If it does so, the water stop property between the insertion main body 21 and the fitting 6 can be improved.
Thereby, even if the joinery 6 is provided close to the entrance corner 1 and the gap S1 between the second outer wall 3 and the joinery 6 is narrow, the processing related to fire resistance and water stoppage in the gap S1 is easy. And it can be done reliably. And by providing the entrance corner cover member 20 in the gap S1 in this way, the fireproof / water stop line from the first outer wall 2 to the second outer wall 3 with the opening 5 can be connected without interruption. As a result, even when the joinery 6 is provided close to the corner 1, excellent fire resistance and water stoppage can be ensured in the gap S <b> 1 between the joinery 6 and the second outer wall 3.

  In addition, since the incombustible material 24 is sandwiched and held between the base portion 22 fixed to the second outer wall 3 and the surface side portion 23 provided so as to overlap the base portion 12, the nonflammable material 24 is It can support reliably in the state inserted in gap S1.

Further, the non-combustible material 24 is interposed between the main body plate portion 22b protruding from the fixing plate portion 22a of the base portion 22 toward the fitting 6 side and the main body plate portion 23b protruding from the fixing plate portion 23a of the surface side portion 23 toward the fitting fitting 6 side. Therefore, the incombustible material 24 can be disposed along the protruding direction of the main body plate portion 22b of the base portion 22 and the main body plate portion 23b of the surface side portion 23. That is, the incombustible material 24 can be provided from the second outer wall 3 to the fitting 6.
Thereby, since a fireproof line between the second outer wall 3 and the joinery 6 can be secured, the fireproof line from the first outer wall 2 having the opening 5 to the second outer wall 3 can be connected without interruption. it can.

  Further, since the notch portions 23d2 and 23e2 are formed at the corners on the corner 1 side of the upper surface plate portion 23d and the lower surface plate portion 23e, the notch portion 23d2 is formed when the insertion body 21 is inserted into the gap S1. , 23e2 can be formed with a gap. Thereby, since ventilation and drainage can be performed using the notches 23d2 and 23e2, the dry state inside the insertion body 21 can be maintained.

  Moreover, since the depth dimension along the insertion direction to the clearance gap S1 of the upper surface board part 23d and the lower surface board part 23e is set substantially equal to the protrusion dimension from the surface of the 1st outer wall 2 in the fitting 6, it is an upper surface board part. The position of the front end in the protruding direction of 23d and the lower surface plate portion 23e is aligned with the position of the front end in the protruding direction of the fitting 6. As a result, the surface of the main body plate portion 23b provided between the upper surface plate portion 23d and the lower surface plate portion 23e and the front end surface in the protruding direction of the joinery 6 are flush with each other. In this case, the appearance of the corner 1 can be improved.
