Method and system for mounting building wall panels to building frames, incorporating mounting means elements with two degrees of motion freedom

An insertional frame for use in a building wall panel mounting system, which insertional frame comprises:

• a. a mounting means element,
• b. a mounting means element holding bracket,
• c. an inner mounting means element holding bracket retainer, and
• d. an outer building wall panel engaging element, which mounting means element is held within the mounting means element holding bracket between a top aspect and bottom legs thereof, in a fashion allowing the mounting means element to slide along the length of the mounting means element holding bracket, and which mounting means element holding bracket is positioned within a space formed between the inner mounting means element holding bracket retainer upper surface and the inner top and side surfaces of the outer building wall panel engaging element when the former is placed inside the latter and oriented so that the outer sides of the former contact the inner sides of the latter and the top aspects of both the former and latter are coplanar when the insertional frame is viewed in elevation from the side or end thereof, in a fashion allowing the mounting means element holding bracket to move within the identified space along the length of the inner mounting means element holding bracket retainer, which motion is perpendicular to the motion allowable to the mounting means element in the mounting means element holding bracket, which outer building wall panel engaging element has tapered sides as viewed in elevation from the end of the insertional frame, and which mounting means element holding bracket has a shape which causes the outer sides thereof to snuggly, but slideably, fit between the inner sides of the outer building wall panel engaging element, while the lower leg extremities of the mounting means element holding bracket sit on the upper surface of the lower portion of mounting means element bracket retainer.
