Fireproof protection and decoration integrated structure on steel member

Abstract

The invention discloses a fireproof protection and decoration integrated structure on a steel member. The fireproof protection and decoration integrated structure comprises the steel member, a steel structure interface mortar layer, a steel wire mesh and a wall spraying mortar layer, wherein the steel member is a bearing structure of a steel structure building; the steel structure interface mortarlayer is applied to the surface of a to-be-sprayed wall spraying mortar layer of the steel member; the steel wire mesh is laid on the surface of the steel structure interface mortar layer; the wall spraying mortar layer is sprayed to the surface of the steel wire mesh and wraps the steel member, the steel structure interface mortar layer and the steel wire mesh completely, and a fireproof protection and decoration integrated layer is formed. Compared with the traditional wrapping and decoration for the steel member through fireproof paint and a light-gauge steel joist system, the novel wall spraying mortar structure for the steel member has the advantages that the system is excellent in fireproof performance, good in overall performance and free of hollowing and cracking, the wall is light in mass, dense, fireproof, sound-insulating, heat-insulating, comfortable, simple and fast to construct, high in practicability and easy to popularize and use, and a construction environment is clean and tidy.

Description

technical field [0001] The invention relates to the technical field of prefabricated steel structure buildings, in particular to an integrated structure of fire protection and decoration on steel components. Background technique [0002] A steel structure building is a building made of building steel to form a load-bearing structure. Beams, columns, trusses and other components usually made of section steel and steel plate constitute the load-bearing structure. Together with the enclosure structures such as roofs, floors and walls, they form a whole-planted building. Construction section steel usually refers to hot-rolled angle steel, channel steel, I-beam, H-beam and steel pipe. The advantages of steel structure buildings include: 1) greatly saving construction time, and construction is not affected by seasons; 2) increasing the usable area of ​​residential space, reducing construction waste and environmental pollution; 3) building materials can be reused, driving the dev...

Problems solved by technology

[0003] Its disadvantages include: 1) heat resistance is not fire-resistant, and fire-resistant coatings need to be coated on the surface; 2) it is susceptible to corrosion, and anti-corrosion coatings need to be coated on the surface to reduce or avoid corrosion and increase the durability

3) It needs to be wrapped with a light steel keel system to meet the decoration requirements, with many processes and high cost
