Shock-resistant steel-bar concrete structure side coal bunker

Abstract

The invention provides a shock-resistant steel-bar concrete structure side coal bunker which comprises frame columns and frame beams. The shock-resistant steel-bar concrete structure side coal bunker is characterized in that the frame columns and the frame beams are respectively internally provided with steel bars, so as to form frame column steel bars and frame beam steel bars; the frame column steel bars are connected with the frame beam steel bars so as to form a steel framework; the parts, which correspond to the frame column steel bars and the frame beam steel bars, of the periphery of the steel framework are respectively bound with frame column steel ribs and frame beam steel ribs; the frame columns and the frame beams are respectively and internally filled with concrete inner cores, so that a steel-bar concrete frame is formed; the steel-bar concrete frame is provided with buckling restrained braces in a transverse direction and a longitudinal direction respectively. The shock-resistant steel-bar concrete structure side coal bunker achieves the technical purposes of reducing component sections, quickening the construction speed, improving the structural shock resistance and the like, can be used for saving construction materials, reducing the consumption of cement, gravel, sand, steel products and water and saving land, can be rapidly put into production again by virtue of simple maintenance after being subjected to great shock, so that the electric power supply is guaranteed and the society stability maintained.

Description

technical field [0001] The invention relates to a side coal bunker structure in a thermal power plant, in particular to a side coal bunker with a high strength anti-seismic steel-reinforced concrete structure. Background technique [0002] In some thermal power plants that have been built or newly built, in order to reduce the length of the four major pipelines (main steam pipeline, reheat cold pipeline, reheat hot pipeline, and main water supply pipeline) between the turbine and the boiler, side coal bunkers are often used in process layout. scheme, and gradually become the mainstream layout scheme. Because the four major pipelines are high-temperature and high-pressure pipelines with expensive materials, they occupy a large share of the investment in thermal power plants. Coal conveying belts, coal hoppers, coal feeders, etc. are arranged in the side coal bunker, and coal mills are arranged at zero meters. Among them, the load of the coal hopper part is very large,...

AI Technical Summary

Problems solved by technology

Some power plants also use steel structures for the side coal bunkers, which have better ductility and excellent seismic performance, but compared with reinforced concrete structures, the cost is too high, and there are many problems in fire protection
