Problems solved by technology

Because it is desirable to build the wall to its final height prior to inserting the reinforcing bar, a problem arises regarding how to tie the reinforcing bars together inside the wall cell.
Such a solution is undesirable because it requires subsequent repair of the wall.
This method is labor intensive and therefore slower than other methods.
However, this system lacks a mechanism to insure the tied bars in centered in the cell.

Embodiment Construction

[0028] Referring now to the drawings in which like reference numerals indicate like parts, and in particular, to FIGS. 1-5, one aspect of the present invention is a device 20 for tying and centering a first reinforcing bar 22 and a second reinforcing bar 24 within a cell 26 of a concrete block 28. In one embodiment, a housing 30, which contains a tie 32 and at least one centering portion 34, is positioned over cell 26. Tie 32 is used to tie reinforcing bars 22 and 24 to one another and at least one centering portion 34 ensures that the tied reinforcing bars are positioned substantially at a center 35 of cell 26. Housing 30 protects tie 32 and other components from being damaged by contacting wet mortar or reinforcing bars 22 and 24.

[0029] As best shown in FIG. 5, housing 30 includes a base portion 36, a skirt portion 38 that is adapted to fit within the base portion, and a cover portion 40 that is adapted to cover both the skirt portion and the base portion.

[0030] Base portion 36 ...

Abstract

A device for tying and centering reinforcing bars within a cell of a concrete block. A housing adapted to be positioned adjacent the cell contains a tie, which extends from the housing. The tie includes a loop, a free end, at least one centering portion that engages the housing at one end and the loop at an opposite end, and teeth. The at least once centering portion is adapted to position the loop substantially within the center of the cell when the loop is closed around the reinforcing bars. When the free end is pulled, the loop is closed and substantially centered within the cell. Either the housing or the loop itself include a ratchet portion having teeth, which engage the teeth of the tie and hold the loop in a closed position after the free end of the tie is pulled.

Description

BACKGROUND OF THE INVENTION [0001] (1) Field of the Invention [0002] The present invention generally relates to a device for tying and centering reinforcing bar. In particular, the present invention is directed to a device for tying and centering reinforcing bar in a cell of a concrete block. [0003] (2) Description of the Related Art [0004] Concrete block construction is a common method for building walls in both residential and commercial structures. The typical block is a rectangular concrete block, which includes two openings or cells formed through the block. The concrete blocks are stacked on one another. A thin layer of mortar is positioned between the blocks to join them together. [0005] After construction of the wall is completed, the cells of the blocks develop a matrix, which can be filled with concrete to increase the strength of the wall. Typically, steel reinforcing bar is positioned in the cells and extended vertically through the cells prior to filling the cells with ...
