  Referring to FIG. 1, a pipe holder 10 according to an embodiment of the present invention includes a radiant air-conditioning system that cools or heats a building by radiation from a heat medium circulating in a heat exchange pipe 108 (for example, Hereinafter, the heat exchange pipe 108 is held by simply using the system 100).

  2-5, the pipe holder 10 includes a mounting plate 12 and a holding portion 14, and is formed by extruding a material having thermal conductivity such as aluminum. By forming the pipe holder 10 with a heat conductive material, a mounting portion described later and the heat exchange pipe 108 are thermally coupled. However, the material of the pipe holder 10 is not particularly limited as long as it is a heat conductive material.

  The attachment plate 12 is formed in a long rectangular shape, and is attached to the attachment portion using a screw 16 such as a tapping screw or a drill screw. In this embodiment, the lower surface of the deck plate 106 to be described later is an attachment portion for the pipe holder 10. The length in the longitudinal direction of the mounting plate 12 is, for example, 3000 mm, and the length in the width direction is, for example, 60 mm. Moreover, the thickness of the mounting plate 12 is 1 mm, for example. As can be seen from FIG. 3, the mounting plate 12 is curved in a direction (width direction) orthogonal to the longitudinal direction, and one surface is formed in a convex shape that draws a gentle arc, and the other surface is the convex shape. It is formed in a concave shape corresponding to the shape. A pair of holding portions 14 are provided on one surface formed in a convex shape so as to be continuous in the longitudinal direction, and the other surface of the concave shape is an attachment surface attached to the attachment portion.

  As shown in FIGS. 3 and 5, in the vicinity of the center in the width direction of one surface of the mounting plate 12, a substantially V-shaped cross-sectional view extending continuously in the longitudinal direction between a pair of support portions 14 b described later. A groove 18 is formed. This groove 18 is a mark for screwing. The groove 18 may be formed at the time of extrusion molding of the pipe holder 10, or may be formed by cutting after the molding. When the pipe holder 10 is attached to the deck plate 106, the pipe holder 10 is screwed on the groove 18 in the longitudinal direction of the attachment plate 12 at a predetermined pitch (for example, at a pitch of 300 mm). However, the pitch of screwing is not particularly limited.

  The pair of holding portions 14 are provided at a distance from each other and include a pair of receiving portions 14a and a pair of support portions 14b.

  The receiving portion 14a is provided on the distal end side of the pair of holding portions 14, and the cross section is formed in an arc shape having an inner diameter substantially the same as or slightly smaller than the outer diameter of the heat exchange pipe 108, and receives and holds the heat exchange pipe 108. To do. The distance between the tip ends of the pair of receiving portions 14a is slightly smaller than the outer diameter of the heat exchange pipe 108 so that the heat exchange pipe 108 can be held, and can be pushed into the receiving portion 14a. For example, 10 to 20 mm. When the heat exchange pipe 108 is attached to the receiving portion 14a, the inner peripheral surface of the receiving portion 14a is in close contact with the outer peripheral surface of the heat exchange pipe 108, and the heat exchange pipe 108 is sandwiched from the side.

  The support portion 14b is provided on the proximal end side of the holding portion 14, and connects the one surface of the mounting plate 12 and the receiving portion 14a and supports the receiving portion 14a. A space 20 (space) is formed between the pair of support portions 14b. The space | interval part 20 is larger than the height and width | variety of the head of the screw 16 for attaching the attachment board 12 to the deck plate 106, the height is 3 mm, for example, and the width is 8 mm, for example.

  Returning to FIG. 1, such a pipe holder 10 is used in a system 100 that performs cooling or heating in a building as described above. This system 100 is a ceiling structure 102 and is provided in a ceiling forming space of a construction floor in a building and used as it is as a ceiling. As shown in FIGS. 6 and 7, the pipe holder 10 is attached to a deck plate 106 that forms the lower surface of the ceiling slab 104, and holds the heat exchange pipe 108.

  Referring to FIGS. 8 and 9, deck plate 106 is formed by bending a steel plate or the like, and includes substrate portion 106a and reinforcing rib 106b. The substrate portion 106a is formed in a rectangular plate shape, and is provided so as to be aligned in the width direction orthogonal to the longitudinal direction. A plurality of reinforcing ribs 106b are provided on the lower surface of the deck plate 106 at intervals. The reinforcing rib 106b protrudes downward from one end in the width direction of the substrate portion 106a and continuously extends in the longitudinal direction of the substrate portion 106a. However, it should be pointed out that there are various known deck plates 106 and are not limited to those shown in FIG.

  Returning to FIG. 6 and FIG. 7, such a deck plate 106 is used as a discarded form when the ceiling slab 104 is formed in the building, and is passed between the ceiling beams 110.

  The pipe holder 10 is attached by screwing the attachment plate 12 to the lower surface of the deck plate 106. As shown in FIG. 6, two pipe holders 10 are provided between adjacent reinforcing ribs 106b, for example, and are arranged in parallel to the longitudinal direction of the reinforcing ribs 106b. By doing so, the space between the reinforcing ribs 22 can be used effectively.

  On the other hand, the heat exchange pipe 108 is attached to the holding portion 14 (receiving portion 14a) of the pipe holder 10.

  Referring to FIG. 10, a heat exchange pipe 108 is a known pipe member having a five-layer structure including an inner layer, an intermediate layer, an outer layer, and an adhesive layer (not shown) for bonding them, Pass the heat medium. The outer layer and the inner layer are formed of a resin such as polybutene or polyethylene, and the intermediate layer is formed of a metal such as an aluminum alloy or copper. However, the material of the heat exchange pipe 108 is not particularly limited. The inner diameter of the heat exchange pipe 108 is, for example, 10-20 mm, and the thickness dimension is, for example, 2.0-2.5 mm.

  Returning to FIGS. 6 and 7 again, such a heat exchange pipe 108 is bent in advance in a meandering shape including a straight tubular portion 108a and a folded portion 108b, and when it is piped, each straight tubular portion 108a. Is fitted into the holding portion 14 (receiving portion 14a) of the pipe holder 10 at the corresponding position, and is held in contact with the entire length of the pipe holder 10 in the longitudinal direction. As a result, the heat exchange pipe 108 is securely fixed and a sufficient contact surface for conducting heat between the pipe holder 10 and the heat exchange pipe 108 is obtained.

  Further, each end of the heat exchange pipe 108 passes through a through passage 104 a formed in the ceiling slab 104, is raised to the upper floor space 112, and is connected to the main pipe 116 in the floor space 112. The

  As shown in FIG. 1, the main pipe 116 is a pipe that connects the heat source unit 114 and each heat exchange pipe 108, and is connected to the upstream side 116 a connected to the downstream side of the heat source unit 114 and the upstream side thereof. A return path 116b is formed, and a piping path through which the heat medium circulates between the heat source device 114 and each heat exchange pipe 108 is formed.

  When the heat medium circulates in the heat exchange pipe 108, as described above, the heat exchange pipe 108 and the deck plate 106 are thermally coupled, so that heat from the heat medium flowing in the heat exchange pipe 108 is obtained. The heat is transferred to the deck plate 106 via the pipe holder 10, and heat radiation is performed by the deck plate 106. In addition, since the heat exchange pipe 108 is held in contact with the entire length of the pipe holder 10 in the longitudinal direction, the contact area with the pipe holder 10 is increased, and heat from the heat medium is efficiently supplied to the deck plate 106. It is transmitted. In addition, the pipe holder 10 itself functions as a radiating portion that performs heat radiation. Therefore, cooling or heating can be performed efficiently.

  Next, a method of attaching such a pipe holder 10 to the deck plate 106 will be described with reference to FIG. As will be described in detail below, since the pipe holder 10 is provided with the mounting plate 12, the mounting work of the pipe holder 10 can be performed easily and simply by screwing the mounting plate 12 to the lower surface of the deck plate 106. Can be done efficiently.

  Specifically, first, as shown in FIG. 11A, the attachment surface of the pipe holder 10 is brought into contact with the lower surface of the deck plate 106 to perform positioning in the longitudinal direction and the width direction. At this time, since the mounting surface of the pipe holder 10 is formed in a concave shape, a gap is formed between the central portion in the width direction of the mounting plate 12 and the deck plate 106.

  Next, as shown in FIG. 11B, the screw 16 is positioned on a groove (marked line) 18 formed near the center of one surface of the mounting plate 12. At this time, the groove 18 serves as a mark and serves as a guide, so that the screw 16 can be easily positioned. Further, since the screwing only needs to be performed on the marked line of the mounting plate 12, that is, at one central portion, the mounting operation becomes easier. Then, the mounting plate 12 is screwed from one side of the mounting plate 12 (screw 16 is screwed).

  Then, as shown in FIG. 11C, the body portion of the screw 16 passes through the mounting plate 12 and the deck plate 106, and its head portion is accommodated in the interval portion 20 of the pipe holder 10. Further, the bottom surface of the deck plate 106 and the mounting surface of the pipe holder 10 are in contact with each other without any gap by the force that the screw 16 presses on the marked line, that is, at the center portion of the mounting plate 12. The reaction force from 106 acts evenly on the entire contact surface (mounting surface). As a result, the pipe holder 10 is more stably fixed, and a sufficient contact surface for conducting heat between the pipe holder 10 and the deck plate 106 is obtained.

  Then, in the same manner, the pipe holder 10 is fixed to the lower surface of the deck plate 106 by screwing on the groove 18 of the mounting plate 12 at a predetermined pitch in the longitudinal direction.

  Further, when the heat exchange pipe 108 is attached to the pipe holder 10, the heat exchange pipe 108 is bent in a meandering shape including the straight tubular portion 108a and the folded portion 108b by using a pipe bender or the like in advance at a factory or the like. The heat exchange pipe 108 is attached to the pipe holder 10 by processing and inserting the straight tubular portion 108a of the heat exchange pipe 108 between the pair of holding portions 14 (receiving portions 14a). At this time, the inner peripheral surface of the receiving portion 14 a comes into close contact with the outer peripheral surface of the heat exchange pipe 108. Moreover, as shown in FIG. 7, the space | interval part 20 of the pipe holder 10 is covered from the downward direction with the heat exchange pipe 108, and the head part of the screw 16 which settled in the space | interval part 20 is hidden. This improves the appearance of the ceiling without exposing the head of the screw 16.

  In consideration of the design of the ceiling, the deck plate 106, the pipe holder 16, and the heat exchange pipe 18 may be preliminarily painted with the same color or the like. However, the paint may be a different color or may not be applied.

  Therefore, according to this embodiment, since the deck plate 106 and the mounting plate 12 are screwed together, the pipe holder 10 can be securely attached, and sufficient durability and strength are ensured. Therefore, in particular, when the attachment portion is a downward surface such as the lower surface of the deck plate 106 (the lower surface of the ceiling slab 104), it is preferable to employ the pipe holder 10. In addition, since the interval portion 20 for accommodating the head portion of the screw 16 is provided between the pair of support portions 14b, the head portion of the screw 16 is attached when the heat exchange pipe 108 is attached to the holding portion 14 (receiving portion 14a). Can improve the appearance without exposing.

  Next, another example of the pipe holder 10 will be described with reference to FIG. The pipe holder 10 shown in FIG. 12 is different from the pipe holder 10 described above in that the mounting plate 12 is formed flat in the width direction. Since the other configurations are the same, the same reference numerals are used for overlapping portions, and the description thereof is omitted or simplified.

  In the embodiment shown in FIG. 12, the pipe holder 10 includes a mounting plate 12 and a holding portion 14. The mounting plate 12 has a long rectangular shape and is formed flat in the longitudinal direction and the width direction. A pair of holding portions 14 are provided on one surface of the mounting plate 12 so as to be continuous in the longitudinal direction, and the other surface is a mounting surface that is mounted on a mounting portion such as a lower surface of the deck plate 106. Near the center of one surface of the mounting plate 12, a groove (mark line) 18 for screwing is formed between the pair of support portions 14b so as to extend in the longitudinal direction.

  The pair of holding portions 14 are provided at an interval and include a receiving portion 14a provided on the distal end side thereof and a support portion 14b provided on the proximal end side. The receiving portion 14a is formed in an arc shape whose cross section has an inner diameter substantially the same as the outer diameter of the heat exchange pipe 108, and receives and holds the heat exchange pipe 108. The support part 14b is provided between the one surface of the mounting plate 12 and the receiving part 14a, and supports the receiving part 14a. A gap 20 that is larger than the height and width of the head of the screw 16 is formed between the pair of support portions 14b.

  Such a pipe holder 10 is attached by screwing the attachment plate 12 to the attachment portion. In the test conducted by the inventor, even when the mounting plate 12 is formed flat in this way, when the mounting plate 12 is screwed to the mounting portion, a contact surface between the mounting portion and the mounting surface can be obtained to some extent. Was confirmed.

  Therefore, also in the embodiment shown in FIG. 12, the pipe holder 10 can be securely attached by screwing the attachment portion and the attachment plate 12 in the same manner as the above-described embodiment. Moreover, the pipe holder 10 can be stably fixed by the reaction force from the mounting portion.

  In each of the above-described embodiments, the mounting plate 12 is provided so as to extend outward in the width direction with respect to the pair of support portions 14b, but is not limited thereto. As shown in FIG. 13, the attachment plate 12 may be formed only between the pair of support portions 14b.

  In the embodiment shown in FIG. 13, the mounting plate 12 has a long rectangular shape and is formed between the pair of support portions 14 b and is not formed on both sides (outside) in the width direction. In this embodiment, the length in the longitudinal direction of the mounting plate 12 is, for example, 3000 mm, and the length in the width direction is, for example, 10 mm. A pair of holding portions 14 including a receiving portion 14a and a support portion 14b are provided on one surface of the attachment plate 12 so as to be continuous in the longitudinal direction, and the other surface is an attachment surface attached to the attachment portion. . The receiving portion 14a is formed in an arc shape whose cross section has an inner diameter substantially the same as the outer diameter of the heat exchange pipe 108, and receives and holds the heat exchange pipe 108. The support portion 14b is formed on the proximal end side of the holding portion 14, and supports the receiving portion 14a by connecting the one surface of the mounting plate 12 and the receiving portion 14a. Between the pair of support portions 14b, a gap portion 20 larger than the height and width of the head of the screw 16 for attaching the attachment plate 12 to the attachment portion is formed.

  Also in the embodiment shown in FIG. 13, the pipe holder 10 can be securely attached by screwing the attachment portion and the attachment plate 12 in the same manner as the above-described embodiment. Moreover, since the space | interval part 20 was provided between the attachment plate 12 and the receiving part 14a, when attaching the heat exchange pipe 108 to the holding | maintenance part 14 (receiving part 14a), the head of the screw | thread 16 is exposed. Absent.

  Moreover, the cross-sectional shape of the holding | maintenance part 14 is not limited to what is shown in each above-mentioned Example. For example, as shown in FIG. 14, the substantially S-shaped holding portion 14 may be formed by smoothly supporting the support portion 14b and the receiving portion 14a.

  Further, as shown in FIG. 15, claw portions 22 a and 22 b that can be locked to each other may be provided at the distal ends of the pair of holding portions 14 (receiving portions 14 a).

  Referring to FIG. 15A, in this embodiment, the pair of holding portions 14 are provided at a distance from each other, and include a pair of receiving portions 14a and a pair of support portions 14b.

  The receiving portion 14 a is formed on the distal end side of the holding portion 14 and has an arc shape whose cross section has an inner diameter slightly larger than the outer diameter of the heat exchange pipe 108. Claw portions 22a and 22b that can be locked to each other are formed at the distal ends of the pair of receiving portions 14a. The distance between the front end portions of the pair of receiving portions 14a, that is, the claw portions 22a and the claw portions 22b is set to a size that allows the heat exchange pipe 108 to be pushed in, and is, for example, 10-15 mm.

  The support portion 14b is formed on the proximal end side of the holding portion 14, and extends from the one surface of the mounting plate 12 to the receiving portion 14a while being slightly inclined toward both sides (outside) in the width direction. A spacing portion 20 is formed between the pair of support portions 14b.

  When the heat exchange pipe 108 is attached to such a pipe holder 10, the heat exchange pipe 108 is pushed in between the pair of holding portions 14 (receiving portions 14a). Then, the receiving portion 14a is elastically deformed by applying a force from the outside so as to reduce the diameter, and the claw portions 22a and 22b formed at the tip end portions are locked. Then, as shown in FIG. 15B, the tip portions of the pair of holding portions 14a are closed without a gap, and the inner peripheral surface of the receiving portion 14a and the outer peripheral surface of the heat exchange pipe 108 are substantially in the tube circumferential direction. It comes in close contact over the entire circumference. Further, at this time, the head of the screw 16 that is accommodated in the interval portion 20 is hidden.

  According to the embodiment shown in FIG. 15, the heat exchange pipe 108 can be more reliably fixed. In addition, since the contact area between the heat exchange pipe 108 and the holding portion 14 (receiving portion 14a) becomes larger, the heat conduction efficiency is further improved.

  Further, in each of the above-described embodiments, one holding portion 14 that is continuous in the longitudinal direction is provided on one surface of the mounting plate 12, but it is not necessary to be limited to this. For example, as shown in FIG. 16, the plurality of holding portions 14 may be formed at predetermined intervals in the longitudinal direction of the mounting plate 12, that is, intermittently. Although the space | interval between the holding | maintenance parts 14 is not specifically limited, For example, it is 50-100 mm. Also in the embodiment shown in FIG. 16, the heat exchange pipe 108 can be reliably fixed. Moreover, when the holding | maintenance part 14 is formed intermittently in this way, material cost can be reduced compared with the case where the holding | maintenance part 14 is formed continuously in the longitudinal direction full length. However, it is desirable that the contact area between the heat exchange pipe 108 and the pipe holder 10 be as large as possible so that heat from the heat exchange pipe 108 is well transmitted to the pipe holder 10.

  Furthermore, in each of the above-described embodiments, the mounting plate 12 is formed with the groove 18 having a substantially V-shaped cross section as a mark for screwing, but the shape of the groove 18 is not particularly limited, The cross sectional view may be a substantially semicircular shape, a substantially square shape, or the like. In addition, the marked line is not necessarily limited to the groove 18 and may be a line by printing or writing, or may be provided by sticking a sticker with a line.

  Moreover, as shown in FIG. 17, the mark for screwing does not need to be limited to a marked line, and may be a depression 24 formed at a predetermined pitch.

  Further, the attachment portion to which the pipe holder 10 is attached is not necessarily the deck plate 106, and may be a concrete ceiling slab surface or another ceiling member such as a radiant ceiling panel. Or a wall, a floor, etc. may be sufficient.

  Further, in the embodiment shown in FIG. 1, the pipe holders 10 are arranged in the width direction orthogonal to the longitudinal direction, and the pipe holder 10 is attached with a heat exchange pipe 108 bent in a meandering manner and piped. However, the arrangement mode of the pipe holder 10 and the piping mode of the heat exchange pipe 108 are not particularly limited. For example, the pipe holder 10 may be arranged in a quadrangular spiral shape, and the heat exchange pipe 108 may be bent in a spiral shape corresponding to the pipe.

  Further, in the above-described embodiment, the mounting portion and the mounting plate 12 are screwed onto the groove (mark line) 18 of the mounting plate 12 by the screw 16 such as a tapping screw or a drill screw. For example, a bolt and a nut can be used. Although illustration is omitted, in order to attach the pipe holder 10 to the attachment portion using bolts and nuts, a screw hole is formed in advance at a corresponding position between the attachment portion and the pipe holder 10. The mounting portion and the pipe holder 10 are fixed by tightening a nut screwed into the bolt from the upper surface (back surface) of the mounting portion through the washer through the body portion of the bolt.

  Furthermore, in each of the above-described embodiments, the attachment portion and the pipe holder 10 are fixed only by screwing, but they may be screwed and adhesively bonded.

  It should be noted that the specific numerical values such as the dimensions described above are merely examples, and can be appropriately changed according to necessity such as product specifications.
