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, the pipe joint used when connecting the flexible resin pipe to be the sheath pipe under the floor and connecting to the equipment on the floor has been erected on the fixed washer on the floor of the frame. It is supported by a support member installed on the 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 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 applying the floor, and cannot be done after applying the floor. If this happens, the support tool 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 surface. The troublesome work of adjusting 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. 3, this type of support 8 has a male screw portion 831 formed on the outer peripheral surface thereof on a support base 82 having a fixed washer 81, a support bolt 821 and an adjusting nut 822 fixed to the frame floor. 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. Adjustment had to be made, and only the screwed members required time and labor for adjustment, and the number of parts was large. 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.

  Accordingly, the present invention has been made in view of the above-described problems, and can easily adjust the height by reducing the labor required when adjusting the support height of the joint of the flexible tube in the sheath header method. Pipe joints that reduce the number of parts required to support flexible pipe joints, increase the efficiency of piping work, and reduce the manufacturing cost with a simple structure. A support structure is provided.

  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. And a pipe joint support structure in which a fixed cover is externally fitted to the support box fitted with this pipe joint to prevent the pipe joint from being attached, and a support projection is provided on the outer peripheral surface of the pipe joint, On the inner peripheral surface, a plurality of engagement grooves having different depths that can be locked by the support protrusions of the pipe joint are formed. Of these, the support protrusions of the pipe joint are formed in the engagement grooves of an appropriate depth. The pipe joint is supported and fixed at a desired height position by engaging and fitting the pipe joint to the support box.

  According to this configuration, since the pipe joint is supported by the engagement protrusion formed in the engagement groove formed in the support box, the support height of the pipe joint can be changed depending on the depth of the engagement groove. it can. Thus, to adjust the height position of the pipe joint to the desired height, the pipe joint is pulled up even after the floor is stuck, and the support protrusion is locked in the lock groove of an appropriate depth of the support box. It is only necessary to re-install the pipe joint, and the height can be adjusted easily. 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, according to the present invention, in the pipe joint support structure having the above-described configuration, the support projections of the pipe joint are provided in two pieces symmetrically with respect to the pipe axis, and the engagement grooves of the support box are arranged radially in a top view. The pair of opposing engaging grooves are preferably formed at the same depth.

  By adopting such a configuration, the two support protrusions are respectively engaged with the pair of engagement grooves of the support box, and the pipe joint can be stably supported without being loosened.

  According to the pipe joint support structure of the present invention configured as described above, the labor for adjusting the support height of the pipe joint is reduced, and the height can be easily adjusted as necessary. The efficiency of piping work can be increased. In addition, since each component member in the pipe joint support structure of the present invention can 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 an exploded perspective view showing a pipe joint support structure of the present invention, and FIG. 2 is a partial cross-sectional view showing the pipe joint support structure of FIG.

  The pipe joint support structure according to the present invention is implemented between a housing floor surface (not shown) and the finishing floor 5. An opening 51 through which one end of the sheath pipe is movably inserted is formed in the finishing floor 5, and a cylindrical support box 2 is installed immediately below the opening 51 at a predetermined height position from the housing floor surface. .

The support box 2 has a male screw portion 21 formed on the outer peripheral surface. The lower portion of the support box 2 is provided with a fixing plate portion 22 extending in a bowl shape on both the left and right sides, and insertion holes 23 through which support bolts 821 erected on the housing floor surface can be inserted at both ends thereof. ing.

  A pipe joint 1 is fitted inside the support box 2. In the illustrated form, the pipe joint 1 is provided with two pieces of support protrusions 11 on the upper portion of the outer peripheral surface so as to project in a blade shape that is symmetrical with respect to the pipe axis of the pipe joint 1. On the inner peripheral surface of the support box 2, there is provided an engagement groove 24 that can lock and support the support protrusion 11 when the pipe joint 1 is inserted.

  In the illustrated embodiment, a plurality of engaging grooves 24 are formed on the upper inner peripheral surface of the support box 2 and are arranged radially in a top view. The pair of opposing engaging grooves 24 are formed as grooves having the same depth, and a total of six pairs of engaging grooves 24 having different depths are provided.

  Such engagement grooves 24 are formed so as to have different depths, for example, in units of 2 mm with respect to the adjacent engagement grooves 24, and are configured such that the depths become deeper (or shallower) in order in the circumferential direction. It is desirable.

  Of the engagement grooves 24 having different depths, the support protrusion 11 of the pipe joint 1 is locked in the engagement groove 24 having an appropriate depth, and the pipe joint 1 is fitted into the support box 2. . Since the height for supporting and fixing the pipe joint 1 varies depending on the depth of the engagement groove 24, the support protrusion 11 is locked to the engagement groove 24 which is preferable for adjusting the height by using this, and the pipe joint 1 is fixed. It is the structure which can adjust 1 support height.

  Further, the fixed cover 4 provided with the female thread portion 41 on the inner peripheral surface is screwed into the male thread portion 24 on the outer side of the support box 2 fitted with the pipe joint 1 in this manner, thereby preventing the pipe joint 1 from coming off. It is configured as follows.

  In the illustrated embodiment, the engagement grooves 24 of the support box 2 are not limited to the configuration in which the engagement grooves 24 having the same depth are provided at the opposing positions as described above, and all the engagement grooves 24 are formed at different depths. A configuration may be adopted in which only one support protrusion 11 is formed on the pipe joint 1 and is locked to any one of the engagement grooves 24 while being formed.

  The length of the support protrusion 11 of the pipe joint 1 is preferably formed so as to correspond to the depth of the deepest engagement groove 24. As a result, when the support protrusion 11 is locked in the deepest engagement groove 24, there is no gap between the upper portion of the engagement groove 24 and the fixed cover 4. .

  As described above, in the pipe joint support structure according to the present invention, when the pipe joint 1 is inserted into the upper inner peripheral surface of the support box 2 by the engagement groove 24 having the above-described configuration. The support protrusion 11 is supported by being engaged with the engagement groove 24 on the inner peripheral surface of the support box 2. Therefore, since the support height of the pipe joint 1 depends on the depth of the engagement groove 24, the support height of the pipe joint 1 and the finish floor 5 may vary depending on the unevenness of the frame floor surface or the construction error of the floor plate. When the connection height is deviated, the height can be easily adjusted by locking the support protrusion 11 of the pipe joint 1 in the engagement groove 24 corresponding to the height to be adjusted.

Further, since the operation is only to lock the support protrusion 11 of the pipe joint 1 in the appropriate engagement groove 24 of the support box 2, no complicated work is required, and the height is increased regardless of before and after floor bonding. When adjustment is necessary, the height can be adjusted at any time, and the workability can be greatly improved. Furthermore, since the support protrusion 11 is formed in a blade shape on the outer peripheral surface of the pipe joint 1, the pipe joint 1 is positioned and fixed when engaged with the pair of engagement grooves 24, and the lateral displacement Shaking can also be prevented. Further, with the above-described structure, it is not necessary to form a female screw portion as in a conventional support tool inside the support box, so that the structure is simple and the manufacturing cost can be reduced.

  The pipe joint support structure according to the present invention is suitable as a pipe joint support structure for attaching a faucet in the sheath pipe header method and connecting pipes under the floor so that the height can be easily adjusted even after finishing floor construction. Can be used to
