Floor-to-Wall versions of Twinsert can be configured in accordance with the floor-to-wall options available with the standard joint system selected as the flanking system–consult the product page for the specific system.
As with loading capacity and floor-to-wall options, leg heights are driven from those available in the standard joint system selected as the flanking system.
This option also allows for using DIFFERENT leg heights on either side of the bridging element. You might choose this option if there is a floor height differential across the joint.
FS 110 Twinsert with Aluminum Traffic Plate
In this example, twin FS 110/45, heavy-duty, aircraft-aluminum joints have been connected with a 1/2″ (12mm) aluminum bridging plate.
The width of the plate has been custom made to allow the bridging of an 8-inch wide expansion joint gap.
The thickness of the plate was calculated to handle forklift and vehicle loads required by the client–the Washington DC Convention Center (click herefor a project profile and to see the installed Twinsert).
In this particular application, the Twinsert was installed into a recess (blockout) on each side of the joint gap and installed proud of the surrounding concrete by the thickness of the adjacent carpet. As a result, the Twinsert system sits flush with the finished walking and traffic surface.
FP 70/30 Twinsert with Recessed Plate for Tile
In this example, twin FP 70/30, medium-duty, aluminum/elastomeric insert joints have been connected with a 1/4″ (6mm) aluminum bridging plate that is recessed from the finished surface of the joint to receive field-installed tile to match the floor.
The joint gap in this application is only 3-inches but movement due to uncontrolled airspace below the lobby floor results in movement in excess of that which could be handled in numerous previous attempts using other manufacturers standard floor products for 3-inch joints.
By using twin FP 70’s the movement capability is doubled. By spacing them out so that tile can be installed between them allowed coordination with black accent tiling patterns.
