US 6,141,937 A · Holder for adjustable positioning of reinforcing rods

Abstract

The current invention is directed to a holder (32) for adjustable positioning of reinforcing rods (49). The holder has a horizontal support structure and a means for holding a reinforcing rod (49). The holder is comprised of a first leg member (33), a second leg member (34), a spring (35) and a retaining member (41). The leg members are elongated for spanning one of the cells of a hollow block (20). The first and second leg members are configured and arranged to create a gap (37) therebetween for receiving the reinforcing rod. The spring is adapted to bias the leg members against the reinforcing rod to vertically suspend and selectively permit adjustment of the vertical position of the reinforcing rod during the construction of a hollow block wall (47). In the preferred embodiment, the leg members and the spring are integrally formed from a continuous wire member having a U-shaped profile. The present invention also broadly comprises a hollow block wall construction incorporating the holders described above, and also a method of constructing a hollow block wall. As the wall is constructed, the holders permit the vertical reinforcing rods to be raised to approximately correspond to the height of the wall under construction.

Dependent claims

A method of constructing a hollow block wall, comprising the steps of:

providing a plurality of hollow blocks each having a cell extending therethrough;
joining said hollow blocks in end-to-end horizontal relationship with a cementitious binder material to form a first course of blocks;
providing successive courses of blocks atop said first course to form a plurality of stacked courses;
said courses joined by a cementitious binder material and arranged such that said cells of said hollow blocks form hollow cores extending vertically through said successive courses;
providing at least one holder for vertically positioning a reinforcing bar within at least one of said cores;
positioning said holder to span said one of said cores;
inserting a vertical reinforcing rod within said one of said cores and engaging said holder such that said rod is vertically suspended within said core;
laying additional successive courses of blocks atop the highest existing course of blocks;
selectively vertically adjusting said reinforcing rod within said holder as said additional courses are laid such that the upper end of said rod is vertically raised to approximately correspond to the height of said additional courses;
and
filling at least one of said cores with a cementitious binder material.
