Abstract

PROBLEM TO BE SOLVED: To easily produce a plastic wall member for housing that tiles are stuck on a wall base board having a hollow double-wall structure and easily construct a tile wall, by inserting tiles in a split mold and treating them through blow molding. SOLUTION: Plastic tiles 6 are stuck on the recesses of the front wall 8 of a plastic wall base board 5 and joints 9 are integrally formed to make a hollow double-wall structure with the tabular rear wall 11 and the peripheral walls 12, in the wall member 2 for housing. Regarding to the wall member 2, tiles 6 are temporarily fixed to the cavity of a split mold through an interposing member and a pressurized fluid is led in a parison to produce a thermosetting plastic through the blow molding. In this time, if a heat-sensitive adhesive layer is formed at the rear face of the tiles 6, the adhesive strength can be increased. Therefore, a light-weight tile wall member 2 for housing, excellent in sound-insulation and heat-insulation can be easily produced and a tile-interior wall such as a bathroom or a tile-exterior wall can be easily constructed by using the wall members.

FIG. 3 shows a blow molding mode according to the method for manufacturing a wall material for a house according to the present invention, in which a tile is inserted into one of the divided molds and a parison is arranged between the divided molds. FIG. 4 is an enlarged cross-sectional view of a portion surrounded by a two-dot chain line circle in FIG. 3, and FIG. 5 is a cross-sectional view of a process of blow molding after completion of mold closing from the state of FIG.

In FIG. 1, reference numeral 1 denotes a bathroom of a house, and a wall of the bathroom 1 is constructed of a wall material 2 for a house according to the present invention. 3 is a bathtub and 4 is a window. The house wall material 2 is obtained by sticking a large number of tiles 6 on the surface of a wall substrate 5, and a required number of house wall materials are provided between a plurality of pillars 7 located behind the wall of the bathroom 1. The walls of the bathroom 1 are constructed by sequentially lifting the walls 2.

In the wall material 2 for a house according to the present invention, the wall substrate 5 is made of plastic, and as shown in FIG.
The wall substrate 5 has a hollow double wall structure, and a large number of tiles 6 are stuck on the surface of the front wall 8 in an orderly manner. Joints 9 are formed between the many tiles 6, and the joints 9 are formed integrally with the front wall 8 of the wall substrate 5 standing up in the surface direction. That is, the joint 9 has a height lower than the thickness of the tile 6, and the joint 9 forms a concave portion 10 surrounding the tile 6. The back wall 11 of the wall substrate 5 has a flat plate shape,
The periphery of the front wall 8 and the back wall 11 is integrally formed by the peripheral wall 12 so as to have a closed hollow portion. In addition,
The wall substrate 5 may not necessarily have a hollow double wall structure.

The surface of the tile 6 can have any color, and the surface can be made glossy. If the back surface of the tile 6 is an uneven surface, the bonding strength of the wall substrate 2 to the front wall 8 can be increased.

The means for attaching the tile 6 to the front wall 8 of the wall substrate 5 includes not only physical fixing by surrounding the periphery of the tile 6 with the concave portion 10 but also bonding with an adhesive, particularly a heat-sensitive adhesive.

The housing wall material 2 according to the present invention is manufactured by blow molding as shown in FIGS. FIG.
5 to 13, reference numerals 13 and 14 denote divided molds and reference numerals 15 and 1
6 is a cavity, 17 is an extrusion head, and 18 is a parison.

In blow molding the wall material 2 for a house according to the present invention, as shown in FIG. 3, an intervening member 19 is temporarily fixed to the cavity 16 of the split mold 14 and
The tiles 6 are arranged in advance in the recesses 20 for holding the respective tiles 6 so that the surfaces thereof face the mold side and are temporarily fixed,
The tile 6 is inserted into the split mold 14. Interposed member 1
Numeral 9 is for holding the tiles 6 at regular intervals. Then, a parison 18 is arranged between the split molds 13 and 14 from the extrusion head 17.

As shown in detail in FIG. 4, the interposition member 19 has a projection 21 for forming the joint 9 between recesses 20 for holding the respective tiles 6. Adhesive means such as attaching an adhesive to both surfaces of the intervening member 19 is provided, and the intervening member 19 is temporarily fixed to the cavity 16 and the tile 6 is temporarily fixed. Note that a suction cup (not shown) may be used as a means for temporarily fixing the tile 6 to the interposition member 19.

Since the wall substrate 5 and the joints 9 of the housing wall material 2 according to the present invention are made of plastic, it is possible to obtain a tile interior wall or a tile exterior wall of a required size and light weight. In addition, those having excellent earthquake resistance and good coloring can be easily obtained. Further, since the wall substrate 5 has a hollow double-wall structure, it has excellent sound insulation properties and heat insulation properties.

From the embodiment shown in FIG. 3, the mold 1 shown in FIG.
When the blow molding is performed by closing the fins 3 and 14 and introducing a pressurized fluid into the parison 18, the cavities 1
The wall material 2 for a house along the shape of 5, 16 is formed,
Tiles 6 are fixed to the surface of the front wall 8 of the wall substrate 5 having the hollow double-wall structure, and joints 9 formed by the front wall 8 bulging in the surface direction surround the tiles 6 between the tiles 6. It is formed as follows. For this reason, the tile 6 adhered to the wall substrate 5 is securely held by the joints 9 surrounding the tile 6, so that peeling over time hardly occurs. The joint 9 is formed at a certain height lower than the thickness of the tile 6 by the protrusion 21 of the interposition member 19.

In the case where the back surface of the tile 6 has an uneven surface,
At the time of blow molding, the adhesion strength of the wall substrate 5 to the front wall 8 is increased, and peeling over time hardly occurs. Further, by providing a heat-sensitive adhesive layer on the back surface of the tile 6 and bonding the tile 6 to the front wall 8 of the wall substrate 5 by adhesion at the time of blow molding, the bonding strength can be improved. it can.

In the present invention, the thermoplastic plastic constituting the wall substrate 5 and the tile 6 may be any one which can be blow-molded, and may be polyethylene resin, polypropylene resin, ethylene-vinyl acetate copolymer, vinyl chloride resin, or the like. Engineering plastics such as ABS resin (acrylonitrile-styrene-butadiene resin), polyamide resin, polystyrene resin, polyester resin, polycarbonate resin and modified polyphenylene ether are preferable.

In the illustrated embodiment, an example is shown in which the housing wall material 2 according to the present invention is used for the wall of the bathroom 1 of a house, but it is used as a tile interior wall or a tile exterior wall of other houses. Of course, it is highly versatile, as it can be used as it is as a tile wall material other than a wall material for a house.

[0029]

According to the wall material for a house according to the present invention, the base wall constituting the tile interior wall or the exterior wall is made of plastic and the tiles are stuck together when the wall substrate constituting the base wall is formed. Since it forms a joint that is integral with the tile, it is easy to obtain a tile interior wall or tile exterior wall of the required size, and it is lightweight, has excellent earthquake resistance, has good coloring, and has sound insulation. Excellent in heat resistance and heat insulation.

According to the method for manufacturing a wall material for a house according to the present invention, a tile is inserted into a split mold and blow-molded, so that a wall material for a house having excellent functions as described above can be easily manufactured. can do.
