SCREW-IN ANCHOR BOLT AND METHOD FOR INSTALLING CURTAIN WALL AND PANEL THEREWITH
Document Type and Number:
WIPO Patent Application WO/2018/133299
Kind Code:
A1
Abstract:
A screw-in anchor bolt, comprising an anchor bolt sleeve (2) and a position-limiting screw rod (3). A front end of the anchor bolt sleeve (2) is an expandable section that can be expanded by the position-limiting screw rod (3). The position-limiting screw rod (3) can be screwed in from a rear end of the anchor bolt sleeve (2) until the position-limiting screw rod (3) is secured in place. The expandable section of the anchor bolt sleeve (2) is provided with one or more conical surfaces (201, 202). A method for installing a panel with the screw-in anchor bolt comprises: drilling an anchor bolt hole in the back of the panel (1); injecting an adhesive (6) into the anchor bolt hole; placing the anchor bolt sleeve (2) into the anchor bolt hole; and screwing the position-limiting screw rod (3) into the anchor bolt sleeve (2) to expand the anchor bolt sleeve (2). A curtain wall comprises the panel and the screw-in anchor bolt. The screw-in anchor bolt combines mechanical fastening and chemical bonding, improving structural strength and reducing a panel breakage rate.
