[0004]

In the above prior art,
In order to provide a plastic architectural decorative board with sufficient mechanical strength as an outer wall material, it is necessary to increase the wall thickness, but as a result, the weight increases and the handling is inconvenient. In addition, there is a problem that the heat insulation and the fire resistance are insufficient.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to realize a decorative board for building which is lightweight and has excellent heat insulation and fire resistance. is there.

[0006]

In order to achieve the above-mentioned object, a decorative plate for construction of the present invention comprises: a front wall having a block-shaped raised surface partitioned by a joint-like surface; A plastic outer shell having a hollow double-walled structure having a back wall facing the wall at an interval, and a connecting margin continuously provided on the periphery of the front wall and the back wall; And a foamed concrete filled in a hollow portion of the outer shell.

Further, a plurality of projections projecting toward the opposite side of the front wall are formed on the back wall at intervals.

Further, a plurality of protruding portions projecting toward the front wall side may be formed at a portion of the back wall facing the joint wind surface formed at the front wall, or may be recessed at the back wall toward the front wall. Form a concave rib.

In addition, a plastic outer shell having a hollow double-walled structure is integrally formed by extrusion molding and blow molding of a thermoplastic resin.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a decorative plate for construction according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, an architectural decorative plate P includes a front wall 1 and a back wall 2 opposed to each other at an interval, and a connecting wall (described later) provided on the periphery of the front wall 1 and the back wall 2. The foamed concrete 8 is filled into the hollow portion of a plastic outer shell having a hollow double-walled structure having margins 3 to 6 for use. The front wall 1 has a plurality of block-shaped raised surfaces 1a defined by jointed wind surfaces 1b, while the back wall 2 has a plurality of protruding portions 2b protruding from the opposite side of the front wall. Are formed at an interval from each other, and a concave rib 2a that is depressed toward the front wall side is formed.

In the present invention, the reason why the plurality of projecting portions 2b projecting from the back wall 2 to the side opposite to the front wall are formed at an interval from each other is that, as described later, the architectural decorative plate P is formed on the wall surface of the building. This is because, when pasting, a gap is formed between the wall and the like, and air is circulated through the gap to prevent dew condensation.

Therefore, a plurality of protruding portions 2b protruding to the opposite side of the front wall can be formed at arbitrary portions of the back wall 2, but in the present embodiment, they face the joint wind surface 1b of the back wall 2. Formed at the site.

Although the concave ribs 2a are formed for reinforcement, as in the present embodiment, if the distal end portion is shaped to abut against the back surface of the front wall 1a, the architectural decorative plate P The mechanical strength, such as the rigidity, is greater.

As shown in FIG. 2, a margin 3 connected to the upper edge portion (hereinafter referred to as an "upper margin") is formed on the back surface side of the joint wind surface 1b at the upper edge portion. Groove 3
a, a backing portion 3b bent outwardly following the fitting groove 3a, an extension 3d of the back wall 2 protruding outward in parallel with the backing portion 3b, a backing portion 3b and the back wall 2 And an end wall 3c that closes the tip of the extension 3d. The upper margin 3 is provided with a plurality of mounting holes 7 spaced apart from each other in the longitudinal direction. This mounting hole 7
Penetrates the backing portion 3 b of the upper margin 3, the foamed concrete 8, and the extension 3 d of the back wall 2.

In the present embodiment, a plurality of legs 3e projecting from the rear wall 2 to the side opposite to the front wall are provided at intervals from each other.

As shown in FIG. 2, a margin 4 (hereinafter, referred to as a "lower margin") continuously provided at the lower edge portion has an outer surface on the front wall side following the folded surface 1c of the raised surface 1a. Folded bent portion 4a and stepped portion 4 recessed toward the front wall formed on the back wall that forms a surface parallel to bent portion 4a.
b and an end wall 4c for closing the distal ends of the bent portion 4a and the step portion 4b.

A margin (hereinafter, referred to as a margin) connected to the right edge
"Right margin". As shown in FIG. 1C, 5 is a backing portion 5a in which the front wall side is bent outward following the folded surface 1c of the raised surface 1a, and the same surface as the top surface of the protruding portion 2b. Frame part 5 whose back wall side is bent so that
b and an end wall portion 5c for closing the front end portions of the backing portion 5a and the frame portion 5b.

The lower end of the right margin 5 is missing at least by a length corresponding to the protruding length (width) of the upper margin 3.

A margin (hereinafter, referred to as a margin) connected to the left edge
"Left margin". 6) The joint wind portion 6a bent outward so that the front wall side is flush with the joint wind surface 1b following the turnover surface of the raised surface 1a, and is flush with the top surface of the protruding portion 2b. The stepped portion 6b is recessed from the outer edge of the frame-shaped portion 2c whose back wall is bent toward the front wall side, and the joint wall portion 6a and the end wall portion 6c that closes the tip of the stepped portion 6b.

In the present invention, it is preferable that the plastic outer shell having the hollow double-walled structure is integrally formed by extrusion blow molding of a thermoplastic resin.

Regarding the function of the architectural decorative plate P of the present embodiment, a case where three architectural decorative plates P _{1 to} P ₃ shown in FIG. explain.

(1) First architectural decorative plate P on a wall or the like
₁ is positioned and fixed to the wall or the like by a fixing means such as a screw (not shown) using a mounting hole 7 provided in the upper margin 3.

(2) After the above (1), the second architectural decorative plate P ₂ is arranged above the _first architectural decorative plate P ₁ , and the lower margin 4 is placed on the _first architectural decorative plate P _1. After positioning fitted into the fitting groove 3a of the upper margin 3 architectural decorative panel P _1, by using the second piece of the mounting hole 7 of the upper margin 3 architectural decorative panel P ₂ bis It is fixed to the wall or the like by a fixing means such as.

Since the lower end of the right margin 5 is missing at least by a length corresponding to the protruding length (width) of the upper margin 3, the right end of the second architectural decorative board P ₂ is omitted. The margin 5 does not interfere with the margin 3 above the _first architectural decorative plate P1.

(3) After the above (2), the third architectural decorative plate P ₃ is arranged on the right side of the _first architectural decorative plate P ₁ , and then the first architectural decorative plate P 3 After positioning the third piece of architectural decorative panel P ₃ of the right margin 5 of the margin 6 of the left first sheet of architectural decorative panel P ₁ is slid overlapped towards _1, the top It is fixed to the wall surface or the like by a fixing means such as a screw using a mounting hole 7 of the margin 3.

[0027]

Since the present invention is configured as described above, the following effects can be obtained.

Since the hollow portion of the plastic outer shell having the hollow double-walled structure is filled with foamed concrete, it is lightweight and has excellent heat insulation and fire resistance.
