The grout process was then repeated on top to complete the composite action of the Helibeam System. When each length of HeliBar came to its end, the next length was overlapped by 1.5 feet to create one monolithic run around the building, with corners kinked in at a 90-degree bend. The recessed Helibeam was then pointed over the top, rendering it virtually transparent to the naked eye upon completion.
Additionally, DryFix remedial ties were used in tandem with the Helibeam System for lateral restraint in the facade. The DryFix ties were installed simply by being power-driven into position, via a small pilot hole, using a special installation tool that leaves the end of the tie recessed below the outer face. This allowed an "invisible" finish. Crack stitching was also conducted to secure local cracking and stabilize any further movement of separating brick areas.
"The Helibeam installation was easy as it's a lot like crack stitching but in a longer run," says SPS Project Engineer and Manager Alan Fleischer. "After we completed the installation, you'd never know what was done to the building."
Product Watch
Bosch Precision Stop Bits are designed to bring precision, speed and professionalism to a task once marked by guess work and drill bits marked with tape. They are used in key masonry applications ranging from suspension of struts for electrical and air systems to hardware for overhead piping and sprinkler systems. Applications are designed to incorporate drop-in anchors.
A steel collar on each bit marks the precise depth of the hole. Once the collar is flush with the concrete surface, the correct depth is reached.
Bosch offers a complete line of five carbide-tipped steel bits that include 3/8, 1/2-and 5/8-inch sizes. Depths range from 13/16-to 2 1/16-inch. The size and depth range of the products accommodates more than 80 percent of all requirements for drop-in anchors. The size and depth combinations prevent over-drilling and drilling into rebar, which allows the professional user to install drop-in anchors properly and securely. The bits take the place of the manual depth gauge on rotary hammers, a feature many users disable. Drill bit maximum speed is 1,100 rpm. IMAS
