Little about the anchors

To beat or not to beat? In terms of whether or not to hammer a nail into the concrete wall? And if there are any more effective ways of fixing? Answers to these questions gives the proposed article, which talks about today's mounting products - the anchor. There are so many anchors, such as: Drop-in anchor LAH, screw anchor RA, wedge anchor KA, rod anchor TA mortgage anchor SORMAT, anchors, AIT, PFG, kWm, OLA, DRIVA, brass anchor MSA, rod holder RU and so on., Etc. ., etc.. The manufacture of construction, finishing and repair work can not do without fasteners. This may be nails or screws, that is, products that are directly themselves, without additional devices are capable of bonding material and carry the proper load. Applied to wood, drywall sheets or thin metal components, clutch, arising between such simple fasteners and material, enough for a secure fit and the perception of structural loads. However, if the base is made of concrete, stone or brick, and has more than a light construction material hardness, the use of such fasteners can not solve the arising problems. Enough to try to hammer a nail into the concrete to verify this assertion. Anker, translated from German means "anchor" and the name explains the principle of his actions. Fastener is mated with an array of reasons not directly but through the anchor or anchors, which create the desired moment of the clutch. Strictly speaking, it is difficult to draw a clear distinction between the anchor and dowel. In our opinion, the anchor or dowel is the element that a certain (mechanical or chemical) way improves the adhesion between the primary fasteners and ground to a desired level. In fact, the plug is lighter kind of anchor. Scope of the anchors in the construction - mounting Responsible heavy structures. The apartment anchors are used mainly for installation of window and door frames, under the ceiling, as well as for the installation of chandeliers. Drop-in anchor steel anchor LA, LAH. This is the simplest type of anchor with internal thread. Suitable for installation in concrete, stone or brick construction. Mounted in a pre-drilled hole required depth and diameter. The hole for this type of anchor (as, indeed, for all others) must be pre-cleaned. After installing the anchor into the hole using a special device decompressed, thus achieving a reliable degree of fixation. After that, the anchor is screwed into the corresponding groove on the fastener. The same type is the multi-anchor MTA, used to reason with internal cavities. Wedge Anchors Wedge Anchors KA. Produced elektrotsinkovannym KA, KAK Hot dip galvanized and acid-KAH. Equipped with a special wedge, which is in the process of installing extended and locked into place. Allows cross-cutting assembly mounted on a base material. Placed in the prepared hole, hammered with a hammer and tightened with a spanner. By products of this type may include screw anchors RA - elektrotsinkovanny, or RAR - stainless. These anchors are fitted with screw utaplivaemoy head, which allows their use during installation of window and door frames. As you twist the screw wedge anchor is firmly fixed in the hole. Rod clips Rod retainer RU, acting on the principle of the V-anchor, is designed for advanced setup in a few successive layers of cladding and insulation. An additional advantage of such a product - the ability to produce its installation angle. Pinning mechanism in the nest with an expanding wedge is also used in rod anchor TA. A similar piece with internal thread, in combination with the rod, if needed, are cut to required length, can be used for installation of multiple layers of material. Once the anchor is hammered into the hole and secured the material is fixed on the rod with nuts and washers. Anchors Anchors PFG PFG have an internal thread and in the process of screwing in the plug-in elements are extended and securely fastened in place. PFG anchor can be used in conjunction with a tapered bolt VR, propelling bolt IR, Hook head bolt with AK, a bolt with a loop or SR with inserted sleeves IH, IHH. Used for solid reasons. Brass Anchor Brass Anchor MSA MSA. Constructive framework for this anchor - concrete or brick. Brass sleeve anchor MSA has an internal cavity of conical shape (thread), which narrows to the tip. Due to this, as far as tightening the screw sleeve is distributed in the wide and tightly pressed against its rough walls to the inner surface of the hole in the ground.
