Hollow Brick Anchor

Despite the fact that brick has been the most popular building material for a long time, questions may arise during the operation of structures built from it. For example, how to hang various lockers and whatnots on a brick wall, because this problem cannot be solved with a banal nail or dowel? Experts recommend using an anchor for hollow bricks for these purposes. These are quite hardy mounting systems that can hold tens of kilograms of weight. We will describe them in detail in this article.

What is an anchor?

The brickwork anchor is a universal fastener widely used both in the field of capital construction and for performing various simple repair work at home. An anchor has the form of a bolt of a special design, which is placed on the surface of a brick wall.

This fastener is able to withstand various pieces of furniture, lamps, chandeliers, as well as various facades of the hinged type, etc. By the principle of operation, they are similar to dowels. The anchor system also consists of two parts: a spacer sleeve and a support rod. Their main feature is a special notch, which is applied to the side of the surface. This is necessary in order to increase the adhesion of the bolt to the walls of the hole.

Important! Anchors for brick walls, depending on the expected load, are available in different lengths and diameters.

Types of Anchors

Anchor fasteners for hollow bricks are distinguished not only by their size, but also by their technical, constructive characteristics. Based on this, the scope of application of the anchor is also distinguished, which are aimed at solving certain installation problems. In this regard, anchor bolts are divided into several types.

Driving type

This is the simplest type of anchor fastening system. They are used mainly for fasteners on structures constructed from solid brick. Its principle of operation is that an anchor is installed in a previously prepared hole in the wall, after which a special spacer element is activated in it, due to which reliable fixation of all fasteners is ensured. At the end of mounting the main part, a threaded element is screwed into the bolt.

Wedge type

This design of the anchor bolt has a special element that wedges during installation. Actually because of this feature, this fastener got its name. The wedge element, falling into the brickwork, expands and reliably fixes the fastening system on the building structure.

Important! Very often, wedge-type anchor fastening systems are equipped with screws that have a recessed type head.

MSA Products

Their main feature is the presence in their design of a brass sleeve. On its lateral part, longitudinal cuts are made, thanks to which the sleeve is divided into original petals, which expand during installation. And in order for the expansion of the spacer sleeve to be as large as possible, the inner hole in it has a conical shape.

Chemical type

A chemical wall anchor bolt in a brick wall is fixed in a previously prepared hole using special glue.This type is most suitable for use on walls erected from hollow bricks, as well as other porous building materials. This is due to the fact that the adhesive composition that is used with this type of anchor fasteners fills all the internal cavities, thereby reliably fixing the bolt.

Important! Please note that the curing time of the adhesive, depending on the manufacturer, is completely different. Therefore, acquiring this type of fasteners together with glue, carefully read the instructions.

Anchor with a ring

In this case, the ring replaces the standard hex bolt head and is designed for more convenient and easy installation of various objects.

Important! Most manufacturers produce anchor fastening systems with a ring of different sizes. This is due to the fact that the consumer, based on the dimensions and weight of the items fixed with his help, selects a suitable size.

Double Spacer Anchor Products

Their feature is the presence in the design of the spacer sleeve, which is expanded during installation simultaneously in several places. Therefore, it is widely used in the installation of various products on hollow brick structures, since at least one of the spacer elements falls on the solid part, while the rest are in the empty part.

How to install the anchor fasteners in brickwork?

In order for the product to be fixed securely on the brick wall, the installation process of anchor fasteners must be carried out in the following order:

  1. Choose a place where you want to place fixture. Drill a hole equal in diameter to the diameter of the anchor product.
  2. Clean the hole from debris and dust.
  3. Insert into the hole and tighten the bolt.
  4. Tighten the bolt head. Do this until you achieve maximum expansion of the spacer sleeve.

Important! When choosing a place to install fasteners, try to avoid the gap between the bricks, which is filled with cement mortar. The hole must be made exclusively in the brick body itself.

Rules to be followed when installing the anchor

In order for anchor fasteners to be correctly and reliably fixed in a brick wall, it is necessary to adhere to the following rules during operation:

  • The hammer drill is best used exclusively in drilling mode. This is due to the fact that a brick is a rather fragile material, therefore, under the influence of a strong load it can simply crack.
  • Always check the horizontal position of the drill while drilling. If the slightest inclination of the cavity occurs, there is a risk of the fastener itself falling out under the influence of the load.
  • When hammering the support under the anchor, always place a small wooden shelf. This way you will prevent damage to the stud threads.
  • Always check that the surfaces of the sleeve and the shaft are clean.
