shaft portion can be displaced in the moving hole and the locking hole. A locking screw is attached to the end of the shaft to prevent the shaft from slipping out of the moving hole.

According to this structure, the slider (shaft portion) is moved to a position corresponding to a predetermined locking hole in the direction in which the moving hole extends (vertical direction). After that, the slider is moved in the circumferential direction (horizontal direction) of the through hole so that the shaft portion is inserted into the locking hole, and the shaft portion is dropped into the locking portion of the locking hole, so that the slider moves in the vertical direction. Position, in other words, the position in the vertical direction of the sprinkler head is determined. Therefore, depending on whether the slider (shaft) is moved along the moving hole and the locking hole and the shaft is dropped into the locking portion of any one of the locking holes, the vertical direction of the sprinkler head The position can be adjusted.

When the structure of Patent Document 2 is applied to the joint pedestal, the pedestal body is provided with a feed screw shaft extending in the center line direction (vertical direction) of the through hole in the partition plate. On the other hand, the slider is connected to a nut that is screwed onto the feed screw shaft and is prevented from rotating integrally with the rotation of the feed screw shaft.

According to this structure, by rotating the feed screw shaft, the nut is displaced in the axial direction (vertical direction) of the feed screw shaft, and the slider connected to the nut is displaced in the axial direction of the feed screw shaft. To do. Therefore, by rotating the feed screw shaft, the position of the sprinkler head connected to the second end of the joint in the vertical direction is adjusted.

Hereinafter, one embodiment of the joint pedestal will be described with reference to FIGS. 1 to 4.
As shown in FIG. 1, the joint pedestal 1 is provided between a partition plate 3 installed at a predetermined distance from the construction surface 2 and the construction surface 2 and includes, for example, a water supply pipe 4 and a sprinkler head 5. It is used when installing the joint 6 that connects the members. The water supply pipe 4 is connected to the first end 6a of the joint 6 via another joint 15, and the sprinkler head 5 is connected to the second end 6b of the joint 6. A cap 25 for protecting the sprinkler head 5 is attached to the sprinkler head 5. On the other hand, the partition plate 3 is formed with a through hole 22 for exposing a part of the sprinkler head 5 connected to the second end 6b of the joint 6.

The joint pedestal 1 includes a pedestal body 8 attached to the construction surface 2 with fixing bolts 7. The pedestal body 8 is provided with a protruding portion 9 extending in a direction protruding from the construction surface 2. A long hole 10 that is long in the projecting direction of the projecting portion 9 is formed in the projecting portion 9, and a slider 11 for supporting the joint 6 is movably held.

The slider 11 includes a holding portion 12 formed integrally with the joint 6, and a shaft portion 13 protruding from the holding portion 12 and penetrating the elongated hole 10 and capable of being displaced in the elongated hole 10. , A butterfly bolt 14 screwed into an end portion of the shaft portion 13 opposite to the holding portion 12 side. A screw hole 23 into which the butterfly bolt 14 is screwed is formed in the shaft portion 13 and the holding portion 12. The screw hole 23 extends in a direction (left-right direction in FIG. 1) orthogonal to the protruding direction of the protruding portion 9 of the base body 8.

Incidentally, the elongated hole 10 formed in the protruding portion 9 functions as a through hole through which the shaft portion 13 penetrates. The shaft portion 13 is movable in the elongated hole 10 in the longitudinal direction of the elongated hole 10. Further, the holding portion 12 for supporting the joint 6 is connected to one end portion (the left end portion in FIG. 1) of the shaft portion 13. Further, the head portion of the butterfly bolt 14 connected to the other end portion (right end portion in FIG. 1) of the shaft portion 13 functions as a locking portion that prevents the shaft portion 13 from coming out of the elongated hole 10.

The holding portion 12 of the slider 11 is formed with a screw hole 24 extending in the protruding direction of the protruding portion 9 of the pedestal body 8 and penetrating the holding portion 12. The screw hole 24 intersects with the screw hole 23. Then, a bolt 16 is screwed toward the construction surface 2 at a portion of the screw hole 24 opposite to the construction surface 2. Under the condition that the bolt 16 is screwed into the screw hole 24, the tip of the threaded portion 16c of the bolt 16 projects from the portion of the holding portion 12 on the construction surface 2 side. Further, the tip portion of the screw portion 16c is flattened by a punch or the like, so that the tip portion is expanded in diameter with respect to the inner diameter of the screw hole 24.

A hexagonal hole 16b is formed in the head 16a of the bolt 16. Then, by rotating the bolt 16 around its center line with the tool inserted in the hexagonal hole 16b, the bolt 16 is displaced in the center line direction with respect to the holding portion 12, With the displacement, the head 16a of the bolt 16 moves toward and away from the holding portion 12. The tip of the threaded portion 16c of the bolt 16 that has a larger diameter than the inner diameter of the screw hole 24 functions as a retainer for the bolt 16 from the screw hole 24, and excessively turns in the direction of loosening the bolt 16. The bolt 16 is prevented from falling out of the screw hole 24 when it is dynamically operated.

On the pedestal 1 for the joint, the slider 11 is pressed in the extending direction of the shaft portion 13 on the basis of the rotating operation of the bolt 16, whereby the slider 11 (the holding portion 12 or the head portion of the butterfly bolt 14) is projected from the pedestal body 8. A fixing member 17 that presses and fixes the portion 9 is provided. The fixing member 17 is provided on the first plate 18 arranged in the gap between the projecting portion 9 of the pedestal body 8 and the holding portion 12 of the slider 11, and the end portion (the lower end portion in FIG. 1) of the first plate 18. The 2nd plate 19 connected is provided.

In the first plate 18 of the fixing member 17, the width in the direction orthogonal to the longitudinal direction of the elongated hole 10 and the direction in which the shaft portion 13 extends is larger than the width of the elongated hole 10 in that direction. At the end of the first plate 18 opposite to the end on the second plate 19 side, a recess 21 for accommodating the shaft portion 13 so as to sandwich the shaft portion 13 in the radial direction is formed. Further, the second plate 19 of the fixing member 17 is arranged outside the gap between the projecting portion 9 and the holding portion 12, is inclined with respect to the first plate 18, and is held by the head 16 a of the bolt 16. A gap is provided between the holding portion 12 and the holding portion 12 in the approaching/separating direction with respect to the portion 12. Further, the second plate 19 has an insertion portion 20 (a hole in this example) for inserting the screw portion 16c of the bolt 16.

When the head 16a of the bolt 16 approaches the holding portion 12 based on the turning operation of the bolt 16 in the tightening direction, the second plate 19 causes the edge portion of the holding portion 12 near the end of the first plate 18. The P1 pivots about a fulcrum, and accordingly, the first plate 18 presses the head portion of the butterfly bolt 14 and the protruding portion 9 in the extending direction of the shaft portion 13. Specifically, when the first plate 18 is pressed by the protruding portion 9, the fixing member 17 presses the holding portion 12 in the direction in which the shaft portion 13 extends in the direction away from the protruding portion 9. As the holding portion 12 is pressed in the direction away from the protruding portion 9 in this manner, the head portion of the butterfly bolt 14 connected to the shaft portion 13 is pressed against the protruding portion 9 in the extending direction of the shaft portion 13, thereby causing the slider to move. 11 (joint 6) is fixed to the pedestal body 8 (projection 9).

On the other hand, when the head portion 16a of the bolt 16 is separated from the holding portion 12 based on the turning operation of the bolt 16 in the loosening direction, the second plate 19 causes the edge portion P1 of the holding portion 12 near the end portion of the first plate 18. With respect to the fulcrum, rotation in the opposite direction to the above-described rotation is allowed. As a result, the pressing of the head portion of the wing bolt 14 and the protruding portion 9 by the first plate 18 in the extending direction of the shaft portion 13 is released. Specifically, when the pressing of the first plate 18 against the protruding portion 9 is released, the fixing member 17 also releases the pressing of the holding portion 12 in the direction in which the shaft portion 13 extends in the direction away from the protruding portion 9. When the pressing is released, the head of the butterfly bolt 14 connected to the shaft 13 is also released from being pressed by the protrusion 9 in the extending direction of the shaft 13. As a result, the fixing of the slider 11 (joint 6) to the pedestal body 8 (projection 9) is also released, and the slider 11 slides in the longitudinal direction of the slot 10 or rotates around the center line of the shaft 13. It becomes possible.

Note that FIG. 2 shows a state in which the joint pedestal 1 is viewed from the through hole 22 side of the partition plate 3. As can be seen from the figure, the bolt 16 of the joint pedestal 1 is arranged so as to overlap the through hole 22 in the center line direction of the through hole 22.

Next, a procedure for installing the joint 6 using the joint pedestal 1 will be described.
In FIG. 1, the pedestal body 8 of the joint pedestal 1 is attached to the construction surface 2 with the fixing bolts 7 before the partition plate 3 is installed. After that, the shaft portion 13 of the slider 11 is passed through the elongated hole 10 of the pedestal body 8 (projection portion 9 ), and the butterfly bolt 14 is screwed into the threaded hole 23 of the shaft portion 13 to some extent. It should be possible to move relative to.

FIG. 3 shows a state in which the slider 11 is lowered to the lowest point with respect to the protruding portion 9 of the pedestal body 8 by its own weight. At this time, the first plate 18 is rotated and inclined so that a gap is formed between the first plate 18 and the holding portion 12 with the edge portion P1 of the holding portion 12 near the end of the first plate 18 serving as a fulcrum. That is, the screw portion 16c of the bolt 16 is screwed into the screw hole 24 so that the first plate 18 is in such a state.

After that, the position of the joint 6 is adjusted to an appropriate position (position in FIG. 1) through the relative movement of the slider 11 with respect to the protruding portion 9 of the base body 8, and the butterfly bolt 14 is tightened at that position. When the wing bolt 14 is tightened in this manner, the head of the wing bolt 14 and the protrusion 9 are pressed in the extending direction of the shaft portion 13 with the first plate 18 having a gap between the first plate 18 and the holding portion 12. Then, the slider 11 is fixed to the projecting portion 9 by the pressing.

When the slider 11 (joint 6) is fixed to the projecting portion 9 as described above, if the bolt 16 on the holding portion 12 of the slider 11 is rotated in the direction of loosening, the head 16a of the bolt 16 is removed. The slider 11 is separated from the holding portion 12, and the fixation of the slider 11 to the protruding portion 9 by the pressing of the first plate 18 is released. As a result, it becomes possible to move the slider 11 relative to the protrusion 9.

Now, as described above, after the slider 11 is fixed to the projecting portion 9 of the pedestal body 8 by tightening the butterfly bolt 14, the partition plate 3 is installed at a predetermined distance from the construction surface 2. When the partition plate 3 is installed in this manner, a part of the sprinkler head 5 connected to the second end 6b of the joint 6 is exposed from the through hole 22 of the partition plate 3. That is, as described above, by adjusting the position of the joint 6 to an appropriate position through the relative movement of the slider 11 with respect to the projecting portion 9, a part of the sprinkler head 5 is removed from the through hole 22 when the partition plate 3 is installed. Exposed.

However, when the partition plate 3 is installed, the sprinkler head 5 is inserted into the through hole 22 due to an incorrect fixing position of the slider 11 with respect to the protruding portion 9 or an error in the installation position of the partition plate 3. There is a case in which the sprinkler head 5 cannot be properly exposed from the through hole 22 because it is not in the proper relative position. In this case, the position of the slider 11 (joint 6) is properly readjusted so that the sprinkler head 5 is located at an appropriate position as follows.

That is, as shown in FIG. 4, the hexagonal wrench 31 is inserted into the hexagonal hole 16b of the head 16a of the bolt 16 in the slider 11 (holding portion 12) through the through hole 22 of the partition plate 3, and the hexagonal wrench 31 in that state is inserted. The wrench 31 is used to rotate the bolt 16 in a loosening direction. As a result, the bolt 16 is displaced in the direction of its center line, and the head portion 16a of the bolt 16 is separated from the holding portion 12 accordingly. When the head portion 16a of the bolt 16 is separated from the holding portion 12, the second plate 19 is separated from the holding portion 12 with the edge portion P1 of the holding portion 12 near the end of the first plate 18 as a fulcrum. It becomes possible to rotate. As a result, the pressing of the slider 11 (the head of the wing bolt 14) and the projecting portion 9 of the pedestal body 8 in the extending direction of the shaft portion 13 by the first plate 18 is released, and thus the slider 11 is fixed to the projecting portion 9. Is released.

Under such a state where the slider 11 is released, by directly operating the slider 11 through the through hole 22 of the partition plate 3, more specifically, by raising and lowering the slider 11 with the hexagon wrench 31. The slider 11 can be freely moved within a range in which the shaft portion 13 can be displaced within the elongated hole 10. Then, after adjusting the position of the slider 11 (joint 6) so that a part of the sprinkler head 5 connected to the second end 6b of the joint 6 is exposed from the through hole 22, the bolt in the tightening direction with the hexagon wrench 31 is adjusted. The head 16 a of the bolt 16 is brought closer to the holding portion 12 through the turning operation of the bolt 16. As a result, the second plate 19 rotates about the edge portion P1 of the holding portion 12 near the end of the first plate 18 as a fulcrum, and the first plate 18 extends through the slider 11 and the protruding portion 9 of the shaft portion 13. Press in the direction. Then, with this pressing, the head portion of the wing bolt 14 of the slider 11 is pressed against the protruding portion 9 of the base body 8.

After the position of the slider 11 is fixed in this way, the cap 25 is removed from the sprinkler head 5 connected to the second end 6b of the joint 6, and the sealing plate 26 is attached to the sprinkler head 5 as shown by a chain double-dashed line in FIG. Is attached. The sealing plate 26 protects the sprinkler head 5 and, when water is discharged from the head 5, prevents the water from entering between the partition plate 3 and the construction surface 2 through the through hole 22. It is for.

Next, the operation and effect of the joint base 1 will be described.
After the partition plate 3 is installed at a predetermined distance from the construction surface 2 to which the pedestal body 8 is attached, a part of the sprinkler head 5 connected to the second end 6b of the joint 6 is passed through the through hole 22 of the partition plate 3. When it becomes necessary to adjust the fixing position of the slider 11 (joint 6) with respect to the protruding portion 9 of the pedestal body 8 so as to expose it from above, the adjustment can be performed easily and promptly.

That is, when adjusting the fixing position of the slider 11, the fixing of the slider 11 is released by rotating the bolt 16 in the holding portion 12 with the hexagon wrench 31 through the through hole 22 of the partition plate 3. To be done. When the slider 11 is released in this manner, the slider 11 is directly operated through the through hole 22 so that the shaft portion 13 can be displaced within the elongated hole 10 of the slider 11. Can be moved freely. Therefore, the slider 11 can be easily and quickly moved relative to the protruding portion 9 of the pedestal body 8, and the fixed position of the slider 11 can be easily and quickly adjusted through the movement of the slider 11. Become.

The above embodiment can be modified as follows, for example.
As shown in FIG. 5, the first plate 18 of the fixing member 17 may be arranged in the gap between the protrusion 9 of the pedestal body 8 and the head of the butterfly bolt 14 of the slider 11. In this case, the second plate 19 of the fixing member is connected to the end of the first plate 18 while penetrating the elongated hole 10 of the protruding portion 9. In addition, in the second plate 19 of this example, the width is narrowed so as to be able to penetrate the elongated hole 10, while the insertion portion 20 is formed so that the insertion portion 20 can be formed even if the width is reduced. Not a cutout.

With this structure, when the head 16a of the rotated bolt 16 approaches the holding portion 12, the second plate 19 rotates around the edge portion P1 of the holding portion 12 near the end of the first plate 18 as a fulcrum. The first plate 18 is pressed against the head of the wing bolt 14 accordingly. As a result, the fixing member 17 presses the butterfly bolt 14 in the direction in which the shaft portion 13 extends in the direction away from the protruding portion 9, and the holding portion 12 connected to the butterfly bolt 14 via the shaft portion 13 is pressed against the protruding portion 9. It As a result, the slider 11 (joint 6) is fixed to the pedestal body 8 (protrusion 9).

On the other hand, when the head portion 16a of the bolt 16 which is rotated is separated from the holding portion 12, the second plate 19 is rotated about the edge portion P1 of the holding portion 12 near the end portion of the first plate 18 as a fulcrum. Is allowed to rotate in the opposite direction. As a result, the pressing of the first plate 18 against the head portion of the wing bolt 14 is released, and thus the fixing member 17 also releases the pressing of the holding portion 12 against the protruding portion 9 in the extending direction of the shaft portion 13. As a result, the fixation of the slider 11 (joint 6) to the pedestal body 8 (protrusion 9) is released, and the slider 11 can freely move within the range in which the shaft 13 can be displaced within the elongated hole 10. Become.

As shown in FIG. 6, the portion of the joint 6 near the first end 6a may be inclined with respect to the construction surface 2 so as to approach the construction surface 2 as it approaches the first end 6a. In this case, even when the water supply pipe 4 is arranged on the construction surface 2 and the joint 6 is fixed at a position apart from the construction surface 2, the joint pipe 6 is not bent with a large curvature. Can be connected to the first end 6a of the.

As shown in FIGS. 7 to 9, the joint 6 may be provided with a guide portion 27 that guides the position of the bolt 16 (operation member). The joint 6 at this time plays a role as a joint body supported by the slider and provided with a guide portion. As shown in FIG. 7, the guide portion 27 is provided so as to project from the surface of the second end 6b of the joint 6 on the bolt 16 side. In addition, the guide portion 27 has a concave curved surface 28 formed at a position visible through the through hole 22. The concave curved surface 28 is formed at the tip of the guide portion 27 in the protruding direction, and is curved in the circumferential direction of the screw portion 16c (FIGS. 8 and 9) of the bolt 16. Further, the concave curved surface 28 is formed so as to appear to surround the left half of the hexagonal hole 16b of the bolt 16 in FIG. The concave curved surface 28 extends in the axial direction of the bolt 16 (the vertical direction in FIG. 8), as shown in FIG.

FIG. 8 shows a state in which the slider 11 is lowered to its lowest point with respect to the protruding portion 9 of the base body 8 by its own weight. Under this condition, the position of the joint 6 is adjusted to an appropriate position through the relative movement of the slider 11 with respect to the protruding portion 9 of the pedestal body 8, and the butterfly bolt 14 is tightened at that position so that the slider 11 protrudes. Fixed against. Then, as shown in FIG. 9, the partition plate 3 is installed at a predetermined distance from the construction surface 2.

When the position of the slider 11 (joint 6) is properly readjusted after the partition plate 3 is installed, as shown in FIG. 9, the slider 11 (holding portion 12) is inserted through the through hole 22 of the partition plate 3. The hexagonal wrench 31 is inserted into the hexagonal hole 16b of the head 16a of the bolt 16, and the bolt 16 is rotated using the hexagonal wrench 31 in this state. When the hexagonal wrench 31 is inserted into the hexagonal hole 16b to rotate the bolt 16 in this way, the guide portion 27 guides the position of the hexagonal hole 16b in the bolt 16 as follows.

That is, the concave curved surface 28 of the guide portion 27 serves as a mark, and the position of the hexagonal hole 16b can be easily confirmed by visual inspection of the concave curved surface 28, so that the hexagonal wrench 31 can be easily inserted into the hexagonal hole 16b. Further, by inserting the hexagon wrench 31 inside the concave curved surface 28, and moving the hexagon wrench 31 along the concave curved surface 28 in the extending direction of the concave curved surface 28 (axial direction of the bolt 16) in this state, The wrench 31 can be easily inserted into the hexagonal hole 16b.

As can be seen from the above, the guide for the position of the bolt 16 by the guide portion 27 is the display of the mark that facilitates the visual confirmation of the position of the bolt 16 (hexagonal hole 16b) and the head 16a of the bolt 16. This means that the hexagon wrench 31 is easily made to face the operation position of the bolt 16 (the position of the hexagonal hole 16b) by the shape of the concave curved surface 28 located on the periphery. Even if the hexagon wrench 31 has to be inserted into the hexagonal hole 16b by inserting the hexagonal wrench 31 into a narrow space between the inner wall of the through hole 22 and the outer wall of the second end 6b by the guide of the position of the bolt 16 by the guide portion 27. The insertion can be facilitated and the bolt 16 can be easily rotated by using the hexagon wrench 31.

The guide for the position of the bolt 16 by the guide portion 27 may be only the display of a mark that facilitates the visual confirmation of the position of the bolt 16 (hexagonal hole 16b). In this case, for example, it is conceivable to provide a recessed portion with a punch or the like at a portion of the second end 6b of the joint 6 shown in FIG. 2 on the bolt 16 side and corresponding to the hexagonal hole 16b, and use the recessed portion as a guide portion. To be Further, in order to make the concave portion conspicuous, a paint or an animal paint may be put in the concave portion. In addition, the portion of the second end 6b on the side of the bolt 16 that corresponds to the hexagonal hole 16b is marked with a paint or a live paint without forming the above-mentioned recessed portion, and the portion is marked with the guide portion. You may make it function as.

8 and 9, the bolt 16 is further lengthened so that the bolt 16 extends from the holding portion 12, so that the head 16a of the bolt 16 reaches the concave curved surface 28 of the guide portion 27. You may do it. In this case, it is preferable that a cylindrical spacer is provided between the head 16a of the bolt 16 and the second plate 19 of the fixing member 17, and the threaded portion 16c of the bolt 16 penetrates the spacer.

As described above, if the head portion 16a of the bolt 16 reaches the concave curved surface 28 of the guide portion 27, the hexagon wrench 31 is inserted inside the concave curved surface 28 so that the head portion at the operating position of the bolt 16 is located. The hexagon wrench 31 can be easily exposed to the 16a (hexagonal hole 16b). Further, by providing the spacer, the second plate 19 is pushed by the spacer when the head 16a of the bolt 16 is brought closer to the holding portion 12 through the rotating operation. Therefore, even if the head 16a of the bolt 16 reaches the concave curved surface 28 of the guide portion 27, even if the head 16a of the bolt 16 extends from the holding portion 12, the head 16a of the bolt 16 approaches the holding portion 12. By doing so, the second plate 19 can be pressed.

Instead of providing the spacer, the head 16a is provided with a protrusion that projects toward the second plate 19 and hits the second plate 19, or the second plate 19 projects toward the head 16a and hits the head 16a. You may provide a protrusion. By the way, if the spacers are provided, it is not necessary to provide the protrusions, so that the head portion 16a of the bolt 16 with respect to the holding portion 12 does not have to be complicated in shape of the head portion 16a and the second plate 19. The second plate 19 can be pressed by approaching.

8 and 9, the guide portion 27 and the concave curved surface 28 are extended to the holding portion 12 side so that the head 16a of the bolt 16 reaches the concave curved surface 28, and the guide portion 27 and the concave curved surface 28 of the joint 6 are provided. The second end 6b provided may be further provided near the holding portion 12 so that the head portion 16a of the bolt 16 reaches the concave curved surface 28.

The bolt 16 may be prevented from coming off from the screw hole 24 by providing a split pin at the tip of the bolt 16 instead of flattening the tip of the threaded portion 16c.

-As the joint 6, an example in which two members of the water supply pipe 4 and the sprinkler head 5 are connected has been illustrated, but two members other than the water supply pipe 4 and the sprinkler head 5 may be connected. In this case, the construction surface 2 to which the pedestal body 8 of the joint pedestal 1 is attached does not necessarily have to be a horizontal surface, and may be a surface other than a horizontal surface such as a vertical surface.

Next, the technical idea that can be understood from the above embodiment will be described.
(A) In a joint including a pedestal attached to a construction surface, a slider movably held on the pedestal, and a joint body supported by the slider, the slider is a penetrating hole formed in the pedestal. A shaft portion that penetrates through the hole and is capable of displacement within the through hole, a holding portion that is connected to one end portion of the shaft portion and supports the joint body, and the other end portion of the shaft portion. And a locking portion for preventing the shaft portion from coming off from the through hole, and the holding portion of the slider is provided with an operation member that is rotated. A fixing member is provided for pressing the slider in the direction in which the shaft extends based on the rotating operation of, and thereby fixing and holding the holding portion or the locking portion against the pedestal.
