AI Technical Summary

Problems solved by technology

However, over time, the sand between the joints of the pavers can be washed or blown away
This can cause increased movement of the pavers, which can lead to unevenness and even cracking of the pavers
Since such deteriorating paving equipment would be dangerous, it must be maintained regularly, which is time consuming and expensive

Embodiment Construction

[0038] Numerous changes and modifications will be apparent to those skilled in the art. All such changes and modifications which are apparent to those skilled in the art are deemed to be within the spirit and scope of the invention as broadly presented before and now as described in more detail.

[0039] Referring now to FIG. 1 of the drawings, a paver prestressing device is generally indicated by the reference numeral 10 . The paver prestressing device 10 is typically used with a paved surface assembly 30 comprised of a plurality of paver blocks 32 (see image 3 ). The paver prestressing device 10 serves to increase the interlocking force between the pavers 32 by applying an expansion force when installed between the pavers 32 .

[0040] Broadly, the paver prestressing device 10 includes at least two body elements 12 and 14 (hereinafter "first body element 12" and "second body element 14") arranged along at least one axis Or the arcs 28 may be displaced relative to each ot...

Abstract

The invention provides for a paver pre-stressor apparatus for use with a paved surface having a plurality of pavers. The apparatus includes at least two body members arranged to be displaceable relative to each other along at least one axis or arc. In addition, the apparatus further has as adjustable urging means arranged between the body members. The urging means is configured to adjustably urge the body members away from each other along the axis or arc. Such adjustment of the urging means facilitates compressive interlocking of the pavers when the apparatus is incorporated into the paved surface.

Description

technical field [0001] The present invention relates to a paver pre-stressor, a method of improving a paver pre-stressor, and a method of paving. Background technique [0002] References in this specification to any prior publication (or information derived therefrom), or to any known matter are not, and should not be deemed to be, references to said prior publication (or information derived therefrom) Or the acknowledgment or recognition or any form of suggestion that known things constitute part of the common general knowledge in the technical field involved in this specification. [0003] Paving is a common and popular way of covering surface areas, especially outdoor areas such as sidewalks, yards, patios and driveways. Paving is often used instead of pouring concrete slabs or asphalt. A paving installation generally includes a compacted stone subbase, and a leveled sand bed having a plurality of interlocking paving blocks disposed thereon. The sand is compacted down ...
