Post-tensioning-method unbonded prestressed-reinforcement under-plate T-beam flange tensioning node and construction method
The invention discloses a post-tensioning-method unbonded prestressed-reinforcement under-plate T-beam flange tensioning node and a construction method. The flow of the construction technology includes (1) cast-in-place concrete column reinforcement binding and formwork mounting construction, (2) overall floor and T-beam formwork support mounting, (3) beam-plate reinforcement binding and unbondedprestressed reinforcement layout, (4) under-plate T-beam flange end tip unbonded prestressed reinforcement treatment, (5) overall pouring of beam-plate column concrete and maintenance, (6) under-plateT-beam flange end tip unbonded prestressed reinforcement tensioning and anchoring, (7) prestressed reinforcement anchoring end sealing anchor treatment and (8) formwork support removal. According tothe node and the construction method, the under-plate T-beam flange end prestressed tensioning technology is adopted at the cast-in-place concrete beam column node, the stress characteristic of the beam column node is improved effectively, the node has the good hogging moment resisting effect, and the prestressed beam column reinforced node has the high shock resistance.
本发明公开了一种后张法无粘结预应力筋板下T梁翼板张拉节点及施工方法，其施工工艺流程包括：1)现浇混凝土柱钢筋绑扎及模板安装施工；2)楼板及T梁模板支架整体安装；3)梁板钢筋绑扎及无粘结预应力筋铺设；4)板下T梁翼板端头无粘结预应力筋处理；5)梁板柱混凝土整体浇筑及养护；6)板下T梁翼板端头无粘结预应力筋张拉、锚固；7)预应力筋锚固端封锚处理；8)模板支架拆除。本发明在现浇混凝土梁柱节点处采用板下T梁翼板端预应力张拉技术，有效改善了梁柱节点受力特性，节点抗负弯矩效果好，预应力梁柱增强节点抗震能力强。
