Shear wall attachment assembly and method of use
View Patent ↗The present invention is a raised floor assembly efficiently connecting a pre-fabricated shear wall to a foundation in applications other than slab-on-grade. The raised floor assembly includes an engineered wood material block machined to accept a connecting rod therethrough. The raised floor assembly also includes a connecting rod that is configured to attach at one end to a pre-fabricated shear wall and is coupled at the other end to an anchor bolt. Additionally, a transfer plate may be positioned between the pre-fabricated shear wall and the top of the engineered wood material block. The transfer plate provides a bearing surface for the pre-fabricated shear wall and helps maintain connecting rod alignment. A transfer plate may also be provided underneath the engineered wood material block and above the foundation. Additionally, a variety of spacers may be provided between the bottom of the engineered wood material block and the foundation.
1. A pre-fabricated shear wall attachment assembly for attaching a pre-fabricated shear wall to an anchor bolt, comprising:
a block of engineered wood material, said block including a groove extending therethrough, said block of engineered wood being positioned between the pre-fabricated shear wall and the anchor bolt;
a coupling rod, said coupling rod being configured to attach the pre-fabricated shear wall to the anchor bolt, at least a portion of the coupling rod being within the groove; and
a transfer plate positioned between the pre-fabricated shear wall and the block of engineered wood material, said coupling rod passing through said transfer plate.
2. The pre-fabricated shear wall attachment assembly of claim 1 , further comprising spacers positioned between the block of engineered wood and the anchor bolt.
3. The pre-fabricated shear wall attachment assembly of claim 1 , wherein the block of engineered wood product is a laminated strand lumber product.
4. The pre-fabricated shear wall attachment assembly of claim 1 , wherein the block of engineered wood product is comprised of strands and the strands of the block of engineered wood product are substantially parallel with the groove.
5. The pre-fabricated shear wall attachment assembly of claim 1 , furthering comprising a sheathing attached to the transfer plate;
one or more joists positioned under the sheathing, the grooves on the block being positioned opposite of the joists.
6. The pre-fabricated shear wall attachment assembly of claim 5 wherein the block has a top and a bottom, the top being substantially level with the sheathing.
7. A pre-fabricated shear wall attachment assembly for attaching a pre-fabricated shear wall to an anchor bolt, comprising:
a block of engineered wood material, the block including a groove extending through a first side, the block of engineered wood being positioned between the pre-fabricated shear wall and the anchor bolt;
a coupling rod, the coupling rod being configured to attach the pre-fabricated shear wall to the anchor bolt, at least a portion of the coupling rod being within the groove; and
a transfer plate positioned between the pre-fabricated shear wall and the block of engineered wood material, the coupling rod passing through the transfer plate;
a sheathing attached to the transfer plate; and
one or more joists positioned under the sheathing, the grooves on the block being positioned opposite of the joists.
8. The pre-fabricated shear wall attachment assembly of claim 7 wherein the transfer plate transfers shear loading from the shear wall and coupling rod, into the engineered wood material block, and then back into the coupling rod, to be dissipated into the anchor bolt.
9. The pre-fabricated shear wall attachment assembly of claim 7 wherein the pre-fabricated shear wall is attached to a foundation, the foundation, being a non-slab-on grade foundation.
10. The pre-fabricated shear wall attachment assembly of claim 7 wherein the block of engineered wood product is a laminated strand lumber product, the laminated strand product being comprised of strands, the strands being substantially parallel with the groove.
