Description

[Technical Field]

[0001] The present invention relates to a mounting body that constitutes a sleeve used for ventilation or for passing wiring or piping materials. [Background technology]

[0002] Conventionally, there have been wall-penetrating sleeves that can be attached by penetrating, for example, the exterior wall of a building (see, for example, Patent Document 1). As shown in FIG. 13, this wall-penetrating sleeve 21 is composed of an outer tube 22 having a flange 22a and an inner tube 23. By sliding the inner tube 23 relative to the outer tube 22, the extension length of the inner tube 23 from one end of the outer tube 22 can be changed, thereby adjusting the length of the wall-penetrating sleeve 21. Here, an engagement means is provided between the outer tube 22 and the inner tube 23. This engagement means consists of an engaging protrusion 22b provided on the outer tube 22 and an engaged recess 23a provided on the inner tube 23. A plurality of engaged recesses 23a are arranged in the axial direction, and the engaging protrusion 22b engages with one of the plurality of engaged recesses 23a, 23a, thereby maintaining the adjusted length of the wall-penetrating sleeve 21.

[0004] However, in the conventional wall-penetrating sleeve 21, the position of the flange 22a is fixed, and changing the position requires preparing an outer cylinder 22 that is suitable for each, which is troublesome.

[0005] This invention has been made to solve the above-mentioned conventional drawbacks, and its object is to provide an attachment body for a pipe material that constitutes a sleeve that allows the position of the flange portion to be set arbitrarily. [Means for solving the problem]

[0006] In order to achieve the above object, the mounting body for a pipe material according to the present invention has the following configuration: The invention of claim 1 provides a mounting body for a pipe material, which comprises a hollow cylindrical main body tube that forms a double-cylinder structure with the hollow cylindrical pipe material as the inner tube, and a plate-like flange portion that surrounds the main body tube and extends outward from the main body tube. The flange portion is provided with a pipe material indicator portion that indicates the position of one end of the pipe material, and a placement indicator portion that indicates the placement position of the mounting body relative to the one end of the pipe material.

[0007] According to this attachment to a pipe material, a flange portion is provided on the main tube, and the main tube forms a double-cylinder structure with the pipe material that serves as the inner tube. In this way, the main tube (attachment) with the flange portion and a general pipe material form a double-cylinder structure, so the flange portion can be provided at any position in the axial direction of the pipe material. Furthermore, the flange portion is provided with a pipe material indicator portion that indicates the position of one end of the pipe material and a placement indicator portion that indicates the placement position of the attachment to the one end of the pipe material. The pipe material indicator portion and the placement indicator portion make it easy to grasp the attachment position of the attachment to the pipe material.

[0008] In addition, the attachment to a pipe material according to the invention described in claim 2 is the attachment to a pipe material described in claim 1, wherein the placement indicator portion is arranged to indicate the position of at least one end of the main tube.

[0009] The pipe mount according to claim 3 is the pipe mount according to claim 1, wherein the main tube is formed to protrude on both sides of the flange portion in its thickness direction, and the position indicator portions are provided to indicate the positions of both ends of the main tube.

[0010] In addition, the attachment to a pipe material according to the invention described in claim 4 is the attachment to a pipe material described in claim 1, in which a window hole is provided in the main tube for visually checking a marking line drawn on the outer surface of the pipe material at a position indicated by the placement indicator portion.

[0011] Furthermore, the pipe mounting body according to the invention described in claim 5 is a pipe mounting body according to any one of claims 1 to 4, wherein the flange portion has a straight portion on its outer periphery, and the pipe material indicator portion and the placement indicator portion are provided along the straight portion. [Effects of the Invention]

[0012] According to the pipe mount of this invention, by combining a main tube (mount) provided with a flange with a general pipe, the position of the flange can be set arbitrarily relative to the pipe. Furthermore, the pipe indicator and placement indicator provided on the flange make it easy to grasp the mounting position of the mount relative to the pipe. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] 1 to 10 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a hollow cylindrical pipe material, 2 denotes a mounting body, and 3 denotes a flanged sleeve.

[0016] The mounting body 2 comprises a hollow cylindrical main body 4 that forms a double-cylinder state with the pipe 1 as the inner cylinder, and a plate-like flange portion 5 that surrounds the main body 4 and protrudes outward from the main body 4. The main body 4 is formed so as to protrude on both sides that sandwich the flange portion 5 in its thickness direction. Here, the flange portion 5 is provided with a pipe index portion 11 that indicates the position of one end 1x of the pipe 1, and an arrangement index portion 12 that indicates the arrangement position of the mounting body 2 relative to the one end 1x of the pipe 1.

[0017] Specifically, the placement indicator portion 12 is provided so as to indicate the position of at least one end 4x of the main body tube 4. In the illustrated embodiment, the placement indicator portion 12 is provided so as to indicate the positions of both ends 4x, 4x of the main body tube 4.

[0018] Furthermore, the flange portion 5 has a straight portion 5c on its outer periphery, and the pipe material indicator portion 11 and the arrangement indicator portion 12 are provided along the straight portion 5c.

[0019] The flanged sleeve 3 comprises the pipe material 1 and the mounting body 2. With one end 1a of the pipe material 1 protruding from one end 4a of the main tube 4, adhesive tape (not shown) is wrapped around the outer circumferential surface of one end 4a of the main tube 4 and the outer circumferential surface of the pipe material 1, thereby integrating the mounting body 2 and the pipe material 1.

[0020] Specifically, the pipe material 1 is made of, for example, synthetic resin, and has a uniform cross section, a cylindrical shape, and smooth inner and outer surfaces.

[0021] The mounting body 2 is made of, for example, synthetic resin. The main body tube 4 of this mounting body 2 has a constant cross section and is cylindrical. To obtain a drainage gradient for the pipe 1, the axis of the pipe 1 (and therefore the axis of the main body tube 4) and the flange portion 5 of the mounting body 2 are inclined and not perpendicular to each other. The flange portion 5 of this mounting body 2 is formed in a rectangular shape with four straight portions 5c, 5c on its outer periphery. The pipe material indicator portion 11 and the placement indicator portion 12 are provided along one of the four straight portions 5c, 5c, and in particular, on one side surface 5b, which is the front surface of the flange portion 5. The pipe material indicator portion 11 has a scale 11a that indicates the length from a predetermined location on the mounting body 2 (in the illustrated embodiment, the other side surface 5d, which is the back surface of the flange portion 5) to the one end 1x of the pipe 1 (more specifically, the one end located on the side where one side surface 5b (front surface) of the flange portion 5 is located, i.e., the front end). In the illustrated embodiment, as shown in Figures 7 and 8, one end 1x of the pipe material 1 is aligned with the "30" position on this scale 11a, and the length from the other surface 5d (back surface) of the flange portion 5 of the mounting body 2 to the one end 1x of the pipe material 1 is set to 30 mm. As described above, the arrangement indicator portions 12 indicate the positions of both ends 4x, 4x of the main tube 4 of the mounting body 2, and are provided in two locations, and a score line 1y is drawn on the pipe material 1 in line with these arrangement indicator portions 12. In the illustrated embodiment, the arrangement indicator portions 12 are indicated by lines (more specifically, lines formed by steps).

[0022] The mounting body 2 is also provided with a slit 6, which consists of a first slit 6a that extends along the axial direction of the main body tube 4 and slits the peripheral wall of the main body tube 4, and a second slit 6b that extends from the first slit 6a along the protruding direction of the flange portion 5 and slits the flange portion 5, and by opening the slit 6, the pipe material 1 can be placed inside the main body tube 4 through the opened opening. Then, on the side of the flange portion 5 opposite to the side where the second slit 6b is located, a notch 5a is formed that is cut from the edge of the flange portion 5.

[0023] A drain wall 7 is provided so as to protrude from one surface 5b (front surface) of the flange portion 5. This drain wall 7 includes a first drain wall 7a that surrounds the inner space of the main body tube 4, and a pair of second drain walls 7b, 7b that are continuous with the first drain wall 7a and extend in the protruding direction of the flange portion 5 along the second cutout 6b on both sides of the second cutout 6b.

[0024] As described above, the main body tube 4 is formed so as to protrude on both sides of the flange portion 5 in its thickness direction. The portion of the main body tube 4 protruding on one side serves as the first drain wall 7a. In other words, the portion of the main body tube 4 protruding from one surface 5b (front surface) of the flange portion 5 also serves as the first drain wall 7a. The second drain wall 7b extends along the second cutout 6b to the protruding edge of the flange portion 5. The opposing surfaces M1, M1 of the pair of second drain walls 7b, 7b are located on the same plane as the opposing surfaces M2, M2 of the second cutout 6b (see FIG. 6).

[0025] Furthermore, the flange portion 5 is rectangular, and one side surface 5b (front surface), in particular the edge portion of the flange portion 5, is configured as a flat surface so that waterproof tape can be applied across one side surface 5b (front surface) of the flange portion 5 and the front surface of the structure with the other side surface 5d (back surface) of the flange portion 5 facing the front surface of the structure. In particular, it is desirable to arrange a pair of parallel rectangular straight line portions 5c, 5c of the flange portion 5 so that they are perpendicular, and to apply waterproof tape to the pair of perpendicularly arranged straight line portions 5c, 5c and the upper straight line portion 5c of the pair of horizontal straight line portions 5c, 5c, and the edge portions of the flange portion 5 on the side of these three straight line portions 5c, 5c (i.e., the three excluding the lower straight line portion 5c) are configured as flat surfaces.

[0026] Furthermore, the flange portion 5 has a fixing portion 5e (a concave fixing portion in the illustrated embodiment) through which a fastener such as a screw or nail that is screwed or driven into the structure passes when the other surface 5d (back surface) of the flange portion 5 is placed against the front surface of the structure, and the flanged sleeve 3 can be fixed to the structure by the fixing portion 5e. As another fixing method, one surface 5b (front surface) of the flange portion 5, particularly the edge portion of the flange portion 5, is configured as a flat surface so that the other surface 5d (back surface) of the flange portion 5 can be fixed to the front surface of the structure with adhesive tape that spans the one surface 5b (front surface) of the flange portion 5 and the front surface of the structure. Here, this adhesive tape can be used in combination with the waterproof tape described above.

[0027] 9 and 10 show the flanged sleeve 3 installed on a wall 15. The wall 15 is composed of an outer wall 16 and an inner wall 17 (corresponding to the structure described above), and the inner wall 17 has an outer first wall 17a and an inner second wall 17b. A through hole 15a is formed in the wall 15, and this through hole 15a has an outer wall hole 16a in the outer wall 16 and an inner wall hole 17c in the inner wall 17. As shown in FIG. 9, the flanged sleeve 3 is attached to the inner wall 17, and before or after this, one end 1a of the pipe 1 is cut off and removed from the flanged sleeve 3 to obtain an appropriate length. During this installation, the pipe 1 and main tube 4 are inserted into the inner wall hole 17c from the outside of the inner wall 17, and the other surface 5d (back surface) of the flange 5 is positioned against the outer surface 17d (front surface) of the inner wall 17, which is the structure. At this time, the slit 6 and the second drip wall 7b are positioned downward. The flanged sleeve 3 is then attached and fixed to the inner wall 17 using fasteners such as screws or nails that penetrate the flange 5 and are screwed or driven into the inner wall 17 (specifically, the first wall 17a). Then, as shown in FIG. 10 , the outer wall 16 is installed, and the inside of the pipe 1 faces the outside of the wall 15 (specifically, the outer wall 16) through the outer wall hole 16a. A hood 18 is attached to the outer wall 16 at the position of the outer wall hole 16a so that a portion of it is inserted into the pipe 1, and a ventilation fan (not shown) is installed at the back of the pipe 1.

[0028] Next, the effects of the mounting body 2 configured as described above will be explained. According to this mounting body 2, the main tube 4 is provided with a flange portion 5, and the main tube 4 forms a double-cylinder state with the pipe material 1 that serves as the inner tube. In this way, the main tube 4 (mounting body 2) provided with the flange portion 5 and the general (general-purpose) pipe material 1 form a double-cylinder state (i.e., the pipe material 1 passes through the main tube 4 (mounting body 2)), so the mounting body 2, and therefore the flange portion 5, can be provided at any position in the axial direction of the pipe material 1. In addition, the flange portion 5 is provided with a pipe material indicator portion 11 that indicates the position of one end 1x of the pipe material 1, and a placement indicator portion 12 that indicates the placement position of the mounting body 2 relative to the one end 1x of the pipe material 1, and the mounting position of the mounting body 2 relative to the pipe material 1 can be easily grasped using these pipe material indicator portion 11 and placement indicator portion 12 (more specifically, by aligning one end 1x of the pipe material 1 with the pipe material indicator portion 11 and drawing a line 1y at the position indicated by the placement indicator portion 12 of the pipe material 1).

[0029] That is, by combining the main tube 4 (mounting body 2) provided with the flange portion 5 with a general (general-purpose) pipe material 1, the position of the flange portion 5 can be set arbitrarily with respect to the pipe material 1, and further, the length of the flanged sleeve 3 can be freely adjusted. Furthermore, the pipe material indicator portion 11 and the arrangement indicator portion 12 provided on the flange portion 5 make it easy to grasp the mounting position of the mounting body 2 with respect to the pipe material 1.

[0030] The mounting body 2 also has a slit 6, which can be opened to allow the pipe 1 to be placed inside the main tube 4. This slit 6 allows the main tube 4 to be placed directly at a midpoint on the pipe 1, making the process easier than fitting the main tube 4 from the end of the pipe 1 and then moving it. In particular, when adhesively fastening the two together, moving the main tube 4 (mounting body 2) from the end of the pipe 1 to the bonding position can result in adhesive adhesion. However, by placing the main tube 4 (mounting body 2) directly at a midpoint on the pipe 1, this does not occur. The flange 5 also has a slit 5a formed on the side opposite the second slit 6b. This slit 5a absorbs distortion of the flange 5 that occurs when the outer diameter of the inner pipe 1 is slightly larger and the opened slit 6 cannot be returned to its original position. This allows the flange 5 to be kept distortion-free or with minimal distortion, making it possible to accommodate slight differences in the outer diameter of the pipe 1. Therefore, when the flange portion 5 (more specifically, the other surface 5d (back surface) of the flange portion 5) is placed against the outer surface 17d (front surface) of the inner wall 17 (structure), it can be stabilized with no gap between it and the inner wall 17 (structure).

[0031] Furthermore, by providing the drain walls 7 (first drain wall 7a, second drain wall 7b) on one surface 5b (front surface) of the flange portion 5, rainwater can be blocked and prevented from seeping in through the slit 6. Furthermore, by positioning the second drain wall 7b on the lower side of the flange portion 5 (that is, by positioning the slit 6 on the lower side), the second drain wall 7b does not get in the way when applying waterproof tape (adhesive tape) to the top and left and right positions across the flange portion 5 and the inner wall 17 (structure) to which the flange portion 5 (more specifically, the other surface 5d (rear surface) of the flange portion 5) is attached.

[0032] Furthermore, the opposing surfaces M1, M1 of the pair of second drain walls 7b, 7b are located on the same plane as the opposing surfaces M2, M2 of the second slit 6b, which ensures a wide bonding surface when bonding to close the slit 6, including the opposing surfaces M1, M1 of the pair of second drain walls 7b, 7b.

[0033] The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the axis of the pipe 1 (i.e., the axis of the main cylinder 4) and the flange portion 5 of the mounting body 2 are tilted and not perpendicular to each other, but they may be perpendicular to each other.

[0034] Furthermore, the main body tube 4 is formed so as to protrude on both sides sandwiching the flange portion 5 in its thickness direction, but as shown in Figure 11, the part of the main body tube 4 that also serves as the first drain wall 7a may be omitted, and in this case, one of the ends 4x, 4x of the main body tube 4 indicated by the placement indicator portion 12 will be on one side surface 5b (front surface) of the flange portion 5.

[0035] Furthermore, although the placement indicator portion 12 is provided so as to indicate the positions of both ends 4x, 4x of the main body tube 4, it may also be configured to indicate the position of only one end 4x.

[0036] Furthermore, the placement indicator portion 12 does not have to be arranged to indicate the position of the end 4x of the main body tube 4, and may be arranged to indicate, for example, the position of the flange portion 5 (in the illustrated embodiment, the other side surface 5d (back surface)). In such a case, as shown in Figure 12, a window hole 4z is provided in the main body tube 4, and this window hole 4z serves as a hole for visually checking the marking line drawn on the outer surface of the pipe material 1 at the position indicated by the placement indicator portion 12.

[0037] Furthermore, the first drain wall 7a is formed by the peripheral wall of the main body tube 4 protruding from one surface 5b of the flange portion 5, but the first drain wall 7a may be formed around the outside of the main body tube 4 protruding from one surface 5b of the flange portion 5 separately, or the first drain wall 7a may be formed independently of the main body tube 4 without protruding from one surface 5b of the flange portion 5. Furthermore, the second drain wall 7b extends until it reaches the edge of the flange portion 5, but it may also extend just before reaching the edge (particularly, just before reaching the edge at a position outside the inner wall hole 17c (wall hole)).

[0038] In addition, the mounting body 2 and the pipe material 1 are integrated (fixed) together by adhesive tape that spans the main tube 4 and the pipe material 1, but they may also be integrated (fixed) together by adhesive, or they may be integrated (fixed) together by both.
