Abstract

A retrofit foundation system for bolting a sill plate to a foundation including, an upper piece member having a first upper portion for lying against the sill plate for bolting to the side of the sill plate and having a second portion extending outwardly from the side of the sill plate along the top of the foundation and extending past a side wall of the foundation. A lower piece member has a first lower portion for lying against the side of the foundation for bolting to the side of the foundation and has a second portion extending outwardly from the side of the foundation at the top of the foundation and with the outwardly extending portions of the upper piece member and the lower piece member lying adjacent to each other along a plane substantially parallel to the top of the foundation. The outwardly extending portions of the upper and lower piece members are attached together to transfer any external forces from the sill plate to the foundation.

Claims14

Dependent claims

A two-piece retrofit foundation device for bolting an existing wood sill plate of a building structure having top, bottom and side walls to an existing foundation of the building structure having top, bottom and side walls to resist seismic or lateral forces and with the bottom wall of the sill plate lying on the top wall of the foundation to form a common plane including,

an upper piece member having a first upper portion for lying against a side wall of the sill plate for bolting to the side wall of the sill plate and having a second upper portion to form an outwardly extending portion which extends out from the side wall of the sill plate and lies along the common plane at top wall of the foundation to extend past a side wall of the foundation,
a lower piece member having a first lower portion for lying against the side wall of the foundation for bolting to the side wall of the foundation and having a second lower portion to form an outwardly extending portion which extends out from the side wall of the foundation and which lies in the common plane at the top wall of the foundation and with the outwardly extending portions of the upper piece member and the lower piece member lying adjacent to each other along the common plane at the top wall of the foundation;
and
means for attaching together the outwardly extending portions of the upper and lower piece members so as to transfer any seismic or lateral forces from the sill plate to the foundation.

A method of retrofitting the bolting of an existing wood sill plate of a building structure having top, bottom and side walls to an existing foundation of the building structure having top, bottom and side walls to resist seismic or lateral forces and with the bottom wall of the sill plate lying on the top wall of the foundation to form a common plane and including the following steps,

providing an upper piece member having a first upper portion lying against a side wall of the sill plate and having a second upper portion to form an outwardly extending portion which extends out from the first upper portion and lies in the common plane along the top wall of the foundation and extends past the side wall of the foundation,
providing a lower piece member having a first lower portion lying against the side wall of the foundation and having a second lower portion to form an outwardly extending portion which extends out from the first lower portion and lies in the common plane and having the outwardly extending portions of the upper piece member and the lower piece member lying adjacent to each other along the common plane at the top wall of the foundation;
bolting the appropriate portion of one of the upper or lower piece member to the side wall of the sill plate or foundation,
bolting the appropriate portion of the other of the upper or lower piece member to the side wall of the sill plate or foundation, and
attaching together the outwardly extending portions of the upper and lower piece members so as to transfer any external seismic or lateral forces from the sill plate to the foundation.
