[0001] The present invention relates to a radiation panel and its mounting structure.

Background Art

[0002] Conventionally, in order to perform indoor heating and cooling, a radiation panel has been installed on the ceiling of a building. When a suspended ceiling is used for the ceiling of a building, the radiation panel can be attached between a plurality of long members (bar members) constituting the suspended ceiling.

[0003] For example, as disclosed in Patent Document 1, as shown in the perspective view of the main part seen from below in FIG. 11, a configuration in which the edge of a radiation panel 60 is supported on the upper surface of a horizontal plate portion 51 of a long member 50 having an inverted T-shaped cross section called a T-bar is disclosed as a conventional technique.

[0004] On the lower surface side of the radiation panel 60, a plurality of protrusions 61 having an arc-shaped cross section protruding downward are formed, and a groove portion $62$ is formed between adjacent protrusions 61. Since the lower end portion of the protrusion 61 abuts on the horizontal plate portion 51 of the long member 50, indoor illumination light hardly reaches the end portion of the groove portion 62 located above the horizontal plate portion 51, and there is a risk that the design property may be deteriorated due to the generation of a shadow S in this portion.

[0005] Therefore, in the invention of Patent Document 1, in order to prevent the illumination light from entering the end portion of the groove portion 62, a protrusion for closing the end portion of the groove portion 62 is provided on the long member 50 to prevent the generation of a shadow. However, since it is necessary to change the shape of the existing long member 50, there are cases where it is difficult to cope with it.

Modes for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a radiation panel according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line A-A of FIG. 1. The radiation panel 1 of the present embodiment is a heating and cooling radiation panel to be mounted on the ceiling inside a building. As shown in FIGS. 1 and 2, it includes a panel body 10, a protrusion 13 protruding from the lower surface side of the panel body 10, and pipes 20 and cross members 3 around the panel body 1 on the upper surface side.

[0017] The panel body 10 is configured by arranging a first spandrel 11 and a second spandrel 12 having a rectangular shape in plan view in parallel in the short side direction such that their edges overlap each other, and integrally connecting them with a plurality of cross members 30 extending in the parallel direction D. The first spandrel 11 and the second spandrel 12 may be respectively arranged at both ends of the panel body 10, and the number of each is not particularly limited as long as it is one or more. In the panel body 10 of the present embodiment, five first spandrels 11 are arranged continuously, and one second spandrel 12 is arranged adjacent thereto. The first spandrel 11 and the second spandrel 12 are made of a metal material having a high thermal conductivity such as aluminum, and are formed so that the cross section is wavy, whereby the protruding portions 13 having an arcuate cross section protruding to the lower surface side are arranged at equal intervals along the parallel direction D.

[0018] FIG. 3 is a cross-sectional view of the first spandrel 11. As shown in FIG. 3, first overlapping portions 11a and second overlapping portions 11b extending horizontally are respectively provided at both side edges in the short side direction of the first spandrel 11. The first overlapping portion 11a is formed so as to protrude outward in the short side direction from the protruding portion 13. On the other hand, the second overlapping portion 11b is formed so as to fold back inward in the short side direction from the protruding portion 13. The first overlapping portion 11a is located above the second overlapping portion 11b by the thickness of the first spandrel 11, and when a plurality of first spandrels 11 are arranged in parallel, the first overlapping portion 11a of one first spandrel 11 overlaps the upper surface of the second overlapping portion 11b of another first spandrel 11.

[0019] Engagement ribs 11c protruding to the upper surface side are provided over the entire length in the longitudinal direction on the first overlapping portion 11a and the second overlapping portion 11b, respectively. Each engagement rib 11c is formed so as to be adjacent in a state where the first overlapping portion 11a and the second overlapping portion 11b overlap each other, and the upper end portions are at substantially the same height position.

[0020] Figure 4 is a cross-sectional view of the second spandrel 12. As shown in Figure 4, the second spandrel 12 differs in shape from the first spandrel 11, with the first overlapping portion 12a and the second overlapping portion 12b formed on both short-side edges both extending horizontally outward from the projection 13 in the short-side direction. The first overlapping portion 12a and the second overlapping portion 12b are both located at the same height, and with the first overlapping portion 12a of the second spandrel 12 overlapping the upper surface of the second overlapping portion 11b of the first spandrel 11 shown in Figure 3, the lower ends of the projection 13 of the first spandrel 11 and the second spandrel 12 are formed to be approximately flush. Similar to the first and second overlapping portions 11a and 11b of the first spandrel 11, the first and second overlapping portions 12b are provided with engaging ribs 12c that protrude to the upper side along their entire longitudinal direction.

[0021] The pipe 20 is arranged so that its flow path is meandering, and a heat transfer fluid passes through its interior. The material of the pipe 20 is not particularly limited, but preferably examples include metal pipes made of aluminum or other materials, or double-layered or triple-layered pipes, which are lightweight and have a certain degree of rigidity. The straight portion of the pipe 20 is fitted into a groove-shaped fitting portion that is on the upper side of the projection 13 and is held in place by the panel body 10.

[0022] The crossbar members 30 can be made of, for example, channel steel, and multiple (three in this embodiment) are arranged at intervals along the longitudinal direction of the panel body 10 so that the U-shaped openings in the cross section face the panel body 10. Multiple engaging portions 31 and pressing portions 32 are formed in a notched shape at the lower part of the crossbar members 30. Each engaging portion 31 engages with the engaging ribs 11c, 12c of the panel body 10 and connects the first spandrels 11 to each other, or the first spandrel 11 and the second spandrel 12. The pressing portions 32 press the pipe 20 and fix it to the panel body 10. Of the three crossbar members 30, the crossbar members 30 arranged on both sides in the longitudinal direction of the panel body 10 are each provided with mounting hook portions 33 at both ends.

[0023] Figure 5 is an exploded perspective view showing a mounting structure for a radiant panel according to one embodiment of the present invention. The mounting structure for a radiant panel shown in Figure 5 comprises the radiant panel 1 described above and a plurality of elongated members 40 to which the radiant panel 1 is attached. The plurality of elongated members 40 are bar members of a system ceiling, suspended and supported from the ceiling inside the building by suspension bolts (not shown), and arranged in a grid pattern. In Figure 5, only the two elongated members 40 that support both sides of the radiant panel 10 in the short direction are shown.

[0024] The elongated member 40 comprises a flat web 41 arranged along the vertical direction, and a lower flange portion 42 and an upper flange portion 43 provided so as to protrude from the lower and upper parts of the web 41 on both sides in the thickness direction, respectively. The lower flange portion 42 is formed to have a larger overhang width than the upper flange portion 43.

[0025] While various cross-sectional shapes exist for the elongated members 40, the elongated member 40 in this embodiment is a so-called Y-bar, and is formed in a U-shape cross-section with the lower flange portion 42 branching into two and opening downwards. The radial panel 1 is supported on both sides in the short direction by multiple elongated members 40, with hook portions 33 provided on the crossbar members 30 engaging with the upper flange portion 43, which is the upper part of the elongated member 40.

[0026] Figure 6 is a cross-sectional view of the mounting structure of the radiant panel shown in Figure 5. As shown in Figure 6, both ends of the panel body 10 in the parallel direction D are formed by the first overlapping portion 11a of the first spandrel 11 and the second overlapping portion 12b of the second spandrel 12, respectively. When the radiant panel 1 is supported by a plurality of elongated members 40, both ends 11a and 12b of the panel body 10 in the parallel direction D are positioned above the lower flange portion 42 of the elongated members 40, and the lower end of the projection 13 becomes substantially flush with the lower end of the lower flange portion 42. As a result, when a plurality of radiant panels 1 are arranged continuously along the parallel direction D, the opening of the lower flange portion 42 blends in with the groove formed between adjacent projections 13 and becomes less conspicuous, thereby improving the aesthetic appearance.

[0027] Furthermore, in the relationship between the longitudinal end of the radiant panel 1 and the elongated member 40, the lower end of the projection 13 is substantially flush with the lower end of the lower flange portion 42 (i.e., the lower end of the elongated member 40), which reliably prevents the shadow S from being generated at the end of the groove portion 62, as in the conventional mounting structure shown in Figure 11. Therefore, this also enhances the aesthetic design of the mounting structure of the radiant panel 1.

[0028] The ends 11a and 12b of the panel body 10 in the parallel direction D may be in contact with the upper surface of the lower flange portion 42. However, since the radiant panel 1 is supported by the elongated member 40 via the hook portion 33, a small gap S may be formed between the ends 11a and 12b of the panel body 10 and the upper surface of the lower flange portion 42, as shown in Figure 7. With this configuration, in addition to the radiation of cold or warm air from the panel body 10, cold or warm air generated on the upper surface side of the panel body 10 can be supplied to the room through the gap S, thereby enhancing the heating and cooling effect. However, the ends 11a and 12b of the panel body 10 may be in close contact with the upper surface of the lower flange portion 42, in which case the radiant panel 1 may not have the hook portion 33.

[0029] The mounting structure of the radiation panel 1 in this embodiment includes a long member 40 having a lower flange portion 42 with a U-shaped cross-section called a Y-bar, as described above. However, existing long members 40 come in various cross-sectional shapes, and the radiation panel 1 of this embodiment can be easily adapted to long members 40 with different shapes.

[0030] Figure 8 is a cross-sectional view of a mounting structure for a radiant panel according to an application example of the present invention. The radiant panel 101 shown in Figure 8 is the same as the radiant panel 1 of this embodiment shown in Figure 2, etc., in which the second spandrel 12 provided at the other end is replaced with a third spandrel 112 at one end, and the other configurations are the same as the radiant panel 1 of this embodiment. In Figure 8, the same reference numerals are used for the same components as in Figure 2, etc., and detailed explanations are omitted. The elongated member 140 shown in Figure 8 is a bar material generally called a T-bar, and the lower flange portion 142 provided at the bottom of the web 141 arranged along the vertical direction is formed in a horizontally extending flat plate shape. The radiant panel 101 has projections 13 at both ends in the parallel direction D positioned above the lower flange portion 142.

[0031] Figure 9 is a cross-sectional view of the third spandrel 112 shown in Figure 8. As shown in Figure 9, the third spandrel 112 differs in shape from the first spandrel 11, with the first overlapping portion 112a and the second overlapping portion 112b formed on both edges in the short direction, both of which are folded back inward in the short direction from the projection 13 and extend horizontally. The first overlapping portion 112a and the second overlapping portion 112b are both located at the same height, and as shown in Figure 8, the first overlapping portion 11a of the first spandrel 11 overlaps the upper surface of the second overlapping portion 112b of the third spandrel 112, and the lower ends of the projection 13 of the first spandrel 11 and the second spandrel 12 are formed to be substantially flush. The first overlapping portion 112a and the second overlapping portion 112b are provided with engaging ribs 112c that protrude to the upper side along their entire length.

[0032] Thus, the radiant panel 1 of this embodiment can be attached to other long members 140 of different shapes simply by replacing the first spandrel 11 which constitutes a part of the panel body 10, and can be easily adapted to various construction sites at low cost.

[0033] In this embodiment, the projections 13 of the radiating panel 1 have an arc-shaped cross-section and are arranged at equal intervals along the parallel direction D. However, the cross-sectional shape of the projections 13 is not particularly limited. For example, as shown in Figure 10, a configuration in which multiple projections 13 with a cross-section extending linearly in the vertical direction are arranged at equal intervals may be used. In this case, the first spandrel 11 and the second spandrel 12 can be formed in a horizontal, flat plate shape. [Explanation of Symbols]
