Is it worth it to fix something on the nail to the concrete wall? Or are there any better ways of fasteners? These and other questions will be answered this article, which talks about the current test fixtures - anchors, will understand, what is the anchor, and what are the types of anchors. The range of the anchors on the market is represented by an innumerable multitude of different modifications, example:
- bladed anchor KA;
- Drop anchor LAH;
- rod anchor RU;
- AND sterzhneobraznыy anchor;
- RA bolt tie;
- mortgage anchor SORMAT, DRIVE;
- Brass Anchor MSA;
- MTA anchors, KVTM, PFG, OLA, and so on.
When the finishing, repairs, or construction work to do without fastening devices impossible. These may be screws or nails, ie devices, which themselves directly, without any additional components capable of bonding materials and withstand the corresponding load. They can be applied to the sheets of drywall, wood, or thin elements, made of metal, fixing, which occurs between the simple fasteners and the base, enough to effectively consolidate and perception, relating to the design, loads.
However, if the base is made of stone, concrete or brick and has a large (as compared with light materials) hardness, the use of such attachment can not solve the problem arising. For, to verify this, simply try to hammer a nail into a wall of concrete, and immediately become clear to the validity of this statement.
The anchor is translated from the German language, as an "anchor", and this name fully explain the principle of its operation. The fixing member is fastened to the main array is not directly, and using dowels or anchors, and which are designed to ensure, to display the desired clutch torque.
The conclusion is: extremely difficult to draw a distinction between specific Fixing Technology.
We have formed such an opinion, dowels or anchor that is part, that any (chemical or mechanical) method improves the bond between the primary product, which is to be attached and the base. To level, wherein the data elements are able to transfer a load placed on them. Generally, dowel is lighter species anchor.
The main types of anchors
The field of application of anchors during construction is mounting heavy structures. In carrying out repairs in the apartment anchoring mainly used when fixing window and door frames, when attaching suspended ceilings, and also during the installation of chandeliers and lamps. Now it is clear, what anchor. Proceed to the types and locations of application examples with photos.
Drop-in anchor made of brass, steel
Drop-in anchor LA, LAH. This is the easiest type of anchoring, having internal threads. Used for mounting in stone, brick or concrete structures. Inserted in advance into a bore of the desired diameter and depth. The opening for this type of anchors (as for all other) should first clean. After that, as the anchor is inserted into the opening, he has a special device expands, wherewith achieved the desired degree of adhesion. In the wake of this anchor is screwed into suitable threaded fastening element. The same applies to this type of anchor MTA, which is used for substrates having internal cavity.
Wedge anchors with a nut
Wedge anchors KA. They are manufactured using different technologies and are elektrotsinkovannymi KA, acid-KAH, Hot dip galvanized and KAK. Equipped with a special blade, which expands during assembly and is secured in the bore. Lets make a through fastener mounted through the base material. Inserted into the prepared hole, hammered with a hammer and tighten the usual key. By products of this type include screw anchors RAR-rustproof, or RA-elektrotsinkovanny. These types of anchors are equipped with recessed screw head. This enables their use in fastening of door and window frames. In the process of tightening the screw anchor blade is securely fastened to the fastening hole.
Rod clamp RU operate on the principle of the wedge anchor, It is made to install a few tiles and insulating layers. An additional quality of such products is the ability to make its installation at a slight angle to the surface. Method fixation nest expanding wedge is also used in the construction of the anchor rod TA. This product, equipped with an internal thread, complete with rod, which optionally can be cut, to bring it to the required length, It can be used for the attachment of multiple layers of materials. After driving in the anchor fastening hole, lockable element is fixed on the rod with washer and nut.
PFG anchors are equipped with an internal thread, and in expanding and fixed efficiently in the nest during the twisting them insert details. Anchor PFG can be used in conjunction with the bolt plugs into IR, a bolt with a hook head AK, conical screw VR, bolt equipped with loop or SR insert sleeve having IHH, THEM. This anchoring is used for work with solid bases.
Brass Anchor MSA
Constructive basis for this type of anchor is concrete, stone or brick. Brass sleeve of the anchor MSA fitted with an internal cavity, having a conical shape (threaded), which gradually tapers to a tip. With this restriction, during tightening of the screw sleeve expands and firmly fixed by its not smooth walls inside the mounting hole, Based on the work done in.
