Permanent formwork for the foundation with his own hands

Fixed timbering for the foundation builders used more than 15 years.They assessed the Universal Rapid technology for the construction of the foundations of large industrial, residential and private buildings.The main advantage of this method is to minimize poor quality of work, a factor of the physical process and human intervention.Made polystyrene formwork blocks for performers require precision assembly composed by drawings.

Advantages and disadvantages of permanent formwork

application of the formulation does not change the basic process of pouring the foundation, they affect the duration of the work, reducing the time.Classical technology offers this procedure works:

1. acquisition of material on formwork.
2. assembly construction at a construction site.
3. fence installation in a specially dug ditch.
4. pouring concrete-cement mixture.

The fixed form of offers to assemble pre-engineered enclosing barrier and install it into the trench.

advantages of fixed bases:

1. non-flammable, have fire safety category T2.
2. assembly does not require time and special knowledge in the design.
3. Earthquake resistant strengthen the foundation blocks vertically.
4. Low density blocks does not overload the construction of the foundation.
5. assembly does not require special equipment.
6. moisture repellent material.It creates additional protection.
7. not contribute to the development of micro-organisms and fungi.
8. Protects from the cold.
9. Reduces the construction of the foundation stage of 5 or more times.

technology Disadvantages:

1. Fixed timbering is intended for single use only.

composition of the material for permanent formwork

1. Standard - polystyrene.Thermal insulation, moisture repellent, lightweight material.Produced by domestic manufacturers.formwork cost $ 1 per linear meter.

• advantages of the material: fire-sale price.Additional thermal insulation of walls;
• shortcomings: brittle, it has a low air permeability.

2. Blocks of a mixture of wood chips and cement - arbolit.For reliability and durability of wood chips processed chemical compounds that increase protection against vlagovpityvaniya, rot and fire.The special structure of the material is achieved by a chaotic arrangement of air fields around the tree.

• building material advantages: high sound and thermal insulation capacity.Used for pouring the foundation and floors;
• shortcomings: not an ideal surface roughness may or small recesses.

3. fibrolitovye blocks.Made of a mixture of alkali magnesite, Portland cement and wood shavings.These blocks are environmentally friendly, without harmful chemical additives.

• advantages of the material: bioustoychiv, frost, endowed with high characteristics of water vapor permeability, durable, fireproof;
• flaw is not popular, rarely used due to the nature of the production process.

4. Patented "rolled concrete" - the best solution for low-budget construction.The principle of the process is simple and allows you to produce your own form of ordinary and complex configuration.In the production scale to produce rolling mills and tables using rollers and templates.Use a special mold, which makes it possible to pour any offbeat or thin shape with a complex profile.Inside lay the reinforcement establish mortgages and locking rolling elements.It is possible to produce light-gage products of complex profile determined the use of the method for the production of a lightweight shell of permanent formwork.At manufacturing cement, water and sand.Do not apply seals and plasticizers.

• advantages of the method: the production of complex components Thin.

unique material properties: high resistance to frost up to - 500C, is not destroyed in climates with extreme temperatures and high humidity, is resistant to aggressive environments.The only material for permanent formwork, which allows to give an aesthetic look outside.This is achieved through the addition of mineral wool, basalt, marble chips, mineral dyes or pigments.

Fixed timbering for the foundation with his hands

With careful and precise manufacture of permanent formwork sets at home.

materials and tools required for the process:

• Buy sheeting that meets the requirements: resistance to decay, elasticity, strength.The selection is made from plywood, impregnated with a special compound, DSP sheets, flat slate.
• Buy reusable formwork kit consisting of retaining screws and nuts.
• Prepare a stock of cement, sand, water fills the basement.

• Procure reinforcing bars.
• Buy waterproofing material.
• mineral insulator.
• vibrator.The working part of the machine up to 40 mm.Reinforcement or a piece length equal to the block height increased by 3 times.

technology foundation for the construction of permanent formwork:

1. basement Ground covered with waterproofing.
2. hammered reinforcing bars in the foundation of the foundation.The distance between the rows is chosen from its own calculations with a stock on the thickness of the mineral wool.
3. on reinforcing rods put blocks.
4. Lay the first layer.The grooves are placed horizontal reinforcement.The clutch produce overlapping produce wire bind the connection between fragments of the reinforcement tabs and the main vertical reinforcement.The first layer - the main.In accordance with the construction plan at this level are placed outlets for internal partitions, door slopes.
5. Fix form permanent formwork for laying the second layer of blocks, providing overlapping seams.Keep an eye on the coincidence of the sides of each layer.The process is similar to laying bricks masonry.Also performed a number of displacement, providing the rigidity of the walls.
6. Connect the blocks in the vertical grooves on the surface of the form.To close enough lung pressure.
7. Perform stacking the third layer of permanent shuttering.Align vertical joints.
8. Getting concrete pouring.Carefully fill voids and seal solution.For sealing use the vibrator or manually impel and pressed a solution expelling air pockets a piece of rebar as a bayonet.

To build strong walls, the top layer of fill half blocks, then stitch in a monolithic concrete will be inside the Styrofoam.

carrier characteristic wall depends on the grade of concrete and reinforcement class.

Raising monolithic wall immediately points the way laying of utility pipes and electric cables.Do not forget about ventilation, pre-puncture the hole blocks and carry out communication and wires prior to pouring.

Ready design with permanent shuttering looks like a sandwich: polystyrene foam placed between the concrete monolith.The spitting image of the original walls have a high rate of thermal conductivity and do not need additional protection.

Fixed timbering for slab foundation

most reliable, but at the same time, the foundation is expensive tile.Most often it is called floating.For its production requires a large consumption of high grade materials: concrete, steel framework.It poured for non-cohesive or heaving soils, if everything else is impossible under the house foundation.The thickness of the multi-storey house for aged not less than 250-280 mm.For private two-storey structure is allowed thickness of 200 to 210 mm.The density of reinforcing the foundation is not allowed below 100 kg / cu.Under the foundation laid sand and crushed stone pillow each thickness of 100 mm-150 mm.

Increased demands on the stability and reliability of the foundation slab impose certain requirements on the use of permanent formwork.For slab foundation professionals are advised to use only fibrolitovye or cement-bonded blocks.They allow you to create complex shapes with curved segments or bay.Fibrolitnaya permanent formwork for the foundation.Price from $ 0.1 up to $ 2 per square.m.

installation technology slab foundation begins with the digging of the pit, and the walls are aligned vertically.This is the main requirement of ensuring proper follow-up construction walls.Fixed timbering also set the levels and surveying instruments in the vertical and horizontal planes.Stacking produce rows, simulating masonry.Carefully align the vertical joints and placed in a bonding armature slots.

Run the installation of permanent formwork for the slab foundation of their own - a very complex process that requires the owner of knowledge in the field of planning and construction.

Fixed timbering for the foundation.Reviews craftsmen professionals

Housing Project foundation 11.6h11.6 m, with an average bearing wall.Height 1.8 m foundation. The earth 1.3 m and 0.5 m on the surface of the cap.The foundation is designed for frost-land, with heaving soils of humus and loam.The method of construction of injection into the land + permanent formwork of Penoplex.

Drawings for Constructio home users to order in a private company, offering services in the Internet space.

Construction was carried out in an area where everything developers pour concrete into the ground and used formwork.It was decided to do in the land of permanent shuttering of extruded polystyrene foam at the price of $ 0.1 per square meter.m. above the ground, it was decided to perform a low shuttering of boards for the cap.To land there were two versions of the concrete casting.First with the roofing material was immediately rejected: does not lie flat array, do not hold moisture.The second option - a foam.The benefit to the durability of the material, it has a service life of 15-18 years.And the material rejected because of the mice.They live well in it, gnaw passages and make yourself warm mink.For rural areas in the mouse housing - this is a disaster.As a result, the attention attracted extruded polystyrene.Its advantages:

1. durability.
2. not fragile, does not crumble.
3. has high thermal conductivity properties.
4. Not suitable for housing of small rodents.

The only drawback of the material:

1. cost exceeds the price of foam 3 times.

analyzing Epps prices to the price of production of formwork height of 1.9 m from the board with a 50 mm thick, have found that the extrusion material is cheaper and in the process save money on insulation.

Another factor in favor of Epps was that the foundation walls of poured straight, which means that in the spring the soil afloat will not cling to it.

Outcome:

1. hand dug trench.Wall immediately gave the maximum smoothness and vertical match for precise and correct installation Epps blocks in the ground.
2. At the bottom of the trench around the perimeter of the pad poured out of the sand (it is free in the area).Pillow Height 200 mm is selected.Sand pre-moistened and then laid and rammed into the pit.The purpose of bookmarks - leveling floor.
3. Top laid on a sandy base polyethylene film 200 microns.Joint glued shut.The film was intended to save the laitance and to give additional strength concrete.
4. put roofing felt on top.Overlapped at the joints.To facilitate the mating fittings and movement across the bottom of the trench.
5. Next set blocks of permanent formwork as described.
6. poured concrete mixture.
7. set an upper cap for wooden formwork.Installation sheets Epps made inside a wooden upper casing using screws.

Beginning of casting produced 15.06, completion of works 23. 08.

difficulties faced by the developer:

1. Dig a trench must be as early as possible, namely as soon as the local land allows you to dig.In the summer of showers work not only be suspended but also deteriorate.The bottom of the trench is stored garbage, the walls washed out with water.
2. Hiring part-time workers spend the winter.During the season it costs several times more expensive, at best.At worst, just run out of workers.
