The secondary water-stopping material for joints is fixed, and the displacement can be easily prevented. In addition, since the secondary waterproofing material for joints is not directly attached to the steel frame using double-sided tape or the like, it is easy to remove and attach, and dust such as release paper does not occur. Furthermore, if the legs or protrusions are integrally molded so that they are located at the center of the seal part, the center of the secondary water-stopping material for joints will come to the center of the gap just by press-fitting into the gap between the steel frames, so labor is required for positioning. You don't have to spend. In addition, the mounting position of the leg portion or the protruding portion with respect to the seal portion is not limited to the central portion, and can be changed according to the positional relationship between the joint position and the gap between the steel frames. Also, since the locking parts are pressed into the gaps between the steel frames and the steel frames are connected and stabilized, the steel frames are placed horizontally on the ground and the secondary water-stopping material for joints is attached from there, and the outer wall For example, not only the work of mounting the panel to the steel frame by bolting it and then standing it vertically, but also installing the secondary water stop material for joints with the steel frame standing vertically, and further bolting the outer wall panel to the steel frame. It is possible to easily carry out the work of mounting by attaching.

In addition, since the secondary waterproofing material for joints is not directly attached to the steel frame using double-sided tape or the like, it is easy to remove and attach, and dust such as release paper does not occur. Furthermore, if the legs or protrusions are integrally molded so that they are located at the center of the seal part, the center of the secondary water-stopping material for joints will come to the center of the gap just by press-fitting into the gap between the steel frames, so labor is required for positioning. You don't have to spend. Also, since the locking parts are pressed into the gaps between the steel frames and the steel frames are connected and stabilized, the steel frames are placed horizontally on the ground and the secondary water-stopping material for joints is attached from there, and the outer wall For example, not only the work of mounting the panel to the steel frame by bolting it and then standing it vertically, but also mounting the secondary water stop material for joints with the steel frame standing vertically, and further bolting the outer wall panel to the steel frame. It is possible to easily carry out the work of mounting by attaching.

In addition, the stopper function of the legs or protrusions that are integrally molded with the seal portion allows positioning to be performed when the legs or protrusions come into contact with the steel frame even if the secondary water stop material for joints is displaced relative to the steel frame. Therefore, the positional displacement can be easily prevented.

る。Further, according to the invention of claim 3, since the seal portion is made of EPDM sponge rubber and the leg portion or the protrusion is made of EPDM solid rubber, any one of the seal portion and the leg portion or the protrusion is formed. Also, compared with those made of EPDM sponge rubber or EPDM solid rubber, the sealing function by the seal portion and the function for fixing by the leg portion or the protrusion portion are effectively exhibited. According to the invention as set forth in claim 4, the seal portion and the leg portion or the protrusion are provided with the EPD.
Since the member is made of M solid rubber and the member made of EPDM sponge rubber is integrally formed on the outer wall panel side surfaces of both ends of the seal portion, the sealability is partially improved. Further, according to the invention described in claim 5, since the seal portion is made of water-expandable rubber, the sealability is further improved. Claim 6
According to the invention described in (1), since the convex portion is integrally formed on the surface of the seal portion on the outer wall panel side, it is possible to further prevent the displacement of the joint secondary water stop material between the outer wall panels together with the leg portion or the protrusion.
