The one who was interested in the construction of a private house or even more so he had built such buildings, knows what Mauerlat is and how important its proper fastening for the entire design as a whole. For those who are not familiar with the construction case, we will explain that Mauerlat is a special wooden design, the purpose of which is the adoption of the main load from the roof and its uniform distribution on the walls of the house. It is that the legs of the rafters are attached to him, and they ensure the structural stability of the whole roof.
Mounting scheme Mauerlat to aerated concrete.
The reliable and competent mount of Mauerlat to the walls is a responsible operation, since not only the strength of the whole roof depends on its accuracy, but also its durability. In fact, Maurylalat can even be in the form of a 2-way steel beam or channel, if the roof rafters also represent a metal system, but such cases, especially in private construction, is extremely rare.
The reliability of the fastening to the aerated concrete directly depends on the accuracy of all preliminary calculations and installation techniques. The minimum cross section of a wooden bar or a log is 10x10 cm, but better. If it is planned to use a log as Mauerlalate, it must be placed on the one hand so accurate so that it fits tightly to the top edge of the wall of aerated concrete.
Selection of material and calculation of parameters
Installing Mauerlat carries two main functions:
- Uniform load distribution from the roof on all bearing walls of the house.
- Fastening the roof design to the construction box.
As the basis, a wooden beam is used in size from 10x10 to 15x15 cm.
A wooden beam is taken as the basis of the size, as mentioned above, from 10x10 to 15x15 cm. It is best to take a ram from hardwood wood, which must first take antiseptic processing. All bars should evenly cover the entire top of the walls, and a straight lock is used to reliably bonded them. At the same time, the lock is better to further strengthen, driven to the bonding of nails.

As a result, you will have a single rigid system when the bars are securely fasten with two adjacent and form a reliable support for future rafters. Brussia is always a little more than masonry from gas blocks, so they need to be shifted to the inner edge, so that the free space remains between the bar and the outer edge of the wall at least 5 cm wide. In some cases, a number of bricks are placed in the outer edge, in which the sidewalls of Maurolat will be dripped.
Remember that, before moving to the mounting of Maurolat to aerated concrete, it will be necessary to pave between a tree and a wall quality waterproofing.
Mounting Muerolat Mounts
There are several ways to fix Mauerlat to aerated concrete. Due to the fact that this fastener should be as strong as possible and not allowed even the slightest design shifts, in modern construction technology, several highly reliable types of fixation of these elements are used. This is a fastening with:- reliable steel wire;
- confused in the reinforced belt anchors;
- Metal studs sticking out of reinforced concrete belt.
Consider these types of fastening to aerated concrete.
Fastening steel wire
Mounting Maurolalat Wired: 1 - screed, 2 - Mauerlat, 3 - waterproofer, 4 - rafylo, 5 - wire, 6 - fasteners.
While laying the walls, for two or three rows before its top, there is a steel wire between the bricks in such a way that it is fixed by her middle.
Both ends should be such a length so that they are enough to reliably fix the bar to the wall. For this, the wire must pass through the hole in Mauerlat and reliably clutched.
The number of such bundles is not regulated, but their quantity is better equal to the number of legs.
Attaching anchor bolts
For better attachment, Maurolalat experienced builders advise the reinforced belt. In addition to the fact that with such a concrete belt, the mount to the bruis will be convenient and reliable, Aropoyas also increases the strength of the entire box as a whole, makes it more rigid. In addition, the reinforced belt allows you to perfectly align the horizontal the upper boundary of the walls, which is extremely important for ensuring and strength and reliability.

Mounting Mauerlala with anchor bolts.
If the walls of the house are built of aerated concrete, then the Maurelast mount is impossible without armopoya, as the aerated concrete is too soft to ensure the reliability of fixing the anchor bolts, studs or other fasteners.
The reinforced belt to build is best with the help of special U-shaped blocks that are laying out along the upper facet of the walls in such a way that a single and continuous chute line formed. At the corners, blocks are used with a spinal sideline so that the gutter line is not interrupted. It is in this chute that the reinforcement of 12 and 6 mm (transverse) rods are installed. After the installation of the reinforcement frame of the groove is poured with a concrete mixture, while they do it continuously and in one occasion.
But even before the fill with concrete in the chute reinforced belt, the anchors with carvings are installed. They are attached with a knitting wire. Their attachments should be as smooth as possible, for this it is used treaded cord or fishing line. Anchors should be as close as possible to the upper surface of the concrete and to the bruse, respectively, while standing as perpendicular to the Mauerlat line.
The number of fixtures is not regulated, but their number should be no less than the number of rafters, while you need to place them so that they do not turn out to be covered, so try to place the attachment points as accurate as possible.

After soaring the concrete solution, the anchors turn out to be reliably fixed in its thicker. This mount is the most reliable of all imaginable options.
After finalizing the concrete belt and the anchors are stacked in such a way that the anchors penetrate in advance drilled in the tree of the hole. After that, the mount occurs by twisting the nuts with the washers.
To accurately calculate the places for the future hole for the anchor bolts, you need to put the beam over the bolts, and then hit several times with a pyanka or its analogue from above. In the wood will be dents from contact with bolts, here at this place and you need to drill holes.

Sometimes it is not a solid concrete belt for savings along the entire length of the wall, but separate concrete pillows. That is, they make an analogue of the pit in the brickwork, which fit the reinforcement and poured concrete on the same technology as the belt. There is also necessary to attach anchor nests to reinforcement rods.
Fastening with metal studs
Mounting Mauerlat with metal studs.
If you have a small house and the pressure on it from the roof side is not supposed to be too large, then for the fastening of walls with the Mauerlalate broom, you can use a lighter mounting option - stiletto walls. These studs are steel attachments in the form of bolts with a cross-branch or base in the form of a square with the sides of 5 cm.
Even at the stage of the construction of a brick masonry in the wall, the studs of the studs are configured, they are installed in one or two rows until the end of construction. The free length of the spills should be sufficient to go through the bar or lock the lock nuts.
Further technology resembles fixation using anchor bolts. There are also places for drilling holes, bars are installed and the nuts are tightened.
The importance of waterproofing during installation
By choosing one of the proposed mounting options, perform an accurate calculation of the required fasteners and their future location. In addition, it is necessary to carry out one important event.
This is the provision of good waterproofing.
Several layers of suitable waterproofing should be labeled between the wall and the timber of the bar.
It can be both simple rubberoid or polyethylene and expensive modern materials. The need for such isolation is extremely important, since without it, moisture will accumulate at the point of contact, which is capable of destroying the entire structure of wood as soon as possible. Only after laying the selected isolation can continue the installation of Mauerlat.
