Zinc alloy double expansion anchor is a kind of anchorage for masonry, concrete or lightweight solid wall base structure for anchoring and fixing the objects. It is made of zamac material by die casting machine. The design has two heavy shields and two conical expansion nuts pre-assembled by a spring ring.One nut is tapped by american standard inch internal thread, and the other nut has no thread.
安装使用时,需要预钻一个安排孔洞,用机械螺栓拧入锥形膨胀螺母中,扩张锌合金护盾实现膨胀功能和物体的安装固定目的。根据锥螺母内螺纹和锚体直径钻孔。在整个砌体锚碇领域中,大多是在靠近锚底的孔内扩张,以防止锚杆松动。
When installing and using, it is necessary to drill an installing hole, screw the mechanical bolt into the conical expansion nut, and expand the zinc alloy shield to realize the expansion function and the installation and fixation of the objects.To drill a hole, according to the cone nut internal thread and anchor body diameter. In the whole field of zamac masonry anchor, the most of them expand in the hole near the anchor bottom to prevent the bolt from loosening.
双膨胀锚杆的应用特点不同于其他砌体锚杆产品。而不是锚底部的强烈膨胀造成一个沉重的抓地力,整个锚扩展,但只是轻微的,以分配压力整个表面的锚体。
The application characteristics of double expansion bolts are different from other masonry anchors products. Instead of the strong expansion at the bottom of the anchor causing a heavy grip, the entire anchor expands, but only slightly, to distribute pressure across the surface of the anchor body.
双膨胀锚是一种砌体锚,比较适合用于锚固强度或基层结构有质量有问题的材料。在墙体固定锚的体系中,大多数依靠变形靠近锚底部的一部分,一旦进入孔内,以防止锚松动。
Being suitable for the quality of masonry structure. In the wall fixed anchor system, most rely on the deformation of the part near the bottom of the anchor, once it enters the hole, it can prevent the anchor from loosening. Double expansion anchors are different from other masonry anchors. The bottom of the entire anchor does not expand sharply to produce strong grip, but expands slightly in size to distribute pressure over the entire surface area of the anchor.
双锚在质量可疑的基材(即软质或砂质)中工作良好,因为它在整个长度上扩展。这为确保了充分的摩擦力提供了最大的可能,从而增加了获得最小保持力的性能。
The double expansion shield anchor works well in a base material of dubious quality (i.e., soft or loose) as it extends over the entire length. This provides the maximum possibility of ensuring sufficient friction, thereby increasing the ability to obtain the minimum retention force.
