Abstract
An earthquake anchor for a mass plywood panel has a replaceable fuse plate clamped between two members embedded into the mass plywood panel and anchored to the floor or foundation. The fuse plate deforms in an earthquake but keeps the mass plywood panel intact. The deformed fuse plate is then replaced with a new fuse plate.
Claims2
An earthquake anchor for a mass plywood panel comprising:
- a top C-shaped member comprising downward arms terminating in downward facing flanges;
- a bottom C-shaped member comprising a base and upward arms terminating in upward facing flanges;
- at least one fuse plate clamped between the downward facing flanges and the upward facing flanges,
- the at least one fuse plate disposed substantially parallel to a floor, such that the top C-shaped member, the bottom C-shaped member and the at least one fuse plate form a substantially rectangular frame;
- a threaded bolt comprising a proximate end and a distal end, the distal end affixed to the floor by way of attachment means, the threaded bolt disposed substantially perpendicularly to the floor;
- wherein the substantially rectangular frame configured to be mounted in a rectangular opening formed in the mass plywood panel, the substantially rectangular frame adapted to snugly fit therein;
- wherein the threaded bolt configured to be inserted in a vertical bore formed in the mass plywood panel, the vertical bore communicating with the rectangular opening;
- wherein the at least one fuse plate comprising a first opening disposed substantially in the middle of the at least one fuse plate;
- wherein the base comprising a second opening, such that the first opening, the second opening and the vertical bore are aligned, the first opening and the second opening receiving the proximal end;
- wherein a pair of nuts threaded on the threaded bolt and disposed on either side of the at least one fuse plate abutting the at least one fuse plate.
