PROBLEM TO BE SOLVED: To provide a foundation reinforced bar unit heightening connection strength of a base combined reinforcement and a rise combined reinforcement and strength of the base combined reinforcement. SOLUTION: A plurality of bottom reinforcements (12a-12c) are extended in the extension direction of a foundation to be arranged in the width direction of the foundation at prescribed intervals in parallel, and a latticed-base combined reinforcement (11) integrally connecting each bottom reinforcement (12a-12c) by a number of cross reinforcements (13) is provided. A plurality of lateral reinforcements (16a, 16b) are extended in the extension direction of the foundation to be vertically arranged at prescribed intervals in parallel, and a latticed- rise combined reinforcement (15) integrally connecting each lateral reinforcement (16a, 16b) by a number of vertical reinforcements (17) is provided. Lower ends (17a) of each vertical reinforcement (17) are protruded downward, the lower ends (17a) are inverted and bent upward along a lower face of a middle bottom reinforcement (12b) positioned in a center part of a width direction of the bottom reinforcements, and the middle bottom reinforcement (12b) can be rotatably held on the inverted and bent part (17b).
