Abstract
A flat plate is used to cover a mounting hole in a masonry wall face and is held in place by a set of wire hooks. The hooks are able to slide into holes in the plate and catch onto the interior surface of the wall in order to hold a clearance hole in the plate concentrically with respect to the mounting hole. An anchor bolt is supported at the center of the mounting hole by the clearance hole in the plate while grout is poured into the masonry blocks thereby assuring that the bolt is positioned properly in accordance with building code.
Claims2
A masonry wall structure for mounting a wall plate, the structure comprising:
- a hollow masonry wall providing a front surface and, spaced apart therefrom, a rear surface, the masonry wall further providing a bolt mounting hole therein, the bolt mounting hole providing a bolt mounting hole diameter;
- an anchor bolt positioned centrally within the mounting hole and extending outwardly therefrom;
- a flat plate of a stiff sheet material, the flat plate laying in contact with the front surface of the wall, the plate having a clearance hole therein, and a plurality of hook mounting holes arranged on a diameter concentric with the clearance hole, the diameter being approximately equal to the bolt mounting hole diameter;
- a plurality of wire hooks, each of the wire hooks having a first leg, and a second contiguous leg positioned generally at a right angle to the first leg, the first leg of each of the wire hooks being frictionally engaged in one of the hook mounting holes and extending through the bolt mounting hole into the masonry wall so that, together, the first legs of the wire hooks position the flat plate on the front surface such that the clearance hole in the flat plate is concentric with the mounting hole;
- the second leg of each of the hooks laying in contact with the rear surface of the wall so that the flat plate is held tightly against the front surface thereof with the anchor bolt centered within the bolt mounting hole;
- a grout filling the hollow masonry wall and laying in contact with the flat plate and further, between the anchor bolt and the bolt mounting hole.
