Device for temporary prestress tensioning of segmental beam and construction method
The invention relates to a device for temporary prestress tensioning of segmental beams and a construction method, and relates to the technical field of auxiliary tools for bridge construction, the device comprises a hoisting mechanism, the hoisting mechanism comprises two segmental beam lifting appliances arranged at intervals in the assembling direction of the segmental beams, and the segmental beam lifting appliances are in one-to-one correspondence with the segmental beams and are used for connecting the segmental beams; the anchoring mechanism is arranged on the segmental beam lifting appliance, an inserting assembly is arranged on the anchoring mechanism, and the inserting assembly is used for being inserted into the segmental beam with the matched notch; and the tensioning mechanism is connected with the corresponding anchoring mechanisms on the two segmental beams so as to provide temporary prestress. Due to the fact that the anchoring mechanism is directly connected with the segmental beam lifting appliance, only the segmental beam needs to be provided with the matched notch to be connected with the inserting assembly, other construction holes in the segmental beam are universal lifting holes in the lifting process, arrangement of embedded parts is reduced, materials needed for blocking the holes are reduced, and the problems that in the prior art, a lot of materials need to be consumed for blocking the holes, and the construction cost is reduced are solved. The installation is troublesome, and the construction efficiency is reduced.
本申请涉及一种用于节段梁临时预应力张拉的装置及施工方法，涉及桥梁施工辅助工装技术领域，包括吊装机构，其包括两个沿节段梁拼装方向间隔设置的节段梁吊具，节段梁吊具与节段梁一一对应，用于连接节段梁；锚固机构，其设置在节段梁吊具上，锚固机构上设有插接组件，插接组件用于插接在已开配合槽口的节段梁上；张拉机构，其与两个节段梁上对应的锚固机构连接，以提供临时预应力。由于锚固机构直接与节段梁吊具连接，只需在节段梁上开配合槽口与插接组件连接，其余在节段梁上的施工孔为吊装过程中通用的吊装孔，减少了预埋件的设置，减少了封堵孔洞需要的材料，解决了现有技术中需要耗费不少材料封堵孔洞，存在安装麻烦，降低施工效率的问题。
