Description

  The present invention relates to a bathroom floor pan support frame for supporting a bathroom floor pan, and more particularly to a technique for easily pulling a tip of piping on the floor from a piping through hole of the bathroom floor pan.

  Conventionally, in the construction of unit bath piping, the upper end of piping such as water supply, hot water supply, and memorial service that has been set up from the floor is pulled out above the bathtub floor pan through the piping through hole provided in the bathtub floor pan. A construction method for connecting pipes above a pan is generally known.

  However, when the bathtub floor pan is installed, the piping through hole and the pipe start-up position are aligned from above the bathtub floor pan, and the bathtub floor pan is installed. It is difficult to align the start-up position of the pipe with the through-hole for piping, and after installing the bathtub floor pan, the position of the through-hole for piping and the upper end of the pipe may not match. It takes a lot of work to construct the bathtub floor pan, such as the need for detailed dimensions.

  Therefore, conventionally, an opening larger than the through hole for piping is formed in advance in the bathtub floor pan, and the opening is closed with a cover plate after the bathtub floor pan is installed (see, for example, Patent Document 1). ).

However, conventionally, as shown in FIG. 12, the bathtub floor pan 1 requires a large opening 50, and thus it is necessary to close the large opening 50 by the cover plate 52 after construction. In addition, in the case of a flexible pipe that is rolled instead of a non-flexible pipe where the pipe 10 on the floor is started up, for example, after the construction of the bathtub floor pan 1, an arm is inserted from the opening 50 to be flexible. The leading end of the flexible piping is pulled up to the upper part of the bathtub floor pan 1, or the arm is inserted from a large inspection port 51 provided near the opening 50 to open the leading end of the flexible piping. I try to pull it up from 50. For this reason, conventionally, the large opening part 50 and the large sized inspection port 51 are required, and there exists a problem that the design freedom of the bathtub floor pan 1 is restrict | limited largely. Furthermore, there may be no large inspection port 51 near the opening 50.

  The present invention has been invented in view of the above-described conventional problems, and the problem is that a bathroom floor is provided through a pipe through-hole provided in a bathroom floor pan with a pipe tip disposed along the floor. An object of the present invention is to provide a bathroom floor pan support frame that can be easily pulled out to the upper side of the pan, thereby greatly improving the workability and dramatically improving the degree of freedom in designing the bathroom floor pan. .

In order to solve the above-mentioned problem, the present invention is a bathroom floor pan support frame for supporting a bathroom floor pan 1 provided with a pipe through hole 2 through which a pipe 10 arranged along the floor passes. A floor pan support part 3 that is installed on the floor where the pipe 10 is arranged and supports the bathroom floor pan 1, and a lower position corresponding to the pipe through-hole 2 in which the tip 10 a of the pipe 10 is provided in the bathroom floor pan 1. A temporary pipe support means 4 for temporarily supporting the pipe, and the temporary pipe support means 4 is fixed to the floor pan support part 3 side and bound to the tip of a flexible pipe 10B that is rolled and piped on the floor. The pipe fixing band 6 and the band binding tool 7 that enables the pipe fixing band 6 to be released from above the pipe through hole 2 of the bathroom floor pan 1 are characterized.

By adopting such a configuration, the tip of the temporarily supported pipe 10 is always attached to the through-hole 2 for piping of the bathroom floor pan 1 simply by installing the bathroom floor pan 1 on the floor pan support 3 of the frame body 60. Therefore, it is easy to pull up the through-hole 2 for piping. Moreover, since it is the system which binds the front-end | tip part of the flexible piping 10B with the band 6 for piping fixation, it can be temporarily supported from which direction the flexible piping 10B is piped on the floor, and it does not come off in the middle of construction.

In order to solve the above-mentioned problem, the present invention is a bathroom floor pan support frame for supporting a bathroom floor pan 1 provided with a pipe through hole 2 through which a pipe 10 arranged along the floor passes. A floor pan support part 3 that is installed on the floor where the pipe 10 is arranged and supports the bathroom floor pan 1, and a lower position corresponding to the pipe through-hole 2 in which the tip 10 a of the pipe 10 is provided in the bathroom floor pan 1. The temporary pipe support means 4 is temporarily fixed to the floor pan support part 3 side, and the tip part of the flexible pipe 10B that is rolled on the floor is provided from above. The pipe fixing hook 8 is supported by being hooked and supported.

By adopting such a configuration, the tip of the temporarily supported pipe 10 is always attached to the through-hole 2 for piping of the bathroom floor pan 1 simply by installing the bathroom floor pan 1 on the floor pan support 3 of the frame body 60. Therefore, it is easy to pull up the through-hole 2 for piping. In addition, since the tip of the flexible pipe 10B is hooked and supported from above, the flexible pipe 10B can be temporarily supported from any direction on the floor, and the tip of the flexible pipe 10B. Unless it is lifted up, it will not come off during construction.

  The present invention, by temporarily supporting the tip of the pipe on the floor at a lower position corresponding to the through hole for piping provided in the bathroom floor pan, only by installing the bathroom floor pan on the floor pan support portion of the frame, The tip portion of the temporarily supported pipe is always located directly below the pipe through hole of the bathroom floor pan, and it is easy to pull up the pipe through hole. Therefore, it is not necessary to confirm whether the inflexible piping is set up in the correct position from the upper side of the bathroom floor pan when installing the bathroom floor pan, and to perform dimensioning work in advance. Is greatly improved. In addition, there is no need to provide a large opening through which the arm can be passed through the bathroom floor pan or a large inspection port through which the arm can be passed along the opening. The degree of freedom of design is greatly improved.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 shows a state in which the upper end portion of the pipe 10 from above the floor penetrates the pipe through-hole 2 of the bathtub floor pan 1A. FIG. 2 shows an example of the cylindrical portion 5 constituting the temporary pipe support means 4. 3 shows a state in which the upper end portion of the pipe 10 is temporarily supported on the tubular portion 5, and FIG.

  The bathtub-side frame body 60 of the present embodiment is disposed adjacent to the washroom floor pan 1B, and is a floor pan that supports the bathtub floor pan 1A provided with a through-hole 2 for piping through which the piping 10 disposed along the floor is passed. The support part 3 and the pipe temporary support means 4 which temporarily supports the front-end | tip part 10a of the pipe 10 arrange | positioned along a floor are integrally provided.

  The floor pan support portion 3 is formed in a square frame shape in plan view, and a temporary pipe support means 4 is provided on the side surface portion 3a.

  As shown in FIGS. 2 and 3, the temporary pipe support means 4 includes a cylindrical portion 5 disposed at a lower position corresponding to the through-hole 2 for piping provided in the bathtub floor pan 1 </ b> A, and the cylindrical portion 5. And a fixing tool 9 for fixing to the side surface portion 3 a of the floor pan support 3. The cylindrical portion 5 has a pipe shape that is slightly larger than the outer diameter of the distal end portion 10a of the pipe 10 and opens in the vertical direction.

  As shown in FIG. 2, the fixture 9 of this example has a pair of left and right arms 12 that are substantially parallel to each other outward from the left and right ends of the fixing portion 11 that is fixed to the side surface portion 3 a of the floor pan support portion 3. It protrudes and the cylindrical part 5 is attached to the front-end | tip of each arm 12, respectively. In addition, the fixture 9a located on the side of the corner portion 3b of the side surface portion 3a of the floor pan support portion 3 has a short arm 12 on the corner portion 3b side, and the cylindrical portion 5 attached to the short arm 12 is provided. It is made to oppose with the through-hole 2a for piping located in the corner part of 1 A of bathtub floor pans. In this example, when the bathtub floor pan 1 </ b> A is installed on the floor pan support portion 3, the tubular portion 5 is disposed at a height position where a certain gap is left without interfering with the bottom surface of the bathtub floor pan 1 </ b> A.

  Here, the pipes 10 arranged on the floor are the four inflexible pipes 10A (FIG. 3) that constitute the water supply and hot water supply pipes on the bathtub side and the washroom side, respectively. Four tubular portions 5 are provided, and four through holes 2 for piping are provided in the bathtub floor pan 1A. The non-flexible pipe 10A may be a steel pipe or a hard resin pipe.

  Next, an example of the construction procedure will be described.

  As shown in FIG. 2, each of the left and right end portions of the bathtub floor pan 1 </ b> A is provided with a set of four workpieces 61 in which the piping through holes 2 can be formed. A set of four workpieces 61 to be drilled is selected and drilled with a hole saw, and four piping through holes 2 are formed in advance on one end side of the bathtub floor pan 1A.

  First, the frame body 60 is installed on the floor. At this time, the upper ends of the four inflexible pipes 10A that stand up independently from the floor are respectively passed through the four cylindrical portions 5 attached to the side surface portion 3a of the floor pan support portion 3 (state shown in FIG. 3). ). Thereby, the upper end part of 10 A of inflexible piping is temporarily supported by the cylindrical part 5, and the starting position of each inflexible pipe 10A does not move in the middle of construction. Thereafter, the bathtub floor pan 1 </ b> A is placed on the floor pan support 3 of the frame body 60 from above. At this time, the upper end portion of the non-flexible pipe 10A temporarily supported by the cylindrical portion 5 always passes through the pipe through-hole 2 of the bathtub floor pan 1A and protrudes above the bathtub floor pan 1A (see FIG. 1 and the state of FIG. Thereafter, pipe connection work as usual is performed above the bathtub floor pan 1A.

  Therefore, the upper end portion of the non-flexible pipe 10A penetrates through the piping through hole 2 of the bathtub floor pan 1A simply by installing the bathtub floor pan 1A on the frame body 60 having the above configuration. It is not necessary to confirm whether the starting position of the non-flexible pipe 10A is in the correct position from the upper side and to perform prior dimensioning work, and the workability is greatly improved.

  Moreover, since it is not necessary to provide the large opening part 50 (FIG. 12) and the large sized inspection port 51 (FIG. 12) for letting an arm pass to the bathtub floor pan 1A conventionally, the freedom degree of design of the bathtub floor pan 1A. Will improve dramatically.

  Further, in this example, since the pipe temporary support means 4 that temporarily supports the non-flexible pipe 10A is constituted by the cylindrical portion 5, it can be temporarily supported with a simple structure and can be surely detached during the construction. Can be prevented.

  In this example, the non-flexible pipe 10A, such as a steel pipe or a hard resin pipe, is used as an example. However, for example, the tip of a foldable flexible pipe that is rolled on the floor is used. The same applies to the case where the cylindrical portion 5 is inserted and held from below.

  FIGS. 5-10 shows other embodiment of the temporary piping support means 4 same as the above. As shown in FIG. 6, the temporary pipe support means 4 of this example includes a pipe fixing band 6 that is bound to the tip of a flexible pipe 10 </ b> B that is rolled on the floor, and a pipe fixing band 6 that is connected to the floor pan. A fixing tool 9 (9a) for fixing to the side surface portion 3a of the support portion 3 and a band that enables unbinding of the pipe fixing band 6 from above the pipe through hole 2 of the bathtub floor pan 1A (see FIG. 1). It is composed of a binding tool 7. A flexible resin pipe is used as the flexible pipe 10B.

  The fixing tool 9 (9a) of this example has a pair of left and right arms 12 projecting substantially parallel from the left and right ends of the fixing portion 11 fixed to the side surface portion 3a of the floor pan support portion 3 toward the outside. A pin insertion portion 15 that is bent in an approximately L shape in plan view is formed at the tip of each arm 12 inward. FIG. 9 shows a fixture 9a positioned on the side of the corner 3b of the side surface portion 3a of the floor pan support 3, and the arm 12a on the side of the corner 3b is formed short to be attached to the short arm 12. The pin insertion part 15 is made to oppose with the piping through-hole 2a (refer FIG. 2) provided in the corner part of 1 A of bathtub floor pans. FIG. 10 shows the fixture 9 located on the center side of the side surface portion 3 a of the floor pan support 3.

  As shown in FIG. 8, the pipe fixing band 6 has a fixing piece 21 protruding from the upper end of a box-shaped band base 20 and fixed to the pin insertion part 15 of the fixing tool 9 (9a). Inside the banding root portion 20, an upper hole 22 opened upward at a position ahead of the fixing piece 21, and a lower end of the upper hole 22 and opened on both side surfaces of the banding root portion 20. A lateral through hole 23 is provided, and a band portion 24 that can be bent from an upper position than the lateral through hole 23 is extended on one side surface of the band root portion 20. A large number of binding pin holes 25 opened upward are formed.

  On the other hand, as shown in FIG. 6, the band binding tool 7 is either one of the grip part 26 to be gripped by hand and the band part 24 inserted through the upper hole 22 of the banding root part 20 and further penetrating the lateral through hole 23. A band-side insertion pin 28 to be inserted up to two binding pin holes 25 and a fixture-side insertion pin 27 to be inserted into the pin insertion portion 15 of the fixture 9 from above are integrally formed in a substantially h shape. .

  First, after installing the frame body 60 on the floor, the distal end portion of the flexible pipe 10 </ b> B that is rolled and piped on the floor is bound to the pipe fixing band 6. That is, as shown in FIG. 6 and FIG. 7A, a state where the distal end side of the band portion 24 is passed through the lateral through hole 23 of the banding root portion 20 and the distal end portion of the flexible pipe 10B is inserted into the ring. Then, when the band portion 24 is pulled and tightened, and the fixing device side insertion pin 27 of the band binding device 7 is inserted into the pin insertion portion 15 of the fixing device 9 in the direction of the arrow in FIG. By inserting the insertion pin 28 from above through the upper hole 22 of the banding root 20 into one binding pin hole 25, the pipe fixing band 6 binds the tip of the flexible pipe 10B. The state is held (the state of FIG. 7B).

  Thereafter, the bathtub floor pan 1 </ b> A is installed on the frame body 60. At this time, the distal end portion of the flexible pipe 10B temporarily supported by the pipe fixing band 6 is disposed opposite to the pipe through hole 2 of the bathtub floor pan 1A. If the grip part 26 of the band tie 7 is pulled up by hand in the direction of the arrow in FIG. 7C while grasping the tip of the flexible pipe 10B by hand, the fixing-side insertion pin 27 of the band tie 7 Is pulled out from the pin insertion portion 15 of the fixture 9 and simultaneously the band side insertion pin 28 is pulled out from the upper hole 22, so that the binding of the pipe fixing band 6 is released, and the distal end portion of the flexible tube 10B is removed. It can be pulled up above the through-hole 2 for piping.

  Therefore, unless the bundling of the pipe fixing band 6 by the band bundling tool 7 is released, the tip of the flexible pipe 10B does not come off during the construction. And since it is the system bundled with the band 6 for piping fixation, it can respond even if the flexible piping 10B is piped on the floor from which direction. Further, by forming the band tie 7 in a h-shape having a narrow width, the band tie 7 can be easily lifted upwardly so that the band tie 7 does not interfere with the pipe through-hole 2. There are also advantages.

  FIG. 11 shows still another embodiment of the temporary pipe support means 4 described above. The temporary pipe support means 4 of this example includes a pipe fixing hook 8 in which the tip of a flexible pipe 10B that is rolled on the floor is hooked and supported from above, and the pipe fixing hook 8 is connected to the floor pan support section 3. It is comprised with the fixing tool 9 fixed to side part 3a of this.

  In this example, the pin insertion portion 15 of the fixture 9 used in the embodiment of FIG. 5 is also used as the pipe fixing hook 8. On the other hand, a gripping piece 31 protruding upward with a masking tape 30 and one end of a hook-shaped locking pin 32 are attached to the tip of the flexible pipe 10B, and the other end of the locking pin 32 faces downward. It is held in a protruding state. Not only the locking pin 32, but also a portion provided on the distal end portion of the flexible piping 10B with a portion that is hooked and supported by the piping fixing hook 8 from above.

  After installing the frame body 60 on the floor, the distal end portion of the flexible pipe 10B can be hooked and supported by the pipe fixing hook 8 simply by inserting the locking pin 32 into the pipe fixing hook 8 from above. Thereafter, the bathtub floor pan 1 </ b> A is installed on the frame body 60. At this time, either a configuration in which the grip piece 31 is positioned directly below the piping through-hole 2 or a configuration in which the gripping piece 31 protrudes above the piping through-hole 2 in a state where the bathtub floor pan 1A is installed may be used. And after pulling up the grip piece 31 by hand and pulling out the tip of the flexible pipe 10B above the bathtub floor pan 1A, the masking tape 30 is peeled off and the grip piece 31 and the locking pin 32 are removed. The piping work of the flexible piping 10B is performed.

  Thus, by temporarily hooking and supporting the pipe fixing hook 8 from above, temporary support of the distal end portion of the flexible pipe 10B can be easily performed, and the pipe is provided below the pipe through hole 2 of the bathtub floor pan 1A. The distal end portion of the flexible pipe 10B hooked and supported by the fixing hook 8 can be made to oppose, and the flexible pipe can be obtained simply by putting a hand from above the through-hole 2 for the pipe, grasping the gripping piece 31 and pulling it up. The tip of 10B can be pulled up from the through-hole 2 for piping. Moreover, the tip of the flexible pipe 10B will not come off unless the tip of the flexible pipe 10B is pulled up during the construction. Moreover, there is an advantage that the flexible pipe 10B can be hooked and supported on the pipe fixing hook 8 regardless of the direction from which the flexible pipe 10B is piped on the floor.

  In the above embodiment, the frame body 60 that supports the bathtub floor pan 1A is exemplified as the bathroom floor pan support frame. However, the frame body can be similarly applied to the frame body that supports the wash floor pan 1B.
