Description

  The present invention relates to a pipe joint support structure in a sheath pipe header construction method.

  Conventionally, in the sheath pipe header construction method, pipe joints used when connecting resin flexible pipes that become sheath pipes under the floor and connecting to equipment on the floor are fixed to the washer installed on the floor of the cabinet. It is supported by a support member that is erected on a standing support bolt. This conventional support includes a storage body that stores the joint therein, and a fixing ring that fixes the joint stored in the storage body in a retaining state. The frame floor on which the support is installed is not so flat depending on the construction accuracy, and may be uneven. Therefore, this type of support is made by screwing the adjustment washer inserted through the support bolt and the flange provided on the outer periphery of the housing, and the adjustment nuts mounted on the top and bottom of the adjustment fitting are used as the support bolt. The height of the support can be adjusted by moving it up and down. Then, a flooring work for finishing material is then performed on the support whose height has been adjusted in this way, and a straight pipe to be piped on the finishing floor is connected.

  However, when using such a support, the height of the joint housing must be adjusted before the floor is pasted, and cannot be performed after the floor is pasted. If the installation is fixed, the support will protrude or retract on the finishing floor, and it will not be possible to install the decorative cover etc. well on the finishing floor. The troublesome work of adjusting the height and re-finishing the finishing floor was necessary.

  Therefore, recently, when the height adjustment of the support was necessary due to the unevenness of the floor of the chassis and the error during floor construction, it was intended to be able to adjust the height even after the floor was attached. For example, a support as described in Patent Document 1 has also been proposed.

As shown in FIG. 2, this type of support 8 has a male screw part 831 formed on the outer peripheral surface thereof on a support base 82 having a fixed washer 81, a support bolt 821 and an adjustment nut 822 fixed to the housing floor surface. A base 83 having an internal thread portion 832 formed on the inner peripheral surface, an adjustment sleeve 84 that is screwed into the internal thread portion 832 of the base 83 and moves up and down, and the pipe joint 85 is inserted inside; The fixing ring 86 is provided to fix the pipe joint 85 by screwing into the male screw portion 831 of the base 83. In the fixing method, the adjustment sleeve 84 is screwed about half of the base 83 and the pipe joint 85 is inserted into the adjustment sleeve 84. Next, the base 83 and a flexible pipe piped under the floor are connected and fixed using a stopper 87 and a screw 88 provided with locking claws, and the floor board is stuck in this state.
Japanese Patent No. 2609972

  However, even if the support tool 8 as described above is used, if the height adjustment is to be performed after the floor is attached, the fixing ring 86 is removed, the pipe joint 85 is removed, and the adjustment sleeve 84 is rotated to increase the height. It was necessary to make adjustments, and the number of parts was large with only the screwed members, and the adjustment work was troublesome. Further, at this time, when the support tool is retracted from the finishing floor, the adjustment sleeve 84 is under the floor, so that the adjustment work is very difficult. In addition, the support 8 has a configuration in which screw portions must be formed on both the inner and outer peripheral surfaces of the base 83, can be manufactured more easily and at low cost, and can be easily adjusted in height. A support structure for a pipe joint has been demanded.

  Therefore, the present invention has been made in view of the above problems, and the number of parts required to support a flexible pipe joint in the sheath pipe header method is reduced, thereby improving the efficiency of piping work. The present invention provides a pipe joint support structure that realizes a reduction in manufacturing cost with a simple structure and can easily adjust the position even if the connection height with the finished floor board is deviated.

  In order to achieve the above-described object, according to the present invention, a cylindrical support box is installed at a predetermined height position between the chassis floor and the finishing floor, and a pipe joint is fitted into and supported by the support box. In addition, a pipe joint support structure in which a fixed cover is externally fitted to a support box fitted with the pipe joint to prevent the pipe joint from being removed, and a male thread portion is formed on the outer peripheral surface of the pipe joint. A support ring that is screwed and locked to the upper end of the support box is provided, and this support ring is screwed into an appropriate position of the male thread portion of the pipe joint, so that the pipe joint is supported and fixed at a desired height position. It is characterized by that.

  According to this configuration, the pipe joint is supported by placing the support ring provided on the outer peripheral surface of the pipe joint on the upper end portion of the support box, so that the support height of the pipe joint depends on the screwing position of the support ring. Can be moved up and down. In this way, to adjust the height position of the pipe joint to the desired height, it is only necessary to pull up the pipe joint and rotate the support ring a little to change the screwing position, even after flooring. Height adjustment can be performed. Further, by adopting such a structure, it is not necessary to form a female screw part as in the conventional support tool inside the support box, and the structure becomes simple and the manufacturing cost can be reduced.

  Further, the inner peripheral surface of the support box is provided with a locking portion that can lock the support ring screwed into the male thread portion of the pipe joint, and the support ring is fitted inside the support box, The support ring on the outer peripheral surface of the pipe joint can be stored in the support box well, and the pipe joint can be held stably while preventing rattling.

  According to the pipe joint support structure of the present invention configured as described above, the number of parts required to support the joint can be reduced, so that the efficiency of the piping work can be increased and the pipe joint support is supported. Even if the height and the connection height with the finished floor board are shifted, it is possible to easily adjust the height and cope with it. Further, since each component member can also have a simpler structure than a conventional support tool, the manufacturing cost can be reduced.

  Hereinafter, the best mode for carrying out a pipe joint support structure according to the present invention will be described with reference to the drawings.

  FIG. 1 is a partial sectional view showing a pipe joint support structure of the present invention. The pipe joint support structure of the present invention is implemented between a housing floor surface (not shown) and the finishing floor 4. An opening 41 through which one end of the sheath pipe is movably inserted is formed in the finishing floor 4, and the cylindrical support box 2 is located at a predetermined height position from the housing floor surface immediately below the opening 41 of the finishing floor 4. is set up.

  The support box 2 has a cylindrical shape on the inner peripheral surface, and a male screw portion 24 is formed on the outer peripheral surface. The lower portion of the support box 2 is provided with fixing plate portions 21 projecting in a bowl shape on both the left and right sides, and insertion holes through which support bolts (not shown) standing on the floor of the housing can be inserted at both ends thereof. 22 is formed. A pipe joint 1 is fitted inside the support box 2, and a fixed cover 3 having a female screw part 31 on the inner peripheral surface is formed on the outer male screw part 24 of the support box 2 fitted with the pipe joint 1. It is the structure which is screwed and the pipe joint 1 is prevented from coming off.

  In such a pipe joint support structure, a male thread portion 12 is formed on the outer peripheral surface of the pipe joint 1. The male thread portion 12 is formed in a range of about 30 mm in length in the axial direction along the outer peripheral surface below the flange portion 11 provided on the upper portion of the pipe joint 1. The formation range of the male screw portion 12 is appropriately determined according to the height of the support box 2, and is preferably formed in a length range that is approximately ½ of the height of the support box 2.

  The male threaded portion 12 of the pipe joint 1 is provided with an annular support ring 13 having a circular outer shape. The support ring 13 has a female thread (not shown) formed on the inner peripheral surface thereof, and is screwed into the male thread portion 12 of the pipe joint 1. The support ring 13 screwed into the male thread portion 12 is integrated with the pipe joint 1. When the pipe joint 1 is fitted inside the support box 2, the support ring 13 is placed on the upper end portion of the support box 2. The pipe joint 1 is supported by locking. At this time, the height at which the pipe joint 1 is supported varies depending on the height position at which the support ring 13 is screwed into the male threaded portion 12 of the pipe joint 1. The pipe joint 1 can be supported and fixed at a desired height position by being moved up and down and screwed into an appropriate height position.

  Further, in the illustrated embodiment, a locking portion 23 that can lock the support ring 13 screwed into the male threaded portion 12 of the pipe joint 1 is provided on the inner peripheral surface of the support box 2 so as to protrude in the axial direction. As a result, a recess capable of accommodating the support ring 13 on the inner side is formed at the upper end of the support box 2 so that the support ring 13 can be fitted inside.

  Here, the support ring 13 may have a circular outer shape as described above, but may be formed in a polygon such as a hexagon or an octagon. And the internal shape of the latching | locking part 23 corresponding to this is formed in the same polygon, Therefore When it mutually fits, it can fix, it can comprise so that rotation may be prevented and a rotation may be prevented. . In addition, since the male screw portion 12 and the screw portion of the support ring 13 are both formed in the reverse screw direction, it is opposite to the screwing direction of the fixed cover 3, so that the members for use during construction and height adjustment are provided. The rotation can be prevented.

  As described above, in the pipe joint support structure according to the present invention, the pipe joint 1 is supported by being directly fitted into the support box 2 and supported by the support ring 13 screwed into the pipe joint 1. The height can be easily adjusted by moving the height up and down. Therefore, whenever the height adjustment becomes necessary regardless of before and after flooring, the pipe fitting 1 fitted in the support box 2 is pulled up and is directly screwed into the outer peripheral surface. The height can be easily adjusted simply by turning the screw to move the screwing position. If the pipe joint 1 whose screwing position of the support ring 13 has been adjusted is returned to the support box 2, the position of the pipe joint 1 can be set to a desired value. Can be height. In addition, since the locking portion is provided on the inner peripheral surface of the support box, the support ring is fitted inside the support box so that the pipe joint and the support ring can be accommodated in a well-contained manner.
