Which of the following construction joints connects two walls?

The connection between two walls is specifically referred to as a wall-to-wall joint. This type of joint is designed to accommodate the intersection of two vertical surfaces, ensuring structural integrity and adherence to design specifications. Wall-to-wall joints play a crucial role in the overall stability and aesthetic alignment of a structure. These joints not only help manage the forces and loads transferred between the connected walls but also allow for any necessary movement due to settling, thermal expansion, or contraction.

Other types of joints, such as a floor-to-wall joint, typically connect a horizontal surface (the floor) to a vertical one (the wall), while a floor-to-floor joint pertains to connections between horizontal elements on different levels of a structure. A curtain wall does not refer to a joint but rather to a non-structural facade system that typically encloses a building, allowing for more flexibility in design but not specifically denoting the connection of two walls. This reinforces the importance of understanding the specific functions and definitions associated with construction joints in architectural and engineering contexts.
