Prestressed concrete annular supporting column for electronic railway connecting net plane
The invention discloses a prestressed concrete annular supporting column for an electronic railway connecting net plane. The prestressed concrete annular supporting column comprises ultra-high-performance concrete and a skeleton, the skeleton is poured in the ultra-high-performance concrete and comprises a plurality of main ribs and a plurality of annular positioning sheets, the annular positioning sheets are distributed in the length direction of the main ribs at equal intervals, a plurality of positioning holes are circumferentially and evenly formed in the annular positioning sheets, and the main ribs are arranged in the positioning holes in one-to-one correspondence and penetrating modes. The structure of the annular supporting column is significantly simplified, the position deviationand eccentric error of the main ribs are reduced, thus the intervals of the main ribs keep consistent, stress of the annular supporting column is uniform, the strength of the annular supporting column is improved, and the crack phenomenon of the annular supporting column is relieved.
本发明公开了一种电气化铁路接触网预应力混凝土环形支柱，包括超高性能混凝土和骨架，所述骨架被浇筑在所述超高性能混凝土中，所述骨架包括若干个主筋和若干个环形定位片，所述环形定位片沿所述主筋的长度方向等间距分布，所述环形定位片周向均匀开设有若干个定位孔，所述主筋一一对应穿设在所述定位孔中。本发明使环形支柱结构显著简化，并减小主筋的位置偏差以及偏心误差，使主筋间距保持一致，从而达到环形支柱受力均匀，提高环形支柱的强度，改善环形支柱出现裂纹的现象。
