Corbel joint for fabricated concrete canopy of railway passenger station
The invention discloses a corbel joint for a fabricated concrete canopy of a railway passenger station. The corbel joint comprises prefabricated concrete canopy beams, boundary beam corbel supports, boundary beam corbels, support cushion blocks, boundary beams, prefabricated concrete canopy top plates, horizontal haunches and corbel U-shaped stress ribs. The boundary beams are arranged on one sides of the prefabricated concrete canopy top plates, the boundary beam corbels are arranged at the two ends of the boundary beams, and the integrally-formed horizontal haunches are arranged at the positions adjacent to the boundary beam corbels; the boundary beam corbel supports and the support cushion blocks are symmetrically arranged at the two ends of the precast concrete canopy beams; and the corbel U-shaped stress ribs are horizontally arranged in the boundary beam corbel supports and the boundary beam corbels. The horizontal haunches are adopted at the width change joints of the boundary beams and the boundary beam corbels for smooth transition, sudden changes of the section are avoided, and stress concentration is prevented. The boundary beam corbels and the boundary beam corbel supports are anchored and connected with main beams by additionally arranging the U-shaped stress ribs, the stress performance of the corbel supports is improved, field installation is convenient, good economic benefits and social benefits are achieved, and the corbel joint is suitable for application and popularization.
本发明公开了一种用于铁路客站装配式混凝土雨棚的牛腿节点，包括预制混凝土雨棚梁、边梁牛腿支座、边梁牛腿、支座垫块、边梁、预制混凝土雨棚顶板、水平加腋和牛腿U型受力筋；预制混凝土雨棚顶板一侧设置有边梁，边梁两端均设有边梁牛腿，与边梁牛腿相邻处设有一体成型的水平加腋；预制混凝土雨棚梁两端对称设有边梁牛腿支座和支座垫块；边梁牛腿支座和边梁牛腿内部均水平设有牛腿U型受力筋。边梁和边梁牛腿宽窄变化连接处采用水平加腋平滑过渡，避免截面突变，防止应力集中。边梁牛腿和边梁牛腿支座通过增加U型受力筋与主梁进行锚固连接，提高牛腿支座的受力性能，现场安装方便，有良好的经济效益和社会效益，适合推广使用。
