Abstract

A pipe support fitting for facilitating a height adjustment operation of a lower grip plate is provided.
A pipe support fitting for adjusting the height of a pipe P by fastening with nuts 16 and 17 in a state where the pipe P is interposed between upper and lower gripping plates 12 and 13. The insertion holes 14 and 15 of both the screw shafts 11 of the upper and lower gripping plates 12 and 13 are elongated holes, and the screw shaft is provided so as to be rotatable around the axis with respect to the base 10. When the screw shaft 11 is turned from the upper surface by a driver, the lower nut 16 that is prevented from rotating 18 by the lower gripping plate 12 moves in the axial direction of the screw shaft 11. At this time, since both the grip plates 12 and 13 can be largely tilted with respect to the screw shaft 11 through the long holes 14 and 15, the nut 16 can move within the tiltable range. For this reason, the width of the height adjustment of the lower holding plate 12 by one rotation of the screw shaft 11 is large and the adjustment is easy, and the pipe P can be easily supported and fixed at a predetermined height.

Description

  This device relates to a pipe support fitting for supporting and fixing a pipe such as a water pipe at a required height.

  For example, the water pipe is installed on a fixed object such as foundation concrete, a floor, or a wall with its support fitting. At this time, in order to secure the flow of water, the water distribution pipe is inclined in the length direction. A description will be given of a metal fitting to be supported with a gradient with reference to FIG. 1 showing an embodiment of the present invention. Vertical screw shafts 11 and 11 are provided on a pedestal 10 side by side. Elongated grip plates 12 and 13 are provided above and below, and both grip plates 12 and 13 are configured to be inserted into both screw shafts 11 and 11 through insertion holes 14 and 15 at both ends thereof. Yes (see Patent Document 1, Abstract, FIG. 1).

In this pipe support fitting, the nuts 16 and 17 screwed into the screw shaft 11 from above and below the upper and lower grip plates 12 and 13 are screwed in, so that the pipe P is interposed between the both grip plates 12 and 13. The pipes 12 and 13 are fastened to support the pipe P.
At this time, according to the thickness (diameter) and supporting height of the pipe P, the lower nut 16 is screwed to adjust the height of the lower holding plate 12 with respect to the screw shaft 11 to adjust the height of the pipe P. (See Patent Document 1, paragraphs 0003 to 0004).

  When adjusting the height of the lower gripping plate 12, the lower nut 16 is screwed up and down to move up and down. The nut 16 is positioned below the lower gripping plate 12 and attached to a mounting surface such as a floor surface. Since it is often located near the wall surface, it is difficult to turn it by hand. For this reason, the screw shaft 11 is rotatably provided around the shaft 10 with respect to the pedestal 10, and the lower nut 16 is rotated around the lower nut 16 by rotating the screw shaft 11 in a state where the lower nut 16 is prevented from being rotated. There is a technique for moving the plate 12 up and down with respect to the screw shaft 11 (see Patent Document 1, paragraphs 0021 to 0029 and FIGS. 1 to 7).

JP 2001-12654 A

  The prior art that can rotate the screw shaft 11 does not require the lower nut 16 to be rotated, so that the workability of the height adjustment of the holding plate 12 is improved. The insertion hole is a round hole (see FIG. 4 of Patent Document 1), and the lower grip plate 12 cannot be greatly inclined with respect to the screw shaft 11. For example, the degree of inclination of the lower gripping plate 12 is limited to the vertical movement caused by the rotation of the lower nut 16 by several screw threads, and the lower gripping plate 12 cannot be largely moved up and down with respect to the screw shaft 11.

  For this reason, one nut (for example, right side) 16 is rotated by several screw threads to move one end of the lower gripping plate 12, and then the other (for example, left side) nut 16 is rotated by several threads. The other end of the lower gripping plate 12 is alternately moved little by little by repeatedly moving the other end, and further rotating the one nut 16 by several screw threads to move the same end. The holding plate 12 is moved to a required height. This height adjustment work is complicated.

  This invention makes it a subject to make the height adjustment work of a lower side grip board smooth under the above actual condition.

In order to achieve the above object, according to the present invention, the insertion holes of both screw shafts of the lower holding plate are elongated holes in the longitudinal direction.
Thus, if the insertion hole of both screw shafts of the lower gripping plate is a long hole, the gripping plate can be tilted with respect to the screw shaft by movement within the long hole of the screw shaft. For this reason, the lower nut can be moved onto the screw shaft as long as the grip plate can be inclined.

  As a configuration of this device, a vertical screw shaft is provided on the pedestal side by side and a long grip plate is provided above and below the screw shaft, and both grip plates are inserted through insertion holes at both ends. The upper and lower gripping plates are fastened with the pipes interposed between the two gripping plates by screwing nuts screwed into the screw shafts from above and below the upper and lower gripping plates. In the pipe support fitting for adjusting the height of the upper and lower gripping plates, the insertion holes of the screw shafts of at least the lower gripping plate are elongated holes in the longitudinal direction of the gripping plate, and the screw shafts May be configured to be rotatable about its axis with respect to the pedestal so that it can rotate at its upper end.

  If comprised in this way, since a lower side grip plate can be largely inclined with respect to a screw axis | shaft by the movement in the long hole of a screw axis | shaft, turning the screw axis | shaft at the upper end (rotating) will prevent rotation. The lower nut thus made can move greatly in the axial direction of the screw shaft within a limit in which the lower gripping plate can be inclined. For this reason, it is not necessary to rotate the left and right screw shafts alternately and gradually move the lower grip plate up and down to adjust to the required height, but rotate one screw shaft to one end of the lower grip plate. After the desired height is reached, the other screw shaft can be turned to bring the other end of the lower gripping plate to the required height.

The length of the long hole is appropriately set so as to ensure an inclined state in the range of height adjustment of the lower holding plate in normal work.
The lower nut can be locked by hand or supported by a spanner, but the lower nut can be provided with a lower nut rotation stopper.
There are various modes of rotation at the upper end of the screw shaft. For example, a minus (−)-shaped groove, a plus (+)-shaped groove, a square hole, a hexagonal hole, or the like is formed on the top surface of the screw shaft. Alternatively, a square protrusion, a hexagonal protrusion, or the like may be formed, and a tip of a tool such as an electric screwdriver may be fitted in the groove or the like.

  In addition, if the insertion hole of the screw shaft of the upper gripping plate is a similar long hole, a large tilted state of the upper gripping plate can be secured as well as the lower gripping plate, and the upper and lower gripping plates can be piped in a tilted state. Can be gripped (see FIG. 8). Further, as described below, even in a state where the pipe is gripped by the upper and lower gripping plates, the height of the pipe can be adjusted by largely tilting both gripping plates by turning the screw shaft (see FIG. 7).

  As described above, the present invention allows the lower gripping plate to be largely inclined with respect to the screw shaft with the screw shaft insertion hole as a long hole, so that the height of the lower gripping plate can be easily adjusted. The piping can be easily adjusted to a predetermined height.

1 to 8 show an embodiment of a pipe support fitting according to the present invention. In this embodiment, as in the prior art, vertical screw shafts 11 and 11 are provided side by side on a pedestal 10 and both screws are provided. Long grip plates 12 and 13 are provided above and below the shafts 11 and 11 (see FIG. 1).
Insertion holes 14 and 15 of the screw shaft 11 are formed at both ends of the both gripping plates 12 and 13, and the insertion holes 14 and 15 are in the longitudinal direction of the gripping plates 12 and 13 (left and right in FIG. 5). (See FIGS. 4 and 5). The length T in the longitudinal direction of the long holes 14 and 15 may be appropriately determined based on experiments and actual work in consideration of the inclination of the grip plates 12 and 13 described below. For example, the length T Is preferably about 1/10 of the length L of the gripping plates 12 and 13. In this embodiment, L: 150 mm, T: 15 mm, and t: 10 mm, the diameter of the screw shaft 11 is about 9.5 mm (W3 / 8), and the grip plates 12 and 13 by the rotation of the screw shaft 11 are used. The inclination angle from the orthogonal state (horizontal state) to the vertical direction with respect to the screw shaft 11 is 30 degrees or more. From this, it is preferable that the major axis T of the insertion holes 14 and 15 is about 1.5 times the minor axis t.

  Both screw shafts 11 and 11 are provided such that their lower ends are inserted into the pedestal 10 and the protruding ends thereof are swaged and clamped 11a so that they can rotate (rotate) around the shaft with respect to the pedestal 10 (see FIG. 2). In addition, a cross-shaped (plus) groove 11b is formed on the top surfaces of the screw shafts 11 and 11 (see FIGS. 1 and 3), and the tip of a tool D such as an electric screwdriver is fitted into the groove 11b. Thus, the screw shaft 11 can be rotated.

The lower holding plate 12 is provided with protrusions 18 formed by cutting and raising at the edges of the insertion holes 14 at both ends thereof, and the nuts 16 are locked to the protrusions 18 to prevent the rotation (FIG. 1). FIG. 6 and FIG. 7).
One insertion hole 15 of the upper gripping plate 13 is formed with a notch 19 that opens to the outer edge, and the screw shaft 11 can be inserted into and removed from the insertion hole 15 through the notch 19 (FIG. 1, FIG. 1). (See FIG. 6). For this reason, as shown by a chain line in FIG. 1, the upper gripping plate 13 can be retracted from the one screw shaft 11 through the notch 19 and the pipe P can be placed on the lower gripping plate 12.

This embodiment has the above-described configuration. Next, one height adjustment operation of the pipe P according to this embodiment will be described with reference to FIG.
First, the pedestal 10 of this pipe support fitting is fixedly attached to a required mounting surface by a nail or a screw through a long hole 10a. At this time, inking is performed by the center mark of the central hole 10b. Moreover, the position of the base 10 with respect to the piping P can be adjusted by being the long hole 10a.

Next, the pipe P is placed on the lower gripping plate 12 in a state where the upper gripping plate 13 shown in FIG. 1 is retracted (see FIG. 6A). If the pipe P is already installed, the pedestal 10 is positioned below the pipe P so that the lower gripping plate 12 passes through the lower surface of the pipe P, and the pipe support bracket is attached by the screws or the like. Fix it to the surface. In this case, the pipe P does not necessarily have to be placed on the lower holding plate 12.
In this mounted state, for example, as shown in FIG. 6B, when one screw shaft 11, for example, the left screw shaft 11, is rotated by the electric driver D through the groove 11b on the top surface, the lower nut Since 16 is fixed with respect to the lower gripping plate 12 with a detent 18, the lower gripping plate 12 moves up and down with respect to the screw shaft 11. By rotating the screw shaft 11, one (left) end of the lower gripping plate 12 is positioned at a required height. At this time, the inclined state of the lower gripping plate 12 is allowed by the movement of the screw shaft 11 within the long hole insertion hole 14.

Subsequently, as shown in FIG. 6C, similarly, the other (right side) screw shaft 11 is turned to position the other end of the lower gripping plate 12 at a required height. At this time, if the pipe P is not positioned at the required height, the same rotation operation is appropriately performed on the left and right screw shafts 11 and 11 to adjust the height of both ends of the lower gripping plate 12. The pipe P is positioned at a required height. At these times, the upper nut 17 is raised (loosened) to a position where the lower nut 16 (one end of the lower gripping plate 12) is not hindered.

Even if one end (left end) of the lower gripping plate 12 is not positioned at a required height at a time, both ends (left and right ends) are alternately moved up and down to bring the pipe P to the required height. It can also be located. At this time, as compared with the prior art, the gripping plate 12 can be tilted greatly and the degree of vertical movement thereof can be increased, so that the workability is high.
When the screw shaft 11 is rotated, if the upper nut 17 is held by hand, the upper nut 17 moves up and down without rotating together with the rotation of the screw shaft 11, and the upper and lower nuts 16, 17 are moved. There is no change in the interval. For this reason, the upper nut 17 does not get in the way of the rise of the lower gripping plate 12.

  When the height adjustment of the lower gripping plate 12 is finished, the upper gripping plate 13 is rotated and one end thereof is notched through the notch 19 as shown by the solid line from FIG. 6 (d) and FIG. 11 to fit. Thereafter, the upper nut 17 is screwed and fixed to the upper surface of the upper gripping plate 13 by pressing, and the pipe P is gripped and fastened by the upper and lower gripping plates 12 and 13 to be supported and fixed. Thereby, the height adjustment of the pipe P by the pipe support fitting is completed.

  The other height adjustment work of the pipe P in this embodiment is as shown in FIG. 7, and after fixing the base 10 to the mounting surface, the pipe P is placed on the lower gripping plate 12, as described above. In a state where the upper gripping plate 13 is disposed on the upper side of the pipe P, the upper nut 17 is sufficiently loosened and positioned. For example, it is positioned about 10 mm above the upper gripping plate 13 (see FIG. 7A).

In this state, as shown in FIG. 7B, for example, as shown in FIG. 7B, the left screw shaft 11 is rotated to move one end of the lower gripping plate 12 up and down, and then FIG. ), The right screw shaft 11 is rotated to move the other end of the lower gripping plate 12 up and down. As the lower gripping plate 12 moves up and down, the pipe P and the upper gripping plate 13 are moved up and down to bring the piping P to a required height. At this time, since the insertion holes 15 of the screw shafts 11 of the upper gripping plate 13 are also long holes, the upper gripping plate 13 can follow the lower gripping plate 12 and be similarly inclined greatly (FIG. 7B). reference).
When the upper nut 17 is held by hand, the upper nut 17 does not interfere with the rise of the lower grip plate 12 and the upper grip plate 13 as described above.
Thereafter, the upper nut 17 is screwed and pressed against the upper gripping plate 13, and the pipe P is fastened and supported and fixed by the upper and lower gripping plates 12 and 13 via the nuts 16 and 17 (see FIG. 7D).

In this embodiment, since the insertion holes 14 and 15 of the screw shafts 11 of the upper and lower gripping plates 12 and 13 are long holes, the piping P is supported even when the gripping plates 12 and 13 shown in FIG. Can be fixed. That is, within the movable range of the screw shaft 11 in the insertion holes 14 and 15, the upper and lower grip plates 12 and 13 support the pipe P in an inclined state (a state inclined with respect to the screw shaft 11) including a horizontal state. obtain.
Incidentally, in this embodiment, when the nominal diameter of the pipe P is 40 to 80 mm, the pipe P can be supported and fixed with sufficient strength even when the upper and lower grip plates 12 and 13 are inclined as well as horizontal. It was.
In addition, each insertion hole 15 of the both screw shafts 11 of the upper gripping plate 13 may not be a long hole but may be a circular hole (buck hole) through which the screw shaft 11 can move.
