Tension membrane structure wrinkle elimination

A construction system for a tension membrane structure provided with a plurality of semi-elastic membranes adjacent to each other, and comprising at least one structural member whose length is greater than said structural member's width and which has a side extending along the length of said structural member comprising two oppositely disposed substantially parallel edges and a centrally disposed slot extending along said side, an adjustable membrane support positioned on said side of said structural member between one edge thereof and said centrally disposed slot, said adjustable membrane support having a portion adapted to support and hold the side of a membrane section which is positioned adjacent to a side of said structural member, and said support being provided with adjustable means to draw that portion of said membrane support which is supporting and holding the side of said membrane section toward, but not into, said centrally disposed slot in said structural member between said structural member's two sides so that said membrane section will become tightened and wrinkles therein will be minimized or eliminated.
