Fireproof heat-preservation safety type steel structure

Abstract

The invention discloses a fireproof heat-preservation safety type steel structure, and belongs to the technical field of steel structures. A fireproof plate is arranged on an outer end wall of a main steel plate, and a fireproof layer matched with a plurality of steel bars is arranged on the face, connected with the main steel plate, of the fireproof plate, so that good heat-insulation and fireproof effects are achieved; the plurality of reinforcing bars are matched, and a mechanical strength of the steel structure is effectively improved; meanwhile, fireproof wrapping bag layers and water absorption foam layers are embedded in the fireproof plate in a staggered mode, and hot melting water bag bodies are connected to the outer end faces of the water absorption foam layers in an embedded mode. When the steel structure encounters a fire disaster, the hot melting water bag bodies are hot-melted in a high-temperature environment to release a water solution, the water solution is guided into the water absorption foam layers through high-water-absorption fibers so that the temperature of the water absorption foam layers can be reduced, and flame retardant property of the fireproof plate is further enhanced. It should be noted that the plurality of hot melting water bag bodies are arranged on an outer end wall of the fireproof plate, and the waterproof and heat-insulation fireproof layer is arranged at the joint of the fireproof plate and the main steel plate, so that water is effectively prevented from permeating into the main steel plate.

Description

technical field [0001] The invention relates to the technical field of steel structures, and more specifically, relates to a fireproof and thermal insulation safe 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 steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. Compared with ordinary reinforced concrete structures, steel structures have the advantages of homogeneity, high strength, fast construction speed, good earthquake resistance and high recovery rate. The strength and elastic modulus of steel are many times higher than that of masonry and concrete. Therefore, under load Under the same conditions, the quality of steel components is lighter.

AI Technical Summary

Problems solved by technology

[0003] The steel structure in the prior art has poor thermal insulation performance and poor fire resistance, and is easily deformed in a high temperature environment, especially in a fire environment

In terms of fire protection, the traditional method is to store water inside the steel structure. However, if the water is directly placed in contact with the steel structure, it will easily cause the steel structure to rust, which will reduce the mechanical strength of the steel structure, making it difficult to achieve Long-lasting fire and flame retardant properties
