Methods and apparatus for support channel
Methods and apparatus for a support channel according to various aspects of the present technology comprise a support channel having a strengthening ridge positioned along a closed end of an open channel body. The ridge may extend along the length of the channel body to increase a load bearing capacity of the channel body as compared to a similar shaped body without the ridge. The ridge may comprise a rounded protrusion extending outward from the dosed end of the channel, body in a manner that provides additional resistance to loading forces.
1. A support channel, comprising:
a channel body having a first end and a second end, wherein the channel body comprises:
a pair of opposing straight sidewall elements extending between the first and second ends, wherein:
the sidewall elements are separated by a gap defining a channel width; and
each sidewall element comprises a terminating end portion and a transition point;
a first transition element extending from the transition point of one of the sidewall elements towards a first inflection point proximate a center of the gap;
a second transition element extending from the transition point of the remaining sidewall element towards a second inflection point proximate the center of the gap; and
a ridge positioned at the center of the gap and extending between the first inflection point and the second inflection point, wherein the ridge:
comprises a protrusion extending downwardly beyond the first and second inflection points; and
extends along a length of the channel body between the first and second ends; and
a first flange disposed at the first end proximate the ridge and a second flange disposed at the second end proximate the ridge, wherein each flange comprises a substantially flat surface extending outwardly from the ridge.
2. A support channel according to claim 1 , wherein the ridge comprise a substantially rounded surface having an inner diameter of between one thirty-seconds of an inch and one-quarter of an inch.
3. A support channel according to claim 1 , wherein the first and second transition elements are curved concave relative to the center of gap to form a substantially u-shaped channel body.
4. A support channel according to claim 1 , wherein the first and second transition elements each comprise:
a first substantially linear wall segment extending from the ridge towards one of the sidewall elements, wherein the first substantially linear wall segment comprises a first angle relative to a horizontal axis of the support channel; and
a second substantially linear wall segment extending from the first substantially linear wall segment towards one of the sidewall elements, wherein:
the second substantially linear wall segment comprises a second angle relative to a horizontal axis of the support channel; and
the second angle is larger than the first angle.
5. A support channel according to claim 1 , wherein the pair of opposing straight sidewall elements are parallel to each other between the first end and the second end of the channel body.
