T-girder flange slab tensioning joint under post-tensioned bonded prestressed ribbed slab and construction method
The invention discloses a T-girder flange slab tensioning joint under a post-tensioned bonded prestressed ribbed slab and a construction method. The construction process flow comprises the following steps of 1) binding of cast-in-place concrete column steel bars and template mounting construction; 2) integral installation of a floor and a T-girder template bracket; 3) girder slab steel bar bindingand prestressed rib pipe insertion pavement; 4) pipe insertion treatment of T-girder flange slab end prestressed ribs under slabs; 5) overall casting and maintenance of slab column concrete; 6) tensioning and anchoring of prestressed ribs at the ends of T-girder flange slabs under the slabs; 7) passageway grouting and prestressed rib anchoring end anchor-sealing treatment; and 8) disassembly of the template bracket. According to the construction method, an under-slab T-girder flange slab end prestressed tensioning technology is adopted at a cast-in-place concrete beam-column joint, so that the beam-column joint stress characteristic is improved effectively; the joint is high in hogging moment resistance; and the prestressed beam-column reinforced joint is high in shock resistance.
本发明公开了一种后张法有粘结预应力筋板下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）梁板钢筋绑扎及预应力筋穿管铺设；4）板下T梁翼板端头预应力筋穿管处理；5）梁板柱混凝土整体浇筑及养护；6）板下T梁翼板端头预应力筋张拉、锚固；7）孔道灌浆及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。
