Pier prefabricated spliced viaduct capable of shortening construction period
The invention relates to a pier prefabricated spliced viaduct which comprises a bridge plate and a plurality of piers supporting the bridge plate, each pier comprises sections distributed in the vertical direction and connected together through a plurality of inserting structures, and each inserting structure comprises a steel thread head located on the lower section and an upper steel thread head located on the upper section. The lower steel thread head is in threaded connection with the interior of a steel internal thread sleeve provided with a steel connecting cylinder, the upper thread head is in threaded connection with a connecting steel sleeve, the steel connecting cylinder is arranged in the connecting steel sleeve in a penetrating mode, the steel connecting cylinder is provided with a clamping ring groove, an inclined bottom sliding groove is formed in the inner circumferential face of the connecting steel sleeve, and a steel barb is connected in the inclined bottom sliding groove in a sliding mode. A barb downward moving spring for driving all the steel barbs to slide downwards is arranged in the connecting steel sleeve, and the steel barbs are hooked in the clamping ring grooves. The viaduct has the advantage that the construction period can be shortened, and the problems that due to the fact that piers of an existing viaduct are of a cast-in-place structure, the construction period is long when the piers are high, and formwork supporting frames are inconvenient to build are solved.
本发明涉及一种桥墩预制拼接式高架桥，包括桥板和支撑桥板的若干桥墩，桥墩包括沿上下方向分布的通过若干个插接结构连接在一起的分段，插接结构包括位于下方的分段的钢螺纹头和位于上方的分段的上钢螺纹头，下钢螺纹头螺纹连接在设有钢连接圆柱的钢内螺纹套筒内上，上螺纹头上螺纹连接有连接钢套，钢连接圆柱穿设在连接钢套内，钢连接圆柱设有卡接环槽，连接钢套的内周面上设有斜底滑槽，斜底滑槽内滑动连接有钢倒钩，连接钢套内设有驱动所有的钢倒钩朝下滑动的倒钩下移弹簧，钢倒钩钩接在卡接环槽内。本发明具有能够缩短施工周期的优点，解决了现有的高架桥的桥墩为现浇结构导致的桥墩高时施工周期长且搭建模板支撑架时不便的问题。
