Zinc alloy single expansion anchors consist of two tubular shields and a cone nut pre-assembled into an integral unit, which are made of high-quality zinc alloy and manufactured by die-casting machinery. The tubular shield and conical nut are tightly bound together by spring band with spring clamping force. However, another type of zinc alloy concrete single expansion anchor cone nut is built into the lower end of two shields, which are tightly fastened with four clips on their edges, instead of the spring fastening.
护盾表面的下端被设计成螺旋形螺纹,是为了在产品被埋入预钻孔后,加强产品和孔壁之间的摩擦力,避免产品从孔中脱落,滑动或者拔出。锥形螺母上的整体凸耳可防止在膨胀过程中在管状护罩中转动。单膨胀锚栓由精密压铸锌合金制成,抗氧化,耐腐蚀和耐高低温,不生锈。它们通常用于单点锚固到轻至中等荷载强度的混凝土、砌块和砖块基层结构的锚固和固定物体。
The lower end of the shield surface is designed as a spiral thread to strengthen the friction between the product and the hole wall after the product is embedded in the pre drilled hole, so as to prevent the roduct from falling off, sliding or pulling out from the hole. The integral lug on the tapered nut prevents rotation in the tubular shield during expansion. The single expansion shield anchor is made of precision die-casting zinc alloy, which has anti-oxidation, corrosion resistance, high and low temperature resistance and no rust. They are usually used for anchoring and fixing the objects from single point anchoring in the concrete, masonry, block and brick base structures with light to medium load strength.
供应的产品内牙规格从1/4“到3/4”,钻孔径根据产品外径而定。安装时需要预钻一个安装导孔,夹紧安装物体后,在锚体内拧入一个机用螺栓,锥形螺母上移动,使2个护罩张开,从而产生膨胀力。
The size of the inner thread is from 1/4 "to 3/4", and the drilling diameter depends on the outer diameter of the product. During installation, it is necessary to drill a pilot hole for installation. After clamping the installation object, fasten a machine bolt into the anchor body, and move the conical nut to open the two shields to generate expansion force.
