How to construct an inexpensive sauna with a trim from a beam
It is believed that the real bathhouse should be constructed of wood. However, a real log deck and expensive and it is difficult to protoplit, therefore, we have to look for some alternative. The national encyclopedia of construction of ProfiDom.com.ua, tells how to build a bath, using modern materials and, at the same time, provide an authentic appearance of finishing.
The general concept
One of the common building materials today is aerated concrete. It has good heat-saving properties and a fairly high compressive strength, which makes it possible to lean on such walls, even monolithic floorings. However, gas-silicate blocks have a very specific masonry technology – it is difficult to carry out reliable mounting, and the enclosing structures must be carefully designed, both according to the existing loads, and according to the climatic conditions of operation.
In addition, the aerated concrete does not have the ability to elastic deformation, which, with a minimum thickness of adhesive seams, makes the walls extremely vulnerable to oscillations of the base. If the foundation is not sufficiently reliable, the walls will crack, which will lead to loss of bearing properties and thermal insulation qualities.
These disadvantages should not confuse a private builder. In this material, ProfiDom.com.ua tells about how to build an inexpensive sauna with timber trim
The size of a building for a bathhouse needs to be determined based on the maximum number of people who will use it. For example, if there are four at the same time in the steam room, two beds with 2×0.5 m dimensions will be required, and benches and a stove will have to be placed on the lower tier. Given that from a stones to human bodies must be observed a distance of not less than 1.5 m, we get the dimensions of the steam room about 2х3.5 m.
Also, it is necessary to have a fireplace where a small sofa and a table for beverages will be put up, the minimum dimensions of this room are 2.2 x2 m. If the front panel is joined by a short edge to the steam room and insert them in a rectangle of 3.5×4 m in size, there will be a place for the vestibule and a small shower , located next to the steam room.
Adding the thickness of the walls about 40 cm on each side, we will get the dimensions of the foundation of 4.3×4.8 m. The best variant of the foundation for the construction of this type – a monolithic plate on a warmed substrate. So in the bath there will be more heat, besides, it will be convenient to expand communication and mount plums in the floor.
With a thickness of 28 cm, the foundation will be less than 6 m3 of B20 grade concrete. The reinforcement consists of two meshes: with a 180 mm step of 12 mm of rods in the upper zone and a 240 mm step of the 14 valves in the lower zone. In total, it will take 230 m reinforcement 12 mm and 185 m reinforcement 14 mm. Taking into account the stock for cutting at 5%, the total weight will be about 450 kg.
The considered configuration of the foundation is optimal for subsidence soils with pronounced uneven permeability. The foundation creates a load on the soil of about 65 g / cm2, the load from the full building is twice as large. If there is complete confidence that the soil will hold such a mass, it is possible to reduce the thickness of the plate to 22 cm and the step of the upper and lower mesh to increase to 210 and 280 mm respectively, which will allow about a quarter lower costs for the foundation.
The technique of the plate is simple: the top layer of the soil is removed, usually to a depth of 40-45 cm to the loam. After this, a gravel filling is carried out, which is stacked layer-by-step with a deck weighing 20 kg. The height of the fodder is not less than 10 cm, top it is sprinkled with dry sand and carefully shed with water. It takes about 2-3 days for drying, then the pits are filled with expanded clay to a level that makes the finished slab stand above the ground at least 120 mm. In total about 2 m3 of gravel with sand and 4 m3 of expanded clay of a large fraction leaves on the bulk.
Under the pit outline, it is necessary to erect a shield formwork and loosen it on the adjacent ground every 50 cm. The upper side is exhibited on a hydrostatic level in a single horizontal plane. After this, the bottom of the mold is covered with a film, which prevents the cement milk from slipping into the substrate. On the remote cork, you need to tie the bottom mesh, then bend the clips of the vertical bands from the trunks of the fittings and collect the upper mesh on them.
After pouring concrete, be sure to spend shrinkage with a vibrator, or at least carefully snap the mixture and knit the sides of Kiev. Within a week after filling, you should keep the plate covered with a film and constantly pour water. The construction of the box can be started 10 days after the foundation of the foundation.
Bath walls have a thickness of 250 mm and a height of 2.5 meters. About 12 m3 of aerated concrete blocks D500 and 1,7 m3 of blocks for partitions with a thickness of 100 mm will be used to erect a bath box. The amount of material is indicated without y…
