Abstract

PURPOSE:To obtain panels for space heating which have a heat accumulation effect and, moreover, whose temperature can be elevated in a short period of time and made uniform. CONSTITUTION:Panels 1, 2 for space heating are constituted by dispersedly arranging heat transfer materials in panels made of mortar, which have, on their upper faces, grooves 1a, 2a where heat-generating members are disposed. Accordingly, a heat accumulation effect is produced by the mortar material and, moreover, heat generated from the heat-generating members disposed in the grooves can be efficiently transferred to the whole panels with the aid of heat transfer materials as heat transfer mediums. Therefore, the temperature of the whole panels is rapidly elevated up to a level of a heating temperature and, moreover, the temperature of the panels can be made uniform.

A permanent magnet or an electromagnet is arranged on the cover plate F side to cure the mortar (see FIG. 11). After curing, the cover plate F is opened and the cured product is taken out. Of course, the above-mentioned mortar is poured into the mold K closed by the cover plate F from a separate injection port, and curing is performed while applying vibration with the protrusion Fa facing downward, after which the cover plate F is opened and cured. You may take out the item.

The metal fibers mixed in the liquid mortar gradually move to the lid plate F side against the viscosity of the mortar due to the application of magnetic force in the curing process, and densely gather on the groove side surface. Further, a groove corresponding to the protrusion Fa is formed on the upper surface of the cured product, and the metal fibers located at the same portion are partially exposed on the inner surface of the groove.

Furthermore, the panel 31 can also be manufactured by the method shown in FIGS. First, a relatively long or continuous metal fiber is accommodated in the concave portion Ka of the form K so as to slightly rise (see FIG. 12). Then, the liquid mortar is poured almost completely into the mold K containing the metal fibers (see FIG. 13). Then
The opening of the mold 1 is closed by the lid plate F (see FIG. 4), and the opening of the mold 1 is closed by the lid plate F to cure the mortar (see FIG. 14). After curing, the cover plate F is opened and the cured product is taken out.

When the cover plate F is closed, the metal fibers in the mold K are pressed and deformed by the lower surface and the projections Fa, and the metal fibers on the groove surface side are concentrated. In addition, the protrusion Fa is formed on the upper surface of the cured product.
A groove corresponding to is formed, and the metal fibers located at the same portion are partially exposed on the inner surface of the groove.
