In the expansion anchor bolt system, zinc alloy expansion anchor is designed and used to fix and install the fixtures or structure in the base structure such as concrete or masonry. Zinc hammer drive anchor is one of the many zinc alloy expansion anchors, which is pre assembled by zinc alloy expansion body and iron nail. The lower end of the expansion body is designed as a straight fork, without internal and external threads, and without other accessories.
The head is shaped like a mushroom head with a circular inner hole. An iron nail is pre installed. In actual use, the head of the iron nail is directly hit by a hammer until the head of the iron nail is flush with the mushroom head of the expansion body. With the nail nailing into the expansion hole, the lower end is fully split to produce expansion function to bear the external load. The design is ingenious, the installation is fast and convenient, and it is suitable for various materials, It includes concrete, solid block, brick wall or brick wall.
It is widely used in various places and engineering projects. When used with structural steel members, they can also be used to firmly adhere the embedded plate to the concrete foundation, suitable for fixed installation with medium and high strength.
锌合金锤钉锚广泛采用蘑菇头型号,公制和英制规格尺寸齐全,材料采用高等级的锌合金材料,无铅,汞等有害成分。膨胀体可以镀锌处理,如有特殊场所的特殊需要可以提供不锈钢钉子加强防锈和防腐性能。
Mushroom head type is widely used in zinc alloy hammer drive anchor. The Metric and Inch specifications are completed. High grade zinc alloy material is used as the material, which is free of harmful ingredients such as lead and mercury. The expansion body can be galvanized, and stainless steel nails can be provided to strengthen the anti rust and anti-corrosion performance if there are special needs in special places.
* 根据膨胀体外径,用冲击钻打一个安装导孔。
* According to the outer diameter of the expansion body, drill an installation guide hole with an impact drill and to remove dust and waste residue.
* 插入锌合金锤钉锚夹紧固定物体。
* Insert the zinc alloy hammer anchor to clamp the fixed object.
* 直接用铁锤击打铁钉头部。
* Hit the nail head directly with a hammer.
* 连续击打一直到铁钉头部和蘑菇头齐平,则产生膨胀性能,完成安装操作。
* If the head of the steel nail is even with the mushroom head, the expansion performance will be produced and the installation operation will be completed.
