Abstract
A flow-through cap and stirrup for reinforcement bars in a building wall and method of use thereof is disclosed. The building wall is formed from successive layers of masonry blocks having cells therethrough which form a hollow vertical core. Usually and particularly in earthquake prone areas, construction practices include the insertion and grouting in place of a pair of overlapping reinforcement bars within the core formed by the masonry blocks. The device of this invention is a cap and stirrup unit for holding the reinforcement bars in the requisite position. The device is formed from a coil spring with spaced apart coils, and has two elongated cells, namely, a cap portion and a stirrup portion. Each portion has a wall with a closed end and an open end. The cap has a channel which, when installed, accommodates the head of the lower reinforcement bar. Conversely, the stirrup has a channel which, when installed, accommodates the foot of the upper reinforcement bar. The cap and stirrup are connected together so that the predetermined overlap is maintained. Because of the openness of the structure, the cement or mortar used for grouting flows into and through the cap and stirrup portion and bonds the reinforcement bars are within the core of the masonry blocks.
