Method for assembling cobblestones into mats and device for carrying out thereof

Abstract

A cobblestone mat usable for covering roads, sidewalks, patios, outside/inside walls, etc., is disclosed, comprising a plurality of predeterminedly shaped cobblestones disposed at a certain distance to each other and a binding net internally imparted into and joining the cobblestones. A method is provided for assembling concrete cobblestones and the net, comprising the steps of providing a mold for forming the mat, predeterminedly placing the net into the mold, pouring liquid concrete into therein, hardening the concrete, forming the mat, and extracting the mat from the mold. An automated device for making the mat is proposed. There are also described preferable shapes and sizes of the cobblestones and cobblestone mats. The invention permits achieving high quality covering even by low-experienced workers, expediting the covering, minimizing dust and noise at work site since it avoids cutting the cobblestones, decorating surfaces with imitation of natural stone appearance and various colors and designs.

1 . An article of manufacture called a cobblestone mat usable for covering roads, driveways, sidewalks, outside and inside walls, etc., comprising:
 a plurality of cobblestones of predetermined shapes disposed at a predetermined distance to each other; and   a binding net composed of predeterminedly strong ropes having a number of rows and a number of columns, said ropes made of cotton or polyethylene, said binding net internally imparted into and joining said cobblestones.   
   
   
       2 . The article according to  claim 1 , wherein said cobblestones made of concrete. 
   
   
       3 . The article according to  claim 2 , wherein said cobblestones having a base of a squared shape. 
   
   
       4 . The article according to  claim 2 , wherein said cobblestones having top uneven surfaces imitating a natural stone look. 
   
   
       5 . The article according to  claim 2 , wherein said cobblestones having a size in the range from 25 to 200 mm. 
   
   
       6 . The article according to  claim 2 , wherein the predetermined distance ranging from 5 to 10 mm. 
   
   
       7 . The article according to  claim 2 , wherein the height of said cobblestones is 40 mm. 
   
   
       8 . (canceled) 
   
   
       9 . A device for assembly of concrete cobblestones and a binding net into a cobblestone mat, said device comprising:
 a mold means for forming said cobblestone mat;   a means for orderly keeping and supplying the binding net to the mold means, said means for orderly keeping and supplying disposed at a predetermined distance from the mold means;   a driving means for moving the binding net to the mold means, said driving means disposed at a predetermined distance from the means for orderly keeping and supplying;   a guiding means receiving the binding net from the driving means, said guiding means disposed at a predetermined distance from the driving means;   a cutting means for cutting a predetermined piece of said binding net disposed at a predetermined distance from the guiding means;   a pushing means for pushing the binding net into the mold means, said pushing means disposed above the mold means, said pushing means partially coupled to said cutting means;   a dragging means for capture the binding net and predeterminedly positioning it above the mold means, said dragging means disposed at the opposite side in relation to said guiding means;   executing means for actuation of said driving means, said pushing and cutting means, and said dragging means, predeterminedly disposed in relation to said driving means, said pushing and cutting means, and said dragging means; and   a control means for controlling said executing means, predeterminedly connected to said executing means.   
   
   
       10 . The device according to  claim 9 , further comprising a regulative means capable to adjust said dragging means to a changing width of the binding net for proper engagement. 
   
   
       11 . A method for assembly of concrete cobblestones and a binding net into a cobblestone mat, comprising the steps of:
 providing a mold means for forming said cobblestone mat;   providing a driving means for moving said binding net to the mold means;   providing a pushing means for pushing said binding net into the mold means;   providing a dragging means for capture of said binding net and positioning it;   actuating said driving means and moving said binding net to the mold means;   engaging said binding net at predetermined points by said dragging means and predeterminedly positioning said binding net in relation to the mold means;   engaging said pushing means with said binding net at the predetermined points;   disengaging said dragging means from said binding net;   cutting a predetermined piece of said binding net;   fixing said binding net within said mold means;   filling said mold means with concrete;   hardening the concrete; and   extracting the resultant hardened concrete cobblestone mat from the mold means.
