Quad-Lock Metal Brackets

Quad-Lock's unique metal brackets make the assembly of many ICF wall elements simple, quick, and secure. Metal brackets interlock with panels and ties to provide critical support against concrete pressure while requiring no external bracing. 

This also means that in most cases, crews can work safely from the inside of the building (from successive floor levels) with no ladders or scaffolding necessary on the outside of the building.

Quad-Lock corner brackets allow for the quick and secure assembly of 90 degree corners and eliminate the need for any external corner bracing. 

They come in two configurations: the Inside Corner Bracket and the Outside Corner Bracket.

Corner brackets are made of flat galvanized steel and are designed to fit over Quad-Lock panels placed at 90° to one another. 

The brackets have holes that match the panels' foam interlock knobs, and slots that allow the ties and tie flanges to be inserted once the bracket has been placed over the panels.

When installed properly, the corner brackets combined with the ties and tie flanges alone will absorb the forces of the poured concrete at the recommended slump and pour rates, eliminating the need for structural corner bracing. 

Bracing may be needed only to assure plumb and alignment in relation to the rest of the wall.

Corner and angle brackets are recessed from the surface of the EPS panels to minimize thermal bridging and avoid flashing through stucco.

Quad-Lock hinged angle brackets allow wall angles of almost any degree to be easily formed and braced. Once the panel ends are mitered at the bi-section degree of the desired angle (and through the center of a knob), the bracket folds out to match the angle of the wall.

Similar to the 90° corner bracket, ties and tie-flanges are placed through the angle bracket and into the panel. Angle brackets are only needed on the outside of the angle and will ensure that the wall is held together plumb and true without the need for extra bracing.

34" long Straight Brackets secure 90° Corners for thicker walls and 4-way wall intersections

Since the regular Outside Corner Brackets may not be long enough for thicker walls (requiring Red Ties or longer), Straight Brackets can be cut in half and overlapped with the Outside Corner Brackets to extend them. Ensure to add tie-flanges into the overlaps which should be a minimum 3 slots.

Straight Brackets can also secure 4-way wall intersection by placing pairs of Straight Brackets that span across intersecting walls. This provides a solid connection between two wall segments that have been interrupted by another wall. For example, the diagram shows an exterior wall that passes between an interior wall and an exterior buttress wall. 

The buttress wall can now be secured back to a longer wall section, and will not have to be braced from outside the building line. In the case of multi-story construction, the higher the building, the safer and more economical this becomes, as crews can work from the safety of the inside of the building.

Endcap Brackets help to form insulated wall end caps. With scrap foam pieces, the Endcap Bracket replaces lumber or plywood forms and leaves no exposed concrete. 

The Endcap Bracket is similar to an outside corner bracket and can be used for insulated wall ends ranging from 6" to 12" [150mm to 300mm] nominal cavity size.
