Construction method of large-span variable-cross-section cantilever oblique beam
The invention provides a large-span variable-cross-section cantilever oblique beam construction method which comprises the steps that L-shaped angle iron is welded and fixed to the bottom of a main keel of an oblique beam formwork support, so that the bottom of the main keel welded with the L-shaped angle iron is a horizontal plane, then a vertical rod jacking is tightly attached to the bottom of the main keel, and in the concrete pouring process, the vertical rod jacking is tightly attached to the bottom of the main keel; and the load at the upper part can be uniformly transmitted to the vertical rod. The technical problems that an existing large-span variable-cross-section oblique beam formwork support is large in erecting difficulty, and overhanging floor slabs are large in elevation and difficult to position accurately are solved. Belongs to the technical field of building structure engineering.
本发明提供一种大跨度变截面悬挑斜梁施工方法，该方法是在斜梁支模架的主龙骨的底部焊接固定“L”型角铁，以使焊接“L”型角铁后的主龙骨底部为水平面，再将立杆顶托与主龙骨底部紧密贴合，在混凝土浇筑过程中，使上部的荷载能够均匀的传递至立杆。以解决现有大跨度变截面斜梁支模架搭设难度大，及悬挑楼板标高较多，难精准定位的技术问题。属于建筑结构工程技术领域。
