Embodiment Construction

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] see Figure 1-3 , the embodiment of the present invention provides an H-shaped steel, which includes: a web 1, an upper flange 2 (or a first flange) and a lower flange 3 (or a second flange). Both ends of the web 1 are connected with the upper flange 2 and the lower flange 3 respectively. In order to improve the strength of the H-beam, the upper flange 2 and the lower flange 3 are arranged in parallel, and the web 1 is perpendicular to the upper flange respectively. flange 2 and the middle of the lower flange 3 are arranged. The cross-section (or cross-section) of the web 1 is preferably rectangular. When the H-shaped steel provided in the embodiment of the present invention is applied to the manufacture of a steel structure cladding...

Abstract

The invention discloses an H-section steel. The H-section steel comprises a web, a top flange and a bottom flange; the web is located between the top flange and the bottom flange, and connected with the top flange and the bottom flange, respectively; the surface of each of the top flange and the bottom flange comprises an inner side surface and an outer side surface opposite to the inner side surface; the inner side surfaces of the top flange and the bottom flange both are connected with the web; lugs are arranged on the outer surface of the top flange and / or the outer surface of the bottom flange. According to the H-section steel, the surface of a component using the H-section steel is skid-resistant, sound-proof, and capable of relieving impact load.

Description

technical field [0001] The invention relates to the technical field of hot-rolled section steel, in particular to an H-section steel. Background technique [0002] During the construction of subways, trestle bridges, three-dimensional parking garages, steep-slope lanes, housing passages and other facilities, the use of cladding panels can effectively reduce construction time and improve work efficiency when repairing roads, building access roads in disaster areas, and constructing temporary platforms. [0003] With the continuous development of the domestic steel structure field, the original cladding panels made of concrete and steel began to be gradually replaced by steel cladding panels. Restricted by the production technology and equipment of hot-rolled channel steel, its accuracy is difficult to meet the requirements of use, while cold-formed steel has high shape accuracy, but its section performance stability is poor. SUMMARY OF THE INVENTION [0004] In order to so...
