Concrete V-shaped rigid frame bridge construction support and construction method
The invention discloses a concrete V-shaped rigid frame bridge construction support and a construction method. The support comprises a hasp support arranged at the V-leg forking position of the V-shaped pier, a pair of bottom die support trusses symmetrically arranged on the two sides of the hasp support, a top die supporting beam arranged at the top of the hasp support, a pair of buckle cable systems connecting the pair of bottom die supporting trusses and the buckle tower support, and a pair of construction platforms arranged on the outer sides of the pair of bottom die support trusses. The bottom formwork supporting trusses are used for inclined leg pouring of a V-shaped rigid frame bridge, the top formwork supporting beams are used for pouring of an upper beam body, the bottoms of the bottom formwork support trusses are hinged to the ends of V legs of V-shaped piers, the middles of the bottom formwork support trusses are connected to the buckling tower supports through buckling cable systems, and the pair of bottom formwork support trusses are further connected into a whole through positioning pieces. The construction platform is arranged in the projection range of the V-shaped rigid frame bridge. The bracket is assembled by a profile steel structure, and has the advantages of stable structure, high applicability, low cost, capability of meeting the construction requirements on the strength and rigidity of the bracket and the like.
本发明公开了一种混凝土V形刚构桥施工支架及施工方法，支架包括设置于V形墩的V腿分叉处的搭扣支架、对称设置于搭扣支架两侧的一对底模支架桁架、设置于搭扣支架顶部的顶模支撑梁、连接一对底模支撑桁架与扣塔支架的一对扣索系统以及设置于一对底模支架桁架外侧的一对施工平台，所述底模支撑桁架用于V形刚构桥的斜腿浇筑，所述顶模支撑梁用于上部梁体浇筑，所述底模支架桁架底部分铰接于V形墩的V腿端部，中部通过扣索系统连接至所述扣塔支架上，一对底模支架桁架之间还通过定位件连接为一体，所述施工平台设置于V形刚构桥投影范围内。本发明支架采用型钢结构组拼，具有结构稳定、适用性强、成本低、支架强度刚度均满足施工要求等优点。
