Unibody structural frame for an interlocking structural block, an interlocking structural block, and a system of interlocking structural blocks

A unibody structural frame for an interlocking structural block comprising:

• a plurality of struts connected with a web, each strut having a top portion, an outer surface, and an inner surface, wherein each strut is configured for engagement of a top portion of one frame within a recess of the inner surface of the strut of another unibody structural frame, the web holding the struts to which it is connected in relative rigid spacial symmetry and thus preventing the struts from rotation or translation about any axis with respect to any other strut connected to the same web;
• an opening into the inner surface of a strut at the bottom end of each strut, the opening configured for engagement with the top portion of the outer surface of a strut of an adjacent structural block;
• the web including
• a plurality of lengthwise web members extending in a first direction;
• and
• a plurality of cross members extending in a substantially orthogonal direction to the first direction;
• each member of the plurality of lengthwise web members and of the plurality of cross members having a first end and a second end, wherein each member is connected to two adjacent struts, and wherein each member has a first, bottom flat edge, and a second, upper and opposite arcuate web edge providing more attachment length at a joint between an edge of the web and the strut to which that edge attaches, and less material in the web nearer a centre point between the two struts to which the web is attached;
• wherein at least a pair of the lengthwise web members extends between each adjacent pair of struts and further comprising a lengthwise opening between the pair of the lengthwise web members;
• and
• wherein at least a pair of the cross members extends between each adjacent pair of struts and further comprising a widthwise opening between the pair of the cross members.
