What is fastening brick partitions to walls, how is it done and what rules must be followed when attaching?

Brick partitions must be attached to walls when building or remodeling a space in order to maintain structural stability and integrity. This procedure entails firmly attaching brick walls or partitions to a building’s preexisting floors, ceilings, and walls. In addition to extending the structure’s lifespan, proper fastening is essential for preserving its functionality and safety.

Brick partition fastening normally calls for meticulous planning and adherence to precise specifications. The technique selected is determined by a number of variables, including the kind of wall materials, the load-bearing capacity, and the surrounding conditions of the structure. Adherence to building codes and regulations is imperative in order to guarantee that the installation satisfies safety requirements and durability expectations.

Brick partitions are frequently fastened together using mechanical fasteners like screws or anchor bolts. These offer a sturdy, dependable connection and are drilled into the current wall material. In order for these fasteners to effectively support the weight and pressure applied by the brick partition, their depth and spacing are crucial.

When may it be required?

Brick wall tying is utilized in the following situations:

• To create an adjacent brick partition. An interior partition inside the building is attached to the existing load-bearing wall. Other possible options: the walls are connected on the outside to form a balcony, terrace, porch.
• Connection of facing brick and load-bearing wall. They create such a structure immediately, if the budget allows, or a little later; there are several ways to connect. The essence of the process: an additional layer of facing brick is laid on top of the rough brick, which makes up the finished building.

What does the term nodes mean and what are they for??

Brick wall knots serve as connecting points between the structural components of a building that have different loads applied to and transmitted from the base.

When the walls are properly mated, the building’s weight is distributed evenly and the walls’ structural integrity is preserved. Here, forces are redirected to structural components, making this a crucial structural section of the building.

How they are formed?

Brick structures with nodal connections are made rigidly of bricks connecting elements to one another; a specific kind of masonry is used to form the angle. For instance, a partition appears to "grow" out of a load-bearing wall that is constructed concurrently with it.

step-by-step instruction:

1. A mortar 8 mm thick is laid out, and a brick in the order: 2 whole ones with a poke on the outside, 2 ¾ bricks. The pokes should form the outer edge.
2. 2 bricks are installed with pokes to those that are ¾ in size.
3. 2 bricks are laid with a spoon to pairs of full-size. Part of the first row of the main wall is ready.
4. Add 2 full-size ones to the adjacent row where the ¾ bricks are installed.
5. All seams are thoroughly coated with a solution.
6. Making the second row. A thin layer of mortar 8 mm, ½ of the first brick and ½ of the second, the second row is placed with a spoon on the front side, then alternately.
7. Next, full-size bricks are stacked with pokes on the inside of the main wall.
8. On the adjacent wall, a full-size brick is laid across the previous row. All seams are well clogged, size up to 1 cm.
9. Then the order is repeated according to the diagram.

The video’s diagram and instructions:

Although nodes can form in any order, the technology will differ slightly. Depending on the ambient temperature, brick has varying sizes. Seasons and humidity have an impact on its physical characteristics as well; the wall can move 2-3 cm in either direction.

In order to prevent cracks and damage, consideration must be given to the material’s physical characteristics when constructing flexible brick wall units.

Rules for tying load-bearing brick partitions to axes

The primary walls, which include load-bearing and self-supporting walls, are located according to the coordinate axis and are marked in the documentation prior to construction commencing. These axes are also referred to as alignment axes, and they are identified on a building site by markings.

Expert surveyors are tasked with delineating and segmenting the area. After placing benchmarks at predetermined locations, construction work (digging a trench or hole for the foundation, etc.) can start.

A bundle of paperwork is gathered prior to construction work commencing. A project of the surveyor’s work that includes an axes breakdown is one of the things among others.

Its objectives are to transfer design solutions from the drawings to the construction site and to install marks to fix coordinate points in space. Until construction is finished, all markings must be kept in place; if any of them unintentionally wander, they must be put back in place.

The Unified Modular System (EMC) states that coordinate axes must be spaced apart by a multiple of M. It is known as the main building module and has a measurement of 100 mm.

Intended to bring building structures together. For greater convenience during large-scale construction, a 3M indicator measuring 300 mm is available as an option.

Building structures are positioned in relation to the coordinate axes by means of reference. The coordinate axes and the floor’s side lines are always in alignment. As a result, the binding establishes the space between the floor slabs and the walls.

The binding takes place:

• Zero. The coordinate axis in the drawing coincides with the line of the internal plane of the wall.
• Central. The geometric axis (line passing through the middle of the wall thickness) coincides with the alignment.
• Construction. For brick structures, the center shifts. For example, the wall thickness is 38 cm, the inner edge is attached to the axis at a distance of 13 cm, to the outer edge at a distance of 25 cm.

As per the guidelines for connecting the primary structural components (described in GOST 28984-91) to the coordinate axes:

• The inner side of load-bearing external walls shifts relative to the alignment axis towards the depth of the building. The distance by which it can move is equal to ½ the thickness of the load-bearing wall inside the building. Alternatively: in proportion to module M or half of it.
• The geometric axis of the load-bearing walls inside the building coincides with the alignment axes. The rules for internal load-bearing walls do not apply if they belong to a staircase structure or contain ventilation ducts. In this case, deviations are allowed.
• Combination: floor slabs resting on brick walls. The inner sides move 13 cm relative to the longitudinal alignment axis.
• Brick walls 38 cm or more and longitudinal ceilings (beams). The alignment axis runs 25 cm from the inside of the wall.
• Walls 38 cm are paired with pilasters 13 cm. The distance between the centering axis and the inner edge is 13 cm.
• Zero alignment rule: if the thickness of a brick wall with pilasters is up to 13 cm, the inner edge is aligned with the axis.

Why these regulations were put in place:

• the load on load-bearing structural elements must be uniform to avoid overload and destruction of the walls;
• drawing coordinate axes helps builders and designers interact with each other, implement the idea of ​​construction strictly according to the planned plan;
• load-bearing walls and partitions create a single symmetrical composition, possibly with the addition of creative elements that do not affect the durability and strength of the building.

How to tie to existing brick walls?

Brickwork can be connected to a finished wall in a number of ways. They are used for attaching cladding to a rough wall and installing partitions to load-bearing structures.

Fundamental Guidelines:

• A lighter structure must have a stable foundation, be installed on the floor or be a continuation of the base. In this case, the base under the finished wall and under the new one should not be connected, since different shrinkage will occur. The foundation of the partition may consist of a different material, but must be on the same level as the foundation of the load-bearing wall.
• The binding should cause minimal harm to the existing wall, otherwise there is a risk of compromising the thermal insulation properties.
• Follow the technology so as not to damage the finished building, save it from cracks.

It is advised to tie using bricks of the same size so that the materials are easier to connect and the order is consistent.

The process must be followed because, while finishing work is being done, pressure is applied to the partitions from both the sides and the ceiling. Binding prevents deformation and collapse.

Materials and tools

The following supplies can be used to join brick walls together:

• Galvanized steel strips. Advantages: affordable price, always in stock. Disadvantages: increases heat loss through the walls. A 6-8 cm ceiling anchor is used with them.
• Basalt connection. Pros: does not allow cold to pass through, is considered the best option for such work (there is a certificate). Cons: expensive, sold only in specialized stores.
• Fiberglass reinforcement. Pros: low price, no corrosion, easy to buy, reinforcement with whole whips, does not release heat, ease of use, reliability. Dowels are used with it.

Steel strips work well for cladding without insulation and fiberglass reinforcement or basalt bonding for walls with insulation. A hammer drill and a drill bit that matches the size of the materials you’re using are also required.

Step-by-step procedure for linking

The two techniques listed below can be used for facing masonry as well as for tying the partition.

Without insulation

The building of the structure needs to happen in this order:

1. We take into account the distance between the rough wall and the facing wall. If it is more than 5 cm, it is better not to skimp and use the entire metal strip (20-30 cm long). Material costs also depend on the size of the facing brick. If the distance is 1-2 cm, then the strip is cut into 2 equal parts. Bend it in an L-shape so that the angle falls on the junction of the walls, the side with perforation should lie on the facing brick and take up about half.
2. Using a hammer drill, create holes approximately 6 cm deep, suitable for anchors in increments of 1.5 bricks. Rough brick does not always have a dense texture. It is necessary that the anchor is held tightly in the hole. If the brick crumbles when drilling, you need a new hole nearby so that the structure does not subsequently get torn out of it during the shrinkage of the walls.
3. Insert the anchor into the special hole on the smaller part of the bent metal strip. Install the element into the wall perforation and carefully drive the anchor until it opens.
4. After all the elements have taken their place, lay out the mortar and continue laying. The metal plate should remain in the seam, where, thanks to the perforation, it will fit tightly and hold the facing wall.

With insulation

The second choice, provided that wall voids are filled with insulation. For installation inside the load-bearing wall, we use glass-plastic reinforcement that is cut into pieces 25–30 cm long at a rate of 6-7 cm. We also use insulation that is 10 cm thick, spaced 1-2 cm from the facing wall, and comprise ¾ of the facing brick’s thickness.

Phases:

1. Drill holes through the insulation and deep into the carrier wall by 6-7 cm. It is recommended to make holes for reinforcement as close as possible in height to the level of ribs of facing brick. The pin should lie on it, and not hang in the air.
2. Insert the reinforcement with dowel at the end into the hole, drive a hammer.
3. Repeat the operation after 1-2 bricks.
4. Put a new row of cladding so that the reinforcement is inside the seam. Fiberglass is quite flexible, if necessary, it can be slightly bended.

After 3–4 rows, repeat the mount.

In the event that facing bricks are used initially and black masonry is formed afterwards, reinforcing mesh measuring 10 by 10 cm can be placed every four rows in the cladding seams (the size of the pieces depends on the thickness of the brick and the space between the walls). Even Should the draft and finishing bricks differ in size, you can adjust the seams to achieve the desired height, and the mesh will lay flat.

On the other hand, flexible connections such as perforated steel strips or thin reinforcement can be installed ahead of time if you first build rough masonry and then cover it with facing bricks. The connection can be adjusted to fit the seam if the rough bricks and facing are different sizes.

Using a mesh when first creating rough masonry is not advised. It doesn’t bend well, and the brick will be under a lot of pressure if the seams don’t match. The cladding wall will fracture with time.

Difficulty connecting

The structure and arrangement of attractive brick wall units worry inexperienced masons. With the accompanying video and the given instructions, you can learn the process.

To establish trustworthy relationships It is advised to only use premium materials; specifically, the solution needs to be able to firmly grasp and hold the elements.

If you are having trouble tightening a dowel or anchor, try changing the component or making a new hole.

Flexible connections are preferred because they can be reshaped in 99 percent of cases in case the row layout is not aligned.

Possible errors

Things to be mindful of:

• Reinforcement mesh for connection is used only if the cladding is created first.
• When connecting a partition and a finished load-bearing wall, it is recommended to install flexible connections. The load on these elements is different and over time, a rigid connection will violate the integrity of the walls.
• It is recommended to connect the load-bearing and load-bearing walls or a partition with a partition rigidly, for reliability.
• The foundation of the walls should be at the same level, a tight connection is maintained even during shrinkage, and the overall picture is not destroyed.

For brick partitions to have structural integrity and longevity, proper fastening is essential when attaching them to walls. Using the proper anchors or fasteners to firmly attach the bricks to the existing wall is the usual attachment method. Particularly in settings where the ability to support weight is crucial, this procedure guarantees stability and safety.

It’s crucial to adhere to certain norms and regulations when the attachment process is underway. First and foremost, knowing the load requirements is essential as it dictates the kind and size of fasteners required. To increase the efficiency of the fastening process, make sure the wall surface is clean and ready before attaching.

Furthermore, the choice of materials and fastening methods can be influenced by factors such as thermal expansion and moisture resistance. Contractors and homeowners alike can contribute to the overall durability and safety of the structure by following these procedures, which guarantee that brick partitions are firmly attached.

In the construction industry, brick partitions must be fastened to existing walls precisely and in accordance with prescribed guidelines to guarantee safety and structural integrity. This article examines the fundamental techniques for firmly fastening brick partitions to walls and provides a step-by-step explanation of the procedure. Every step is essential to creating a strong connection, from choosing the right anchors and fasteners to making sure that everything is spaced and aligned correctly. Building professionals can successfully incorporate brick partitions into a variety of architectural settings while preserving stability and durability by being aware of these protocols and adhering to suggested practices.
