Construction method for reinforcing and repairing concrete cover beam through sticky steel
The invention relates to a construction method for reinforcing and repairing a concrete cover beam through sticky steel. The construction method comprises the steps of installation of a hanging type construction platform, crack grouting of the cover beam, installation of a cover beam reinforcing steel plate, treatment of the broken end of the cover beam and reinforcement of a pier column. The construction method has the beneficial effects that the temporary auxiliary stable hanging bracket and the hanging type construction platform are adopted for pasting the steel plate strips, the auxiliary stable hanging bracket supports the bent cap reinforcing steel plate through the steel plate reserved connecting rod, the hanging type construction platform is fixed to the pier column through the platform hoop, and the construction quality of steel plate pasting is improved; the integral construction effect of reinforcing the bent cap is further improved; an auxiliary hole is formed in the precise lofting and guiding auxiliary device, and the anchor bolt hole is mounted by adopting the auxiliary hole in the precise lofting and guiding auxiliary device, so that the mounting precision of the anchor bolt is improved; and the broken part of the capping beam adopts a splicing and steel bonding reinforcing technology, and fiber concrete is poured through a capping beam splicing template, so that the integrity of capping beam reinforcement is improved.
本发明涉及一种粘钢加固修复混凝土盖梁的施工方法，包括步骤：吊挂式施工平台安装、盖梁裂缝灌浆、盖梁加固钢板安装、盖梁破碎端处理、墩柱加固。本发明的有益效果是：钢板条粘贴采用临时辅助稳固吊架及吊挂式施工平台，辅助稳固吊架通过钢板预留连接杆支撑盖梁加固钢板，吊挂式施工平台通过平台抱箍与墩柱固定，提高了钢板粘贴的施工质量，进而提高了盖梁加固的整体施工效果；精确放样与导向辅助装置上设有辅助孔，锚栓孔采用精确放样与导向辅助装置上的辅助孔进行安装，提高了锚栓的安装精度；盖梁破碎处采用拼接粘钢加固技术，通过盖梁拼接模板浇筑有纤维混凝土，提高了盖梁加固的整体性。
