STEP 3: ASSEMBLING THE TRUSS

Note: The two end trusses

will have no collar tie or bracing. The basic interior truss has a collar tie and the W web

Assembly. Many of the buildings will require the use of knee braces in the corners. All trusses have the corner brackets.

When one or both ends of a truss are located over a side garage door the eave corner may be cut down to fit (see your

drawing package) In locations that have a heavy snow load or a high wind load the truss/knee brace design may have to be

changed (see your drawing package). Some buildings 24’ wide and under may have a truss brace with out the web. A type 2

or standard truss brace will have one center vertical 1 1/2” square with BK-30 brackets at both ends.

A typical truss frame has 13 basic parts: 1 peak, 2 rafters, 2 eave corners, 2 corner brackets, 1 collar tie center tube,

2 collar tie end tubes, 2 collar tie brackets (1 left & 1 right), 2 inside web braces. 2 outside web braces and 6 brace brackets

with hardware. The knee braces (two) are not required on all buildings. The length of rafters and braces will depend on the

width of the building. (Note, your building may have a different truss. See your drawings for truss brace layout)

ASSEMBLY: Use #12 x 3/4” self-drilling screws and screw gun with 5/16” socket with extension in all assembly operations.

1. Install a rafter on both ends of the peak. Use 4 screws in each joint

2. Install a eave corner at the other end of each rafter. Before you install screws, measure from the outside of one eave

corner to the other and set the dimension at the building width. (Example 30’, 40’ or 50’) Keep the joint spaces equal on

both sides of the assembly. This will keep the peak centered in the building. Use 4 screws in each joint.

3. Attach eave corner brackets (shipped unbent) to the eave corner by bending the bracket around the eave corner. Use a

straight edge to ensure that the bracket is flush against the eave corner. Install 2 screws on each side of the truss at

both ends of the bracket. This will require turning the truss over.

4. Join the 3 collar tie pieces. (1 collar tie center tube and 2 collar tie end tubes) Use a straight edge to make sure the

assembly is straight and install 8 screws in each swage joint.

5. Attach a right collar tie bracket on one end of the assembly and a left collar tie bracket on the other end. Fill all of the

screw holes.

6. Center the collar tie assembly in the frame (approximately 18” from outside of truss) and attach the brackets to the eave

corners. Fill all of the screw holes.

7. The web braces are 1” square tubes with flattened ends and 1 hole. The length of a web brace is from the center of one

hole to the center of the other hole. Braces are attached to the brackets with 3/8” x 1 1/4” hex bolts, lock washers and

nuts. The brackets are attached to the frame with 3 self-drilling screws . Two braces can be bolted to the same bracket.

Install the first 2 brackets on the under side of the peak about 7 3/4” from the center line of the building.

Attach one end of the inside (longer) brace to the bracket. Do not tighten at this time. (x2)

Attach the other end of the inside brace to another brace bracket on the same side as the other bracket. (x2)

Attach a outside (shorter) brace to the opposite side of the same bracket. Do not tighten at this time. (x2)

Attach the other end of the outside brace to another brace bracket on the same side as the other bracket. (x2)

Make sure that the collar tie is straight and attach the brackets with the 2 braces connected to the collar tie. (x2)

Attach final brackets to the rafter and then tighten all bolts and nuts.

8. Knee Braces: Knee braces are the same as web braces. The typical knee brace is 30” long for contractor series build-

ings. You should check with our engineering department to see if nee braces are required on your building. If you are

installing knee braces attach a brace bracket to the under side of the eave corner about 1” from the end of the collar tie.

Attach a Knee brace to the bracket and a bracket to the lower end of the knee brace. Attach the lower bracket to the

lower portion of the eave corner. Repeat on the other opposite end of the truss. Tighten all nuts and bolts securely.
