The specific embodiment
Core of the present invention is to provide a kind of H shaped steel, to improve stock utilization and to overcome local buckling's distortion.
In order to make those skilled in the art understand better the present invention program, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1-Fig. 7, the structural representation of H shaped steel the first specific embodiment that Fig. 1 provides for the embodiment of the present invention; The structural representation of H shaped steel the second specific embodiment that Fig. 2 provides for the embodiment of the present invention; The structural representation of the third specific embodiment of H shaped steel that Fig. 3 provides for the embodiment of the present invention; The structural representation of the 4th kind of specific embodiment of H shaped steel that Fig. 4 provides for the embodiment of the present invention; The structural representation of the 5th kind of specific embodiment of H shaped steel that Fig. 5 provides for the embodiment of the present invention; The structural representation of the 6th kind of specific embodiment of H shaped steel that Fig. 6 provides for the embodiment of the present invention; The structural representation of the 7th kind of specific embodiment of H shaped steel that Fig. 7 provides for the embodiment of the present invention.
The H shaped steel that the embodiment of the present invention provides, comprise top flange 2, bottom flange 3 and be arranged on top flange 2 and bottom flange 3 between wave webs 1.wherein wave webs 1 refers to its cross section and has bending, rather than plane, concrete can be the trapezoidal cross-section structure, sine curve or cosine curve section structure, retangular section structure, circular section structure or triangular section structure etc., wave webs 1 also can be called corrugated web, wherein, the width range of top flange 2 and bottom flange 3 can be 200～1500mm, the thickness range of top flange 2 and bottom flange 3 can be 6～40mm, the altitude range of wave webs 1 can be 400～3000mm, the thickness range of wave webs 1 can be 2～16mm, adopt wave webs 1 can reach the shearing resistance total cross-section effective, improved the shear resistant capacity in cross section, thereby can make thinner, from heavy and light, raw material have been saved, improved stock utilization, and broken through the restriction of traditional flat web H shape steel web ratio of height to thickness, overcome the problem of the easy local buckling of flat web distortion.
