Background
The steel structure is mainly made of steel and is one of the main building structure types. The steel has the characteristics of high strength, light dead weight, good integral rigidity and strong deformability, so the steel is particularly suitable for building large-span, ultrahigh and overweight buildings; the material has good homogeneity and isotropy, belongs to an ideal elastomer and most conforms to the basic assumption of general engineering mechanics; the material has good plasticity and toughness, can deform greatly and can bear dynamic load well; the construction period is short; the method has high industrialization degree and can be used for professional production with high mechanization degree. The steel structure needs to research high-strength steel, so that the yield point strength of the steel structure is greatly improved; in addition, new types of section steel, such as H-section steel (also called wide-flange section steel), T-section steel, profiled steel sheet, etc., are rolled to meet the needs of large-span structures and super high-rise buildings.
The adhering and reinforcing steel structure is adhered to the surface of the damaged part of the steel structure by using an adhesive, so that part of load is transmitted to the steel structure through the adhesive layer, and the stress of the damaged part of the structure is reduced. The bonding and reinforcing technology has obvious advantages: (1) the specific strength and specific rigidity are high, and the self weight of the original structure and the size of the original component are basically not increased after the reinforcement; (2) the composite material has good fatigue resistance and corrosion resistance; (3) flexible composite materials are particularly advantageous for any closed structure and reinforced structural surfaces of complex shape. The sealing performance is good, and the hidden danger of leakage and even corrosion is reduced; (4) the method is simple, convenient and easy to implement, low in cost and high in efficiency, can be constructed in a narrow space, and is particularly suitable for field repair; (5) the construction process has no open fire, and is suitable for various special environments.
However, the existing building adhesives have less characteristics and insufficient capability, and for example, in a patent document with the publication number of CN104449536A, a building adhesive for a steel structure is disclosed; the feed is prepared from the following raw materials in parts by weight: 2-3 parts of nano zinc oxide, 53-58 parts of polytetrahydrofuran ether glycol, 18-22 parts of isophorone diisocyanate, 2-4 parts of epichlorohydrin, 4-6 parts of dimethylethanolamine, 5-6 parts of nano tungsten trioxide, 9-12 parts of 6101 epoxy resin, 9-12 parts of carboxyl-terminated liquid polybutadiene rubber, 9-12 parts of nano silicon carbide, 1.5-2 parts of dodecylbenzene sulfonic acid, 6-9 parts of zinc isooctanoate and 5-6 parts of boron trifluoride monoethylamine. The building adhesive for the steel structure has strong adhesive force, good mechanical property and normal temperature curing, particularly has high steel-steel bonding shear strength and steel-concrete bonding shear strength, good toughness and impact resistance, and the steel-steel bonding tensile strength reaches 61.8 MPa; but the binder has insufficient high temperature resistance, rust resistance, corrosion resistance and service life, and is difficult to meet the requirements of building development.
