Panel and Multilayer Panel Structure

A panel comprising:

• a main body comprising,
• a top surface, a bottom surface opposite the top surface, wherein the top surface comprises a top perimeter edge and the bottom surface comprises a bottom perimeter edge,
• a boundary wall extending from the top perimeter edge to the bottom perimeter edge,
• a plurality of interlocking members formed along the boundary wall adapted to engage the corresponding plurality of interlocking members of another panel,
• at least one connecting portion disposed adjacent the boundary wall and on the top surface and adapted to connect a support column for supporting the main body and the support column comprises a connecting end connectable to the main body, wherein the at least one connecting portion is configured to comprise,
• a first alignment pattern adapted to align the connecting end to connect to the at least one connecting portion within the boundary wall when connected, and
• a second alignment pattern adapted to align the connecting end to connect a portion of the connecting end to the at least one connecting portion, wherein the connecting end protrudes out of the boundary wall when connected, wherein the first alignment pattern intersects with the second alignment pattern, wherein the first alignment pattern comprises a circular groove and the second alignment pattern comprises a semi-circular groove, wherein each of the at least one connecting portion comprises a plurality of through holes between the first alignment pattern and the second alignment pattern and wherein the second alignment pattern of the panel when aligned to the second alignment pattern of the another panel, forms the first alignment pattern to align the connecting end to connect to the panel and the another panel.
