Benefits of technology

[0006]It is an object of the present invention to provide an apparatus to enable masons to secure a string line along a course of CMU's or bricks. This apparatus is easy to use, and mitigates potential safety hazards on a construction site.

Problems solved by technology

If various concrete masonry units (hereafter CMU's), or other building materials are not positioned accurately, a lot of serious problems may unnecessarily ensue.
Unfortunately, this process of placing a weighted object on a twig can bring about serious hazards on a construction site.
And by the time the object reaches ground level, its acceleration can potentially cause serious injury to those below.
In other instances, it can also cause expensive property damage.

Embodiment Construction

[0022]According to a preferred embodiment of the present invention, a unique apparatus is disclosed which enables users to secure a tight string line with respect to either concrete masonry units (CMU's) or bricks. The present invention obviates the need for twigs, and other objects typically used therewith. The present invention is described in enabling detail below.

[0023]FIG. 1 illustrates a preferred embodiment of the present invention. A Masonry Line Stabilizing Apparatus for use with CMU's 100 incorporates an elongate member 101. This elongate member, in some preferred embodiments is made of a flexible sheet of metal. The flexibility of the metal enables portions of the apparatus to be biased between the cell of a CMU (Concrete Masonry Unit) and the web.

[0024]FIG. 13 contrasts the present invention with the prior art. Typically, many construction workers use a twig 502 which holds a line in place along a course of CMU blocks. And in order to stabilize the twig, workers use vari...

Abstract

A Masonry Line Stabilizing Apparatus for use with CMU's and Bricks incorporates an elongate piece of metal with biasing faces, which secure a string line longitudinally through a string stabilizing lip.

Description

FIELD OF THE INVENTION[0001]The present invention is in the area of construction, and more particularly relates to an apparatus for holding string lines with respect to concrete masonry units (CMU's) and bricks.BACKGROUND OF THE INVENTION[0002]One of the most crucial aspects of construction work is to ensure that the building process adheres strictly according to measurements. If various concrete masonry units (hereafter CMU's), or other building materials are not positioned accurately, a lot of serious problems may unnecessarily ensue.[0003]In order to ensure that a course of CMU's is appropriately lined up, masons use a string line which is stretched from one end to another. Typically, one mason will position himself in the center of the course and place a twig there in order to stabilize the string line. In addition, the mason will often place an object on top of the twig to make sure that the string line does not sag in the middle of the course.[0004]Unfortunately, this process ...
