Squaring a new deck frame is a crucial step to ensure the structure is built correctly with 90-degree corners, making subsequent decking and railing installation much easier and more accurate. Based on common practices and the provided reference, a straightforward method involves measuring the diagonals.
Understanding Deck Squaring
Squaring a deck frame simply means ensuring that all four corners form perfect 90-degree angles. This results in a rectangular (or square) shape where opposite sides are parallel and equal in length. The provided reference indicates that you don't need special calculations or ratios to achieve this.
The Fool-Proof Method: Measuring Diagonals
A reliable way to square a deck frame, particularly once the perimeter boards are in place, is by comparing the lengths of its diagonals.
Here's how the method works, using information from the reference:
-
Tools:
- An accurate measuring tape in good condition.
- A second tape measure (the reference mentions using two tape measures for this step).
-
The Principle: A rectangle (or square) is perfectly square when its two diagonals (measured from opposite corners) are exactly equal in length. If they are unequal, the frame is not square.
Step-by-Step Guide
Follow these steps to square your deck frame using the diagonal method:
- Ensure Perimeter is Ready: Make sure the perimeter boards are in place.
- Measure Diagonals: Using your measuring tapes, measure opposite corners. Measure from the inside corner point of one corner to the inside corner point of the diagonal opposite corner.
- Compare Lengths: Note the length of the first diagonal. Measure the second diagonal (the other pair of opposite corners).
- Adjust the Frame: If the two diagonal measurements are not equal, the frame is not square. You will need to adjusting the frame as needed. This usually involves gently pushing or pulling one of the corner connections until the diagonal measurements match. This might require temporary bracing.
- Re-Measure: After making adjustments, re-measure both diagonals to confirm they are now equal. Repeat adjustments until they are the same length.
Quick Reference Table
| Step | Action | Notes |
|---|---|---|
| Preparation | Ensure perimeter boards are installed | The frame needs to be mostly assembled. |
| Measurement | Measure diagonal 1 (corner to opposite) | Use an accurate tape measure. |
| Measurement | Measure diagonal 2 (other corner to opposite) | Use a second tape measure simultaneously. |
| Comparison | Compare Diagonal 1 and Diagonal 2 lengths | They must be equal for the frame to be square. |
| Adjustment | Adjust the frame as needed | Push or pull corners until diagonals match. |
| Verification | Re-measure diagonals after adjustment | Confirm they are equal before proceeding. |
By using an accurate measuring tape and comparing the diagonal measurements while adjusting the frame as needed, you can easily and effectively square your new deck frame without needing complex calculations.
