Description

The present invention relates to a piping fixture for fixing piping to a wall surface.

BACKGROUND ART Piping fixtures for fixing piping to a wall surface (for example, a floor surface, a ceiling surface, a side wall surface) are conventionally known. The piping fixture mainly includes, for example, a base plate and a band-shaped belt protruding from the base plate (see, for example, Patent Documents 1 and 2). Such a piping fixture is installed on a wall surface, for example, by the following procedure.

First, a wall surface is irradiated with a laser beam that indicates the center position of the pipe to determine the installation position of the pipe fixture. Next, bolt holes for fixing the piping fixtures are formed in the wall surface. Next, a belt is wound around the installed piping, and bolts inserted through through holes provided in the base plate and the belt are screwed into the bolt holes. Thereby, the piping fixture holding the piping is fixed to the wall surface.

In the above installation procedure, in order to determine the installation position of the piping fixture, it is necessary to know where in the piping fixture the center of the piping (that is, the laser beam) passes. However, this information is listed as specifications in the catalogs and instruction manuals of piping fixtures, so workers decide on the installation location of piping fixtures by comparing these documents with the actual installation location. There is a need.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a piping fixture that allows installation work to be performed easily and accurately.

In order to solve such technical problems, the present invention provides a base plate in which a first through hole and a second through hole are formed at positions spaced apart in a first direction, and a base plate in which a first through hole and a second through hole are formed in positions spaced apart from each other in a first direction. a belt-shaped belt that protrudes from the upper surface of the base plate and is wound around a pipe that extends in a second direction perpendicular to the first direction; a fixing piece in which a fixing through hole is formed that can communicate with the second through hole when the belt is wound around the belt, and a side surface of the base plate indicates the center position of the piping around which the belt is wound. It is characterized by the formation of piping marks.

According to the present invention, installation work can be performed easily and accurately.

Hereinafter, a piping fixture 1 according to an embodiment will be described based on the drawings. Note that the embodiments of the present invention described below show an example of embodying the present invention, and the scope of the present invention is not limited to the range described in the embodiments. Therefore, the present invention can be implemented by adding various changes to the embodiments.

FIG. 1 is a perspective view of the piping fixture 1 viewed from the front side. FIG. 2 is a perspective view of the piping fixture 1 viewed from the rear side. FIG. 3 is a left side view of the piping fixture 1. FIG. 4 is a bottom view of the piping fixture 1.

In this specification, the side where the inclined surface 19 and guide piece 40 described later are provided is defined as the "front" of the piping fixture 1, and the side where the through hole 11, which will be described later, is provided is defined as the "rear" of the piping fixture 1. Then, the left and right directions are defined when the piping fixture 1 is viewed from the front side. The front-rear direction is an example of a "first direction," and the left-right direction is an example of a "second direction." However, the relationship between the front, back, left, right, top, and bottom, the first direction, and the second direction is relative, and is not limited to the above example.

The piping fixture 1 is for fixing piping to a wall surface. Note that the term "wall surface" refers not only to side walls, but also to any surface that defines a space, such as a floor surface and a ceiling surface. Moreover, "piping" is a tubular member through which liquid (for example, cold water, hot water) or gas (for example, air, gas) passes.

As shown in FIGS. 1 to 3, the piping fixture 1 mainly includes a base plate 10, a belt 20, a fixing piece 30, and a guide piece 40. The piping fixture 1 is integrally molded, for example, by injection molding a resin material. Examples of the resin material constituting the piping fixture 1 include polypropylene (PP), polyamide (PA), polyvinyl chloride (PVC), and the like.

The base plate 10 is a member located between the wall surface and the piping. The base plate 10 according to the present embodiment has a rounded rectangular shape with chamfered vertices when viewed from above. More specifically, the base plate 10 is a rectangle whose length in the front-rear direction is longer than in the left-right direction. Further, the base plate 10 has a flat shape in which the thickness in the up-down direction is thinner than in the front-rear direction and the left-right direction. The base plate 10 has through holes 11 , 12 , 13 , piping marks 14 a , 14 b , 15 a , 15 b , bolt hole marks 16 , 17 , 18 , and an inclined surface 19 .

The through holes 11, 12, and 13 penetrate the base plate 10 in the thickness direction. Further, the through holes 11, 12, and 13 are formed at predetermined intervals in the front-back direction. Bolts 51, 52, 53 (see FIGS. 5(B) and 6(B)) for fixing the piping fixture 1 to the wall surface are inserted into the through holes 11, 12, and 13.

The through hole 11 (first through hole) is arranged rearward from the base end portion of the belt 20 (that is, the connection portion with the base plate 10). The through hole 12 (second through hole) is arranged forward of the base end of the belt 20. That is, the through holes 11 and 12 are arranged on opposite sides of the base end of the belt 20. The through hole 13 (third through hole) is arranged in front of the through hole 12. That is, the through hole 13 is arranged at a position farther from the base end of the belt 20 than the through hole 12 is.

The pipe marks 14a and 14b (first marks) are marks indicating the center position of the small diameter pipe _P1 (see FIG. 5(B)) held by the pipe fixture 1. The piping marks 14a and 14b are provided separately on the left and right side surfaces of the base plate 10 at the same position in the front-rear direction. More specifically, the pipe marks 14a and 14b are arranged on an imaginary line parallel to the extending direction (that is, the left-right direction) of the small-diameter pipe P1 held by the pipe fixture ₁ . However, one of the piping marks 14a and 14b can be omitted.

The pipe marks 15a and 15b (second marks) are marks indicating the center position of the large diameter pipe _P2 (see FIG. 6(B)) held by the pipe fixture 1. The piping marks 15a and 15b are provided separately on the left and right side surfaces of the base plate 10 at the same position in the front-rear direction. More specifically, the pipe marks 15a and 15b are arranged on an imaginary line parallel to the extending direction (that is, the left-right direction) of the large-diameter pipe _P2 held by the pipe fixture 1. However, one of the piping marks 15a and 15b can be omitted.

The piping marks 14a, 14b, 15a, and 15b are provided apart from each other in the front-rear direction. More specifically, the piping marks 15a and 15b are arranged in front of the piping marks 14a and 14b. Further, the piping marks 14a, 14b, 15a, and 15b are protrusions that protrude outward (that is, in the left-right direction) from the side surface of the base plate 10. Further, the piping marks 14a, 14b, 15a, and 15b have an arcuate outer shape when viewed from above.

However, the shape of the piping marks 14a, 14b, 15a, and 15b is not limited to an arc shape, and may be any shape, such as a square or a triangle, as long as it is a protrusion that can be visually recognized when looking at the piping fixture 1 from above. good. Further, the piping marks 14a, 14b, 15a, 15b are not limited to protrusions, but may include grooves provided on the side surface of the base plate 10, designs printed on the side surface of the base plate 10, stickers affixed to the side surface of the base plate 10, etc. Any form that allows the operator to visually confirm the position may be used.

Furthermore, the piping marks 15a, 15b are larger than the piping marks 14a, 14b. More specifically, when the piping fixture 1 is viewed from above, the projected area of the piping marks 15a and 15b is larger than that of the piping marks 14a and 14b. However, the method for distinguishing the piping marks 14a, 14b from the piping marks 15a, 15b is not limited to making them different in size (projected area), but may be made in different colors, shapes, etc.

Bolt hole marks 16, 17, and 18 are marks that indicate the positions of bolt holes (prepared holes) that receive bolts 51, 52, and 53 inserted into through holes 11, 12, and 13. The bolt hole marks 16, 17, and 18 are provided on the left side surface of the base plate 10 so as to be spaced apart in the front-rear direction. However, the bolt hole marks 16, 17, and 18 may be provided on the right side surface of the base plate 10, or may be provided on each of the left and right side surfaces of the base plate 10.

As shown in FIG. 4, bolt hole marks 16, 17, 18 are formed at the intersections of virtual lines l1, l2, l3 passing through the through holes 11, 12, 13 and extending in the left-right direction and the left side surface of the base plate 10. has been done. Further, the bolt hole marks 16, 17, and 18 protrude outward (more specifically, to the left) from the left side surface of the base plate 10. Further, the center portions of the tips of the bolt hole marks 16, 17, and 18 are gouged out in an arc shape along the outer edge of the bolt hole formed in the wall surface.

However, the shapes of the bolt hole marks 16, 17, and 18 are not limited to the above-mentioned example, and may be any shape as long as the position where the bolt hole should be formed can be visually recognized when looking at the piping fixture 1 from above. . Further, the bolt hole marks 16, 17, and 18 are not limited to protrusions, but may include grooves provided on the side surface of the base plate 10, designs printed on the side surface of the base plate 10, stickers affixed on the side surface of the base plate 10, etc. It may be in any form that allows a person to visually recognize the location.

The inclined surface 19 is provided at the front end of the upper surface of the base plate 10. The inclined surface 19 is a surface that slopes downward toward the front end of the base plate 10. The inclined surface 19 plays the role of guiding the piping entering the inside of the belt 20 together with a guide piece 40 which will be described later.

The belt 20 is a band-shaped portion that is wound around the pipe, and has an arcuate outer shape. Further, the belt 20 is configured to be elastically deformable into a shape along the piping. The belt 20 has a predetermined width in the left-right direction (approximately the same width as the width of the base plate 10 in the left-right direction). Further, the belt 20 is curved in an arc shape on a plane including the up-down direction and the front-back direction (in other words, a plane perpendicular to the left-right direction).

More specifically, the belt 20 protrudes from the upper surface of the base plate 10 between the through holes 11 and 12 in the front-rear direction. Further, the belt 20 is inclined and protrudes rearward and upward (that is, toward the through hole 11 side). Further, the belt 20 extends forward (ie, toward the through holes 12 and 13 side) while being curved. The tip of the belt 20 is a free end.

Furthermore, as shown in FIGS. 2 and 3, the belt 20 has a protrusion 21. The protrusion 21 protrudes toward the inside of the curve of the belt 20 at the distal end of the belt 20 and extends in the left-right direction. This protrusion 21 serves to guide the pipe entering the inside of the belt 20 and to prevent the pipe from jumping out from the inside of the belt 20.

The fixing piece 30 is provided at the tip of the belt 20. The fixed piece 30 has a generally flat outer shape. When the belt 20 is in its natural state (no external force other than gravity is applied), the fixing piece 30 extends forward and upward from the tip of the belt 20 . On the other hand, as shown in FIGS. 5(B) and 6(B), when the belt 20 is wound around the pipe, the fixing piece 30 comes into surface contact with the upper surface of the base plate 10.

Furthermore, the fixing piece 30 is formed with a through hole 31 (fixing through hole) that penetrates in the thickness direction. The through hole 31 is formed at a position where it can communicate with one of the through holes 12 and 13 by elastically deforming the belt 20 (more specifically, by winding the belt 20 around a pipe).

The guide piece 40 is provided at the tip of the fixed piece 30. The fixing piece 30 has a tapered shape that gradually becomes thinner toward the tip. Further, the guide piece 40 extends forward and upward from the tip of the fixed piece 30. That is, the distance between the upper surface of the base plate 10 and the lower surface of the guide piece 40 gradually widens toward the front (that is, toward the tip of the guide piece 40).

Next, with reference to FIG. 5, a procedure for fixing the small-diameter pipe P ₁ (first pipe) to the wall surface G using the pipe fixture 1 will be described. FIG. 5 is a diagram illustrating the procedure for fixing the small-diameter pipe P1 to the wall G using the pipe fixture ₁ , in which (A) shows the state in which the pipe fixture 1 is positioned, and (B) shows the small-diameter pipe P1. ₁ shows a state in which the belt 20 is wound.

First, as shown in FIG. 5(A), an operator irradiates the wall surface G with a linear laser beam L that indicates the position where the small diameter pipe _P1 is to be installed. Next, the operator installs the piping fixture 1 on the wall surface G so that the piping marks 14a and 14b overlap with the laser beam L. Thereby, the position of the piping fixture 1 in the first direction is determined. Then, the operator draws marks M ₁ and M ₂ along the gouged parts of the bolt hole marks 16 and 17 with a pen or the like.

Next, the operator removes the piping fixture 1 from the wall surface G and forms bolt holes at the positions of the marks M ₁ and M ₂ using a drill or the like. Next, the operator installs the piping fixture 1 on the wall surface G so that the through holes 11 and 12 overlap the bolt holes formed at the positions of marks M ₁ and M ₂ . Thereby, the installation position of the piping fixture 1 is determined. Note that instead of drawing the marks M ₁ and M ₂ , the operator may directly form the bolt holes along the gouged parts of the bolt hole marks 16 and 17 .

Next, the operator inserts the bolt 51 into the through hole 11 and screws the bolt 51 into the bolt hole that overlaps with the through hole 11 . Next, as shown in FIG. 5(B), the operator causes the pipe fixture 1 fixed to the wall surface G to hold the small diameter pipe _P1 . More specifically, the operator inserts the small diameter pipe P ₁ in the first direction from between the inclined surface 19 and the guide piece 40 toward the inside of the belt 20 . Next, the operator elastically deforms the belt 20 to make the through holes 12 and 31 communicate with each other, inserts the bolt 52 into the connected through holes 12 and 31, and screws the bolt 52 into the bolt hole that overlaps with the through hole 12. Match.

Note that the operator performs the above-mentioned work at a plurality of positions spaced apart in the direction in which the small-diameter pipe _P1 extends. Thereby, the small-diameter pipe P1 is fixed to the wall surface G by the plurality of pipe fixtures ₁ spaced apart in the second direction.

Next, with reference to FIG. 6, a procedure for fixing the large-diameter pipe P ₂ (second pipe) to the wall surface G using the pipe fixture 1 will be described. FIG. 6 is a diagram illustrating the procedure for fixing the large-diameter pipe _P2 to the wall surface G using the pipe fixture 1, in which (A) shows the state in which the pipe fixture 1 is positioned, and (B) shows the large-diameter pipe P2. A state in which the belt 20 is wound around the pipe _P2 is shown. Note that the explanation of the parts common to the procedure for fixing the small diameter pipe _P1 will be omitted, and the explanation will focus on the differences.

First, as shown in FIG. 6(A), an operator installs the piping fixture 1 on the wall surface G so that the piping marks 15a and 15b overlap with the laser beam L. Next, the operator draws marks M ₁ and M ₃ along the gouged parts of the bolt hole marks 16 and 18 with a pen or the like. Next, the operator forms bolt holes at the positions of marks M ₁ and M ₃ using a drill or the like. Then, the operator installs the piping fixture 1 on the wall surface G so that the through holes 11 and 13 overlap the bolt holes formed at the positions of the marks M ₁ and M ₃ .

Next, the operator inserts the bolt 51 into the through hole 11 and screws the bolt 51 into the bolt hole that overlaps with the through hole 11 . Next, as shown in FIG. 6(B), the operator causes the pipe fixture 1 fixed to the wall surface G to hold the large diameter pipe _P2 . Next, the worker elastically deforms the belt 20 to make the through holes 13 and 31 communicate with each other, inserts the bolt 53 into the communicated through holes 13 and 31, and screws the bolt 53 into the bolt hole that overlaps with the through hole 13. Match.

According to the above embodiment, for example, the following effects are achieved.

According to the above embodiment, the piping fixture 1 can be installed easily and accurately by simply performing the work according to the above procedure based on each of the marks 14a, 14b, 15a, 15b, 16, 17, and 18. can. As a result, the work of laying piping on the wall surface G can be performed efficiently.

Furthermore, according to the embodiment described above, since the piping marks 14a, 14b, 15a, and 15b are made to protrude from the side surface of the base plate 10, visibility when the piping fixture 1 is viewed from above is improved. As a result, the installation work of the piping fixture 1 becomes even easier. The same applies to the bolt hole marks 16, 17, and 18.

Further, the pipe fixture 1 according to the above embodiment can selectively hold two types of pipes P ₁ and P ₂ having different diameters. By employing such a configuration, it is difficult for the operator to grasp where in the pipe fixture 1 the center positions of the pipes P ₁ and P ₂ pass. Therefore, by providing the respective marks 14a, 14b, 15a, 15b, 16, 17, and 18 as in the above embodiment, it is possible to suppress the decrease in work efficiency. However, the number of variations in the diameter of the pipes that the pipe fixture 1 can hold is not limited to two, and may be one, three or more.

Further, according to the above embodiment, by making the sizes of the pipe marks 14a, 14b and the pipe marks 15a, 15b different in correspondence with the diameters of the pipes _P1 , _P2 , which pipe mark can be Workers can intuitively understand whether to overlap the laser beam.

Further, according to the above embodiment, by devising the shape of the belt 20, the pipes P ₁ and P ₂ having different diameters can be appropriately held.

Furthermore, according to the embodiment described above, by providing the inclined surface 19 and the guide piece 40, the pipes P ₁ and P ₂ can be smoothly entered inside the belt 20.

Note that the procedure for fixing the pipes P ₁ and P ₂ to the wall surface G with the pipe fixture 1 is not limited to the above-mentioned example, and can be changed without departing from the gist of the present invention. For example, the belt 20 may hold the pipes P ₁ and P ₂ before the pipe fixture 1 is fixed to the wall surface G with the bolt 51 inserted into the through hole 11.
