Arrangement for and a method of anchoring a mounting element in a hole of masonry and the like

In an arrangement for anchoring a mounting element in a hole of a masonry or other structure by the use of a binding material, a combination comprising a sleeve-shaped mounting element having a cross-sectional dimension less than the cross-section of said hole so as to form a circumferential recess between an outer surface of said mounting element and said hole, said mounting element having a central axial bore adapted to receive therein a threaded element and the like and being provided with at least one substantially transverse bore communicating said central bore with said circumferential recess;

• ribs provided on a trailing end portion of said mounting element and projecting therefrom for holding the mounting element in a predetermined position relative to said hole, said ribs extending in an axial direction and being circumferentially spaced from one another, said ribs being bevelled towards a leading end of said mounting element and having a maximum transverse dimension exceeding said cross-section of said hole;
• a flange member provided on said trailing end portion of said mounting element and transversely projecting from the latter, said flange member having a transverse dimension exceeding said cross-section of said hole so as to backwardly close the same and to thereby prevent backflow of binding material out of said hole;
• and an adapter element tightly inserted in said central bore of said mounting element and having a blind hole communicating with a source of said binding material, and said blind hole including a transverse hole portion communicating with said transverse bore of said mounting element so as to establish a path for passage therethrough of said binding material from said source into said circumferential recess to thereby anchor said mounting element in said hole.

A method of anchoring a sleeve-shaped mounting element in a hole of a masonry or other structure, comprising the steps of inserting in said hole a mounting element of a cross-sectional dimension less than the cross-section of said hole so as to form a circumferential recess between said mounting element and said hole, said mounting element having a central bore and being provided with a transverse bore communicating said central bore with said recess;

• holding said mounting element in a predetermined position relative to said hole;
• closing said hole so as to prevent backflow of binding material out of said hole;
• tightly inserting an adapter element into said central bore of said mounting element, said adapter element having a blind hole adapted to communicate with a source of said binding material, and said blind hole including a transverse hole portion communicating with said transverse bore of said mounting element;
• communicating said transverse hole portion of said adapter element with said transverse bore of said mounting element;
• feeding said binding material into said blind hole of said adapter element so that said binding material travels from said transverse hole portion of said blind hole through said transverse bore and into said circumferential recess to fill the same and anchors said mounting element in said hole;
• and extracting said adapter element from said central bore of said mounting element.
