Temporary prestress tensioning device for assembling precast concrete segment box girder
The invention discloses a temporary prestress tensioning device used during assembly of prefabricated concrete segment box girders, and relates to the technical field of bridge construction. According to the temporary prestress tensioning device for assembling the precast concrete segment box girders, through cooperation of the bearing plate frame and the connecting shaft rods on the two sides, the two adjacent box girder bodies can be tensioned through the connecting shaft rods along with outward movement of the bearing plate frame, and the two adjacent box girder bodies are supported through the bearing assembly until the tensioning prestress is met; at the moment, the relative acting force can act on the bearing assembly, compared with a traditional tensioning mode, convenience and stability of construction can be guaranteed, meanwhile, the phenomenon that disassembly is difficult due to too large stress can be avoided, and recycling is facilitated.
本发明公开了一种用于预制混凝土节段箱梁拼装时的临时预应力张拉装置，本发明涉及桥梁施工技术领域。该用于预制混凝土节段箱梁拼装时的临时预应力张拉装置，通过承重板架与两侧的衔接轴杆的配合，随着承重板架向外侧移动，能够通过衔接轴杆对相邻两个箱梁本体进行张拉，直至张拉预应力满足后通过承重组件进行支撑，此时相对的作用力能够作用在承重组件上，相较于传统的张拉方式，能够保证施工的便捷性以及稳定性，同时能够避免受力过大导致出现难以拆卸的现象，便于进行循环使用。
