What is an anchor of the sleeve?
The sleeve anchor is the type of fastening element used to secure objects to the structure of concrete or masonry. They can be used to connect to two or more concrete structures or to fix an object such as shelves on a brick wall. In some areas, the sleeve anchors also indicate two -stage screws or anchor screws.
The sleeve anchor consists of a fixed metal screw or pin with a conical tip that secretes on the sides. The metal sleeve is wrapped around the outer side of the pin, allowing the tip of the pin to expand the end of the sleeve. The pad and the nut sit on the top of the set and installation screw. Once the sleeve anchor is inserted into the concrete, the installation programs turn the nut and pull the pin into the sleeve. When the widespread end of the pin passes into the sleeve, it causes the sleeve to spread out and store concrete for safe holding.
The anchor installation of the sleeve consists of an adventure process. FirstE must drill the installation program into the concrete using a hammer. The opening should have the same diameter as the screw, but is often slightly longer than the screw to allow proper installation. The installation program then uses a wire brush and vacuum to remove all concrete or masonry residues from the hole to ensure that the screw is fitted correctly. Any fragments that remained in the hole could endanger the anchor's sleeve ability to grasp concrete or bricks.
The installation program then stores the anchor in the hole and tightens it with the key. Depending on the manufacturer, the anchor bolt may require a specified number or rotation to ensure that it has been fully extended. In some heavy applications, manufacturers recommend using a torque key to use a specified amount of force when installing.
The anchor screws must be selected carefully based on the status of the concrete and the weight of the object. Old or damaged concrete or brick requires a heavier or locot of nger sleeves than a new, well -built concrete structure. The harder the je The object that attaches the anchor to the anchor bolt will have to be to offer the appropriate support. Installers must also explain vibrations or external forces that can be applied to the screw. When the anchor screws are used outdoors or near corrosive chemicals, they should be galvanized to prevent rust or corrosion.
