钢筋机械锚固板技术

　　Steel and mechanical anchorage plate technology

　　国家标准GB/T14370-2007

　　1.主要技术内容

　　钢筋锚固板又叫:精轧锚固板,热锻锚固板,45#锚固板,钢筋机械锚固板。

　　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。

　　1.Main technical content

　　Steel anchor plate is a basic technology of the concrete structure engineering, mechanical anchoring reinforcement for the reinforced concrete structure anchorage provides a kind of brand-new mechanical anchoring method, combined nuts and plate anchor plate through the straight thread connection with steel end to form reinforced mechanical anchorage device.

　　The mechanism of action is: the anchorage force of steel reinforcement is provided by the adhesion force between steel and concrete and the local bearing pressure of the anchorage plate.

　　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。

　　2. Technical indicators

　　Compared with traditional steel reinforcement and anchorage technology, it can be used to reduce the anchorage length of steel bars by 40% and more than 40%.

　　Application of steel anchor plate in the frame node, anchorage steel can be saved by more than 60%, anchor plate and steel bar end through the threaded connections, quick installation, quality and will easy to guarantee: anchor plate has big anchorage stiffness, anchorage performance is good, and the advantages of convenient construction, is advantageous to the commercialization of supply: the top several kinds of new type concrete frame node and the middle layer node structure form of reinforced mechanical anchoring, can greatly simplify the site construction of reinforced engineering, to avoid the reinforced dense congestion, tie difficult problem, and can improve the node force performance and improve the quality of concrete structures.

　　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。

　　3. Scope of application

　　The technology is suitable for hot rolled ribbed steel bar in concrete structure mechanical anchoring, main scope of application: used instead of traditional steel bar anchoring plate bending reinforcement, can be used to frame beam-column joints: instead of traditional bent bar and stirrup, used in the beam support: used for Bridges, hydraulic structure, such as subway, tunnel, nuclear power plants of reinforced concrete structure engineering anchorage;

　　Used as a fastener for steel bolts or rods.

　　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。

　　4. Typical projects that have been applied

　　Reinforced mechanical anchorage technology in nuclear power plant engineering, water conservancy and hydropower, building and other areas to more widely used, such as zhejiang sanmen AP1000 nuclear power plant, qinshan nuclear power phase ii expansion, Fang Gushan nuclear power station, etc.;

　　Shenzhen wanscience fifth garden project, huaii construction bureau complex building, etc.
