2. Description of the Related Art When a concrete or mortar is used in a building or a structure to form a plate-like body such as a wall for various purposes, a panel for construction or the like used as a base material thereof is disclosed in, for example, Japanese Unexamined Patent Publication The thing disclosed by the 5-124123 gazette is known. This panel for construction or the like is configured as shown in FIGS. FIG.
In -5, 21 is a three-dimensional wire mesh that serves as a reinforced material such as mortar. This is a pair of grid wire meshes 22 and 23 formed by welding the intersections of metal wires arranged vertically and horizontally at intervals. They are arranged in parallel and face each other, and their wire mesh 22, 23
Are connected to each other by a connecting metal wire 24 which is installed and welded to them. Reference numeral 25 denotes a foam polystyrene panel which is embedded in a portion of the three-dimensional wire net 21 on the grid wire net 23 side and is attached to one side of the grid wire net 23.

As shown in FIG. 4, the lattice metal wire 23 side is embedded in the foamed polystyrene panel 25 by inserting the whole three-dimensional wire mesh 21 into the molds 26 and 27 for molding the foamed polystyrene panel 25. , And the vertical and horizontal metal wires forming the grid-shaped wire mesh 22 and the joint wire 24 welded thereto are inserted into the groove 28 provided in the mold 26, and then the mold is inserted into the groove 28. Clamp 26 and 27. Then, the foamed polystyrene beads that have been pre-foamed to a size that does not enter the groove 28 are supplied to the cavity 30 by the feeder 29 in a required amount, and the foamed polystyrene beads are heated and foamed by steam to form the foamed polystyrene panel 25. Thus, the expanded polystyrene is prevented from entering the recessed groove 28, and the portion of the cavity 30 located on the side of the lattice-shaped mesh 23 is embedded in the molded expanded polystyrene panel 25.

As mentioned above, the expanded polystyrene panel
The panel for construction, in which one side of the three-dimensional wire mesh 21 is embedded and fixed in 25, is a place where it is difficult to apply mortar from both sides of the expanded polystyrene panel 25, or the expanded polystyrene panel 25 is discarded. It is a panel used when the wall body is constructed in a place that can be placed in the place after construction as a formwork. That is, for example, as shown in FIG.
A mortar layer 31 is formed on the surface of the expanded polystyrene panel 21 having a protruding side on the 22 side by spraying or other suitable means, and the portion on the side of the lattice-shaped wire mesh 22 is embedded as a reinforced material in this mortar layer 31 to form a wall body. Make up. 32 is a finishing mortar layer formed on the surface of the mortar layer 31. As mentioned above,
The mortar layer 31 is embedded in the mortar layer 31 to reinforce the mortar layer 31 at a portion thereof, and the three-dimensional metal net 21 integrally joins the foam polystyrene panel 25 and the mortar layer 31 to a building wall or the like. It constitutes a plate body of. The expanded polystyrene panel 25 has a heat insulating effect, contributes to the weight reduction of the building board, and can eliminate the need for a formwork.

[0005]

In the conventional panel for construction or the like, the molds 26, 27 for molding the foamed polystyrene panel 25 have a complicated structure, and the molds 26, 27 have a three-dimensional shape. Since it is necessary to insert the wire net 21 and the labor required for it is increased, there is a problem such as an increase in cost. Then, when the foamed polystyrene panel 25 is molded by the molds 26, 27, the lattice-shaped metal mesh 23 of the three-dimensional metal mesh 21 is used.
The expanded polystyrene beads that have been pre-expanded in the recessed groove 28 in which the side is inserted are contained, and in order to prevent the foamed polystyrene wall corresponding to the recessed groove 28 from being formed on one side of the expanded polystyrene panel 25, the recessed groove is formed. There is a need to use expanded polystyrene beads that have been pre-expanded to a diameter greater than 28 width.

If the difference between the size of the pre-expanded expanded polystyrene beads and the width of the groove 28 is small, the pressure when the pre-expanded expanded polystyrene beads are heat-expanded is adjusted to one of them. There is a problem that there is a great possibility that the portion will enter the concave groove 28. Thus, when the polystyrene groove enters the groove 28, the polystyrene wall corresponding to the groove 28 is formed on one side of the polystyrene foam panel 25,
The surface of the foamed polystyrene panel 25, and the distance between the vertical and horizontal metal wires forming the lattice-shaped metal mesh 22 protruding therefrom, the styrene wall is small or eliminated,
There is a problem that the bonding force between the mortar layer 31 and the portion of the three-dimensional wire net 21 protruding from the expanded polystyrene panel 25 is reduced.

The present invention is intended to solve the above-mentioned problems, and it is possible to reduce the labor required for embedding a part of a three-dimensional wire mesh in a foamed plastic panel and to reduce the cost. Another object of the present invention is to obtain a panel for construction or the like in which the foamed plastic is not likely to protrude on the surface of the foamed plastic panel on which the lattice-shaped wire mesh protrudes.

DISCLOSURE OF THE INVENTION In a panel for construction or the like of the present invention, a pair of grid-like wire nets formed by welding intersections of metal wires arranged vertically and horizontally are arranged parallel to each other and spaced apart in parallel. The pair of lattice-shaped metal nets are connected to each other by connecting metal wires welded in an erected manner to form a three-dimensional metal net, and one of the three-dimensional metal nets is embedded in a foam plastic panel. , In a panel for construction or the like in which the other side of the lattice-shaped wire mesh is projected from the foamed plastic panel, the three-dimensional wire mesh is heated to overlap one of the lattice-shaped wire meshes on the foamed plastic panel, and the heat of the lattice-shaped wire mesh is used. The foamed plastic panel was heated to form concave grooves corresponding to the metal wires forming the grid-shaped wire mesh on the foamed plastic panel, and at the same time, one grid-shaped wire mesh side portion was embedded in the groove. And wherein the door.

The three-dimensional wire mesh is formed of soft steel wire, hard steel wire, iron wire, or the like. As the plastic constituting the foamed plastic panel, polystyrene, rigid polyurethane, polyethylene and other plastics usable as panels for construction are selected and used. The heating temperature of the three-dimensional wire mesh when embedding it in the foamed plastic panel is set to a temperature at which the foamed plastic panel can be softened or melted to a width approximately the same as the diameter of the metal wires that make up the latticed wire mesh. is there.

For example, the melting point of polystyrene is 11 degrees Celsius.
Although it is 0 degree, expanded polystyrene has many air bubbles inside. Therefore, the foamed polystyrene loses its heat and shrinks before being melted when heated. Therefore, when the foamed plastic panel is made of polystyrene, the latticed wire mesh of the three-dimensional wire mesh heated to about 105 to 109 degrees Celsius, which is slightly lower than the melting point of the polystyrene, 110 degrees Celsius, is used as the foam polystyrene. When overlapped on the panel and lightly pressed, the overlapped part of the grid-like wire mesh of polystyrene is softened, and air bubbles are lost to form a groove, and at the same time, the part of the one side of the grid wire mesh is formed in the groove. It is embedded and fixed.

[0011]

As described above, the panel for construction of the present invention is one in which one side of the lattice-shaped metal mesh is embedded and fixed in the foamed plastic panel by the heat of the heated three-dimensional metal mesh, as described above. The labor required for embedding and fixing the three-dimensional wire netting to the panel is reduced. Then, the plastic softened or melted by the heat of the heated three-dimensional wire mesh adheres to the three-dimensional wire mesh, so that the three-dimensional wire mesh and the foamed plastic panel are fixed to each other. Further, since a groove is formed by melting a part of the foamed plastic panel with a grid-shaped wire mesh in the heated three-dimensional wire mesh, a part of the foamed plastic panel is projected on the surface of the foamed plastic panel from which the wire mesh protrudes. It is possible to prevent When mortar or the like is sprayed onto the surface of the foamed plastic panel from which the three-dimensional wire mesh protrudes, the mortar or the like fits into the groove, so that the bond between the foamed plastic panel and the mortar layer can be strengthened.
