Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a carbon fiber composite material pipe gallery frame. Background Art
[0002] A pipe gallery is a structure used to support and manage various pipelines, cables, and other facilities. It is widely used in many fields such as urban underground integrated pipe galleries, industrial facilities, power systems, communication networks, and building interiors. The design of the pipe gallery is to achieve an orderly layout of pipelines, improve space utilization, and facilitate maintenance and repair work. Carbon fiber is known for its excellent strength and rigidity, which enables the carbon fiber pipe gallery to maintain stable performance while bearing high loads. Carbon fiber is about four to five times stronger than steel, but its weight is only one-quarter of steel, which means that the carbon fiber pipe gallery has a higher cost-effectiveness at the same strength. Traditional steel pipe galleries are usually heavier, which increases the cost of installation and transportation. Carbon fiber pipe galleries can effectively reduce these costs due to their lightweight characteristics. Carbon fiber pipe galleries have excellent corrosion resistance because they do not contain metal components and are therefore not affected by oxidation and corrosion. This is especially important for use in harsh environments or in areas containing corrosive liquids. In high temperature environments, traditional steel pipe galleries may deform or degrade in performance. The carbon fiber pipe gallery can also maintain its physical properties unchanged in high temperature environments, solving this problem. Carbon fiber pipe racks have high fatigue strength and creep resistance, which means they can work stably for a long time, reducing the frequency of maintenance and replacement, thereby improving the reliability and life cycle of the entire system.
