Construction method of large-span curved bridge deck slab
The invention relates to a large-span curve type bridge deck slab construction method which comprises the following steps: acquiring survey data of an installation site and design drawing data of multiple sections of steel beams, and establishing an entity installation model; a splicing jig frame correspondingly connected with the multiple sections of steel beams is established in the entity installation model, and the splicing jig frame comprises a jacking, a jig frame body and a pedestal from top to bottom; adjusting installation parameters of the plurality of splicing jig frames so as to enable a simulation curve formed by splicing the steel beams on the splicing jig frames to be matched with a design curve; recording installation parameters of a plurality of splicing jig frames corresponding to the simulation curve to form splicing data; and based on the splicing data, multiple sections of steel beams are installed through the splicing jig frame. According to the method, the simulation installation parameters of the splicing jig frame are obtained to be the same as the actual installation parameters, then the splicing jig frame is arranged according to the installation parameters, and then the splicing jig frame is used for actually installing the multiple sections of steel beams, so that the pre-camber and linearity of the large-span curve type steel beams meet the design requirements, and the adjustment process is reduced.
本申请涉及一种大跨度曲线型桥面板施工方法，其包括以下步骤：获取安装现场的勘测数据和多段钢梁的设计图纸数据，并建立实体安装模型；在实体安装模型中建立与多段钢梁对应连接的拼接胎架，拼接胎架从上至下包括顶托、胎架和台座；调整多个拼接胎架的安装参数，以使拼接胎架上钢梁拼接形成的模拟曲线与设计曲线相吻合；记录模拟曲线对应的多个拼接胎架的安装参数，形成拼接数据；基于拼接数据，利用拼接胎架安装多段钢梁。从而得到拼接胎架的模拟安装参数与实际的安装参数相同，然后按照安装参数进行设置拼接胎架，再利用拼接胎架进行实际安装多段钢梁，以使得大跨度的曲线型钢梁的预拱度和线性满足设计要求，从而减少调整过程。
