In recent years, H profile steel is a kind of economical section steel, is widely used in industry, building, bridge, oil drilling platform
In terms of, it is predicted that about 2,500,000 tons of China's H profile steel demand in 2005,2,010 5,000,000 tons of annual requirements, but China's H types at present
Steel annual production capacity is 1,200,000 tons, and market demand is very huge.
At present, at present, in use, in order to improve the rigidity and bearing capacity of structure, especially for large span
Structural upright, it is often necessary to combine and use, cause the increase of cost, service life reduction, rate of metal it is high and
The problem of material can not be utilized effectively.
The content of the invention
The purpose of this utility model is, to solve to have existing H profile steel drawbacks described above, and then provides a kind of hot rolling
" convex " font structure steel, hot rolling " convex " the font structure steel is structure as a whole, above and below hot rolling " convex " the font structure steel is divided into
Structure, i.e. top are boss, and bottom is base；Two outsides of the junction of the boss and the base are handled using circular arc,
And form the first fillet and the second fillet；The inwall on boss top and the inwall of two inner sides of boss form respectively the 3rd circle
Angle and the 4th fillet；The inwall of two inner sides of the base forms the 5th fillet and the 6th with two inner sides of the junction respectively
Fillet；The inwall of the bottom of the base and the inwall of its two inner side form respectively the 7th fillet and the 8th fillet.
Hot rolling " convex " the font structure steel is symmetrical, and the top of the boss and the bottom of the base are mutual
It is parallel.
The cross section of the boss is trapezoidal or rectangle.
The cross section of the base is trapezoidal or rectangle.
The lateral length of the base is 20-200mm, and the distance of top to the bottom of the base of the boss is
10-50mm。
The angle of first fillet and second fillet is 90-120 °, and the radius of the two is 1-6mm.
The angle of 3rd fillet and the 4th fillet is 90-95 °, and the radius of the two is 1-6mm.
The angle of 5th fillet and the 6th fillet is 90-120 °, and the radius of the two is 1-6mm.
The angle of 7th fillet and the 8th fillet is 85-90 °, and the radius of the two is 1-6mm.
The utility model has the advantage of：
1) Cross section Design of hot rolling " convex " font structure steel of the present utility model rationally, improves structure integral rigidity and held
Loading capability；
2) production cost is reduced, the service life of structure is improved；
3) hot rolling " convex " font structure steel integrative-structure design of the present utility model, passes through hot rolling one-shot forming, production effect
Rate and rate of metal are significantly improved.
