Rebar support chair

A rebar support chair configured to be situated in concrete, the rebar support chair comprising:

• a housing having 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, the attachment portion transferring forces between the rebar and the housing;
• a dampening member configured to compress and decompress, the dampening member being positionable against an item selected from the group consisting of the first boundary wall and the second boundary wall;
• and
• a force dispersion member inside the cavity;
• wherein:
• the attachment portion comprises a plurality of notches;
• 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.

• and
• a force dispersion member inside the cavity;
• wherein:
• the seat comprises two arms that collectively define a sufficient perimeter for seating rebar in a passage;
• 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.

A rebar support chair configured to be inside concrete, the rebar support chair comprising:

• a housing defining a cavity;
• an attachment portion having a seat for supporting rebar, the attachment portion transferring forces between the rebar and the housing;
• a dampening member;
• a force dispersion member in the cavity;
• and
• a vibration powered generator configured to convert movement of the force dispersion member into electricity;
• wherein the force dispersion member moves from a rest position in response to vibration of the attachment portion;
• and
• wherein the dampening member biases the force dispersion member toward the rest position.

A section of concrete, comprising:

• rebar;
• a housing defining a cavity;
• an attachment portion extending from the housing, the attachment portion having a seat supporting the rebar, the attachment portion transferring forces between the rebar and the housing;
• a force dispersion member in the cavity, the force dispersion member moving from a rest position in response to vibration of the housing and thereafter returning to the rest position;
• and
• concrete encasing the housing, the concrete not entering the cavity.
