Possible combinations
Products of HRC 700 Series can be combined with other HRC-products (T-heads or rebar couplers) and can be delivered with threaded rods, nuts and washers.
Example of use of HRC 720 Series
- Foundation coupler is installed even with the surface of the foundation and cast in. The opening in the sleeve is closed with a plastic cap to prevent cement lime or dirt from entering into the sleeve. There are no protruding part witch can be damaged or could present a danger.
- The treaded part is screwed into the sleeve. Under combined tension- and shear load the high-strength material of the bolt will guarantee the necessary capacity. Maximum allowable tension load is limited by the capacity of the bolt (up to strength 8.8), but shear load is restricted by the concrete pressure against the sleeve.
- The outer diameter of the sleeve gives the bolt better transversal contact against the concrete and therefore a higher shear capacity compared to cast in threaded rods. Higher capacity in the threaded part can therefore be used to transmit big shear forces from a footing and down into the concrete.
- Screwed in threaded parts make it possible to change damaged parts in an easy way and at the same time to keep a sound foundation.
