The surface joint material 4b as a primary watertight material is formed of EPDM (ethylene / propylene rubber), and the foamable refractory material 8 is installed inside the same as the vertical joint material 2a. This foam-type refractory material 8 is a standard product in which ammonium polyphosphate and black carbon are mixed in a urethane resin,
A material that foams and forms a carbonized layer at the temperature of 00 ° C and blocks the flame. In the event of a fire, the vertical joint material 2a becomes a refractory material and blocks the passage of the flame toward the inside or outside of the building via the joint. The joint consisting of the vertical joints 2 and the horizontal joints 4 is configured to change to a fireproof structure in the event of a fire.

The outer surface of the surface joint material 4b is provided with an outer cover 4d formed of a material having high weather resistance such as chlorosulfonated polyethylene. The sponge layer 4c as the secondary watertight material is formed of EPDM sponge. Various types of the sponge layer 4c are conceivable. Examples of the sponge layer 4c include EPTO (Nitto Denko) as EPDM (open cell type), Nipperon JS Soft (trade name from Nihon Denko as foamed polyurethane), and Nippon Epoxy as urethane foam. And the like. As shown in FIG. 2 (a), the sponge layer 4c is projected more laterally than the surface joint material 4b at the end of the horizontal joint material 4a in the longitudinal direction. In the contacted state, as shown in FIG. 2 (b), the adjacent sponge layers 4c are elastically deformed and are strongly pressed against each other, so that the sponge layers 4c are connected to each other without forming a gap. Here, the connecting portions of the adjacent horizontal joint materials 4a are arranged at positions avoiding the intersections of joints, as indicated by reference numeral a in FIG.

The material 2a is compressed, and the upper and lower portions of the vertical joint material 2a slightly project from the upper and lower ends of the outer wall panel 1,1 or the outer wall panel 3,3. This slightly protruding vertical joint material 2a is the horizontal joint material 4a.
Since the vertical joint material 2a is harder than the horizontal joint material 4a, it is pressed against the horizontal joint material 4a without bulging to the surface side. Since the end portions of the respective vertical joint materials 2a are pressed against the continuous horizontal joint material 4a at the intersection, a gap is unlikely to be generated between the horizontal joint material 4a and the vertical joint material 2a. .

However, when the outer wall panels 1 and 3 are attached and installed, the vertical joint material 2a is installed so that the outer wall panels 1 and 3 provided in advance at one end are sequentially attached and installed. When the outer wall panel 1 is completely attached, the horizontal joint material 4a is installed on the upper part between the adjacent outer wall panels 1 on the lower floors, and the outer wall panel 3 on the upper floor is sequentially installed on the horizontal joint material 4a. is there.

At the intersection of joints, the upper end of the vertical joint material 2a between the outer wall panels 1 on the lower floors adjacent to each other is the horizontal joint material 4 at the upper end.
The lower end of the vertical joint material 2a between the adjacent outer wall panels 3 on the upper floor is pressed against the upper surface of the horizontal joint material 4a, and the horizontal joint material 4a is continuous at the intersection. Since the horizontal joints 4 are arranged, no gap is generated in the horizontal joints 4, and the end portions of the vertical joint members 2a are pressed against the continuous horizontal joint members 4a at the intersection. As a result, the joint portion of the joint can be finished so that no gap is generated between the vertical joint 2 and the horizontal joint 2.
