Truss-wall installation system and related methods
View Patent ↗A method for installing a truss-wall stud unit includes coupling a set of bottom plates with a foundation, coupling a set of hinge brackets with the set of bottom plates, coupling a first partial truss with a second partial truss to form a truss-wall stud unit, coupling the truss-wall stud unit with the bottom plates and hinge brackets, and hoisting the truss-wall stud unit into a substantially vertical position. A system includes truss-wall stud units which are connected to bottom plates using hinge brackets. Once connected to the hinge brackets and bottom plates, the truss-wall stud units are hoisted upright into a substantially vertical position using a cable system with a cable support system. Temporary interlocking spacer bars are used to brace the truss-wall stud units at predetermined intervals.
1. A method for installing a truss-wall stud unit, the method comprising:
coupling a first bottom plate to a foundation, and coupling a second bottom plate to the foundation, said first and second bottom plates being substantially parallel to each other;
coupling a first hinge bracket to said first bottom plate, and coupling a second hinge bracket to said second bottom plate;
positioning a first partial truss in relation to a second partial truss at the installation site, wherein each of the first and second partial trusses comprise a stud leg portion and a roof truss portion and said roof truss portion of said first partial truss is proximate said roof truss portion of said second partial truss;
coupling a first partial truss with a second partial truss at the installation site to form a truss-wall stud unit wherein the roof truss portion of the first partial truss is coupled to the roof truss portion of the second partial truss using one of the combination of a peak bracket and lower connection plate, or the combination of a standard gusset plate and a bottom chord splice bracket;
coupling the stud leg portion of the first partial truss to said first hinge bracket and coupling the stud leg portion of the second partial truss to said second hinge bracket after the first hinge bracket and the second hinge bracket are coupled to the respective bottom plate the; and
hoisting the truss-wall stud unit into a substantially vertical position by applying a hoisting force to the roof truss portions of the truss-wall unit for pivoting the truss-wall stud unit about an axis of rotation defined by the first and second hinge brackets.
2. The method as recited in claim 1 , wherein the coupling the stud leg portion of the first partial truss to the first hinge bracket and coupling the stud leg portion of the second partial truss to the second hinge bracket step further comprises bending a portion of each of the hinge brackets and fastening the bent portion of the bracket to the respective stud leg portion of the truss-wall stud unit.
3. The method as recited in claim 1 , further comprising coupling an end hinge bracket to each bottom plate near a terminal end of each bottom plate, coupling an end truss-wall stud unit to the bottom plate with the end hinge bracket, and hoisting the end truss-wall stud unit into a substantially vertical position.
4. The method as recited in claim 1 , further comprising installing lateral bracing within the truss-wall studs.
5. The method as recited in claim 1 , further comprising threading a hoist cable through a passage in one of a second peak bracket or a second bottom chord splice plate of a second truss-wall stud unit that was previously raised into a substantially vertical position and connecting the hoist cable to one of the peak bracket or the bottom chord splice plate of the truss-wall stud unit after said threading step and prior to said hoisting step.
