Abstract

A wall materials bracket comprises a base piece 11, a catching piece 12, a spacing piece 13 and a holding piece 14, and further includes a leaning means for leaning an insulation put on the catching piece 12 against a wall substrate. For example, the leaning means is constructed with the upper half 111 of the upper part 110 of the base piece 11, a slope 113 in the lower half 112 of the upper part 110, and a cavity 132 and bosses (133) in the upper part 130 of the spacing piece 13.

Claims

1. A wall materials bracket for fixing an insulation and an external wall board as wall materials on a wall substrate, comprising:

a flat-shaped base piece that is fixed on the outer surface of said wall substrate;

a flat-shaped catching piece that is formed to protrude outward from between the upper and lower parts of said base piece, said catching piece holding the bottom or top end of at least one insulation to restrict its downward or upward movement;

a spacing piece that is interposed between said at least one insulation and at least one external wall board to form an air layer between them, said spacing piece being formed at the tip of said catching piece so as to face the upper and lower parts of said base piece, said spacing piece sandwiching said at least one insulation between the base piece and the spacing piece;

a holding piece that is formed outside of said spacing piece, said holding piece holding said at least one external wall board to restrict its outward and inward movement as well as its downward or upward movement;

wherein said wall materials bracket includes a leaning means for leaning the insulation put on said catching piece against said wall substrate.

2. The wall materials bracket of claim 1, wherein said holding piece is formed outside of said spacing piece and below said catching piece.

3. The wall materials bracket of claim 1, wherein a butt edge is formed at right or left side end of the wall materials bracket as seen from said holding piece side, said butt edge inclining at an angle corresponding to a reentrant corner of said wall substrate.

4. The wall materials bracket of claim 1, wherein a butt edge is formed at right or left side end of the wall materials bracket as seen from said holding piece side, said butt edge inclining at an angle corresponding to a salient corner of said wall substrate.

5. An insulating wall structure constructed by fixing the wall materials on the wall substrate with the wall materials bracket of claim 3, comprising:

at least two said wall materials brackets that are respectively fixed on the two outer surfaces forming the reentrant corner of said wall substrate with their butt edges butted together;

at least two said insulations that are butted together and held with the catching pieces of said wall materials brackets;

at least two said external wall boards that are held with the holding pieces of said wall materials brackets; and

airtight tape that seals between said insulations butted together.

6. An insulating wall structure constructed by fixing the wall materials on the wall substrate with the wall materials bracket of claim 4, comprising:

at least two said wall materials brackets that are respectively fixed on the two outer surfaces forming the salient corner of said wall substrate with their butt edges butted together;

at least two said insulations that are butted together and held with the catching pieces of said wall materials brackets;

at least one said external wall board that is held with the holding pieces of said wall materials brackets; and

airtight tape that seals between said insulations butted together.

7. An insulating wall structure constructed by fixing the wall materials on the wall substrate with the wall materials bracket of claim 1, comprising:

said wall materials brackets that are fixed and arranged in at least one row on the outer surface of said wall substrate;

said insulations that are fixed and arranged side by side with said wall materials brackets;

said external wall boards that are fixed and arranged side by side with said wall materials brackets;

airtight tape that seals between said insulations neighboring each other; and

waterproof materials that waterproofs between said external wall boards neighboring each other;

wherein said insulation has a width substantially equal to one or more times width of said external wall board.

8. An insulating wall structure constructed by fixing the wall materials on the wall substrate with the wall materials bracket of claim 1, including at least two said insulations butted together, one of them having a transformable tongue which is pressed against a butt end of another of them.

9. An insulating wall structure constructed by fixing the wall materials on the wall substrate with the wall materials bracket of claim 1, comprising:

at least one said insulation;

at least one said wall materials bracket that is fixed on the outer surface of said wall substrate, said wall materials bracket holding said insulation with the holding piece to form an air layer between them; and

at least one said external wall board that is held with the holding piece of said wall materials bracket;

wherein;

the air layer between said wall substrate and said insulation is sealed to function as an airtight layer;

the air layer between said insulation and said external wall board is connected to the open air to function as a vent layer.
