  • Patent number: 7637071
    Abstract: An anchor having multiple legs for a concrete wall. The anchor has an interface plate with two sides. Disposed on a first side is a stud that is connectable to a bracket. Disposed on the second side of the interface plate are at least two legs. Each of the legs is insertable and secured to a respective hole formed in the concrete wall with epoxy. Once the epoxy cures, the leg attaches the anchor to the concrete wall.

  • Patent number: 7437829
    Abstract: A cross tie bracket that is attachable to a rod and a building structural element. The cross tie bracket has a generally cylindrical body sized to receive the rod and a gusset disposed between the body and a base. The base has a series of apertures formed therein for inserting fasteners through the base into the building structural element, temporarily securing the cross tie bracket to the building structural element with screws, and for providing alignment of a temporary drill guide with the base. A first and second end plate are disposed adjacent to each respective end of the cylindrical body. Each of the end plates has a rod aperture sized to receive the rod. Accordingly, by inserting and securing the rod to the end plates, it is possible to attach the rod to the building structural element.

  • Patent number: 6546678
    Abstract: A manually adjustable structural load transferring device and system for providing tension and compression force transfer between a plurality of spaced building structural members. A pair of load transfer members are each provided with a threaded first end and a second end, the threaded first end of one of the pair of members having threads of opposite pitch to those of the first end of the other one. A coupler member has first and second threaded ends engaged with the threaded first ends of the pair of load transfer members so that the length of the assembly can be adjusted by relative rotation between the coupler member and the load transfer members. An end connection device is attached to the second end of each of the load transfer members, the end connection device including a plurality of fastener apertures and a plurality of bolt apertures for securing the base plate to a building structural member.

  • Patent number: 6425220
    Abstract: A continuity tie for providing both tension and compression resistance to externally induced movement of building structural members. A central body member is provided with a plurality of bolt mounting apertures in a staggered pattern and a pair of end plates having a rod aperture. One embodiment employs a tubular central body member having a hollow interior; another embodiment employs a generally U-shaped central portion with flanking flanges. Both embodiments can be mounted to building structural members separated by an intervening building structural member, with the continuity ties being secured together by means of a single rod arranged in the rod apertures in each continuity tie and secured in place by means of nuts. The staggered bolt patterns reduce the probability of mounting all bolts in a defect region of a timber building element. The hollow tube embodiment is symmetric and cannot be installed backwards. The rod aperture may be centered or offset from the central axis of the continuity tie.
