The utility model belongs to the technical field of movable formwork construction of continuous rigid frame bridge in bridge engineering, in particular to a construction device of movable formwork beam anti-staggering platform for continuous rigid frame bridge, which includes several anti-staggering platform crossbeams and movable formwork frames. The anti-staggering platform crossbeams are near the splicing section of the formed box girder and are arranged on the top surface of the formed box girder along the direction of the cross section, and all anti-staggering platform crossbeams are installed on the same surface. On the straight line of cross section, there are some vertical pair-pulling holes in the formed box girder, and the cross beam of the anti-stagger platform is fixed by the thread steel and the movable die holder. The thread steel penetrates into the pair-pulling holes installed in the formed box girder, and the ends are locked by nuts. There are fewer than two threaded steel parts in the connection between each cross beam of the anti-stagger platform and the movable die holder. The utility model solves the problem of staggered platform in the construction section of the movable formwork girder by installing the anti-staggering platform tie rod (thread steel) to connect the completed and non-poured section box girder as the carrier.

一种连续刚构桥移动模架制梁防错台的施工装置
本技术属于桥梁工程连续刚构桥移动模架施工的
,具体涉及一种连续刚构桥移动模架制梁防错台的施工装置。
技术介绍
城市轨道交通基建工程迅速发展,城市桥梁结构多、连续刚构桥广泛采用移动模架施工。目前下行式移动模架施工中均为主梁受力,由于主梁为弹性结构,施工中各断面均设置预拱度,在施工节段处施工段受荷载后主梁发生弹性变形导致梁体底部形成错台的缺点。影响了连续刚构桥的施工质量和外观质量。
技术实现思路
本技术为了解决城市桥梁移动模架制梁在各施工节段错台的问题,进而提供了一种连续刚构桥移动模架制梁防错台的施工装置。本技术采用如下技术方案:一种连续刚构桥移动模架制梁防错台的施工装置,包括若干防错台横梁和移动模架,防错台横梁靠近成型箱梁的拼接断面并沿横断面方向间隔设置于成型箱梁顶面上,所有防错台横梁安装于同一横断面直线上,成型箱梁内预留有若干竖向对拉孔洞,防错台横梁通过螺纹钢与移动模架固定连接,螺纹钢穿入安装于成型箱梁的对拉孔洞内、两端通过螺母锁紧;每根防错台横梁与移动模架的连接螺纹钢部少于两根。所述对拉孔洞内距离成型箱梁的拼接断面不少于30cm。所述防错台横梁至少设有三组,成型箱梁的左右两端对称分别设有一组且防错台横梁的外侧端头与成型箱梁的顶板侧端面平齐,其余防错台横梁均布间隔设于中间。本技术是通过移动模架为载体,通过安装防错台拉杆(螺纹钢)连接已完成和未浇筑段箱梁的方式来解决移动模架制梁在施工节段会产生错台的问题。有效解决了移动模架制梁在施工节段会产生错台的问题,避免了梁体的错台处理,节省施工费用,有效的保障了连续刚构桥的 ...
