Prefabricated lattice beam secondary anchor cable tensioning steel reinforced concrete node structure and construction method
The invention discloses a prefabricated lattice beam secondary anchor cable tensioning steel reinforced concrete joint structure and a construction method. Comprising the construction steps of production of a prefabricated lattice beam, excavation of a beam groove, installation of the prefabricated lattice beam, installation of a section steel framework on the lower portion of a cross-shaped overlapped joint, installation of a section steel framework on the upper portion of the cross-shaped overlapped joint, binding of steel bars at the position of the cross-shaped overlapped joint, construction and primary tensioning of an anchor cable, pouring of overlapped concrete, secondary tensioning of the anchor cable, backfilling, greening and the like. The prefabricated lattice beam reserved ribs and the profile steel framework are subjected to penetrating or bending treatment, and studs are welded to the inner side and the outer side of the profile steel framework, so that the integrity of the prefabricated lattice beam and the cross-shaped overlapped joint part is effectively improved; the secondary tensioning anchor cables are tensioned for the first time after the prefabricated lattice beams and the profile steel framework are installed, the protection slope can be protected to a certain degree through primary tensioning, the time of the side slope in the non-support exposed state is greatly shortened, safety in the side slope construction process is effectively guaranteed, and risks existing in the construction process are reduced.
本发明公开了一种预制格构梁二次锚索张拉型钢混凝土节点结构及施工方法，包括预制格构梁生产、梁槽开挖、预制格构梁安装、十字叠合接头下部型钢骨架安装、十字叠合接头上部型钢骨架安装、十字叠合接头部位钢筋绑扎、锚索施工及一次张拉、叠合混凝土浇筑、锚索二次张拉、回填及绿化等施工步骤；预制格构梁预留筋与型钢骨架进行贯穿或弯折处理，并于型钢骨架内外侧焊有栓钉，有效提高预制格构梁与十字叠合接头部位的整体性；二次张拉锚索在预制格构梁及型钢骨架安装后进行初次张拉，初次张拉即可对护坡形成一定防护，大幅度减少边坡无支护裸露状态时间，有效保证了边坡施工过程中的安全性，减少施工过程中存在的风险。
