It is set up. At the other side end of the plate body, as shown in FIG. 3 (b), an engaging projection 11 extends outward over the entire length, and a bent piece 9 is provided at the tip inward. An inwardly facing piece 10 extends over the entire length.
The surface of the plate body 1 can be formed flat, or a groove can be formed in a pattern shape, and a nailing V-groove 12a is formed in the nailing piece 8 over the entire length. Or a hole 12b for nailing is machined. The filling of the resin foam 3 into the concave portion 2 on the back surface of the plate body 1 formed as described above can be performed by, for example, a double conveyor system as shown in FIGS. That is, this is an upper caterpillar
Using a double conveyor 17 formed of an upper conveyor 14 provided with 13 and a lower conveyor 16 provided with a lower caterpillar 15, the plate body 1 is set on the lower caterpillar 15 with the concave portion 2 facing upward, Then, a foamed resin liquid such as polyurethane or flame-retardant phenol resin is injected into the recess 2 from the injector 18 and the plate body is held between the upper and lower caterpillars 13 and 15 while being held between the side jigs 19 and 19 such as aluminum. 1 is introduced, the foamed resin liquid is foamed and cured in a state of being sealed between the upper and lower caterpillars 13 and 15, and the resin foam 3 can be filled in the recess 2. In addition to the double conveyor system, the resin foam 3 can be filled in the recess 2 of the plate body 1 by a method as shown in FIG. That is, the engagement recesses 3 on the conveyor 20
The plate bodies 1, 1... Are arranged with the concave portion 2 facing upward in a state where the platen bodies 1, 1. The resin foam 3 can be filled in the concave portion 2 of the plate main body 1 by spraying and foaming the rear surface. As described above, the building board A in which the resin foam 3 is filled in the concave portion 2 on the back face of the board body 1 as shown in FIG. A back sheet 22 made of aluminum foil or the like is attached. In this architectural plate A, since the plate main body 1 is an extruded product of aluminum, its cross-sectional shape can be faithfully formed to the shape of an extrusion die, compared with that formed by forming. The plate body 1 can be formed in a sharp shape with high dimensional accuracy. Further, since aluminum can be formed as a color anodized or baked and painted, it does not rust even when used in a humid bathroom or swimming pool. Since the heat insulating material of the resin foam 3 exists, the surface of the plate body 1 does not cause dew condensation to cause water droplets. In mounting the building plate A formed as described above on a wall surface, a ceiling surface, or the like, as shown in FIG. The fixing plate 26 is driven in to fix the architectural plate A, and the engaging protrusions 11 of the other architectural plate A are engaged with the engaging concave portions 7 of the architectural plate A to fix the architectural plate A. This can be done by making a connection. In connecting the architectural plate A in this manner, as shown in FIG. 7, the engaging projection 11 is engaged with the inner surface of the engaging recess 7 with the bent piece 9 in contact with the nailing piece 8. Therefore, the engagement projection 11 is engaged with the engagement recess 7 with a moment about the bent piece 9 as a fulcrum.
Can be engaged in a state of being in close contact with the inner surface of the. At one side end of the building plate A, a contact piece 24 is provided so as to protrude over the entire length, so that an joint groove 25 is formed between the building plates A. The construction piece A

The head 26a of the fixing tool 26 is accommodated in the second space 28. In the embodiment shown in FIG. 7, the building plate A is
Although the joint grooves 25 are formed between them, as shown in FIG. 8 (a), the joint pieces 24 are made to protrude flush with the surface of the plate body 1 so that the joint grooves 25 are not formed. The plate A can be connected flush. As shown in FIG. 8 (b), the building plate A can be connected flush without providing the contact piece 24.

[Object of the invention]

As described above, in the present invention, an aluminum extrusion-formed product is used to form a substantially flat U-shaped plate body with a back side opening, and a resin foam is filled in a concave portion with a back side opening of the plate body. As a result, the plate body formed of an extruded aluminum product can be formed in a sharper shape and with higher dimensional accuracy than that formed by forming. It can produce architectural plates well. Further, an engaging recess which opens outward is formed at one side end of the plate body, and a nailing piece is extended outward from the tip of the engaging recess. The engaging protruding piece extends outward and the inward piece provided with a bent piece at the tip extends inward, and the surface of the nailing piece of one plate body of the adjacent building plate is attached to the other plate. Since the bent pieces of the main body are brought into contact with each other and the engaging projections of the other main body are engaged with the inner surfaces of the engaging recesses of the one main body, the adjacent building boards are connected.
The engagement protruding piece of the other plate main body can be engaged with the inner surface of the engagement recess of the one plate main body in close contact with the moment with the bent piece as a fulcrum. ,
The connection can be made with a high connection strength, and the plate body is formed of an extruded aluminum product with high dimensional accuracy, so that the connection portion can have high waterproofness and connection strength. Further, an abutting piece protrudes outward from one side end of the plate body so that the abutting piece of one plate body of the adjacent building plate abuts on a side end of the other plate body. As a result, a space can be formed between the side edges of the plate bodies of adjacent building plates by the abutting pieces, and this space allows water to infiltrate from between the plate bodies of adjacent building plates by capillary action. This can prevent the waterproofing, and can further enhance the waterproofness.
