[0001] The present invention relates to a pipe holding band mounting fixture to which a pipe holding band for holding a pipe is attached. [Background technology]

[0002] BACKGROUND ART Pipe holding band mounting fixtures have been known which have mounting portions to which pipe holding bands for holding pipes can be attached. For example, Patent Document 1 listed below discloses a pipe support fixture that includes a pipe-holding band fixture having a base portion that is attached to the surface of an exterior wall and a strip-shaped mounting portion with one longitudinal end fixed to the base portion so as to protrude forward from the base portion, and a reinforcing member that is a separate member from the pipe-holding band fixture and that holds the mounting portion of the pipe-holding band fixture by clamping it in the thickness direction, thereby suppressing any shaking of the mounting portion in the thickness direction and preventing the mounting portion from bending or folding. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5877253 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the pipe support device of Patent Document 1, after the base portion of the pipe holding band mounting device was attached to the exterior wall, a reinforcing device that suppresses shaking of the mounting portion had to be fixed to the exterior wall using screws or the like.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and provides a pipe-holding band mounting fixture that can improve workability while suppressing deformation of the mounting portion, etc. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the pipe holding band mounting device of the present invention comprises a fixed portion that is fixed to an object to be fixed, and a plate-shaped mounting portion that protrudes from the fixed portion and to which a pipe holding band that holds a pipe is attached, and the mounting portion is characterized in that the base end on the fixed portion side is formed in a curved shape so that a groove extending in the protruding direction is formed on at least one side in the plate thickness direction, while both side surfaces in the plate thickness direction on the tip side in the protruding direction are flat. [Effects of the Invention]

[0007] Since the pipe-holding band mounting fixture of the present invention has the above-described configuration, it is possible to improve workability while suppressing deformation of the mounting portion. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an example of a pipe-embracing band mounting fixture according to an embodiment will be described with reference to the drawings. Note that in some drawings, some of the detailed reference numerals used in other drawings are omitted. 1 to 3 are diagrams showing an example and a modified example of the pipe holding band attachment according to the present embodiment.

[0010] 1 and 2, a pipe holding band mounting fixture 1 (hereinafter referred to as mounting fixture 1) according to this embodiment comprises a fixing part 2 that is fixed to a fixing object 9, and a plate-like mounting part 3 that protrudes from the fixing part 2 and to which a pipe holding band 4 that holds a pipe 5 is attached. With this configuration, the pipe 5 can be fixed to the fixing object 9 via the pipe holding band 4. Furthermore, the mounting portion 3 has a base end 31 on the fixing portion 2 side formed in a curved shape so that at least one thickness-wise surface 3a has a groove 33 extending in the protruding direction, while both thickness-wise side surfaces 3a, 3b on the tip end side in the protruding direction are flat. This configuration improves the strength of the base end 31 against loads generated in the thickness direction by wind, etc., without attaching a separate component, thereby suppressing deformation and damage, and improving workability. Furthermore, because both thickness-wise side surfaces 3a, 3b on the tip end side in the protruding direction are flat, it becomes easier to fit the pipe-holding band 4 so that it adheres closely to both thickness-wise side surfaces 3a, 3b on the tip end side in the protruding direction. An example of a specific configuration will be described below.

[0011] The fixture 1 is used, for example, to secure a downspout (pipe 5) that is arranged along the height direction of the exterior wall of a house or the like to drain rainwater downward, to the exterior wall (object to be fixed 9) via a pipe holding band 4. Note that the fixture 1 is not limited to being installed outdoors, and may also be used, for example, to secure piping that is installed indoors to transport fluids or the like. In order to secure the pipe 5 in a stable state, multiple fixtures 1 may be arranged at intervals along the longitudinal direction of the pipe 5.

[0012] The fixing portion 2 may be formed of a plate-like material made of metal such as stainless steel. In this embodiment, the fixing portion 2 is formed of a plate-like material that is rectangular when viewed in the thickness direction. The fixing portion 2 is provided with a plurality of circular through-holes 21 through which fasteners 6, such as bolts, are inserted to fix the mounting fixture 1 to the object 9 to be fixed. In this embodiment, the fixing portion 2 has an attachment portion 3 protruding along the thickness direction of the fixing portion 2 at the longitudinal center thereof. A pair of through-holes 21 are provided spaced apart from each other in the longitudinal direction of the fixing portion 2, sandwiching the attachment portion 3 therebetween. The through-holes 21 are also provided to penetrate the fixing portion 2 in the thickness direction. Note that the fixing portion 2 is not limited to a plate-like material that is rectangular when viewed in the thickness direction, and may be a square or circular plate-like material, or may be a block-like member made of a hard synthetic resin or the like. The means for fixing the fixing portion 2 to the object 9 is not limited to inserting the fasteners 6 through the through-holes 21, and various other means may be used.

[0013] The mounting portion 3 may be formed of a plate-shaped material made of metal such as stainless steel. In this embodiment, the mounting portion 3 is configured as a plate-shaped material that is rectangular when viewed in the plate thickness direction. In this embodiment, the plate thickness direction of the mounting portion 3 coincides with the longitudinal direction of the fixing portion 2, and the mounting portion 3 is provided so as to protrude from the center of the longitudinal direction of the fixing portion 2 along the plate thickness direction of the fixing portion 2. In other words, the mounting portion 3 is provided so as to protrude perpendicularly from one surface of the fixing portion 2 in the plate thickness direction. In this embodiment, the mounting portion 3 is formed with a plate thickness dimension that allows mounting piece portions 43, 43, described later, of the pipe holding band 4 to clamp the mounting portion 3.

[0014] The mounting portion 3 is formed by bending the base end portion 31 of a plate-shaped material having a uniform width along the protruding direction. This configuration can improve the yield of the plate-shaped material. For example, the yield can be improved by cutting out multiple rectangular plate-shaped materials (having a uniform width) from a metal plate that is rectangular when viewed in the plate thickness direction to form multiple mounting portions 3. Note that the width dimension of this plate-shaped material is the dimension in the plate width direction, which is perpendicular to the plate thickness direction of the mounting portion 3 and the protruding direction of the mounting portion 3. Furthermore, the mounting portion 3 of this embodiment has a bent base end portion 31 so that grooves 33 are formed on both side surfaces 3a, 3b in the plate thickness direction. This configuration can further improve the strength of the base end portion 31 against loads generated in the plate thickness direction.

[0015] The base end 31 of the mounting portion 3 is continuously curved along the plate width direction and has a wave-like shape when viewed in the protruding direction. The mounting portion 3 has grooves 33 defined by concave curved surfaces on both side surfaces 3a, 3b in the plate thickness direction. In this embodiment, the grooves 33 extend along the protruding direction of the mounting portion 3. A plurality of grooves 33 are arranged along the plate width direction of the mounting portion 3. The grooves 33 are alternately formed on one side surface 3a in the plate thickness direction and the other side surface 3b in the plate thickness direction along the plate width direction of the mounting portion 3. In the illustrated example, five grooves 33 are provided on each of the side surfaces 3a, 3b in the plate thickness direction. The longitudinal dimension of the grooves 33 is not particularly limited, and may be, for example, 1 / 5 to 1 / 3 of the protruding dimension of the mounting portion 3. The base end 31 of the mounting portion 3 is bent to form the grooves 33, thereby forming convex curved protrusions 32 on the opposite side of the grooves 33 in the plate thickness direction.

[0016] The base end 31 of the mounting portion 3 is formed so that its plate width dimension is smaller than that of the tip end in the protruding direction of the mounting portion 3. The base end 31 is also formed so that its plate width dimension gradually decreases toward the fixed portion 2. The groove 33 is formed so that its groove depth dimension gradually decreases toward the tip end in the protruding direction of the mounting portion 3. The protrusion 32 is formed so that its dimension along the plate width direction gradually decreases toward the tip end in the protruding direction.

[0017] The thickness dimension t2 of the base end 31, i.e., the dimension along the thickness direction between the protrusions 32, 32 on both side surfaces 3a, 3b of the base end 31, is greater than the thickness dimension t1 of the plate-shaped material constituting the mounting part 3. The thickness dimension t2 of the base end 31 may be a dimension that improves the strength of the base end 31 against loads acting in the thickness direction, compared to a configuration in which the base end is not bent. For example, the thickness dimension t2 of the base end 31 may be 1.3 to 3 times the thickness dimension t1 of the plate-shaped material.

[0018] The mounting portion 3 is provided with a long hole 34 extending in the protruding direction, closer to the tip in the protruding direction than the groove 33. Flat surface portions 36, 36 are formed around the long hole 34 on both side surfaces 3a, 3b in the plate thickness direction, to which the pipe holding band 4 can be fitted in close contact. The flat surface portions 36, 36 are formed to include the protruding tips of both side surfaces 3a, 3b in the plate thickness direction of the mounting portion 3. It is preferable that the protruding dimension of the flat surface portion 36 in this embodiment is equal to or greater than the mounting piece portion 43 of the pipe holding band 4, which will be described later.

[0019] If the mounting portion 3 is made of the same type of metal material as the fixed portion 2, it may be fixed to the fixed portion 2 by welding or by other fixing means. Furthermore, the fixed portion 2 and the mounting portion 3 may be molded as separate members from a hard synthetic resin, and the mounting portion 3 may be fixed to the fixed portion 2, or they may be molded integrally.

[0020] The pipe holding band 4 may be formed from a band-shaped material made of a metal such as stainless steel. As shown in FIG. 2 , the pipe holding band 4 includes a pair of band portions 42, 42 formed from the band-shaped material. The pair of band portions 42, 42 are connected by a hinge portion 41 provided at one end. The hinge portion 41 is provided so that its axis extends along the width direction of the band-shaped material constituting the band portion 42. The pair of band portions 42, 42 are configured to be openable and closable in the thickness direction of the band-shaped material constituting the band portion 42, about the hinge portion 41. The pipe holding band 4 is configured to be detachable from the pipe 5 by opening and closing the pair of band portions 42, 42 about the hinge portion 41. The pair of band portions 42, 42 are formed so that the inner peripheral surfaces of the band portions 42, 42 conform to the outer peripheral shape of the pipe 5 when closed. In the illustrated example, the band portion 42 is formed in an approximately semicircular shape so as to be able to hold a cylindrical pipe 5. The shape of the band portion 42 is not limited to a substantially semicircular shape, and for example, in the case of a pipe holding band 4 that holds a square cylindrical pipe 5, the band portions 42, 42 are formed in a rectangular shape.

[0021] The pipe-holding band 4 includes a flat mounting piece 43 extending from the other end of each band portion 42. The mounting piece 43 is a member that fits closely to the mounting portion 3 of the mounting fixture 1. The mounting piece 43 has a round through-hole 44 through which a bolt 7 is inserted. In the illustrated example, the mounting piece 43 has a pair of through-holes 44, 44 spaced apart in the direction of protrusion of the mounting piece 43. When the pipe-holding band 4 holds the pipe 5, the pair of mounting pieces 43, 43 clamp the mounting portion 3 of the mounting fixture 1, and the pipe-holding band 4 is fixed with bolts 7 and nuts 8 at appropriate locations in the elongated holes 34 of the mounting portion 3 through the two through-holes 44. In this manner, the mounting fixture 1 can secure the pipe 5 to the object 9 via the pipe-holding band 4. The pipe-holding band 4 may be formed of a hard synthetic resin. Alternatively, the through-holes 44 may be provided in each of the attachment pieces 43, 43, respectively.

[0022] Next, various modified examples of the pipe-embracing band mounting fixture according to this embodiment will be described with reference to Figure 3. In each of the following modified examples, the differences from the previously described example will be mainly described, and a description of the common configurations and effects will be omitted. 3(a) is a schematic diagram of a mounting fixture 1A according to a first modified example. Mounting fixture 1A differs from the previous example in that mounting portion 3 is fixed so that the plate width direction coincides with the longitudinal direction of fixing portion 2, and the configurations of the components of fixing portion 2 and mounting portion 3 are substantially the same as those of the previous example. In short, mounting fixture 1A of this modified example is configured such that mounting portion 3 of the previous example is fixed to fixing portion 2 in a state where it is rotated 90 degrees around the axis of the protruding direction. For example, if the mounting fixture 1A is used to fasten a downspout (pipe 5) arranged along the height direction of an exterior wall of a house or the like to the exterior wall (object 9 to be fixed) via the pipe holding band 4, the mounting fixture 1A is fixed to the exterior wall with the longitudinal direction of the mounting part 2 aligned with the longitudinal direction of the downspout (the height direction of the house). In such a case, if the entire mounting part 2 overlaps with the downspout when the exterior wall is viewed from the front, it will be difficult to see and will not spoil the aesthetic appearance of the house. In this way, if the mounting part 2 of the mounting fixture 1A is formed elongated in the thickness direction, the entire mounting part 2 will easily overlap with the pipe 5 when the object 9 to be fixed is viewed from the front, and will not spoil the aesthetic appearance of the object 9 to be fixed.

[0023] FIG. 3(b) schematically shows the base end 31 of the mounting portion 3A in the mounting tool 1B according to the second modification. Mounting portion 3A differs from the previous example in that one groove 33 is provided on each of both side surfaces 3a, 3b of base end 31 in the thickness direction. Base end 31 is formed in a substantially S-shaped corrugated shape when viewed in the protruding direction so that its thickness is two to three times the thickness of the plate-shaped material that constitutes mounting portion 3. Configuring base end 31 so that its thickness is two to three times the thickness of the plate-shaped material that constitutes mounting portion 3 improves strength against loads in the thickness direction.

[0024] FIG. 3(c) schematically illustrates the base end 31 of the mounting portion 3B in a mounting fixture 1C according to a third modification. The base end 31 of the mounting portion 3B differs from the previous example in that it is formed in a generally Z-shape when viewed in the protruding direction. The base end 31 has opposite ends 35A, 35B extending along the width direction of the mounting portion 3B. A connecting portion 37 inclined in the thickness direction of the mounting portion 3B is formed in the center of the base end 31 so as to connect the opposite ends 35A, 35B of the mounting portion 3B along the width direction. The connecting portion 37 is formed to connect one end in the thickness direction of the end 35A on one side of the mounting portion 3B along the width direction to the other end in the thickness direction of the end 35B on the other side of the mounting portion 3B along the width direction. The mounting portion 3B is partitioned into both ends 35A, 35B in the width direction of the plate and a connecting portion 37, and has grooves 33 extending in the protruding direction of the mounting portion 3B, one on each of the side surfaces 3a, 3b in the thickness direction of the base end 31. The mounting fixture 1C has both ends 35A, 35B in the width direction of the base end 31 formed to extend along the thickness direction of the mounting portion 3B, thereby improving strength against loads in the thickness direction.

[0025] FIG. 3(d) schematically shows the base end 31 of the mounting portion 3C in a mounting tool 1D according to a fourth modification. The mounting portion 3C differs from the previous example in that the base end 31 of the mounting portion 3C, as viewed in the protruding direction, is formed in a generally rectangular wave shape bent along the plate width direction. The base end 31 has two grooves 33 on the other side in the plate thickness direction and one groove 33 on one side in the plate thickness direction. The multiple grooves 33 are formed alternately on one thickness direction surface 3a and the other thickness direction surface 3b along the plate width direction of the mounting portion 3C. The groove 33 on one thickness direction side is provided in the center of the mounting portion 3C in the plate width direction, and the two grooves 33, 33 on the other thickness direction side are provided on both sides in the plate width direction of the mounting portion 3C. In the base end 31 of the mounting portion 3C, portions corresponding to the groove walls of the groove 33 are formed so as to extend along the plate thickness direction of the mounting portion 3, and portions corresponding to the groove bottom of the groove 33 are formed so as to extend along the plate width direction of the mounting portion 3. Both end portions 35A, 35B in the plate width direction of the mounting portion 3C are formed so as to extend along the plate thickness direction of the mounting portion 3C as portions corresponding to the groove walls of the groove 33. In the base end 31 of the mounting portion 3C, portions corresponding to the groove walls and portions corresponding to the groove bottom of the groove 33 are alternately formed along the plate width direction of the mounting portion 3C, so that the base end 31 is formed in a substantially rectangular wave shape when viewed in the protruding direction as described above. This improves strength against loads in the plate thickness direction.

[0026] The different configurations described in the above embodiments and modifications may be modified, rearranged, or combined as needed. Furthermore, the components constituting the pipe-holding band mounting fixture are not limited to the above configurations. For example, the base end of the mounting portion may have a groove formed on only one surface in the thickness direction. The base end may have any shape that improves strength against loads generated in the thickness direction. Furthermore, the fixing portion may have two or more pairs of through holes through which fasteners are inserted. [Explanation of symbols]
