Tip 1: How to build a house out formwork

unlikely that we can confidently say that the monolithic house is more economical than built of blocks of the same material - it depends on many circumstances.However, in some respects it has certain advantages.For example, for thermal protection, under the same wall thickness and the same materials - due to lack of thermal bridges formed by seams of sand and cement mortar in the masonry walls of the blocks.
you need
  • - a type of cellular concrete;
  • - cement;
  • - sand;
  • - material for formwork (Edged board, hardboard plates, beams, etc. .;
  • - fittings;
  • - roofing;
  • - bitumen mastic;
  • - building tool.
Select the material for the walls and house and formwork . Best of all as a material for the walls of a monolithic house a suitable cellular concrete: slag, expanded clay, foam. They have a low thermal conductivity, a sufficient strength (with the rightchoosing a brand of concrete), and relative cheapness. Especially good qualities for monolithic pouring foam has - due to it
s concerns plastichnosti.Chto formwork , the market offers ready-made formwork from a variety of materials, including non-removable made of polystyrene foam, which, after pouring the solution remains in thethe wall and acts as insulation.However, the cheapest is, nevertheless, a wooden formwork in the form of shields, transposed from place to place during pouring.
Pour the foundation under the house .Lay it on top of the waterproofing mastic asphalt and the two layers of fluff from all sides roofing mastic.
Fabricate formwork panels of the board or hardboard trim width 0.6-0.8 m, a length of 2.5-3 meters. These dimensions make it possible to produce high-quality compacting the mixture and easily rearrange the formwork from place to place.It is necessary to have multiple sets of boards.The more, the faster the filling, because the less time spent waiting for a solution to the readout setting formwork .
Simultaneously with shields fabricate boxes to fill the doors and windows.
Fix the boards on the foundation.The desired thickness of the wall is ensured by wooden or steel spacers inserted between the boards.Contractible panels together conveniently using binding wire, threaded through the shields and twisted by a crowbar.Wire harnesses provide sufficient astringent effort, not allowing shields bursting under the effect of the solution.When parsing formwork they remain inside a wall, cut off only their projecting ends.Secure the formwork box door (or doors if there are several).
During the installation of the first row formwork its stable position relative to the foundation provided by thrusts, delivered on both sides.In the future, the role of the lower thrust and locking element will carry the wall itself.Bottom panels will cover it on both sides, and the wire harness is firmly dragged boards to the walls.By installing formwork, every time check its verticality with a plumb line.
Set formwork reinforcement.When pouring monolithic walls of lightweight concrete, it is a must.No need to install it too often, but it must have a vertical and horizontal communication, fastened with wire.At the corners lay the bent reinforcement rods that will bind the wall together.
Bring ready-mix concrete or prepare it yourself.The ratio of components in slag and keramsit take 1: 3: 7 (cement: sand: slag) and 1: 3: 6 (cement: sand: expanded clay).In preparing or ordering solution count necessary amount on the basis of their established presence formwork .
Pour the solution into the formwork and well compacted it - vibrators, shovel or other tool until no more air bubbles and the formation of a smooth surface of the water layer.After pouring the next number immediately placed in a solution of vertical reinforcement bars for the next level.
After the solution acquires sufficient hardness (2-3 days, depending on weather conditions), remove the boards and set them above - to fill the next level.Do not hurry with this work, so as not to disturb the integrity of the filled wall.

Tip 2: How to build a house of permanent formwork

use of permanent formwork makes it possible to significantly increase the pace of construction of monolithic reinforced concrete.In addition, it also enables to insulate the exterior walls of the house.For this purpose lightweight polystyrene blocks.They are easily sawn and allowed to build walls of any shape.This construction does not require special skills and high financial costs.
How to build a house made of permanent formwork
you need
  • - permanent formwork of polystyrene blocks;
  • - roll waterproofing;
  • - fittings 8 mm;
  • - concrete;
  • - brick;
  • rafters;
  • - OSB-plates;
  • - roof.
Make base and lay the first rows of masonry.For example, you can use a monolithic strip foundations with plinth made of bricks.If the cap is raised from the same basement blocks, in which case the wall of the house will hang over him as a wall unit with polystyrene foam liner wider than it.Therefore, before laying lay blocks on the walls, so you save time and do not make unnecessary cuts blocks.
Put the cap on the roll waterproofing.Only then should start laying the wall blocks and poured concrete.Construction of the wall begin to install corner blocks, then pull the cord between them, which will be putting some level for ordinary blocks.Bonding between the blocks with a solution is not necessary, for that they are at the ends of the ridges and grooves.Keep the blocks (their internal cavity) of all rows of the wall had a match vertically.Ligation between the rows is done by using special corner pieces and halves blocks.
Lay one row of blocks.Place in the recesses that are at the top of the short walls of the block, rebar diameter of 8 mm in length, and twist the wire overlap.The cavity in the center, set the vertical reinforcement and tie it with the previous or with pre-established in the foundation anchors.Lay the second row of blocks, putting them on the vertical reinforcement that is sticking out of the bottom row, and then lay the longitudinal reinforcement.
Collect series 3-4, then fill the cavity with concrete vertical.Seal it by hand or vibrator.Reinstall 3-4 series polystyrene blocks, etc.The result is a monolithic reinforced concrete wall.This process can be carried out at high speed and without qualification.This technology does not require the installation of concrete bridges over the door and window openings, and there is no need to fill in a monolithic belt joists.Monolithic wall structure has a high load-bearing characteristics.
Install soffit.You can put slabs, beams and floor joists, for that in the blocks, which will be designed for this cut before pouring concrete ΒΌ of the opening and make styling.Spend engineering communications.Permanent formwork technology allows to construct buildings of all shapes and configurations.Therefore, communication is usually used for internal voids in the blocks.
Install roof.Truss does not have any features.Make them a solid floor from OSB-boards, secure the perimeter drains and place, for example, soft shingles.Oshtukaturte walls, insert doors and windows, floors paved.Consumption per 1 m2 concrete wall is between 0,075-0,125 m3.
cavities of the top row of blocks fill up to half to cool the seam inside.
Helpful Hint
Before filling the walls can be laid out in brick basement.This will positively affect the appearance of the home.But you can do without the cap, its function is to perform bottom-drenched walls.In this case, it must be vented.

For protection against atmospheric effects of aerated concrete walls plastered or sheathed with any moisture-resistant material.
