  By the way, in recent floor heating systems, for example, as a connecting pipe connected to the header on the heat source device side, considering an increase in flow rate and an improvement in durability due to an increase in capacity of equipment, a larger diameter and high rigidity Since there is a tendency to use resin piping, at the time of construction, there is a fact that the rising part from the floor of the connecting pipe is likely to be violated, that is, the rising part is likely to bend in an irregular direction, and the workability is extremely poor. . Further, in the above-described system, there is a tendency that a larger number of communication pipes are gathered for one heat source device due to an improvement in the capacity of the heat source device and an increase in the number of rooms to be heated. A pair of connecting piping on the supply side and return side must be connected separately to a pair of headers for supplying hot water and collecting hot water attached to each main pipe on the side, and in the vicinity of the header Then, since a large number of connecting pipes are intertwined, routing and connecting the connecting pipes to the header becomes complicated during construction.

  The present invention has been made in view of the above circumstances, and the purpose thereof is a pipe assembly apparatus that aggregates and connects communication pipes to a main pipe connected to a heat source apparatus in a hot water supply system or an air conditioning system.

In various air conditioning systems that circulate media (liquid heat medium such as hot water, cold water, and cooling liquid), it is used to collect and connect a main pipe connected to a heat source device and a large number of communication pipes connected to each indoor facility. . Hereinafter, as an example of the piping assembly device of the present invention, a piping assembly device applied to a floor heating system that is one of the above-described cooling and heating systems will be described.

  As is well known, the floor heating system supplies hot water (heat medium) of about 40 to 80 ° C. from the heat source device to the floor heating panel laid on the floors of a plurality of living rooms, and radiates heat in the floor heating panel to lower the temperature. This is a system for heating the living room by returning the used hot water (heat medium) of about 30 to 60 ° C. to the heat source device, and the pipe assembly device of the present invention supplies hot water (heat medium) connected to the heat source device. It is used to connect a large number of connecting pipes on the supply side and the return side connected to the floor heating panel to each main pipe for recovery and recovery. The heat medium may be water or an alcohol solvent such as an antifreeze.

  As shown in FIG. 1, the pipe assembly apparatus includes a frame (1) configured in a box shape and installed on the floor, and a header (2) housed in the frame and connected to the main pipes. I have. The frame (1) uses four columns (11) and a plurality of beams (12) made of a metal extrusion mold or a flat plate, and is configured in a vertically long box shape. Although not shown, a design panel is attached to the outside of the frame (1).

  In the present invention, exposure of a rising portion of a communication pipe (3), which will be described later, is prevented, and the drawing-in height of the communication pipe (3) of the frame (1) is set to the arrangement level (height) of the communication pipe (3). Therefore, height adjustment means (not shown) for adjusting the height of the frame is provided at the lower part of the frame (1). As the height adjusting means, an adjuster bolt that is screwed in the vertical direction to the lower end of each column (11) and moves up and down by a rotating operation, and a long hole for screw insertion that is long in the vertical direction are provided. A leg member made of L-shaped steel or a square pipe, which is screwed to the lower end of the steel plate so as to be adjustable in height.

  The frame (1) is formed to have a size capable of accommodating at least the header (2) and the rising portion of the connecting pipe (3) connected thereto, but accommodates the heat source device (9). You may form in the magnitude | size to obtain. That is, in the piping assembly device of the present invention, when used in the floor heating system as described above, the heat source device (9) may be disposed on the upper portion of the frame (1). The heat source device (9) is, for example, a heat exchanger that heats a liquid heat medium in a container with an electric heater or steam and passes water through a serpentine tube inserted in the container, and the amount of water in the system. A storage tank for keeping the temperature constant, and a control device for controlling the liquid heat medium in the heat exchanger to a constant temperature and controlling the supply of the produced hot water, and the like.

  The heat exchanger of the heat source device (9) includes a hot water supply main pipe (91) (heat medium supply main pipe) for sending out hot water to the indoor equipment side, and a used hot water for returning the used hot water from the indoor equipment side. And a hot water recovery main pipe (92) (heat medium recovery main pipe). Each of the main pipes (91) and (92) is usually made of a metal such as copper or a copper alloy, stainless steel, iron or lead, or a synthetic resin such as vinyl chloride, polyethylene or polybutene, and its outer diameter is About 10 to 60 mm and the inner diameter are about 7 to 53 mm. As described above, since the heat source device (9) is preliminarily accommodated in the frame (1), it is not necessary to separately install the heat source device (9), and the floor heating system can be constructed more easily.

  The header (2) distributes the hot water produced by the heat source device (9) to the plurality of connecting pipes (3), and returns the used hot water returned from the plurality of connecting pipes (3) to the heat source device (9). Are attached to the hot water supply main pipe (91) and the hot water recovery main pipe (92) of the heat source device (9), respectively. That is, in the floor heating system, two headers are attached as the header (2): the hot water supply header (2a) (heat medium supply header) and the hot water recovery header (2b) (heat medium recovery header). .

  Each of the headers (2) is made of copper or copper alloy, stainless steel, iron, lead, or other synthetic resin having heat resistance and durability. The maximum temperature at which deformation does not occur is set to 95 ° C. or higher, preferably 120 ° C. or higher. As the resin constituting the header (2), a thermoplastic or thermosetting general-purpose resin or an engineering plastic is used.

  The above general-purpose resins include polyethylene (PE), polypropylene (PP), vinyl chloride (PVC), methacrylic resin (PMMA), polystyrene (PS), acrylonitrile / styrene resin (AS, SAN), acrylonitrile / butadiene / styrene resin. (ABS), ethylene vinyl acetate copolymer (EVA), ethylene-vinyl alcohol copolymer resin (EVOH) and the like.

  Engineering plastics include polyetheretherketone (PEEK), polysulfone (PSU, PSF), polyphenylsulfone (PPSU), polyethersulfone (PES), polyphenylene sulfide (PPS), and polyetherimide (PEI). ), Polyamide resin, nylon 6,66,610,11,12 (PA), polycarbonate (PC), fluorine resin (PTFE, FEP, PFA, ETFE, CTFE, PVDF), polyphenylene ether, polyphenylene oxide (PPE / PPO), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyarylate (PAR), polyamideimide (PAI), liquid crystal polymer (LCP), polyacetal (POM), polymethylpentene (T) X), polybenzimidazole (PBI), polyaminobismaleimide (PABI, PABM), polybismaleimide triazine (BT resin), olefin / vinyl alcohol copolymer (GL resin), phenol resin (novolak type), epoxy resin ( Bisphenol-based), diallyl phthalate resin, unsaturated polyester resin, polyimide resin (PI), melamine resin and the like.

  Engineering plastics are plastics used as so-called industrial materials such as industrial parts and housings, and are excellent in strength, impact resistance, heat resistance, hardness degradation, and the like. From the viewpoint of strength and heat resistance, the engineering plastics as described above are preferable, and PPS, PSU, PPSU and the like are particularly preferable in consideration of water resistance, cost and the like. The header (2) is manufactured by injection molding the resin as described above.

  The header (2) includes a main pipe portion connected substantially vertically to the main pipe (91) for supplying hot water or the main pipe (92) for collecting hot water, and a branch pipe portion branched in a horizontal direction from the main pipe portion. The branch pipe section has a plurality of connection ports (21) directed downward to which the connection pipe (3) arranged on the floor side below the header is connected. The header (2) has a piston-like valve member inserted into the lower end portion of the main pipe portion in order to separate the main pipe portion and the branch pipe portion during maintenance and management work. The main pipe portion at the end is configured to be openable and closable.

  The connection port (21) provided on the lower side of the branch pipe portion is configured as, for example, a female connection port with a ridge protruding at the tip, and a connection pipe ( 3) is connected. Specifically, a male joint having a bamboo shoot-like press-fitting portion that is press-fitted into an end portion of the communication pipe and a straight tubular insertion portion in which a ridge is projected at the base portion at the tip of the communication pipe (3) Such a joint is fixed to the connection port (21) by inserting its insertion part into the connection port (21), butting both ridges, and holding these ridges with a clip-shaped binding metal fitting. It is made to be done. A blind plug is attached to the unused connection port (21) including one connection port for testing.

  For the connecting pipe (3), a pipe made of a synthetic resin such as polyethylene (PE) or polybutene (PB) is usually used. In particular, as a constituent material of the communication pipe (3), a cross-linked polyethylene is suitable because it is excellent in chemical stability and durability. Generally, in an air conditioning system including floor heating, a connecting pipe (3) having an outer diameter of about 8 to 30 mm, preferably 10 to 13 mm, and a wall thickness of about 1 to 3 mm, preferably about 1.5 mm is used. . Such a connecting pipe (3) usually has a minimum bending radius (radius causing buckling) of about 30 to 700 mm, and a construction bending radius (bending radius serving as a guide during construction in consideration of safety against buckling). About 50 to 1200 mm, preferably the minimum bending radius is 60 to 80 mm and the construction bending radius is 100 to 200 mm. In particular, the minimum bending radius of a pipe made of crosslinked polyethylene is about 6 times the outer diameter, for example, the minimum bending radius of a connecting pipe (3) having an outer diameter of 10 mm is 60 mm.

  Therefore, in the conventional construction, connecting the connecting pipe to the header in an intertwined state concentrates the force from the header to one place where the connecting pipe rises downward, so that the minimum bending radius can be secured sufficiently. There is also a risk that the connecting piping will buckle. On the other hand, the pipe assembly apparatus of the present invention is a resin pipe as described above, and is suitable for a relatively rigid pipe that is crushed by a bending operation and easily buckles.

  In the present invention, in order to improve the workability during installation and maintenance, and to prevent buckling of the connecting pipe (3), below the header (2) is inside the frame (1) below the header. A partition member (4) that divides the region (6) (space) into a plurality of regions is disposed. As shown in FIGS. 1 and 3, the partition member (4) is constituted by, for example, an elongated U-shaped bar (or pipe). The U-shaped bar is arranged in a state of projecting inwardly from both side surfaces of the frame (1) by being attached to the mounting plate (41) spanning the front and rear columns (11) in a horizontal direction. Then, as shown in FIG. 3, the lower part of the header (2) is divided into two regions, for example, a region (61) and a region (62), by two sets of partition members (4) arranged in opposing states. Is done.

  Furthermore, a gap (42) is provided between the facing partition members (4) in order to facilitate the arrangement and construction of the communication pipe (3). That is, in the partition member (a set of facing partition members) (4), a gap (42) through which the connecting pipe (3) is inserted and removed in the horizontal direction with respect to the regions (61) and (62) partitioned thereby. ) Is provided. By providing such a gap (42), it is possible to arbitrarily move the rising portion of the communication pipe (3) between the region (61) and the region (62) during construction.

  The widths of the regions (61) and (62), that is, the distance between the regions (61) formed by the two partition members (4) adjacent to one side of the frame (1), and the partition member (4) And the space (62) formed by the beam (12) on the back side of the frame (1) is an interval through which only one connecting pipe (3) can be inserted. In other words, the widths of the regions (61) and (62) are less than twice the outer diameter of the communication pipe (3). By setting the widths of the regions (61) and (62) as described above, the rising portions of the connection pipe (3) are aligned in a line according to the arrangement of the connection ports (21) of the header (2). I can do it.

  In the pipe assembly device applied to the floor heating system, as shown in FIG. 3, the hot water supply header (2a) (heat medium supply header) and the hot water recovery header (2b) (heat medium recovery header) A plurality of forward connection pipes (3a) and return connection pipes (3b) are connected as connection pipes (3) to the connection ports. The forward connection pipe (3a) and the return connection pipe (3b) Are partitioned by different partition members (4) and accommodated in different regions (61) and (62). In addition, as a partition member (4), as long as the area | region (6) below a header (2) can be divided into plurality, the thing of appropriate structures, such as a flat plate and a linear bar, can be used, for example.

  Moreover, in this invention, in order to improve workability | operativity and to arrange | position a connecting pipe (3) without applying an excessive load, as shown in FIG.1 and FIG.2, in the lower part of a frame (1), floor side A pipe lifting prevention tool (5) for pressing the connecting pipe (3) routed in the horizontal direction to the floor side is detachably provided. In the present invention, the “floor side” refers to a portion including a floor base material supported by joists to a floor finishing material on the surface. Specifically, the communication pipe (3) is routed on the surface of the floor base material in the case of new construction, and on the surface of the floor finishing material of the existing floor in the case of renovation. By means of the tool (5), the connecting pipe (3) is pressed against the floor side, that is, the surface side of the floor base material or the surface side of the floor finishing material of the existing floor.

  As shown in FIG. 2 (a), for example, the tube floating prevention device (5) is configured by providing rising pieces (52) at both ends of a sleeper-shaped main body bar (51). In addition, each rising piece (52) is provided with a long hole (5c) along the protruding direction of the rising piece from the main body bar (51). Moreover, in a preferable aspect, in order to prevent the connection pipe from being damaged when the connection pipe (3) is pressed, an elastic material (53 such as urethane foam or rubber) is provided on the lower edge of the main body bar (51). ) Is attached.

  As shown in FIG. 2 (b), the pipe floating prevention device (5) is inserted into the insertion holes (not shown) provided in the front and rear columns (11) by inserting male screws (54) into the wing nut (55). By tightening each rising piece (52), the main body bar (51) is attached to the side surface of the frame (1) so as to be substantially horizontal. Since the pipe lifting prevention tool (5) as described above is easy to attach and detach, the connecting pipe (3) can be easily connected to the header (2), and the long hole (5c) is used. Since the mounting height can be adjusted, the connecting pipe (3) raised from the floor can be pressed with an appropriate force. In addition, as the pipe lifting prevention tool (5), the height is adjusted by selecting a plurality of screw insertion holes provided on the support column (11) side, or using a fixing tool such as a clamp. Various types of structures that are detachable and adjustable in height, such as those to be fixed, can be used.

At that time, the floor side connecting pipe (3) is initially temporarily loosely pressed so that it can be freely moved to some extent.

  The connecting pipe (3) is usually a so-called pair tube in which the outgoing connecting pipe (3a) and the return connecting pipe (3b) are paired, and the end of the pair tube is connected to the outgoing connecting pipe (3a) at the time of construction. It is separated from the return communication pipe (3b), but after temporarily connecting the connection pipe (3) with the pipe lift prevention tool (5) as described above, as shown in FIG. (3a) and the return communication pipe (3b) are arranged separately in the regions (61) and (62) using the partition member (4). Then, the length of the end is adjusted so that the bending of the rising portion of the connecting pipe (3) has an appropriate radius, and the outgoing connecting pipe (3a) is connected to the connection port (21) of the hot water supply header (2a). The connecting and returning communication pipe (3b) is connected to the connection port (21) of the warm water recovery header (2b).
