Description

  This application is a penetrating part forming member that penetrates the floor or wall when various wiring and piping materials are arranged under the floor or behind the wall in a sheath tube system, and the sheath pipe is connected to the inside of the sheath pipe. Wiring or piping material that is inserted through is used to connect to various equipment on the floor or on the wall surface, or to pull out wiring or piping material from the back of the wall to the wall surface, etc. The present invention relates to a penetrating part forming member and a device using the same.

  One method for piping hot water, gas, etc. under the floor or behind the wall is the so-called sheath tube system. This is a system in which flexible piping is inserted into the sheath tube. The end of this sheath tube is connected to a penetrating member that penetrates the floor or wall, and the opening of the penetrating member faces the floor or wall surface. In addition, a joint for connecting to various facilities on the floor or on the wall surface is attached to this opening, or an outlet forming tool for inserting wiring / piping is attached.

  For example, when a water pipe is inserted through a sheath pipe, there is a faucet as equipment to be connected to the joint. In other words, the water pipe piped on the back of the wall is connected to the joint on the wall surface through the penetrating part forming member penetrating the wall, and communicates with the faucet on the wall surface through this joint.

  In some cases, a water pipe or the like is drawn from the back of the wall to the wall surface as it is without using a joint. In this case, the outlet forming tool 30b as shown in FIG. 22 is used, and the penetrating part forming member is inserted through the wall of the flexible water pipe 2a through which the sheath pipe has been inserted. The water pipe 2a is pulled out to the wall surface as it is through the outlet port of the outlet forming tool 30b provided in the opening on the wall surface side.

  In the waterproof structure of the faucet mounting portion of Patent Document 1 shown here, as shown in FIG. 23, the fixing ring 30a is screwed to the box 100 ′ (corresponding to the penetration portion forming member of the present application). The wall W is fixed between the inside and outside of the wall W by the box 100 ′ and the fixing ring 30a (Patent Document 1).

For example, in the relay connector shown in Patent Document 2, as shown in FIG. 24, the flange-shaped fixing portion 34 formed on the joint 30a is directly fixed to the wall W with screws.

  According to the invention of Claims 12 and 13, it is possible to provide a joint and an outlet forming tool regardless of the wall thickness at the construction site.

  Next, an embodiment of the present invention will be described with reference to the drawings.

  The first embodiment relates to the inventions of claims 1, 3 to 5, 7, 11, and 12. 1 and 2 show a front view and a plan view of the penetrating part forming member 100, as shown in the cross-sectional view of FIG. 3, and a substantially cylindrical tubular part 10 and the tubular part. The one side member 20 (refer FIG. 4) of the substantially square flange shape provided in the base end side is provided. Moreover, this penetration part formation member 100 is a product made from a synthetic resin. Here, the one side is, for example, the back side of the wall, and therefore the base end side 10A of the cylindrical body portion 10 is the back side (one side) of the cylindrical body portion disposed in the through hole of the wall. The other side is the front side of the wall and is the same side as the distal end side 10 </ b> B of the cylindrical body part 10.

  The cylinder part 10 is arrange | positioned at the through-hole of a wall, and has the same length as the largest wall thickness of the assumed wall. Therefore, in the wall thinner than the assumed maximum wall thickness, the distal end side 10B of the cylindrical body part is left, but in that case, as shown in FIG. 4, the excess part 11 is cut so as to correspond to the wall thickness. Length adjustment is possible. That is, the extension length of the cylinder part 10 toward the other side of the wall can be changed.

  Further, a cut 12 along the outer circumference circle is formed as a groove on the outer periphery of the cylindrical portion 10 as shown in FIG. 5, and the cut 12 serves as a guide when a cutting tool such as a saw is applied. Therefore, cutting work becomes easy. Moreover, since the location where the cut line 12 is recessed is thin, the cutting becomes easier. Further, if the cuts 12 are arranged at equal intervals, the cuts serve as scales and positioning of the cutting position becomes easy.

  In addition, on the outer periphery of the cylindrical portion 10, four groove portions 13 are formed along the entire length of the cylindrical portion, and are recessed at substantially equal intervals on the circumference. As shown in FIG. 6, the groove 13 faces the distal end surface 14 of the cylindrical body 10, so that a lower hole 13 a for attaching the other side member 30 with the screw 1 is formed. When the cylindrical body portion 10 is cut for length adjustment, the groove portion 13 appears as the same screw lower hole 13a on the cutting surface 14a as the new tip surface 14. Further, these four groove portions 13 are formed in a shape facing the vertical direction in FIG. This is because when the cylindrical body portion 10 is molded, the direction of demolding can be set in two directions.

The other side member 30 is a joint 30a to which the wiring / piping material 2 is connected, or it is an outlet forming tool when these wiring / piping materials are inserted. Such other side member 30 is attached to the distal end surface 14 of the cylindrical body portion 10 with screws 1. In the case of the joint 30a, the joint 30a is attached to the front side of the wall. If the piping material 2 from the back of the wall is a water pipe, for example, a faucet is attached to the joint 30a. In the case of an outlet forming tool, the outlet is provided even when the water pipe on the back of the wall is pulled out directly to the wall surface.

  The one side member 20 is formed integrally with the cylindrical body portion 10 on the proximal end side 10 </ b> A of the cylindrical body portion 10, and has a substantially square shape that forms a flange shape of the cylindrical body portion 10. The one side member 20 is provided with screw grooves 21 at the four corners for screwing to the back of the wall. The screw groove 21 is formed in the vertical direction so that the vertical position of the one side member can be finely adjusted with the screw temporarily tightened.

  Moreover, as shown to FIGS. 7-8, the connection part 50 which connects the sheath pipe 40 and the penetration part formation member 100 to the surface 20a (back surface 20a) on the opposite side to the cylinder part 10 of this one side member 20. FIG. Specifically, three connection recesses 22 are provided on the back surface 20a for connection.

  The connecting portion 50 is arranged at a position where the sheath tube 40 arranged substantially at right angles to the cylindrical body portion 10 and the penetrating portion forming member 100, and has three connecting recesses on the one side member 20 side. The connection convex part 51 engaged with 22 is provided in three places. The connecting portion 50 connects the tubular body portion 10 and the sheath tube 40, but since the tubular body portion 10 and the sheath tube 40 are disposed at substantially right angles, the connecting portion 50 is flexible from the sheath tube 40 toward the tubular body portion 10. When the piping material 2 or the like is pushed out and inserted, the top of the piping material 2 is inserted while being grubbed. Therefore, as shown in FIG. 9, the inner surface 52 of the connecting portion 50 is curved and guided so that this curve can be made smoothly. Further, on the proximal end side 10A of the cylindrical body portion 10, the cylindrical body inner surface 15 is formed as a substantially continuous surface with the curved inner surface 52 of the connection portion 50 with some steps therebetween. Therefore, the continuous surface from this connection part 50 to the cylinder part 10 can loosen the curve compared with the case where a curved inner surface is provided only by the connection part inner surface. There is a possibility that the tip of the piping material 2 to be inserted when the curve is tight is supported by the curved inner surface 52 to be guided. However, if the curve is loose, such a possibility is lowered, and the insertion operation is performed well. It is.

  The usage method of such a penetration part forming member 100 is as follows.

  That is, the cylindrical portion 10 of the penetrating portion forming member 100 is cut to a length corresponding to the thickness of the target wall W. The cut cylindrical body portion 10 is inserted from the wall back Wa, and as shown in FIGS. 10 to 11, the screw 1 a is inserted into the screw groove 21 of the one side member 20 with the one side member 20 in contact with the wall back Wa. Is inserted and screwed.

In this way, the connection convex portion 51 of the connection portion 50 connected to the sheath tube 40 is connected to the one-side member 20 as the fixing portion with the one side Wa (wall back side) of the wall as the fixing destination. The arrangement is as shown in FIGS. 9 to 10 by engaging with 100 connection recesses 22. Next, the flexible piping material 2 is inserted into the sheath tube 40, and once extended to the distal end port 16 of the penetrating part forming member 100, the piping material 2 viewed through the distal end port 16 is pulled out by hand. 11 is connected to the joint 30a shown in FIG.

When piping and wiring are not performed by the sheath tube method, piping or the like may be performed directly without the sheath tube 40 of FIG. 7, and in that case, the connecting portion 50 may not be provided.

  In the joint 30a, one end of the cylindrical main body 31 is formed as a piping material mounting portion 32 to be fitted into the piping material 2, and the other end is formed as a male screw portion 33 for screwing the faucet. A circular flange portion 34 is provided in the middle of the cylindrical main body 31, and is screwed to the distal end surface 14 of the cylindrical body portion.

  The piping material 2 over the distal end port 16 is fitted with the piping material mounting portion 32 of the joint 30a. When the piping material 2 and the joint 30a are connected in this way, the piping material 2 is pushed back into the penetrating portion forming member 100, and the flange portion 34 of the joint 30a is covered with the front end port 16 of the cylindrical portion 10. Thus, the screw 1b is passed through the screw hole 38 provided in the flange portion 34, and the screw lower hole 13a appearing on the front end surface 14 is screwed.

  Actually, a packing ring 35 is inserted into the joint 30a, and the flange portion 34 is screwed to the distal end surface 14, so that as shown in FIG. 10, the flange portion 34 and the wall surface Wb. Thus, the packing ring 35 is sandwiched and plays a role of waterproofing so that rainwater or the like does not enter the through hole Wx of the wall W. The joint 30a has a male threaded portion 33 protruding on the wall surface Wb side, and a faucet or other equipment is screwed onto the joint 30a. The decorative ring 36 is inserted into the male threaded portion 33 of the joint 30a, and the nut 37 is screwed onto the joint ring 36 to complete the fitting.

  At this time, since the flange portion 34 is screwed to the cylindrical body portion 10, the flange portion 34 can be made smaller than the conventional one screwed to the wall W. In addition, when the flange portion 34 is reduced in this manner, the decorative ring 36 that covers the flange portion 34 can also be reduced, and the appearance can be improved.

  In addition, what is necessary is just to use as it is, without cut | disconnecting, when the length of the cylinder part 10 before a cutting | disconnection respond | corresponds to wall thickness. Even in the case of cutting, as long as the screw 1b reaches the screw hole 13a, the cutting surface 14a of the penetrating part forming member 100 may be cut at a position retracted from the wall surface Wb. Since the cutting position does not have to be exactly the same as the wall thickness, the cutting operation is facilitated accordingly.

  Further, even if the cut surface 14a is not perpendicular to the length of the cylindrical body portion 10 but is an oblique cut surface 14a, there is no problem as long as the screw 1b reaches the screw hole 13a. .

  In addition, as described above, in both cases of cutting less than the wall thickness or cutting obliquely, as long as the screw 1b reaches the screw hole and is screwed, the flange portion 34 of the joint 30a is attached to the wall surface. Therefore, there is no problem in fitting the joint. Further, no matter how cut, the packing ring 35 is sandwiched between the flange portion and the wall surface, so that waterproofing is not affected at all.

  Also, even if the through-hole forming member is mounted in an arrangement in which the cylindrical body portion is inclined (not right-angled) with respect to the wall surface, the screw for attaching the joint reaches the tip of the cylindrical body portion. As long as it can be screwed, the flange portion of the joint is pressed against the wall surface, the tubular body of the joint can also take a right angle to the wall surface, and there is no problem with waterproofing.

  In this embodiment, the penetration destination member 100 is fixed to the wall back Wa, but is not limited thereto. For example, when a wall consists of an outer wall and an inner wall and the penetration part forming member 100 is arranged on the inner wall, the wall may be fixed to the back of the outer wall.

  Further, the screw hole 13a may not be the groove portion 13 provided on the outer peripheral surface as in the present embodiment, for example, may be a groove portion provided on the inner peripheral surface, or a screw hole provided on the cylindrical wall instead of the groove portion. Also good.

  Example 2 relates to claim 2 and other inventions. FIGS. 12 to 13 show a penetrating part forming member provided with a substantially cylindrical cylindrical body part 10 and a square flange-shaped one side member 20 provided on the base end 10 </ b> A side of the cylindrical body part 10. 200. The difference of this embodiment from the first embodiment is that the one-side member 20 is separate from the cylindrical body portion 10. The cylindrical body portion 10 is the same as in the first embodiment in that it can be cut for length adjustment, except that the base end side 10A is simply cut off.

  Further, similarly to the first embodiment, four groove portions 13 along the entire longitudinal length of the cylindrical body portion are provided on the outer circumference of the cylindrical body portion 10 at substantially equal intervals. However, unlike the first embodiment, the groove portion 13 is formed so as to face the base end surface 17 of the cylindrical body portion 10, and a screw pilot hole 13 a that enables the screw attachment of the one side member 20 to the cylindrical body portion 10. Is supposed to form. And the groove part 13 appears as the screw lower hole 13a of the one side member 20 in the cut surface 17a which cut | disconnected the cylinder part 10. As shown in FIG.

  Further, the distal end surface 14 of the cylindrical body portion is provided with a separate member mounting portion provided with a screw lower hole 18 separately, and the other member 30 such as the joint 30a can be screwed as shown in FIG. It is like that.

  On the opposite side 20a of the one side member 20 to the cylindrical body portion 10, it is free to be able to connect the connection portion 50 similar to that in the first embodiment. In that case, as in the first embodiment, A connection structure with the connection unit 50 may be provided.

  The penetration part forming member 300 shown in Example 3 has the structure of Example 1 and Example 2 together.

  As shown in FIG. 14, the penetrating portion forming member 300 includes a cylindrical body portion 10 and a one-side member 20 that is separate from the cylindrical body portion 10. The cylindrical body portion 10 has four groove portions 13 along the entire length of the cylindrical body portion 10 and is recessed at substantially equal intervals on the circumference. However, the groove portions 13 are provided at both ends of the cylindrical body portion 10. Has reached. Therefore, the screw lower hole 13a in which the screw of the other side member 30 can be attached appears on the distal end side 10B by the groove portion 13, and the screw lower hole 13b in which the screw of the one side member can be attached appears on the proximal end side 10A. ing. When cutting into a length corresponding to the wall thickness, it is possible to cut either the proximal end side 10A or the distal end side 10B, or both. For example, when the wall thickness is thin, the original long cylindrical body portion 10 is cut and many cylindrical body portions 10 are cut out. It becomes such a case.

  The fourth embodiment relates to the invention of claim 6 and the like, and as shown in FIGS. 15 to 16, the through-hole forming member 400 is formed by screwing the cylindrical portion 10 and the cylindrical portion 10 together. And a box-like one-side member 20 to be connected.

  The cylindrical portion 10 is provided such that the groove 13 along the entire length of the cylindrical portion 10 reaches the distal end surface 14, and a male screw 18 is provided on the outer periphery of the cylindrical portion on the base end side 10 </ b> A. Yes.

  The one side member 20 has a box shape and is formed in a shape such that the box is placed on a flat surface such as a floor base. A female screw 23 to which the male screw 18 of the cylindrical body part 10 can be screwed is provided on the upper surface side of the box when placed, and the cylindrical part 10 and the one-side member 20 can be screwed together. The box is in communication. Further, a sheath tube connection portion 24 that enables communication connection with the sheath tube 40 is provided in a cylindrical shape on the side surface of the placed one-side member 20. The through-hole forming member 400 is attached at a stage where a floor base is completed, but a floor (a wall in an enlarged sense) stretched on the base is not yet constructed. That is, at the stage where the floor base is completed, the box-like one side member 20 is fixed to the base with screws or the like. Thereafter, the floor Wf is stretched, and at that time, a through hole for the cylindrical body portion 10 is also opened in the floor plate. When the floor Wf is stretched in this way, the distal end side 10B is cut to a length that does not come out on the floor when screwed through the through hole, the cylindrical body part 10 is inserted, and screwed into the one side member 20 to be attached. After that, a flexible piping material or the like is inserted from the side of the sheath tube 40 and is put on the distal end of the cylindrical portion 10. The removed piping material is pulled out, and the joint 30a is connected as in the case of the first embodiment, and this joint 30a is screwed to the distal end surface of the cylindrical body portion 10. After that, the decorative ring 36 may be inserted into the male screw of the joint 30 a from above and stopped with the nut 37.

  The fifth embodiment relates to the eighth aspect of the invention. As shown in FIGS. 17 to 18, the penetrating portion forming member 500 of this embodiment includes a cylindrical body portion 10 and a one-side member 20 that is a separate body from the cylindrical body portion 10.

  The cylindrical portion 10 is formed by detachably connecting cylindrical sections 10 'having the same shape. The cylinder section 10 ′ has a female screw 10 x formed on the inner periphery of the other side, and a male screw 10 y that can be screwed into the female screw 10 x formed on one side. Accordingly, since the cylinder sections 10 'can be connected to each other to form the cylinder body portion 10, the extension length of the cylinder body portion 10 toward the other side of the wall can be changed by adjusting the number of connections. It can be.

  Further, as shown in FIG. 19, four groove portions 13 along the longitudinal direction are formed on the inner surface of the cylinder section 10 ′ at substantially equal intervals on the circumference. The bulging part 13x which forms the bottom part of this groove part 13 is continuing in the longitudinal direction. The cylinder section 10 a ′ connected to the distal end side 10 </ b> B has the tip surface 14 of the cylinder section 10 a ′ also serving as the tip surface 14 of the cylinder section 10, but the groove 13 serves as the tip surface of the cylinder section 10. 14, the screw lower hole 13 a to which the screw of the other side member can be attached is formed.

  The screw hole 13a may be one in which the hole 13c is inserted through the thick portion of the cylinder section 10 'as shown in FIG. 20 instead of the groove 13 recessed in the inner surface as described above. Even in this case, the screw prepared hole 13a always appears on the distal end surface 14 of the cylindrical portion 10.

In this way, the length can be adjusted by connecting a plurality of tube segments 10 ', but the length adjustment unit can only be adjusted by an integral multiple of the length of the tube segments 10'. Therefore, if it is desired to make finer adjustments than this, the cylindrical section 10a 'connected to the distal end side 10B may be cut to an appropriate length. Thus, when the cylinder part 10 is cut | disconnected by length adjustment, the groove part 13 appears on the cut surface 14 as the same screw pilot hole 13a.

  The one side member 20 has a substantially square plate shape attached to the flange shape of the cylindrical portion 10 on one side of the cylindrical portion 10, and a female screw 10 y of the cylindrical section is screwed to one side of the plate surface. A possible female screw portion 23 projects in a cylindrical shape.

  The use of the penetrating part forming member with the above configuration is as follows.

  That is, the cylinder section 10 ′ is screwed into the one-side member 20, and the second and subsequent cylinder sections 10 ′ are connected by screwing to penetrate the wall thickness of the wall W as shown in FIG. The length of the part forming member 500 is matched. When the wall thickness is not an integral multiple of the cylinder section 10 ', the wall is connected to the length protruding to the wall surface Wb, and the protruding portion is cut so as to be within the wall thickness. The penetrating part forming member 500 whose length has been adjusted in this way is inserted from the wall back Wa side, and the one side member 20 is screwed to the wall back Wa. Thereby, the cylinder part 10 can be arrange | positioned in the through-hole Wx of the wall W. FIG.

  Note that the reference numeral Wy indicates a void Wy, which is used to secure a through hole Wx when a concrete wall or the like is placed. If the void Wy remains after the concrete is placed and cured. The inside of the void Wy becomes the through hole Wx. If the void Wy is removed, the concrete hole after the removal becomes the through hole Wx.

  When the penetrating part forming member 500 is arranged in the penetrating structure Wx of the wall W in this way, a sheath tube (not shown) arranged on the wall back Wa is connected to the base end side 10A by the same method as in the first embodiment. . Any connection method may be used, and connection may be made via the connection portion 50 in the same manner as in the first embodiment. In that case, the connection concave portion 22 may be provided in the one side member 20.

  Subsequent operations are the same as those in the first embodiment, that is, a flexible piping material or the like is inserted into the sheath tube and is inserted until it protrudes from the opening at the tip of the penetrating portion forming member 500. Then, the protruding piping material is pulled out to connect the joints, and the joints are screwed to the openings of the penetrating part forming member 500 to complete the operation.

  In addition, although the penetration part formation member provided with the cylinder part formed by connecting cylinder division body 10 'is equivalent to the Example of Claim 8, when cutting the cylinder part, it is Claim 1. This corresponds to this embodiment.

  The sixth embodiment relates to another aspect of the invention. Moreover, the penetration part formation member of this Example performs increase / decrease of the cylinder division body connected for length adjustment similarly to Example 5, on the base end side of a cylinder part. In other words, the cylindrical body portion is formed by detachably connecting a plurality of cylindrical sections on the base end side so that the extension length of the cylindrical body portion toward the other side of the wall can be changed.

  Therefore, a screw prepared hole that can be attached to the screw of the other side member is provided on the tip surface of the cylinder section located at the tip of the cylinder body. Further, a screw prepared hole for screwing the one end side member is provided on the proximal end side of the cylinder section.

For example, the one-side member may be provided with a hole in a substantially square plate-like material so that the female screw provided on one side of the cylinder section can correspond, and the hole is positioned at the base end. The female screw of the cylinder section to be inserted is inserted, and one side member is screwed into the screw hole of the cylinder section. After that, the same mounting work as in Example 5 may be continued.
In addition, when it becomes not suitable length only by the connection of a cylinder division body, what is necessary is just to cut | disconnect the cylinder part formed by connection similarly to Example 5. FIG. It is free to cut either one side or the other side.

  The present invention is not limited to the first to sixth embodiments, and may be implemented in any manner without departing from the gist of the invention. In Examples 1-6, although all use the joint for the other side member, it is good also considering a drawer outlet formation tool as the other side member. Although all of the examples are examples of inserting the piping material, wiring may be used instead of the piping material.
