Energy-saving steel structure unit

Abstract

The invention discloses an energy-saving steel structure unit. The energy-saving steel structure unit comprises a stand column component, an internal component and an embedded part, wherein the stand column component comprises a bottom plate, a hollow steel column perpendicularly arranged at the top of the bottom plate, a cover body connected to the top of the hollow steel column in a threaded mode and a guide pipe coaxially arranged in the hollow steel column, wherein the bottom end of the guide pipe is welded to the top of the bottom plate; air inlets are uniformly formed in the outer side wall of the bottom end of the guide pipe in the circumferential direction; the guide pipe is lower than the hollow steel column; air holes are uniformly formed in the side wall of the hollow steel column above the guide pipe in the circumferential direction; and the internal component comprises a sealing plug arranged in the hollow steel column above the guide pipe in a sliding mode and a sealing rod arranged in the guide pipe in a sliding mode. According to the invention, the hollow steel column is filled with low-price fine sand layer and gravel layer, so that the hollow steel column forms a solid stand column, the overall strength of the stand column is effectively improved, the thickness of the hollow steel column can be properly reduced, the steel consumption is reduced, and the cost is reduced.

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 partition structures of large transport vehicles, aircraft racks, and so on. 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 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. The first type has a large amount of consumables, high cost, and troublesome productio...
