DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall panel mounted on a wall of a building.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional outer wall panel a has a grooved steel c with a lip embedded in a concrete plate b in the longitudinal direction.

[0003] The outer wall panel "a" is mounted by fitting a bolt member mounted on a wall of a building to the above-mentioned grooved steel plates "c" and "c" for locking.

[0004]

However, since the conventional outer wall panel a is mounted in contact with the wall of the building, it cannot release the heat inside the building and release moisture. There was a problem that it could not be done.

[0005] For this reason, there is a problem that the interior of the building is easily filled with heat and the humidity is easily increased.

An object of the present invention is to solve the above-mentioned conventional problems.

That is, it is an object of the present invention to provide an outer wall panel having excellent heat insulating properties.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a frame having a substantially Z-shaped cross section is mounted near the left and right sides on the back surface of a concrete plate, with a substantially half-side portion embedded and attached. A frame with a U-shaped cross section is mounted near the upper and lower sides with approximately half the side buried,
The buried lower flange of the frame having a substantially Z-shaped cross section is directed inward of the concrete plate, and the upper flange protruding is directed to the outer side of the concrete plate. On the back side of these Z-shaped and U-shaped cross-section frames, there is provided a U-shaped cross-section reinforcement frame having an open portion directed inward, and a heat insulating material is provided inside the reinforcement frame. It has been provided.

[0009]

According to the heat insulating outer panel, a gap is formed in a frame portion between a concrete plate and a heat insulating material provided in a reinforcing frame, and an air layer formed by the gap and a reinforcing frame are formed. It has a two-layer heat insulating structure with the heat insulating material provided in the part.

FIG. 5 is an exploded perspective view of the outer wall panel main body 1 and the reinforcing frame 5, and FIG. 5 is a perspective view showing an attached state of the outer wall panel main body 1 and the reinforcing frame 5 in the outer wall panel 1a of FIG.

In the outer wall panel 1a according to the present invention, frames 3, 3 having a substantially Z-shaped cross section are mounted near the left and right sides on the back surface of the concrete plate 2 with the substantially half sides buried therein, and the upper and lower sides are positioned closer to the upper and lower sides. Frames 4 and 4 having a U-shaped cross section are mounted so as to bury the substantially half sides thereof, and open portions of the Z-shaped frames 3 and 3 and the frames 4 and 4 having a U-shaped cross section are directed inward. A reinforcing frame 5 having a U-shaped cross section is provided, and a heat insulating material 8 is provided inside the reinforcing frame 5.

The embedded lower flange 31 of the frame 3 having a substantially Z-shaped cross section is directed inward of the concrete plate 2, and the protruded upper flange 32 is directed outward of the concrete plate 2. The letter-shaped frame 4 has an open portion 41
You are pointed outward.

The fixed state of the frame 3 having a substantially Z-shaped cross section and the frame 4 having a substantially U-shaped cross section is as shown in FIG.

That is, the frame 3 having a substantially Z-shaped cross section is welded along the back surface of both ends of the frame 4 having a U-shaped cross section in a state where the end faces thereof are in contact with each other.

FIGS. 3, 4 and 5 show a state in which a reinforcing frame 5 is attached to the outer wall panel body 1 to form an outer wall panel 1a.

The reinforcing frame 5 is composed of four long and short frame members 51, 51, 5 each having a U-shaped cross section with an open portion directed inward.
Long frame 5 composed of 2, 52 and located on the left and right sides
The end faces of the short frames 52, 52 are attached to the inner surfaces of both ends of the first and first ends 51 and 52 and welded.

A plurality of bolts 6 with nuts are welded to the upper flange 32 of the frame 3 having a substantially Z-shaped cross section in the outer wall panel body 1, and these bolts 6 project from the outer surface of the frame 3 having a substantially Z-shaped cross section. ing.

On the other hand, the long frame 51,
51 is provided with a plurality of bolt insertion holes 51a.

The projecting portions of the bolts 6 with nuts welded to the upper flange 32 of the frame 3 having a substantially Z-shaped cross section in the outer wall panel body 1 are inserted into bolt insertion holes provided in the long frames 51, 51 of the reinforcing frame 5. Inserted,
The reinforcing frame 5 is attached to the outer wall panel body 1 by screwing the nuts 7 to these bolts 6.

FIG. 3 shows a state in which a heat insulating material 8 is mounted in the reinforcing frame 5.

In the outer wall panel 1a of the present invention, a substantially half side of a frame 3 having a substantially Z-shaped cross section and a substantially half side of a frame 4 having a substantially U-shaped cross section project outward from the concrete plate 2, and these Z-shaped sections are formed. Frames 3 and 3 and the frames 4 and 4 having a U-shaped cross section, reinforcing frames 5 to which a heat insulating material 8 is attached are provided.
Is provided, the concrete plate 2 and the heat insulating material 8
Is formed between them.

As a result, the outer wall panel la can obtain a double heat insulating effect by the air layer in the gap 19 and the heat insulating material 8.

[0024]

As described above, according to the present invention, the air layer in the gap formed in the frame portion between the concrete plate and the heat insulating material provided in the reinforcing frame and the reinforcing frame portion are provided. Since it has a two-layer heat insulating structure with a heat insulating material, an excellent heat insulating effect can be obtained.
