Post-tensioning method bonded prestress tensioning groove optimization structure and construction method thereof
The invention discloses a post-tensioning method bonded prestress tensioning groove optimization structure and a construction method thereof. The optimization structure comprises a prestressed beam, a tensioning side beam arranged at one end of the prestressed beam and tensioning ribs arranged in the prestressed beam and the tensioning side beam. Through the arrangement of the tensioning side beam, on one hand, the tensioning end originally arranged at the prestressed beam end extends to the tensioning side beam, and a reinforcing steel bar dense area at the beam end is avoided; on the other hand, a tensioning foundation is provided for prestress tensioning; a tensioning groove is formed through the arrangement of a tensioning side beam table and a tensioning side channel beam, convenient tensioning is achieved, and the tensioning operation space is guaranteed; and through the arrangement of the dense stirrups and the obliquely-inserted steel bars, reinforcement of the tensioning end is further guaranteed, and the strength of the beam body at the tensioning position can be improved.
本发明公开了一种后张法有粘结预应力张拉槽优化结构及其施工方法，优化结构包含预应力梁、设置于预应力梁一端的张拉侧梁以及设置于预应力梁内部和张拉侧梁内部的张拉筋。本发明通过张拉侧梁的设置，一方面将原本在预应力梁端的张拉端延伸至张拉侧梁处，避开了梁端的钢筋密集区；另一方面为预应力张拉提供了张拉基础；过张拉侧梁台和张拉侧槽形梁的设置，形成了张拉槽，实现了便捷张拉和保证了张拉的操作空间；通过加密箍筋和斜插钢筋的设置，进一步保证了张拉端的加固，利于提高张拉处梁体的强度。
