Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video Gabled roofs, most often chosen in the design of houses, withstand the tests of rain and snow well. However, so that high loads do not adversely affect walls and beams, and do not cause their deformation and destruction, Mauerlat is used for the roof. What is this device, why is it needed, how is it mounted and secured? Such questions can be asked by a person who is little knowledgeable in construction, not at all familiar with the structure of the roof. The information in this article will help you find the answers. [contents]

Correct Mauerlat: assignment

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video This the structure is a kind of foundation, like the base of the roof itself, which rests on the walls.

It consists of beams or beams that are located along the perimeter of all four walls. With their help, the walls and rafters form a stable and reliable structure. What are the main functions assigned to the Mauerlat node?

  • Creation of a general structure from the walls of the house and roof structures.
  • Even distribution of the load, from individual points to all walls.

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video We have rather harsh climatic conditions, heavy snowfalls are frequent: can happen, that the accumulation of a large amount of rainfall on the roof will cause significant damage to the entire structure.

Redistribution of the increased load allows the construction of four- or gable roofs. How can they help?

The angle at which the roof is tilted reduces the pressure of the accumulated snow on the structure, and redirects it from the vertical to the horizontal plane. It becomes, as it were, bursting, because of which it acquires the ability to influence the walls in the place where the rafters are attached to them, pointwise. Over time, this negative impact can not only deform the wall, but also violate its integrity.

When is it necessary to overlap the Mauerlat?

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video If the structure is built of wood, or built according to the frame type, it makes no sense to mount the Mauerlat as a separate structure.

The wall, more precisely, its upper part, will quite cope with its functions.

If the building is made of bricks, foam blocks, aerated concrete and other similar materials, then its walls must be reinforced with Mauerlat. The same material is used for its construction as for the roofing.

Usually, wood is used in this capacity, which is a relatively cheap material, quite affordable, environmentally friendly and quite convenient to work with.

This device can be made of metal, but this material is more suitable for large industrial buildings, in which the load on the roofing system significantly exceeds that in residential buildings.

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video To ensure the strength and reliability of the structure of the wooden Mauerlat, it is preferable to use solid beams for it made from an array.

In the event that the wall is too large, and it is not possible to select the material of the required length, then the individual beams must be connected as securely as possible.

It is necessary that the place of their connection is exactly in the middle of the wall, so that each of the parts of this beam is as long as possible.

Let's say this: if there is a six-meter long timber and a four-meter wall length, then you will need two equal pieces of four meters, not two and six.

Installing the Mauerlat

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video There are certain rules for the design of this system.

The width of the timber should be approximately one third of the thickness of the bearing wall, this value is usually about twenty centimeters.

Do not try to make the cross section of the maeurlat wider in the hope of obtaining a more reliable device, this can only complicate the situation.

A thick beam will also have a significantly increased weight. Not only will it make a much greater load on the walls of the building, its mass will also complicate the installation of this structure.

To prevent damage to wood, a layer of waterproofing material must be placed between the wall and the Mauerlat.

You can use the simplest roofing material.

So that the wood is not damaged by microorganisms, it must be carefully treated with an antiseptic composition. The beams are placed closer to the middle of the wall, or closer to its inner part, so that at least five centimeters remain to its outer edge.

Mauerlat fastening with wire

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video This method is one of the simplest in the device.

A metal wire with a diameter of five millimeters or more is required, which is placed about six rows deep into the brickwork.

It must be of such a length that it is enough not only for the entire volume of the Mauerlat, but also the remaining ends are sufficient for twisting with each other.

Through the entire thickness of the bar, paired holes are drilled for the wire, at a distance of about thirty centimeters, the ends threaded through them are twisted tightly. The number of necessary twists is determined in the process, but definitely their number should not be less than the number of rafters.

Stud Attachment

This attachment looks like a metal pin, resembling the letter L, as it is bent at 90 degrees with different side lengths. A square metal plate with a side of five centimeters can also be welded to the stud.

Marlat and stud fastening

These metal products are placed in the depth of the masonry at a distance of approximately 45 centimeters .

In this case, the metal square of the hairpin, or the short crossbar of the letter "G", should be located below.

The length of this mount should be sufficient for the entire width of the Mauerlat, and at least three centimeters should stick out. Washers, securely pressing the device to the wall, are wound from above.

Mauerlat: fastening to the wall with bolts

Anchor bolts can be installed directly into the reinforced belt itself, filled with concrete mortar.

When dry, the construction provides a secure hold of the Mauerlat.

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video According to the number of such pins, there must be no less than the number of rafters available. Their placement must not be the same.

Bolts should be as vertical as possible, and as aligned as possible.

After the pins are in place, a Mauerlat is placed on them, then they are hit hard with a special hammer.

From the impact, marks are imprinted on the surface of the timber, along which holes for anchors will then be made. The bolts ensure the strength and reliability of this device.

Armopoyas: Mauerlat fastening

Do we fix the roof Mauerlat on the walls with our own hands? Installation types- Overview + Video Sometimes the use of a reinforced belt it is simply recommended, and in some cases it is strictly required. What does it depend on? When a dwelling is built from materials such as expanded clay concrete or aerated concrete, any attempt to drive any fastening into the walls of the building can be fatal. Due to its relative softness, the material can begin to degrade.

To prevent this from happening, an armored belt is used, which helps to install the Mauerlat without damaging the integrity of the structural elements.

However, professional builders advise using a reinforced belt for structures made of sufficiently hard materials, such as, for example, brick, because this structure has many useful qualities:

  • Corrects not too even masonry of the walls in the horizontal direction;
  • Helps to maintain the wall structure during ground movements and earthquakes;
  • Distributes more evenly all the existing load;
  • Gives construction of special rigidity and additional strength;
  • Very reliably and firmly holds the Mauerlat.

Armopoyas: device

First of all, a formwork is made, into which a concrete mixture is later poured. The width of this formwork should be equal to that of the main wall, the dimensions of the entire structure should be at least 25 by 25 centimeters.

..

With their surface they form a single groove, convenient for pouring. To form a single internal capacity of the trough, all excess transverse walls must be sawn through.

Reinforcement cage is placed in the resulting gutter or in the formwork.

It is made of four thick (from 12 mm) longitudinal pins, on which, at least every 25 centimeters, they arrange a transverse jumper made of eight-millimeter wire. Threaded anchors are wire-attached directly to the reinforcement cage itself.

The belt should be poured with concrete mix without interruptions to ensure that the resulting structure dries simultaneously, without the formation of joints and seams. To prevent the formation of cavities and air cavities in concrete, it is pierced with a metal pin while it is in a liquid state. Do we fix the roof Mauerlat on the walls with our own hands?

It is advisable to install the Mauerlat, since its use will ensure the construction of a really reliable and solid dwelling that is not afraid no serious cataclysms, whether it be snowfall or stormy wind.

If the Mauerlat is made according to all the rules, in addition, a reinforcing armored belt is used, you will be satisfied with the reliability and strength of your home. It will become a real fortress for you!
