Special-shaped telescopic T-shaped box girder inner formwork supporting system and supporting method thereof
The invention provides a retractable and expandable box girder inner formwork supporting system, which is made of an aluminum alloy formwork, wherein the inner formwork is of an annular structure, thesupporting force is enhanced through the annular structure, the aluminum alloy formwork is good in stability and high in bearing capacity at the same time, and the overall rigidity can be greatly improved. The invention further provides a supporting method of the supporting system, which comprises the steps of fixing the bottom of the box girder formwork to a foundation, rotating lead screws, slowly opening the formwork, fixing the lead screws, and checking the formwork; and pouring concrete, rotating the lead screws to enable a supporting mechanism to contract, and finally removing the formwork. The annular inner formwork is arranged to be retractable, the formwork is opened and tightened to form an annular structure when being supported, the formwork is folded through the screws duringformwork removal, the annular structure is loosened, the formwork has a centripetal pull force when being loosened, the removal is facilitated, the formwork is still a whole after formwork removal, and the circulation is facilitated.
本发明提供一种可收缩、张开的箱梁内模支撑系统，采用铝合金模板制作，内模板为环状结构，利用环形结构增强支撑力，同时铝合金模板稳定性好、承载力高，能大大提高整体刚性。本发明还提供了一种上述支撑系统的支撑方法，先将箱梁模板底部固定在基础上，旋转丝杆，将模板缓慢张开，固定丝杆，检查模板。浇筑混凝土，旋转丝杆，使支撑机构收缩，最后移出模板。将环形内模设置为可收缩式，支撑时模板张开绷紧为环状结构，拆模时通过螺杆将模板折叠，环形结构松开，松开时模板有向心拉力，有助于拆除，拆模后模板仍为一个整体，便于周转。
