  The present invention relates to a connection structure and a connection method for connecting a water supply pipe and a water faucet to each other.

  Conventionally, a synthetic resin water supply pipe that extends between a pair of wall bodies that constitute a wall of a building and are spaced apart from each other, and an end portion on which a male screw portion is formed is on one wall body side of the other wall body There is known a connection structure that connects a faucet arranged so as to penetrate from the opposite side (see, for example, Patent Document 1). This connection structure includes a pipe member for changing the direction of the flow path of the fluid guided to the water supply pipe toward the end of the water tap, and a metal connection for connecting the pipe member and the water tap to each other A tube.

  The pipe member is made of, for example, a synthetic resin such as polyvinyl chloride, and has a pipe body having an insertion end into which one end of the water supply pipe is inserted, and a female screw part embedded in the other end of the pipe body. And a female screw member made of a metal cylindrical body formed on the peripheral surface. There are a plurality of types of connecting pipes having different lengths, and various connecting pipes are selectively used according to the size of the interval between the other end of the pipe body and the end of the water tap. . A male threaded portion that can be screwed into the female threaded portion of the tube member is formed on the outer peripheral surface of one end of the connecting pipe, and a male threaded portion at the end of the water tap is formed on the inner peripheral surface of the other end of the connecting pipe. A female screw portion that can be screwed onto the screw is formed.

  In the illustrated example, the water supply pipe 11 is arranged in the outer peripheral wall 15 of the house. The outer peripheral wall 15 includes an outer wall body 16 disposed so as to be located on the outer side of the house, and an inner wall body 17 disposed on the outer wall body with an interval inward of the house. In the illustrated example, the water supply pipe 11 is made of a synthetic resin such as polyvinyl chloride, and is disposed between the wall bodies 16 and 17 so as to extend in the vertical direction along the wall body in the vicinity of the outer wall body 16. ing.

  As is well known in the art, the water tap 12 is formed of a metal material, and is a plug for controlling the flow rate of water supplied to, for example, a washroom (not shown) of a house through the water supply pipe 11. . The water faucet 12 has a connection end 18 connected to the connection pipe 14, and a male screw portion 19 threaded along the circumferential direction of the connection end 18 is formed on the outer peripheral surface 18 a of the connection end. ing. The water faucet 12 is disposed on the opposite side of the inner wall body 17 from the outer wall body 16 side so that the connection end 18 penetrates the through hole 20 formed in the inner wall body 17.

  The tube member 13 is made of a synthetic resin such as polyvinyl chloride, for example, and in the illustrated example, the tube member 13 is bent so that its longitudinal section is substantially L-shaped. An upper end portion 11a of the water supply pipe 11 is inserted into one end portion 13a of the pipe member 13, and an insertion end portion 23a of a connection pipe main body 23 described later of the connection pipe 14 is inserted into the other end portion 13b of the pipe member 13. The In the illustrated example, the inner diameters of the end portions 13a and 13b of the pipe member 13 are equal to each other.

  On the outer peripheral surface 13c of the other end portion 13b of the tube member 13, as shown in FIG. 2, the maximum value of the amount that can be inserted into the insertion end portion 23a of the connecting pipe body 23 into the other end portion 13b, that is, the maximum insertion amount. Is provided. The display portion 21 extends linearly along the axis of the other end portion 13b of the pipe member 13, and a marked line 21a indicating the maximum insertion position of the insertion end portion 23a of the connecting pipe main body 23, and the length of the marked line It is comprised with the number 21b which shows a dimension.

  In the illustrated example, an attachment seat 22 for attaching the tube member 13 to the attachment surface is provided on the outer peripheral surface 13 c of the one end portion 13 a of the tube member 13. The mounting seat 22 has a plate shape extending along the axis of the one end portion 13 a of the tube member 13, and the plate thickness direction is arranged so as to coincide with the radial direction of the one end portion 13 a of the tube member 13. In the example shown in FIG. 1, the pipe member 13 is disposed such that the other end portion 13 b faces the connection end portion 18 of the water tap 12 and the one end portion 13 a faces downward. And it fixes to this outer wall body by attaching to the inner surface 16a of the outer wall body 16 with a fastening member like a nut, or an adhesive agent.

  As shown in FIG. 1, a connecting pipe 14 for connecting the pipe member 13 and the water tap 12 to each other includes a cylindrical connecting pipe main body 23 and an inner peripheral surface 25a threaded to the male screw portion 19 of the water tap 12. And a cylindrical female screw member 25 in which a mating female screw portion 24 is formed.

  The connecting pipe main body 23 is formed of the same synthetic resin material as that of the pipe member 13. Moreover, the connecting pipe main body 23 has the above-mentioned insertion end 23a inserted into the other end 13b of the pipe member 13 at one end thereof, and the connection end 18 of the water tap 12 is inserted into the other end. It has a fitting end 23b. The length dimension along the axis of the connecting pipe main body 23 is set to the length dimension of the connecting pipe having the longest length dimension among a plurality of conventional connecting pipes having different length dimensions.

  As shown in FIG. 3, the outer peripheral surface 23c of the connecting pipe main body 23 is provided with a scale 26 for reading a length dimension along the axis of the connecting pipe main body 23 from the fitting end 23b. In the illustrated example, the scale 26 is attached at intervals of 1 cm.

  An attachment seat 27 for attaching the connection tube 14 to the attachment surface is provided on the outer peripheral surface 23c of the fitting end 23b of the connection tube main body 23. The mounting seat 27 has a plate shape extending along the axis of the connecting pipe main body 23, and is arranged with its plate thickness direction aligned with the radial direction of the connecting member 23.

  The female screw member 25 is formed of a metal material, and as shown in FIG. 1, its axis coincides with the axis of the connection pipe body 23 and the inner peripheral surface 15 a is exposed to the inside of the connection pipe body 23. The connecting pipe body 23 is embedded in the fitting end 23b. The internal thread member 25 is embedded in the connecting pipe main body 23 by, for example, well-known insert molding.

  When connecting the water supply pipe 11 and the water tap 12 to each other, first, the upper end portion 11 a of the water supply pipe 11 extending along the outer wall body 16 disposed before the inner wall body 17 is disposed is connected to one end portion 13 a of the pipe member 13. The water supply pipe 11 and the pipe member 13 are joined to each other by, for example, an adhesive (not shown). Further, in this state, the tube member 23 is fixed to the outer wall body 16 by attaching the mounting seat 22 provided at the one end portion 13 a of the tube member 13 to the inner surface 16 a of the outer wall body 16.

  Next, the insertion end portion 23 a of the connection tube main body 23 of the connection tube 14 is inserted into the other end portion 13 b of the tube member 13. At this time, when the distance L (see FIG. 1) between the other end portion 13b of the tube member 13 and the inner wall body 17 is smaller than the assumed interval size, the tube member 13 is connected to the other end portion 13b. The amount of protrusion of the connecting pipe body 23 from the pipe member 13 when the insertion end 23a of the pipe body 23 is inserted with the maximum insertion amount is based on the size of the interval between the outer wall body 16 and the inner wall body 17 disposed later. When the required distance L between the other end 13b of the pipe member 13 and the inner wall body 17 is larger than the required distance L, the protruding amount of the connecting pipe main body 23 from the pipe member 13 is adjusted.

  When adjusting the amount of projection of the connecting pipe main body 23 from the pipe member 13, first, the size of the interval L and the number 21b of the display portion 21 provided on the pipe member 13 are added together, and the value is connected. It reads from the scale 26 attached to the outer peripheral surface 23c of the pipe body 23. Next, the insertion end portion 23a is partially removed by cutting the connecting tube main body 23 between the position of the read scale 26 or the position of the scale 26 corresponding to the size of the interval L. To do. The connection pipe body 23 can be cut by a cutter (not shown), for example. By removing the insertion end portion 23a of the connecting pipe main body 23, the length dimension along the axis of the connecting pipe main body 23 is adjusted.

  After adjusting the length dimension of the connecting pipe main body 23, the insertion end 23a of the connecting pipe main body 23 is inserted into the other end 13b of the pipe member 13, and the protruding amount of the connecting pipe main body 23 from the other end is the above-described amount. The amount of insertion of the connecting pipe main body 23 into the other end 13b of the pipe member 13 is finely adjusted so as to be approximately equal to the size of the interval L. Thereby, adjustment of the protrusion amount of the connecting pipe main body 23 from the pipe member 13 is completed. Thereafter, the other end portion 13b of the pipe member 13 and the insertion end portion 23a of the connection pipe main body 23 are joined together by, for example, an adhesive. Thereby, the connecting pipe 14 and the water supply pipe 11 are connected to each other via the pipe member 13.

  Subsequently, the inner wall body 17 is arranged at a predetermined location. It is desirable to previously form the through hole 20 in the inner wall body 17 at a position corresponding to the fitting end portion 23 b of the connecting pipe main body 23. Since the protruding amount of the connecting pipe main body 23 from the other end portion 13a of the pipe member 13 is equal to the distance L, the inner wall body 17 is connected to the edge of the through hole 20 of the inner wall body 17 in a state where the inner wall body 17 is disposed. The fitting end 23b of the tube main body 23 contacts. Thereby, the through-hole 20 and the fitting end part 23b of the connecting pipe main body 23 are connected.

  Thereafter, the connection end 18 of the water tap 12 is inserted into the through hole 20 formed in the inner wall body 17, and the male screw portion 19 formed in the connection end 18 is embedded in the fitting end 23 b of the connection pipe body 23. The female screw member 24 of the female screw member 25 is screwed. Thus, the water tap 12 and the pipe member 13 are connected to each other via the connection pipe 14, and the water supply pipe 11 and the water tap 12 are connected to each other via the pipe member 13 and the connection pipe 14.

  According to the present embodiment, as described above, the connecting pipe main body 23 of the connecting pipe 14 for connecting the pipe member 13 and the faucet 12 to each other is made of synthetic resin, so that compared to the case where it is formed of metal. Thus, the connecting pipe body 23 can be easily cut. Further, since the insertion end portion 23a of the connection pipe main body 23 is inserted into the other end portion 13b of the pipe member 13, the insertion end portion 23a of the connection pipe main body 23 has a male screw portion formed on the conventional connection pipe. Since the screw part for connection with such a pipe member is not formed, the insertion end part 23a of the connection pipe main body 23 can be cut off without inhibiting the connection with the pipe member 13. Thereby, the length dimension along the axis line of the connecting pipe main body 23 can be adjusted easily.

  Accordingly, the size of the gap between the other end portion 13b of the pipe member 13 and the inner wall body 17 of the outer peripheral wall 15 is smaller than the assumed size, and the insertion end portion 23a of the connecting pipe main body 23 is replaced with the other end portion 13b of the pipe member 13. Even if the connecting tube body 23 is inserted at the maximum insertion amount, the insertion end of the connecting tube body 23 is inserted even when the protruding amount of the connecting tube body 23 from the tube member 13 is larger than the actual distance L between the tube member 13 and the inner wall body 17. 23a is cut and the connecting pipe main body 23 is inserted into the other end 13b of the pipe member 13, so that the amount of protrusion of the connecting pipe main body 23 from the other end 13b of the pipe member 13 is set to the other end 13b of the pipe member 13. Can be easily adjusted according to the actual size L of the gap between the inner wall 17 and the inner wall body 17.

  Thereby, even when the actual size L of the gap between the other end portion 13b of the tube member 13 and the inner wall body 17 is smaller than the assumed size, the connection tube main body 23 protrudes from the other end portion 13b of the tube member 13. Since it is not necessary to forcefully push the connecting pipe body 23 into the other end portion 13b of the pipe member 13 in order to adjust the amount, it is the same as in the prior art by forcing the connecting pipe body 23 into the other end portion 13b of the pipe member 13. Damage to the tubular member 13 can be reliably suppressed.

  Further, as described above, the scale 26 for reading the length dimension from the fitting end portion 23b of the connection pipe main body 23 is attached to the outer peripheral surface 23c of the connection pipe main body 23. The cutting position of the insertion end portion 23a of the connecting pipe main body 23 corresponding to the size of the distance L between the other end portion 13b and the inner wall body 17 can be easily recognized.

  Further, as described above, the display portion 21 indicating the maximum insertion amount of the insertion end portion 23a of the connection tube main body 23 to the other end portion 13b of the tube member 13 is provided on the outer peripheral surface 13c of the tube member 13. Therefore, when cutting one end portion of the connecting pipe body according to the size of the interval L, the other end portion of the pipe member 13 is calculated when calculating the length dimension from the one end portion of the connecting pipe body to the cutting position. The calculation can be performed in consideration of the amount of insertion of the insertion end 23a of the connecting pipe body 23 into 13b. Thereby, the length dimension from the fitting end part 23b of the connection pipe main body 23 to a cutting position can be calculated | required more correctly.

  In addition, as described above, the fitting end portion 23b of the connecting pipe main body 23 is provided with the mounting seat 27 for mounting the connecting pipe 14 to the mounting surface. When a building material 28 (see FIG. 1) is bridged between the surface 17 or the wall bodies 16, 17, a flow path of fluid guided to the water supply pipe 11 is formed on the lower surface 28 a of the building material. Accordingly, it can be easily fixed via the mounting seat 27. Further, since the attachment seat 27 is provided at the fitting end portion 23b of the connection pipe main body 23 that is not cut, the attachment seat 27 does not hinder cutting when the connection pipe main body 23 is cut.

  Furthermore, as described above, the tube member 13 is bent so that the cross section thereof is substantially L-shaped, and the mounting seat 22 for mounting the tube member 13 to the mounting surface is provided at one end portion 13a. Therefore, when the flow path of the fluid guided to the water supply pipe 11 is changed toward the inner wall body 17, the one end portion 13a of the pipe member 13 is directed upward or downward and the other end portion 13b is the inner wall body. By arranging the pipe member 13 so as to face the direction 17 and attaching the attachment seat 22 to the inner surface 16 a of the outer wall body 16, the pipe member 13 can be fixed to the outer wall body 16 via the attachment seat 22. Further, when the building material 28 is bridged between the wall bodies 16, 17, the one end 13 a is disposed so as to face the inner wall body 17, and the mounting seat 22 is attached to the lower surface 28 a of the building material 28. Thus, the pipe member 13 can be fixed to the building material 28 via the mounting seat 22. At this time, since each end part 13a, 13b of the pipe member 13 has an equal inner diameter as described above, the other end part 13b of the pipe member 13 and the water supply pipe 11 can be connected.

  In the present embodiment, the example in which the water supply pipe 11 is arranged in the outer peripheral wall 15 of the house is shown, but instead of this, the water supply pipe 11 may be arranged in the inner wall that partitions the room of the house. it can.

  Moreover, in the present Example, although the example which applied this invention to the connection structure 10 which mutually connects the water supply pipe 11 and the water tap 12 provided in a house was shown, it replaces with this and is provided in buildings other than a house. The present invention can be applied to a connection structure in which a water supply pipe and a water faucet are connected to each other.

It is a longitudinal cross-sectional view which shows roughly the connection structure of the water supply pipe and water tap which concerns on this invention. It is a top view showing roughly a pipe member concerning the present invention. 1 is a plan view schematically showing a connecting pipe according to the present invention.
