DEPLOYMENT-TYPE SLEEVE, ANCHOR BOLT, AND SET ANCHOR
Document Type and Number:
WIPO Patent Application WO/2022/265424
Kind Code:
A1
Abstract:
The present invention provides a deployment-type sleeve, an anchor bolt, and a set anchor, wherein the deployment-type sleeve is formed to have, without using a pipe-shaped tool, concavo-convex protrusions formed on the inner wall and surrounding the anchor bolt so as to be deployed toward a concrete structure by a pressing head of the anchor bolt and is embedded and fixed in the side surface of an installation hole of the concrete structure due to the external force or nut fastening. The deployment-type sleeve includes an inner wall and an outer wall having the length and the outer diameter corresponding to the depth and the diameter of the installation hole perforated in the concrete structure. The concavo-convex protrusions are formed on the inner wall in the lengthwise direction of the anchor bolt and surround the anchor bolt, and thus, the deployment-type sleeve is deployed toward the concrete structure due to the pressing head of the anchor bolt and then is embedded and fixed in the side surface of the installation hole due to the external force or the nut fastening.
