Description

  The present invention relates to a flexible tube rising portion holder used for fitting and holding a curved rising portion when a flexible tube is raised and piped.

  As the conventional flexible tube rising part holder for the above-mentioned use, those disclosed in Patent Documents 1 and 2 are known. The structure common to the rising part holders disclosed in each of Patent Documents 1 and 2 is that a separate part is not required to hold the flexible tube with respect to the holder body, and it can be held only by the holder body. A flexible tube insertion portion for the purpose.

  For this reason, before fixing a holding tool to an installation surface, a flexible tube is inserted in the insertion part of the holder, and the flexible tube is bent while following the bent shape of the holder main body. Was fixed to the installation surface. Since flexible pipes such as water and hot water supply pipes have the necessary bending rigidity and bending bend, bending the flexible pipes according to the bending shape of the holder itself requires a large force. To do. And in order to set up the flexible tube, it is necessary to fix the holder to the installation surface while bending the flexible tube against bending rigidity, bending wrinkles, etc. of the flexible tube. The work of starting up the flexible tube requires a lot of work. In particular, in the so-called “sheath pipe construction method”, it is particularly difficult to bend the whole when the water supply / hot water supply pipe is inserted into the sheath pipe, that is, when the pipe is set up in a double pipe state.

  On the other hand, from the viewpoint of the construction sequence, it is necessary to perform the flexible tube piping and the fixing of the holder at the same time. There were also restrictions from the piping surface, such as being unable to do so.

  An object of the present invention is to make it possible to insert and hold a bent rising portion of a flexible tube to the rising portion holder after the rising portion holder is fixed to the installation surface.

  The invention of claim 1 for solving the above-mentioned problems is a holder main body for fitting and holding a curved rising portion of a flexible tube, and fixing for fixing the holder main body to an installation surface. A riser holder for a flexible tube provided with a seat, wherein the holder body has an arcuately bent shape from one end to the other end along the longitudinal direction, An insertion opening portion into which the rising portion can be inserted is provided, and the insertion opening portion is a direction perpendicular to the curved axis of the holder main body, and is a flexible tube from a direction that does not interfere with the fixed seat. Is formed over the entire length of the holder body.

  According to invention of Claim 1, the insertion opening part formed in the holder main body is a direction orthogonal to the bent axis of the holder main body, and from a direction that does not interfere with the fixed seat. Since it is formed over the entire length of the holder main body so that the flexible tube can be inserted, after fixing the holder to the installation surface via the fixing seat, it is attached to the bent axis of the holder main body. It is possible to insert a curved rising portion of the flexible tube into the insertion opening of the holder body from a direction orthogonal to the holder. Therefore, after fixing the holder to the installation surface, the operator bends the rising portion of the flexible tube with respect to the holder main body fixed to the installation surface, and the fitting opening formed in the holder main body. Therefore, it is possible to devote only to the work of inserting the rising part, so that the work of the rising pipe of the rising part of the flexible tube becomes easy. In this way, the installation and fixing work of the holder and the rising pipe work of the flexible pipe can be performed separately, so that the restriction on the piping when the flexible pipe is raised and piped is also eliminated.

  According to a second aspect of the present invention, in the first aspect of the invention, when the side on which the entire curved shape of the rising portion of the flexible tube appears is defined as the side surface, It is characterized in that it is formed so as to open on the side surface of the holder main body so that one side surface portion which is substantially half of the rising portion is fitted and held in the holder main body.

  According to invention of Claim 2, the insertion opening part formed in the holder main body in order to insert the curved rising part of a flexible tube is opening to the side of the said holder main body, The said holding | maintenance In the state where the bent rising portion of the flexible tube is fitted and held in the tool body, the bent rising portion is held by the holder main body over the entire length inside the bent state, so that the restoring force It is possible to effectively prevent a force of the bent rising portion of the flexible tube from coming off the holder main body. As a result, the rising portion of the flexible tube can be inserted into the holder main body only by inserting the bent rising portion of the flexible tube from the insertion opening portion opened in the side surface of the holder main body, without using other parts. Can be held. In addition, since the insertion opening formed in the holder main body for fitting the bent rising portion of the flexible tube opens to the side of the holder main body, the rising portion with respect to the holder main body The insertion work is also easy.

  Further, the invention of claim 3 is the invention of claim 2, wherein when the flexible tube is inserted into the holder body while bending the flexible tube at the central portion in the direction along the axis of the holder body, A bending fulcrum piece that acts as a bending fulcrum of the flexible tube is characterized by extending in a tangential direction that is opposite to the insertion direction of the flexible tube.

  According to invention of Claim 3, in order to make it insert in a holder main body, bending a flexible tube, the back surface side of the bending fulcrum piece provided in the center part of the direction along the axial center of the said holder main body In a state where a part of the flexible tube is supported, the flexible tube is bent until it has the same curvature as that of the holder body, and at that time, the rising portion of the bent flexible tube is moved to the holder body. When it is pushed into the inside, the flexible tube is inserted into the holder main body. For this reason, the operation | work which inserts the rising part which bent the flexible tube in a holder main body becomes easy. On the other hand, after the flexible tube is inserted into the holder main body, the bending fulcrum piece is effective in that the rising portion of the flexible tube bent and inserted into the holder main body is pulled out by its own elastic restoring force. The bending fulcrum piece extends in a tangential direction that is opposite to the insertion direction of the flexible tube with respect to the holder body. It does not become an obstacle when inserting.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the outer periphery of the rising portion is formed at both ends along the axis of the holder body at an angle exceeding 180 ° in a cross-sectional view. In order to be able to hold, a circumferentially extending portion is provided.

  According to invention of Claim 4, the both ends along the axial center direction of the curved rising part of the flexible tube hold | maintained at the holder main body are angles which exceed 180 degrees by sectional extension by a circumferential direction extension part. Thus, the outer periphery of the rising portion of the flexible tube can be held, so that the rising portion is prevented from coming out only by holding the rising portion of the flexible tube with the holder body. In particular, the combined use of a configuration in which a bending fulcrum piece extends in the insertion direction of the flexible tube at the central portion in the direction along the axis of the holder body can further effectively prevent the flexible tube from being pulled out.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the fixed seat includes an alignment portion that can be aligned with a ruled line marked on the installation surface. The alignment portion is characterized in that it is formed at the same position as the axial center of the vertical end surface of the holder body.

  According to the fifth aspect of the present invention, the pipe position of the vertical pipe portion of the flexible pipe that is piped up can be determined in advance, and the riser holder can be fixed to the installation surface. Becomes easy.

  The present invention provides a holder for a rising portion of a flexible tube, wherein the holder main body has a curved shape from one end to the other end along the longitudinal direction, and the rising portion of the flexible tube is inserted. A fitting tube that can be inserted from a direction that is perpendicular to the curved axis of the holder body and that does not interfere with the fixed seat. In this way, since it is formed over the entire length of the holder body, after the rising part holder is fixed to the installation surface, the bent part of the flexible tube is inserted into the rising part holder. Can be held. Therefore, the operator can separately perform the installation and fixing operation of the holding tool on the installation surface and the piping work for starting up the flexible tube, and the flexible tube having a large bending rigidity and bending bend. Since it is possible to concentrate on the piping work, it is easy to start up the flexible pipe, and the installation and fixing work of the fixture and the flexible pipe can be done separately. This restriction is also eliminated.

1 to 4 and 9, the rising portion holder A ₁ includes a holder main body 10 into which the sheath pipe P ₂ through which the water supply pipe P ₁ is inserted, and the holder main body 10 on the installation surface E. It comprises a fixed seat 40 for installation and fixing. In the following, simply as "the water supply pipe P ₁ is fitted into the holder main body 10" is meant to fit the water supply pipe P ₁ while inserting the water supply pipe P ₁ to sheath pipe P _2. The holder main body 10 has a shape obtained by cutting a ring semicylindrical body having a semicircular cross section that is open on one of the upper and lower surfaces so as to have a quadrant arc shape (center angle is approximately 90 °). The entire holder body 10 including the space is a portion that fits and holds the bent rising portion P ₁ a of the water supply pipe P ₁ . The holder main body 10 is substantially half of the rising portion P ₁ a of the water supply pipe P ₁ in a cross-sectional view when the side where the side where the entire shape of the rising portion P ₁ a of the water supply pipe P ₁ fitted and held appears is defined as a side surface. Is arranged in a form that is open to the side surface so as to be fitted into the holder body 10. A fixed seat 40 in the form of a plate is integrally formed through the opening-side connecting portion 12 and the non-opening-side connecting portion 13 at a portion extending from the center portion along the axial direction in the holder body 10 to the horizontally disposed side. Is provided. The opening along the axial direction (longitudinal direction) of the holder main body 10 is provided over the entire length along the axial direction, and the opening of the holder main body 10 having a quadrant in a side view is a side surface. The water supply pipe P ₁ inserted through the sheath pipe P ₂ is inserted into the holding body 10 from the side and is an insertion opening 14. Both end portions along the axial direction of the holder body 10 are linear portions in which both ends of a quadrant arc having a central angle of 90 ° are respectively extended in a tangential direction by a predetermined length.

The center part along the axial direction in the opening end surface 15a on the side of the fixed seat 40 of the opening end surfaces 15a and 15b forming the fitting opening 14 of the holder body 10 and forming a quadrant arc shape in a side view. In this case, the interference avoiding groove 16 is formed by being cut out in a wide groove shape by a predetermined center angle. The interference avoiding groove 16 avoids interference with the opening-side connecting portion 12 and ensures the fitting when the water supply pipe P ₁ inserted through the sheath pipe P ₂ is fitted into the holder body 10. Provided. On the other hand, the portion corresponding to the oblique upper portion of the interference avoidance groove 16 at the open end face 15b of the fixing seat 40 on the opposite side, a water supply pipe P ₁ that is fitted into the holder main body 10 with respect to the holder main body 10 A hooking groove portion 17 for hooking the binding band 1 for partial binding is formed. The oblique upper end of the interference avoidance groove 16 functions as a hook groove for hooking the binding band 1. Therefore, the opening-side connecting portion 12, because of the constraint that arranged forced to avoid interference with the holder main body 10 at the time of fitting the water supply pipe P ₁ to the holder main body 10, Both the length and the height along the axial direction of the holder main body 10 are shorter than the non-opening side connecting portion 13 without the restriction.

Further, a portion of the holder main body 10 forming the opening end surface 15a and having a predetermined length from both ends of the holder main body 10 toward the central portion has an angle θ ₁ exceeding 180 ° in a sectional view. circumferentially extending portion 10a of the circumferential length as capable of holding the water supply pipe P ₁ is formed longer in theta ₅ is provided. The circumferentially extending portion 10a has the longest circumferential length at the slightly inner portions of both ends, and the circumferential length along the axial direction gradually decreases toward the central portion in the axial direction. In FIG. 1, θ ₁ and θ ₅ are approximately 270 °, θ ₂ and θ ₃ are approximately 90 °, and θ ₄ is approximately 220 °. Here, when the water supply pipe P ₁ is inserted from the insertion opening 14 of the holder body 10, the portion of the holder body 10 that faces the insertion opening 14 is slightly expanded. It is elastically deformed so as to open (see the sectional view taken along line X ₁ -X _{1 in} FIG. 1), and the sheath pipe P ₂ through which the water supply pipe P ₁ is inserted is also deformed into a non-circular shape. With this configuration, even if the center angle of the insertion opening 14 of the holder main body 10 is smaller than 180 ° in almost all portions along the axial direction, water is supplied from the insertion opening 14 of the holder main body 10 to the inside. it is possible to fit the pipe P _1. Each opening end face 15a of the holder main body 10, on both end portions along the axial direction of 15b, in order to avoid being caught during the fitting of the water supply pipe P _1, cut into beveled respectively a side view and a front view It is missing.

Further, a side of the opening end face 15b of the holder main body 10 (the holder main body 10 Niwan song to fit the interior surface side of the water supply pipe P _1), in central axis direction, the water supply pipe P ₁ when to be fitted into the holder main body 10 by Owan song, the water supply pipe P ₁ of the bending and the holder bending fulcrum piece 18 to aid in both of the fitting of the water supply pipe P ₁ into body 10 is, the retainer It extends in the tangential direction which is the opposite direction to the fitting direction Q of the water supply pipe P ₁ with respect to the main body 10 (see FIGS. 4 and 5). For this reason, the bending fulcrum piece 18 does not become an obstacle when the water supply pipe P ₁ is inserted from the insertion opening 14 of the holder body 10. After the water supply pipe P ₁ is inserted into the holder body 10, the bending fulcrum piece 18 serves as a retaining piece that prevents the rising portion P ₁ a of the water supply pipe P _{1 from} coming out due to its own elastic restoring force. Fulfills the functions of

Further, as shown in the X ₂ -X ₂ line cross-sectional view of FIG. 1 and FIG. 9, it is a portion on the opposite side of the insertion opening 14 in the holder body 10, and the axial direction of the holder body 10 A protrusion 19 is formed along the axial direction in a portion corresponding to the hooking groove portion 17 along the axial direction, and at a position corresponding to the hooking groove portion 17 along the axial direction of the protrusion 19. , Another similar hooking groove 21 is formed. As shown in FIGS. 7 to 10, when the water supply pipe P ₁ is fitted in the holder body 10, the interference avoidance groove 16 and the hooking grooves 17 and 21 formed in the holder body 10 are bound. By inserting and hooking the band 1, the water supply pipe P ₁ fitted in the holder main body 10 is prevented from coming out.

Further, the height H ₁ (see FIG. 2) of the holder A ₁ is about 100 mm, which is much smaller than the height H ₂ (see FIG. 8) from the installation surface E to the back surface of the floor board 2. . Thus, the exposed portion to the retainer A ₁ and floor plate 2 of the water supply pipe P ₁ which is startup pipe is inserted into a self-supporting sleeve S, is to facilitate self vertical exposed pipe portion of the water supply pipe P ₁ . As shown in FIGS. 11 and 12, the self-supporting sleeve S is integrally formed with an outer fitting portion 32 having a slightly larger outer diameter than the sleeve main body 31 at the lower end portion of the cylindrical sleeve main body 31. A pair of engagement holes 33 are formed along the circumferential direction at portions facing the circumferential direction of the fitting portion 32, and the longitudinal direction of each engagement hole 33 is formed on the inner circumferential surface of the outer fitting portion 32. A protrusion insertion groove 34 connected to the end is formed. The pair of protrusion insertion groove portions 34 have a width that narrows from the opening end toward the inside. It said pair of projections insertion groove 34 corresponds to the pair of engaging projections 22 provided on opposing portions of the outer peripheral surface of the upper end portion of the holder main body 10 of the holder A _1. The sleeve body 31 is required to be the holder the height H ₁ and a length corresponding from the installation surface E at a height of H ₂ to the back surface of the floorboard 2 of the main body 10, the respective heights H _1, H _A scale 35 is provided on the outer peripheral surface along the length direction so as to be easily cut corresponding to ₂ .

Further, as shown in FIG. 3, the planar shape of the fixing seat 40 is a hexagonal shape, and the intersection 41 of two sides on the side where the vertical portion constituting one end portion in the axial direction of the holder body 10 is arranged. Is coincident with the axial center (center) C _{1 of} the end face 23 a having an incomplete ring shape on the vertical side of the holder body 10. Therefore, when installing fixing the retainer A ₁ for start-up the pipe the water supply pipe P ₁ to the installation surface E, to the installation surface E, the axis position of the vertical portion of the water supply pipe P ₁ is the start-up pipe When the fixed seat 40 is fixed to the installation surface E via a plurality of screws 3 in a state where the intersection 41 of the fixed seat 40 is aligned with the axial center position 4 (see FIG. 3), By simply fixing the fixed seat 40 to the installation surface E, the position of the axial center C ₁ of the vertical piping portion of the water supply pipe P ₁ to be erected is accurately determined. Therefore, it is possible to perform piping without making a mistake in the center position of the rising pipe portion when the water supply pipe P ₁ is piped up. 2, C ₂ indicates the axial center (center) of the horizontal end surface 23 b of the holder body 10. In FIG. 3, 42 indicates the insertion of the screw 3 that fixes the fixing seat 40 to the installation surface E. Indicates a hole.

Then, by using the rising portion holder A ₁ described above, the water supply pipe P ₁ inserted through the sheath pipe P ₂ to rise pipe is performed as follows. First, the position of the vertical pipe portion of the water supply pipe P ₁ is the rising pipe, since the water supply pipe P ₁ is previously known by the installation position of the washbasin or the like connected, a water supply pipe that is rising pipe at the installation surface E previously scribed a central axial position 4 of the vertical pipe portion of P _1. Then, with the intersection 41 of the fixed seat 40 of the holder A ₁ aligned with the ruled axial position 4 of the installation surface E, the fixed seat 40 is attached to the installation surface E using a plurality of screws 3. Fix (see FIG. 3).

After that, in order to fit the water supply pipe P ₁ into the holder body 10 while bending it, as shown in FIG. 5, a bend provided in the center portion in the direction along the axis of the holder body 10 is used. In a state where a part of the water supply pipe P ₁ is supported on the back side of the fulcrum piece 18, the water supply pipe P ₁ is bent until it becomes the same as the curvature of the holder body 10, and the bent water supply is made at that time. Engaging rising portion P ₁ a of the pipe P ₁ inside the holder main body 10, the water supply pipe P ₁ is inserted into the holder body 10 (see FIG. 6). Here, the central angle of the cross section of the central portion along the direction of the axial center where the bending fulcrum piece 18 of the holder main body 10 is provided is approximately 90 °, so that fitting is easy. Further, as shown in each of the cross-sectional views taken along lines X ₁ -X _{1 to} X ₅ -X ₅ in FIG. 1, the portion of the circumferentially extending portion 10 a facing the insertion opening 14 of the holder body 10 is inserted. The opening 14 is elastically deformed so as to expand, and the sheath pipe P ₂ through which the water supply pipe P ₁ is inserted is deformed into a non-circular shape so that the water supply pipe P ₁ and each rising portion P ₁ a sheath tube P _2, after the P ₂ a is fitted, by the holder main body 10 is restored to the original shape, more than half of the water supply pipe P ₁ and sheath pipe P ₂ in cross section One side surface portion is fitted into the holder body 10 over the entire length of the holder body 10 in the axial direction. Since the fitting opening 14 formed in the holder main body 10 is open on one side surface, the water supply pipe P ₁ and the sheath pipe P ₂ in a state where the water supply pipe P ₁ is fitted in the holder main body 10. Since the inner surfaces of the bent rising portions P ₁ a and P ₂ a are held over the entire length in the axial direction of the holder body 10, the bent water supply pipe P ₁ is returned to the original shape. Even if the elastic restoring force to act acts, the fitting state with respect to the holder body 10 can be maintained against the elastic restoring force. As described above, by using the bending fulcrum piece 18, the work of fitting the rising portion P ₁ a bent from the water supply pipe P ₁ into the holder body 10 is facilitated. In addition, after the water supply pipe P ₁ is inserted into the holder body 10, the bending fulcrum piece 18 has its own rising portion P ₁ a of the water supply pipe P ₁ bent and inserted into the holder body 10. The bending fulcrum piece 18 can be effectively prevented from slipping out due to the elastic restoring force, and the bending fulcrum piece 18 extends in a tangential direction that is opposite to the fitting direction of the water supply pipe P ₁ with respect to the holder body 10. The bending fulcrum piece 18 does not become an obstacle when the rising portion P ₁ a of the water supply pipe P ₁ is fitted. The water supply pipe P ₁ is inserted into the sheath pipe P ₂ except for a portion piped above the floor plate 2, but in FIG. 5 to FIG. 9, the sheath pipe P ₂ is only a part. Is shown.

As another method for fitting the rising portion P ₁ a of the water supply pipe P ₁ into the support tool body 10 using the bending fulcrum piece 18, the support tool body 10 is moved along the longitudinal direction by the bending fulcrum piece 18. fulcrum on one portion of bisected, after fitting the approximately half of the rising portion P ₁ a, by the bending fulcrum piece 18 by supporting the rest of the rising portion P ₁ a non fitting, the bending fulcrum piece 18 Then, the remaining rising portion P ₁ a that has not yet been inserted can be further bent, and then inserted into the other portion that is divided into two along the longitudinal direction of the support body 10. In this insertion method, since the rising portion P ₁ a of the water supply pipe P ₁ is inserted in two steps, the force required to bend the water supply pipe P ₁ is small and the insertion length is short. The work itself is easy.

Moreover, in addition to the fact that circumferentially extending portions 10a extending in the circumferential direction in cross-sectional view are formed at both end portions along the axial direction of the holder body 10, the transverse direction of the holder body 10 is formed. The surface has a central angle exceeding 180 ° over almost the entire length in the axial direction, and a bending fulcrum piece 18 is provided at the central portion of the holder body 10 in the axial direction (longitudinal direction). oriented in the direction of the insertion direction opposite to the rising portion P ₁ a of P ₁ are extended, the configurations described above can synergistically, water supply pipe P ₁ is inserted into the holder body 10 and the sheath pipe P ₂ Each of the rising portions P ₁ a and P ₂ a cannot be pulled out by the elastic restoring force. For this reason, it is only necessary to insert the rising portion P ₁ a of the water supply pipe P _{1 into} the holder main body 10 from the insertion opening 14 formed on the side surface of the holder main body 10, and use other parts at all. Instead, the rising portion P ₁ a of the water supply pipe P ₁ can be held with respect to the holder body 10. As shown in FIGS. 7 to 10, the binding band 1 is disposed in each of the hooking groove portions 17, 21 and the interference avoiding groove portion 16 formed in the holder body 10, and is fitted into the holder body 10. When the bent portion of the water supply pipe P _{1 is} bound to the holder main body 10 by the binding band 1, the bent portion of the water supply pipe P ₁ from the holder main body 10 can be reliably prevented.

Then, if necessary, a self-supporting sleeve S cut to a required length is externally fitted to the vertical portion of the upper end portion of the holder main body 10 to help the self-supporting of the vertical piping portion of the water supply pipe P ₁ . That is, a pair of protrusion insertion groove portions 34 formed in the outer fitting portion 32 at the lower end portion of the self-supporting sleeve S and a pair of engagement protrusions 22 formed in the vertical portion of the upper end portion of the holder body 10 are respectively provided. After fitting the external fitting portion 32 of the self-supporting sleeve S on the outside of the vertical portion of the upper end portion of the holder main body 10, the self-supporting sleeve S is attached to the holder main body 10 in the direction in which the engagement holes 33 are formed. When turned by a predetermined angle, the pair of engaging protrusions 22 of the holder main body 10 and the pair of engaging holes 33 of the self-supporting sleeve S are engaged, and the self-supporting sleeve S is perpendicular to the holder main body 10. The self-supporting sleeve S cannot be removed from the holder body 10 (see FIGS. 12A and 12B). Thus, the vertical pipe portion of the water supply pipe P ₁ that is inserted through the self-supporting sleeve S disposed vertically maintains vertical. In FIG. 8, 5 denotes an insertion hole of the water supply pipe P ₁ formed in the floor plate 2.

In addition, the present invention is characterized in that the work for fixing the rising portion of the flexible tube to the installation surface of the holder and the operation for fitting the rising portion of the flexible tube to the holder can be performed separately. The insertion opening formed in the holder main body for inserting the tube is not limited to the one opened on the side surface of the holder main body as in the above embodiment. For example, the flexible tube rising portion holder A ₂ shown in FIG. 13 has a configuration in which an insertion opening 14 ′ is formed on the inner surface side of the holder main body 10 ′. In the rising portion holder A ₂ , the bent rising portion P ₁ a of the water supply pipe P _{1 is} fitted from the front side of the holder main body 10 ′. At both ends in the axial direction of the holder main body 10 ', like the rising portion holder A ₁ described above, the circumferential extending portion 10'a is provided.

  Furthermore, the insertion opening formed in the holder body is formed between the side surface and the front surface of the holder body in addition to the form formed on the side surface of the holder body and the form formed on the front surface. The form, ie, the form opened on the oblique side surface, may be used. Except for the shape formed on the side surface of the holder body, the insertion opening may be pulled out by the elastic restoring force of the flexible tube simply by inserting the bent rising portion of the flexible tube. In that case, it is only necessary to prevent the flexible tube from coming out of the holder body by using a separate part such as a ring body. Even if it is configured to prevent the rising part of the flexible tube from coming out of the holder body using a separate part, the fixing work of the holding tool to the installation surface and the rising part of the flexible tube to the holder Can be inserted separately.

  Further, in the above-described piping example, after the holder is fixed to the installation surface, the rising portion of the flexible tube is inserted into the holder, but this may be reversed. That is, after the rising portion of the flexible tube is fitted in the holder, the holder in which the rising portion of the flexible tube is fitted can be fixed to the installation surface.

  In addition, the flexible pipe that is the object to be held by the riser holder according to the present invention is not limited to the water supply pipe inserted through the sheath pipe, but a water supply pipe whose outer periphery is covered with a heat insulating material, a similar hot water supply pipe, and an electric wire. And a single sheath tube. In the case of a single sheath tube, after being piped in a state where the rising portion is held by the holder, a water supply pipe or a hot water supply pipe is inserted into the sheath pipe.
