BACKGROUND ART Conventionally, radiant panels are installed on ceilings to cool and heat indoors. For example, Patent Document 1 describes a heat exchanger for a cooling and heating device in which a pipe through which a fluid passes and a frame member for connecting each panel are arranged on one side of a group of a plurality of panels arranged in parallel. A unit is disclosed. The frame member extends in a direction across each panel, and the frame member and each panel are elastically deformed and fit together at both ends of each panel in the width direction when the frame member and each panel are moved relative to each other in a direction in which they overlap each other. connected by mating connecting means.

More specifically, the connecting means comprises a claw piece formed on each panel and an engaging portion formed on the frame member, and between adjacent panels, a horizontal overlapping member connected to each claw piece. Each claw piece is configured to engage with the engaging portion in a state in which the portions overlap each other. A stepped portion is formed in the overlapped portion that becomes the upper side when overlapping each other, and positioning of each panel is performed by abutting the end surface of the overlapped portion on the lower side against the inner surface of the stepped portion.

Japanese Patent No. 5306843

In the above-described conventional connecting means, if a gap is formed between the end surface of the overlapped portion and the stepped portion during connection work, the gap is exposed downward, which may result in an unsightly appearance. For this reason, high dimensional accuracy is required for forming the stepped portion, and skill is required for the construction work.

In addition, by providing the stepped portion, the length of the claw piece is increased by the amount corresponding to the stepped portion, so there is a possibility that the material cost will increase when a large number of panels are used.

As shown in FIGS. 3 and 4, the ends of the first overlapped portion 23a and the second overlapped portion 23b are provided with a first projecting piece 15a and a second projecting piece 15a protruding in the orthogonal direction from one surface of each. A piece 15b is provided. The first protruding piece 15a and the second protruding piece 15b are formed in the shape of strip plates extending along the pipe receiving portion 13, and have hook portions 15a1 and 15b1 at their respective ends.

The plurality of panel bodies 4 arranged in parallel are arranged so that the second overlapping part 23b of the other adjacent panel body 4 overlaps with one surface of the first overlapping part 23a of one panel body 4, and The first projecting piece 15a and the second projecting piece 15b are arranged parallel to each other with a space therebetween. At the base end of the second projecting piece 15b, an intervening portion 12 protruding on the side opposite to the second overlapping portion 23b is provided so as to be flush with the other surface, which is the lower surface of the second overlapping portion 23b. It is In the intervening portion 12, when the first overlapped portion 23a and the second overlapped portion 23b are overlapped, the tip of the intervening portion 12 abuts on the first projecting piece 15a, thereby separating the first projecting piece 15a and the second projecting piece 15a. It is interposed between the piece 15b and maintains the interval between the first projecting piece 15a and the second projecting piece 15b.

As shown in FIGS. 3 and 4 , the frame material 5 can be made of channel steel, for example, and is arranged so that the opening having a U-shaped cross section faces the panel body 4 . A pair of side plates 5a (only one of the side plates is shown in FIGS. 3 and 4) forming the opening of each frame member 5 is formed with a notch-shaped engaging portion 26A. The engaging portion 26A has stepped portions 26a, 26a on both sides in the longitudinal direction of the frame member 5. Hooks of the first projecting piece 15a and the second projecting piece 15b are attached to the stepped portions 26a, 26a. The portions 15a1 and 15b1 are engaged with each other. A plurality of engaging portions 26A are formed according to the width of the panel body 4 in the parallel direction. Notched engagement portions 26B and 26C are formed at both ends of the frame member 5, respectively, and only one of the first projecting piece 15a and the second projecting piece 15b is connected to the engaging portions 26B and 26C. They engage with the stepped portions 26b and 26c, respectively.

A notched holding portion 30 for holding the pipe 3 accommodated in the pipe receiving portion 13 is formed between the engaging portions 26A. A pressing portion 30a is formed in the center of the holding portion 30, and the pressing portion 30a presses the linear portion 3a in a state where the first projecting piece 15a and the second projecting piece 15b are engaged with the engaging portion 26A. By doing so, the straight portion 3a is fixed. In this embodiment, the holding portion 30 is configured to directly contact and hold the straight portion 3a, but the holding member 30 may be configured to hold the straight portion 3a via a pressing member or the like. It is possible.

The upper portion of the frame member 5 is fixed to the joist 18 by screwing, welding, or the like. The method of supporting the joists 18 is not particularly limited. For example, as shown in FIG. Alternatively, as shown in FIG. 5(B), a ceiling slab (not shown) hanging bolts 20 suspend the ceiling joist 18. As shown in FIG. The frame member 5 does not necessarily have to be fixed to the joists 18 and may be fixed at other positions on the ceiling of the building.

As shown in the cross-sectional view of FIG. 6, the connection structure of the radiant panels having the above-described configuration is such that after the linear portion 3a is accommodated in the pipe receiving portion 13 of each panel body 4, each panel body 4 is attached to the right side of FIG. are pressed against the frame member 5 in order from the top to engage the first projecting piece 15a and the second projecting piece 15b with the engaging portions 26A and 26A, respectively. As a result, the first overlapped portion 23a of the panel body 4 attached later overlaps the second overlapped portion 23b of the panel body 4 attached to the frame member 5 first, and the first projecting piece 15a and the first overlapped portion 23a overlap each other. Interposed portion 12 is interposed between second projecting pieces 15b. The procedure for assembling the connecting structure of the radiation panel is not particularly limited. For example, as shown in the perspective view of FIG. are overlapped with each other, the first projecting piece 15a and the second projecting piece 15b may be engaged with the engaging portion 26A at the same time.

In the radiation panel connection structure of the present embodiment, the intervening portion 12 is between the first projecting piece 15a and the second projecting piece 15b on one surface side (upper surface side in FIG. 3) of the first overlapping portion 23a. Since the relative movement of each panel body 4 in the direction in which the first projecting piece 15a and the second projecting piece 15b approach each other is regulated, the other surface side of the first overlapping portion 23a On the lower surface side of FIG. 3, there is no possibility that gaps or the like at the stepped portion are generated as in the conventional art. Therefore, even if a slight dimensional error or an assembly error occurs, the aesthetic appearance between the panel bodies 4 is not impaired, and furthermore, since the material cost can be reduced by eliminating the stepped portion, the aesthetic appearance is improved. The connection structure of the radiation panels can be constructed at low cost.

The intervening portion 12 is not particularly limited as long as it can be interposed between the first protruding piece 15a and the second protruding piece 15b to keep the gap therebetween. For example, the intervening portion 12 of the present embodiment is provided at the proximal end portion of the second projecting piece 15b, but as shown in FIG. You may provide in the direction center part. The intervening portion 12 may be provided on the first projecting piece 15a as shown in FIG. 8(b) instead of being provided on the second projecting piece 15b.

Further, as shown in FIG. 8(c), it is also possible to provide a plurality of interposed portions 12-1 and 12-2 at intervals in the projecting direction of the second protruding piece 15b. The spacing between the first projecting piece 15a and the second projecting piece 15b can be reliably maintained at low cost. Each intervening portion 12-1, 12-2 does not necessarily have to be provided on either one of the first protruding piece 15a or the second protruding piece 15b, and as shown in FIG. The portion 12-1 may be provided on the first projecting piece 15a, and the other intervening portion 12-2 may be provided on the second projecting piece 15b.

The regulation of the relative movement of each panel body 4 may be performed on one surface side (upper surface side in FIG. 3) of the first overlapping portion 23a so as not to be seen from the inside of the room. is not limited to the above embodiments. For example, as shown in FIG. 9A, an engaging projection 16 may be provided on one surface of the first overlapped portion 23a, and the engaging projection 16 may engage with the second projecting piece 15b. can be done. As shown in FIG. 9B, the engagement projection 16 can be configured to engage with the second overlapped portion 23b by forming a concave portion 23b1 on the other surface of the second overlapped portion 23b. .
