The invention discloses a supporting device of a temporary support for bent cap construction and a construction method of the supporting device, and belongs to the technical field of bridge construction. The supporting device comprises a horizontal supporting rod, a surrounding connecting component and a vertical supporting rod. The surrounding connecting component is detachably connected with thehorizontal supporting rod through a clamping groove, an annular connecting bolt and a connecting bolt, a vertical supporting column is connected with the surrounding connecting component through a vertical connecting bolt and a sleeve, and devices such as a bent cap cast-in-place construction formwork are arranged on the vertical supporting rod. Cover beam construction load, temporary facility load, cover beam dead weight and the like are transmitted to the bridge pier column through the vertical supporting column, the surrounding connecting component and the horizontal supporting rod. The bent cap construction device designed by the invention has the advantages of high shear bearing capacity, high anti-overturning bearing capacity, convenience and safety in construction, high construction efficiency, high recycling rate, stable construction quality and the like.

本发明的盖梁施工临时支架的支撑装置及其施工方法属于桥梁施工技术领域，支撑装置包括水平支撑杆、环抱连接构件和竖向支撑杆。环抱连接构件通过卡槽、环向连接栓以及连接螺栓与水平支撑杆可拆卸连接，竖向支撑柱与环抱连接构件通过竖向连接栓和套筒连接，盖梁现浇施工模板等装置置于竖向支撑柱上，盖梁施工荷载、临时设施荷载、盖梁自重等通过竖向支撑柱、环抱连接构件以及水平支撑杆传递至桥梁墩柱。本发明设计的盖梁施工装置具有高抗剪承载力、高抗倾覆承载力、施工方便、安全、施工效率高、可循环率高、施工质量稳定等优点。
