Spike® Vibration Resistant Anchor from The WDS Group
SPIKE®
The Powers SPIKE is a patented, one-piece, vibration resistant anchor for use
in concrete, block, brick, or stone. Several head styles and anchor materials are
available.
Using a special manufacturing process, the SPIKE anchor is formed with an "s"
shaped configuration at the working end of the anchor to create an expansion
mechanism. The pre-expanded mechanism is activated as the anchor is driven into
the drilled hole and creates a spring type compression force against the walls of
the hole. To develop the spring action of the expansion mechanism, manufacturing
processes such as heat treatment and cold working are used.
The basic working principle is the same for all versions. As the anchor is driven
into the hole, the expansion mechanism is compressed and flexes to accommodate
the size of the hole. Once seated at the required embedment, residual spring
force developed in the expansion mechanism provides three compression forces
at three different levels, at the bottom of the anchor hole. When a vibratory load
is applied to some anchors, the area of the base material around the expansion
mechanism may experience localized pulverization at the point of contact. The
Powers SPIKE has been designed to overcome this problem. When subjected to
vibratory loads, the SPIKE will expand due to the residual spring action of the
expansion mechanism if localized pulverization occurs.
Use of the SPIKE anchor reduces installation time. Since the anchor is pre-expanded,
there is no secondary tightening operation required which greatly reduces the
overall cost of an anchor installation. The simple installation procedure helps to
insure a quality application each time the SPIKE anchor is used.
