Anchor bolt

An anchor bolt is a reliable type of fastening of complex structures

The anchor bolt is one of the most reliable fasteners that has been developed today. Thanks to its design, it can hold objects of considerable weight even in porous building structures. The field of application of anchor bolts is extensive. They are used not only in the construction of concrete structures, but also when performing repair work for fastening in foam and aerated concrete, plasterboard sheets, etc.

Various types of high-strength steel are used for the production of anchor bolts. Production is regulated by GOST 24379-2012. According to the standard, the anchor bolt is a metal rod from 45 to 230 mm with a fastener at the end. Screwing the anchor into the support leads to distortion of the coupling, which secures the bolt in the base. Removing the bolt will cause certain difficulties.

Types of anchor bolts

with a nut - used for fastening in building materials with a dense structure, such as natural stone, concrete, brick, etc.

with a hook - used for fastening objects that need to be periodically removed, for example, chandeliers, lamps, boilers, etc.

with a ring that is used for mounting and hanging various objects. It is used not only for repairs. It can be used when transporting cargo for fastening rope, tension, chain, scaffolding, etc.

two-fold The peculiarity of such bolts is that there are two expandable sleeves at once. In the process of screwing the bolt, one of the bushings enters the second one and decompresses it. Double anchor bolts can be used when working with hollow and porous building materials.

Wedge anchor bolts are more often used in repairs to fasten items. The high price of the product limits the scope of their application. The complexity of the design is provided by the presence of a wedge element inside the sleeve. During the screwing of the bolt, this element presses on the sleeve from the inside, squeezing it.

hammer bolts differ in design from all the previous ones. For fastening, a sleeve is placed in the initially drilled hole, into which a driving element (nail) is driven. After the sleeve is fixed with a nail, a bolt is screwed into it and the object to be fixed is hung on it.

An anchor bolt with a hexagonal head also has a non-standard fastening. To fix the bolt, it is inserted into the hole of the sleeve and twisted, thus expanding the spokes of the spacer sleeve. Slots on the bolt can be made in two ways: for a screwdriver and for a wrench.

What is a chemical anchor bolt

A chemical anchor bolt can be used for fastening to a porous base. The chemical component is an adhesive composition that fills 2/3 of the hole prepared for fastening (before filling with glue, the hole must be well cleaned of remaining crumbs and dust). After the chemical composition hardens a little, an anchor bolt is screwed into it. Fixable objects can be hung after complete solidification of the solution.

Anchor bolts have gained popularity due to ease of installation. To fix the bolt, it is necessary to make only a small hole in the base. But it is necessary to choose the right fastening so that the bolt can withstand the load. Before purchasing, we recommend that you consult with a specialist or contact the managers of the L.E.V.
