A screw hole 34e is formed in which a screw for engaging is screwed.

  When the vertical bone 17 is fixed to the lower frame 13, first, the lower frame fixing member 32 is inserted and accommodated in the recess 13 c of the lower frame 13 from the end in the direction of finding. In this state, the upper surface of the seat portion 32a of the lower frame fixing member 32 is close to the lower surfaces of the outdoor-side extension portion 13g and the indoor-side extension portion 13h, and the raised portion 32d on the upper surface of the seat portion 32a enters the slit 13b. .

And the lower frame fixing member 32 is arrange | positioned in the position where the right end 32f and the edge part 13k of the left side of the wide part 13j align. At this time, the through hole 13l provided in the outdoor side wall portion 13e and the screw hole 32g provided in the outdoor leg portion 32b overlap each other in the prospective direction. Then, a screw 25 as a fixing tool penetrating the outdoor side wall portion 13e is passed through the through hole 13l and screwed into the screw hole 32g to fix the lower frame fixing member 32 to the lower frame 13.
After fixing the lower frame fixing member 32 to the lower frame 13, the sponge 36 is inserted into the recess 13 c from the widened portion 13 j of the lower frame 13, and the sponge 36 is disposed adjacent to the lower frame fixing member 32.

  Next, the longitudinal bone fixing member 34 is disposed so that the base portion 34a of the longitudinal bone fixing member 34 is bridged over the outdoor side extending portion 13g and the indoor side extending portion 13h above the lower frame fixing member 32. Then, the screw passing through the through hole 34d of the base portion 34a is screwed into the screw hole 32h provided in the raised portion 32d of the lower frame fixing member 32 to fix the longitudinal bone fixing member 34 to the lower frame fixing member 32. At this time, a slight gap is provided between the lower surface of the base portion 34a placed on the outdoor side extension portion 13g and the indoor side extension portion 13h and the top surface of the raised portion 32d. By tightening, a force acts so that the space | interval of the lower surface of the base 34a and the top face of the protruding part 32d becomes narrow. For this reason, the outdoor side extending portion 13g and the indoor side extending portion 13h arranged between the longitudinal bone fixing member 34 and the lower frame fixing member 32 are connected to the longitudinal bone fixing member 34 and the lower frame fixing member 32. The lower frame 13, the lower frame fixing member 32, and the longitudinal bone fixing member 34 are firmly fixed. In particular, the lower frame 13 has a shape in which the concave portion 13c is provided with a slit 13b and is opened upward in a single state. When a large force is applied, the outdoor side wall portion 13e and the indoor side wall portion 13f may be deformed. The outdoor-side extending portion 13g and the indoor-side extending portion 13h are sandwiched between the longitudinal bone fixing member 34 and the lower frame fixing member 32 so that the open portion is connected and has the same rigidity as the hollow member. Become. Further, when the longitudinal bone fixing member 34 is fixed to the lower frame fixing member 32, even if an excessive force acts on the indoor side extension portion 13h and the outdoor side extension portion 13g, the deformation may occur. Since the top surface 32e of the raised portion 32d in the seat portion 32a contacts the lower surface of the longitudinal bone fixing member 34, the deformation amount of the indoor side extending portion 13h and the outdoor side extending portion 13g can be suppressed.

  Thereafter, a water-stop sheet 37 is placed on the sponge 36 and the portion of the lower frame fixing member 32 that does not overlap the vertical bone fixing member 34. Here, the water stop sheet 37 is formed in a shape that substantially overlaps the horizontal section of the vertical bone 17.

  The vertical bone 17 is placed on the arranged water-stop sheet 37. At this time, the vertical bone 17 is placed on the waterstop sheet 37 from above so that the fixing plate portion 34 b and the extending portion 34 c of the vertical bone fixing member 34 that are already fixed enter the hollow portion 17 a of the vertical bone 17. To do. Further, the surface on the left side in the finding direction of the fixing plate portion 34b of the longitudinal bone fixing member 34 (the surface on the side opposite to the protruding direction of the extending portion 34c) is brought into contact with the inner surface of the left side portion 17b of the longitudinal bone 17. Then, a screw passing through the through hole 17c of the left side portion 17b from the left side in the finding direction is screwed into a screw hole 34e provided in the fixing plate portion 34b of the vertical bone fixing member 34, and the vertical bone 17 is fixed to the vertical bone fixing member 34. As a result, the vertical bone 17 is firmly fixed to the lower frame 13.
