R1H & R7S Spin-Lock Concrete Anchors

Through years of development, Williams has produced and patented the Prestressable, Hollow-Core, Groutable Spin-Lock Concrete Anchoring Systems. The hollow-core allows the anchor to always be grouted from the lowest gravitational point. In an up-bolt-ing situation, the grout is pumped in through the plastic grout tube and begins to fill the drill hole from the plate. The grout rises until the entire hole is filled and the grout returns through the hollow bar. In down grouting situations, the grout is pumped through the hollow bar and starts at the bottom of the hole. Grout rises and returns through the de-airtube when the hole is filled. Improperly or incomplete grouted anchors are subjected to relaxation and corrosion. Because the Spin-Lock head assembly provides 300º perimeter expansion anchorage and develops the full strength of the rod, the hollow-core concrete anchor may be prestressed to the desired load and tested prior to grouting

(*) Do not exceed these numbers
(1) Max factored design load is based on steel strength and shall not exceed yield strength.***Note – ACI 318 limits the nominal strength of the anchor rod to 1.9*fy or 125 KSI, whichever is less***
(2) Care should be taken to drill a straight and properly sized hole.
(3) More torque may be required on long anchors or if the head assembly is next to rebar. Consult your Williams Representative for more specific details.
(4) All above torque values are for greased (MolyKote GN) threads.
(5) Stress to desired tensile load using a hollow ram hydraulic jack. Consult your Williams Representative.
(6) Full ultimate strength of anchor can be achieved at listed embedment depth, provided there are no edge or spacing effects on the anchor.
(7) WILLIAMS reserves the right to ship full length or coupled units as necessary.

 

Head Assemblies

The Williams Spin-Lock anchor assembly gives full 300-degree bearing area. The smooth shell design allows for maximum shell to rock contact and eliminates “point of contact” created by serrated designs. The cone design supports the shell 300°, thereby eliminating any possible collapse of the shell under high load conditions. The thrust ring stop in front of the shell prevents any possible rebound of the expanded shell down the cone when subjected to nearby blasting. The Williams Spin-Lock anchor has been field-proven on the world’s largest projects to far exceed in tension capacity any other mechanical anchor on the market.

Coupled Head Assemblies

Williams can manufacture Spin-Lock Anchor systems with the use of a transition coupling, which allows the anchor to be designed with a continuously workable thread-form. This is advantageous when the anchor length may need to be adjusted in the field due to variable site conditions. The transition coupling engages a continuously threaded U.N. bar into the head assembly and the All-Thread Bar (typically Grade 75 All-Thread Rebar or 150 KSI All-Thread-Bar) is attached to the other end of the coupling.
