🔩 mechanical anchors: reliable fastening heavy objects to various reasons

In production repairs quite often there are situations when you need to fix on the wall or ceiling of a certain design. Of course, for such a purpose, you can use conventional anchors that are hammered into brick or concrete a hammer or using a gun, but such fasteners would not be sufficiently reliable. The basis of its holding force will be based on only the frictional force, and it is not enough for a solid fixation. Here and come to the aid of mechanical anchors that can hold quite massive and heavy construction.

What is a mechanical anchor

Such a fixing fittings used universally for different surfaces. Mechanical anchor is sawn along the half-sleeve, one side of which is inserted a bolt, and the other nut is screwed onto the thread. After the liner is inserted into the drilled hole, the bolt twist begin with a wrench. A cone back side starts to advance along the thread and push in the sleeve side lobes which arise vraspor hole walls. This ensures reliable fixation of any design on the wall.

In the role of the bolt may be a conventional straight pin with a hook or a ring - here the choice will depend on the needs of the home worker.

How to install the anchorage

Most people faced with similar accessories, but not everyone knows how to anchor fixed to the wall. Let's try to consider this issue in detail.

First we need to make a layout, specifying, where there will be mounting. After that, set in the hammer drill of the desired diameter and drill a hole with a depth equal to the length of the sleeve or a little more.

Very important. If you choose the wrong diameter drill, the sleeve can not get into a hole, or vice versa - will be there to hang out. About any fixture in this case, is already out of the question. The only option in this case is to use chemical anchors, which cost much higher.

When the hole is finished, the dust blown away from the sleeve and inserted with stranded bolt and cone. The ideal is considered to be the diameter of the hole in which the anchor has to drive the light tapping hammer. It now remains to take a wrench and turn the bolt with it as long as possible. How can ensure Dear reader, this work is quite simple.

Dowels, nails and their purpose

Many handyman so called anchor with plastic sleeves. They are intended for fixing cornices, ceiling fixturesHowever their strength enables application even to fix hinged lockers kitchen units. Standard sizes of anchors: length - 4, 6, 8 or 10 cm; diameter - 6, 8 or 10 mm.

Such hardware is even more simplifies installation. After appropriate size is drilled hole, it is inserted into a plastic tube, slotted lengthwise. Next screwed into special nail with thread. And the thread itself is designed so that it can be inside the drive even with a hammer (this greatly speeds up the process), but pull back without screwdriver It will not succeed.

What types of mechanical anchors exist

There are several types of such fittings, each of which has its own area of ​​application. The fact is that, for example, for attaching a heavy chandelier at the ceiling of the hollow core slabs conventional anchors do not. Because then the fixture, hitting into the void partitions, will not be able to fulfill the purpose for which it was intended. This requires a different type of fastener. Consider a little more each.

Wedge and screw mechanical anchor

It is most popular among domestic masters thrust mechanism. When tightening the bolt or nut cone on the end of the stud sleeve decompresses the pitch, resulting in dismantling such fittings becomes possible without damaging the wall. The main objective of using - a clear layout and care when drilling.

Folding anchor spring: what is their feature

This furniture is suitable for hanging chandeliers a hollow core slabs or fixture on dropped ceilings. Such an anchor is inserted into the wide opening and then starts to rotate the stud in the clockwise direction. Inside the cavities disclosed broad petals anchor that does not give him the opportunity to climb back.

Helpful information! Tight fit with the help of this anchor is difficult to achieve, although it is possible, but like him, and is not required. Its mission - to enable the design of suspension.

Frame Connecting fittings

Frame anchors differ from the wedge in that the longitudinal cuts on the sleeve has on both sides. This allows you to tighten the stud bolt so that it was almost flush with the surface. Often used for fixing to the wall wood, Plastic or slotted bricks.

Such hardware is used Handyman quite rare. More it is popular among professionals who install wood or plastic windows, doors, balconies and loggias.

Anchor-hooks and rings: Applications

Here, the mechanism can be quite diverse. The main feature of these anchors is to use as a hook studs or rings. Such accessories are often used when a suspension of anything. Often domestic masters used such as anchor attachment to linen ropes to the loggia.

Important! When fastening children's swings in apartment buildings should be careful. If you fall into the void, the anchor would not hold. But even with normal fixation should not pull the pin. If you cross the tensile strength, long she will keep no and after a short period of time can break off.

Embedded hardware: how they differ

This anchor is installed during the construction phase. It is installed in a certain place of the future surface and then filled with concrete. When the solution dries, the anchor is bricked in. Such a fastener is considered the most reliable and is used for fixing the most heavy structures (channels, beams).

Embedded anchors are rarely used in everyday life. After all, in the construction of a private house owner does not think about where it will be placed or that equipment specifically, to the nearest centimeter. Therefore, the same water-heating boiler is easier to hang after finishing on the wedge or screw anchors. Such fasteners longer useful in the construction industry, where the works are clearly in line with the developed project.

Differences from the chemical mechanical fasteners

If during the preparation of the holes occurred situation where borax were mixed and diameter turned more than is necessary, can be a special two-component, called a purchase in-store chemical anchors. the algorithm next to him.

Of all the dust holes is removed, and then through a special tapered tube into it is injected a certain amount of glue. Now immersed in a conventional anchor hole and wait until the composition solidifies. Time may vary, depending on the brand and manufacturer of chemical anchors. After complete drying of the composition of fasteners can be used without fear of his strength.

To summarize the above,

Without the anchor fixings can not do any repairs. With the help of these screws or nails fasten chandeliers, cornices, TV on the wall or hanging cupboards kitchen units. But despite the reliability of such a fitting, a lot depends on how the work is done. After all, even the most reliable fastener can not stand if its installation is faulty.
