As a supporting bearing member for cable laying, steel bridges need to adapt to various load and span conditions, meet the mechanical performance requirements, and have a reasonable structure and less consumables.
Steel cable trays are generally used for group laying of multiple cables. After the cable is in place, it is often difficult to carry out surface anti-corrosion treatment on the metal bridge, so it is necessary to implement its factory one-time surface anti-corrosion treatment and set stricter and quantitative technical requirements according to the corresponding environment.
For projects with high safety expectations such as power plants, petrochemicals, metallurgical enterprises, or important building facilities, it is often necessary to consider the selection of the material of the bridge frame and the construction method from the requirements of preventing the cable from igniting or flaming.
In addition, it should meet certain specific standards and pass the necessary experimental verification.
The steel cable bridge structure system contains different classifications and series varieties and formations, so it is necessary to choose reasonably according to the engineering use conditions, and also require the product to meet the corresponding technical characteristics, allowable tolerances and other technical indicators.
Throughout the past engineering practice, although the application of most steel cable trays is fruitful, it is not a few quality problems. Such as collapse after assembly and use, severe corrosion in just a few years, some materials have poor fire resistance and fire resistance, and some engineering selections cause major defects. Some bridge products have poor materials, rough processing, weak solder joints, and anticorrosion Uneven layer adhesion and insufficient adhesion, etc. The reason is that the technical standards and legal certifications are not strictly enforced.
