Adjustable support systems and methods

A method of assembling an adjustable support system on a structure having a first truss and a second truss, the method comprising the acts of;

• providing an adjustable support system having a plurality of interlocking elements each interlocking element having at least one fastener slot and a cross-section comprising a main rail having a top extension and a bottom extension that define an interior channel and an external periphery, wherein the top extension is longer than the bottom extension, further wherein the plurality of interlocking elements comprises at least one female segment and at least one male segment and the exterior periphery of the at least one male segment fits within the interior channel of the at least one female segment and the fastener slot of the at least one female segment aligns with fastener slot of the at least one male segment when the male segment is situated within the female segment and the interlocking element has a first end and a second end and an assembled length, at least one fastener configured to pass through the fastener slots of the male segment and the female segment to secure the male segment from sliding relative to the female segment, and an attachment point coupled to at least one of the first end and the second end wherein the at least one attachment point is configured to secure the first end or the second end to the at least one truss;
• assembling a first rail by assembling a male segment with a female segment and slidably adjusting the assembled length of the first rail to extend between the first truss and the second truss;
• assembling a second rail by assembling at least one male segment with at least one female segment and slidably adjusting the assembled length of the second rail to extend between the first truss and the second truss
• arranging the first rail a desired distance from the second rail;
• coupling the first end of the first and second rails with the first truss and the second end of the first and second rails with the second truss;
• providing at least one cross rail comprising at least one of the plurality of interlocking elements, a first cross connector and a second cross connector that when assembled span the desired distance;
• and
• securing the first cross connector to the first rail and the second cross connector to the second rail.

A support system for supporting a roof or a floor in a building comprising:

• a plurality of interlocking elements each interlocking element comprising
• a first interlocking element end and a second interlocking element end;
• a female segment having a female segment exterior surface, a female segment interior surface, and at least one female segment fastener slot, and
• a male segment having a male segment exterior surface and at least one male segment fastener slot,
• wherein the female segment fastener slot aligns with the at least one male segment fastener slot when a portion of the male exterior surface of the male segment engages the female segment interior surface of the female segment;
• at least one fastener operable to pass through the female segment fastener slot and the male segment fastener slot to secure the male segment in a position relative to the female segment;
• and
• at least one of an attachment point couplable to at least one of the first interlocking element end and the second interlocking element end wherein the attachment point is operable to secure the first interlocking element end or the second interlocking element end to a truss, and at least one cross-connector couplable to the interlocking element wherein the cross-connector is operable to secure a first interlocking element to a second interlocking element at an angle.
