Monolithic concrete wall expansion joint system
First Claim
1. A concrete wall structure joint system for mitigating against crack formation in a wall, the system comprising:
- a first concrete wall component defining an upper surface;
a second concrete wall component defining an upper surface; and
a joint for mitigating against crack formation in the first and second concrete wall components, the joint comprising;
a rigid plate disposed between the first and second concrete wall components, an upper edge of the rigid plate being lower than the upper surfaces of the first and second concrete wall components;
a depression formed in the upper surfaces of the first and second concrete wall components, the depression formed above the rigid plate.

Abstract
An expansion joint system for a wall is provided herein wherein a first concrete wall component is substantially separated from a second concrete wall component via a rigid plate such that contraction of the first concrete wall component does not create significant stresses in the first or second concrete wall component so as to create cracks in the first or second concrete wall component. Moreover, a compressible material may be disposed between the rigid plate and/or the first and/or second concrete wall component such that expansion of the first concrete wall component compresses the compressible material instead of imposing significant stresses on the first or second concrete wall component so as to be likely to form cracks in the first or second concrete wall component.

14. A method for forming a concrete wall structure expansion joint in a wall, the method comprising:
-
building first and second concrete wall forms for first and second concrete wall components, respectively; building a joint between the first and second wall forms, the building the joint step comprising the step of; disposing a rigid plate between the first and second concrete wall forms, the rigid plate defining an upper edge; pouring concrete into the first and second concrete forms to form the first and second concrete wall components; forming an upper groove between the upper surfaces of the first and second concrete wall components and above the upper edge of the rigid plate; curing the concrete to form the wall; removing the first and second concrete wall forms. - View Dependent Claims (15, 16, 17, 18)
