Description

  The present invention relates to a pipe fixture used when laying a pipe, and a pipe fixture used when laying a pipe under a double floor.

  Conventionally, when laying flexible pipes, such as polyethylene pipes, vinyl chloride resin pipes, and composite pipes of these and flexible metals such as aluminum, pipe deflection prevention, pipe weight support, and water hammer vibration In order to prevent this, and to always exhibit a certain level of construction, the tube is fixed by a tube fixture so as not to move.

  As a method for fixing the steady rest, generally, a rubber plate or a foamed resin cushioning material is wound around a pipe and stopped with a saddle band, a U band, a U bolt or the like.

  For example, as a standard method for supporting the steadying of a pipe using a pipe fixing tool, a steadying support member made of a shape steel or the like is fixed to a base, and the pipe is attached to the steady support member with a U band or a U bolt. A method of stopping is known (for example, see Non-Patent Document 1).

  In this method, in order to fix the steady rest support member, anchor bolts or anchors are provided on a concrete base or the like, so that there is a problem that a large noise is generated during construction and it can be heard in other floors and other rooms. However, since no people lived at the time of new construction, noise during construction was not considered as a problem.

  Furthermore, in the pipe laying structure using such a pipe fixing tool, the pipe is directly fixed to the steady rest support material, and the steady rest support material is directly secured to the concrete slab, etc., so that a fluid flowing through the pipe is generated. There was a problem that the noise to be transmitted propagated through the concrete slab and the like and reverberated to other floors and other rooms.

  Furthermore, in order to arrange the steady rest support material in the underfloor space, it is necessary to fix the steady rest support material and fix the pipe to the steady rest support material in the space under the floor. In addition, the arrangement height of the pipes must be adjusted, and it is difficult to say that the workability is good.

  On the other hand, the housing life of a house is generally 50 to 100 years or more. However, the interior is often required to be drastically renovated in about 30 years due to deterioration, design deterioration, and the like. Furthermore, renovation work has recently increased rapidly, including floor plans due to changes in the resident's family structure and lifestyle, and changes to housing equipment. This is backed by the arrival of the initial housing renovation period and increased consumer interest in housing usability.

In these renovations, the quiet construction method is important as a countermeasure for the neighborhood residents. Noise prevention has been a major issue.

Features.

  The pipe fixture (Invention 2) according to claim 2 is a double floor provided on a base with a floor support comprising a base provided at the lower end of the support bolt and a floor support provided at the upper end of the support bolt. A pipe fixture used when laying a pipe in an underfloor space of the pipe, the pipe fixture being a pipe holder made of a foamed resin elastic body, and a rigid presser disposed on both upper and lower sides of the pipe holder Even the plate consists of a plate and a holding bolt that penetrates the holding plates, a pipe is arranged in the middle of the height direction of the tube holding material, a through hole is provided between the holding plates, and the holding bolt is inserted, The holding bolts are tightened so that the holding plates hold the tube holding material, the tube holding material holds the tube, and the support bolt of the floor support is inserted into the fixing through hole provided in the holding plate, and the holding plate Is fixed to the support bolt, and the pipe fixture is connected and fixed to the floor support. To.

  The invention according to claim 3 (invention 3) is the foamed resin elasticity of the portion where the deformation and resilience of the foamed resin elastic body in the portion contacting the tube at a position higher than the tube bottom position is lower than the tube bottom position. It is a pipe fixing tool of invention 1 or 2 characterized by being larger than a body's deformation recovery nature.

  The invention according to claim 4 (invention 4) is any one of inventions 1 to 3, characterized in that the tube held by the tube holding material is held in a floating state in the space between the base and the floor. This is a tube fixture.

  When laying pipes from a water distribution header to a plurality of water-using equipment devices, a plurality of pipes are arranged close to each other immediately after coming out of the drainage header. Moreover, a pipe | tube comes to be independently piping in the location which goes to the direction of each equipment apparatus.

  In addition, concrete, asphalt, and the like are often placed on the base, and the base on which a double floor is laid is often made of wood, wood-based compression molding board, or the like. In any case, in order to fix the pipe, an anchor hole is formed in the base or base, and the article can be fixed with bolts or the like in the hole. In addition, in the case of a double floor, the floor is often supported by a floor support material that uses a bolt for adjusting the floor height as a support so that it can cope with unevenness of the foundation and the gradient of the piping.

  In the present invention, the fixed pipe is a pipe used for water supply or hot water supply, and is a pressure pipe having flexibility and elasticity. For example, a polyethylene pipe, a vinyl chloride resin pipe, a metal composite pipe such as polyethylene and aluminum, and the like can be given as examples.

  Usually, the position where the water distribution header is provided is under the floor of the house, but there are many cases where the position directly above is not the floor. In addition, the pipe header itself is rarely moved from the position where it was installed at the time of renovation. Only the pipes connected to the equipment are rearranged.

  Pipes coming out of the header are usually fixed in the vicinity of the header, supported by the steady rest, then piped to each water-use facility and equipment, and fixed for each individual pipe where necessary. Supported. When fixing immediately after the header, if each pipe is fixed with a saddle or the like, the number of fixing members is increased, and an anchor hole must be drilled in the base for each pipe fixing tool. When it is necessary to change the piping position at the time of renovation, etc., it is necessary to fix it again every time. In this case, it is necessary to drill anchor holes, etc., and noise will be generated. become.

  Invention 1 makes it easy to change the direction of piping without re-drilling holes in the base and the base even in a plurality of pipes immediately after exiting the water distribution header when it is necessary to change the position of some pipes at the time of reform. This is a tube fixture that does not generate noise during renovation. This pipe fixture should be constructed in advance in anticipation of remodeling in the future when a person is resident, such as when a new building is built, in order to prevent noise generation at that time. It is something to keep.

  This pipe fixing tool is applied to fixing a plurality of pipes immediately after leaving the water distribution header, and fixing pipes that are individually piped toward individual water-using equipment. These pipes are supported by a single steadying fixture with this pipe fixture, and then the pipe direction is swung toward the location of each equipment using water, and each pipe is required individually. It is fixed at various places

  In this pipe fixture, the pipe holding material is a block body made of an elastic body made of foamed resin having deformation resilience and rich in elasticity, and the pipe is held by the upper pipe holding material and the lower pipe holding material of the pipe. Is.

  A pipe | tube is arrange | positioned between an upper side pipe | tube holding material and a lower side pipe | tube holding material, and is hold | maintained from an up-down direction. The tube holding material holds the tube, absorbs vibration of the tube itself, and does not transmit the vibration to the floor or the base, so that it also has elasticity as a vibration buffer material. A recessed portion for receiving a tube along the outer diameter shape of the tube may be provided at a location where the tube is held. As long as it is a sufficiently flexible material and can be deformed as much as possible to hold the tube with the tube holding material itself, the groove for receiving the tube may be omitted.

  The groove for receiving the tube may be provided with a linear notch reaching the groove from the outer peripheral surface of the tube holding member. If it carries out like this, when inserting / removing a pipe | tube to the groove | channel for pipe | tube receiving, this notch can be expanded and it can carry out from there.

  Also, the flexibility of the tube holding material is that at least the lower tube holding material that supports the tube below the tube above the base is harder than the upper tube holding material that holds the tube from above the tube. Is preferred. This characteristic is that the holding plate is provided with a through hole, a holding bolt is inserted into the through hole, the holding bolt is tightened, and the holding plate holds the tube holding members together so that the tube is a tube holding member. In addition, when the holding bolt is screwed into an anchor hole provided in the base, the pipe fixture is fixed to the base and holds the pipe floating in the underfloor space. This is a necessary characteristic.

  When providing a groove for receiving a tube, the groove may be shaped and sized so that the tube inserted through the groove does not rattle during use. In other words, a polygonal shape such as a quadrangle, a hexagon, an octagon, etc., having a cross-sectional shape that is substantially the same as the outer diameter of the tube but having a width and height that are substantially the same as the outer dimensions of the tube. It doesn't matter.

  Furthermore, the height of the groove in the vertical direction of the groove may be slightly smaller than the outer diameter of the tube. In this case, when the tube holding material is sandwiched between the pressing plates to hold the tube, the tube holding material is compressed by the tube to hold the tube, so that the tube is reliably held.

  The shape of the upper or lower tube holding material is appropriately determined according to the material of the tube holding material and the outer diameter of the tube to be fixed. For example, if the material is flexible enough to hold the tube without the tube receiving groove, the thickness may be equal to or greater than the outer diameter of the tube to which the thickness is fixed, and the width is arbitrary. Further, the length may be any length as long as it can hold at least a plurality of tubes at the same time, and may be longer than that. .

  In the case of a tube holding material that does not have a groove for receiving a tube, the elastic modulus may be appropriately determined according to the situation. That is, if the elastic modulus is small, the tube can be held with a light force, but the held tube may move easily and vibration of the tube may not be reliably prevented. This is because there is a possibility that it cannot be reliably held.

  When providing the groove for receiving the tube, a rigid material may be used. However, in order not to damage the tube, a buffer material is arranged on the outer periphery of the tube and stored in the groove for receiving the tube. What is necessary is just to prevent scratches.

  In addition, since the tube holding material may partially condense or become hot depending on the temperature of the fluid to be passed through, it is necessary to have moisture resistance, heat resistance, heat retention and the like. Examples of the material having the above functions include polyethylene foam, urethane resin foam, and the like. Among them, the closed cell foam of cross-linked polyethylene is excellent in cost, heat resistance, heat retention and the like and is suitably applied.

  A pressing plate is provided on the upper surface or the lower surface of the tube holding material. The pressing plate is indispensable on the upper surface of the tube holding material, and has a function of holding the tube holding material by pressing the pressing plate against the base when fixing the pressing plate to the lower base. There may also be a rigid plate below the pipe holder. In this case, the foundation is not flat and the pipe holder was normally held when the pipe fixture was tightened with bolts. The present invention can also be suitably applied when there is a possibility that the tube may tilt.

  The holding plate is provided with a through hole, and a holding plate holding bolt is inserted into the through hole. That is, by tightening the holding bolt, the holding plate holds the tube holders and the tube is held by the tube holding material. The holding bolt has a function of fixing the tube fixing tool to the base by screwing the tip of the bolt into an anchor hole provided in the base.

  If there is no holding plate on the lower side of the tube holding material, the lower tube holding material is in direct contact with the base and the tube fixing tool is fixed to the base, but when a holding plate is also provided below the tube holding material. The nut may be screwed onto the holding bolt, and the holding plate may be held between the holding plates by fastening the holding plates with the nut and the holding bolt head.

  Accordingly, the pressing plate is preferably a band plate-like body having high bending rigidity, excellent corrosion resistance, and a planar shape covering the planar shape of the tube holder. Examples of the pressing plate include, for example, a plate made of metals such as stainless steel, anticorrosive iron, and aluminum; and fiber reinforced resins such as carbon fiber and glass fiber.

  As for the shape of the pressing plate, it is preferable that the planar shape covers the planar shape of the tube holding material, and it may be made somewhat larger. Further, the enlarged portion may be bent toward the tube holding material to hold the tube holding material. If it is a bent shape, the presser plate itself is more difficult to bend due to the rib effect at the bent portion, and the possibility that the tube holding material is detached from the presser plate is reduced.

  At least one through hole is required in the pressing plate. When the holding plate has sufficient bending rigidity, such as when the pressing plate has a rib structure as described above, sufficient fixing can be performed at one place. However, it is usually stable when provided near both ends in the length direction.

  In addition, the through hole may have the same planar dimensions as the holding plate and the pipe holding material, and may penetrate both of them. You may provide in the vicinity of the both ends which do not have material. If the tube holding material is penetrated at the same time, the tube holding material is less likely to escape from under the pressing plate when tightened.

  The method of fixing the tube fixing tool to the base may be a method of fixing using a normal bolt. For example, an anchor hole is drilled in the base and the holding bolt inserted into the through hole of the holding plate in the hole. The tip of the screw is good. Alternatively, a dimensioning bolt may be screwed into the anchor hole, and a nut may be threaded to the other end of the dimensioning bolt to stop the upper holding plate. When there is a pressing plate on the lower side, a nut that stops the lower pressing plate may be bitten and the pressing plate may be stopped with a bolt head or an upper nut.

  Invention 2 is a pipe fixture that is particularly preferably used when a pipe that is piped to an individual water-use facility or equipment after coming out of a water distribution header is steady at a place that is a double floor. .

  The pipe fixture according to the second aspect of the present invention is a floor support tool comprising a base provided at the lower end of the support bolt and a floor support provided at the upper end of the support bolt. It is a pipe fixture used when laying a pipe. In this floor support, the main body is a support bolt and the floor is placed on a floor support portion screwed into the support bolt to support the floor. Can be made.

  The tube fixture is composed of a tube holding material in which elastic bodies made of foamed resin are stacked, a belt-like pressure plate having rigidity for holding the tube holding material, and a holding bolt penetrating the pressure plates. Is done. The tube is disposed between the stacked tube holding members.

  The holding plates are provided with through holes and the holding bolts are inserted therethrough. The holding bolts are tightened so that the holding plates hold the tube holding material, and the tube holding material holds the tube. Further, the holding plate is provided with a fixing through-hole, and the support bolt of the floor support is inserted into the fixing through-hole, and the holding plate is fixed to the support bolt and the tube fixing tool is connected and fixed to the floor support. The

  The holding plate is provided with a holding through-hole through which a holding bolt for holding the holding plates is inserted so that the hole axes coincide with each other. Furthermore, a fixing through-hole through which a fixing bolt for connecting and fixing the pipe fixing tool to the supporting bolt of the floor support is inserted in at least one pressing plate.

  The tube holding material is a flexible elastic body made of a foamed resin that is easily deformed and highly elastic. The tube is disposed between the upper tube holding member and the lower tube holding member, and has a function of holding the tube by being held from above and below by a pressing plate. In this case, the pressing plates may be sandwiched strongly to such an extent that the tube holding material is deformed by the tube, or may be sandwiched lightly to such an extent that it does not deform.

  The tube holding portion may be provided with a groove for receiving the tube along the outer diameter shape of the tube, which is a sufficiently flexible material that can be deformed as much as possible to hold the tube with the tube holding material itself. If there is, there is no need for the groove for receiving the tube. In this way, the tube holding material holds the tube and absorbs vibration of the tube itself, and does not transmit the vibration to the floor or the base, so that it also has elasticity as a vibration buffer material.

  The groove for receiving the tube may be provided with a linear notch reaching the groove from the outer peripheral surface of the tube holding member. If it carries out like this, when inserting / removing a pipe | tube to the groove | channel for pipe | tube receiving, this notch can be expanded and it can carry out from there.

  In addition, the flexibility of the tube holding material is that at least the lower tube holding material that holds the tube above the base while holding the tube above the tube is above the tube and holds the tube from above. It is preferably harder than the tube holding material. This characteristic is a preferable characteristic for holding the pipe in a floating state in the under-floor space when the pipe holder is fixed to the base with an anchor bolt or the like inserted through the holding plate.

  The shape of the upper or lower tube holder differs depending on the material, but if the material is flexible enough to hold the tube without the tube receiving groove, The width is not limited as long as it is larger than the diameter. Also, the length is not limited as long as it is capable of holding at least a plurality of tubes at the same time, and may be longer than that. good.

  In the case of a tube holding material that does not have a groove for receiving a tube, the elastic modulus may be appropriately determined according to the situation. That is, if the elastic modulus is small, the tube can be held with a light force, but the held tube may move easily and vibration of the tube may not be reliably prevented. This is because there is a possibility that it cannot be reliably held.

  When providing the groove for receiving the tube, a rigid material may be used. However, in order not to damage the tube, a buffer material is arranged on the outer periphery of the tube and stored in the groove for receiving the tube. What is necessary is just to prevent scratches.

  In addition, since the tube holding material may partially condense or become hot depending on the temperature of the fluid to be passed through, it is necessary to have moisture resistance, heat resistance, heat retention and the like. Examples of the material having the above functions include polyethylene foam, urethane resin foam, and the like. Among them, the closed cell foam of cross-linked polyethylene is excellent in cost, heat resistance, heat retention and the like and is suitably applied.

  A holding plate is provided on each of the upper and lower surfaces of the tube holding member. The holding plate has a function of holding the tube holding material and a function of connecting the tube fixing tool to the floor support. For this purpose, the two holding plates are provided with holding through holes into which holding bolts for holding the holding plates are inserted, and at least one holding plate has the holding through holes. In addition, a fixing through hole is provided for fitting and fixing the pipe fixing tool to the support bolt of the floor support tool.

  Nuts are screwed onto the holding plate holding bolts, and by tightening these, the holding plates are tightened with the bolt head and nut, the tube holding material is sandwiched between the clamped holding plates, and the tube holding material holds the tube. Hold.

  Accordingly, the holding plate is preferably a belt-like body having high bending rigidity, excellent corrosion resistance, and a planar shape covering the planar shape of the tube holder. Examples of the pressing plate include, for example, a plate made of metals such as stainless steel, anticorrosive iron, and aluminum; and fiber reinforced resins such as carbon fiber and glass fiber.

  As for the shape of the pressing plate, it is preferable that the planar shape covers the planar shape of the tube holding material, and it may be made somewhat larger. The further enlarged portion may be bent in the direction of the tube holding material to hold the tube holding material. If it is a bent shape, the presser plate itself is more difficult to bend due to the rib effect at the bent portion, and the possibility that the tube holding material will be detached from the presser plate when being held is reduced.

  At least one holding through hole into which the holding plate holding bolt is inserted is required in the holding plate. When the holding plate has sufficient bending rigidity, such as when the pressing plate has a rib structure as described above, it can be sufficiently fixed at one place.

  Further, the through hole may be provided so as to penetrate the holding plate and the tube holding material, and the holding plate is lengthened so that the tube holding material is sandwiched in the middle in the length direction, and there is no tube holding material. You may provide in the vicinity of both ends. If the tube holding material is penetrated at the same time, the tube holding material is less likely to escape from under the pressing plate when tightened.

  In the invention 3, in the tube holding material of the invention 1 or 2, the flexible foamed resin elastic bodies having greater deformation and restoration properties when compressed and deformed than the tube holding material are stacked. Therefore, in any of the tube fixtures of the invention 1 or 2, when the tube holding material is strongly sandwiched between the pressing plates, even if the tube holding material receives a large deformation stress by the tube, the flexible elastic body is deformed. The deformation of the tube holding material is minimized.

  Further, when the flexible elastic bodies are stacked so as to be in contact with the pipe, the pipe can be held without providing a pipe receiving groove in the pipe holding material if the deformation of the flexible elastic body is sufficiently large.

  Moreover, invention 4 is hold | maintained with the tube holding material with which the pipe | tube was piled up, and can hold | maintain the pipe in the state which floated in the space between a base | substrate and a floor, The pipe in any one of the invention 1-3 It is also a holding material. That is, in any of the pipe fixtures of the inventions 1 to 3, since the pipe is sandwiched and arranged in the middle of the pipe holding member in the height direction and is held on the base in this state, the outer peripheral lower surface of the pipe is below the floor. It will be in a state of floating in space.

Next, a method for using the tube fixture of the present invention will be described.
For example, as a method of holding the pipe in the pipe fixing tool of the first aspect of the invention and fixing the pipe on the base, for example, first, it corresponds to a through hole provided in the holding plate at a place where the pipe fixing tool of the base is arranged. A predetermined anchor hole is drilled at the position. Next, the pipes to be piped are arranged between the stacked pipe holding members, a pressing plate is placed thereon, and holding bolts are inserted into the through holes. When the holding bolt is tightened, the holding plate sandwiches the tube holding materials, and the tube holding material holds the tube. As the tube holding material, when the holding bolt is screwed into an anchor hole provided on the base, the pipe fixing tool is pressed by the base surface and the pressing plate to be fixed to the base and the pipe is fixed.

  When using a pressure plate on the lower surface of the tube holding material, after placing the tube between the tube holding materials, stack the pressure plate on the upper and lower surfaces of the tube holding material and insert them into the through holes in the pressure plate. A holding nut is screwed under the holding plates below the holding bolts, and the holding plate is held between the nuts and the tube is held by a tube holder. When the head of the holding bolt protruding from the nut is screwed into an anchor hole provided in the base, the pipe fixing tool is fixed to the base and the pipe is fixed.

  Instead of holding bolts, insert a slitting bolt into the through hole, screw the holding nut so that the holding plate is sandwiched, screw the nuts together and sandwich the tube holder with the tube holder. It may be held and fixed by screwing into the anchor hole provided at the base of the cutting bolt.

  As a method for holding the pipe in the pipe fixing tool of the invention 2 and fixing it to the space under the floor, for example, first, the pipe to be piped is arranged between the stacked pipe holding materials, and the pipe holding material is Each holding plate is overlapped on the lower surface, and a holding nut is screwed into a holding bolt inserted through the through hole of the holding plate, and the holding plates are fastened together with the nut, and the tube is held by the tube holder. Next, the fixing plate's fixing through hole is inserted into the floor support's support bolt, the floor surface height is adjusted, and the nut that has been screwed into the support bolt is tightened. The method of fixing so that it may not be mentioned.

Furthermore, in the invention 3, a flexible foamed resin elastic body having a greater deformation and resilience than that of a portion that is lower than the tube bottom surface position is superimposed on a portion that contacts the tube at a position higher than the tube bottom surface position. The flexible tube holding material may be disposed in contact with the tube, or all of the tube holding material above the tube arrangement position may be a flexible foamed resin elastic body.

  When the flexible tube holding material is used so that it is in contact with the tube and is positioned above the tube, the flexible tube holding material itself is held when the tube holding material sandwiching the tube is sandwiched by the holding plate. Since the tube is held so as to be largely deformed, the tube can be held without providing a tube receiving groove in the tube holding material. Also, since there is no groove, it is not necessary to keep the pipe direction along the direction of the concave groove when changing the piping direction at the time of renovation, etc., so there is no restriction on the piping direction, and the direction can be changed freely. be able to.

  In invention 4, a pipe | tube is hold | maintained with the pipe | tube holding material, and the pipe | tube is hold | maintained in the state which floated in the space between a base | substrate and a floor | bed. That is, since the pipe is disposed on the lower pipe holding member, the bottom height of the pipe held by the pipe holding member is held above the base. For example, in the case where the press plate of the invention 1 is stacked on the pipe holding material, even if the pipe holding material is pressed against the base surface with a strong force by the press plate, the lower pipe holding material is used. It may be tightened so as not to be deformed until the pipe contacts with the back.

  Further, in the case where there is a pressing plate on the lower surface of the tube holding material or in the case of the fixing device of the invention 2, the tube fixing tool is fixed so that the lower pressing plate is b above the base, so that the pipe touches the base. Without being suspended in the space under the floor. Furthermore, when the upper tube holding material is deformed to a greater extent than the lower tube holding material, the upper tube holding material is greatly deformed to hold the tube even if the tube holding material is strongly tightened with the holding plate. There is little deformation of the tube holding material, and the tube is held in a floating state without touching the base.

    In any of the pipe fixtures of the inventions 1 to 4, since the holding of the pipe holding material is released only by loosening the bolt or nut, the piping fixed between the upper and lower pipe holding materials is It becomes free and the piping direction can be changed to a required direction. In particular, when the pipe receiving groove is not provided, the direction of the groove is not affected, so that the change of the pipe direction becomes completely free. After the change, the pipe is fixed only by tightening the bolt or nut again.

  In the pipe fixtures of the inventions 1 to 4, it is necessary to pierce the anchor hole once when newly installed, but at the time of renovation, it is not necessary to pierce the anchor hole, so no noise is generated, and the sound of fluid flowing in use is not generated. However, it is possible to improve the workability of the piping that does not resonate with other floors.

  Thus, regardless of which pipe fixing tool is used, the anchor hole is pierced only once at the time of new installation, and the fixing work of the pipe is only screwing of the bolt or nut, so that the workability is good. . In addition, the bolt or nut is only loosened at the time of renovation, and it is not necessary to drill a new anchor hole. Therefore, the direction of the pipe can be easily changed without noise.

  In the tube fixing device of the invention 1, the tube is disposed between the tube holding members on which the foamed resin elastic bodies are stacked, the holding bolt is inserted into the through hole provided in the holding plate, and the holding bolt is tightened. Then, the holding plate holds the tube holding members, and the tube is held by the tube holding member. If the holding bolt is screwed into the anchor hole provided in the base, the pipe fixture is fixed to the base, so the pipe needs to be fixed once, and the pipe can be connected by tightening the anchor bolt regardless of the pipe direction. Since it is fixed, it does not take work. Moreover, at the time of renovation, the direction of the piping can be changed simply by loosening the bolts or nuts, so that no noise is generated and the piping changing operation is easy.

In the second aspect of the present invention, the pipe fixture is a double-floor under floor that is affixed on a base with a floor support composed of a base provided at the lower end of the support bolt and a floor support provided at the upper end of the support bolt. Used when laying pipes in space. The tube fixture includes a tube holding material in which foamed resin elastic bodies are stacked, a holding plate for holding the tube holding material, and a holding bolt that penetrates the holding plates. The tubes are arranged between the stacked tube holding materials, and holding bolts are tightened in through holes provided between the holding plates, and the holding plates hold the tube holding materials, and the tube holding material holds the tubes. Hold.
In the pipe fixing tool, a support bolt of the floor support is inserted into a fixing through hole provided in the pressing plate, and the pipe fixing tool is connected and fixed to the floor supporting tool by fixing the pressing plate to the support bolt. Therefore, it is not necessary to pierce anchor holes for fixing pipes even when newly installing pipes. Furthermore, there is no drilling noise such as anchor holes even during renovation, and only the nuts are loosened. Since the direction of the piping can be changed, the work is easy.

  In the invention 3, a flexible foamed resin elastic body having a greater deformation and resilience than the tube holding material at a position lower than the tube bottom is overlaid at a position in contact with the tube at a position higher than the tube bottom. Therefore, the tube holding material is strongly tightened by the pressing plate, and the flexible tube holding material is compressed and deformed by the tube. Therefore, the pipe is reliably held even if the pipe holding material is not provided with a groove for receiving the pipe. Moreover, since there is no restriction | limiting by the groove for receiving a pipe also at the time of reform, the direction of piping can be changed more freely.

  Furthermore, if the upper surface of the upper tube holding member is made of a flexible elastic body, for example, the concave portion formed by the rib on the back surface of the floor panel of the double floor and the upper end portion of the tube holding member are not accurately fitted and shifted. However, since the flexible elastic body is compressed and greatly deformed by the rib, it is strongly pressed against the back surface of the floor panel, and therefore the tube holding member is securely fixed.

  In invention 4, since a pipe | tube is hold | maintained between the piled tube holding materials, a pipe | tube is hold | maintained in the state which floated in the space between a base | substrate and a floor | bed. Furthermore, if the upper tube holding material is a flexible foamed resin elastic body that has a larger amount of deformation than the lower tube holding material, the lower tube holding can be maintained even if the tube holding material is strongly sandwiched between the holding plates and deformed. The material is less deformed than the upper tube holding material, so that the tube sandwiched between the tube holding materials is fixed in a floating state in the underfloor space. Therefore, the flow down sound of the fluid flowing in the pipe in use is rarely transmitted to other floors.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an example of the tube fixing device of the invention 1, and FIG. 1A is a perspective view of an example in which a pressing plate having the same planar shape as the planar shape of the tube holding material is provided on the upper surface of the tube holding material. (A) is a perspective view of an example in which the length of the pressing plate is increased, (c) is a perspective view of an example in which the side of the pressing plate is bent downward to form a rib shape, and (d) is ( It is a perspective view of an example in which the length of the pressing plate of c) was lengthened. Although not shown, the side on the length side of the pressing plate may be bent downward to form a rib, and the entire side may be bent into a rib, or the side may be bent. Needless to say, the length of the pressed plate may be increased.

  In FIG. 1A, the tube holding material 2 includes an upper tube holding material 21 and a lower tube holding material 22. Further, a pressing plate 3 having the same planar shape as the planar shape of the tube holding material 2 is provided on the upper surface of the upper tube holding material 21.

  The pressing plate 3 may be longer than the length of the tube holding member 2 as shown in FIG. 1 (b), or may be ribbed as shown in FIG. 1 (c). good. If it is made into a rib shape, the tube holding material is fitted in the recess between the ribs, and when the holding plate is tightened, the tube holding material will not escape from the holding plate, and the bending strength of the holding plate will increase. Even if the tightening portion (for example, the opening position of the holding and tube holder fixing through-hole 41) is only one (not shown), there is an effect that secure tightening can be performed.

  In FIG. 1, the upper and lower tube positions are shown by different hatching so that the upper and lower positions of the tube can be easily understood. Even if it is a body block, the 2 or more foamed resin elastic body block may be piled up. In the case of the same foamed resin elastic body, it is only necessary that a groove for receiving the tube is provided in the middle of the height direction of the elastic body so that the pipe can be arranged. The tube holding material 21 and the lower tube holding material 22 are separated, and a plurality of tubes P1, P2,. The holding plate 3 is provided with a holding / pipe holding fixture fixing through-hole 41 into which at least one anchor bolt 61 or dimensioning bolt 62 is inserted.

  FIG. 2 is a cross-sectional view of an example of a pipe laying structure using the pipe holder 1 of the invention 1, and FIG. 2A is a cross-sectional view of an example of the invention 2 in which the pipe fixture is fixed to the base with anchor bolts. ) Is a cross-sectional view of an example of the invention 3 in which the tube fixing tool is fixed with a cutting bolt. In this example, description will be made using the tube fixture shown in FIG. 1 (a). However, the tube fixing method is the same for other shapes of the tube holder shown in FIG. I won't repeat it.

  A plurality of pipes P1, P2,... Coming out of a pipe header (not shown) and piped to each water use facility and equipment (none shown) are an upper pipe holding material 21 and a lower pipe holding. It is arranged between the material 22. The holding plate 3 is provided with a holding and tube holding fixture fixing through hole 41, and an anchor bolt 61 (FIG. 2) that is screwed into the anchor hole 5 formed in the base B to tighten the holding plate. (See (a)), or a cutting bolt 62 (see FIG. 2B) screwed into the anchor hole 5 is inserted.

  The holding plate 3 is tightened toward the base B by the anchor bolt 61 or the dimension bolt 62 inserted through the through hole 41 and the nut 7 screwed to the anchor bolt 61, and the pipe fixture 1 is fixed to the base B. . At this time, the tube holding member 2 is held by the pressing plate. Since the upper tube holding member 21 is flexible and the lower tube holding member 22 is relatively elastic compared to the upper tube holding member 21, it is sandwiched between the held tube holding members 21 and 22. The deformation amount received by the tube holding members 21 and 22 by the pipes P1, P2,... Is larger in the upper tube holding member 21 than in the lower tube holding member 22.

  Therefore, the lower tube holding member 22 is slightly depressed along the outer diameter of the tubes P1, P2,..., And the upper tube holding member 21 is greatly depressed along the tube outer diameter, and the tubes P1, P2,. The pipes P1, P2,... Are held and fixed between the pipe holding materials 21, 22 in a state where a substantially triangular cavity is formed at the contact point where the upper pipe holding material 21 and the lower pipe holding material 22 intersect. Is done.

  Since the deformation amount of the lower pipe holding member 22 is small, the fixed pipes P1, P2,... Since the lower pipe holding material 22 is also made of foamed resin, the sound of the fluid flowing through the pipes P1, P2,... And the vibration of the pipe are buffered by the lower pipe holding material 22 and are not transmitted to other floors. .

  The pipe laying procedure for making this pipe laying structure is as follows. First, in the vicinity of the pipe header, a plurality of pipes are arranged close to each other before the individual pipes are directed toward the respective water use facilities and equipment. An anchor hole 5 is drilled at the attachment position of the pipe fixture 1 of the base B at a location corresponding to the through hole 41 provided in the holding plate of the pipe fixture 1.

  Next, the lower pipe holding member 22 is put under the pipes P1, P2,... And the upper pipe holding member 21 is put thereon. Further, a pressing plate is placed thereon, and anchor bolts 61 and the like are inserted into the through holes 41 and screwed into the anchor holes 5 formed in the base B. The presser plate 3 is tightened by screwing the anchor bolt 61 or the like, the tube holding members 21 and 22 are deformed, and the tubes P1, P2,... Are fixed.

  When changing the direction of the piping at a later date, for example, the anchor bolt 61 is loosened, the holding force of the pipe holding members 21 and 22 is released and the deformation is restored, and the pipes P1, P2,. The pipe can be fixed again simply by changing the piping direction and then tightening the anchor bolt 61 or the like again. At this time, even if the pipe directions of the respective pipes are different, the pipe holding members 21 and 22 are deformed along the pipe direction of the new pipe, so there is no problem in fixing the pipe.

  FIG. 3 is an example in which a tube receiving groove 2 is provided in the tube holding material 2, (a) is a perspective view of an example in which the cross-sectional shape of the groove 23 is substantially circular, and (b) is a groove. It is a perspective view of an example whose cross-sectional shape of 23 is substantially square. In any case, a plurality of grooves 23 may be provided, and a plurality of tubes P1, P2,... May be held at the same time. Also, a circular groove and a rectangular groove 23 may be provided in combination.

  Further, as shown in FIGS. 3 (c) to 3 (e), the linear notch 24 reaches the concave groove 23 from the outer peripheral surface of the tube holding member 2 in the concave groove 23 for the pipe receiver. It may be provided. In this way, when the pipe P is inserted into and removed from the concave groove 23 for receiving the pipe, the cut 24 can be widened and performed from there.

  FIG. 4 is a cross-sectional view of an example of a pipe laying structure using the pipe holder 1 of the invention 1 in which a holding plate 32 is also provided on the lower side of the pipe holding material 2, and (a) is pressed by an anchor bolt 61. Cross-sectional view of an example in which the plates 31 and 32 are pressed and the tube holding material 2 holds the tube P and the tip of the anchor bolt 61 is fixed to the anchor hole 5 provided in the base B, (b) is one holding plate A cross section of an example in which the fixing bolt 61 is inserted into the fixing through hole 43 and the tube fixing tool 1 is fixed to the anchor hole 5 provided in the base B. FIG.

  In this case, a holding nut 72 is screwed under the lower holding plate 32, and the holding plate 2 is pressed by holding the holding plates 31 and 32 with the nut 72 and the head of the bolt 61 or an upper nut (not shown). The tube P disposed between the tube holding members 21 and 22 is held.

  FIG. 5 is an example of the tube fixing device of the invention 2, wherein (a) is a perspective view of an example in which tube holding members are stacked between two pressing plates, and (b) is a side of the upper pressing plate in (a). It is a perspective view of an example of what the side was bent below and was made into rib shape.

  The tube holding jig 1 has a shape in which the tube holding material 2 is sandwiched between two pressing plates 31 and 32. In FIG. 5A, the tube holding material 2 includes an upper tube holding material 21 and a lower tube holding material 22. Further, a pressing plate 31 having the same planar shape as that of the tube holding material 2 is provided on the upper surface of the upper tube holding material 21, and a pressing plate 32 is provided on the lower surface of the lower tube holding material 22. The lower holding plate 32 has a function of fixing the pipe fixture 1 by being connected to the support bolt 81 of the floor support 8.

  The upper pressing plate 31 may be formed in a rib shape (see FIG. 5B) by bending the side thereof downward. When the ribs are formed, the upper tube holding member 21 is fitted in the recesses between the ribs, and the upper tube holding member 21 does not escape from the holding plate when the holding plates 31 and 32 are tightened. There is an effect that the bending strength of the pressing plate 31 is increased, and even if there is only one tightening portion, the tightening can be surely performed.

  The upper presser plate 31 and the lower presser plate 32 are formed with holding through holes 42 that coincide with the hole axis. In FIG. 5, the through hole 42 is provided through the tube holding material 2, but the length of the tube holding material 2 is shortened so that the through hole 42 does not hook the tube holding material 2 (not shown). May be). In addition, when the side of the upper pressing plate 31 is bent into a rib shape, the bending strength of the upper pressing plate 31 is increased, so the through hole 42 may be provided at one location. Moreover, the fastening method of pressing plates is not particularly limited, and a general method such as a method of fastening a nut by screwing it onto a bolt inserted through the through hole 42 may be used.

  In FIG. 5 (a) or FIG. 5 (b), the length of the lower holding plate 32 is made longer than the length of the tube holding material 2, and the tube holder 1 is placed near the end of the floor support 8 in the vicinity thereof. A fixing through portion 43 for connecting and fixing to the supporting bolt 81 is provided. Although not shown, the lengthened pressing plate may be elongated on the upper side, the lower side, or both, and the fixing through-hole 43 may be provided in the elongated position.

  The shape of the fixing through-hole 43 is not particularly limited, but a long hole is provided in case there is a slight displacement of the floor support 8 when the pipe fixture 1 is connected and fixed to the floor support 8 (described later). It is often said. As other shapes, for example, various shapes as shown in FIG. 6 are given as an example because of the ease of work.

  FIG. 6 shows an example of a pressing plate (for example, the pressing plate 32) connected to the supporting bolt 81 of the floor support 8. FIG. 6A is a plan view of an example in which long holes are provided at both sides of the holding plate and open to the side sides, and FIG. 6B is an opening at both ends of the holding plate at the end in the length direction. FIG. 4C is a plan view of an example in which long holes are provided, and FIG. 8C is a plan view of an example in which long holes that are open on the side of one end of the holding plate and the end of the other end in the length direction are provided. FIG. 4D is a plan view of an example in which a long hole is further provided in the longitudinal direction at the back of one of the long holes in FIG.

  In FIG. 6A to FIG. 6D, when connecting the holding plate 3 of the tube fixture 1 to the support bolt 81, it is necessary to first insert the support bolt 81 into the fixing through hole 43. Absent. Further, in FIGS. 4B to 4D, the pressing plate can be moved in the length direction even if the position of the supporting bolt 81 is slightly shifted, so that the pipe fixture can be connected. .

  FIG. 7 is a cross-sectional view of an example of a pipe laying structure using the pipe holder 1 of the second aspect. In this example, description will be made using the tube fixture shown in FIG. 7A. However, the tube fixing method is the same for other types of tube holders such as FIG. 7B. Thus, each will be exemplified and will not be described repeatedly.

  The pipe holder according to the second aspect of the present invention is a pipe fixing tool used when piped under the floor of a double floor. The double floor is supported by a floor support 8 placed on the base surface, and the base It is a double floor with a space between it and the floor. The floor support 8 has a main body as a support bolt, and the floor is placed on and supported by a lifting base screwed into the support bolt to support the floor. Planarization can be performed.

  A plurality of pipes P1, P2,... Coming out of a pipe header (not shown) and piped to each water use facility and equipment (none shown) are an upper pipe holding material 21 and a lower pipe holding material. 22 between the two. The holding plates 31 and 32 are each provided with a holding through hole 42, and a bolt 61 is inserted into the through hole 42, and the holding plates 31 and 32 are fastened together by the nut 7.

  The tube holding member 2 is held by clamp plates 31 and 32 that are tightened. Since the upper tube holding member 21 is flexible and the lower tube holding member 22 is relatively elastic compared to the upper tube holding member 21, it is sandwiched between the held tube holding members 21 and 22. The amount of deformation that the tube holding members 21, 22 receive by the pipes P 1, P 2,... Is larger in the upper tube holding member 21 than in the lower tube holding member 22.

  Therefore, the lower tube holding member 22 is slightly depressed along the outer diameter of the tubes P1, P2,..., And the upper tube holding member 21 is greatly depressed along the tube outer diameter, and the tubes P1, P2,. The pipes P1, P2,... Are held and fixed between the pipe holding materials 21, 22 in a state where a substantially triangular cavity is formed at the contact point where the upper pipe holding material 21 and the lower pipe holding material 22 intersect. Is done.

  The upper presser plate 31 or the lower presser plate 32 is lengthened (shown in the example in which the upper presser plate is lengthened), and a fixing through-hole 43 is provided at the elongated position. The fixing through-hole 43 is inserted into the supporting bolt 81 of the floor support 8 of the double floor, and is fixed by a nut (not shown) screwed into the supporting bolt 81, etc. The holding bolt or nut protruding on the lower surface is arranged so as to float from the base B.

  In this way, since the pipe holder 1 is held in a state of floating from the floor, and the pipe holders 21 and 22 are also made of foamed resin, the falling sound of the fluid flowing in the pipes P1, P2,. Is buffered by the lower tube holding member 22 and is not transmitted to other floors.

  The pipe laying procedure for making this pipe laying structure is as follows. When the pipes P1, P2,... Are piped on the double floor portion, first, the upper pressing plate 31 (or the lower pressing plate 32) is used as the floor support. 8 is inserted into the support bolt 81, and a space in which a nut or the like can be inserted is provided below the lower pressing plate 32, and is fixed with a nut or the like (not shown). Next, the pipes P1, P2,... Are arranged between the pipe holding members 21 and 22, the holding bolts 61 and the like are inserted into the holding through holes 42, and the upper holding plate 31 and the lower holding plate 32 are connected. Tighten and hold the tube holding members 21, 22 to deform and fix the pipes P1, P2,.

  The bolt 61 head or nut 7 projecting from the lower part of the lower presser plate 32 does not contact the base G because the tube holder 1 is fixed in the middle of the height of the support bolt 81 of the floor support 8. In addition, since the pipe holding material 2 is a foamed resin, the noise of the liquid flowing through the pipes P1, P2,... And the vibration of the pipe itself are not transmitted to the floor board F or other floors.

  When changing the direction of the piping at a later date, such as remodeling, loosen the anchor bolts, release the holding force of the tube holding members 21 and 22 and return the deformation to the base, and free the tubes P1, P2,. The pipe can be fixed again simply by changing the piping direction and then fastening the anchor bolt again. At this time, even if the pipe directions of the respective pipes are different, the pipe holding members 21 and 22 are deformed along the pipe direction of the new pipe, so there is no problem in fixing the pipe.
