Description

  The present invention relates to an electrical insulating plate used when a pipe is attached to a bracket, a pedestal, or a steady rest, and a pipe fixture using the same.

  In air conditioning equipment construction and sanitary equipment construction, various pipes are used according to applications and purposes, and are roughly divided into metal pipes and resin pipes when classified by material.

  Here, the metal pipe includes a carbon steel pipe for piping called a gas pipe, a carbon steel pipe for pressure piping called a schedule pipe, a stainless steel pipe for general piping, a lining steel pipe, and the like. For a wide range of applications such as drainage, ventilation, and fire extinguishing, carbon steel pipes for pressure piping are used for cold / warm water, cooling water, high-pressure steam, etc. whose working pressure exceeds 0.98 MPa, and stainless steel pipes for general piping are lined for air conditioning and sanitary equipment. Steel pipes whose inner surfaces are coated with polyethylene or hard polyvinyl chloride are used as water supply pipes.

  When installing these pipes in the building, if they are horizontal running pipes, they can be suspended from the ceiling or upper floor slab with a suspension band, or they can be mounted on brackets attached to the wall surface or on a gate-type frame installed on the floor. After being placed, it is fixed to these brackets and mounts with U-bolts, and if it is a riser tube, it is fixed to the wall with a stand-up band and fixed to a steady rest attached to the wall surface with U-bolts.

  On the other hand, when the pipe is a metal pipe, it is necessary to consider corrosion prevention of the pipe by electrically insulating the metal U bolt, bracket, gantry, or steady rest. In addition to covering with an electrical insulating material, measures are taken to sandwich a plate made of an electrical insulating material between the pipe and the bracket, gantry or steady rest.

JP-A-10-213118

  For example, in the case of the invention described in Patent Document 1, the attached object 10, which is a pipe, has the male screw portions 3, 3 of the U bolt 1 (bolt body 2) arranged so as to straddle the attached object. After passing through the insertion hole 14a, the male screw portion is further inserted into a bolt hole 11a formed in the support body 11 such as a structure, and is fastened with a nut 6 via a spring washer 15, thereby being fixed to the support body 11. The pedestal 14 is formed of a plate made of a synthetic resin material having electrical insulation (see paragraphs [0019] to [0020] of Patent Document 1).

  According to the invention described in Patent Document 1, in combination with the configuration in which the insulating tube 4 made of an electrically insulating material is externally attached to the curved portion 2A of the bolt body 2, the attachment object 10 as a pipe and the metal The U-bolt 1 and the support 11 which is a pedestal are electrically insulated, thus preventing contact corrosion of dissimilar metals.

  Here, in the case of using the electrical insulating plate represented by the pedestal 14 described in Patent Document 1, when inserting the male screw of the U bolt into the bolt hole of the electrical insulating plate, the U bolt is in a state of straddling the pipe in advance. It must be.

  Therefore, when fixing the transverse pipe to a bracket or a base (hereinafter referred to as a bracket or the like), first, the electric insulation plate is arranged so that the bolt hole of the electric insulation plate is aligned with the bolt hole of the bracket or the like. Is placed on a mounting surface such as a bracket, and then a horizontal running tube is placed on the electrical insulating plate, and then a U bolt is placed on the bracket or the like so as to straddle the horizontal running tube. The male screw is inserted into a bolt hole such as an electrical insulating plate and a bracket, and is tightened with a nut.

  However, the electrical insulation plate may be displaced when placing the transverse tube, and in that case, the position of the electrical insulation plate must be adjusted again so that the above bolt holes are aligned. In the meantime, the side running tube had to be lifted from the bracket or the like, and there was a problem that it took time to fix the bracket to the bracket or the like.

  In addition, when fixing the riser to the steady rest, the U-bolt must be inserted while holding the electrical insulating plate in the above-mentioned position, and the U-bolt is not applied to the pipe, although it does not act on the pipe. However, depending on the situation, for example, when working at a high place, there is a problem that it may be difficult to align and maintain the state.

  The present invention has been made in consideration of the above-described circumstances, and can be easily fixed to a bracket or the like with a U-bolt while being sandwiched between the pipe and a bracket or the like or a steady state. An object of the present invention is to provide an insulating plate and a pipe fixture using the same.

To achieve the above object, according to the first aspect of the electrical insulating plate of the present invention, two plate-side bolt holes are formed apart from each other, and a pipe abuts between the two plate-side bolt holes. The two plate-side bolt holes can be inserted through the two plate-side bolt holes together with the two support-unit-side bolt holes provided in the support means to which the pipe is fixed. In the electrical insulating plate configured to be able to electrically insulate the support means and the pipe,
In-plane with respect to the support means is provided by projecting locking means that are locked to the opening peripheral edges of the two support means-side bolt holes from the opening peripheral edges of the two plate-side bolt holes toward the out-of-plane direction. The configuration is such that the direction movement is restricted.

  In the electrical insulating plate according to the present invention, the locking means is an annular protrusion formed in an annular shape along the periphery of the opening of the plate-side bolt hole.

  In addition, the electrical insulating plate according to the present invention includes a pair of receiving seats that are spaced apart from each other on the projecting side of the locking means and the back-to-back side of the locking means. The seats are configured such that their tips abut against the outer peripheral surface of the pipe.

  In addition, the electrical insulating plate according to the present invention has a double-sided tape attached between the two plate-side bolt holes and on the projecting side of the locking means.

Further, as described in claim 5, the pipe fixture according to the present invention is arranged so as to straddle the pipe and is configured to fix the pipe to the support means, and the peripheral surface is covered with an electrical insulating material. A U-bolt and an electric insulating plate configured to be electrically insulated by being sandwiched between the support means and the pipe, and two plate-side bolt holes are formed in the electric insulating plate apart from each other In addition, a contact surface is provided between the two plate-side bolt holes so that the pipe is in contact with the two plate-side bolt holes, together with the two support means-side bolt holes provided in the support means. In the pipe fixture configured so that the two male screws of the U bolt can be inserted respectively.
In-plane with respect to the support means is provided by projecting locking means that are locked to the opening peripheral edges of the two support means-side bolt holes from the opening peripheral edges of the two plate-side bolt holes toward the out-of-plane direction. The configuration is such that the direction movement is restricted.

  Further, the pipe fixture according to the present invention is characterized in that the pipe is a horizontal pipe, the support means is a bracket attached to a wall surface or a pedestal installed on a floor surface, or the pipe is a rising pipe, and the support means is a wall surface. It is a steady rest attached to.

  In the electrical insulating plate according to the present invention, a pair of plate-side bolt holes for inserting two male screws provided in the U-bolt are spaced apart from each other as in the prior art. Locking means project from the peripheral edge of the opening of the two plate-side bolt holes toward the out-of-plane direction, and the locking means is locked to the peripheral edge of the opening of the two support means-side bolt holes, In-plane direction movement with respect to the support means is restricted.

  Further, in the pipe fixture according to the present invention, a pair of plate side bolt holes for inserting two male screws provided in the U bolt are formed apart from the electric insulating plate as in the conventional case. In the present invention, locking means are projected from the peripheral edge of the opening of the two plate side bolt holes toward the out-of-plane direction, and the locking means includes two support means side bolts provided on the support means. By being locked to the opening periphery of the hole, the in-plane movement of the electrical insulating plate relative to the support means is restricted.

  In this case, when the electrical insulating plate of the present invention is arranged on the bracket, the pedestal or the steady rest as the support means, the electrical insulation plate locking means is locked to the opening periphery of the support means side bolt hole. By disposing the electrical insulating plate on the support means, it is possible to easily align the plate-side bolt hole and the support means-side bolt hole, and to support the pipe so that the electrical insulating plate is sandwiched therebetween. Also when it arrange | positions, the state by which the plate side bolt hole was aligned with the support means side bolt hole is hold | maintained.

  That is, when the pipe is a laterally-running pipe, it passes through the laterally-running pipe. Even if such a situation occurs, the plate-side bolt hole shifts from the support-unit-side bolt hole as the electric insulating plate slides on the installation surface of the support means. Thus, the workability when fixing the pipe with the U bolt is significantly improved.

  The plate side bolt hole and the support means side bolt hole are included even when they are round holes, but a configuration as a long hole is a typical example.

  The locking means is provided so as to project from the opening peripheral edge of the two plate-side bolt holes toward the out-of-plane direction, but is supported by being locked to the opening peripheral edge of the two supporting means-side bolt holes As long as the in-plane movement of the electrical insulating plate relative to the means is limited, the specific configuration is arbitrary.

  For example, among the opening peripheral edges of the two supporting means side bolt holes, the opening peripheral edges of the two plate side bolt holes are also centered on the bolt hole centers so as to be respectively locked to the opening peripheral edges near the bolt hole center. Two plate-side bolts that are formed in a semi-annular shape at the opening periphery on the near side, and that are respectively locked to the opening periphery on the side far from the center of the bolt hole, of the opening periphery of the two support means side bolt holes Of the opening periphery of the hole, the structure formed in a semi-annular shape on the opening periphery on the side far from the center of the bolt hole is included in the locking means of the present invention, but formed annularly along the opening periphery of the plate-side bolt hole In the configuration of the annular protrusion, the annular protrusion is fitted into the support means side bolt hole, so that the lateral displacement of the electric insulating plate with respect to the support means is more reliably prevented.

  The in-plane direction movement means a lateral displacement that prevents the two male screws provided on the U-bolt from being inserted into the two plate-side bolt holes and the two support means-side bolt holes. If there is no hindrance to the insertion of the two male screws described above, some in-plane phrase movement such as play and rattling is naturally allowed.

  As long as they are electrically insulated by being sandwiched between the piping and the support means, the electrical insulation plate is optional in what material and how it is constructed, and the whole is non-conductive such as plastic The structure formed of the material and the structure in which the surface of the metal base material is coated with the non-conductive material are at least included, and how to perform electrical insulation between the pipe and the U bolt is related to the present invention. It is optional for the electrical insulating plate.

  In addition, in the piping fixture which concerns on this invention premised on combined use with a U volt | bolt, it becomes the structure using the U volt | bolt by which the surrounding surface was coat | covered with the electrical insulating material.

  In the pipe fixing device according to the present invention, the pipe is a horizontal pipe, the support means is a bracket attached to the wall surface or a pedestal installed on the floor surface, or the pipe is a rising pipe and the support means is attached to the wall surface. A typical configuration is a stopped configuration.

  The contact surface of the electric insulation plate is the contact surface with the pipe when the pipe is placed on the electric insulation plate when the pipe is a horizontal running pipe, and the pipe is a rising pipe Means a contact surface with the pipe when the pipe is pressed against the electric insulating plate from the side.

  Here, a pair of receiving seats are provided on the contact surface of the electric insulating plate, which is the back-to-back side of the locking means and spaced apart from each other. If configured to abut the outer peripheral surface of the pipe, stabilize the pipe when placing the transverse pipe on the electrical insulation plate or pressing the riser from the side against the electrical insulation plate. Therefore, the fixing work to the supporting means by the U bolt is further facilitated.

  The pair of seats need not be in contact with the outer peripheral surface of the pipe at the same time when the pipe is in contact with the contact surface. It is sufficient that the front end of the seat abuts on the outer peripheral surface of the pipe.

  When the electric insulating plate is arranged on the supporting means, the above-described locking action is used, and if it is a laterally-running tube, the electric insulating plate may be simply placed on a bracket or a pedestal that is the supporting means, or a riser pipe. For example, the electric insulating plate may be simply pressed against the steady rest that is the support means, but if a double-sided tape is adhered between the two plate-side bolt holes and on the protruding side of the locking means, Since the electrical insulating plate is bonded to the supporting means via the double-sided tape, the above-described lateral displacement of the electrical insulating plate can be more reliably prevented. At this time, it is not necessary to hold the electric insulating plate with a finger, and the workability at a high place is greatly improved.

  Embodiments of an electrical insulating plate and a pipe fixture using the same according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is an overall perspective view showing an electrical insulating plate and a pipe fixture according to the present embodiment. As can be seen from these drawings, the pipe fixture 1 according to the present embodiment is composed of a U bolt 2 and an electrical insulation plate 3, and the U bolt 2 has a circumferential surface covered with an electrical insulation material 4. is there.

  The electrical insulating plate 3 is formed with two plate side bolt holes 6 and 6 through which the two male screws 5 and 5 provided in the U bolt 2 are inserted, respectively. There is an abutting surface 8 between which the transverse pipe 7 which is a pipe abuts.

  The electrical insulating plate 3 is mounted on the bracket 11 so that the two plate-side bolt holes 6 and 6 are aligned with the two support means-side bolt holes 12 and 12 provided in the bracket 11 as the support means. In the state where the U bolt 2 is disposed so as to straddle the transverse tube 7 abutted on the abutting surface 8, the two male screws 5, 5 are connected to the two plate-side bolt holes 6, 6 and two The transverse tube 7 can be fixed to the bracket 11 by being inserted into the support means side bolt holes 12 and 12 and screwing the nuts 13 and 13 into the respective ends of the male screws.

  The bracket 11 is a support means attached to a wall surface (not shown) and is composed of angle steel (angle), and the transverse pipe 7 is called a carbon steel pipe for piping called a gas pipe and a schedule pipe. It consists of metal pipes such as carbon steel pipes for pressure piping, stainless steel pipes for general piping, and lining steel pipes, and the electric insulation plate 3 is made of synthetic resin so that these transverse pipes 7 and brackets 11 are electrically insulated. It is.

  The electric insulating plate 3 according to this embodiment has annular protrusions 21 and 21 as locking means that are locked to the peripheral edges of the two support means side bolt holes 12 and 12, as can be seen well in FIGS. By projecting from the opening peripheral edge of the two plate-side bolt holes 6 and 6 toward the out-of-plane direction, the in-plane movement of the bracket 11 with respect to the installation surface 14 is restricted.

  The annular protrusions 21 and 21 are formed in an annular shape along the opening peripheries of the two plate-side bolt holes 6 and 6, and the protruding height thereof is approximately the same as the thickness of the plate body constituting the electrical insulating plate 3, for example. Should be set.

  The plate side bolt holes 6 and 6 and the support means side bolt holes 12 and 12 are preferably formed as long holes in order to improve workability when the male screws 5 and 5 of the U bolt 2 are inserted.

  The annular protrusions 21 and 21 are appropriately determined in size and outer diameter if the plate-side bolt holes 6 and 6 are round holes so that the annular protrusions 21 and 21 are smoothly fitted into the support means-side bolt holes 12 and 12 of the bracket 11. .

  On the contact surface 8 of the electrical insulating plate 3, a pair of receiving seats 22, 22 are provided on the projecting side of the annular projections 21, 21 so as to be back-to-back with each other. The seats are configured such that their tips 23, 23 abut against the outer peripheral surface of the transverse tube 7.

  In order to fix the transverse pipe 7 to the bracket 11 using the pipe fixture 1 according to the present embodiment, first, as shown in FIG. The electrical insulating plate is placed on the installation surface 14 of the bracket 11 so as to be fitted into the support means side bolt holes 12, 12.

  In this way, the two plate side bolt holes 6, 6 of the electrical insulating plate 3 are provided in the bracket 11 by the locking action of the annular protrusions 21, 21 with respect to the opening peripheral edges of the two support means side bolt holes 12, 12. The two support means side bolt holes 12, 12 are automatically aligned.

  Next, as shown in FIG. 4 (b), the lateral tube 7 is bracketed via the electrical insulating plate 3 in such a manner that the outer peripheral surface of the lateral tube 7 is brought into contact with the contact surface 8 of the electrical insulating plate 3. 11 on top.

  At this time, even if the lateral running tube 7 tends to shift to either side, the distal end 23 of the receiving seat 22 located on that side abuts against the outer peripheral surface of the lateral running tube 7 and restrains the displacement operation of the lateral running tube. To do. That is, the pedestals 22 and 22 function as a stopper that restrains the displacement of the lateral running tube 7 and stabilizes the mounting state of the lateral running tube 7 on the bracket 11.

  Next, the U bolt 2 is dropped from the upper side of the bracket 11 so as to straddle the transverse tube 7, and the male screws 5, 5 of the U bolt are inserted into the plate side bolt holes 6, 6 and the support means side bolt holes 12, 12. Insert.

  At this time, since the plate side bolt holes 6 and 6 and the support means side bolt holes 12 and 12 are aligned in advance by the locking action of the annular protrusions 21 and 21 as described above, the U bolt 2 is moved from above. The male screws 5 and 5 of the U bolt are inserted into the plate side bolt holes 6 and 6 and the support means side bolt holes 12 and 12, respectively, simply by dropping them.

  Finally, nuts 13 and 13 are screwed into the respective ends of male screws 5 and 5, and these are tightened to fix transverse running tube 7 to bracket 11.

  As described above, according to the electrical insulating plate 3 and the pipe fixture 1 using the same according to the present embodiment, the support means side bolt holes 12 and 12 provided in the bracket 11 are locked to the opening peripheral edges. By projecting the annular protrusions 21 and 21 from the peripheral edges of the plate-side bolt holes 6 and 6 of the electrical insulating plate 3 toward the out-of-plane direction, the in-plane movement of the electrical insulating plate 3 relative to the bracket 11 is limited. If the electrical insulating plate 3 is arranged in the bracket 11 so that the annular protrusions 21 and 21 are fitted in the support means side bolt holes 12 and 12, the plate side bolt hole is locked by the engagement action. 6, 6 can be easily aligned with the support means side bolt holes 12, 12, and the transverse tube 7 is mounted on the bracket 11 through the electrical insulating plate. Even when a load in the in-plane direction (displacement direction) is applied to the electrical insulating plate 3 via the horizontal running tube 7 when placing, there is no possibility that the electrical insulating plate 3 is laterally displaced with respect to the installation surface 14 of the bracket 11. Thus, the workability at the time of fixing the transverse tube 7 by the U bolt 2 is remarkably improved.

  In addition, according to the electrical insulating plate 3 and the pipe fixture 1 using the electrical insulating plate 3 according to the present embodiment, the pair of receiving seats 22 and 22 protrude from the contact surface 8 of the electrical insulating plate 3 so as to be separated from each other. Since the pair of seats are configured such that their tips 23 and 23 come into contact with the outer peripheral surface of the lateral tube 7, the pedestals 22 and 22 function as stoppers for restraining the displacement of the lateral tube 7, and thus It becomes possible to stabilize the mounting state of the transverse tube 7 on the bracket 11.

  In the present embodiment, the pair of receiving seats 22 and 22 are provided so as to protrude from the contact surface 8 of the electrical insulating plate 3, but if there is no problem in the mounting stability of the lateral running tube 7, It can be omitted.

  Further, although not particularly mentioned in the present embodiment, as shown in FIG. 5, instead of the electrical insulating plate 3, the projections of the annular projections 21, 21 are provided between the two plate-side bolt holes 6, 6. An electrically insulating plate 3a formed by adhering a double-sided tape 51 to the side can be employed.

  According to this configuration, since the electrical insulating plate 3a is bonded to the bracket 11 as the support means via the double-sided tape 51, the above-described lateral displacement of the electrical insulating plate 3 can be more reliably prevented.

  Since the electrical insulating plate 3a has the same configuration as that of the electrical insulating plate 3 except for the configuration where the double-sided tape 51 is adhered, the detailed description thereof is omitted here. Further, as described above, the pair of seats 22 and 22 can be omitted.

  Further, in the present embodiment, the pipe is constituted by the transverse pipe 7 and the support means is constituted by the bracket 11. However, instead of the bracket, a stand installed on the floor may be used as the support means, or instead of these arrangements. As shown in FIG. 6, the pipe may be a rising pipe 61 and the support means may be a steady stop 62 attached to a wall surface (not shown).

  In such a configuration, the rising pipe 61 is made of a metal pipe in the same manner as the lateral running pipe 7, and the steady rest 62 is made of angle steel, and the electric insulating plate is particularly the electric insulating plate 3a. It consists of

  If comprised in this way, like the above-mentioned embodiment, this electrical insulation plate will be steady | strained 62 so that the cyclic | annular protrusions 21 and 21 of the electrical insulation plate 3a may be latched by the opening periphery of the support means side bolt hole 12 and 12. , The plate-side bolt holes 6 and 6 and the support means-side bolt holes 12 and 12 can be easily aligned, and the riser pipe 61 can be placed in such a manner that the electric insulating plate 3a is sandwiched therebetween. Even when it is arranged in the steady rest 2, the plate side bolt holes 6, 6 are kept aligned with the support means side bolt holes 12, 12.

  That is, even if a load in the in-plane direction (displacement direction) acts on the electrical insulating plate via the operator's finger pressing the electrical insulating plate 3a, the electrical insulating plate 3a There is no risk that the plate-side bolt holes 6 and 6 are displaced from the support means-side bolt holes 12 and 12 by moving in a sliding manner, and thus the workability when the rising pipe 61 is fixed by the U bolt 2 is remarkably improved. .

  Further, when the riser 61 is pressed against the electrical insulating plate 3b from the side, the riser can be stabilized by the action of preventing the pedestals 22 and 22 from being displaced, so that the fixing work to the steady rest 62 by the U bolt 2 is easy. become.

  Here, in this modification, the U-bolt 2 can be fixed in a state where the electrical insulating plate 3a is bonded to the steady rest 62 by the adhesive action of the double-sided tape 51. It is no longer necessary to hold the electrical insulating plate 3a with a finger so that the electrical insulating plate 3a does not fall, and the workability at a high place is particularly improved.

  In the present embodiment, the annular protrusions 21 and 21 constitute the locking means of the present invention, but the locking means are locked to the opening peripheral edges of the two support means side bolt holes 12 and 12. As long as the in-plane movement of the electrical insulating plate relative to the support means is limited, the specific configuration is arbitrary. For example, as shown in FIG. 7 (a), the two support means side bolt holes 12, 12 are provided. Of the opening rims of the two plate-side bolt holes 6, 6, half of the opening rims on the side that is also far from the bolt hole center so that they are respectively locked to the opening rims on the side far from the bolt hole center. The locking means of the present invention can be constituted by semi-annular protrusions 71, 71 formed in an annular shape, and as shown in FIG. 5 (b), the opening peripheral edges of the two support means side bolt holes 12, 12 Each of them is locked to the opening edge near the bolt hole center. As shown in the drawing, the locking means according to the present invention is formed by semi-annular protrusions 72 and 72 formed in a semi-annular shape on the opening peripheral edge of the two plate-side bolt holes 6 and 6 on the side close to the center of the bolt hole. May be configured.
