Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments of the present invention are based on the technical solutions of the present invention and are described in detail, but the present invention is not limited to the following embodiments.
As shown in fig. 1-4, the steel bent structure for the roof of the hydropower house outgoing line of the utility model is composed of a column 1, an upper beam 2, a lower beam 3, a fixing part 4 and a walking part 5.
Wherein, stand 1 is many welding combination box section's steel cylinder, every stand 1 all includes parallel arrangement's first steel sheet 1.1 and second steel sheet 1.2, be provided with third steel sheet 1.3 and fourth steel sheet 1.4 parallel to each other between the two, third steel sheet 1.3 and fourth steel sheet 1.4 are perpendicular mutually with first steel sheet 1.1 and second steel sheet 1.2, and the first end of third steel sheet 1.3 links to each other with the inboard welding of first steel sheet 1.1, the second end of third steel sheet 1.3 links to each other with the inboard welding of second steel sheet 1.2, the third end of fourth steel sheet 1.4 links to each other with the inboard welding of first steel sheet 1.1, the fourth end of fourth steel sheet 1.4 links to each other with the inboard welding of second steel sheet 1.2, in addition, first steel sheet 1.1, second steel sheet 1.2, the bottom of third steel sheet 1.3 and fourth steel sheet 1.4 is all welded on bottom plate 1.5. The bottom plate 1.5 of each upright post 1 is connected with the reinforced concrete bent frame column of the hydropower house through an anchor bolt 1.6, and reinforcing ribs 1.7 are arranged between the bottom plate 1.5 and the first steel plate 1.1, the second steel plate 1.2, the third steel plate 1.3 and the fourth steel plate 1.4.
