Abstract: A plate block includes a decorative plate which includes a substratum and a face veneer joined to the substratum by adhesive means. The substratum has a front face and a rear face with inclined edge portions disposed between the front face and the rear face such that the rear face is larger than the front face. The face veneer is joined to the front face and to the edge portions. A base plate is disposed in spaced parallel relationship relative to the decorative plate, and an intermediate member is disposed between the base plate and the decorative plate with the base plate having at least one edge portion projecting beyond an edge of the decorative plate to facilitate assembly of a plurality of plate blocks in juxtaposed array.

Abstract: A plurality of structural unit bodies are utilized to construct by suitably assembling the unit bodies. Each structural unit body comprises an outer flange and an inner flange extending from one end edge and the other end edge respectively of a box-shaped frame. A stuffed box is secured to the surface of the inner flange and the stuffed box is in the form of a flat box made of a dampproof material. The stuffed box is covered on the outside with a metal net-like material and has disposed therein a pipe capable of passing fluid therethrough. The box is stuffed with noncombustible materials. The upper portion of the middle section of the frame, the inside flange surface and the entire surface of the stuffed box is plastered or covered with mortar whereby there is formed a circumferential groove between the outer flange and the underside of the mortar.

Abstract: A structural timber is made up of an inorganic fiber felt like material, a dampproof sheet like a material, and metal net like material laid in order over a sheet like base material and stapled together whereby the staples tightly hold the materials together.

Abstract: A structural unit body comprises an outer flange extending outwardly from the edge of a box-like frame plate and an inner flange extending inwardly from the other edge. A stuffed box is secured by anchoring means to the inner flange such stuffed box being made of dampproof material covered with a metal net and stuffed with noncombustible materials of mineral or inorganic fibers. Cement mortar is applied to the frame plate, inner flange and to the metal net of the stuffed box and a circumferential groove is formed between the outer flange and the underside of the cement mortar.
