Partitions made of concrete blocks , device and installation technology

Partition represents excellent technical design tool that allows one large room to do a lot of little, oreven just to zone the room, dividing it into certain functional parts.Depending on the placement of her different requirements:

• strength.There must be a strong and stable material for such partitions can be a gas block wall, brick, pazagrebnevye plates and expanded clay blocks.
• must have good sound insulation svoysntvami.Here, preference is given to porous materials and vozduhosoderzhaschim.

But creating a partition in an apartment or house, you should take into account the strength of the grounds on which it is located.On the wall is made from concrete towers to erect brick is not recommended, because of the rather heavy weight of its violation may occur in the integrity of the building.Not to mention the hardwood floors, where even a light and porous material, a foam block or aerated concrete is not necessary to install.Under these conditions, then it is better to use a drywall or wood.

most optimal both in value and in the created load are aerated concrete walls.The material from which they are constructed, has the following properties:

• Excellent withstand heavy loads on squeezing.In this aerated property indicates the density, which is expressed by numbers D200, D300, D400, D500, D600.She points to the hardness of the material and perhaps permissible load, which it is able to withstand.But at the same time with an increase in the density of heat-insulating properties deteriorate.Interior walls can be aerated concrete build, and even better from the D500 and the D600, because the insulation, in principle, not relevant, and the strength to be high, that would be on the wall could still attach furniture.
• good at trapping heat.This feature is provided by the content of a large number of gas balls (long).They can be formed in two cases where the present catalyst (foaming agent), and the unit thus baked in an oven.The second method - without the use of blowing agents, and the block hardens under normal conditions, but then this material, although it has a similar chemical composition, the foam has a name.But let's talk about it in the next article.Aerated concrete bulkhead can be an excellent insulator against cold room warm, making it an optimum microclimate due to porosity.

• Wall made of concrete blocks does not emit toxins, poisonous fumes and other harmful substances.Besides aerated not burn or deformed even on prolonged exposure to high temperatures.This implies another property - security.

Aerated concrete as the main construction material

Aerated concrete has long been used in the construction of various buildings of any purpose, because it is easily subjected to further processing.It is possible to tighten the screw, hammer a nail, plane and even ordinary stamestkoy hacksaw to saw wood.But for the elapsed time of manufacturing technology has undergone some changes.Blocks become perfect geometrical dimensions are identical to each other in a series of product mix manufactured with grooves and ridges to facilitate their installation and the reinforcement.If earlier installation of gas-concrete walls came down to the side planing surfaces, plastering layer to 5 cm, now a wall of aerated concrete is almost ready plaster and wallpapering after its erection.

Choice binder composition

Today there are several opinions on what the solution should be used to block installation:
Some say it is better to use the old fashioned way - mortar, it can and sobecause it is warmer than the sand and wherein the complete drying and low cement content is white in appearance.But he has a downside - it is very fragile.If you are using such a solution, the reinforcement of each layer must be performed without fail.It is better to be suitable for the construction of thick walls and partitions not.

• Special cement-sand glue.It contains a plasticizer and a hardener, which allows it to smear a thin layer, providing virtually seamless connection blocks.That is why we consider how to put on the glue aerocrete.But first it is necessary to buy.It is sold in paper bags on which is written "for gazoblokov Clay."It is also possible to apply the tile adhesive, it has the same properties.

How thick should build walls?

partition of concrete blocks can have very different thicknesses, depending on the expected properties of it.If it should become part of the supporting structure, it is necessary to use a block of at least 200 mm in thickness and density of the D400.For easy distinction enough space and 100 mm.In general, commercially available all possible sizes, which can come in handy in the construction, with the help of foam blocks is possible to build and beat various designs.

partitioning technology of constructing concrete blocks

Any work must be carried out efficiently, so we offer you these instructions on how to put gazoblkoi whose photo in front of the eyes of the process.

Substrate Preparation

Before considering the technology, how to put aerocrete, should prepare the ground.It should be cleaned from dust and protruding elements of the old solution, primed, pre-made tie, if necessary.Deviations from the level of more than 3 mm may lead to inconveniences for further work.

Though blocks and produced by machine in the automatic line, but they will have a deviation from the geometry.So be sure to get a special grater for aerated concrete.With its help, you can easily get rid of the sagging, sticking block elements and protruding corners.

After cleaning the base, can begin installation of gas concrete walls, but before it is necessary to put the control layout, which will be carried out by stacking each of the rows.You can use the building trace cable, laser level or attach the guide bars to the walls and floor.Due to their ideal geometry will be maintained at the edges of walls, and by means of the lace and the middle.

When laying the first and subsequent series cast throw slit septum and the main wall connections are not recommended, in order to improve the sound insulation properties.It is better to patch up later with foam.

Mounting blocks on

solution now talk a little bit about how to put the blocks on the solution.In this method, there are advantages.Due to the thick first layer can be aligned not entirely flat surface already with blocks.But subsequently the mixture spread on all the contacting surfaces with a thin, no more than 2 cm, bed periodically obscuring the seams on both sides.

Apply glue

Now consider in more detail how to put on the glue aerocrete.It is the same mixture of sand and cement, but contains a specific plasticizer and a sticking agent, which allows the next day put considerable load on the wall.To work with glue need a special trowel with teeth and the size of a block itself.This will not only faster and better perform namazochnye work, but it will help save the glue on the losses.

All armed with a trowel, putty knife, trowel and level you can get to work.Stack the blocks starting from the wall or from the angle of the turn-up partition.If the surface is smooth, then apply a thin layer of glue is enough.Laying gazoblokov should be carried out smoothly and efficiently, so after the installation of each of them should be carefully obmeryat from all sides and to monitor the convergence of the indicative lace.

Why is it better to use glue?

Laying concrete blocks on the adhesive provides greater strength and stability of the wall, due to the deep penetration of the adhesive to seven, thereby forming a solid seam.A thin, almost missing the seam solves this problem, as the cold island, making the wall more warm.

process of laying

blocks Installation walls of concrete blocks is as follows:

step back a little from the wall (literally 5 mm), installed the first block, carefully equating it to the fixed bars and trace the lace on the pre-plastered uniformly thin layer of adhesivecomposition.Masonry walls of concrete blocks should be done qualitatively, this applies casing unit in place.This operation can be performed using a rubber mallet or lining it.Instrument on all sides, and cased the block level is controlled by its place of purchase.

also possible to mount partitions of aerated concrete slabs with grooves and ridges.They produced the same sizes as gypsum board, but have slightly different properties from them.

Laying concrete blocks further repeated until the opening at or before the wall with a space from it in 5 mm in order to improve the sound insulation properties.Each row of baffles 100 mm thick should be reinforced and linked to the load-bearing walls or other barriers.This can be accomplished by using reinforcement pieces with a diameter of 6 mm or more.For this purpose in the wall at the level before mounting it on the seat unit angle drilled hole length 1/2 valve.She herself may be 15 - 20 cm. The aerated concrete block for partition using manual or stomestki wall chaser selected the appropriate slot for the free penetration of reinforcement.

When mounted in a hole in the wall and the groove is applied the same solution for masonry gazoblokov and bricked it a bunch.This reinforced septum compound will provide the necessary strength, regardless of its thickness.When using the blocks 150 - 200 mm stapling to the walls can be done through a series.You also need to consider dressing themselves between the blocks, shifting subsequent glad 1/2 block thickness.

also as a binder, you can use perforated angle, bus, and self-tapping screws or nails to fix it to both surfaces.But this method is less strong compared with the first.

Making door or window opening

partition of concrete blocks have low weight (1 monolithic block sizes 600h300h100 mm and weighing 10.5 kg replaces eight bricks weighing 24 kg) due to the porosity of the material used masonry, so doorways andarch width up to 80 cm can be carried out without jumpers.It's enough to put the blocks overlap on the wall 20 cm, densely stykuya them together in the middle of the opening.For their temporary support, you can use a framework of wooden beams, self-tapping screws screwed to the blocks on the level of their placement.

device gazoblochnyh walls with openings wider than 80 cm require mandatory use of jumpers.As they can be monolithic reinforced concrete, the two corner edges and even wooden beam pretreated antiseptic composition.

installing aerated concrete walls, the installation should be made not to the ceiling.It is recommended to leave a space in the 1-1.5 cm. It is better to fill with foam.This is done in order to avoid cracking of the walls at the edges of the ceiling vibration and provide better sound insulation properties.

mounting End

should carefully check for the presence of gaps After the erection of walls of concrete blocks in the joints and using the same glue them repaired with a spatula.After full hardening of adhesive (not less than one day) and before further processing aerocrete block walls must be treated with antiseptic hindering development in these fungi and other pests.Wall and perhaps build out gipsoblokov, more detailed information can be found on the website in the section of the wall.
