Gutter Pan Slope

For roof slopes less than 6 on 12 the upper roof pan is attached to a locking strip soldered to the lower pan.

Gutter pan slope.

For example if you have 30 feet of guttering the calculation is 1 4 x 3 0 75 i e. This grade adjustment can be accounted for in the patching that is required when replacing old curb and gutter sections. So if you have a 25 foot section of guttering you should set the downspout end of the gutter 5 8 of an inch lower 1 4 x 2 5 5 8 than the other end. Steep counter slopes will cause some wheelchairs to catch on back rollers and lose drive wheel traction.

See example table 8 8a. The lower pan is cleated to the roof deck with the indicated clearances determined by expansion calculations. The common design treatment for a road is a concrete gutter that is built to match an asphalt lane. Most contractors tend to set the slop at one quarter inch per ten feet of guttering.

As a general rule gutter slope is set at 1 4 inch per 10 feet of guttering. Figure x02 4 h counter slope conditions. Sectional view of wheelchair at a counter slope condition with grades indicating the algebraic differences and limitations. The slope of the gutter must be transitioned from the standard 1 12 slope to a 1 20 slope.

There will be minimal grade adjustments necessary where the flatter gutter pan matches the existing street surface approx. Let s explore that further. So what s the ideal amount of slope for your gutters. The concrete gutter is oftentimes at a different slope than the asphalt lane and its surface is rarely flush with the lane.

This means the downspout end of the gutter should be set 3 4 of an inch lower than the other end.
