ES2211313A1 - Method for recovering stone waste, particularly for recovering pieces of granite waste generated in granitera, involves cutting granite residual pieces to give polygonal outline, where irregular face of each cut piece is adapted from mesh - Google Patents

Abstract

The method involves cutting the granite residual pieces (1) to give a polygonal outline, particularly a rectangular outline. An irregular face (3) of each cut piece is adapted from a three-dimensional wire mesh (4). The wire mesh width is according to the thickness of a construction part that is to be obtained. The wire mesh is immersed in a molded concrete mass (5) for configuring the mesh with the residual granite piece prismatic block with the regular faces (2). The wire mesh is fixed by welding multiple steel bars (6) or pipes.

Description

Stone waste recovery method.

Object of the invention

The present invention relates to a method of stone waste recovery, specifically for recovery of the leftover granite pieces in the graniteras, which they are not usually used, in order to obtain with such Waste usable parts in the field of construction.

More specifically this byproduct is applicable for the construction of ships that, economically, acquire a highly decorative look, for farm closures or plots, in general for any field of construction in the that materials with such a level of benefits.

Background of the invention

When the construction of a building is intended based on stone, a classic solution is to use blocks granite, like ashlars, extremely expensive solution, both for the price of the material such as labor for its installation.

A second solution, cheaper for employment of a smaller amount of material, consists in manufacturing first the wall with any other suitable material, as per example with bricks, covering it later with plates of granite thickness considerably smaller than that of the blocks previously mentioned, a solution that although it is a remarkable cost reduction from the point of view of materials, specifically as far as granite is concerned, it entails a increased costs in terms of materials and manufacturing of previous wall and as to the need to make a greater number of cuts in granite and stable fixing operations of said plates to the previous wall.

Both when the original granite pieces are they cut into blocks like when they are cut into plates, in the graniteras produce abundant material residues, which by their dimensions are not usable to obtain blocks or to obtain plates, waste that besides being currently unusable means a significant environmental pollution.

Description of the invention

The method proposed by the invention has been specifically designed to take advantage of this waste, getting on the one hand obtaining usable parts in the construction with similar benefits to the use of conventional granite blocks, but at a cost level considerably less, use that simultaneously supposes a elimination of the contamination problems cited.

To do this, more specifically and from the said residual granite pieces, the invention consists of cut these pieces to give it a formal outline and dimensionally appropriate to the practical use intended for the same, adapt to your irregular face a metal mesh three-dimensional, of adequate thickness to that of the piece to be obtained, and fill said mesh with concrete, obtaining a piece, generally prismatic-rectangular, thick adequate to that of the wall to be obtained, with a substantial part of it based on reinforced concrete and another stone, offering a total or mostly smooth surface, of granite, with a similar aesthetic appearance, once mounted on site, to which would get by mounting granite blocks conventional.

Depending on the intended practical application for the building block, that is, depending on the degree of adhesion that may be necessary between granite and concrete armed, metal mesh can emerge, conveniently welded thereto, a plurality of bars intended for insert into holes previously made in the piece of granite, which with an oblique arrangement ensure a perfect tongue and groove between stone and concrete, which ensures the relative stability between these pieces over time and of indefinitely

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation schematic perspective of a building block obtained with the method of stone waste recovery object of the present invention

Figure 2.- Shows a detail in section transversal of it.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the method that the invention proposes part of the utilization of residual pieces (1) of granite, which when being from cutting operations of large blocks thereof material, have an irregular thickness but a flat (2) face and uniform, which is intended to constitute the face of the block of construction to obtain, while its irregular face (3) is adapts a metal mesh (4), preferably three-dimensional, of width appropriate to the thickness and / or mechanical strength of the block to obtain.

The residual part (1) will be previously cut to provide it with an appropriate contour, such as with the quadrangular contour showing figure 1, and logically the Metal mesh will be contour also suitable to the piece (one).

Once the metal mesh (4) is adapted to the face irregular (3) of the piece (1), a concrete mass (5) is provided appropriate for the mesh (4) to be fully embedded, concrete which will be fixed by adhesion to the irregular face (3) of the piece (1), forming a monobloc set with the latter.

The fixing between these elements, concrete armed (4-5) and residual piece (1) of granite, can be enhanced by the use of fixed steel bars (6) by welding to the metal mesh (4), in the arrangement oblique shown in figure 2, bars intended to be inserted in holes previously made in the residual granite piece (1), holes that will obviously be blind and that will be formal and dimensionally suitable to receive tightly in your inside said bars (6), which can interchangeably materialize in tubes.

In this way a block is achieved prismatic-rectangular, with a perfect finish in all its faces, which offers a front face (2) similar to that of a conventional granite block, which is what has to be your face  seen after its assembly on site, and all with considerable cost reduction, not only because of the residual nature of the granite that participates in the block but also for the easy assembly that involves the same on site, very quickly and with a minimum time consumption

Claims (3)

1. Stone waste recovery method, which being specially designed to recover the granite residual pieces that are generated in a granitera, after cutting the quarry pieces of this material into prismatic blocks or plates, is characterized in that in the The following operational phases are established:
