<p>Provided is a structure for reinforcing a web opening that makes it possible to increase the size of an opening through which piping passes without changing the height of the web of a steel frame. A structure for reinforcing the vicinity of a center opening (30), for piping, formed in a steel frame (1), which is provided with a plurality of steel frame parts (2) and a linking part (4) for linking adjacent steel frame parts (2) and disposed so as to extend horizontally. Each of the steel frame parts (2) has a web (10) disposed along the perpendicular direction and a pair of flanges (12, 14) disposed at the upper end part and the lower end part of the web (10) and linked to the web (10). The linking part (4) has: a rectangular steel pipe (20); and bolts (22) for joining the rectangular steel pipe (20) and the end parts of the flanges (12, 14), in a state in which the end parts of adjacent steel frame parts (2) are inserted in both end parts of the rectangular steel pipe (20) and the center opening (30) is formed between adjacent webs (10). The piping (100) passes through a side opening (32), the center opening (30), and a side opening (38).</p> |
