Abstract

PURPOSE:To obviate the necessity of welding of a unit opening adapted to be formed between steel beams, in a job site, and enable the opening frame and an upper frame to be slidable so as to absorb deformation by external force through sliding of upper part of vertical frames. CONSTITUTION:The lower ends of vertical frames 51 of a unit opening frame 5 which has been manufactured beforehand in a firm, are set on the upper surface of a lower beam 3, and bolts are inserted into bolt holes in the upper surface of the lower beam 3 and in retainer plates 8. The lower end parts of the retainer plates 8 are fixed to a vertical surface 4A of a T-like shape steel bar 4 so as to allow the opening frame 5 to self-stand on the upper surface of the lower beam 3. Then, the vertical surface of the retainer member 7 is pressed against the vertical frames 51 and is fastened to the upper surface of an upper beam 1 while the upper end parts of the vertically frames 51 are fixed at the vertical surface of a retainer member 7. Further, the opening frames 5 are fitted between the upper and lower beams l, 3, and accordingly, the attachment structure of a unit opening frame 5 adapted to be fixed between the upper and lower beams 1, 3 is constituted. Thereby, a vibration insulating structure for restraining deformation of each of the members can be obtained.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a unit opening formed between steel beams.

[0002]

2. Description of the Related Art Openings for windows, daylighting, ventilation, etc. are formed in a building structure formed by using plate panels such as ALC. And these openings are generally
An angle frame is assembled into a # shape and welded to a steel beam or the like to provide an opening frame. In addition, the sash forming the window frame is also attached to the opening by on-site welding or the like. A plate panel such as ALC forming a wall surface is fixed to a steel frame body or the like by welding or the like on a mountain steel forming an opening frame through a hook metal fitting or the like.

[0003]

However, in the case of the conventional mounting structure for the opening frame, as described above, the opening frame is welded to the steel frame body or the like, so that the welding work at the construction site is not required. There is a problem that a lot of on-site work is complicated, and that the welding work is easily affected by the weather and the welding management is difficult. In addition, since the panel plate that forms the wall surface has a rigid structure that is integrated with the mountain steel that forms the opening frame through the hook hardware, etc., when external force acts on each member due to strong wind, earthquake, etc. However, there is a problem in that the amount of deformation varies depending on the difference in the elastic coefficient of each member, a gap is generated between the members, a crack is generated on the wall surface, and sometimes the member falls off.

Therefore, an object of the present invention is to eliminate the welding work at the site at all, and to make it possible to slide without connecting the opening frame and the upper frame, and to absorb the deformation caused by an external force by this slide. It is to provide a frame mounting structure.

Incidentally, Japanese Patent Application Laid-Open No. 1-284647 discloses that
It describes an open frame mounting structure that eliminates any on-site welding work.

[0006]

According to the present invention, there is provided a first metal object having a vertical surface attached along a lower surface of an upper beam, and a vertical surface attached to an upper surface of a lower beam so as to face the first metal object. And a unit opening frame having a pair of left and right vertical frames which are erected between the two metal objects, and the lower end of each vertical frame of the unit opening frame is pressed against the vertical surface of the second metal object. The fastening members fastened to the lower beam so as to be fixed in the state, and the upper ends of the vertical frames whose lower ends are fixed by these fastening members are pressed against the vertical surfaces of the first metal object, respectively. And a pressing member for sandwiching the pressing member, the pressing member being bolt-fastened to the upper beam so that the position of the unit beam can be adjusted. Is.

[0007]

According to the present invention, after mounting each vertical frame of the unit opening frame on the upper surface of the lower beam, a fastening member is attached to the lower beam, and the fastening member is fastened to the lower beam, whereby a vertical surface of the second metal object is obtained. The lower end of each of the vertical frames is pressed against the above to fix the unit opening frame to the upper surface of the lower beam in a self-supporting state, and then the upper end of each of the vertical frames is first moved by the pressing member attached to the upper beam. It is possible to form a mounting structure for the unit opening frame by pressing the metal object to a vertical surface and sandwiching and fixing each lower end portion between the pressing member and the vertical surface.
