Anchoring mechanisms for a Binishell

An assembly for erecting a reinforced structure of a hardening building material using a pneumoform, the assembly comprising:

• a pneumoform that is radially asymmetrical in shape and formed of a reinforced material that locks into position once inflated under application of a constant air pressure, the pneumoform having an outer perimeter incorporating a keder;
• an anchor bar having a first portion secured to a foundation and a second portion, wherein the anchor bar has a first hole extending through the second portion;
• a clamp bar configured to be aligned with the second portion of the anchor bar, wherein the clamp bar has a second hole extending through the clamp bar;
• and
• a fixation element extending through a bore created when the first hole and the second hole align, through a portion of the outer perimeter of the pneumoform, and through the clamp bar and the second portion of the anchor bar,
• wherein the outer perimeter of the pneumoform is positionable within a space between the second portion of the anchor bar and the clamp bar such that upon locking the clamp bar to the anchor bar with the fixation element the keder is captured by the clamp bar creating a first seal and forming a fluid-tight internal volume configured to be inflated, and wherein a portion of an external surface of the pneumoform is urged against the keder upon application of pressure against an internal surface of the pneumoform creating a second seal and forming a pocket around at least a portion of the fixation element;
• and
• a matrix of rigid reinforcement bars threaded through a plurality of spacers connecting the matrix of rigid reinforcement bars, wherein the matrix is positioned over the external surface of the locked inflated pneumoform and each spacer is sized to provide measuring guidance for wall thickness of hardening building material applied to the external surface of the pneumoform.
