When carrying out repair, finishing orConstruction works, practically, it is impossible to do without anchors. The production of anchors uses steel with a high class of strength, which provides a very reliable fixation in brick and concrete.
There are several types of anchors, differing in shape, size and application.
You will need
- Anchor, drill or punch, winning drills, hammer
Choose the type of anchor, depending on the type of work to be performed
Anchors are used for the installation of equipment andSheer, heavyweight structures to natural stone, full bricks or concrete. Any anchor consists of three parts - a stud or bolt with a thread, a sleeve and a spacer element called a collet. When tightening the anchor, the collet, thanks to the welded bushing, moves up the thread and expands the sleeve. The liner rests against a concrete or stone surface and is firmly fixed there due to friction, stop and embedment.
All the anchors can, conditionally, be divided into several types.
The pile anchor is the simplest kind of anchor. It is a hollow bush with an internal metric thread, into which the fastener part is screwed. In the inner part of the anchor is embedded a steel cylinder, which provides wedging during installation.
Wedge anchor. The special wedge of this anchor expands during installation and is securely fixed in the socket. The wedge anchor allows for through installation and does not require precise drilling depth for its installation.
Anchor with spacer sleeve. This anchor is a rod, ending with a thread and a cone, with a washer, hexagon nut and two movable, cylindrical couplings. Used for the installation of cable trays, consoles and other structures.
Anchor plate is a very flexible fastening, especially popular when installing window structures. Anchor plate well withstand loads in the perpendicular plane of the window.
Drill a hole in the surface with an electric drill or perforator with a winning drill. The diameter of the hole must match the outside diameter of the anchor.
Gently clean the hole from dust.
Insert the anchor, slightly wedging the sleeve.
Hammer the anchor with light hammer strokes. Ideal is the installation, in which the anchor sleeve is buried flush or level with a concrete or stone surface.
Tighten the nut.
