As shown in FIG. 8, the lower girder 34 and the upper girder 36 are connected by placing the lower flange 3602 of the upper girder 36 on the upper flange 3402 of the lower girder 34. It is performed by being detachably fastened with a high-strength bolt B.

A plurality of the small beams 38 are mounted and fixed on the plurality of upper large beams 36 so as to extend in the direction of the short side 14B of the virtual rectangle 14. More specifically, an H-beam is used as the small beam 38, and the length of the small beam 38 is twice as long as the short side 14 </ b> B of the rectangle 14.
8 is a so-called double beam in which an intermediate portion and both ends are connected on each upper large beam 36. As shown in FIG. 9, the upper flange 36 and the upper flange 36 are connected to each other.
The lower flange 3802 of the small beam 38 is placed on the small beam 02, and the two flanges 3602, 3802 are detachably fastened with the high-strength bolt B, so that a gap is provided between the ends of the adjacent small beams 36. Secured. Further, in order to prevent buckling of the lower girder 36, the angle member 40 having a simple structure is provided with the lower flange 3602 of the upper girder 36 and the lower flange 38 of the small girder 38.
It is passed between 02. The connection between the middle portion of the small beam 38 and the upper beam 36 is also performed by the upper flange 3602 of the upper beam 36.
The lower flange 3802 of the small beam 38 is placed on the lower beam, and both flanges 3602 and 3802 are detachably fastened with high-strength bolts B. Then, as shown in FIG. 3, a plurality of body edges 42 extending in the horizontal direction are connected to each steel column 24 at intervals in the vertical direction.
An outer wall 44 is attached to 2 and a roof 46 is attached to the beam 38.

According to this embodiment, a number of virtual rectangles 14 having the same shape are arranged with their long sides 14A and short sides 14B aligned with each other. In addition, the design of the factory including the positions and the numbers of the steel columns 24 and the columns 32 can be easily performed. In addition, foundation beam 1
8 is made to protrude above the ground surface GL to constitute a part of the interstitial concrete 16, so that the earth excavation depth can be reduced to reduce the amount of earth work, Since it becomes possible to cast concrete on both of the soil concrete 16 at the same time, it is possible to reduce man-hours and to make waste concrete unnecessary, which is advantageous in reducing costs.

Further, since the adjacent steel columns 24 are connected to each other by using the two braces 26 to which the gusset plates 28 are welded at both ends, the structure of the steel columns 24 is not complicated. It can be easily reinforced and is advantageous in reducing costs. Further, the steel columns 24 located at the outer ends of the upper girder 36 bear horizontal stress, and the lower girder 34
Since only the vertical force is borne by the column 32 located between the two ends of the building, it is possible to use a steel frame having a very small cross section as the column 32, and thus it is advantageous in increasing the internal space of the building. Become. Also, the support 32
Is a support column that does not bear horizontal stress, so that the column 32 can be freely moved in the horizontal direction, which is extremely advantageous in arranging equipment in a factory.

602, the top plate 2402 and the flange 36
02 is fastened with high-strength bolts B, so that a bracket is extended from the column as in the prior art, and the brackets, the upper and lower flanges of the upper girders and the webs are joined together, and the high-strength bolts are attached. This is extremely advantageous in reducing the amount of steel frames used and simplifying the construction as compared with the case of friction welding. When arranging the upper girders 36, the upper girders 36 and the lower girders 34 are connected to each other by the lower girders 3.
4, the lower flange 3602 of the upper beam 36 is placed on the upper flange 3402, and both flanges 3402 and 3602 are mounted.
Is performed by fastening with high-strength bolts B, so that the gusset plate and the attachment plate can be omitted as in the related art, and the construction can be simplified. Further, since the upper girder 36 is a connecting beam, the cross section thereof can be reduced, and the upper girder 36 can also be used as a member for imparting a roof gradient, which is advantageous in reducing the amount of steel frames used.

When arranging the small beams 38 on the plurality of upper beams 36, the small beams 38 are connected to the upper beams 36 by connecting the small beams 38 to the upper flanges 3602 of the upper beams 36.
The lower flange 3802 is placed on both flanges 360
Since 2,3802 is fastened with high-strength bolts B, the gusset plate and the attachment plate can be omitted as in the related art, and the construction can be simplified. Further, in this embodiment, since the small beam 38 is a double beam, the cross section of the small beam 38 can be reduced, which is advantageous in reducing the amount of steel frame used.

In this embodiment, the case where the present invention is applied to a one-story factory is described. However, the present invention can be applied to a skeleton of a building such as a warehouse having other plane dimensions larger than the height. Of course, it also applies to buildings with two or more floors.
