Embodiment Construction

[0013] Refer to the attached figure 1 to attach image 3 The ribbed channel steel for a train roof of the present invention will be described in detail below.

[0014] The structure of the ribbed channel steel for train roof of the present invention includes a channel steel body 1 on which a reinforcing rib 2 is arranged vertically along the channel steel body 1 . The strength of the channel steel body 1 is increased, no deformation or fracture occurs, the shock absorption effect is good, and the use will not be affected.

[0015] The waist height h of the channel steel body 1 1 for Waist thick a 1 for Leg length L 2 for Leg end thickness a 2 for The inclination angle λ of the inner leg is 8°.

[0016] Described reinforcing rib 2 comprises straight section 5 and the arc section 4 that is arranged on the both sides of straight section 5, and the length of described straight section 5 is 2.1mm, and the radius of arc section 4 is 6mm, and arc section 4 and The wais...

Abstract

The invention discloses ribbed channel steel for a train top plate and belongs to a hot rolled sectional material product. The ribbed channel steel structurally comprises a channel steel body, wherein reinforcing ribs are arranged on the channel steel body, and the reinforcing ribs are in vertical arrangement along the channel steel body. Compared with the prior art, the ribbed channel steel for the train top plate has the characteristics that the intensity of the channel steel body is enhanced, the deformation or the fracture cannot occur, the shock absorption effect is good, the use cannot be influenced, and the like. Therefore, good popularization and application values are realized.

Description

technical field [0001] The invention relates to a hot-rolled profile product, in particular to a ribbed channel steel for a train roof. Background technique [0002] Now when the channel steel used for the train roof is in use, the shock absorption effect of the train wheels is poor, and the channel steel is not strong enough, and often deforms or breaks, which affects the use. Currently, there is no good solution. Contents of the invention [0003] The technical task of the present invention is to provide a kind of ribbed channel steel for train roof in view of the deficiencies in the above-mentioned prior art. The shock effect is good and will not affect the characteristics of use. [0004] The technical scheme adopted by the present invention to solve the technical problem is: it includes a channel steel body, the channel steel body is provided with reinforcing ribs, and the reinforcing ribs are vertically arranged along the channel steel body. [0005] The waist hei...
