Embodiment Construction

[0030] exist figure 1 In the process, the antimagnetic stainless steel bar 1 and the antimagnetic stainless steel bar 1 cannot be in contact with each other, and the plastic film 2 is cut into thin strips, and wound on several intersection points of the antimagnetic stainless steel bar 1 and another antimagnetic stainless steel bar 1, and then the insulating rope 3 Bind the two antimagnetic stainless steel bars 1 firmly.

[0031] exist figure 2 In the shown embodiment, the plastic film 2 is cut into thin strips and wound on the lapped beam and column longitudinal reinforcement 4 to ensure insulation from the closed stirrup 5 of the beam and column. Wrap the plastic film 2 on several intersections of the vertical steel bar 6 and the horizontal steel bar 7 of the shear wall respectively to ensure insulation from the tie bar 8 .

[0032] exist image 3 In another embodiment shown, the shear wall in the antimagnetic area, the vertical steel bar 9 of the column and the shear wa...

Abstract

The invention relates to a construction method for antimagnetic stainless steel bars in an antimagnetic area of a transformer room. The steel bars applied in the antimagnetic area adopt the material in the type of austenite OCr18Ni9Ti or 1Cr18Ni9Ti. Antimagnetic stainless steel main bars are formed by carrying out single-sided or double-sided overlap welding on stainless steel welding rods; the antimagnetic stainless steel bars (1) on a plurality of crossing points in the antimagnetic area are partitioned through plastic films (2), and are tied up through insulating ropes (3) to form closed loops. The construction method has the advantages in that the major technical problems that metal components in a magnetic source are heated due to the strong magnetic field eddy current around the transformer, the steel bars in the concrete structure deform due to heating, electrolytic loss is caused, and concrete cracks are solved; the strength, rigidity, bearing capacity, shock resistance and building durability of the concrete structure are enhanced; the requirement of equipment safety operation is ensured.

Description

technical field [0001] The invention relates to the construction technology of antimagnetic stainless steel bars in the antimagnetic areas of LF furnaces and RH furnace transformer rooms in steel mills, and in particular provides a construction method for antimagnetic stainless steel bars, which is suitable for the construction of stainless steel bars in the antimagnetic areas of transformer rooms in LF furnaces and RH furnaces in steel plants. Background technique [0002] Electric arc furnaces and ladle refining furnaces are important equipment in steel mills. The functions of LF furnaces are arc heating, increasing alloy yield, fine-tuning molten steel composition, uniform molten steel composition and temperature, improving steel cleanliness and changing the shape of inclusions. Desulfurization, as a buffer link between converter and continuous casting, to ensure the matching rate of converter continuous casting, and to realize multi-furnace continuous casting. The transf...
