Foundation Brackets

Each of the piering products is used in conjunction with an array of foundation brackets designed to transfer the bearing weight of the foundation to the pier, for a specific situation. All brackets are furnished with POLYARMOR G17 polyethylene copolymer thermoplastic powder coating for corrosion protection.

Commercial Bracket

The Ram Jack® Commercial Bracket Assembly is the most common bracket used with 2-7/8" helical screw anchors and steel piers. It consists of a foundation bracket that fits underneath the building foundation, a support strap that connects the pier to the bracket, and a guide sleeve that encompasses the pier shaft where it telescopes through the bracket. Mounting holes are provided so that the bracket may be permanently secured to the foundation. It carries a maximum allowable load of 36,000 pounds.

The prime functions of the commercial bracket are:

• To provide a means for attaching the pier to the building foundation
• To provide a connection between the building foundation and the hydraulic rams used to install steel piers and to lift the structure
• To transfer the weight of the structure onto the pier column
• To provide a user-friendly means of lifting selectively and securing the building foundation at the desired elevation

Applications

The Ram Jack® Commercial Bracket Assembly is used to provide support for existing foundations that have experienced, or are in danger of experiencing, distress due to settlement. The bracket is used for residential and light commercial building foundations where the bracket may be set at a lower corner of the footing with its bearing plate under the footing. Because it places the pier in an eccentric position away from the center of the footing, it is recommended this bracket be used with 2-7/8" shaft helical screw anchors and steel piers only.

Advantages

The Ram Jack® Commercial Bracket Assembly may be used with either helical screw anchors or steel piers. The bracket's guide sleeve is available in variable length to accommodate differing soil profiles. All bracket components are polyethylene copolymer thermoplastic powder coated for corrosion resistance.

Porch Bracket

The Ram Jack® Porch Bracket Assembly, is a light-duty version of the standard Commercial Bracket. It is used with 2-3/8" helical screw anchors. It carries a maximum allowable load of 25,000 pounds.

Pre-construction Bracket

Ram The Ram Jack® pre-construction bracket Assembly consists of 1/2" thick steel plate welded to a 3-1/2" OD x 1/4" wall steel tube. It is typically used with 2-7/8" helical screw anchors that are installed prior to construction of a new foundation. The bracket may be tied to rebar in the foundation before concrete is poured. It carries a maximum allowable load of 25,000 pounds.

Slab Bracket

The Ram Jack® Slab Bracket consists of two 17" long steel channels spaced 2" apart, with four 3/16" x 4" x 4" steel plates welded on top and bottom on each end. The lifting tube is 2-7/8" OD x 1/4" wall x 12" long steel, with a 1/4" x 3" x 3" plate having a 1-1/4" diameter hole in its center welded to one end. A 1-1/4" nut is welded over the hole in the end plate. A bearing plug for the upper end of the pier is also provided. It is designed to be used on 2-3/8" piers and carries a maximum allowable load of 25,000 pounds.

Applications

The Ram Jack® Slab Bracket Assembly is used to underpin and raise slabs. Installation requires coring a hole in the slab, through which the pier is installed. The bracket components are then dropped end-wise through the hole and assembled as shown. The slab can then be supported in place or raised by tightening the lock-off bolt.

Wall-mounted Bracket

The Ram Jack® Wall-mounted Bracket Assembly, has all of the advantages of the Commercial Bracket and is useful for many special applications. It is attached to a foundation or footing wall with heavy-duty hardware. It is used with 2-7/8" helical screw anchors. It carries a maximum allowable load of 25,000 pounds.
