An energy-saving steel structure unit

Abstract

The invention discloses an energy-saving steel structure unit, comprising a column member, an internal member and an embedded part. The column member includes a bottom plate, a hollow steel column vertically arranged on the top of the bottom plate, a cover body screwed on the top of the hollow steel column, and the same The shaft is arranged in the guide tube inside the hollow steel column, the bottom end of the guide tube is welded with the top of the bottom plate, the outer side wall of the bottom end of the guide tube is evenly provided with air inlet holes along its circumferential direction, and the height of the guide tube is lower than that of the hollow steel column, and the side wall of the hollow steel column above the guide tube is evenly provided with ventilation holes along its circumferential direction; the internal components include a sealing plug slidably arranged inside the hollow steel column above the guide tube, and a sealing rod slidably arranged inside the guide tube . By filling the hollow steel column with a low-cost fine sand layer and a sandstone layer, the invention makes the hollow steel column form a "solid" column, which effectively improves the overall strength of the column, and can also appropriately reduce the thickness of the hollow steel column. The amount of steel used to reduce costs.

Description

technical field [0001] The invention relates to the technical field of energy-saving steel, in particular to an energy-saving steel structure unit. Background technique [0002] At present, steel structure supports are required in many fields, such as load-bearing structures of buildings, internal load-bearing or divided structures of large transportation vehicles, aircraft racks, and so on. The existing steel structure supports are mainly used for beams and columns on buildings, and most of them use hollow cylindrical structures, but as the temperature continues to increase, their load-bearing performance will be greatly reduced, the beams and columns will be bent and deformed, and the overall beams and columns are easy to move. position, causing the instability of the entire building. If you want to solve this problem, you can solve it by thickening the thickness of the steel plate, and adding a cooling device. SUMMARY OF THE INVENTION [0003] The purpose of the prese...

Problems solved by technology

Existing steel structure supports are mainly used for beams and columns on buildings, most of which adopt hollow cylindrical structure, but as the temperature continues to increase, its load-bearing performance will be greatly reduced, beams and columns will be bent and deformed, and the whole beam and column will easily move. bit, causing instability in the entire building

If you want to solve this problem, you can solve it by thickening the thickness of the steel plate and adding a cooling device. The first type has a large amount of consumables, high cost, and troublesome production
