Description

  The present invention relates to a fluid piping in a facility in a building and a plant-based fluid piping in a factory or the like, and particularly relates to a flexible fluid piping.

Conventionally, fluid piping such as water supply piping, hot water supply piping, cold / hot water piping, drainage piping, chemical piping, and plant piping in factories in air conditioning and sanitary facilities in buildings is directly connected to the pipes and joints in the field. It is built by that. Such straight pipe and joint connection methods include screw connection, welding connection, flange connection, mechanical connection, brazing connection, and the like.
In any pipe connection method, the straight pipe uses a so-called fixed pipe with a fixed pipe length that is mass-produced in a factory or the like, and a predetermined line based on the construction drawing in which the worker describes the fluid pipe route on site. After cutting and machining to a length of, fluid pipes are constructed by connecting straight pipes with joints.

  The above prior art is a technique generally known to those skilled in the art, and does not relate to a known literature invention.

  When constructing fluid piping by connecting conventional straight pipes and joints in the field, the accuracy of the connection work in the field depends largely on the skill of the worker, but in recent years, the number of skilled workers has been decreasing. The accuracy is decreasing due to the decrease in the skill of the workers. In particular, pipe connection work in areas where multi-system fluid pipes are complicated and pipe connection work in narrow spaces are difficult, and workers with insufficient skills are prone to poor pipe connection, resulting in fluids resulting from them. Leakage accidents have been increasing, which has been a major issue.

  In recent years, due to significant improvements in building technology, the construction period of new buildings has been significantly shortened compared to before. In response to this shortening of the work period, it has become impossible to deal with piping work by conventional workers at the site, and in order to respond to the shortening of the work period, the number of workers has been increased, which greatly reduces personnel. There were issues such as increased costs.

  In conventional pipe connection work in the field, a standard pipe and a joint are prepared for each work point, and each worker cuts the standard pipe with respect to the fluid piping route of the construction drawing and the cut pipe and joint. Therefore, it was difficult to assign the pipe cutting dimensions in a planned manner. As a result, the occurrence rate of so-called mill ends, which are pipes of unusable length, has increased, and the mill ends have to be treated as industrial waste or recycled to the pipe manufacturer. In the case of processing as industrial waste, there are problems such as high processing costs and waste of resources. In addition, when it is recycled, it is reworked into a standard pipe, but there is a problem that energy is wasted during rework.

Conventionally, straight pipes that are mass-produced in factories have a very long total length of 4 meters and 5.5 meters, and are made of a highly rigid material. There was a problem that the transportation cost was high and a large occupied space was required for storage.
Conventionally, in the case of standing pipe construction over a plurality of floors of fluid piping in a building, it is necessary to provide circular openings in advance on all floors through which the standing pipes are inserted. And, for efficient construction, shifting the vertical pipe route in the horizontal direction is kept to a minimum. Therefore, normally, it is desirable that the center position of the circular opening of each floor through which the standing pipe is inserted does not shift. However, the center position of the circular opening on each floor often shifts somewhat due to errors in the building frame. Conventionally, in order to absorb this error, the diameter of the circular opening is made significantly larger than the diameter required for fluid piping insertion. I was taking the way. However, the gap between the outer peripheral surface of the fluid piping and the circular opening that occurs after the fluid piping is inserted into the circular opening must be filled with a filler such as mortar or rock wool. In the above fluid piping insertion method, there is a problem that a larger gap is formed by greatly increasing the diameter of the circular opening, and a large amount of filling is required. Further, the filling work requires a lot of time and labor, and there is a problem that the work efficiency is poor.

  On the other hand, in recent years, a prefabricated method has been developed for the purpose of shortening the work time on site, reducing labor costs of workers, and improving the accuracy of pipe connection. This prefabricated construction method creates a pipe layout diagram that divides the fluid piping route into block units of a size that is easy to carry into the site based on the construction drawing that describes the fluid piping route created on site. Based on this, cutting the standard pipe at the factory, welding the joints, etc., create an integrated machined pipe and bring it into the site. A fluid pipe can be constructed simply by connecting the connection ends of the processed pipe. Such a fluid pipe prefabrication method was able to shorten the pipe connection time and reduce the labor cost of workers, and had a certain effect.

However, in order to exert the effect in the prefabrication method for fluid piping, first, the fluid piping route of the construction drawing manufactured on site must be accurate and appropriate. Since there are beams, floors, etc. in the building frame, the fluid piping route must be examined from a three-dimensional viewpoint and expressed in the construction drawing of the two-dimensional drawing. For example, when a fluid piping route is determined, when passing through beams, floors, etc., these must be avoided in principle. In addition, even when fluid pipes are pierced through beams and floors, there are parts of the beams and floors that cannot be penetrated due to the building structure. If a fluid piping route that violates these rules is set in the construction drawing, the person in charge at the factory who does not know the situation at the site will create a pipe drawing as it is, and the factory worker will use this pipe drawing as a basis. A processing tube is created and delivered to the site. Of course, the pipes that have been delivered do not fit the actual conditions at the site, so fluid piping cannot be constructed. As a result, the processing pipes for the nonconforming parts will be dimensioned at the site and recreated at the factory. There is a problem that if the trouble occurs frequently, the pipe connection work time becomes longer than before, which hinders shortening of the work time. In addition, it has been a problem that led to increased costs due to reordering. In addition, when a non-conforming portion of the processed tube is picked up at the factory and reprocessed, a portion that cannot be reused is generated, resulting in a waste of resources and a problem.
In addition, if the accuracy of the building frame is low and a large error occurs between the building drawings at the site, construction drawings will be created based on the building drawings, and errors will also occur in the fitting of the fluid piping route. As a result, there was a problem that a large number of non-conforming parts were produced.

  The present invention has been made to solve the above-described problems, and the number of pipe connection points can be greatly reduced compared to the case where fluid pipes are constructed with conventional straight pipes and joints. It is an object of the present invention to provide a fluid piping that can greatly reduce the number of defective parts and can greatly reduce the incidence of fluid leakage accidents.

The flow path holding mechanism is photocured inside the pipe wall of the fluid pipe. It is characterized by embedding a functional resin.

According to the present invention, the following various excellent effects can be obtained.
(1) Since the fluid piping of the present invention has a flow path holding mechanism that is formed of a flexible resin material and holds the flow path cross-sectional shape, between the two equipment devices, When constructing a fluid piping with one flow path such as between equipment and between equipment and between the equipment and the flow branch, install one fluid piping by bending it along the planned route, etc. It is only necessary to connect to equipment, instruments, and flow path branching parts, so it is possible to greatly reduce the number of pipe connection points compared to the case of constructing fluid piping with conventional straight pipes and joints, and The piping connection failure location can be greatly reduced, and as a result, there is a great effect that the rate of occurrence of fluid leakage accidents can be greatly reduced.
In addition, there is an effect that the construction time of the piping can be significantly shortened, and since the working time of the piping construction worker can be shortened, there is also an effect that labor costs can be significantly reduced.
Furthermore, since the number of pipe connections is greatly reduced, the number of pipe cuts is also greatly reduced, which makes it possible to significantly reduce the generation rate of scraps and treat them as industrial waste. In addition to significantly reducing the processing cost of the processing, the energy consumption during reworking when turning the mill ends for recycling can be significantly reduced.
(2) Since the fluid piping of the present invention has flexibility, it can be wound around a drum or the like, and can reduce labor during transportation / carrying-in and drastically reduce transportation costs, and can also be used for storage.

(3) In the standing pipe construction with the fluid pipe of the present invention, the fluid pipe has flexibility even if the center position of the circular opening through which the fluid pipe on the upper and lower floors is slightly shifted. The pipe can absorb the deviation, and therefore, the diameter of the circular opening can be suppressed to the minimum necessary diameter for the fluid piping to be inserted, and the diameter of the circular opening as in the related art is increased. There is a great effect that all the problems that occur due to the fact that the packing after the insertion of the vertical tube is large and the problems that require a lot of time and labor for filling the packing can be solved.
(4) Also, in the fluid piping of the present invention, due to the low accuracy of the building frame, if there is an error between the actual location of the fluid piping route on the construction drawing, use the flexibility, It is possible to absorb the error, and there is a great effect that it is possible to greatly reduce the occurrence of a non-conforming portion of the processed pipe as in the prefabricated method.

Hereinafter, an embodiment of the present invention will be described.
Embodiment 1 FIG.
1 is a plan view showing a fluid piping according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG.
In the figure, a fluid pipe 1 is composed of a tube main body 2 formed of an elastic resin material and a rigid wire 3 wound spirally around the outer peripheral surface of the tube main body 2. More specifically, the fluid pipe 1 is formed of a flexible resin material in which the pipe body 2 has elasticity, and the pipe wall thickness withstands the maximum design pressure of the internal pressure according to the material of the resin to be applied. The thickness has the strength to obtain.

  Examples of the resin material applicable to the tube body 2 include soft polyvinyl chloride, polyvinylidene chloride, ABS resin, polyethylene, polypropylene, fluororesin, polyamide, polycarbonate, ionomer, polyurethane, and polyester elastomer. . In addition, a rubber-based resin material can also be applied to the tube main body 2. Natural rubber, isoprene rubber, styrene / butadiene rubber, butadiene rubber, butyl rubber, ethylene propylene rubber, chloroprene rubber, chloro Sulfonated polyethylene, nitrile rubber, acrylic rubber, epichlorohydrin rubber, urethane rubber, polysulfide rubber, silicon rubber, fluorine rubber and the like are applicable.

  On the other hand, the wire 3 is spirally wound in the circumferential direction of the tube main body 2 and becomes a flow path holding mechanism for holding the tube main body 2, and the wire 3 is a tube of the tube main body 2. A raised portion 2a is provided on the outer peripheral surface of the tube main body 2 so as to cover the wire 3 and is embedded in the meat.

  As a material applicable to the wire 3, when a highly rigid metal such as iron, steel, stainless steel, titanium, or a resin material having a high rigidity such as polyacetal or polycarbonate is used, the channel retention of the channel retention mechanism. The ability can be increased, which is preferable. In particular, a piano wire having high bending characteristics is optimal.

The fluid pipe 1 shown in FIGS. 1 to 3 is a case where a fluid such as a horizontal main pipe or a side branch pipe is arranged in a horizontal direction, and this fluid pipe 1 is supported by being suspended by a dedicated pipe support 4. Has been.
The pipe support 4 includes a pipe band part 5 that sandwiches the fluid pipe 1 and a suspension support part 8 for hanging and fixing the pipe band part 5 from a ceiling or the like. This will be described below.
First, as shown in FIG. 3, the pipe band portion 5 is formed by aligning a pair of half bands 51, 52 formed in a semicircular cross section in an annular shape and rotating one end of both of them with a pin P (opening / closing). It has a structure that is freely connected, and outward flanges 51a and 52a that are joined when the half bands 51 and 52 are closed in an annular shape are formed at the other ends of the half bands 51 and 52, respectively. The flanges 51a and 52a are integrally formed and detachably fastened with bolts B1 and nuts N1.
Therefore, when the fluid pipe 1 is sandwiched in the pipe band portion 5, the bolts B1 and nuts N1 of the flanges 51a and 52a are removed, and the half bands 51 and 52 are rotated around the connecting pin P and opened. .

  Further, groove portions 511 and 521 are provided on the inner peripheral surfaces of the half bands 51 and 52 so as to correspond to the raised portions 2 a of the fluid piping 1, and when the fluid piping 1 is fixed to the piping band portion 5. The raised portion 2a and the groove portions 511 and 521 are fitted. As a result, even if the fluid piping 1 has flexibility, the position in the tube axis direction can be obtained even when the pulsation phenomenon of the fluid piping 1 due to the pressure fluctuation of the fluid flowing in the fluid flow path 1a occurs. It is possible to prevent deviation.

  On the other hand, the suspension support portion 8 includes a relay nut receiver 9, a relay nut 10, and a suspension bolt 11. As shown in FIG. 3, the relay nut receiver 9 has a structure in which the upper part is formed in a U-shaped cross section and the lower end part is bound, and a hole through which the bolt B1 can be inserted into the binding part 9a. The binding portion 9a is sandwiched between the flanges 51a and 52a of the half bands 51 and 52, and the piping band portion 5 is detachably connected by bolts B1 and nuts N1. Further, a circular opening 9b (see FIG. 2) is provided at the center of the top of the relay nut receiver 9, and a suspension bolt 11 is rotatably connected to the circular opening 9b via a relay nut 10. . More specifically, the relay nut 10 has a locking piece 10a on the outer periphery of the lower end, and the relay nut 10 is attached to the lower end of the suspension bolt 11 inserted into the circular opening 9b of the relay nut holder 9 from above. The relay nut 10 and the relay nut holder are rotated by being fitted into the circular opening 9b from below while being screwed together and locking the locking piece 10a at the lower end of the relay nut 10 to the lower peripheral edge of the circular opening 9b. A relay nut receiver 9 is attached to the suspension bolt 11 so as to be freely movable. For example, in the case of a building, the suspension bolt 11 has an upper end screwed to an insert embedded in ceiling concrete and is suspended, and is relayed to the lower end of the suspension bolt 11 as described above. The nut 10 is screwed and the fluid piping 1 is suspended and fixed from the ceiling.

  Regarding the construction method of the fluid pipe 1 described above, a flow path such as a fluid pipe that transports fluid between two equipment devices or a fluid pipe that transports fluid between equipment equipment and a device such as a fluid outlet A case of a one-channel system pipe without a branching part on the way will be described. First, a fluid pipe having a length corresponding to the planned route of the fluid pipe planned in advance is prepared. Next, the connection port according to the connection port classification (for example, flange connection, mechanical connection, screw connection, welding connection) of the equipment or instrument to be connected is joined to both ends of the fluid piping. Then, the fluid piping is arranged along the planned route. At this time, a bent pipe portion is formed by utilizing the flexibility of the fluid pipe 1 for a portion that bends to 90 degrees, 60 degrees, 45 degrees, etc. in the planned route.

  When a curved pipe part is formed with a normal flexible pipe, an inner tubular part with a small curvature and an outer tubular part with a large curvature are generated, and the inner tubular part shrinks due to compressive stress in the tubular part. However, in the outer tubular portion, the tensile stress acts in the tubular portion and it is elongated. Then, when there is a situation where the radius of curvature must be reduced at the 90 degree bend in the planned route due to some restrictions, the shrinkage limit of the inner tube meat is exceeded, and the elongation limit of the outer tube meat is exceeded. End up buckling. At this time, the cross-sectional area of the flow path in the fluid pipe becomes extremely narrow, and the role of conveying the fluid cannot be achieved.

  In that respect, in the fluid pipe 1 according to the first embodiment of the present invention, the pipe 1 is bent when the shrinkage limit or extension limit of the pipe is exceeded, but the rigid wire 3 is spirally wound along the circumferential direction and the pipe wall. Since it is embedded in the inside, the portion where the tube is bent is only the tube portion between the helical pitches of the wire 3 and only a minute bend is required. For this reason, there is hardly any change in the cross-sectional area of the flow path in the fluid pipe 1, and the role of transporting the fluid is not hindered.

  As for the method of supporting the fluid piping 1, in places having a ceiling such as in a building, an insert is embedded in the ceiling in advance and the piping support 4 shown in FIGS. A method of screwing onto the insert and supporting it from the ceiling is applied.

  On the other hand, when there are a plurality of fluid pipes 1 to be supported simultaneously, the pipe band portion 5 shown in FIG. 3 is fixed to a pipe bracket (not shown) by welding, bolts, nuts, etc., and the pipe bracket is attached to the wall / floor. Apply the method of supporting from the wall or floor using a thing fixed to etc. Thereby, the number of the piping support tools 4 can be reduced, and there exists an effect that construction time and the time which piping support work requires can be reduced.

FIG. 4 is a cross-sectional view showing Modification 1 of the pipe support applied to the fluid pipe according to Embodiment 1 of the present invention, and the same components as those in FIGS. Is omitted.
The piping support 4 shown in FIG. 4 is particularly suitable for use in the vertical fluid piping 1 that penetrates the upper and lower floors in equipment piping in a multi-storey building. As the piping support 4, a piping band portion 5 described below is applied. The piping band portion 5 shown in FIG. 4 has grooves 511 and 521 on the inner peripheral surface corresponding to the raised portions 2a of the fluid piping 1 like the piping band portion 5 shown in FIGS. The flanges 51a, 52a, 51b, 52b are provided at both ends of the half bands 51, 52, and the flanges 51a, 52a and the flanges 51b, 52b are fastened with bolts B1, N1 and B2, N2. Each of the fastening flanges 51a, 52a and 51b, 52b has a configuration in which a section steel 12 such as an L-shaped steel is joined as a floor support material. Then, a plurality of bolt holes provided in the shape steel 12 are inserted into anchor bolts 13 provided in advance in the floor near the floor through hole, and tightened with a nut 15 via a washer 14, whereby the pipe support 4 is fixed. It is fixed on the floor. As a result, the vertical fluid pipe 1 can be supported and fixed to the floor surface.

  In the above, when there is a place where the planned route of the fluid pipe 1 branches in two or more directions from the middle, a branch joint (not shown) is arranged at the branch place. Then, the fluid pipe 1 connects and constructs between the equipment and the branch joint, between the instrument and the branch joint, and between the branch joint and the branch joint. The connection method between the branch joint and the fluid piping 1 may be any connection method as long as the fluid in the fluid piping 1 does not leak, such as flange connection, mechanical connection, screw connection, and weld connection.

  In addition, in the construction site of fluid piping 1, the installation position of equipment may deviate from the initial planned position due to various circumstances, and the total length of the planned route of fluid piping may be somewhat extended. In particular, in the case of building equipment piping, it often crosses or runs parallel to other equipment piping and ducts, and if construction errors or the like of these equipment piping occur, the planned route of fluid piping 1 It may need to be corrected. Also, in vertical piping, when passing through the floor, floor through holes that are provided in advance during construction work, and in horizontal piping, when passing through walls, through wall through holes and beams that are provided in advance. If there are errors in the construction of the beam through holes that are provided in advance, it is often impossible to reopen these holes after building construction due to the strength of the floor, walls, and beams. In many cases, the planned route of piping is corrected. For these reasons, it is desirable that the total length of the fluid pipe 1 is a length that allows a slight margin from the planned route.

  The pipe support 4 shown in FIGS. 1 to 3 may have a structure in which a rubber, a spring, a hydraulic damper, or the like is connected between the relay nut 10 and the relay nut receiver 9. Alternatively, the suspension bolt 11 between the ceiling and the relay nut 10 may be divided into two on the ceiling side and the relay nut 10 side, and connected to each other via rubber, a spring, a hydraulic damper, or the like. Further, in the case of a support method of a structure in which the pipe band portion 5 is fixed to the pipe bracket, a structure in which a rubber, a spring, a hydraulic damper, or the like is connected between the pipe band portion 5 and the pipe bracket may be employed. With these connection methods, the vibration of the fluid pipe 1 caused by the pulsation of the fluid flowing in the fluid pipe 1 and the vibration of the equipment connected to the fluid pipe 1 are propagated. It is possible to absorb noise and to prevent noise troubles such as the body-borne sound caused by the propagation of vibrations to the building.

  In the fluid piping 1 according to the first embodiment described above, the tube main body portion 2 is formed of an elastic resin material, and the wire 3 having rigidity is wound spirally in the circumferential direction of the tube meat portion of the tube main body portion 2. In either case, each of the equipment, equipment, and branch joints is connected between two equipment, between equipment and equipment, or provided with a branching part in the middle. The pipes in the section need only be arranged and connected by bending one fluid pipe 1 along the planned route. For this reason, there is an effect that the construction time of the piping can be greatly shortened, and since the working time of the piping construction worker can be shortened, there is also an effect that labor costs can be significantly reduced.

Conventionally, when there is a bent part in the planned route, fluid piping must be constructed by connecting straight pipes and joints in combination.Therefore, the number of construction defects due to an increase in the number of joints and this However, in the fluid piping 1 according to the first embodiment, since there are only connection points with equipment, instruments, and branch joints, there is a large number of poorly constructed parts. As a result, the rate of occurrence of fluid leakage accidents can be greatly reduced.
Further, according to the first embodiment, the raised portion 2a is provided on the outer peripheral surface of the pipe main body portion 2 of the fluid pipe 1, and the raised portion 2a is provided on the inner peripheral surface of the half bands 51 and 52. , 521 and the fluid piping 1 is fixed to the piping band portion 5, so that the fluid piping 1 having flexibility can be surely fixed to the ceiling, wall, floor or the like.

  In the case of standing pipe construction over a plurality of floors of fluid piping in a building, it is necessary to provide a circular opening in advance on all floors through which the standing pipe passes. And, for efficient construction, shifting the vertical pipe route in the horizontal direction is kept to a minimum. Therefore, normally, it is desirable that the center position of the circular opening of each floor through which the standing pipe is inserted does not shift. However, the center position of the circular opening on each floor often shifts somewhat due to errors in the building frame. Conventionally, in order to absorb this error, the diameter of the circular opening is made significantly larger than the diameter required for fluid piping insertion. I was taking the way. However, the gap between the outer peripheral surface of the fluid piping and the circular opening end that occurs after the fluid piping is inserted into the circular opening needs to be filled with a filler such as mortar or rock wool. In the above fluid piping insertion method, there is a problem that a larger gap is formed by greatly increasing the diameter of the circular opening, and a large amount of filling is required. In addition, the filling operation requires a lot of time and labor, which is a problem.

In that respect, in the vertical pipe construction in the fluid pipe 1 according to the first embodiment, the fluid pipe 1 has flexibility even if the center positions of the circular openings on the upper and lower floors are slightly shifted. It is possible to absorb the deviation by the standing pipe made of the fluid pipe 1, and therefore, the diameter of the circular opening can be suppressed to a minimum necessary diameter for the fluid pipe 1 to be inserted, and the above-mentioned problem There is a big effect that all can be solved.
In addition, if the outer peripheral surface of the fluid piping around the circular opening end is wound with a heat-expandable refractory material having the property of expanding by heat, filling work such as mortar and rock wool becomes unnecessary, and the filling work time is reduced. Further reductions may be made.

Conventionally, in the pipe construction method using straight pipes and joints, the straight pipes that are mass-produced at the factory are very long, with a total length of 4 meters or 5.5 meters, and are made of a highly rigid material. Although a great amount of labor was required for carrying in, the fluid piping 1 according to the first embodiment can be wound around a drum or the like due to its flexibility, reducing labor during transportation and carrying in to the piping construction site, and The transportation cost can be greatly reduced, and the exclusive area during storage can be greatly reduced.
When renovation work is performed to update the fluid piping in the existing building to a new one, the fluid piping to be removed and newly installed by the elevator in the building must be carried in and out, and cut with an electric saw or the like in a narrow work space. In addition, since the newly installed fluid pipe has to be formed of a short-length processed pipe, the effect of applying the fluid pipe 1 according to the first embodiment is particularly great.
Furthermore, in tenant relocation work, etc. at department stores, etc., it was necessary to remove the connected fluid piping and re-install the fluid piping after the device relocation, even if only some equipment was relocated. Since the fluid piping is flexible by applying the fluid piping 1 according to the first embodiment, if the piping laying length does not change much before and after the facility equipment transfer, the fluid piping is moved while connected. If the length of the newly installed pipe is short, it is only necessary to add the insufficient amount of fluid pipe. Therefore, the working time can be greatly shortened and the cost can be drastically reduced, and the working time of the tenant relocation work is often limited outside the business hours of the department store, which is particularly effective.
In the case of conventional fluid piping made of vinyl chloride or the like, although the rigidity is high, the expansion / contraction rate due to temperature change is large, so it is necessary to relay expansion joints at regular intervals to absorb the expansion and contraction of the fluid piping. However, since the fluid piping 1 according to the first embodiment has flexibility, it can absorb expansion and contraction due to a temperature change, and there is an effect that an expansion joint is unnecessary.
In the case of conventional outdoor underground underground pipes, when using steel pipes, use steel pipes with an outer surface coated with resin, and in bent parts, connect straight pipes with joints and then coat with anticorrosion tape, etc. There was a need. Also, during excavation work for laying pipes, a work space for workers to perform pipe connection work is required in addition to the fluid pipe space. Furthermore, when using resin pipes made of vinyl chloride or the like that do not cause corrosion, the depth of burial had to be examined so that the pipe would not be damaged by earth pressure after laying the pipe. In the case of laying underground underground piping, it was also necessary to perform piping via expansion joints in consideration of ground subsidence. By applying the fluid piping 1 of the first embodiment, it is possible to greatly reduce the work for countermeasures against corrosion, and there is a great effect that the expansion joint is not required without being damaged by earth pressure. is there.
When the fluid piping 1 is composed of highly rigid pipes and joints such as conventional steel pipes, when an external force due to an earthquake or the like is applied, the stress generated thereby concentrates on the pipe connecting portion, causing the pipe connecting portion to buckle. However, in the fluid piping 1 of the first embodiment, the pipe itself is flexible, so that stress is not concentrated on the pipe connection portion, and the pipe connection portion is Since it is minimal, such as connection with equipment and connection with branch joints, it has the effect of greatly reducing the rate of fluid leakage accidents caused by earthquakes.
In addition, you may apply the fluid piping 1 of this Embodiment 1 to piping which connects the piping of the building part in the equipment piping of a seismic isolation building, and the piping of a foundation part. Compared with the conventional seismic isolation joint, it is excellent in flexibility, and even if vibration such as an earthquake occurs by the pipe support 4, there is an effect that the fluid pipe 1 can be reliably fixed to the seismic isolation building.

Embodiment 2. FIG.
5 is a plan view showing a fluid piping according to Embodiment 2 of the present invention, FIG. 6 is a sectional view taken along the line CC of FIG. 5, and FIG. 7 is a sectional view taken along the line DD of FIG. The same or corresponding parts as those in FIG.
In the figure, the fluid piping 1 has a pipe body 2 formed of an elastic resin material and rigidity wound spirally around the outer peripheral surface of the pipe body 2 as in the first embodiment. Although it consists of the wire 3, the point which the wire exposed part 3a which the said wire 3 exposed is provided in the outer peripheral surface of the said tube main-body part 2 in the multiple places along the winding direction of the said wire 3 is the said point. This is very different from that of the first embodiment. In the first embodiment, the wire rod exposed portions 3a are provided at four locations on the top, bottom, and both side surfaces per circumference of the wire rod 3, but the wire rod exposed portions 3a are three, two, or five or more locations. It may be.

Even in the fluid pipe 1 shown in FIGS. 5 to 7 according to the second embodiment, as in the first embodiment, when the fluid such as the horizontal main pipe or the side branch pipe is arranged as a pipe for conveying in the horizontal direction. The fluid pipe 1 is suspended and supported by a dedicated pipe support 4.
The pipe support 4 includes a pipe band part 5 that sandwiches the fluid pipe 1 and a suspension support part 8 for hanging and fixing the pipe band part 5 from a ceiling or the like. This will be described below.

The structure of the space filled with the photocurable resin is the same as that in the fourteenth embodiment.

  The construction method of the fluid piping 1 according to the twenty-eighth embodiment is substantially the same as that shown in each of the fourteenth to twenty-sixth embodiments, but after the fluid piping 1 is disposed, The part which performs the operation | work which inserts the ultraviolet irradiator which can irradiate an ultraviolet-ray and hardens the said photocurable resin differs greatly. The ultraviolet light irradiated by the ultraviolet irradiator passes through the inner layer of the tube body made of a transparent material and reaches the photocurable resin, whereby the photocurable resin reacts and cures.

  As the ultraviolet irradiator, an ultraviolet irradiator using an ultraviolet lamp or an ultraviolet laser irradiator can be applied. In addition, the irradiation intensity of the ultraviolet irradiator, the irradiation distance to the pipe formwork and the irradiation time are the ultraviolet intensity of the ultraviolet light irradiated from the ultraviolet irradiator used, the ultraviolet intensity necessary for the photocurable resin to cause a curing reaction, It is good to calculate and adjust from the wall thickness required for the fluid piping formed with the photocurable resin and the ultraviolet transmittance of the piping formwork.

  In the twenty-eighth embodiment, a photo-curing resin material that is cured by ultraviolet rays is applied to the liquid resin agent, but a photo-curing resin material that is cured by visible light may be applied. In this case, since a simple irradiator such as a general-purpose halogen lamp is sufficient, the initial cost and running cost of the irradiator can be reduced. Further, since visible light is used, there is an effect that there is no influence on the human body of the worker.

  In the fluid piping 1 according to the twenty-eighth embodiment, in addition to the effects shown in the fourteenth to twenty-sixth embodiments, it is necessary to pay attention to moisture and moisture as in the case where a water curable resin is applied. Therefore, it can be transported and stored, and there is no need to handle a high-temperature fluid as in the case of applying a thermosetting resin, so that there is a great effect that the work can be performed safely. In addition, since the photo-curing resin has a very fast curing speed compared to the water-curing resin and the thermosetting resin, there is a great effect that the time required for the construction work of the fluid piping can be greatly shortened.
