DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for fixing a base panel to a steel frame constructed at a construction site.

[0002]

2. Description of the Related Art A steel-frame building is constructed by constructing a steel frame at a construction site, fixing a base panel to the steel frame, and then fixing an outer wall to the outdoor side of the base panel. In this method, it is important to fix the base panel to the steel frame in a short time. The reason is that a steel frame building to which the base panel is fixed does not allow rain and wind to enter, so that subsequent construction can be performed extremely efficiently.

The sectional views of FIGS. 1 and 2 show a vertical sectional view of a steel-frame building constructed by a conventional method. The steel frame building of FIG. 1 is constructed by the following steps. A flat bar 2 is welded and fixed at the exact position of the steel horizontal structure 1, that is, the beam, at the construction site or at the factory. A steel frame or a wooden tab 3 is fixed to the constructed steel flat bar 2. A panel 4 such as a structural plywood or a control panel is fixed to the surface of the trunk 3. The heat insulating material 5 is fixed to the inner surface of the panel 4 such as a structural plywood.

[0004] The steel frame building shown in FIG. 2 is constructed by the following steps. The constructed horizontal structure 1 of steel frame,
At a precise position of the beam, a through hole for fixing the toe 3 is opened. A toe 3 is fixed to an opposing surface of a beam, which is a horizontal structural member 1 arranged vertically in parallel with bolts 6.
Panels 4 of structural plywood, control panel, etc. on the surface of the toe 3
Is fixed. The heat insulating material 5 is fixed to the inner surface of the panel 4 such as a structural plywood.

After the base panel is fixed to the steel frame in the above steps, a waterproof sheet 7 is stretched on the outdoor side of the base panel, and an outer wall 8 is fixed on the waterproof sheet 7.

[0006]

The construction method of a steel frame building shown in FIGS. 1 and 2 is to fix a body bar by welding a flat bar 2 to a beam which is a horizontal structural member, or to provide a through hole in the beam. Since the panel 4 is opened and the panel 4 is fixed, a high level of technology is required, and it is difficult to fix the body edge and the panel at an accurate position. This is because if the positions of the body edge and the through hole are shifted, the panel cannot be fixed at an accurate position. In order to fix the torso and panel in the correct position, the craftsman carefully
If the flat bar or the body edge is fixed, or if a through-hole is opened, it takes time, and the base panel cannot be fixed efficiently. In particular, this method requires a considerable amount of time to fix the flat bar and the body edge and to open the through hole, and if the work is carefully performed, the time becomes extremely long, so that the construction cannot be performed efficiently.

For this reason, the construction method of a steel frame building shown in FIGS. 1 and 2 has the disadvantage that the quality varies because it depends on the skill of a field craftsman and that the construction cannot be performed efficiently and in a short period of time. Furthermore, in this construction method, after fixing a structural plywood or the like, a heat insulating material such as glass wool is fixed on the inner surface thereof. Insulation slips,
Deformation such as crushing Variations in construction accuracy such as wrinkles in gaps, or forgetting to insert Reduced insulation performance due to moisture and dew condensation Dirt on site due to chips from insulation material The more properly the insulation work, the more man-made and the number of days

[0008] The present invention has been developed for the purpose of solving such disadvantages. An important object of the present invention is to provide a method of constructing a base panel in a steel frame building, which can fix the base panel at an accurate position simply, easily, and efficiently.
