在高层建筑混凝土施工过程中,将模板及支撑架体在后浇带处断开,有效截断混凝土泵送时产生脉冲振动引起的模板和模架的振动,减少对已经初凝的混凝土水泥石结构的破坏.后浇带处采用“多种模板主梁早拆模板支撑头”,减少拆模时的二次支顶.在后浇带处不铺设下部模板,便于后浇带两侧混凝土凿毛和清理.后浇带封闭安装模板,操作简易、适用性强,易于推广.%In high-rise building construction process of concrete,the template and the supporting frame is disconnected in the post pouring strip,effectively cut the vibration of the template and frame,when concrete pump generate pulse vibration,and reducing damage to the structure of early concrete cement.Adopts the" multiple template early-dismantling template support girder head " in the late poured band,reduce the stripping of two top teams.Not laying bottom template on the after-pouring,chiseling and cleaning is convenient.During the installation templates of after-pouring,the invention has simple operation,strong applicability,easy extension characteristics.
