Crack-control anti-corrosion prefabricated steel-concrete composite comprehensive pipe rack
The invention discloses a crack-control anti-corrosion prefabricated steel-concrete composite comprehensive pipe rack. A comprehensive pipe rack structure is formed by splicing composite prefabricatedparts through casting ultrahigh-toughness cement-based composite materials in place. Two bottom prefabricated parts and one top prefabricated part are transversely spliced to form an arch-shaped section of the structure, and the structure longitudinally achieves the length meeting the design requirement by continuously splicing formed arch-shaped section units; and the prefabricated parts adopt steel-concrete composite cross sections and are composed of profile steel arches, reinforced concrete plates and shear connectors, grooves are reserved in structural hogging moment areas on the reinforced concrete plates, and after the prefabricated parts are assembled, the ultrahigh-toughness cement-based composite materials are cast in place in the grooves, so that transverse and longitudinal connection between the prefabricated parts is achieved. The comprehensive pipe rack is excellent in structure bearing performance and high in assembly degree and has excellent crack control and anti-corrosion properties, and the structural cost is reduced by reasonably arranging the ultrahigh-toughness cement-based composite materials.
本发明公开了一种控裂防腐蚀的装配式钢‑混凝土组合综合管廊，综合管廊结构由组合预制件通过现浇超高韧性水泥基复合材料拼接而成。结构横向由两个底部预制件和一个顶部预制件拼装形成拱形截面；结构纵向通过将形成的拱形截面单元连续拼装达到满足设计需求的长度。预制件采用钢‑混凝土组合截面，由型钢拱、钢筋混凝土板、剪力连接件组成。钢筋混凝土板上的结构负弯矩区留有凹槽，预制件拼装后在凹槽中现浇超高韧性水泥基复合材料，以实现预制件之间的横向和纵向连接。本发明提出的综合管廊结构承载性能优越，装配化程度高，拥有优越的控裂防腐蚀属性，通过合理布置超高韧性水泥基复合材料降低结构成本。
