BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiant panel connection structure, and more particularly, to a radiant panel connection structure that is installed on the ceiling of a building to cool or heat a room.

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.

In the heat exchange unit disclosed in Patent Document 1, if the dimensional accuracy of the connection structure is low, it becomes difficult to correctly fit the frame member to the panel, and there is a risk that the construction work will be complicated. In addition, since a frame member is essential for connecting the panels, there is a possibility that the material cost will be high.

On the other hand, Patent Literature 2 discloses a radiation panel in which a mounting member having a holder portion that supports a pipe through which fluid passes is fixed to a substrate with an adhesive. In this radiation panel, a large number of fine recesses are formed in the bonding surfaces of the substrate and the mounting member, and the adhesive penetrates into the recesses to improve adhesion and heat transfer.

However, it is difficult to reliably bond all of the many mounting members to the substrate, and there is room for further improvement from the viewpoint of improving workability and durability.
