Construction method of prefabricated pier column vertical rotation formwork
The invention discloses a construction method of a prefabricated pier column vertical rotation formwork, which belongs to the technical field of bridge construction and comprises the following steps: assembling a formwork mechanism on a formwork assembling pedestal, fixing one end of the formwork mechanism on a formwork fixing beam after the assembling is finished, connecting the formwork fixing beam to a vertical rotation pedestal through a rotating shaft, and fixing the formwork mechanism on the vertical rotation pedestal through the rotating shaft; a temporary hoisting block is installed at the other end of the formwork mechanism and used for hoisting the formwork mechanism; a lifting device is installed on the temporary lifting block, slow lifting is conducted, so that the formwork mechanism drives the formwork fixing beam to clockwise rotate by 90 degrees around the rotating shaft, and the formwork fixing beam falls on the vertical rotating pedestal; and after the formwork mechanism is vertically placed and stabilized, bolts between the formwork mechanism and the formwork fixing beam are dismantled, the formwork mechanism is integrally hoisted to a pouring pedestal to be fixed, the temporary hoisting blocks are dismantled, and concrete pouring construction is conducted. The advantages of horizontal construction and vertical construction are ingeniously combined, the safety during formwork assembly is improved, and the apparent quality of concrete is guaranteed.
本发明公开了一种预制墩柱竖向转体模架的施工方法，属于桥梁施工技术领域，包括如下步骤：在模板拼装台座上拼装模板机构，待拼装结束后，将模板机构的一端固定在模板固定梁上，模板固定梁通过转轴连接在竖向转体台座上，在模板机构的另一端安装临时吊装块，用于吊升模板机构；将起吊装置安装到临时吊装块上，缓慢拉升使模板机构带动模板固定梁绕转轴顺时针转动90度，使模板固定梁落在竖向转体台座上；将模板机构竖直安放稳定后，拆除其与模板固定梁之间的螺栓，将模板机构整体吊装至浇筑台座上固定，拆除临时吊装块，进行混凝土浇筑施工。本发明巧妙的结合了卧式施工及竖直施工的优点，既提升了模板拼装时的安全性，又保证了混凝土的表观质量。
