Description

The present invention relates to a connecting structure of radiant panels, and more particularly to a connecting structure of radiant panels provided on the ceiling of a building to cool or heat a room.

In order to heat and cool the room, it has been conventionally practiced to install a radiant panel on the ceiling. For example, in Patent Document 1, heat exchange for a heating / cooling device is provided in which a pipe through which a fluid passes and a frame material for connecting each panel are arranged on one side of a group of a plurality of panels arranged in parallel. The unit is disclosed. The frame material extends in a direction that crosses each panel, and the frame material and each panel are elastically deformed and fitted when the frame material and each panel are moved relative to each other at both ends in the width direction of each panel. They are connected by matching connecting means.

In the heat exchange unit disclosed in Patent Document 1, if the dimensional accuracy of the connecting structure is low, it becomes difficult to properly fit the frame material to the panel, and the construction work may be complicated. In addition, since the frame material is indispensable for connecting the panels, the material cost may increase.

On the other hand, Patent Document 2 discloses a radiation panel in which a mounting member having a holder portion for supporting a pipe through which a fluid passes is fixed to a substrate with an adhesive. In this radiant panel, a large number of fine recesses are formed on the adhesive surface of the substrate and the mounting member, and the adhesive enters the recesses to improve the adhesiveness and heat transfer property.

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