Mauerlat: Sizes and calculation of materials

The Mauerlat and the rafter system make up the two primary parts of the house’s roof. A solid foundation that functions as a mount for rafter bars is mauerlat. For a precise and trustworthy design, it is crucial to precisely calculate the size of the building materials when constructing the roof. Examine the fundamental guidelines and recommendations for measuring the Mauerlat in order to procure the required material size.

Calculation of the size of the Mauerlat

The Mauerlat is the exact first component of the roof structure to be built; it provides stability, support, and an even distribution of the structure’s weight along the house’s walls. For this reason, determining the Mauerlat’s exact size is crucial.

The following variables affect the size of the Mauerlat:

The parameters of the area of the house – its perimeter and area.
Type of roof structure.
Material used in the rafter system and to cover the roof.
Climatic conditions.
Is an attic area or not.

The view of the roof serves as the primary indicator for determining the Mauerlat. There are several types of roof structures. The following are the most common ones:

Classic – single -sloping, gable, tricketeral or four -skeet roof.
Cross -shaped.
Folded.
Flat.
Spherical.
Sertic, semi -oval and holm.
Spire -shaped.

Therefore, the type of roof for which the Mauerlat is intended must be known in order to calculate it. We’ll talk about how to figure out the Mauerlat sizes for the traditional gable roof. However, you should ascertain the computed parameters shared by all types of roofs before proceeding with the consideration of the Mauerlat for a particular type of roof.

Additionally, this article describes the Mauerlat’s insulation, waterproofing, and device.

Formula for calculation

Measure the length and perimeter of Mauerlat before proceeding with the measurement. Measure the beam’s upper portion. The Mauerlat’s smallest section measures 100 by 100 mm.

Then came Determine the volume and weight of a wooden beam. This formula can be used to determine these indicators:

M = RV

R is the density of the tree,
V – Mauerlat volume,
m – how could you guess a lot of wooden timber.

The following formula is used to determine Mauerlat’s volume:

V is equal to SL.

S is the cross -section of the wooden beam,
L – its length or perimeter.

What size would not be Mauerlat, the main thing is to place it at least 5 cm. from the outer edge of the wall.
For most cases, an antiseptic wooden beam made of deciduous wood with a cross section of 100 × 150 mm is suitable.
Wooden beams should be laid out along the entire length of the walls, from one end of the house to the other.
Next, you should take the necessary measurements, making sure that the distance between the bars is uniform along the entire laying length.

Settlements for a gable roof

The most common and straightforward kind of roof is the gable roof. Because of the roof’s slanted design, rainwater or talus snow falls naturally from the surface of the roof. Although installing a Mauerlat for a gable roof is expensive and time-consuming, it guarantees the resilience and longevity of the roof structure.

Wooden bars with a cross section of 10 x 10 or 15 x 15 cm work well for gable roofs. The indentation from the outer edge of the wall should be at least 6 cm, and the thickness of the Mauerlat should not be less than 10 cm. There should be at least 40 cm between layers when using waterproofing material. Installing the racks mentioned in the lying is also advised. They ought to be separated by three to five meters.

In summary, a variety of factors that dictate the proper parameters of the material for fastening should be considered when calculating the Mauerlat. Finally, we provide the primary Mauerlat parameters that are appropriate in the majority of situations:

Mauerlat width should not be less than 10 cm.
The optimal cross section of wooden beams is 10 × 15 cm.
Suitable material for Mauerlat – antiseptic bars made of deciduous wood.
When calculating the mass and volume of Mauerlat, be guided by the formula of the above.
The indentation of the timber from the edge of the wall should be at least 5 cm.
The distance between the Mauerlat bars should be uniform on all segments of the structure.

Mauerlat: Dimensions and material calculations The roof structure is based on the Mauerlat. Mauerlat installation is always labor-intensive, but selecting the appropriate material parameters is the first step in the process.

"Anyone working on roofing or building a house needs to know how the Mauerlat works in a gable roof. In order to provide stability and evenly distribute the weight of the roof, the Mauerlat plays a critical structural role by anchoring the roof to the building’s walls. This article examines the role of the Mauerlat, including its location, composition, and importance in guaranteeing the longevity and security of gable roofs. Understanding its purpose and using the right installation methods will help both builders and homeowners improve the roofs’ longevity and structural integrity."

Installation of rafters on a double -sloping roof Mauerlat

The foundation to which rafters are fastened is the mauerlat belt. Attempt to secure them as tightly as you can. This determines how long the roof will last. Murlat is another name for mowerlat foreheads. You will grasp our conversation after just one listen.

About Mauerlat

Mauerlat moved around the outside of the walls. It’s going to be up on its rafters. Its job is to securely fasten the roof to the building. so that a hurricane’s wind doesn’t disturb it. The load is distributed evenly to the house’s walls because of Mauerlat.

Make an effort to handle the installation sensibly. What is happening when the house is constructed without the use of Mauerlat? Naturally, if the ceiling beams are sturdy, the rafters are fixed to them. As it happens, the weight of the roof presses against the areas where rafters are supported. In contrast, Mauerlat distributes the load evenly across the walls.

Peculiarities

Under the Mauerlat for gable roofs, a beam will typically be seized rather than entire logs. It’s easier to work with and more convenient. The beam is stable and has ribs. It won’t fall if you place it against the walls. When building a roof, mauerlat is crucial, so follow the instructions and choose a beam with the appropriate diameter. And what particular requirement exists? It is dependent upon various factors:

The total area of the house and how much the perimeter of the walls occupies?
Type of roof,
The material that the roof is covered,
The material from which the supporting structures are made,
Climate in this area,
Is there an attic, several or other extensions?

Which material can be chosen under the Mauerlat?

Wood, and specifically – beam,
Metal,
The beam is double -barrel,
Channel.

Think about various options.

A beam is a suitable material to use when building a gable roof. You must have material with one of these sections (in centimeters):

The material walked along all walls, placing the rafters beneath the feet. This will ensure a uniform load on your new home.

Whenever you decide on wood. Take note of any knots that may be present along the beam. They must not exceed two thirds of its thickness. Why? Since the knots prevent the material under load from stretching as it should.

In the unlikely event that you encountered knotted wood and were unaware that such bars could not be installed, cracks or multiple cracks could quickly appear on a wall or multiple walls. This indicates that the material was unable to support the weight of the roof as a shock absorber.

Boards secured

For instance, if you are building a country house without a heavy roof, you can save some money by using a little heavier wood instead of lighter material. Planks attached to one another. It is going to be a nice Mauerlat.

It occurs that the structure is combined, using steel pipes and a maowerlat made of wood at the same time. Wooden beams are used to attach pipes to the house, but they do not extend behind the structure. When the gable slope is at the roof, they bear the majority of the weight.

Beams are frequently utilized in addition to the installation of Mauerlat. The pipes are required to meet the following criteria:

They should be small in section. Holes are made in the rafters and pipes are extended through them,
Choose steel pipes. After all, they will hold the entire roof on themselves.
Steel should be of high quality. It is unacceptable for the material to undergo deformation over time.
In the rafters, holes are made along the axis. Their diameter should be smaller than 10 cm, the height of the label. It doesn"t work like that? So, additional steel mounts are needed.

The fact that steel pipes can bend so well and are strong enough to support the entire roof despite their small diameter is fantastic. Furthermore, they won’t be harmed in any manner by the rafters’ tiny holes. They can sustain the required loads because of their strength.

The fact that Mauerlat is covered in this design is excellent. As a result, he won’t be exposed to the rain or snow and won’t start to rot.

Mounting Mauerlat

There are various methods for attaching this material to the walls. Think about the available fixing options:

Brickwork. It is required to fix the structure to wood bars, which are smiled into the wall from the upper end below by 2 or 3 rows. Fasten it with brackets.
Blocks with cells. For such fastening, a reinforced concrete is poured at the roof. In the fill, you need to leave threaded studs Ø from 1.2 and up to 4 cm. They are installed from each other after 150 and up to 200 cm. In the workpieces for studs, you need to drill holes. Mauerlat bars are attracted to the wall. It will take nuts with washers.
If you are still building brick walls. Then the hairpins can be gripped directly into the masonry. 3 rows – this is a sufficient depth. So that they are well fixed. Ordinary fittings will cost cheaper. Nuts are welded to it.
In brickwork, retreating from the upper end of the wall of the 3rd row, you can invest 3 or 4 mm of steel wire. The ends need to be brought out on both sides: outward and inside. Such a length is required, which is enough to tie the Mauerlat bars.

Masters claim that they can mount Mauerlat in any manner upon request from the client, but if you choose to do it yourself, you can benefit from the knowledge of experts.

Another way of laying

People take the 50×150 mm cut boards under the Mauerlat. These boards must be inserted into the walls in a single row. Anchor screws hold them in place; a screwdriver makes it easy to tighten them. Bolts are useless because their heads get in the way. The minimum required anchor length is 20 cm.

Allow the joints at the boards to protrude; you will receive a dressing. Lay with dressing in a similar manner in the board’s corners. Mauerlat will protrude by 10 cm.

This approach is beneficial because

The boards are easier than Brusiev and it is easier to lift them to the house under construction.
For boards you do not need a time -consuming cut in half a derer.
It is easier to carry out work. When the brigade erected the walls, and the owner decided to put the roof on his own. After all, mason is unlikely to occur. That on the walls you need to lay studs or wire, bars.

The hired workers who carry on with their construction must contend with the fact that their predecessors built the brigades; however, if you install a gable roof on your own, take care to secure it to Mauerlat. A strong meter will then prevent it from breaking and from even moving to the side, which may cause a crack in the wall to appear.

What size should be Mauerlat?

Not every word used in the professional jargon of builders is clear to the average person. Professionals frequently bring up Mauerlat in conversation. Not everyone, though, is aware of what it is. In common parlance, a mauerlat is a building’s roof support structure that consists of a roof and a rafter system. It serves as the roof’s base and foundation, uniting every component of its construction into a single frame.

Mauerlat compensates for variations in the roof’s design position and forbids even a slight incline in any direction. After all, it is difficult to construct the walls precisely and to maintain a uniform height around the building’s perimeter.

The rafter elements should be firmly fixed to the roof’s base. As a result, to guarantee a sturdy attachment of the rafters, it is crucial to precisely determine the size of the Mauerlat when arranging a roof.

As a connecting element between the building’s walls and roof, it evenly allocates efforts to the base’s shape. The mass of the roof and the characteristics of the rafter structure are taken into consideration when determining the dimensions of any Mauerlat. Think about this matter in greater detail.

The traditional version of Mauerlat (see photo below) consists of a dried log or timber that is affixed to the exterior walls or armopod around the house’s perimeter.

Features and purpose

In the traditional execution, the external walls of the building are surrounded by a circuit of dry beams or log blankets that serve as the supporting structure. Mauerlat carries out the subsequent duties:

evenly distributes the efforts transmitted by the rafter elements to the roof base area, compensates for local point efforts in the places of support for the rafters,
Carries out the roof to the supporting walls, being between them a reliable mediator, which is especially relevant for areas with significant wind loads.

The expediency of the structure

The Mauerlat device is required to offset the following kinds of loads on the building’s roof:

Vertically acting efforts transmitted by the mass of the roof, as well as wind and snow loads.
Horizontal components from spacer loads transmitted from the rafters located at an angle, trying to push the construction contour.

Since working with the Mauerlat is much easier, it is typically installed from the beam rather than the log.

Which affects geometric parameters?

Generally, a wooden beam is a better option for manufacturing than logs because it is easier to work with. Because of the cross section’s rectangular shape, installation is made easier and more stable.

The following factors are taken into consideration when determining the Mauerlat section, which is determined with extra care due to the unique function assigned to Mauerlat:

geometric sizes of the built building,
roof structures, including the material used to cover and manufacture the rafters,
features of the climatic zone where construction is carried out,
the presence of attic building, increasing the load on the outline.

The primary factor influencing the support frame’s size is the roof’s actual design:

Classic form with one to four slopes.
Pyramidal outline with spire -shaped elevation.
Folded type.
Flat species.
Spherical or tent form.
Cross -shaped, broken configuration.

Mauerlat’s roof structure plays a crucial role, so choosing the beam’s size (section, thickness) should be done carefully.

The configuration, the roof’s features, and its mass are all taken into consideration when choosing the Mauerlat section. The most widely used traditional measurements, in millimeters, intended for the following kinds of structures:

small architectural forms – 100 x 100,
gable roofs – 100 x 150,
reinforced structures – 150 x 150,
complex attic buildings of residential buildings – 250 x 250.

General recommendations

Observe the following guidelines for the support frame’s geometric sizes, regardless of the parameters:

Install an Mauerlat with an indentation of 5 cm from the outer circuit of the walls.
Pre -priority impregnation with an antiseptic.
Put the bars around the entire perimeter without gaps.
Use woodwood wood.
Control the distance between the bars using an accurate measurement tool.
Fix the supports to the walls, using threaded studs installed with an interval of 1.5-2 meters.

How to calculate?

Multiply the wood density by the Mauerlat’s volume to find the mass of the supporting beam. The method of calculation is very straightforward. The cross-sectional area of the Mauerlat is its thickness divided by its width. We obtain the volume by multiplying it by the support element’s length.

We’ll talk about geometric size recommendations using the example of a typical roof with two slopes.

The triangle section’s roof is incredibly sturdy and stable. Because of the inclination, sediment is able to naturally exit the surface. It takes a lot of work and effort to install the supporting structure for a roof of this kind. Long service life as a result justifies the financial and time investment.

The minimum width of a mauerlat should be 10 to 15 centimeters. Installing waterproofing material is essential for the structure’s dependable operation. The distance between support racks should be between three and five meters.

The roof’s design and the characteristics of how its components are attached serve as the foundation for calculating the Mauerlat parameters. Precise measurements taken throughout the building process are an assurance of the design’s dependability and long-term application.
