The invention discloses a stay cable combined type tension support and a construction method. The stay cable combined type tension support comprises an outer support, an inner support and a connecting bolt. The outer support and the inner support are installed at the tensioning position inside a box girder, one end of the inner support makes contact with a main beam anchor bearing plate, the other end of the inner support is connected with one end of the outer support through a connecting bolt, the outer support and the inner support are combined to form a stay cable combined tensioning support, and the tensioning jack is installed at the other end of the outer support to conduct tensioning operation. The stay cable combined type tension support can be detached into two parts, the detached tension support is small in weight, convenient to move, capable of adapting to operation in a narrow space in a box girder, easy to manufacture, convenient to construct and operate, good in construction safety and low in cost, and the construction method based on the support has the advantages that the construction efficiency is high, and the construction cost is low. According to the construction method based on the supports, the problems that in the prior art, due to the fact that an integral tensioning support is used for tensioning the stay cable, the construction speed is low, construction is not easy to operate, the safety risk is large, and the use cost is increased are solved, and the application prospect is good.
本发明公开了一种斜拉索组合式张拉支座及施工方法，斜拉索组合式张拉支座，包括外支座、内支座和连接螺栓；外支座和内支座安装在箱梁内部张拉位置，其中内支座的一端与主梁锚垫板接触，另一端通过连接螺栓与外支座的一端连接，外支座和内支座组合成斜拉索组合式张拉支座，外支座的另一端安装有张拉千斤顶以进行张拉作业。本发明的斜拉索组合式张拉支座，可拆分为两部件，分后的张拉支座重量小，移动方便，能适应箱梁内部狭小空间作业且制作简单，施工操作方便，施工安全性好，成本低廉，基于支座的施工方法，解决了现有技术中使用整体式张拉支座来张拉斜拉索引起的施工速度慢、施工不易操作、安全风险大、使用成本增加的问题，极具应用前景。
