The invention discloses a prestressed concrete transverse web member type strut for an electrified railway contact network. The prestressed concrete transverse web member type strut comprises ultra-high performance concrete and a plurality of arch frames, the plurality of arch frames are poured in the ultra-high performance concrete from bottom to top; each arch frame comprises two groups of arch-shaped structures; each arch-shaped structure comprises an annular frame and two V-shaped frames; the two V-shaped frames are fixed to the two ends of the annular frame respectively, the two V-shapedframes are symmetrical about the center of the annular frame, the two sets of arch-shaped structures are arranged in parallel and fixedly connected through a plurality of vertical short ribs, and thecentral axes of the annular frame bodies of the two sets of arch-shaped structures are located on the same vertical line. The overall strength and rigidity of the transverse web member type strut areimproved, stress distribution is uniform, and cracks are controlled at the source of structural design.
本发明公开了一种电气化铁路接触网预应力混凝土横腹杆式支柱,包括超高性能混凝土和多个弓形架,多个所述弓形架由下向上均被浇筑在所述超高性能混凝土中,所述弓形架包括两组弓形结构,所述弓形结构包括环形架和两个V形架,两个所述V形架分别固定在所述环形架的两端,两个所述V形架关于所述环形架的中心对称,两组所述弓形结构平行设置且利用若干个竖直短筋固定连接,两组所述弓形结构的所述环形架的中心轴线均在位于同一条竖直线上。本发明使横腹杆式支柱的整体强度、刚度提升,受力分布均匀,以在结构设计源头控制裂纹出现。
