钢筋混凝土剪力墙、柱和梁施工中,常常需用拉片加固钢模板,拉片与钢模板之间通过卡环连接。拉片的规格、布置一般经过计算,但是现场操作时经常出现拉片少卡、漏卡现象,容易造成混凝土胀模、跑模现象,而拉片两端的钢片被压在模板边肋间,这样就很难检查钢片被卡环卡住与否。因而,施工过程中检查拉片的固定是一项关键而繁琐的工作。在工程实践中,我们采用加长钢片的方法对拉片进行了改进。即把钢片在
Reinforced concrete shear walls, columns and beams in the construction, often need to strengthen the steel plate with a pull tab, pull the tab and the steel template connected by a snap ring. The specification and layout of the pull-tab are usually calculated, but the pull-tab-less card and slip-off phenomenon often appear on the spot, which can easily lead to the bulging and running of the concrete. The steel sheets at both ends of the pull-tab are pressed against the edge of the template, This makes it difficult to check whether the steel is stuck in the snap ring or not. Therefore, the inspection process during the fixed pull tab is a key and cumbersome work. In engineering practice, we use the method of lengthening the steel sheet to improve the pull-tab. That is steel in
