Description

  The present invention relates to a pipe fixture for fixing a pipe arranged in an underfloor region surrounded by a rising portion of a foundation.

  Under the floor of the building, water supply pipes and drainage pipes are arranged. These pipes are fixed to the ground or the like on the cloth foundation or the bottom plate portion of the solid foundation. For the cloth foundation, for example, a stainless steel wire bent into a U shape is used. The U-shaped stainless steel wire is fixed to the ground by inserting the U-shaped stainless steel wire into the ground so as to sandwich the pipe disposed on the cloth foundation. In addition, when fixing a pipe to a solid foundation, for example, a jig made by bending a stainless steel strip into a substantially U shape is used, and the pipe is fitted with the jig, and this is fixed with concrete pins or screws. Secure to the bottom plate of the solid foundation. In this way, as a jig for fixing the pipe, a dedicated jig corresponding to the pipe diameter of the pipe may be used, or a jig having an adjuster function may be used.

  As a jig for fixing to a solid foundation, for example, Patent Document 1 discloses a configuration in which the above U-shaped band plate jig is applied.

JP 2005-155247 A

  However, the above U-shaped jig made of stainless steel wire has only a problem of being easily pulled out from the ground because it is only inserted into the ground. In addition, since the construction worker is often made by bending a stainless steel wire at the site or the like, it takes time and labor when a large number of construction workers are required. On the other hand, when the above U-shaped jig made of stainless steel strip is used, concrete pins and screws are required, and the number of necessary parts increases, making these preparations and construction work complicated.

  In addition, when constructing pipes with different pipe diameters using the above U-shaped jig made of stainless steel strip, a U-shaped jig of a size that matches the pipe of each pipe diameter is required. Preparation takes time and preparation of jigs of various sizes in advance is expensive. Furthermore, it is troublesome to select a desired U-shaped jig at the construction site, and it takes time and effort to select it. Further, when a jig having an adjuster function is used, the cost increases as compared with the U-shaped jig described above. Furthermore, a jig having an adjuster function cannot be easily loosened once the pipe is set and fastened, and it takes time for retightening and position adjustment.

  Then, an object of this invention is to provide the pipe fixing tool which can improve the workability | operativity required for a preparation and construction work.

  The present invention is a pipe fixture for fixing a pipe arranged in an underfloor region surrounded by a rising part of a foundation, and is provided so as to protrude downward from a main body part and a lower part of the main body part. An anchor portion and a pipe holding portion that is provided in the main body portion and holds the pipe, and the anchor portion is applied with a downward load to the main body portion so that the anchor portion is the ground or foundation of the underfloor region. It is the pipe fixture characterized by becoming the state embedded in the bottom plate part.

  In such a configuration, by applying a load downward to the main body portion, the anchor portion is embedded in the ground of the fabric foundation or the bottom plate portion of the solid base, and the main body portion and the tube holding portion are desired in the underfloor region. Positioned in place. Therefore, according to the pipe fixture of this structure, since it can install easily in the desired position of an underfloor area | region, the effort which construction work requires can be reduced. Moreover, it is not necessary to perform bending work at the construction site unlike the above-described configuration in which the conventional stainless steel wire is bent and made by itself. Furthermore, since the U-shaped jig of the conventional stainless steel strip described above does not require the necessary concrete screws, pins, etc., it is possible to reduce the number of articles and tools required for the construction work, Costs can be reduced and labor and time required for construction work can be reduced, thereby improving workability.

  Further, a hitting surface to be hit by a hitting tool is formed at the upper end of the main body, and the hitting surface is disposed on the axis of the anchor part, and the hitting of the main body by the hitting tool. A configuration is proposed in which the anchor portion is embedded by hitting the surface and applying a downward load.

  By adopting such a configuration, it is possible to construct with only a striking tool that is relatively easy to prepare, and therefore it is possible to effectively reduce labor and time required for construction work.

  The tube holding portion is formed by an annular elastic strip portion having one end connected to the main body portion and the other end being a free end, and the pipe to be held elastically deforms the elastic strip portion. A configuration is proposed in which the elastic band piece is inserted by being inserted into the ring and held by the restoring force of the elastic band piece.

  With such a configuration, the pipe can be easily attached and the pipe can be firmly fixed by the elastic deformation of the pipe holding portion formed of the elastic band piece. Further, since the work of removing the once-attached pipe can be performed relatively easily, work such as position adjustment is simple. Furthermore, since the structure of the pipe holding portion for holding the pipe is extremely simple, there is an advantage that the number of parts is small.

  Further, in the configuration in which the anchor portion is embedded in the ground of the underfloor region, the anchor portion includes a main trunk portion having a sharp lower end portion that extends downward from the main body portion, and the main trunk portion. A configuration is proposed that includes an elastic protruding portion that protrudes upward and is elastic and has a protruding shape.

  In such a configuration, when embedding in the ground of the fabric foundation, the retaining elastic protrusion is elastically deformed toward the main trunk side, so that there is little resistance to the ground and can be embedded easily. Furthermore, even if a force is applied in the direction of pulling out from the ground in the installation state embedded in the ground, the retaining elastic protrusion is elastically deformed to the opposite side and resistance is generated, so that it can be easily pulled out. Absent. Therefore, there is an advantage that the installation state embedded in the ground can be maintained for a long time.

  Further, in the configuration in which the anchor portion is embedded in the ground of the underfloor region, the anchor portion includes a main trunk portion having a sharp lower end portion that extends downward from the main body portion, and the main trunk portion. A configuration is proposed that includes a plate-shaped retaining plate portion that is extended outward and is inflexible and has a lateral width that decreases as it goes downward.

  In such a configuration, since the retaining plate portion has a shape in which the lateral width is reduced downward, it can be embedded relatively easily when embedded in the ground of the fabric foundation. Moreover, even if a force acts in the direction of pulling out while being embedded in the ground of the fabric foundation, the retaining plate portion is not easily pulled out due to resistance. Moreover, in the installation state embed | buried under the ground, there exists an advantage that it is hard to rotate around the axis line of a main trunk part because a retaining plate part becomes resistance.

  Further, in the configuration in which the anchor portion is embedded in the ground of the underfloor region, the anchor portion includes a main trunk portion having a sharp lower end portion that extends downward from the main body portion, and the main trunk portion. An elastic protruding part that protrudes upward and is elastic and has a protruding shape, and a plate-shaped retaining plate that protrudes outward from the main trunk part and is non-flexible and decreases in width as it goes downward The retaining elastic projection and the retaining plate are arranged at different positions along the axial direction of the main trunk, and the projecting direction of the retaining elastic projection and the A configuration is proposed in which the direction in which the retaining plate portion is inserted is different in the radial direction of the main trunk portion.

  With such a configuration, the above-described construction work easy effect and pull-out prevention effect by the pull-out elastic piece portion are exhibited, and the above-mentioned pull-out prevention effect and rotation prevention effect by the retaining plate portion are exhibited. Therefore, the installed piping can be stably held for a long time.

  In addition, a configuration in which at least one of the main body portion, the anchor portion, and the tube holding portion is made of a plastic material is proposed.

  In such a configuration, since the tube fixture becomes light, the transfer work to the construction site is facilitated, and the construction work is also facilitated.

  The pipe fixture of the present invention can be easily installed at a desired position in the underfloor region, and has an effect of reducing labor required for construction work. In addition, the number of articles and tools required for the construction work can be reduced, the labor and cost for these preparations can be reduced, the labor and time required for the construction work can be reduced, and the workability can be greatly improved. is there.

It is a front view of the pipe fixture concerning the modification in Example 1. FIG.

  The embodiment concerning the present invention is described in detail according to Examples 1-4. In addition, the pipe fixing tool of each Example 1-4 fixes piping for water supply, hot water supply, or drainage.

[Example 1]
The pipe fixture 1 of Example 1 is for fixing piping to the area under the floor surrounded by the rising part of the solid solid foundation, and as shown in FIGS. And tube holding portions 4 and 4. Here, in the present Example 1, the main-body part 2, the anchor part 3, and the pipe | tube holding parts 4 and 4 are comprised with the plastic material, and, specifically, polypropylene (PP) is employ | adopted.

  The main body 2 has a substantially inverted triangular shape in a front view having a predetermined thickness in the front-rear direction, and its upper surface is a hit surface 11 having a substantially horizontal plane. Further, arc-shaped curved concave surfaces 12 and 12 are formed on the left and right side surfaces of the main body 2. As will be described in detail later, the hit surface 11 is a surface hit by a hitting tool such as a hammer. Therefore, in order to ensure sufficient strength, the hitting surface 11 may be formed by providing a thick convex step on the top of the main body 2.

  The anchor portion 3 has a short narrow rod shape projecting downward from the lower end of the main body portion 2 and is formed along an axis L in the vertical direction perpendicular to the substantially center position of the hit surface 11. Has been. That is, the hit surface 11 of the main body 2 is disposed on the axis L of the anchor 3.

  The tube holding portions 4 and 4 extend from the upper left and right ends of the main body portion 2 along the hit surface 11 and are annularly bent so as to be folded back to the main body portion 2 side. It is constituted by an elastic band piece. Here, one end of the elastic strip portion constituting the tube holding portion 4 is continuous with the main body portion 2 and the other end is a free end, and the strip end portion 16 which is the free end. Is close to the curved concave surface 12 of the main body 2. And the pipe | tube holding | maintenance part 16 is spaced apart from the curved concave surface 12 of the main-body part 2 by elastically deforming the pipe | tube holding | maintenance part 4 of this structure in the direction which makes the curvature relatively small, and this pipe | tube holding | maintenance part 4 Can be expanded. On the other hand, when the force required for this elastic deformation is released, the curved concave surface 12 and the tube holding portion 4 are continuous without a step, and therefore the strip end portion 16 is restored by the restoring force of the tube holding portion 4. The tube holding portion 4 is reduced in diameter while sliding on the curved concave surface 12, and the band tip 16 is easily returned to the original position close to the curved concave surface 12. The elastic force of the tube holding portion (elastic band piece portion) 4 is realized by adopting a plastic material (polypropylene).

  Since the pipe fixture 1 described so far includes the pair of pipe holding portions 4 and 4 on both the left and right sides, it can be suitably used in a place where two pipes are arranged in parallel. The construction procedure will be described below.

  First, as shown in FIG. 3, a preliminary hole is drilled with a predetermined tool in the bottom plate portion T as an underfloor region made of a solid solid foundation, and the lower portion of the anchor portion 3 is press-fitted into the preliminary hole, The anchor portion 3 is embedded in the bottom plate portion T of the solid foundation by hitting the hit surface 11 with a hammer or the like. As a result, the tube fixture 1 is fixed to the bottom plate portion T of the solid foundation, and the main body portion 2 and the tube holding portions 4 and 4 of the tube fixture 1 are installed on the bottom plate portion T.

  And each pipe | tube holding part 4 and 4 of the pipe fixture 1 fixed to the baseplate part T of a solid foundation is elastically deformed, and the said strip piece front-end | tip parts 16 and 16 are spaced apart from the curved concave surfaces 12 and 12 of the said main-body part 2. FIG. Let Further, the pipe P having a circular cross section is inserted into the annular ring of the tube holding portions 4 and 4 through a gap generated by the separation between the strip tip portions 16 and 16 and the curved concave surfaces 12 and 12. Further, the force that elastically deforms the tube holding portions 4, 4 is released, and the pipe holding portions 4, 4 are gripped by the restoring force of the tube holding portions 4, 4.

  Here, the pipe P is held by the pipe holding portions 4, 4, and the outer peripheral surface of the pipe P is a curved surface inside the pipe holding portion 4 and a curved concave surface 12 of the main body portion 2. Are in surface contact. Therefore, the pipe holding portion 4 can reliably hold and fix the pipe P, and can stably hold the pipe P for a relatively long period of time.

  On the other hand, the pipe P held by the pipe holding part 4 can be easily detached by elastically deforming the pipe holding part 4. Thereby, the position adjustment work of the pipe P held by the pipe holding part 4 is facilitated.

  By the way, since the said pipe fixing tool 1 is the structure which hold | maintains the piping P using the elasticity of the said pipe holding part 4, even if this piping P with a somewhat different outer diameter is employ | adopted, it can respond to this. it can. Specifically, if the outer diameter of the pipe P is larger than the minimum inner peripheral diameter of the pipe holding portion 4 and smaller than the maximum inner peripheral diameter that becomes the elastic limit of the pipe holding portion 4, It can be suitably held and fixed. Therefore, it is not necessary to prepare a plurality of jigs according to the outer diameter of the pipe P to be used, and the burden of preparation work and transport work is reduced.

[Example 2]
The pipe fixture 21 according to the second embodiment fixes a pipe on the ground of a cloth foundation which is an underfloor region, and as shown in FIGS. 4 and 5, a plastic main body 2 and a pipe holder 4. , 4 and the anchor portion 23. In addition, since the structure of the present Example 2 is the structure similar to Example 1 except the anchor part 23, the same code | symbol is described to the same component and the description is abbreviate | omitted suitably.

  The anchor portion 23 includes a long main trunk portion 24 that extends downward from the lower end of the main body portion 2 and a plurality of retaining elastic protrusion portions 26 that protrude upward from the main trunk portion 24. ing. Here, the main trunk portion 24 is formed along an axis L in the vertical direction perpendicular to the approximate center position of the hit surface 11 of the main body portion 2 and includes a sharp lower end portion 25. Further, the retaining elastic protrusion 26 has a shape projecting obliquely upward from the main trunk 24 and is elastically deformable in an inner direction toward the main trunk 24 and an outer direction opposite to the main trunk 24.

  More specifically, in the main trunk portion 24, the retaining elastic protrusions 26 are formed two each in the vertical direction along the axis L direction. The pair of retaining elastic protrusions 26 and 26 arranged at the same height position are arranged approximately 180 degrees apart from each other around the axis L of the main trunk 24, and further arranged at the upper position. The two retaining elastic protrusions 26 and 26 and the two retaining elastic protrusions 26 and 26 arranged at the lower position are radially provided so as to be substantially equally spaced from each other in the circumferential direction. Yes.

  The pipe fixture 21 having such a configuration is fixed by burying the anchor portion 23 in the ground of the fabric foundation by hitting the hit surface 11 with a hammer or the like. At this time, since the retaining elastic projection 26 in the anchor portion 23 is elastically deformed toward the main trunk 24, the resistance received by the retaining elastic projection 26 from the ground can be made as small as possible. Therefore, the anchor portion 23 can be embedded in the ground relatively easily.

  On the other hand, when a force is applied to the pipe fixture 21 in the direction of pulling out from the ground of the cloth foundation, the main elastic part 24 of the anchor part 23 is urged upward, and each elastic elastic protrusion The portion 26 is elastically deformed in the outward direction, thereby preventing the ground from being easily pulled out due to resistance against the ground. In particular, since the plurality of retaining elastic projections 26 are radially formed with no deviation from the main trunk portion 24, the structure is more difficult to remove. Therefore, when the pipe fixture 21 is installed on the ground of the fabric foundation, it is not easily pulled out, the initial installation state is maintained, and the pipe P can be stably held for a long time.

  The configuration of the second embodiment described above is a configuration in which two retaining elastic protrusions 26 spaced apart by 180 degrees in the circumferential direction are provided so as to be radially upward and downward, but is not limited thereto, and the retaining elastic protrusions are not limited thereto. It is possible to change the arrangement position of 26 appropriately. For example, it is possible to adopt a configuration in which three retaining elastic protrusions 26 are provided around the main trunk 24 so as to be separated from each other by 120 degrees in the circumferential direction. By arranging the elastic protrusions 26 so as to be evenly removed around the main trunk portion 24 as in this configuration, resistance is evenly generated around the main trunk portion 24 at the time of embedding or pulling out.

  The configuration of the second embodiment is a configuration in which the hitting surface 11 is formed on the main body 2 and used by striking with a hitting tool. A configuration may be employed in which a load is applied and embedded.

Example 3
The pipe fixing tool 31 according to the third embodiment is for fixing a pipe on the ground of the cloth foundation in the underfloor region, and as shown in FIGS. 6 and 7, as shown in FIGS. , 4 and the anchor portion 33. In addition, since the structure of the present Example 3 is the same as that of Example 1, 2 except the anchor part 33, the same code | symbol is described to the same component and the description is abbreviate | omitted suitably.

  The anchor portion 33 includes a long main trunk portion 34 having a sharp lower end portion 35, and further includes a plurality of retaining plate portions 36 that are extended outward from the main trunk portion 34. Here, the retaining plate part 36 is formed in a plate shape of a substantially right triangle or an obtuse angle, and is closer to the main part 34 as the hypotenuse facing the right angle or the obtuse angle goes downward. That is, the size and shape of the retaining plate portion 36 are determined so that the lateral width (the length in the direction perpendicular to the axis L) gradually decreases as it goes downward. The retaining plate portion 36 is dimensioned to have substantially the same thickness as the outer diameter of the main trunk portion 34, and is made inflexible.

  In addition, two retaining plate portions 36 are arranged at two positions in the main trunk portion 34 along the axis L direction. The pair of retaining plate portions 36, 36 arranged at the same height position are arranged approximately 180 degrees apart from each other around the axis L of the main trunk portion 34, and are further arranged at the upper position. The individual retaining plate portions 36 and 36 and the two retaining plate portions 36 and 36 disposed at the lower position are provided radially so as to be substantially equally spaced from each other in the circumferential direction.

  The pipe fixture 31 having such a configuration is installed with the anchor portion 33 embedded in the ground of the cloth foundation. Here, since the anchor portion 33 has the width of the retaining plate portion 36 gradually narrowing downward, the resistance generated by the retaining plate portion 36 when it is embedded in the ground is suppressed as much as possible. Therefore, the anchor portion 33 can be embedded in the ground relatively easily. Further, in the installed state embedded in the ground, even when a force is applied in the rotation direction with the main trunk 34 as the central axis, the plate surface of the retaining plate 36 becomes a resistance to the ground. There is an advantage that the tube fixture 31 is difficult to rotate. In particular, since the plurality of retaining plate portions 36 are radially formed with no deviation from the main trunk portion 34, the retaining plate portion 36 has a structure that is more difficult to rotate.

  On the other hand, when a force in the pulling direction is applied to the tube fixing member 31 in the above-described installation state, the upper side portion of the retaining plate portion 36 becomes a resistance against the ground, so that it can be prevented from being pulled out. Therefore, the pipe fixing tool 31 is prevented from rotating in the installed state installed on the ground of the fabric foundation, and is easily prevented from being pulled out, and the pipe P is stably held for a long time. can do.

  Similarly, even in the configuration of the third embodiment, the arrangement position of the retaining plate portion 36 can be appropriately changed. In addition, by arranging the retaining plate portion 36 evenly around the main trunk portion 34, resistance is evenly generated around the main trunk portion 34 at the time of embedding or pulling out.

  In addition, the configuration of Example 3 is a configuration in which the hitting surface 11 is formed on the main body 2 and used by hitting with a hitting tool. However, an operator does not use the hitting tool and hands downward toward the main body 2. A configuration may be employed in which a load is applied and embedded.

Example 4
A pipe fixture 41 according to the fourth embodiment is for fixing a pipe on the ground of a cloth foundation in an underfloor region. As shown in FIGS. 8 and 9, a plastic main body 2 and a pipe holding section 4 are used. , 4 and an anchor portion 43. In addition, since the structure of the present Example 4 is the structure similar to Examples 1-3 except the said anchor part 43, the same code | symbol is described to the same component and the description is abbreviate | omitted suitably.

  The anchor portion 43 includes an elongated main trunk portion 44 having a sharp lower end 45, and further includes a plurality of retaining plate portions 46 that are extended outward from the main trunk portion 44, and the main trunk portion. And a plurality of retaining elastic protrusions 56 protruding upward from 44. Here, the retaining plate portion 46 has the same shape as the retaining plate portion 36 of the third embodiment described above, and the retaining elastic projection portion 56 is identical to the retaining elastic projection portion 26 of the second embodiment described above. It is the same shape.

  Further, the retaining plate portion 46 is formed at two positions that are separated from each other by approximately 180 degrees in the circumferential direction at the upper position of the main trunk portion 44, and the retaining elastic projection portion 56 is formed of the main trunk portion. In the lower position of 44, they are formed at two locations that are approximately 180 degrees apart from each other in the circumferential direction. The two retaining plate portions 46, 46 formed on the upper side of the main trunk portion 44 and the two retaining elastic protrusions 56, 56 formed on the lower side are substantially equal to each other in the circumferential direction. They are provided in a staggered manner so as to be spaced apart.

  In this configuration, the pipe fixture 41 is installed with the anchor portion 43 embedded in the ground of the fabric foundation. Here, when the anchor portion 43 is embedded, it can be embedded relatively easily based on the shapes of the retaining plate portion 46 and the retaining elastic projection portion 56 described above.

  On the other hand, in the installation state embedded in the ground, the pipe is prevented by the rotation preventing function by the retaining plate portion 46 and the pulling preventing function by the retaining plate portion 46 and the retaining elastic protrusion 56. The installation state of the fixture 41 is stably maintained. In particular, in this configuration, since the retaining plate portions 46 and the retaining elastic projection portions 56 are alternately arranged, the soil serving as the ground between the retaining plate portions 46 and 46 or between the retaining elastic projection portions 56 is used. Is easy to become familiar with, and there is an advantage that the anchor portion 43 is difficult to come off due to its frictional resistance.

  Even in the configuration of the fourth embodiment, similarly, the arrangement positions of the retaining elastic protrusion 56 and the retaining plate portion 46 can be changed as appropriate. In addition, by arranging the retaining plate portion 46 and the retaining elastic projection 56 evenly around the main trunk portion 44, resistance is evenly generated around the main trunk portion 44 at the time of embedding or pulling out.

  Further, the configuration of Example 4 is a configuration in which the hitting surface 11 is formed on the main body 2 and used by striking with a striking tool, but the operator faces the main body 2 downward by hand without using the striking tool. A configuration may be employed in which a load is applied and embedded.

  By the way, in the structure of Examples 1-4 mentioned above, it is the structure which provided the pipe | tube holding | maintenance part 4 and 4 on the right and left both sides of the main-body part 2, However, as another structure, a pipe | tube holding | maintenance is carried out only to the left-right one side. A configuration in which the portion 4 is provided may be used. Specifically, as shown in FIG. 10, a pipe fixture 61 having a single pipe holding part 4 on either one of the left and right sides of the main body 2 is proposed.

  In addition, the tube fixtures 1, 21, 31, 41, 51 described so far are made of materials other than those described above, and have mechanical properties such as rigidity, hardness, workability, impact resistance, or bending fatigue. It can be adopted as appropriate with consideration. In particular, when the main body 2 is hit at the time of construction, a material excellent in impact resistance is preferable.

  In this invention, it is not limited to the Example mentioned above, About another structure, it can change suitably within the range of the meaning of this invention.
