Problems solved by technology

The disadvantage of this kind of passive anti-corrosion is that, on the one hand, the amount of concrete and the self-weight of the tower body need to be increased due to the need to increase the thickness of the reinforced concrete protective layer; high

Embodiment 1

[0046] Such as figure 1 As shown, the resistance-reducing corrosion outer enclosure for reinforced concrete beams / columns 1 with a square cross-section described in this embodiment includes an inner shell 2 with open upper and lower ends and an outer shell 3 with open upper and lower ends. The outer shell 3 is made of hard polyvinyl chloride, and its outer surface is a streamlined hyperbolic cylinder, the front of the hyperbolic cylinder is round and the rear is pointed, and the surface is smooth. The fluid is mainly laminar on the surface of the hyperbolic cylinder, and there is no or There is very little turbulence. The inner housing 2 is coaxially arranged in the outer housing 3 and is connected with the inner housing 2 through an A-shaped tenon-and-mortise structure. The inner housing 2 is an arc plate made of hard polyvinyl chloride. The cross-section of the arc plate is a full circle circumscribed to the cross-section of the reinforced concrete beam / column 1, and the ou...

Abstract

The invention provides a resistance reduction anti-corrosion outer wrapping body for a reinforced concrete beam or column. The resistance reduction anti-corrosion outer wrapping body comprises an inner shell body with the open upper end and the lower end and an outer shell body with the open upper end and the lower end, the outer surface of the outer shell body is a streamlined hyperbolic cylinder surface, the outer shell body is coaxially provided with the inner shell body and can rotate around a shaft relative to the inner shell body, and the inner shell body is used for wrapping the reinforced concrete beam or column. After using the outer wrapping body in a cooling tower, while the reinforced concrete beam or column has a good anti-corrosion effect, ventilation resistance inside the tower is effectively reduced, the height of the cooling tower and operating power consumption are reduced, and thus the construction, operation and maintenance cost of the cooling tower can be significantly reduced.

Description

technical field [0001] The invention relates to an anti-resistance corrosion outer covering for reinforced concrete beams / columns, in particular to an anti-resistance corrosion outer covering for reinforced concrete beams / columns in cooling towers. Background technique [0002] Cooling tower is an important place to dissipate industrial waste heat into the atmosphere, and is an indispensable core structure in the field of industrial circulating cooling. Except for some small mechanical cooling towers that are assembled with glass fiber reinforced plastics and metal components, large, medium and super large cooling towers (including mechanical cooling towers and natural draft cooling towers) are mostly made of reinforced concrete. However, due to the severe humid heat and salt crystallization environment in the cooling tower (especially the seawater cooling tower and the exhaust cooling tower), the reinforced concrete outer surface of the cooling tower suffers from corrosion ...
