According to the architectural structural material of the invention according to the third aspect, the connecting projections of the plate-shaped first member and the plate-shaped second member made of an extruded aluminum member constituting a wall or the like are provided. The connection part appears outside and is not visible, and therefore has an extremely good appearance and excellent design.

When a fire occurs in a building using the structural material of the present invention, a butt-welding of the first and second plate-shaped aluminum extruded members constituting the structural material is performed. The connection consisting of typically about 660
According to the present invention, since the outer surface of the connecting portion is covered with the covering material for concealing the connecting portion, the connecting portion hardly reaches the melting temperature, and therefore the structural material for building is used. Has no decrease in strength even at high temperatures, is excellent in fire resistance and fire resistance, and has high safety.

Further, in the structural material for building according to the third aspect,
The plate-shaped first member and the plate-shaped second member are both made of an extruded aluminum member, and the pair of connecting portion concealing covering members are made of the same extruded aluminum member as the first member and the second member, or ceramic. Or, since it is made of fiber reinforced thermosetting resin (FRP), etc., the structural material for building can be manufactured in various shapes because of its light weight and easiness of processing, and the appearance is very high. It is beautiful and has excellent design.

Further, since the structural material for building is mainly composed of the first and second members made of extruded aluminum, the first and second members are connected to each other.
There is an effect that a large-sized building structural material can be easily manufactured.

According to a fourth aspect of the present invention, there is provided the first member and the second member, wherein the covering material for concealing the connecting portion is made of an extruded material and has an outwardly convex portion at a central portion. One edge of the covering material for concealing the connecting portion covered on the outer surface of the connecting portion of the first member is inserted into the insertion concave portion of the same connecting edge of the first member, and the convex portion for locking the covering material side edge portion. In the state where the other side edges of both coating materials are inserted into the insertion concave portions of the same side connection edges of the second member and are engaged with the coating material side edge locking projections. The outer convex portions at the center of both coating materials are located between the short coating material side edge locking convex portions facing each other, and the outer convex portions of the outer convex portions of both coating materials are locked. Since the outer surface of the convex portion is substantially flush with the outer surface, the appearance of the connection portion between the first member and the second member is further improved,
It has the effect of being excellent in design.
