Advantages of prefabricated wooden house

Advantages of prefabricated wooden house:

• Making parts in an environment outside the construction site
• High construction speed due to the prefabricated wooden house
• The lightness of the structure
• Stable and high quality
• Use of modern technology in design and construction
• The unique beauty of wood as a widely used material in the world
• No need for insulation against sound, cold and heat
• No need for facade due to the unique beauty of wood

For house construction, they are classified as lumber in three different types.

• Cut timber
• Solid timber
• Multi-layer timber

Cut timber: It is sanded wood from tree trunks, with a diameter of 14 to 42 cm, with many uses, including the external and internal walls of a wooden house, in the design of a sauna and the construction of gazebos as well as the decoration of roof gardens and terraces, etc.

Solid timber: This timber is prepared in an integrated form with different thicknesses and with multiple applications, including external and internal walls of wooden houses, construction of gazebos, roof gardens, etc.

Multi-layer timber: This timber is obtained by gluing several layers of wood and putting it under pressure. With different thicknesses and with many applications, including external and internal walls of wooden houses, construction of gazebos, roof gardens, etc., which has a high level of stability and strength.

Profiled wood:

It includes partitions, floorboards, terrace boards, Eurolining, etc., and its advantages include sound insulation, heat insulation, anti-allergy and it is used in the design of interior and exterior decoration, ceilings, walls, and smooth surfaces.

The steps of building a prefabricated wooden house

The construction steps of a wooden villa are common with other buildings. But in general, it has many differences with its similar examples. Naturally, all buildings have structural and architectural parts and facilities. But due to the fact that the primary material in the construction of our wooden villa is wood, it will naturally have differences with other similar buildings.

In general, the construction steps can be divided into several parts.

o Implementation of foundation and skeleton

o Walling and structural floor implementation (building shell)

o Implementation of facilities (electricity, pipe work and refrigeration equipment)

o Implementation of floor and ceiling and exposed surfaces (Expose) and installation of windows (finish)

o Installation of refrigeration and facilities equipment (valves, radiators or split ducts, outlet switches, etc.)

Foundation:

For the implementation of the foundation in wooden structures, due to the fact that wooden structures are lighter than concrete structures, it will play the role of a seat to keep the structure higher than the ground during rainfall and water flow. There are different types of foundation, which requires an examination and expertise from the project site to determine the best type of foundation for each project.

In this topic, we introduce the most common type of foundation for wooden houses.

Pile foundation:

For the construction of a wooden house, which does not have a basement or ground floor, pile foundation is the best option. It should be noted that the construction of a pile foundation will be the best solution if the soil is weak and there is a serious slope in the construction site. Also, one of the important factors that make the pile foundation preferable is the presence of underground water near the support base.

Concrete slab foundation:

Concrete slab foundations have high mobility where the soil is very unstable and are generally considered unsuitable for construction. Concrete slab foundations are like one big monolithic board. This type of supporting foundation can save the house from subsidence when the ground moves.

Strip foundation:

Strip foundation is one of the most common types of wide and usually shallow foundations. These sections are usually made of reinforced concrete and are used in the form of a wide strip around the building and in loose soils. Strip foundations are responsible for transferring the load to the ground.

It should be noted that due to the light weight of wooden skeletons, if there is subsoil with suitable compressive strength, prefabricated concrete parts can be used instead of wide or strip foundations.

Another type of foundation for wooden huts includes foundations and columns called pedestals, and a metal plate is worked on it and the skeleton is installed on it.

  The height of the pedestal depends on the terrain or the desired height of the client, and the seat will be adjusted to the level of the pedestal.

The design of a wooden house, like any other house, is done with a design that fits the needs and wishes of the customer.

First, a preliminary design including floor plans, facades and sections is prepared, which shows all the sizes and details of the spaces. After the approval of the preliminary design by the engineering system, all the architectural, structure and facility plans are prepared in detail along with the plan. Assembly is provided for manufacturers.

The assembly plan shows the thickness, dimensions and number of related timbers along with their markings.

The length of timber related to wooden houses is at most 6 meters. Therefore, if the walls of the house are longer (probably this happens), the timbers are connected together.

Connections should be planned in places where the main walls are connected to the interior walls. This prevents unnecessary heat loss.

Wooden house assembly:

At the beginning of assembling the house, attention is paid to the size, design and position of windows and doors. Special attention should be paid to the quality of assembly: connections and seams, matching the size of windows and doors with openings, etc.

Before use, all logs must be coated with fire retardant material.

Timber connection:

Several methods are used to fasten wall timbers – mechanical fastening and gluing, the use of mechanical fasteners include bolts and nuts, drift pins, lag screws, wood/timber screws and nails. Gluing is done by placing a bead of mastic or sealant product along the length of the log.

The most common wood fasteners are wood screws. Long screws that can be set quickly and easily with an electric drill. In order to install them, there is no need to drill a hole in advance. Therefore, the speed of using them is high.

Typically, roofing and flooring are done after the roof is finished. At the time of assembling, it is very important to follow the project carefully, because failure to do so, may cause the roof to sag or even fall. After assembling the beams, covering layers, moisture and thermal insulation and the roof itself are placed.

After the floor and ceiling are installed, stairs are built, windows and doors are installed and walls are coated with special solutions to protect against fire, bacteria and insects. From this moment, the housing can be considered almost ready.

Electrical wiring must be chosen with double insulation and placed in a metal hose and hidden in special grooves cut in the log and covered from the outside with tape or plinth so that nothing can be seen in the appearance of the work. It should be considered that the structure of the house shrinks and mechanical impact on the metal hose should be avoided. To solve this problem, the grooves should be made with a margin of 2-3 cm. In another way, by placing in special boxes, in case of short circuit or overvoltage in the network, the power will be cut off automatically.

Implementation tips:

You should always pay attention to several points when building wooden structures. One of them is to pay attention to the direction of timber loading, because the narrow tolerance of the wooden structure is basically determined by loading across the texture path or parallel to it, which should also be mentioned in the executive plans.

Another point is to pay attention to the type of wood used. Because in case of lack of quality or moisture inside the timber, the stability of the building will be questioned. In general, the timber made from trees whose growth period is long has a higher quality. The pine tree is one of these trees that has suitable timber for building wooden buildings.

Another important point is to pay attention to the displacement of the wood due to the increase or decrease in volume due to contraction and expansion, which can be solved by creating a distance between the timbers and by placing small wedges (such as screws or thin plastic pieces). It can be fixed between the timbers.
