Fireproof energy-saving steel structure

Abstract

The invention discloses a fire-resistant energy-saving steel structure which comprises a supporting column, a connecting column, a supporting frame, a supporting structure and a connecting assembly, the connecting column is of an I-shaped rod-shaped structure, a fastening cavity is formed in the connecting column in the axis direction of the connecting column in an extending mode, and positioning grooves are formed in the I-shaped outer side edge of the supporting column at equal intervals. A supporting structure is arranged at the positioning groove, and connecting assemblies are installed at the two ends of the supporting column. The connecting assembly comprises a connecting block, a protruding column and a protruding plate, the connecting block is of an I-shaped block structure, the protruding column is fixed to one side edge of the connecting block, the protruding column is of a rectangular block structure, fastening holes are formed in the two ends of the protruding plate and the two ends of the connecting column, and the protruding plate and the connecting column are fixed through fastening bolts. The fireproof and energy-saving steel structure is reasonable in design, capable of improving the whole and edge supporting effect of the middle section of the steel structure, convenient to install and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of steel structures, and in particular relates to a fire-resistant and energy-saving steel structure. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and antirust processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. [0003] Most of the existing energy-saving steel structures are hollow inside. When encountering extreme problems such as fire, the internal support effect of the steel structure is insu...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing energy-saving steel structures are hollow inside. When encountering extreme problems such as fire, the internal support effect of the steel structure is insufficient, which may easily cause problems such as disconnection of the steel knot from the middle section.
