Abstract

An expansion type anchor bolt comprises a bolt body, a spacer sleeve, an expandable sleeve, an expansion component and a lantern ring. The lantern ring is arranged between the expandable sleeve and the spacer sleeve and is in the form of an annular body, the bolt is sequentially inserted into the spacer sleeve, the lantern ring and the expandable sleeve, a front end of the bolt is in threaded connection to a cone, then an expansion component is pulled into the expandable sleeve, and the expandable sleeve is expanded in the radial direction. The expansion type anchor bolt is characterized in that the lantern ring is made of two materials different in hardness.

Description

technical field [0001] The present invention relates to a fastener with an expandable sleeve, and more particularly, to an expandable anchor bolt. Background technique [0002] Expansion anchors are fasteners designed for use in masonry base materials that expand to provide retention. This type of expansion anchor is particularly useful in applications where heavy objects must be secured to supports such as concrete. This includes installing heavy applications, etc. Fastening to concrete is unique compared to other fastening applications such as fastening two pieces of metal together by using screws or bolts and nuts. Concrete anchors are more difficult to install and use. [0003] In general, expandable anchors work on the same basic principle—drill a hole of a specific size, insert the anchor, and expand the anchor larger than the hole to make it difficult to pull the anchor out of the hole. Concrete anchors are designed to be inserted into holes in concrete without co...
