Abstract
This invention provides for reinforced wood structures including framing members and a method to reinforce the connection between structural members to increase the load bearing capacity of framing member intersections by covering the intersecting wood framing members with a layer of a liquid elastomer including polyurea.
Claims14
A wood framing structure comprising:
- a first wood structural member having a first surface;
- a second wood structural member having a second surface;
- a connection by a connection means between a portion of the first wood structural member and a portion of the second wood structural member,
- wherein the first wood structural member and the second wood structural member have an overlapping intersection and form a third surface which is obscured by the connection;
- and
- a coating consisting essentially of a two-component polyurea, and wherein the coating substantially covers at least 60% of the overlapping intersection between the first and the second wood structural members, and
- wherein the coating substantially covers the first wood structural member and the second wood structural member at least about 1.0 cm from the intersection of the first and second wood structural members.
A method for increasing the net deflection of structural framing members before failure of a connection between a first wood framing member and a second wood framing member in a wood framing structure, comprising:
- connecting a portion of a first wood framing member and a portion of a second wood framing member by a connection means to form a connection,
- wherein the first and second wood framing members have an overlapping intersection and form a third surface which is obscured by the connection,
- applying a coating to the connection of the first and second wood framing members of at least 60% of the length of the connection between the first and the second wood framing members with a coating liquid consisting essentially of a two-component polyurea to form a covering.
