  Hereinafter, a foam panel according to the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view of a foam panel according to the present invention according to the present invention. The foam panel 100 is a rectangular plate-like foamed polystyrene member 1 in which a reinforcing member 2 and a cross member 3 are incorporated. The reinforcing member 2 and the cross member 3 are indicated by dotted lines because they are inside the expanded polystyrene member 1. Although the dimension of the foam panel 100 is not restricted to this, a longitudinal direction is about 5 m and a transversal direction is about 2 m. Concave portions 4 and convex portions 5 are respectively provided on both front and rear end surfaces in the short direction. The concave portion 4 and the convex portion 5 are provided so as to extend in the longitudinal direction, and the concave portion 4 and the convex portion 5 are shaped to engage with each other. For example, the foam panel 100 can be extended in the short direction by engaging the convex portion 5 of another foam panel with the concave portion 4 of the foam panel 100. That is, the concave portion 4 and the convex portion 5 are coupling portions 12 for extending the foam panel 100 in the short direction. The cross member 3 is a belt-like flat plate material, and in this embodiment, the cross member 3 is attached to the reinforcing member 2 at intervals of 1 m in the longitudinal direction.

  FIG. 2 is a right side view of FIG. On the right side, the end surfaces of the internal reinforcing member 2 and the cross member 3 can be seen. Concave portions 4 and convex portions 5 are formed at both ends in the short direction. The concave portion 4 and the convex portion 5 serve as a coupling portion 12 that can connect the foam panel 100 and extend in the lateral direction. The expanded polystyrene member 1 has a height exceeding the reinforcing member 2 and the cross member 3 in the vertical direction. In this embodiment, the height of the reinforcing member 2 is about 100 mm, the thickness of the cross member 3 is 2 to 3 mm, and the thickness of the expanded polystyrene member 1 is about twice the height of the reinforcing member 2 and is about 200 mm. is there.

  FIG. 3 is a front view of FIG. A recess 4 is visible on the front. On the back side of the both ends in the longitudinal direction of the expanded polystyrene member 1, installation grooves 6 extending in the short direction are formed. The foam panel 100 is installed by engaging the installation grooves 6 at both ends in the longitudinal direction with installation projections provided on the upper part of the inner wall or the outer wall.

FIG. 4 is a perspective view of a framework composed of the reinforcing member 2 and the cross member 3. In this embodiment, the reinforcing member 2 and the cross member 3 are metal members. The cross member 3 is attached by welding or screws so as to be orthogonal to the reinforcing member 2. This frame is put in a mold, and the frame is installed so as to float from the bottom of the mold. Beads as a raw material for the expanded polystyrene member 1 are put into a mold, and expanded with high-temperature steam. Foam panel 100 is formed by such integral molding. In FIG. 4, the expanded polystyrene member 1 is indicated by a one-dot chain line. For example, the expanded polystyrene member 1 can have a weight per cubic meter of 14 kg to 30 kg by adjusting an expansion coefficient. Compressive strength ^has a ^{40kN / m 2 ~120kN / m 2} , it can withstand large loads. Flexural strength have ^{40kN / m 2 ~120kN / m 2} , resistant to bending. Thus, the expanded polystyrene member 1 is lightweight, excellent in heat insulation, and easy to process.

  FIG. 5 is an explanatory view showing a joined state of the joining portion 12 of the foam panel 100 of FIG. 1, and (A) shows joining by unevenness. That is, it is due to the engagement between the concave portion 4 and the convex portion 5. (B) shows the coupling by the step 9. (C) shows the connection by bolt connection. In the connection by the bolt, the end of the expanded polystyrene member 1 is processed so that the reinforcing member 2 and the cross member 3 come out on the side surface.

  FIG. 6 is a perspective view of the reinforcing member 2 of FIG. The reinforcing member 2 includes a web 2a serving as a base extending in the longitudinal direction, an upper flange 2b projecting from the upper end of the web 2a at a right angle toward one side in the short direction, and an upper flange 2b at a right angle from the lower end of the web 2a. And a lower flange 2c protruding in the opposite direction. As shown in FIG. 4, the reinforcing members 2 are arranged at intervals in the short direction so that the web 2a is vertical. A plurality of holes may be formed in the web 2a of the reinforcing member 2 to reduce the weight. Light weight can also be achieved by using light materials such as aluminum.

As a member having such a shape, a Z-shaped steel, which is one of lightweight section steels, can be used. The Z-section steel is referred to in this way because the cross section is close to the Z letter, but the Z-section steel web 2a is provided vertically and is not inclined. As for the shape of the Z-shaped steel, it is desirable that the web 2a is vertical, and there are no whiskers at the tips of the upper flange 2b and the lower flange 2c. This is because when there is a wraparound inside, when the raw material of the expanded polystyrene member 1 is foamed, a cavity is easily formed in this portion. Z-shaped steel can be expected to be 16 kN / cm ² for both compression and bending. Since it is 160 M / m ² in terms of conversion, it is a large value exceeding about 1000 times even when compared with the strength 120 kN / m ² of the expanded polystyrene member 1. In this embodiment, a Z-shaped steel having a height of the web 2a of 100 mm, a length of the upper flange 2b and the lower flange 2c of 50 mm, and a thickness of 2.3 mm was used as the reinforcing member 2.

  FIG. 7 shows an example in which the foam panel 100 according to the present invention is used under a floor on the floor. The foam panel 100 was used as a floor under the house floor. As shown in the drawing circle, both ends of the foam panel 100 in the longitudinal direction are stretched over the bulging portions 11 at the top of the two walls 10. At that time, the installation grooves 6 at both ends of the foam panel 100 are engaged with the installation protrusions 7 of the bulging portion 11. For this reason, there is no deviation in the assembly, and the assembly can be performed very easily. The wall 10 also has a reinforcing member inside, and the outside is a foamed polystyrene member. The space between the installation groove 6 and the installation projection 7 may be fixed with an adhesive. Further, bolts or the like may be passed inside the reinforcing member 2 and the cross member 3 and connected to the wall reinforcing member by a connecting member.

  The foam panel according to the present invention incorporates a Z-shaped reinforcing member integrally in the foamed polystyrene member, so that it has strength and is suitable for the floor under the floor.
