ものである。To explain with reference to the drawings, a waterproofing agent is applied to the surface of a concrete base 2 on which the L-shaped steel 1 is buried to form a waterproof layer 3, and a glue-like anticorrosion primer 4 is applied to the entire surface of the L-shaped steel 1. Next, a filling-proofing material 6 is applied to the entire corner 5 formed by the L-beam 1 and the waterproof layer 3, and the filling-proofing material 6 is covered, and the L-beam 1 and the waterproof layer are coated. The anti-corrosion tape 15 having the width of the layer 3 is wrapped to form the hem covering tape layer 16, and then the L-shaped steel 1 is wrapped around the edge 14 of the hem covering tape layer 16.
This relates to a method for preventing corrosion of an L-shaped steel building, which is characterized in that a coating layer 7 is formed by covering the entire surface of the structure with an anticorrosive tape 15.

りも多くして粘土状としたものである。The anticorrosion tape 15 has different widths depending on the location to which it is attached, and is attached while being pulled strongly. A tape cloth 10 is formed by sewing several sewing threads 9 made of strong synthetic fibers such as nylon, and contains petrolatum as a main component, and inert silica for viscosity adjustment is mixed in the petrolatum. A clay-like adhesive 11 formed by mixing and stirring a small amount of tannin and a rust inhibitor is permeated to form a permeable layer 12, and an adhesive layer 13 is provided on both ends of the permeable layer 120 and on the front and back surfaces. According to experiments, it is suitable for use if the tape cloth 10 is about 8φ, petroleum is about 60%, inert silica is about 30%, tannin and rust inhibitor are mixed in a small volume ratio. , paste-like anti-corrosion primer contains more petrolatum,
The amount of inert silica used as a hardening agent is reduced to make it thinner in order to make it easier to apply, and the filled anticorrosion 6 contains more inert silica as a hardening agent than the anticorrosion primer 4. It is clay-like.

錆の進行を抑制する。In addition, by impregnating the cloth tape 10 with a clay-like adhesive 11 to form a permeation layer 12 and providing adhesive layers 13 on both ends of the permeation layer 120 and on the front and back surfaces, the adhesive layer 13 is sufficiently adhered to the cloth tape 10. In addition, since the adhesive layer 13 has petrolatum as its main component, it does not evaporate or harden semi-permanently and always maintains viscosity to form an anti-corrosion layer semi-permanently, thereby eliminating the harmful effects of surface corrosion. In addition, because it contains a rust inhibitor, it changes red rust to black rust.
Suppresses the progression of rust.

である。In addition, by incorporating inert silica, the adhesive has a clay-like viscosity that does not change, and it always maintains a viscous adhesion to the surface and will not peel off from the surface due to vibrations, shocks, etc. It maintains its viscosity semi-permanently and can adhere tightly without allowing moisture or air to enter the gaps.

備え、すぐれた耐薬品性を備えている。Also, by mixing a small amount of tannin, the adhesive 11 forms a hard, dense film of iron tannate on the metal surface, and this film prevents the progress of rust, and together with the anticorrosive effect of petrolatum, prevents the progress of rust. The blocking effect is maintained semi-permanently, and the adhesive layer 13 has acid resistance, alkali resistance, salt resistance, and excellent chemical resistance.
