Environment-friendly building energy-saving fireproof steel structure

Abstract

The invention provides an environment-friendly building energy-saving fireproof steel structure which comprises a steel column. The lower end of the outer part of the steel column is provided with a water storage mechanism, and the inner part of the water storage mechanism is provided with a water delivery mechanism. When a fire occurs, when people are not on site, under the action of high-temperature flame, a carbon wire is rapidly burnt off, at the moment, the upper part of a counterweight pressing block loses tension and rapidly slides to the upper end face of a base under the action of gravity, so that keys in a control switch are rapidly pressed downwards, and then a circulating water pump is started through the pressed control switch, therefore, a water source in the water storage mechanism is sprayed to the outer peripheral surface of a fireproof layer outside the steel column through a water spraying mechanism for fireproof cooling operation, the water spraying cooling operation can be quickly carried out on a steel structure support column without manually starting a water pump by people after a fire occurs, and the practicability of the steel structure support column is greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of steel structures, and more specifically, relates to a green building energy-saving fireproof steel structure. Background technique [0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large-scale factories, venues, super high-rise buildings and other fields. [0003] For example, application number: 201810448930. 1 The present invention discloses a fire-resistant steel structural column, which includes square steel. One side wall of the squa...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an energy-saving and fire-resistant steel structure for green buildings to solve the problem that although some of the existing steel structure pillars are equipped with water spraying mechanisms to perform fireproof and cooling treatment on the outer walls of the steel structure pillars, people need to manually start the water pump. The steel structure pillars can be sprayed with water only after operation, and it cannot be sprayed and cooled automatically when a fire occurs, which greatly reduces the practicability of the steel structure pillars, and the water source sprayed on the steel structure pillars will directly It flows to the ground, causing waste of water sources, which cannot be recycled, and due to the lack of anti-corrosion measures on the existing steel structure pillars, the water source will also cause corrosion after flowing on the steel structure pillars, affecting the steel structure pillars The problem of support strength
