Problems solved by technology
[0004] In related technologies, fire-resistant coatings are applied on the surface of steel structures according to the fire-resistant limit. However, due to the heavy weight of the fire-resistant coatings, poor adhesion, and easy local or even overall falling off, the parts of the fire-resistant coatings that fall off will be damaged due to the increase in temperature when a fire occurs. Deformation, can not achieve the expected effect

The invention discloses an intelligent waterproof system of a water-cooled steel structure and a fire-resisting method thereof. The system comprises a collecting basin, a steel structure unit frame, awater outlet pipeline, a water return pipeline, a water pump and a regulating valve, wherein the collecting basin is provided with a water outlet and a water return port, and cooling water is arranged in the collecting basin; the steel structure unit frame is provided with a water inlet and a drain outlet; one end of the water outlet pipeline communicates to the water outlet while the other end of the water outlet pipeline communicates to the water inlet; one end of the water return pipeline communicates to the drain outlet wheel the other end of the water return pipeline communicates to thewater return port; the water pump is arranged on the water outlet pipeline, so that water in the collecting basin flows into the water inlet from the water outlet; and the regulating valve is arrangedon the water outlet pipeline and is located between the water pump and the steel structure unit frame. According to the intelligent waterproof system of the water-cooled steel structure, the steel structure unit frame can be cooled quickly through circular flowing, so that the fire resistance and the structural stability of the steel structure unit frame can be improved.
Description
technical field [0001] The invention relates to the technical field of steel structures, in particular to a water-cooled steel structure intelligent fire prevention system and a fire resistance method thereof. Background technique [0002] Steel structure has the advantages of high strength, light weight, good toughness, good plasticity, high reliability, good sealing, convenient construction and high degree of mechanization of manufacturing and installation. It is widely used in industrial plants, long-span structures and high-rise structures. It is one of the more common architectural forms now. [0003] As we all know, steel has the disadvantage of heat resistance and fire resistance, which has always been a difficult problem in engineering. When a fire occurs, if the ambient temperature is ≤150°C, the performance of the steel remains good at this time, but when the temperature rises to 450°C-600°C, the strength and elastic modulus of the steel will drop sharply, and whe...
