Creating jumpers with BAUT stirrups

When creating building projects, special importance is attached to window and door openings. The easiest way to emphasize them is to highlight the jumper using brickwork, the execution of which can be completely different.

BAUT clamps for all types of masonry

To create such jumpers, there are BAUT Clamps that can be used for any type of masonry.

So, BAUT SK 50-40 clamps are used in the simplest form - horizontal masonry. Such clamps lead into vertical seams in the first row of masonry. It should be noted that this type of lintels should consist of at least 3 rows of masonry. Typically, to strengthen the rows, reinforcement between the first / second and second / third rows of masonry is mandatory. For the aesthetic completeness of the lintel, a prerequisite is that the first row should consist of solid bricks.

For vertical masonry, it is customary to use BAUT SK 50-170 and BAUT SU 50-45 clamps. the use of 2 types of clamps is justified by the fact that the vertical masonry, like the horizontal one, consists of at least 3 rows of bricks. However, if their first row is stacked vertically, then the second and third - horizontally. But the option is also possible when the first 2 are vertical, the 3rd is horizontal. So, BAUT SK 50-170 masonry accessories are used in the first vertical row, and BAUT SU 50-45 - in the second horizontal row. They fit into every second vertical seam.

The technology of laying the lintel on the edge inward differs from vertical masonry, only in that its execution must be done at a right angle to the facade. It is characteristic that the installation order is almost identical. The only difference is that you need to use other clamps - KK 50-65. For these collars, the possibility of their movement to the desired depth is characteristic.

Under the combined masonry, understand the use of alternating two halves and 1 full brick. Such a jumper always begins and ends with vertical masonry. To create such jumpers, BAUT SKK 50-170 or SKK 50-270 clamps are used.

In addition, a common type of combined masonry is one and a half bricks. This type of masonry is able to give the lining a special solemnity and volume.

It should be noted that the use of BAUT clamps, as well as the flexible connections described above, contribute to an increase in the strength of the masonry, and also prevent the appearance of delaminations and cracks on the facade, due to the uniform distribution of loads on each individual brick.

Murfor reinforcement is a welded structure 3 meters long, consisting of 2 parallel metal bars connected to each other by a curved third bar.

The purpose of Murfor reinforcement is to increase the strength of the masonry, especially in case of uneven loads.

Murfor fittings open up new architectural possibilities:

• unbandaged masonry;
• brick lintels;
• the ability to exclude a reinforced concrete belt under the roof;
• increasing the distance between expansion joints (or completely eliminating them);
• preventing the occurrence of cracks;
• preventing masonry delamination and / or destruction due to excessive loads, subsidence of the foundation under the influence of various natural and human factors.

Murfor fittings are easy installation, as well as the quality of the products, the module corresponding to the brick.

Application:
A solution is applied over the masonry. Reinforcement is pressed into the mortar (at a distance of at least 20 mm deep from the edges of the masonry), then covered again with mortar. The solution will level out. The next row of masonry is laid out.
When erecting masonry on an unstable base, for example, on floor panels, it is necessary to reinforce the first 4-5 rows of masonry.
The extension of the reinforcement along the length of the masonry is carried out so that the ends of the reinforcement are parallel in the solution, and not one above the other, with a run of at least 200-250 mm.

Solutions to common problems:

1. Situation: the soil under the building under construction is weak or with different physical properties.
Result: there is a danger of uneven settlement of the foundation and, as a result, cracks may appear on the facade wall.
Solution: the first 5 rows of masonry along the entire perimeter of the building are reinforced with Murfor reinforcement. Then it is recommended to reinforce the masonry every 400 ... 600 mm. in height.

2. Situation: masonry of different heights.
Result: local stresses arise in places of height difference.
Solution: Murfor rebars take over the loads and distribute them over a large area of ​​the wall.

3. Situation: the need for the construction of formwork and concreting.
Result: the presence of "cold bridges", installation is time consuming.
Solution: the traditional reinforced concrete belt can be replaced with a reinforced stone belt. Such a belt consists of 4 rows of masonry reinforced with Murfor, or 2 rows of masonry and 2 Murfor reinforcements in each row.

Specifications:

Tensile strength: min. 550 N/mm2
Yield strength: min. 500 N/mm2
Shear strength of welded joint: min. 2500 N
Thickness of a layer of a zinc covering: 70 gr./sq.m.

Reinforcement Murfor RND / Z is of the following types:

The horizontal brick lintel is one of the easiest laying methods. It is a direct continuation of the facade masonry. Most often it is used in industrial and multi-storey buildings or when window and door openings should not be allocated .

It is important to note that when performing work on installation of a horizontal brick lintel should only be used solid brick (otherwise there will be “leaky” bricks above the opening, which is not at all beautiful). This moment should be taken into account at the stage of placing an order for the material, since in most cases facing ceramic bricks are supplied hollow.

The jumper consists of at least of three horizontal rows of solid facing ceramic bricks on traditional masonry mortar. Clamps are inserted into each vertical seam of the first row. In the horizontal seams between the first and second, second and third rows of masonry along the entire length of the lintel and beyond it on both sides, Murfor RND / Z-50 reinforcement is located.

In this way, a brick jumper up to 2 meters is mounted in the manner described above. If your opening is more than 2 meters, the design must be supplemented with hinged brackets.

To achieve the nominal strength, it is recommended moisten the masonry up to 2 weeks depending on climatic conditions. This recommendation is especially recommended for sand-lime bricks and bricks with a high water absorption coefficient.

You will need the following items for mounting a horizontal brick lintel:

Installation of a horizontal brick lintel up to 2 meters:

Formwork construction Bring the facing masonry to the level of the lintel and build the formwork on which the first row of bricks will be laid	Installation of the first row Clamps SK 50-40 are located in each vertical seam of the first row of masonry, i.e. 1 clamp for each brick.
Insertion of MURFOR fittings Murfor RND/Z-50 fittings are inserted into the corresponding grooves on the clamps. The reinforcement should extend beyond the edges of the opening by at least 250 mm in both directions.	Mounting clamps SU 50-45 In the second row of masonry, in every second vertical joint, place clamps SU 50-45
Murfor RND/Z-50 fittings are also located in the second row of masonry. In both rows (both in the first and in the second), the reinforcement must extend beyond the edges of the opening by at least 250 mm in both directions. Further, every 300-500 mm along the height of the masonry, Murfor RND / Z-50 reinforcement should be placed to achieve uniform load on the lintel.

Installation of a horizontal brick lintel over 2 meters (using suspension brackets):

Installation of formwork and the first row of brick lintels Bring the facing masonry to the level of the lintel and build the formwork on which the first row of bricks will be laid. Place SK 50-40 clamps in each vertical joint of the first row of masonry, i.e. 1 clamp for each brick.	Installation of fittings MURFOR RND/Z-50 MURFOR RND/Z-50 fittings are inserted into the corresponding grooves on the SK 50-40 clamps; in this case, it is first necessary to insert the bottom plate of the hinged bracket into it.
Hanging bracket attachment The bracket is directly fixed on the bottom plate under the reinforcement of the first row and to the wall.	Mounting clamps SU 50-45 In the second row of masonry, place SU 50-45 clamps in every second vertical joint.
MURFOR rebar in the following rows Reinforcing bars are located in the second and third rows of masonry. In both rows (both in the first and in the second), the reinforcement must extend beyond the edges of the opening by at least 250 mm in both directions. Further, every 300-500 mm along the height of the masonry, Murfor RND / Z-50 reinforcement should be placed to achieve uniform load on the lintel.	Humidification of masonry and dismantling of formwork Within 2 weeks, the masonry should be moistened (this is primarily important for facing bricks with a high water absorption coefficient and for silicate bricks). Temporary formwork is dismantled after 2 weeks.

The part of the wall that spans a window or doorway is called a lintel. Our company offers BAUT brick lintels. If the load from the floors is transferred to the wall directly above the opening, load-bearing precast concrete lintels are used. In the absence of such a load, to cover openings with a width of less than 2 m, lightweight reinforced concrete or ordinary brick lintels are used in the form of masonry on high-strength mortars with reinforcing bars to support the bricks of the lower row. Instead of ordinary ones, wedge-shaped brick lintels are sometimes made, which at the same time serve as architectural decorations for the facade.

For the same purpose, with spans up to 3.5-4 m, arched brick lintels are often erected. Arched masonry is also used for building floors in buildings, such floors are called vaulted (vaults).

Ordinary lintels are a continuation of the wall masonry. They are ordinary masonry on solutions of increased strength. The tensile forces arising in the lintel masonry are perceived by the reinforcement and laid on the formwork under the lower (first) row of lintel bricks. Window and door openings can be covered with wedge-shaped lintels. Wedge-shaped brick lintels, which are a continuation of the wall, are laid out of ordinary brick with an opening width of not more than 2 m by forming wedge-shaped seams. A variety of wedge-shaped jumpers are arched. When arranging beam lintels, just as when arranging wedge-shaped lintels, the wall must be erected to the level of the lintels.

All longitudinal and transverse seams when laying brick lintels must be completely filled. In case of insufficient filling of vertical joints from loads, individual bricks first shift, then the masonry is destroyed. Ordinary brick lintels are laid out in compliance with the horizontal rows, the rules for dressing ordinary masonry from a whole selected brick. For laying brick lintels, a mortar grade of at least 25 is used. The height of an ordinary lintel is 4-6 rows of masonry, the length is 50 cm more than the width of the opening.

BRICK LUMPERS

BRICK LUMPERS

Horizontal masonry.
The lintel consists of at least three horizontal rows of brick cladding with traditional mortar. Clamps are inserted into each vertical seam of the first row of masonry. In the horizontal seams between the first and second, second and third rows of masonry along the entire length of the lintel and beyond it on both sides, Murfor RND / Z-50 reinforcement is located.

Installation.

Consumption.

Vertical masonry in one brick and one and a half bricks.
The lintel consists of at least three rows of brick facing masonry on a traditional mortar, the first of which is laid vertically (one and a half bricks (in the case of one and a half brick masonry)), and the other two are laid horizontally. Clamps are inserted into every second vertical seam of the first row of masonry. In the horizontal seams between the first and second, second and third rows of masonry along the entire length of the lintel and beyond it, Murfor RND / Z-50 reinforcement is located on both sides.

Installation.

Laying on the edge inside.
The lintel consists of at least three rows of facing brickwork on a traditional mortar, the first of which is laid on an edge perpendicular to the bearing wall, and the other two are horizontal. Clamps are inserted into every second vertical seam of the first row of masonry. In the horizontal seams between the first and second, second and third rows of masonry along the entire length of the lintel and beyond it, Murfor RND / Z-50 reinforcement is located on both sides.

Installation.

Consumption (for each type of masonry is the same).

These methods are used to install window, door, fireplace openings up to 2.00 m. When working at high temperatures (in summer, for example), in order to achieve nominal strength, it is recommended to moisten the masonry for up to 2 weeks (relevant for masonry made of silicate bricks). The grade of the solution must be at least 100. After 2 weeks, the formwork is disassembled and a "hanging" brick remains above the opening.

VENTILATION

In the presence of an air gap between the bearing and facing wall, it is necessary to install ventilation boxes.

Advantages:

• protection of walls from rodents and other pests; V
• ventilation and drying of the inner surface of the facade, which ensures its durability;
• absence of efflorescence (salt stains), mold does not form;
• the insulation is dried (dry insulation is a guarantee of the durability of thermal insulation);
• protection from precipitation (especially with intense side rain);
• condensate outlet to the outside;
• matched to the color of the masonry, they are almost invisible, which does not spoil the impression of the facade.

Rules for placing ventilation boxes:

In vertical masonry joints with a frequency of 1 ventilation box - 3 bricks.
In buildings up to 2 floors - 2 rows of masonry with ventilation boxes (below, in the first row of facade masonry and at the top - under the roof overhang).
In multi-storey buildings - an additional 1 row every 2 floors.
Additional ventilation boxes above and below openings.
The ventilated air layer should be within 30-50 mm.
At the junction of the foundation with the walls, not only horizontal, but also vertical waterproofing to a height of at least 150 mm should be provided.

Brick lintels

Window/door openings - places that require special arrangement. Architects usually try to highlight such areas visually, not forgetting that they need to be made reliable and durable. Lintels in brickwork can take the form of:

• standard,
• vertical,
• on the rib
• one and a half bricks
• combined and other non-standard options.

To strengthen the masonry in these places, special reinforcing materials are used. The use of fasteners allows you to make jumpers for buildings with brick walls as strong as possible. They:

• gently fix corners / other uneven transitions,
• prevent the appearance of cracks in the masonry,
• will contribute to a more even distribution of the load on the bricks.
