  However, in the conventional structure, although the fire resistance required for the air passage is sufficiently satisfied by the thickness of the tubular member 103 and the thickness of the grooved steel constituting the tubular support frame 102, the chopped grooves There was a problem that work efficiency was low because it took time to assemble the mold steel. Furthermore, when the position of the cylindrical member 103 is changed in accordance with each house, there is a disadvantage that the cylindrical support frame 102 interferes with the brace 101b. Further, the technique disclosed in Patent Document 1 does not use the cylinder support frame 102 and thus does not cause the above-described problem, but has a drawback that the structure of the cylinder member is complicated.

  In view of the above circumstances, an object of the present invention is to provide a structure for a through portion of an outer wall panel that has a simple structure of a cylindrical member, a simple support structure, and easy assembly.

  In order to solve the above-described problems, the structure for the through-wall portion of the outer wall panel according to the present invention has a tube main body portion and a flange portion at a location where the through-wall portion of the outer wall panel is formed, and the tube main body portion serves as an air passage A cylindrical member made of a thick steel material satisfying the fire resistance performance is provided by sandwiching the flange portion between an outer wall plate and an outer wall base plate of the outer wall panel.

  If it is said structure, since the said cylinder main-body part consists of a thick steel material which satisfies the fireproof performance as an air passage, the structure of a nonflammable material etc. are unnecessary and its structure is simple. In addition, since the cylindrical member is provided with the collar portion sandwiched between the outer wall plate and the outer wall base plate of the outer wall panel, the support structure is simple and easy to assemble. Further, since a cylindrical support frame made of channel steel is not used, problems such as interference between this and the brace do not occur.

  A screw for installation of equipment may be screwed onto the flange. According to this, since the screw is screwed into the flange portion, the screw is less likely to come out than the case where the screw is screwed to the outer wall plate or the outer wall base plate. Equipment such as a hood can be securely attached to the outside of the outer wall panel.

  A division part is formed in the outer wall base plate, and the division part may have an opening through which the cylinder main body part of the cylinder member is inserted. According to this, it is only necessary to prepare a divided portion having an opening at a position suitable for individual housing specifications and to attach the same to the outer wall panel except for the divided portion. This improves the efficiency of assembling the outer wall panel compared to forming an opening at a position that meets individual housing specifications for one large outer wall base plate.

  Further, the base plate on the inner side surface of the outer wall panel is also formed with a split portion having an opening at a position corresponding to the position of the cylindrical main body portion of the cylindrical member. And the divided portion of the outer wall base plate may be a unit. According to this, the assembly efficiency of the outer wall panel is further improved. In addition, when a unit is used, assembly at the factory becomes easy, and it is possible to assemble the groundwork without groundwork at the construction site, thereby reducing the work load at the site.

  According to the present invention, the cylindrical member has a simple structure, and the support structure is simple and easy to assemble.
