Channel steel casting

Abstract

The invention discloses a channel steel casting comprising a channel steel wall. A supporting triangle plate is arranged at the position, close to the middle position, above the channel steel wall, atwo-end supporting triangular prism is arranged at the end, close to the supporting triangle plate, on the channel steel wall, the middle portion of the inner portion of the two-end supporting triangular prism is provided with a two-end supporting triangular prism internal thread strip-shaped hole, a strip-shaped bolt is arranged at the position, close to the inside of the two-end supporting triangular prism internal thread strip-shaped hole, of the two-end supporting triangular prism, a nut is arranged at the end, far away from the two-end supporting triangular prism, above the strip-shaped bolt, a containing groove is arranged inside the channel steel wall, a column-shaped gear is arranged above the containing groove, a limit block is arranged at the end, far away from the column-shapedgear, of the containing groove, and an internal thread strip-shaped hole is formed in the end, far away from the limit block, inside the channel steel wall; and by designing a side groove, the bolt, the internal thread strip-shaped hole and the column-shaped gear which are installed on the channel steel wall, splicing of channel steel is facilitated, and the problem that the channel steel cannot be conveniently spliced during use is solved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a channel steel casting. Background technique [0002] Channel steel is a long strip of steel with a groove-shaped cross-section. The cross-sectional shape is a channel-shaped steel. Channel steel is a carbon structural steel for construction and machinery. It is a section steel with complex sections, and its cross-sectional shape is groove-shaped. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billet for producing channel steel is carbon structural steel or low alloy steel billet with carbon content not exceeding 0.25%. The finished channel steel is delivered in the state of hot forming, normalizing or hot rolling. Channel steel is divided into ordinary cha...
