Light transmission panels, retaining clip and a combination thereof

A glazing panel system providing light transmission there through comprising:

• a first glazing panel of plastic;
• an upstanding seam flange on an end of the glazing panel and being joined at its lower end to the first glazing panel;
• a first end on the first glazing panel;
• a second glazing panel of plastic;
• a first end on the second glazing panel;
• an upstanding seam flange joined at its lower end to the first end of the second glazing panel;
• a retention clip being disposed between adjacent first ends of the first and second glazing panels and being adjacent their respective upstanding seam flanges;
• a base flange on the retention clip for connection to a lower support;
• a pair of faced-to-face upstanding web sections on the retention clip disposed between the adjacent seam flanges and joined at their lower ends to the base flanges;
• a welded portion joining the face-to-face-upstanding web sections together to form an upstanding central web for the retention clip;
• a top flange joined to an upper end of the upstanding central web and projecting laterally and engaging the seam flanges to hold the same against uplift forces;
• and
• raised portions in the top flange to stiffen the same to resist bending by the upstanding seam flanges experiencing the uplift forces.

A retention clip for architectural panels having upstanding seam flanges adjacent one another and seam between adjacent panels, comprising:

• a metal body;
• a pair of central web sections defining a central web disposed face-to-face and for being positioned at the seam between upstanding seam flanges;
• a base on the metal body integral with a lower end of the central web sections and for connection with a central support for the panels;
• and
• a pair of adjacent top flange sections joined to the central web and extending outwardly from the central web to hold the respective glazing panels against uplift forces.

A retention clip for architectural panels having upstanding seam flanges adjacent one another and a seam between adjacent panels comprising:

• a one piece, folded metal body;
• an upstanding central web on the metal body having two adjacent web sections disposed face-to-face and for being positioned at the seam between the upstanding seam flanges;
• a base flange on the metal body integral with a lower end of the central web and for connection with a support for the architectural panels;
• a weld portion joining the upstanding web sections together;
• a folded top flange on the metal body formed with upper and lower flange sections each extending outwardly from the central web to restrain the respective architectural panels against forces trying to separate the architectural panels from each other and form the support;
• and
• ribs formed in the folded top flange to strengthen the top flange.

A method of making a retention clip for glazing panels with a top flange, a central web, and a bottom flange from a piece of bendable and foldable sheet of metal, the method comprising:

• providing a bendable and foldable sheet of metal;
• bending a central portion of the sheet of metal to have a two ply top flange for holding the glazing panels against uplifting forces;
• placing together portions of the sheet of metal adjacent to and integral with the top flange to form a two ply, central web which will be upstanding on the retention clip;
• bending at least one end of the sheet metal adjacent the central web to be at an angle to the central web and thereby form a base flange;
• and
• welding together the central web plies to form a stronger central web for resisting forces being applied by the glazing panels to the retention clip.

A retention clip for first and second architectural panels having upstanding seam flanges adjacent one another and having a seam between the adjacent panels comprising:

• a first folded metal body;
• a second folded metal body;
• an upstanding central web on each of the first and second folded metal bodies for being positioned at the seam between the upstanding seam flanges;
• a first base bent outwardly from the central web on the first metal body for extending in a first direction beneath the first glazing panel;
• a base bent outwardly in an opposite direction from the direction of the first body base and extending beneath the second glazing panel;
• and
• a top flange on the first and second metal bodies extending outwardly from their respective webs to hold the respective panels against forces trying to separate the panels from each other.
