The cross section of the member constituting the steel frame 2 may be any shape such as a groove shape, a groove shape with a lip, and a square shape. The outer periphery of the steel frame 2 is preferably formed to be slightly smaller than that of the concrete plate 1 for convenience when attaching the outer wall panel to the building.

At the four corners of the steel frame 2, mounting back nuts 22 are provided, and mounting of the outer wall panel to the building body is performed by tightening bolts to the mounting back nut 22. Fastener plates 21 are welded to the corners of the steel frame 2, and mounting back nuts 22 are provided at the four corners of the steel frame 2 via the fastener plates 21. The mounting back nut 22 has a through hole 26 formed in the fastener plate 21, the washer 23, and the back plate 4 and a nut hole communicating with each other. The washer 23 is provided so as to eliminate a step generated between the fastener plate 21 and the back plate 4. One mounting back nut 22 is provided at each of the upper two corners of the steel frame 2, and two mounting back nuts 22 are provided at each of the lower two corners, to secure the mounting strength of the outer wall panel.

Reference numeral 24 in FIG. 6 denotes a construction back nut welded to the steel frame 2. The construction back nut 24 is used for screwing an omega bolt and lifting the outer wall panel with a crane. Therefore, the construction back nut 24 is provided at two or more locations.

A back plate 4 is adhered to the back surface of the steel frame 2, and the back surface of the steel frame 2 is closed by the back plate 4. As the back plate 4, a flexible boat which is flexible and has good workability, fireproofness, soundproofness, and moistureproofness, a calcium silicate plate, a gypsum board, an iron plate, and the like are preferable. The back plate 4 is attached to the back surface of the steel frame 2 using screws, an adhesive, or the like.

The anchor 3 may be a bar or a strip-shaped steel plate. When a strip-shaped steel plate is used, the resistance to the concrete plate 1 increases.

A plate-like heat insulating material 5 is loaded inside the steel frame 2. As the plate-like heat insulating material 5, an inorganic material is preferable from the viewpoint of fire resistance, and for example, rock wool, glass wool, or the like is used.

In the manufacture of the outer wall panel, the other end portions 32 of the plurality of anchors 3 are provided on the steel frame 2 at appropriate intervals.
Is welded. Of course, when the anchor 3 is welded to the steel frame 2, the fastener plate 21 having the washer 23 and the mounting plate back nut 22 is also welded to the steel frame 2. The other end 3 of the anchor 3
The welding of 2 may be on the upper or lower side of the steel frame 2 or on the inner surface.

The steel frame 2 to which the anchor 3 and the like are welded is suspended from the side wall of a mold (not shown).
That is, the one end 31 of the anchor 3 can be buried in the concrete plate 1 (so as to be located substantially at the center of the plate thickness). Also, steel frame 2 and concrete plate 1
And a ventilation space S can be formed between them. The ventilation space S has an interval of about 5 mm to 20 mm. Thus, a cement slurry mixed with glass fibers or the like is poured into the mold. Horizontal leveling is performed so that the cement slurry has a predetermined thickness using a vibrating vibrator. Demold after steam curing. Thereafter, the back plate 4 is attached to the back surface of the steel frame 2 to form an outer wall panel.

Before attaching the back plate 4 in this manner,
The above-mentioned plate-shaped heat insulating material 5 is preferably loaded inside the steel frame 2.

[0022]

According to the outer wall panel of the present invention, the steel frame to which the anchor is welded and the concrete plate are firmly cured by curing and curing the other end of the anchor in a state where the anchor is embedded in the slurry of the concrete plate material. They can be linked. In addition, a ventilation space is formed between the plate-shaped heat insulating material in the steel frame and the concrete plate via this anchor ,
The ventilation between the plate-shaped heat insulating material and the concrete plate can be secured to prevent the occurrence of dew condensation inside the outer wall panel. Further, since this ventilation space can be used as a path for evaporating excess moisture of the concrete plate, it is possible to prevent corrosion of the anchor and the steel frame and improve durability.

Also, the steel frame is welded to the other side.
