Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of uneven application, difficult quality control, large environmental impact, and low work efficiency when using artificial preservatives to anti-corrosion bolts. Complicated and relatively high-cost defects, providing a cost-effective bolt anti-corrosion method that is not only simple in steps and easy to operate, but also does not need to be coated with preservatives, can be formed on-site

Embodiment 1

[0031] Such as Figure 1-7 Shown, what the bolt anticorrosion method of the present invention uses is anticorrosion tape, and during operation, anticorrosion tape is covered on such as figure 1 Bolt stud 1 and bolt cap 2 shown. In this embodiment, two parts of anti-corrosion tape are used, one part is to cut the anti-corrosion tape and cover it on the bolt stud 1, and the other part is to directly wrap the anti-corrosion tape on the bolt stud 1 and the bolt cap 2.

[0032] During the specific operation, firstly, the anticorrosion tape needs to be cut into bolt stud stickers, and the cutting process is as follows: cutting the round anticorrosion tape, and then cutting the round anticorrosion tape into bolt stud stickers. The diameter of the circular anticorrosion tape is D=D 柱 +L, and the 0长 , where the D 柱 is the diameter of the stud column, the L 长 is the length from the end face of the bolt stud to the bolt cap. The value of the diameter D in this embodiment is D=D 柱 +...

Embodiment 2

[0038] Such as Figure 8 , 9 As shown, in this embodiment, the anticorrosion tape is directly wrapped around such as figure 1Sealing is performed on the bolt stud 1 and the bolt cap 2 shown, without cutting the stud stud sticker in Embodiment 1. At the same time, the winding method in this embodiment is the same as in Embodiment 1. The anti-corrosion tape is wound at least twice, the first winding is wound with a tensile force of 1.5 to 3 times the original length, and the second winding is wound with a tensile force less than 1.5 times the original length. Stretch for winding. When winding, the anti-corrosion tape covers the end face and side of the entire bolt stud 1, such as Figure 8 As shown, the anti-corrosion tape covers at least the upper end face and the side of the bolt cap. Since the diameter of the bolt stud 1 is smaller than the diameter of the bolt cap 2, the remaining anti-corrosion tape can be folded inward after winding half a circle. In this embodiment, ...

Abstract

The invention discloses a corrosion preventing method for bolts. The corrosion preventing method is characterized in that an anti-corrosive tape is wound on a bolt stud and a bolt cap, the anti-corrosive tape is elastic and can be stretched, the first circle of anti-corrosive tape is wound with tensile strength enabling the length of the anti-corrosive tape to be 1.5-5 times of original length, and the second circle of anti-corrosive tape is wound with tensile strength enabling the length of the anti-corrosive tape to be smaller than 1.5 times of original length. The steps are simple and are convenient to operate. The anti-corrosive tape does not need to be coated with an anti-corrosive agent when used, the anti-corrosive agent on the inner layer of the anti-corrosive tape is evenly distributed on the surfaces of the bolt and the bolt cap under the action of winding tightening force in the winding process, and in this way, an anti-corrosive protecting layer in a compound structure is formed on the surfaces of the bolt and the bolt cap. Therefore, the corrosion preventing method is suitable for popularization and use.

Description

technical field [0001] The invention relates to construction, in particular to a bolt anticorrosion method. Background technique [0002] Bolt is the most widely used fastener, known as the rice of industry. Vital task industrially born by bolt, as long as there is industry on the earth, then the function of bolt will be the most important. Due to the complexity of the environment, the corrosion of bolts is not optimistic. Bolts that have been used for a long time often have corrosion and bonding between the bolt post and the bolt cap sleeve. During maintenance, a nut splitter must be used to deal with it. What’s more, the bolt post is corroded and broken, causing accidents. . [0003] At present, there are two methods for bolt anticorrosion: smearing antiseptics (such as butter, antiseptic grease or antiseptics) and wearing nuts. The method of smearing preservatives is usually manual smearing, which has the disadvantages of uneven smearing, difficult quality control, gre...
