Types and their insulation - requirements for construction + Video

When constructing various buildings, it has become popular to use screw piles, they also have. Screw piles are made from a steel pipe that has been treated with a special compound.

This composition makes piles more resistant to corrosion .

This type of piles allows you to build a house with your own hands in a fairly short time.

Next we will talk about the characteristics of houses on screw piles.

About the piles for the foundation

Below the piles there are blades, they have the shape of a screw.

Types of form

For the foundation, there are three types of piles, more about them - below.

Screw piles

They have screw blades, this type of pile is used where the bearing capacity of the soil is poor. A large number of Screw Piles have a cutting element that cuts the soil when the pile is screwed into the ground.

This type of pile is also suitable for the soil that freezes all the time.

Piles with different pipe diameters

The diameter of the pile pipe will determine its weight and ability to withstand enormous loads. Indeed, when choosing these piles, you need to focus on the entire mass of the building and in relation to this indicator you need to choose the diameter of the pile. For piles with a diameter greater than 10 cm, special equipment will be required.

Blades having a difference in diameter on one pile

If the soil is very wet, then the diameter of the pile blades is made larger.

Piles also have differences in shapes and types. This data depends on manufacturers and materials.

Types of tip

So screw piles are divided by tip type, and they are :

1. welded;
2. cast.

Welded

The option is considered cheap and economically feasible, because it consists of a pipe with a blade welded to it. Such piles are not of very good quality and for this reason, welded piles are not used in the construction of mass structures.

Such piles are used for the construction of garages or outbuildings. If the blade on the pile is not well welded, then during operation, it can move away from the vertical axis and therefore the foundation loses its durability.

Cast

Piles that have a cast tip have good strength ...

They are used for the construction of residential buildings. To make a molded tip, an injection molding method is used. The pile blades are about 12 millimeters thick and about 30 centimeters in diameter.

To make a pile shaft, take a steel pipe with a tip. Cast piles have good bearing capacity, they can withstand loads of more than five tons or more.

Of course, the cost of a molded tip is slightly higher than that of a welded tip.

Types of coverage

Piles also differ in the type of coverage. Steel is sometimes treated with an anti-corrosion agent and sometimes with a polymer coating.

When buying piles on the market, you must familiarize yourself with the certificate of conformity with the factory norms and all standards.

Because there are a huge number of fakes that do not differ in any way from real piles.

There is also a variant of piles for the production of which thick-walled pipes are used. In terms of reliability, such piles are on the same level as cast piles. Piles provide a solid foundation for large structures.

Pros and cons of screw piles

Pros of screw piles and their advantages :

1. Fast foundation construction;
2. No need to wait for foundation construction;
3. Screw piles are easy to install .

   Piles can be installed by hand, but if the size of the piles is large, then you need to hire special equipment;

4. Affordable price;
5. Can be used on various soils;
6. Does not require preliminary leveling of the site ;
7. Good resistance to loads;
8. Long service life;
9. Does not require excavation.

Disadvantages of screw piles and their disadvantages :

1. If you chose low-quality piles, they quickly come out of standing and lead to uneven subsidence of the structure;
2. If the soil contains a large number of stones, then the installation of piles will be difficult;
3. The need to follow the rules of installation and technology.

Frame house on screw piles

When the process occurs the construction of a frame house, screw piles are often used.

But this does not require hiring specialists, it is enough to hire a certain number of people.

Screw piles must be installed vertically.

If the pile is screwed in incorrectly, then it should not be pulled out and screwed again.

Construction technologies

There are two technologies for building a house on screw piles :

a). Finnish;

b). Canadian.

Requirements for the construction of frame houses

They are identical and we will voice them further.

1. To build the frame house , you need to use separate frames. To make them, steel and wood are used, as well as timber. Timber frames are considered environmentally friendly, easy to install and safe. Steel frames are slightly more expensive than wooden structures.

   But the weight of metal frames is an order of magnitude lower than wooden structures, and therefore the metal structure does not exert much pressure on the base. To connect wooden structures, pins are used, and the rest of the frames are fastened together with steel parts.

2. Houses on stilts are made of timber. First, with the help of roofing material, waterproofing is equipped, and then the timber is installed. Before laying the subfloor, logs are made and insulation is mounted inside.

   Before laying, the boards must be treated with an antiseptic. You will choose the insulation for the floor at your discretion, taking into account the climatic features of your region.

3. After you have finished installing the floor , you can start installing the walls. The walls are assembled on a flat surface, then they are installed in place. You must not allow distortions when you connect the frames to each other.

   Jibs are used to support the racks of the frame wall.

4. When you install the walls, be sure to take into account the height of the ceilings in the rooms. The optimal value for ceilings is 250 centimeters.
5. Wall cladding is carried out after installation of the frame, doors and windows are also insulated.
6. Then the roof is installed and finished.

   Then make the exterior and interior decoration of the walls of the house . After that, the interior and exterior decoration of the walls of the house is done.

Warming

To it was possible to live in a frame house in both cold and warm seasons, it is necessary to insulate it. Before you start insulating your home, you need to decide on the type of insulation.

It is best to carry out insulation outside and inside the building.

To insulate the house from the inside use drywall and mineral wool.

Before starting the final finishing of the facade, it is necessary to insulate the outside of the house on screw piles. First, a crate is made of timber on the walls of the house, then mineral wool or other insulation is laid.

To seal the gaps between the heaters, polyurethane foam is used.

It is also necessary to equip wind protection, waterproofing, because mineral wool is not resistant to moisture.

All rooms of a frame house must be protected from condensation, and especially such rooms as a bathroom and a kitchen. A special membrane is used as a protection against condensation, while at the same time it brings the condensate out.

Since frame houses are built mainly from wood, you cannot use a film as thermal insulation, but it is best to use a special membrane. If you follow all the technologies for the construction of frame houses, then it can last for quite a long time.

The base of a house on screw piles

To close the space between the piles and the floor, take the following steps :

1. Wooden or steel guides are installed on the piles; they are fixed with self-tapping screws.

   Then do the installation of sheet material and then make the final finishing of the ebb.

2. Shallow strip foundation. Concrete is poured into the trenches, which are made along the perimeter of the screw piles. Cinder blocks are laid on such a foundation or brickwork is made.

In this text we have told you how to build a house on screw piles. We hope this article was helpful to you. We wish you the best of luck!
