Abstract
A rebar support chair has a housing with first and second opposed boundary walls spaced apart from one another and defining a cavity therebetween, an attachment portion having a seat for supporting rebar, a dampening member, and a force dispersion member inside the cavity. The attachment portion transfers forces between the rebar and housing. The force dispersion member moves in response to vibration of the attachment portion, and movement of the force dispersion member corresponds with compression and decompression of the dampening member. Another rebar support chair has a housing defining a cavity, an attachment portion for supporting rebar, a dampening member, and a force dispersion member in the cavity. The attachment portion transfers forces between the rebar and housing. The force dispersion member moves from a rest position in response to vibration of the attachment portion, and the dampening member biases the force dispersion member toward the rest position.
