Embodiment 1

[0069] A steel fireproof structure provided in this embodiment includes: a steel structure and an anti-corrosion and fireproof protective shell 100; Figure 1-2 As shown, the steel structure is a column Z10.

[0070] The anti-corrosion and fire-proof protective shell 100 is a prefabricated panel body 110 made of ultra-high performance concrete, high-performance concrete or high-performance mortar, and the prefabricated panel body 110 is provided with strength and rigidity for enhancing the anti-corrosion and fireproof protective shell 100, and preventing corrosion. The cracked reinforced skeleton 120 of the fire protection shell 100; the anti-corrosion and fire protection shell 100 is coated on the steel structure, and is used for anti-corrosion and fire prevention of the steel structure.

[0071] Wherein, the thickness of the anti-corrosion and fire-proof protective shell 100 is preferably 10mm-50mm.

[0072] The column body 200 may be an H-shaped steel column, a box-shaped ...

Embodiment 2

[0092] The steel structure fireproof structure provided in this embodiment differs from Embodiment 1 in that:

[0093] like Figure 3-5 As shown, the steel structure is steel beam L10. The anti-corrosion and fire-proof protective shell 100 is a prefabricated plate body 110 made of mortar emulsion and nano-material additives. The pre-fabricated plate body 110 is provided with a device for enhancing the strength and rigidity of the anti-corrosion and fire-resistant protective shell 100 and preventing the anti-corrosion and fire-resistant protective shell 100 from cracking. Strengthen the frame 120; the anti-corrosion and fire-proof protective shell 100 is wrapped around the steel beam L10, and is used for the anti-corrosion and fire prevention of the steel beam L10.

[0094] Wherein, the thickness of the anti-corrosion and fire-proof protective shell 100 is preferably 20mm-30mm.

[0095] The anti-corrosion and fire protection shell 100 is a U-shaped piece with a U-shaped cross-s...

Embodiment 3

[0103] The steel structure fireproof structure provided in this embodiment differs from Embodiment 1 in that:

[0104] like Image 6 As shown, the steel structure is a shear wall S4. The anti-corrosion and fireproof protective shell 100 is provided with connection holes, and the shear wall S4 is provided with connection pins S4a (for example, welded with bolts) that fit in the connection holes. The shear wall S4 is covered with two layers of anti-corrosion and fire-proof protective shells 100; in the thickness direction, the innermost anti-corrosion and fire-resistant protective shells are arranged at intervals from the shear wall, and the intervals are filled with insulation materials 210. During construction, the innermost The anti-corrosion and fire-proof protective shell forms a mold, and the insulation material is filled to form an insulation layer outside the shear wall; an interlayer is arranged between two adjacent anti-corrosion and fire-proof protective shells, and ...

Abstract

The invention provides a steel structure fireproof structure and a building comprising the same. The steel structure fireproof structure comprises a steel structure part and an anti-corrosion and fireproof protective shell; the anti-corrosion and fireproof protective shell is a prefabricated part made of mortar emulsion and a nanometer material additive, and a reinforcing framework used for enhancing the strength and rigidity of the anti-corrosion and fireproof protective shell and preventing the anti-corrosion and fireproof protective shell from cracking is arranged in the prefabricated part;and the anti-corrosion and fireproof protective shell wraps the steel structural part and is used for corrosion prevention and fire prevention of the steel structural part. The steel structure fireproof structure has the advantages of being high in standardization degree, high in construction efficiency, easy and convenient in connection, good in anti-corrosion and fireproof performance, high indurability, wide in application range, good in economical efficiency and the like, and has good application prospects in steel structure engineering.

Description

technical field [0001] The invention relates to the technical field of steel structure engineering, in particular to a steel structure fireproof structure and its building. Background technique [0002] At present, steel structures have been widely used due to their advantages such as fast construction speed, large constructable span, changeable shapes, and low overall cost. However, the corrosion resistance and fire resistance of steel structures are poor. Anti-corrosion and fire protection directly determine the normal service life of steel structures. To some extent, durability issues are the constraints that restrict the large-scale promotion of steel structures and the service life of existing steel structures. a key factor. Some durability problems of steel structures are even directly related to their safety. For example, the corrosion of steel structures will lead to the deterioration of steel properties and weaken the effective bearing area of ​​steel components, t...
