Methods for Preparing and Installing A Natural Stone Surface and A Tiled Natural Stone Paving System Therefor

Автор: WELSH Michael Allan

Принадлежит:

A system and method are provided for designing/creating, preparing, and installing a natural stone tiled surface at a site that provides a perception of randomness to the observer while actually following a predefined pattern that facilitates simple installation by unskilled trades and allows for the advanced preparation of the stone tiles used. Advanced preparation of the stone tiles allows the offloading of at least some cutting, preparation and installation steps normally required onsite, to an offsite location. In this way, significant time and cost savings can be achieved by shifting time and resources to an offsite location, which minimizes disruptions onsite, allows the building of an inventory of standard shapes, all without compromising the aesthetics or quality of the installation. The system relies on the tessellation or tiling of a specific outline of an irregular concave polygon, that itself includes an internal set of irregular convex polygon shapes. The tessellation of an outline that includes such a set of shapes provides an optical effect that makes it difficult for an observer to recognize the repeating nature of the stones within the patterned outline. 1. A method of preparing a set of natural stone shapes for installation as a tiled surface , comprising:determining a tessellation outline comprising three or more sides;dividing the tessellation outline into a plurality of internal two dimensional shapes; andcutting one or more natural stone slabs into each of the plurality of shapes to form at least one set.2.

Lundell, inventors, which is incorporated in this application in its entirety by this reference.This invention relates to paving stones and blocks, natural and manmade.Paving stones have been in use for thousands of years. Initially such stones were literally that, naturally occurring stones or rocks of various shapes and compositions. Even the earliest installers of such stones recognized that stones of regular shapes and sizes facilitated their installation and effectiveness in use. That doubtless led initially to care in selecting stones and placing them and later to preparatory shaping of stones to facilitate their installation and function. Eventually such regular shapes came to be embodied in man-made bricks and “stones,” including a variety of different shapes and compositions.Notwithstanding thousands of years ...
