　　钢筋机械锚固板技术

　　1、主要技术内容

　　钢筋的锚固板是混凝土结构工程中的一项基本技术,钢筋机械锚固技术为混凝土结构中的钢筋锚固提供了一种全新的机械锚固方法,将螺帽与垫板合二为一的锚固板通过直螺纹连接方式与钢筋端部相连形成钢筋机械锚固装置。其作用机理为:钢筋的锚固力由钢筋与混凝土之间的粘结力和锚固板的局部承压力共同承提或全部由锚固板承担。

　　2、技术指标

　　该指术相比传统的钢筋机械锚固技术,在混凝土结构中应用钢筋锚固板,可减少钢筋锚固长度40%又上,节约锚固钢筋40%以上;在框架节点中应用钢筋锚固板,可节约锚固用钢材60%以上,锚固板与钢筋端部通过螺纹连接,安装快捷,质量及必能易于保证:锚固板具有锚固刚度大,锚固性能好、方便施工等优点,有利于商品化供应:几种新型的混凝土框架顶层端节点与中间层端节点钢筋机械锚固的构造形式,可大大简化钢筋工程的现场施工,避免了钢筋密集拥堵,绑扎困难的问题,并可改善节点受力性能和提高混凝土建筑质量。

　　3、适用范围

　　该技术适用于混凝土结构中热轧带肋钢筋的机械锚固,主要适用范围有:用钢筋锚固板代替传统弯筋,可用于框架结构梁柱节点:代替传统弯筋和箍筋,用于支梁支座:用于桥梁、水工结构、地铁、隧道、核电站等混凝土结构工程的钢筋锚固;用作钢筋锚杆(或拉杆)的紧固件等。

　　4、已应用的典型工程

　　钢筋机械锚固技术在核电站工程、水利水电、房屋建筑等领域得于较为广泛地应用:如浙江三门AP1000核电站、秦山核电二期扩建、方家山核电站等;深圳万科第五园工程、怀来建设局综合楼等。

　　钢筋与混凝土之间的粘结不锚固性能是混凝土结构研究的基本问题之一,它对结构中钢筋强度的发挥、裂缝控制、配筋构造以及结构的安全性均有重要影响。目前,在钢筋混凝土结构中,工程中钢筋常用的机械锚固方式是使用末端带弯钩的构造,90°戒135°弯钩钢筋虽然在一定程度上增强了钢筋锚固性能、减小了锚固长度,但是弯折戒较大的弯弧半径构造要求经常带来许多问题,如造成梁-柱节点区钢筋拥挤、弯折戒弯钩不其他钢筋的布置互相干扰、构件尺寸丌能满足锚固长度要求等等。在使用大直径钢筋时,这些矛盾更加突出。

　　CABR钢筋机械锚固技术,徆好地解决了这一难题,在保证钢筋机械锚固性能的基础上,优化钢筋锚固条件,减少钢筋锚固长度,节约锚固用钢杅,斱便斲工,提高混凝土浇筑质量。
