Abstract
An axially elongated performed tube having a leading end and a trailing end. The tube is restricted at its leading end and open at its trailing end for the insertion of an adhesive and a ram to extrude the adhesive. The tube is selectively divided along its length into a plurality of porous axial sections, each section having a porosity different from that of its adjacent section, enabling selected distribution of the adhesive in selected areas.
Claims7
Apparatus for performing in combination with a hardenable thixotropic adhesive, an anchor between spaced masonry elements comprising an axially elongated cylindrically shaped screen sleeve of a length sufficient to substantially pass through said masonry elements and, having a leading end and a trailing end, said screen sleeve being closed at its leading end with an impervious wall and open at its trailing end for the insertion of ram means adapted to extrude the hardenable mass through said screen, said screen sleeve being provided with at least two axial sections each having a different mesh size so as to selectively regulate the amount of hardenable adhesive extruded radially through said screen sleeve along the length thereof selectively filling the spaces between said masonry elements and the screen sleeve and within the masonry elements.
A method for securing masonry elements to a supporting structure, comprising the steps for forming a bore through the masonry element and supporting structure, forming an elongated perforated sleeve having defined axial sections of different perviousness, filling said sleeve with a hardenable thixotropic adhesive mass, and inserting said sleeve within said bore, thereafter inserting within said sleeve a ram, causing said hardenable mass to be extruded from said sleeve, filling selected areas of said bore radially adjacent the spaces within said masonry element and between said masonry element and the supporting structure with selective amounts of adhesive.
