Energy-saving fireproof steel structure for green building

Abstract

The invention discloses an energy-saving fireproof steel structure for a green building. The energy-saving fireproof steel structure comprises a base, wherein the top of the base is fixedly connected with a steel main body; a water tank is arranged inside the steel main body; a fixing mechanism is arranged at the outer side of the water tank and is positioned inside the steel main body; and an elastic jacking mechanism is arranged at the inner wall of the steel main body and is positioned under the fixing mechanism. Through the arrangement of a spring, after the certain temperature is reached, the heating can be performed to reduce the elasticity; at the moment, a rotating plate and a jacking plate are in a vertical state with the inner wall of the steel main body under the gravity effect; meanwhile, the jacking plate is abutted against the inner wall of the steel main body, so that the inner wall of the steel main body can be supported between the rotating plate and the jacking plate; the toughness of the steel main body is improved; after the fire hazard is completed, the temperature recovers to the normal state; the spring recovers the original position and jacks the jacking plate to upwards move; the jacking plate is not in contact with the inner wall of the steel main body; the inside of the steel main body can be effectively cooled; and the influence on the inside stability due to too high temperature caused by inside temperature gathering of the steel main body can be avoided.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to an energy-saving fireproof steel structure for a green building. 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. Welding, bolt or rivet connection, because of its light weight and easy construction, is widely used in large factories, stadiums, super high-rises and other fields. [0003] However, in the process of using the steel structure, due to the poor fire resistance of the steel structure, in the event of a fire, the steel structure is easily affected by high temperature and its rigidity is reduced, which affects the stability of the steel structure. Firefighting is prone to unnecessary losses. Contents of the invention [0004] The obje...
