SCREW ANCHORS FOR USE IN MASONRY |
摘要 |
A threaded fastener designed for anchoring imbedment into masonry structures and more particularly into masonry structures which include relatively hard aggregate. A critical distinct relationship between parameters of a fastening system such as the lead angle of the thread, the included angle of the thread, the depth of imbedment of the crest of the thread in a bore of predetermined diameter exists in order to create an adequate effective fastening system for hard aggregate masonry or concrete. |
