Multi-box-section multi-span continuous reinforced concrete superposed beam mounting method
The invention provides a multi-box-section multi-span continuous reinforced concrete superposed beam mounting method which comprises the following steps: S1, mounting a row of temporary brackets between adjacent cover beams, and mounting bracket jacks on the temporary brackets; s2, the precast beam sections are hoisted to the sliding device and the temporary support in a segmented mode, the precast beam sections are connected, and a first continuous beam piece is formed; s3, the support jack is released, the first continuous beam piece is supported by the sliding device, and the first continuous beam piece and the sliding device are temporarily and fixedly connected; s4, the first continuous beam piece is moved to the design position through a sliding device; s5, the steps S2-S4 are repeated, the second continuous beam piece is assembled and slides in place, temporary consolidation of the first continuous beam piece and the second continuous beam piece is relieved, and the first continuous beam piece and the second continuous beam piece are transversely connected into a continuous beam; and S6, the sliding device is controlled to jack the continuous beam, a permanent support is installed on the cover beam, the continuous beam falls onto the permanent support, and the concrete panel and the steel beam are overlapped. The number of supports can be reduced by adopting a beam splitting and assembling method.
本发明提供一种多箱截面多跨连续钢混叠合梁安装方法，包括：S1、在相邻盖梁之间安装一列临时支架，在临时支架上安装支架千斤顶；S2、分段吊装预制梁段至滑移装置和临时支架上，连接预制梁段，形成第一连续梁片；S3、释放支架千斤顶，由滑移装置支撑第一连续梁片，将第一连续梁片与滑移装置临时固结；S4、利用滑移装置将第一连续梁片移动至设计位置；S5、重复步骤S2～S4，拼装第二连续梁片并滑移到位，解除第一连续梁片和第二连续梁片的临时固结，将第一连续梁片和第二连续梁片横向连接为连续梁；S6、控制滑移装置顶升连续梁，在盖梁上安装永久支座，将连续梁下落至永久支座上，混凝土面板与钢梁叠合。本发明采用分束拼装的方法可节省支架用量。
