Construction method and structure of four-direction unbonded prestressed crossed beam-column joint
The invention discloses a construction method and structure of a four-direction unbonded prestressed crossed beam-column joint. The construction method comprises the following construction technological processes: a, hoisting construction of an assembly structure column; b, hoisting two longitudinal overlapped T beams under a plate in place, and carrying out crossed perforating operation on overhung unbonded prestressed tendons; c, hoisting two transverse overlapped T beams under the plate in place, and carrying out crossed perforating operation on the overhung unbonded prestressed tendons; d,connecting the longitudinal and transverse overlapped T beams under the plate with column steel bars; e, hoisting overlapped plates in place, and anchoring overhung steel bars of the overlapped plates into the overlapped beams; f, pouring and maintaining concrete on the whole surface layer of a post-pouring section; g, mutually crossing, tensioning and anchoring the unbonded prestressed tendons of the longitudinal and transverse overlapped T beams under the plate at the end parts of the sections of the T beams; and h, grouting prestressed ducts. According to the construction method and structure, the strength of the beam-column joint is improved, the earthquake resistance is good, and the construction method and structure play an important role in promoting the better construction of theconstruction industry in China.
本发明公开了一种四方位无粘结预应力交叉梁柱节点施工方法及构造，其施工工艺流程包括：a.装配结构柱吊装施工；b.板下纵向两叠合T梁吊装就位，外伸无粘结预应力筋交叉穿孔作业；c.板下横向两叠合T梁吊装就位，外伸无粘结预应力筋交叉穿孔作业；d.板下纵横双向叠合T梁与柱钢筋连接；e.叠合板吊装就位，叠合板外伸钢筋锚入叠合梁内；f.后浇段整体面层混凝土浇筑、养护；g.板下纵横双向叠合T梁无粘结预应力筋在T梁截面端部相互交叉张拉锚固；h.预应力孔道灌浆。本发明提高了柱梁节点强度，抗震性好，对推进我国建筑业更好转型具有重要作用。
