ABSTRACT:
An expansion joint lock for transmitting forces between structural members that contract as they are cooled down to operating temperatures. A piston member mounted to one structural member is slidingly engaged with a chamber in a reception member which is mounted to a second structural member. The remaining space in the chamber is filled with a liquid which freezes at a temperature somewhat above the operating temperature of the structure, allowing forces to be transmitted between the structural members by the frozen liquid.
