Abstract

PROBLEM TO BE SOLVED: To form a wall body which does not bring dew drops, without skillful techniques, by laying a substrate chiefly constituted of a metallic plate having a specified thickness or thinner one through a cushion on an existing wall and fixing a new external facing material on the surface. SOLUTION: Cushion materials F such as vinyl chloride or the like eliminating the rugged face of mortar 7 with the elasticity are vertically arranged at the position corresponding to main columns 2 and studs 3 on an existing wall 1 constituted of wooden laths 4, laths 5, sheets 6, mortar 7, etc. And a substrate E made of a metallic thin plate D that iron, or aluminum or the like is rolled to make the thickness 1.6mm or thinner is laid thereon and fixed thereto through fixing tools 13. Then, a starter is fixed on a sill and the new external facing materials C are installed through the fixing tools 13 from the sill to the eaves one after another. The new external facing materials C are metallic siding materials or metallic roofing materials or the like. In this way, remodeling of walls can be executed without skillful techniques and suspension of habitation, in a short period. And a wall body excellent in shock-resistance can be formed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing an exterior renovation structure of an existing house according to the present invention. 1 to 3 are schematic diagrams showing an example in which an 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 FIG. 2, reference numeral 1 denotes an existing wall, which is composed of a main pillar 2, a stud 3, a wood lath 4, a lath material 5, a sheet 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.

FIG. 3 is a schematic diagram showing an example in which the present structure is used for the roof of an existing house B. Reference numeral 8 denotes an existing roof, which comprises a main house 9, a rafter 10, a field board 11, and a colonial 12. In addition, as the existing roof 8, a metal-based roof material can be used as a target for repair.

In FIGS. 1 to 3, the new exterior material C shows a metal siding material and a metal roof material. In addition, a cement plate, a calcium carbonate plate, a calcium silicate plate, a ceramic plate, a wood chip cement plate, a magnesium carbonate plate, etc. Alternatively, those obtained by mixing glass fibers, whiskers, aramid fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, and the like, and forming them by extrusion molding, press molding, injection molding, papermaking, or the like, or various fibers Woven into a cloth or three-dimensional shape, impregnated with cement, clay, etc. and molded into a panel shape, steam cured or fired, or a sandwich panel with a synthetic resin foam laminated between metal sheets Is also included. Of course, if it is a dry board, it can be used arbitrarily without being limited to the above example.

The base material E made of the metal sheet material D is made of iron, aluminum, copper, stainless steel having a thickness of 1.6 mm or less.
A kind of titanium, or an aluminum / zinc alloy-plated steel sheet, enameled steel sheet, clad steel sheet, laminated steel sheet (PVC steel sheet, etc.), sandwich steel sheet (damping steel sheet, etc.), etc. including)
Can be made into a steel frame material by roll forming, press forming or the like, or an aluminum alloy as a material. Further, it is possible to combine these materials with a plastic resin, an FRP resin or the like, or to mix wood powder or the like with the resin. In the figure, the base material E
The base material E is made of a metal sheet material D made of an H-section steel, an I-section steel, a grooved section steel, a lightweight grooved section steel, an equal angle section steel, an unequal angle section steel, etc. May be used.

The cushion material F is a commercially available material such as a polyvinyl chloride type, a chloroprene type, a chlorosulfonated polyethylene type, an ethylene propylene type, and an asphalt-impregnated polyurethane type. Although useful as a function of the material and the like, soft polyurethane, vinyl chloride, polyethylene, polystyrene, urea foam and the like can also be used. Rock wool felt and ceramic wool felt can also be used as the cushioning material F having fire resistance.

Next, an example of construction will be briefly described. Now, in order to form a vertically renovated wall as shown in FIG. 1, the positions of the main pillar 2 and the stud 3 are confirmed on the existing wall 1, and the cushion material F indicated by a two-dot chain line is vertically positioned at 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 shown by a dashed line is sequentially applied from the base to the eaves via the fixture 13. When constructing the vertically renovated wall shown in FIG. 2, the cushion members F are arranged at regular intervals in the horizontal direction, and the base material E is placed and fixed horizontally on the cushion members F as shown in the figure. Next, the step of sequentially connecting and fixing the vertically extending new outer wall material C from one side to the other side on the base material E may be repeatedly performed. Further, FIG. 3 shows a case where the conventional roof 8 is used for a roof.
The rafter 10 is confirmed on the upper side, and the cushion material F indicated by a two-dot chain line is arranged at a corresponding position. Next, the base material E is placed on the cushion material F, and the unevenness of the colonial 12 is eliminated and fixed by the elasticity of the cushion material F via the fixture 13. In the case of the horizontal roof of FIG. 3, a starter is fixed to the eaves, not shown, and a new exterior material C as shown by a dashed line is attached via the fixture 13, and the roof is sequentially repeated from the eaves to the ridge. It is only necessary to construct it.

[0019]

As described above, according to the exterior renovation structure of an existing house according to the present invention, by using a base material having a thickness of 1.6 mm or less, handling becomes easy (light, etc.), and skill is improved. It can be installed in a short period of time without using heavy equipment. There is no need to suspend your residence. Since the structure allows air circulation (air cycle) between the existing exterior and the new exterior, there is no condensation and excellent impact resistance. By using the cushion material, even if there are irregularities on the surface of the base material, it can be absorbed and a beautifully-appearing wall can be formed. Moisture from the existing wall surface or base can be prevented by the cushion material, and rusting of the base material can be suppressed. If a cushioning material is attached to the base material in advance, the steps such as positioning can be omitted, and the work can be performed in one step. There are features and effects such as.
