Such a joint base is used when installing a joint that connects two members such as a water supply pipe and a sprinkler head between a partition plate installed at a predetermined distance from the construction surface and the construction surface.

  In this case, while the water supply pipe is connected to the first end of the joint, the sprinkler head is connected to the second end of the joint. Then, after the pedestal main body is attached to the construction surface, the position of the sprinkler head connected to the second end of the joint is properly adjusted through the relative movement of the slider relative to the pedestal main body, and the slider relative to the pedestal main body at that position. Fix it. Furthermore, a partition plate is installed at a predetermined distance from the above-mentioned construction surface. The partition plate is formed with a through hole for exposing a portion of the sprinkler head connected to the second end of the joint when installed as described above.

  Incidentally, as a structure for adjusting the position of the sprinkler head connected to the second end of the joint through the relative movement of the slider with respect to the pedestal main body, for example, the structures shown in Patent Documents 1 and 2 can be mentioned.

  When the structure of Patent Document 1 is applied to a joint pedestal, a long moving hole is formed in the pedestal main body in the direction of the center line (vertical direction) of the through hole in the partition plate, and branches 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. In addition, the latching | locking part dented below is formed in the front-end | tip part of the extension direction of each locking hole. 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. Further, a locking screw for preventing the shaft from coming off from the moving hole is attached to the end of the shaft.

  According to this structure, the slider (shaft portion) is moved to the position corresponding to the predetermined locking hole in the extending direction (vertical direction) of the moving hole. Thereafter, 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 to vertically move the slider. Position of the sprinkler head, in other words, the position of the sprinkler head in the vertical direction. Therefore, the vertical direction of the sprinkler head is determined by moving the slider (shaft) along the moving hole and the locking hole and dropping the shaft into the locking portion of one of the locking holes. You can adjust the position of.

  Moreover, when the structure of patent document 2 is applied to the base for couplings, the base body is provided with the feed screw shaft extended in the centerline direction (vertical direction) of the through-hole in a partition plate. On the other hand, the slider is connected to a nut screwed to the feed screw shaft, and is not integrally rotated 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 Do. Therefore, by rotating the feed screw shaft, the vertical position of the sprinkler head connected to the second end of the joint is adjusted.

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

  The joint base 1 includes a base body 8 attached to the work surface 2 by a fixing bolt 7. The pedestal main body 8 is provided with a projecting portion 9 extending in the direction of projecting from the construction surface 2. An elongated hole 10 is formed in the projecting portion 9 in a direction in which the projecting portion 9 projects, and a slider 11 for supporting the joint 6 is movably held.

  The slider 11 has a holding portion 12 integrally formed with the joint 6, and a shaft portion 13 which protrudes from the holding portion 12 and penetrates the long hole 10 and can be displaced in the long hole 10. And 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 and right direction in FIG. 1) orthogonal to the projecting direction of the protrusion 9 in the pedestal main body 8.

  Incidentally, the long hole 10 formed in the projecting portion 9 functions as a through hole through which the shaft portion 13 penetrates. The shaft portion 13 can move in the longitudinal direction of the elongated hole 10 in the elongated hole 10. The holding portion 12 for supporting the joint 6 is connected to one end (left end in FIG. 1) of the shaft portion 13. The head of the wing bolt 14 connected to the other end (right end in FIG. 1) of the shaft 13 functions as a locking portion for preventing the shaft 13 from coming off the long hole 10.

  The holding portion 12 of the slider 11 is formed with a screw hole 24 which extends in the protruding direction of the projecting portion 9 of the pedestal main body 8 and penetrates the holding portion 12. The screw hole 24 intersects with the screw hole 23. Then, a bolt 16 is screwed into a portion of the screw hole 24 opposite to the work surface 2 toward the work surface 2. In the state where the bolt 16 is screwed into the screw hole 24, the tip end of the screw portion 16 c of the bolt 16 protrudes from the portion of the holding portion 12 on the side of the work surface 2. Furthermore, the tip end portion of the screw portion 16c is flattened by punching or the like, whereby the tip end portion is expanded in diameter with respect to the inner diameter of the screw hole 24.

  A hexagonal hole 16 b is formed in the head 16 a of the bolt 16. Then, with the tool inserted in the hexagonal hole 16b, the bolt 16 is rotated about its center line using the same tool, whereby the bolt 16 is displaced relative to the holding portion 12 in the center line direction, The head portion 16 a of the bolt 16 approaches and separates from the holding portion 12 with the displacement. A portion of the bolt 16 which is the tip of the screw portion 16c and which is larger in diameter than the inner diameter of the screw hole 24 functions as a retainer for the bolt 16 from the screw hole 24 and turns excessively in the direction of loosening the bolt 16. The bolt 16 is prevented from coming off from the screw hole 24 when moving.

  In the joint base 1, the slider 11 is pressed in the extending direction of the shaft portion 13 based on the pivoting operation of the bolt 16, whereby the slider 11 (the holding portion 12 or the head of the butterfly bolt 14) protrudes from the base body 8. A fixing member 17 is provided which is pressed and fixed to the portion 9. The fixing member 17 includes a first plate 18 disposed in a gap between the projecting portion 9 of the pedestal main body 8 and the holding portion 12 of the slider 11 and an end portion (lower end portion in FIG. 1) of the first plate 18. And a second plate 19 connected thereto.

  The width of the first plate 18 of the fixing member 17 in the direction perpendicular to the longitudinal direction of the elongated hole 10 and the extending direction of the shaft portion 13 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 is formed, which accommodates the shaft portion 13 in the radial direction. Further, the second plate 19 of the fixing member 17 is disposed outside the gap between the projecting portion 9 and the holding portion 12 and is inclined relative to the first plate 18 to hold the head 16 a of the bolt 16. A clearance is provided between the holding portion 12 and the holding portion 12 in the direction toward and away from the portion 12. Furthermore, the second plate 19 has an insertion portion 20 (a hole in this example) for inserting the screw portion 16 c of the bolt 16.

  Then, when the head portion 16 a of the bolt 16 approaches the holding portion 12 based on the pivoting operation in the tightening direction of the bolt 16, the edge portion of the second plate 19 near the end of the first plate 18 in the holding portion 12 The first plate 18 presses the head of the wing bolt 14 and the projection 9 in the direction in which the shaft 13 extends. Specifically, the first plate 18 is pressed by the projection 9 to press the holding portion 12 away from the projection 9 in the direction in which the shaft 13 extends. Thus, as the holding portion 12 is pressed in the direction away from the protruding portion 9, the head 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 the slider 11 (joint 6) is fixed to pedestal base 8 (protrusion 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 in the loosening direction of the bolt 16, the edge portion P1 of the second plate 19 near the end portion of the first plate 18 in the holding portion 12 Pivoting in the direction opposite to that described above is permitted. As a result, the pressing of the first plate 18 in the extending direction of the shaft portion 13 of the head portion of the butterfly bolt 14 and the projecting portion 9 is released. Specifically, the pressing of the first plate 18 against the projecting portion 9 is released, and the pressing of the holding portion 12 in the direction away from the projecting portion 9 in the direction in which the shaft portion 13 extends is also released. When the pressing is released, the head of the wing bolt 14 connected to the shaft 13 is also released from being pressed by the projection 9 in the direction in which the shaft 13 extends. As a result, the fixing of the slider 11 (joint 6) to the pedestal main body 8 (projecting portion 9) is also released, and the slider 11 slides in the longitudinal direction of the long hole 10 or pivots around the center line of the shaft portion 13. It is possible to

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

Next, the procedure for installing the joint 6 using the joint base 1 will be described.
In FIG. 1, the pedestal main body 8 of the joint pedestal 1 is attached to the construction surface 2 by a fixing bolt 7 before the partition plate 3 is installed. Thereafter, the shaft portion 13 of the slider 11 is passed through the long hole 10 of the pedestal main body 8 (projecting portion 9), and the butterfly bolt 14 is screwed into a screw hole 23 of the shaft portion 13 to a certain extent. It is possible to move relative to it.

  FIG. 3 shows a state in which the slider 11 is lowered to the lowest point relative to the protrusion 9 of the pedestal main body 8 by its own weight. At this time, the first plate 18 is rotated and inclined so as to have a gap with 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. That is, the screw portion 16 c of the bolt 16 is screwed into the screw hole 24 so that the first plate 18 is in such a state.

  Thereafter, through relative movement of the slider 11 with respect to the projecting portion 9 of the pedestal main body 8, the position of the joint 6 is adjusted to the proper position (the position of FIG. 1), and the butterfly bolt 14 is tightened at that position. Thus, when the wing bolt 14 is tightened, the head of the wing bolt 14 and the projecting portion 9 are pressed in the direction in which the shaft portion 13 extends, with the first plate 18 having a gap with the holding portion 12. The slider 11 is fixed to the projection 9 through the pressure.

  As described above, when the slider 11 (joint 6) is fixed to the projecting portion 9, the head portion 16a of the bolt 16 can be rotated by turning the bolt 16 in the holding portion 12 of the slider 11 in the loosening direction. After being separated from the holding portion 12, the fixing of the slider 11 to the projecting portion 9 by the pressing of the first plate 18 is released. As a result, the slider 11 can be moved relative to the protrusion 9.

  Now, as described above, after the slider 11 is fixed to the projection 9 of the pedestal main body 8 by tightening the butterfly bolt 14, the partition plate 3 is installed at a predetermined distance from the construction surface 2. Thus, when the partition plate 3 is installed, a part of the sprinkler head 5 connected to the second end 6 b of the joint 6 is exposed from the through hole 22 of the partition plate 3. That is, 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 as described above, when the partition plate 3 is installed, a part of the sprinkler head 5 Be exposed.

  However, when the partition plate 3 is installed due to an erroneous fixing position of the slider 11 with respect to the projecting portion 9 or an error in the installation position of the partition plate 3 occurring, the sprinkler head 5 faces the through hole 22. In some cases, the sprinkler head 5 can not be properly exposed through the through hole 22 because the relative position is not appropriate. In this case, the position of the slider 11 (joint 6) is appropriately readjusted so that the sprinkler head 5 is at the proper position as follows.

  That is, as shown in FIG. 4, the hexagonal wrench 31 is inserted into the hexagonal hole 16 b of the head 16 a of the bolt 16 in the slider 11 (holding portion 12) through the through hole 22 of the partition plate 3. A wrench 31 is used to turn the bolt 16 in the direction to loosen it. As a result, the bolt 16 is displaced in the direction of its center line, and the head 16 a of the bolt 16 is separated from the holding portion 12 accordingly. Then, when the head portion 16 a of the bolt 16 separates from the holding portion 12, the second plate 19 moves away 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 (head of the butterfly bolt 14) and the projection 9 of the pedestal main body 8 in the direction in which the shaft 13 is extended by the first plate 18 is released, and thus the slider 11 is fixed to the projection 9 Is released.

  As described above, under the condition that the slider 11 is released from the fixed state, the slider 11 is directly operated through the through holes 22 of the partition plate 3, and more specifically, by raising and lowering the slider 11 with the hexagonal wrench 31. The slider 11 can be freely moved within the range in which the shaft 13 can be displaced in the long 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, a bolt in a tightening direction with the hexagonal wrench 31 The head portion 16 a of the bolt 16 is made to approach the holding portion 12 through the turning operation of 16. As a result, the second plate 19 rotates about the edge P1 of the holding portion 12 near the end of the first plate 18 as a fulcrum, and the first plate 18 extends the slider 11 and the projecting portion 9 of the shaft portion Press in the direction. Then, the head of the butterfly bolt 14 in the slider 11 is pressed against the projecting portion 9 of the pedestal main body 8 in response to this pressing.

  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 6 b of the joint 6, and the sealing plate 26 is shown in FIG. Is attached. The sealing plate 26 protects the sprinkler head 5 and prevents the water from entering between the partition plate 3 and the construction surface 2 through the through holes 22 when the water is released from the head 5. It is for.

Next, the operation and effects of the joint base 1 will be described.
After installing the partition plate 3 at a predetermined distance from the construction surface 2 to which the pedestal main body 8 is attached, a part of the sprinkler head 5 connected to the second end 6 b of the joint 6 is a 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 projecting portion 9 of the pedestal main body 8 so as to expose from the 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 through the through hole 22 of the partition plate 3 with the hexagonal wrench 31. Be done. As described above, when the fixation of the slider 11 is released, by operating the slider 11 directly through the through hole 22, the range in which the displacement of the shaft portion 13 in the long hole 10 of the slider 11 is possible. Can be moved freely. Therefore, the slider 11 can be moved relative to the projection 9 of the pedestal main body 8 easily and quickly, and the movement of the slider 11 can easily and quickly adjust the fixing position of the slider 11. Become.

In addition, the said embodiment can also be changed as follows, for example.
As shown in FIG. 5, the first plate 18 of the fixing member 17 may be disposed in the gap between the protrusion 9 of the pedestal main body 8 and the head of the butterfly bolt 14 in the slider 11. In this case, the second plate 19 of the fixing member is connected to the end of the first plate 18 in a state of penetrating the long hole 10 of the protrusion 9. In the second plate 19 of this example, the width is narrowed so as to be able to penetrate the long hole 10, while the insertion portion 20 is penetrated so that the insertion portion 20 can be formed even if the width is narrowed as such. Not a notch.

  According to this configuration, when the head portion 16 a of the pivoted bolt 16 approaches the holding portion 12, the second plate 19 rotates around the edge portion P 1 of the holding portion 12 near the end of the first plate 18 as a fulcrum As it moves, the first plate 18 is pressed against the head of the butterfly bolt 14. As a result, the fixing member 17 presses the butterfly bolt 14 away from the projection 9 in the direction in which the shaft 13 extends, and the holding portion 12 connected via the butterfly bolt 14 and the shaft 13 is pressed by the projection 9 Ru. As a result, the slider 11 (joint 6) is fixed to the pedestal main body 8 (projecting portion 9).

  On the other hand, when the head portion 16a of the bolt 16 to be pivoted is separated from the holding portion 12, the second plate 19 rotates with the edge portion P1 of the holding portion 12 near the end of the first plate 18 as a fulcrum Is permitted to rotate in the reverse direction. As a result, the pressing of the first plate 18 against the head of the wing bolt 14 is released, and thus the fixing member 17 also presses the holding portion 12 against the projecting portion 9 in the direction in which the shaft portion 13 extends. Thereby, the fixing of the slider 11 (joint 6) to the pedestal main body 8 (projecting portion 9) is released, and the slider 11 can freely move within the displacable range of the shaft portion 13 in the long hole 10. Become.

  As shown in FIG. 6, the portion near the first end 6a of the joint 6 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 if the feed water pipe 4 is disposed on the work surface 2 and the joint 6 is fixed at a position away from the work surface 2, the joint 6 is not bent at a large curvature. Can be connected to the first end 6a of the

  -As shown in FIGS. 7-9, you may provide the guide part 27 which guides the joint 6 about the position of the volt | 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. The said guide part 27 is provided so that it may protrude from the surface at the side of the volt | bolt 16 in the 2nd end 6b of the coupling 6, as shown in FIG. The guide portion 27 also has a concave surface 28 formed at a position where it can be seen through the through hole 22. The concave surface 28 is formed at the tip of the guide 27 in the projecting direction, and is curved in the circumferential direction of the screw 16 c (FIGS. 8 and 9) of the bolt 16. Furthermore, the concave surface 28 is formed so as to appear in FIG. 7 so as to surround the left half of the hexagonal hole 16 b of the bolt 16. Further, as shown in FIG. 8, the concave surface 28 extends in the axial direction of the bolt 16 (vertical direction in FIG. 8).

  FIG. 8 shows a state in which the slider 11 is lowered to the lowest point with respect to the protrusion 9 of the pedestal main body 8 by its own weight. Under this condition, the position of the joint 6 is adjusted to the proper position through the relative movement of the slider 11 with respect to the projection 9 of the pedestal main body 8 and the slider bolt 11 is tightened at that position. Fixed against Thereafter, 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 adjusted after installation of the partition plate 3, 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 16 b of the head 16 a of the bolt 16, and in this state, the bolt 16 is rotated using the hexagonal wrench 31. When the hexagonal wrench 31 is inserted into the hexagonal hole 16 b to turn the bolt 16 in this manner, the guide portion 27 guides the position of the hexagonal hole 16 b in the bolt 16 as follows.

  That is, since the concave curved surface 28 of the guide portion 27 serves as a mark and the confirmation of the position of the hexagonal hole 16 b becomes easy by visual observation of the concave curved surface 28, the hexagonal wrench 31 can be easily inserted into the hexagonal hole 16 b. In addition, a hexagonal wrench 31 is inserted inside the concave surface 28, and in this state, the hexagonal wrench 31 is moved along the concave surface 28 and moved in the direction in which the concave surface 28 extends (axial direction of the bolt 16). 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 refers to a mark for facilitating the confirmation of the position of the bolt 16 (hexagonal hole 16b) by visual observation and the head 16a of the bolt 16 This means that the hexagonal wrench 31 can easily be made to face the operating position of the bolt 16 (the position of the hexagonal hole 16b) by the shape of the concave curved surface 28 located at the periphery. Even if it is necessary to insert 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 and guide it into the hexagonal hole 16b by guiding the position of the bolt 16 by the guide portion 27. The insertion can be facilitated, and the bolt 16 can be easily rotated using the hexagonal wrench 31.

  In addition, the guide about the position of the volt | bolt 16 by the guide part 27 may be only the display of the mark which makes it easy to confirm the position of the volt | bolt 16 (hexagonal hole 16b) by visual observation. In this case, for example, a portion on the bolt 16 side of the second end 6b of the joint 6 shown in FIG. 2 corresponding to the hexagonal hole 16b may be provided with a recess or the like using a punch or the like, and the recess may be a guide portion Be Furthermore, in order to make the above-mentioned recessed part stand out, you may make it put paint and an animal light paint in the recessed part. In addition, a portion on the bolt 16 side at the second end 6 b and corresponding to the hexagonal hole 16 b is marked with a paint or an animal light paint without providing a recess as described above, and that portion is the above guide portion It may function as

  8 and 9, further lengthen the bolt 16 so that the bolt 16 extends from the holding portion 12, thereby causing the head 16a of the bolt 16 to reach the concave surface 28 of the guide portion 27. You may do so. In this case, it is preferable that a cylindrical spacer be provided between the head 16 a of the bolt 16 and the second plate 19 of the fixing member 17 and that the threaded portion 16 c of the bolt 16 pass through the spacer.

  As described above, if the head portion 16 a of the bolt 16 has reached the concave surface 28 of the guide portion 27, the hexagonal wrench 31 is inserted into the concave surface 28 so that the head which is the operation position of the bolt 16. The hexagonal wrench 31 can be easily made to face 16a (hexagonal hole 16b). Further, by providing the spacer, the second plate 19 is pushed by the spacer when the head portion 16a of the bolt 16 is made to approach the holding portion 12 through the rotation operation. Therefore, even if the bolt 16 extends from the holding portion 12 so that the head portion 16 a of the bolt 16 reaches the concave curved surface 28 of the guide portion 27, the head 16 a of the bolt 16 approaches the holding portion 12 By doing this, the second plate 19 can be pressed.

  Note that instead of providing the spacer, the head 16a is provided with a projection that projects toward the second plate 19 to abut the second plate 19 or the second plate 19 protrudes toward the head 16a to meet the head 16a. You may provide a protrusion. By the way, if the above-mentioned spacer is provided, there is no need to provide those protrusions, so the head 16a and the second plate 19 do not have complicated shapes, and the head 16a of the bolt 16 with respect to the holding portion 12 The second plate 19 can be pressed by the approach.

  In FIGS. 8 and 9, the guide portion 27 and the concave surface 28 are extended toward the holding portion 12 to make the head 16a of the bolt 16 reach the concave surface 28 or the guide portion 27 and the concave surface 28 in the joint 6 are provided. The second end 6 b may be further provided at a position closer to the holding portion 12 to allow the head 16 a of the bolt 16 to reach the concave curved surface 28.
