Demountable/modular structure system

A universal stud, comprising:

• a first female edge;
• a male edge, wherein the male edge is complementary to, and configured to be engageable with an adjacent universal stud;
• a cam lock, wherein the cam lock comprises:
• a cam hook disposed in a hook slot of the at least one male edge,
• an interior lip disposed on the cam hook, and
• a rotatable eccentric hook disposed at least partially in an aperture defined by the cam hook, wherein the eccentric hook is configured to engage with the interior lip;
• and
• a cam pin disposed in a cam slot of the first female edge,
• wherein rotation of the eccentric hook causes engagement with the cam hook, rotation of the cam hook, and lateral translation of the cam hook.

A demountable structure, comprising:

• a first demountable structural panel comprising a first universal stud;
• and
• a second demountable structural panel comprising a second universal stud;
• wherein each of the first universal stud and the second universal stud comprises:
• a first female edge;
• a male edge, wherein the male edge is complementary to, and configured to be engageable with an adjacent universal stud;
• a cam lock, wherein the cam lock comprises:
• a cam hook disposed in a hook slot of the at least one male edge,
• an interior lip disposed on the cam hook, and
• a rotatable eccentric hook disposed at least partially in an aperture defined by the cam hook, wherein the eccentric hook is configured to engage with the interior lip;
• and
• a cam pin disposed in a cam slot of the first female edge,
• wherein rotation of the eccentric hook causes engagement with the cam hook, rotation of the cam hook, and lateral translation of the cam hook.
