FRP-concrete prefabricated assembly combined structure

Abstract

The invention discloses a FRP-concrete prefabricated assembly combined structure. The FRP-concrete prefabricated assembly combined structure comprises an FRP-coral concrete structure column, an FRP-coral concrete structure beam, an FRP-coral concrete structure plate and an FRP-coral concrete structure wall; and the FRP-coral concrete structure column, the FRP-coral concrete structure beam, the FRP-coral concrete structure plate and the FRP-coral concrete structural wall are combined to use, and wherein the FRP-coral concrete structure column, the FRP-coral concrete structure beam, the FRP-coral concrete structure plate and the FRP-coral concrete structure wall are all composed of reinforcing pieces and coral concrete. According to the FRP-concrete prefabricated assembly combined structure,the field operation difficulty is greatly reduced, the project cost is saved, and the construction period is shortened; and moreover, the durability is good, the maintenance is easy, the later maintenance cost is saved, and meanwhile, local materials are obtained, so that the engineering construction difficulty is lowered.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an FRP-concrete prefabricated assembly structure. Background technique [0002] In areas such as coastal areas and remote sea islands and reefs, traditional reinforced concrete structures and steel structure projects have shortcomings such as serious corrosion and short maintenance periods. According to estimates, in 2009, the economic loss caused by corrosion in my country exceeded 1 trillion yuan, and 1.5 tons of steel were corroded every second. The corrosion loss of the marine industry accounts for about 1 / 3 of the country's total corrosion loss, reaching more than 600 billion yuan. Ocean engineering, especially construction projects on islands and reefs in the South China Sea far away from land, still faces technical difficulties such as difficult sea transportation of raw materials, high construction costs, long construction period, and poor structural durability.

Problems solved by technology

Ocean engineering, especially construction projects on islands and reefs in the South China Sea far away from land, still faces technical difficulties such as difficult sea transportation of raw materials, high construction costs, long construction period, and poor structural durability. Many inconveniences caused by resource development

[0003] The traditional reinforced concrete structure is severely corroded in the marine environment, especially in tropical islands and reefs (high temperature, high chloride ion content, high humidity), and it needs to be repaired and repaired in three or four years, and it needs to be rebuilt in about 10 years. Great waste of cost

[0004] In the construction of reinforced concrete projects on coastal or remote islands and reefs, the materials used, such as cement, sand, and stones, need to be transported from the inland to the destination. In addition to the materials, there is also mixing water, which requires precious fresh water resources and requires a lot of effort. Transportation at a high cost, especially in remote islands and reefs, has caused great economic burden and loss
