【Example】
Below, the exterior repair structure of the existing house which concerns on this invention using drawing is demonstrated in detail. 1 to 3 are schematic diagrams showing an example in which the exterior renovation structure A of an existing house according to the present invention is used for a wall and a roof of an existing house B. In FIGS. 2, a stud 3, a wood scraper 4, a lath material 5, a sheet-like material 6, and a mortar 7. The structure of the existing wall 1 includes a wall having a two-by-two (2 × 4) structure in addition to a large wall and a true wall.
[0006]
FIG. 3 is a schematic diagram showing an example in which this structure is used for the roof of the existing house B. Reference numeral 8 denotes an existing roof, which includes a main house 9, a rafter 10, a field board 11, and a colonial 12. Further, as the existing roof 8, a metal roof material can be used as a target for repair.
[0007]
1 to 3 show a metal siding material and a metal roof material in FIGS. 1 to 3, but also a cement plate, a calcium carbonate plate, a calcium silicate plate, a ceramic plate, a wood piece cement plate, a magnesium carbonate plate, etc. Glass fibers, whiskers, aramid fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, etc. mixed by extrusion molding, press molding, injection molding, paper making, etc., or various fibers in a cross shape Also included are three-dimensionally woven, steam-cured or fired products that have been impregnated with cement, clay, etc. into a panel shape, or sandwich panels in which synthetic resin foam is laminated between thin metal plates. Is. Of course, a dry board is not limited to the above example, and can be used arbitrarily.
[0008]
The base material E made of the thin metal plate D is a kind of iron, aluminum, copper, stainless steel, titanium or the like having a thickness of 1.6 mm or less, or an aluminum / zinc alloy plated steel plate, enameled steel plate, clad steel plate, laminated steel plate (vinyl chloride). Steel plates, etc.), sandwich steel plates (damping steel plates, etc.) (including color metal plates coated with various colors, of course) are roll-formed, press-formed, etc. to make steel frames, or aluminum alloys It can also be a material. Further, it is possible to combine these materials with plastic resin, FRP resin, etc., and to mix wood powder or the like into the resin. In the figure, lip groove steel is used as the base material E, but a metal thin film made of H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, equilateral angled steel, unequal angled angle steel, etc. A base material E made of a plate material D may be used.
[0009]
The cushion material F is generally commercially available such as polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt impregnated polyurethane, etc., and mainly used as a waterproof material, an airtight material, etc. Although useful as a function, soft polyurethane, vinyl chloride, polyethylene, polystyrene, urea foam, and the like can also be used. Further, as the cushion material F having fire resistance, rock wool felt or ceramic wool felt can also be used.
[0010]
Next, a construction example will be briefly described. In order to form a vertically-modified repair wall as shown in FIG. 1, the positions of the main pillar 2 and the inter-column 3 are confirmed on the existing wall 1, and the cushion material F indicated by a two-dot chain line is vertically attached to the corresponding position. To place. Next, the base material E is placed on the cushion material F, and the unevenness of the mortar 7 is eliminated and fixed by the elasticity of the cushion material F via the fixture 13. Next, although not shown, a starter is fixed to the base portion, and a new exterior material C as indicated by a one-dot chain line is sequentially applied from the base to the eaves via the fixture 13. 2 is constructed, the cushioning material F is arranged at regular intervals in the horizontal direction, and the base material E is placed and fixed horizontally on the cushioning material F as shown in the figure. Next, the step of sequentially connecting and fixing the vertically stretched new outer wall material C from the left and right sides to the other side may be repeated on the base material E. Further, FIG. 3 shows a case where the rafter 10 is confirmed on the existing roof 8 when used for a roof, and a cushion material F indicated by a two-dot chain line is arranged at a corresponding position. Next , the base material E is placed and interposed on the cushion material F arranged at regular intervals, and the unevenness of the colonial 12 is removed and fixed by the elasticity of the cushion material F via the fixture 13. In the case of the side roof of FIG. 3, although not shown, the starter is fixed to the eave portion, and a new exterior material C as shown by a one-dot chain line is attached via the fixture 13, and sequentially repeats from the eave toward the ridge. Can be installed.

【The invention's effect】
As described above, according to the exterior renovation structure of an existing house according to the present invention, (1) using a base material having a wall thickness of 1.6 mm or less makes handling (light, etc.) easy and requires skill. It can be constructed in a short period without using heavy machinery. (2) There is no need to interrupt residence. (3) Since the structure allows air circulation (air cycle) between the existing exterior and the new exterior, there is no condensation and excellent impact resistance. (4) By using the cushion material, even if the surface of the base material has irregularities, it can be absorbed and a wall body with a beautiful appearance can be formed. (5) Moisture from the existing wall surface or base portion can be prevented by the cushion material, and rusting of the base material can be suppressed. (6) If a cushioning material is previously attached to the base material, steps such as positioning can be omitted, and construction in one step is possible. (7) The unevenness of the existing house can be arranged at regular intervals, contacted with the base material, and removed and fixed by the elasticity of the cushioning material so that the bent tip of the base material hits the protruding rib. . There are features and effects.
