  • FIGS. 1 and 2 a rectangular frame body 1 is provided on which there is fixed a slightly smaller but similar frame body 2 to form a stepped frame body 3 having a step 17 formed with the frame body 2.
  • the stepped frame body 3 is open on the inside and forms an opening portion 16 which is provided with a rail 15 for reinforcement as required.
  • FIG. 1 Alternatively it is also possibly to practice the present invention, as shown in FIG. 1
  • a frame body 1 and a smaller frame body 2 having an opening portion inside together utilizing such materials as metal, wood, plastic, lightweight concrete, and inorganic board, to thereby form an incorporated block with the latter being used, as a stepped frame body 18 having a step 17 formed with the smaller frame body 2.
  • a stepped frame body 18 having a step 17 formed with the smaller frame body 2.
  • FIG. 3 there is disposed over the surface of a rectangular planar body 4 which is slightly larger than the smaller frame body 2 a felt-like or mat-like body 5 made of mineral or inorganic fiber, a dampproof planar body 6, and a metallic net body 7 in succession to form a structural body or assembly unit 9 held together by metallic fasteners 8.
  • This structural body 9 is placed and secured on the small frame body 2 of the stepped frame body 3 (FIG.
  • a'structural unit body 10 by fixing or securing with nails or glue as shown in FIGS. 4 and 5.
  • a circumferential groove 11 is formed which is as wide as the thickness of the smaller frame body 2 or the stepped portion 17.
  • material such as mortar 12 may be applied and fixed to the metallic net body 7 of the structural body 9, whereby a finished single block 13 is obtained. In such a case there will be formed a narrow circumferential groove 14.
  • the stepped body 3 as it relates .to the structure of this invention is so builtup or arranged that a plurality of base plates are assembled in the form of a frame or rail and a rectangular frame body 1 and a smaller similar frame body 2 having the opening 16 are fixed together.
  • the base plate may be a veneer or plywood.
  • the frame body 1 and the smaller frame body 2 may be made as an integrated unit with the rail portion 15 formed into an incorporated block to thereby define a stepped frame body 18 having an opening portion 16.
  • the planar body 4 is made of wood, synthetic wood, or the like, and preferably is subjected to treatment with a preservative. As may be required in the construction, the planar body 4 may be provided inside with an opening.
  • the felt-like mineral or inorganic fiber body 5 is formed of fibers such as glass wool, asbestos, slag wool, and rock wool, separately or in mixtures thereof, or mixed with non-combustible synthetic fibers, the arrangement being such that there are voids between fibers.
  • a body as the fiber body 5 may take the form of sheet or mat.
  • the fiber body 5 is heatresistant, protects against tire and effectively insulates against sound and heat.
  • materials such as asphalt felt, thick paper, or various kinds of roofing materials are used.
  • the metallic net body 7 is a net-like material in the form of metal lath or wire lath. Metal lath is mostly manufactured by expanding perforated iron sheet and wire lath is mostly a net made of iron wire or chains.
  • the metallic fasteners 8 are forced across the intersection of the metallic net 7 through the dampproof planar body 6, the inorganic fiber felt-like body 5, and the planar body 4 in succession, thereby fastening and tightening all of the material members together.
  • the positions of binding by the fasteners 8 are so chosen that the fastening will be effective physically and functionally, while presenting a good appearance.
  • the thus obtained structural body 9 of the hereinabove described prevents penetration of moisture, and is heat-preserving and heat-insulating. That is, the dampproof planar body 6 interrupts or presents the effect of dampness or moisture from the outer side of the structural body and also from the spaces between or at the back-side of the planar body.
  • the inorganic fiber felt-like body 5 reduces the dampness in the air evolved in or at the side of the dampproof planar body 6 as a result of capillary phenomenon, atomization and vaporization phenomena by the action of the air contained in the fibers.
  • the dampproof planar body 6 and inorganic fiber felt-like body 5 which are fastened as described above by the metallic fasteners 8 become uneven, sinking or rising locally, because of the fastening forces resulting from the metallic fasteners 8 and thereby develop an elasticity. This expanding or contracting effect accelerates vaporization of moisture and, further, provides partition walls to vaporize the dampness uniformly.
  • the structural body 9 all members are fastened in succession as heretofore described and accordingly, the structural body 9 is elastic and air-permeating and also sound-insulating, and heatinsulating due to the presence of the inorganic fiber felt-like body.
  • the stability of the frame body and associated bodies is increased.
  • Such bodies are easy to apply and use and, accordingly, are suitable for structural material in the field of building and construction, making possible construction of buildings having good living environmental conditions.
  • the block is durable since the metallic net serves as a reinforcing member.
  • FIGS. 7a, 7b, 7c, and 8 The heretofore structural unit body of the present invention is applied as shown in the embodiment in FIGS. 7a, 7b, 7c, and 8.
  • FIG. 7a shows an example in which an outer wall surface of a column 23 is composed of connected structural unit bodies 10 constructed on the outside with metallic net bodies.
  • FIG. 7b shows an example in which the inner wall surface is composed of structural unit bodies 13 finished on the outside with mortar.
  • the floor face in FIG. 70 is shown in a horizontal disposition.
  • the frame body 1 of the structural unit body 10 or 13 is fixed by nailing as indicated at 32, to a beam 24 mounted horizontally at proper intervals on a column 23 standing vertically on a sill 22 placed on a foundation of concrete 2] on the ground 20.
  • the outer wall surface in FIG. 7a and the inner wall surface in FIG. 7b may be selected for either or both interchangeably and the structural unit body 10 or 13 may be used in combination as desired.
  • the unit body is fixed to the beam 24, and when the succeeding unit body is mounted, it is connected by fitting a connection plate 25 (FIG. 9) into the circumferential groove 14.
  • the connection plate 25 is a narrow and long planar body 30 covered with lath, but alternatively such a connection body may be replaced by a suitable elongated planar body.
  • the connecting plate 25 need only be inserted securely into the circumferential groove 14 and firmly connected therewith.
  • the floor face shown in FIG. 7c likewise need only be assembled in a similar manner. As shown in FIG.
  • each structural unit body adjacent to another structural unit body forms a straight line interval indentation 33 in the construction of each wall surface.
  • the construction is effected in such a manner it is preferable to provide a construction in the manner shown in FIGS. 70, 7b and 70, whereby the connection plate 25 shown in FIG. 9 or the insertion plate 26 shown in FIG. 10 is inserted into the interval 33.
