过去进行框架结构柱滑模施工时,常因液压系统故障、滑模装置结构变形、混凝土浇灌速度和大气温度等因素的影响,致使滑露出来的混凝土表面不够光滑,甚至有拉裂和严重掉角现象。针对这些缺点,首钢第二建筑工程公司第一工程队在焦化1号转运站工程上大胆革新,采用了“滑框倒模”新工艺。具体作法是:将原来的柱模板改为固定在围圈上的角模和设在角模里侧的柱面活模板,柱面活模板是由三至四块小模用螺栓联结组成。滑升时,角模提升,活模不动,每
In the past, during the construction of column-sliding construction of frame structures, the surface of the exposed concrete was not smooth enough, and even cracked and severely lost due to the effects of hydraulic system failure, structural deformation of the sliding mold device, concrete pouring speed, and atmospheric temperature. Angle phenomenon. In response to these shortcomings, the first engineering team of Shougang No.2 Construction Engineering Co., Ltd. boldly innovated in the construction of the Jiaozuo No. 1 transfer station, and adopted a new process of “sliding frame molding”. The specific method is: to replace the original column template fixed in the corner of the corner die and the corner die on the side of the cylindrical live template, cylindrical live template is composed of three to four small bolts connected with the composition. When sliding, the corner die is raised and the live die does not move.
