Difficult-to-corrode steel structure

Abstract

The invention discloses a difficult-to-corrode steel structure, which comprises a left side steel plate, a right side steel plate, a stainless steel sleeve and a fixing screw, wherein the left side steel plate, the stainless steel sleeve and the right steel plate are in sequential arrangement from the left side to the right side; each of the left side steel plate and the right side steel plate isof a rectangular plate-shaped structure; and round chamfers are arranged in the edge positions of the left side steel plate and the right side steel plate. The round chamfers are arranged in the edgepositions of the left side steel plate and the right side steel plate in the device, so that the abrasion is small; paint in the edge positions cannot be easily scraped away, so that building steel cannot be corroded by moisture in the air and rainwater; the building steel cannot easily rust; high structure intensity can be maintained; the safety is high; a corresponding sealing device is arrangedin the stainless steel sleeve; a sealing ring is also arranged in a screw cap position of the fixing screw; the sealing performance in a connecting position of the screw connecting position and the building steel is good; the abrasion cannot easily occur; the paint protection is good; the building steel cannot easily rust; the connecting intensity between the building steel can also be correspondingly improved; the service life is long; and the difficult-to-corrode steel structure is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a steel structure that is not easily corroded. Background technique [0002] Compared with traditional concrete buildings, steel structure buildings use steel plates or section steel instead of reinforced concrete, which has higher strength and better earthquake resistance. And because the components can be manufactured in a factory and installed on site, the construction period is greatly reduced. Due to the reusable use of steel, it can greatly reduce construction waste and be more environmentally friendly, so it is widely adopted by countries all over the world and used in industrial buildings and civil buildings. However, the following disadvantages still exist in the actual use of building steel structures: [0003] 1. The building steel structure is eroded by moisture or rainwater in the process of use. The building steel will corrode after long-term use,...

AI Technical Summary

Problems solved by technology

[0003] 1. The building steel structure is eroded by moisture or rainwater in the process of use. The building steel will corrode after long-term use, and the strength of the corroded building steel structure will decrease accordingly, posing safety hazards;

[0004] 2. The joints of construction steel tend to wear each other. After the wear, the paint on the surface of construction steel will fall off, which will accelerate the corrosion of construction steel, the service life will be shorter, and the connection strength between construction steel will also decrease accordingly.
