House of foam blocks with their own hands
The house of the foam block is a great solution for every developer. Such a structure differs among buildings of other materials with a relatively low cost, minimal construction time, resistance to rotting, as well as fire. The walls of the blocks are warm and reliable. In this article we will describe how to make a house out of foam blocks with your own hands.
Foundation
The first step is to create a foundation that can withstand a foam block house:
- We make calculations of the width and depth of the formwork system. The width is equal to the cross section of the structure under construction, and the lower point depends on the climatic conditions of the area and the degree of soil freezing. The depth of the foundation must be at least 500 mm.
- Further, a trench is dug, the depth of which is about two meters.
- Coarse sand (300 mm) is laid at the bottom of the trench. Then the sand cushion is moistened with water and well compacted.
- To give exact forms to the foundation, formwork is placed, and strips of roofing material are fixed.
- Along the perimeter of the trench is installed fixing belt of reinforcement.
- Then you can pour the foundation with a special solution (5 parts of crushed stone, sand - 3, and cement - 1).
- We move the formwork, increasing the construction of the foundation. During pouring, asbestos pipes are arranged for laying sewage in the places determined by the scheme.
- Every 50 cm of concrete solution should be compacted.
- Foundation как минимум в течение месяца «созревает». Во время застывания накрываем его от ультрафиолетового излучения и периодически смачиваем водой.
- Above the concrete structure it is necessary to roll out the moisture insulating material.
- On the outside, a blind area is constructed, its width is from one to two meters, and its height is 150 mm. This is done so that natural rainfall is diverted from the first floor or basement. It should be divided into sections to prevent various deformations or ruptures.
Masonry walls
Blocks of foam concrete exceed brick in terms of heat saving and sound insulation, but at the same time, large-scale patching between foam blocks reduces these parameters to a minimum, and “thermal gaps” are formed.
During laying, it is necessary to comply with all building standards for erection, in other words, to reinforce places under door and window openings, supporting lintels, etc., using fiberglass weaves. Thus, the house of foam blocks can be insulated.
Very carefully it is necessary to lay the 1st row, checking the verticality and horizontal position of the structure with a water level. Fix the roughness is easy, as the foam blocks are well processable - cut, planing and much more.
To install the fittings, cut holes of 0.3 ± 0.3 m on the surface of the foam block using a circular saw. After which they are filled with a special adhesive solution. In the planking form on the top row of blocks is performed reinforcement screed 0.2 m.
Externally, insulation is performed with glass wool insulation or polystyrene foam 5 cm wide. This is necessary for the walls to "breathe". The first row is laid using cement mortar, the second - on a special glue. The height of the cap should be 0.4 m.
Further, outside the mineral cloths are fixed with plastic anchors. Above them should be fixed wind and hydroprotective material. The front wall is placed on the cement mortar with the principle of a spoonwork. At the same time, the tychkovy row is placed every four rows of spoons. In order to increase air circulation, it is necessary to separate the front masonry and the main wall in 5 cm intervals.
In case of brick cladding, the front masonry should be connected every 5 rows with blocks using flexible anchors and fiberglass material (cracks may be formed when using stiff materials).
For the construction of any structure, it is possible to use heat-efficient blocks that combine simultaneously three layers: claydite concrete, polystyrene foam and concrete. From the outside, dye is added, and the front side resembles the texture and color of any stone or facing material.
Overlaps
The overlap design is carried out according to the finished scheme, which gives an idea of the interaction between the beam load, the span size and the cross-section of the bars. You can use boards connected with screws. The ends are sawn off at a certain angle - 60 degrees. Then there is an antiseptic treatment and wrapping with bitumen.
Initially, the final beam beams are laid, then the rest. Beams of 200 mm and more are placed on the wall structure. The sub-basement should be insulated with a special film and insulation. Above the bars fastened metal crate. Then superimposed mesh of fiberglass and mineral insulation. On the top floor are fastened sheets of plywood and balzatovolokno. At the end we cover the floor with chipboard sheets.
The roof of the house of foam blocks
It is necessary to build a rigid structure using a bar-shaped crate and complementing it with truss trusses. Between the rafters should follow a certain distance - from 600 to 900 mm, the dimensions of the rafters range from 50 to 150 and from 100 to 150 mm. They are installed at an angle of 20 degrees.
Galvanized iron is better suited for skate, but endova from it turns out quite good. To continue the "life" slate roof, you need to paint it with a water-dispersion coating. In this case, the service life of the roofing material can be increased by 1.5 times.
Installation of slate coating
- The boards are attached at right angles to the rafter legs. Their size is 2.5 × 10 cm and an interval of 0.2 m.
- Then, angular edges are cut on slate sheets. This is done in order to prevent the layering in the places of their docking.
- Next you need to make holes at a distance of 0.1 m from the edge. Note that the diameter of the hole must be greater than the diameter of the nail.
- With the help of nails with a round cap slate is attached.
- It is necessary to begin to beat slate from the bottom row. Holes are prepared in advance.
A house made of foam blocks is warm, reliable and stable. In this structure you can live with the same comfort as in the brick. The building withstands the vagaries of the weather and is capable of comfortable living in it.
