Anchors for concrete - not the only way of fastening

anchors for concrete - fasten

unreliable design, this type of attachment is used in cases when it is necessary not only to secure some material to concrete, but also securely hold it in such a position that no effects could not affect the force of attachment.It is usually combined with tough and heavy base any lightweight construction which is easy to tear, such as drywall or wood.

There are anchors of several types of material: metal, nylon and plastic.Mounting method they also can be different: chemical and mechanical .Chemical akin to glue and mechanical needs no special presentation.That is based on the chemistry withstand much greater loads and is not afraid of moisture.

In turn chemical anchor for concrete divided on the principle of mixing in ampoule and injected .The first represented in the form of a glass ampoule, which has two compartments containing the desired components.This construction is inserted directly into the concrete (in a hole drilled specifically Wizard) and it is divided to drive rod.Inject anchor looks like a syringe, in which there is a one-component composition or a two-component, which is mixed with pressure piston towards the outlet.

Mechanical anchor is also not the only one, there are persistent, and there are those who are driven and held by friction.By way of securing their share in spacer , Drop , spring and universal .

Screws for concrete or peg - mount window frames and door frames

This hardware can often targeted application in areas where other types of attachment can not be applied because of the complexity of the installation or the fragility of the structure. Screws for concrete is often used where the window frame, for example, is practically at the edge of the escarpment.Then the situation is ambiguous, if you use other fasteners, the need to place a dowel, in this case, you can break off a piece of the wall.A tiny screws will be an alternative, and quite reliable.

They are used without anchors, attached directly to the wall through the profile, and sometimes may require pre-drilling.In this case, to secure the well-scrub dust hole.You can put on the screw adhesive to be sure.If the drill hole is still necessary, in any case do not use a hammer, shock vibrations destroy the foundation of what we have tried to avoid.Such screw on concrete lining "for centuries", so unscrew it extremely difficult, sometimes impossible, so proceed deliberately.

Dowel Concrete - solid foundation

dowel concrete is used as a mounting base for some of the screws and anchors.The quality of the material depends on the reliability of your mount, so some of them are also split by type.The criterion serves the concrete hardness, it is heavy, light (porous materials).They are characterized by resistance to compression: from heavy, this figure is high, in light - low, so it can not long withstand the pressure.

dowel action is based on its wedging.Antennae on his body directed against the backstop, so after it was inserted into the wall to get it almost impossible (only violating the integrity of the hole).

final "dead" fixation occurs when the plug comes in a screw, then there is wedging, which together with these mustaches will not get out will never mount.

Material dowels depends on the application, but rather, on the weight of the object, which will be held on the screws.If this is something easy, such as furniture, then fit the plastic plug, and there is a heavy metal for construction.For lightweight concrete anchors made of steel, they are made in the form of "Christmas trees", the operating principle is the same.
