Abstract
A wire grid shaped with brick size spaces which may be transported or stored as a roll, and which is adaptable for serving as a permanent guide and reinforcement when unrolled onto a flat path with bricks subsequently individually mounted in each of the grid spaces.
Claims2
A rectangular open continuous grid of wire elements which is initially formed as a roll, with the grid shaped of uniformly spaced parallel longitudinal members joined to uniformly spaced parallel lateral members that bound uniform rectangular openings, each opening of the general size of the outline of a brick, together with
- pointed projections perpendicularly mounted at intervals to the members, and projecting from one side of the grid, said projections serving as means to anchor the grid to a flat base upon which it is laid.
