Construction of a 6x4 garage, how and from what to build, how to calculate the number of blocks

Before the construction of the garage is started, important preparatory work is carried out. The article describes the construction of a garage 6 to 4, the choice of method of construction - as an extension or a separate structure. The following material discusses the types of building blocks, their pros and cons. You will learn how to prepare for the design and calculate the number of foam blocks.

How and from what to build

Most owners of private plots are eager to get a garage first of all, which is not surprising, given the climatic conditions in a large part of the country. Garages are built in two ways: in the form of an extension to a residential house and as a separate building; each option has its advantages and disadvantages.

The garage adjoining the house is more economical in construction: because of the common wall, the consumption of building material is reduced, it is easier to equip the garage extension with communications and alarm systems. Inside you can get through the adjacent door without going outside (which is especially nice in rain or frost). The downside of the attached structure is the noise and smell of gasoline entering the premises; besides building an extension is not always convenient.

An alternative, detached garage is a much broader solution. Its dimensions are determined by the dimensions of the iron friend; For most cars, a 6x4 garage will be an acceptable option. In the construction of this size there is a place not only for the machine, but also for the tools (and, possibly, for a small workshop).

Garage extension to a residential house

There are many building materials on the construction market that are suitable for building a garage, including corrugated and silicate bricks . The most popular options are block materials made from various raw materials. Their main advantage is the large size of the blocks, which allows to speed up and simplify the process of laying.

Types of block materials

Compared to brick, large blocks have a number of indisputable advantages: they cost less, reduce construction costs (for example, masonry consumption) and reduce construction time. Most often, the following types of building blocks have been used for the construction of a garage 6 4:

Slag stones

For more than 20 years, the cinder block has been a popular material, practical and inexpensive. This kind of artificial stone, in which a diverse filler (slag) is bound by cement, is obtained by vibropressing. Brick or concrete crumb, glass breakage, ash, expanded clay and other available materials can be used as a filler.

Walls of cinder blocks

The components in the composition determine the characteristics of the slag blocks, including the following parameters:

  • Weight . It depends on the voidness, which is measured in percent, from 0 to 50% (0% - full-bodied, the most severe). In any case, the garage will need a solid foundation.

  • Standard dimensions are 390x190x188 mm.

  • Slag stone refers to non-combustible materials and is not subject to shrinkage.

  • Practicality in operation : the material is strong and durable.

  • Disadvantages . These include a weak level of sound absorption, hygroscopicity (the unit absorbs moisture) and high thermal conductivity. This forces to insulate the walls, as well as to carry out external finishing (plastering or covering with facing).

Aerated concrete blocks

A significant amount of aerated concrete block is occupied by closed and open spaces filled with air, which gives the material the following properties:

  • Low weight and density . The walls of aerated concrete do not load the foundation like a brick and reduce not only the time of construction works, but also labor costs. The material is not suitable for the construction of multi-storey buildings, but in private construction is used with success.

  • Moisture resistance . The material has a certain hygroscopicity due to the fact that not all air cells in the block structure are isolated from each other; walls require protection from moisture and freezing (they must be insulated).

  • Energy Saving . Heat insulation indicators allow the use of blocks in any climate.

  • Operational parameters . Aerated concrete has exact dimensions and is easy to process, it is fire resistant and it well withstands freeze / thaw cycles.

Foam blocks

Foam concrete, like aerated concrete, belongs to the group of cellular concrete, which determines its properties. Foam concrete blocks are widely used in private construction due to their advantages:

  • Construction advantages . The small weight of blocks allows to do without construction mechanisms; they do not shrink and are easy to handle. Popular sizes are 400x200x200 and 500x300x200 mm.

  • Attitude to moisture . Features of the structure of foam concrete - closed air cells. This provides better moisture resistance compared to aerated concrete, but, at the same time, is the cause of low vapor permeability of the walls. They can not provide natural air circulation, which affects the indoor climate (more important for residential than garage construction).

  • Thermal insulation . Thermal insulation properties are influenced by the density of the material - the higher it is, the lower the wall's ability to hold heat. In general, foam blocks are high-quality insulating material. Wall thickness of 400 mm does not require the use of insulation.

  • Strength . Foam concrete is distinguished by its ability to increase the brand strength during operation (twice in the first 10 years).

The disadvantages of foam blocks include the need for exterior finish (plaster or ventilated facade), as well as restrictions on the choice of dowels for wall mounting. In addition to these block materials in the construction of garage walls use clay blocks, arbolitovye and gas silicate blocks, combining the budget cost with suitable technical characteristics.

Analysis and design of the garage structure

Pre-planning is an important step in the construction of the garage, allowing for an analysis of the consumption of building materials, and, therefore, adjusting the budget, avoiding unnecessary costs. Creating a project, pay attention to the following factors:

  • The choice of design . It may not be necessary to have a standard garage, but to build a larger area for one car (6x4), or for two cars (7x6), or with space for a home workshop. Often, a two-car garage is supplied with an attic, which is very practical, especially in a small area.

  • Soil features . The location of groundwater and the depth of freezing can affect the choice of foundation.

  • Additional functions (garage equipment 6 to 4). The necessity of the inspection pit and basement for home conservation is determined. It is also useful to calculate the size of the tool racks in advance and determine if you need a special work area with a workbench.

  • Material selection . The building must meet many criteria: to reliably protect the car, to have a long service life and to be inexpensive in construction. The foam block has a combination of these qualities, which allows you to quickly build a practical and inexpensive garage.

  • Dimensions of the structure . The average garage building has a height of 2.4-3 m, a width of 3-4 m, a length of 4.5-6 m. Based on these parameters and the standard size of the selected block, the required amount of material is calculated.

  • Calculation of estimates . Conducted taking into account the design features, the cost of connecting electricity and water supply, the amount of materials needed, transportation costs.

  • Design subtleties . The weak side of foam concrete is low vapor permeability, which can cause condensation. In order to maintain a comfortable level of humidity in the room, you should take care of the ventilation system (natural or forced).

Calculation of the number of foam blocks

For erection, it is convenient to take foam blocks with dimensions of 600 * 300 * 200 mm. When using this material, the wall thickness can be set to 200 or 300 mm, placing the block in different ways relative to the wall plane. The thickness of the garage walls is usually set equal to 200 mm.The approximate calculation of the number of blocks for a garage of 6x4x3 m in size (as well as a garage of any size) is performed according to the following scheme:

  • Calculation of the perimeter of the garage construction: (6 + 4) * 2 = 20 m.

  • How many blocks will fit around the perimeter (in the same row): 20 ÷ 0.6 = 33.3 (round up to 34 pieces).

  • Determining the number of rows (by height). With a given height of 3 m and a selected block height of 300 mm, we get: 3 ÷ 0.3 = 10 rows.

  • Preliminary determination of the total number of blocks: 34x10 = 340 pieces.

Blocks are calculated taking into account openings
  • Accounting for openings . In fact, less material is needed, because there will be gates in the garage and, possibly, doors and windows. About 6 blocks are placed on an area of ​​one square meter (if the thickness of the walls of your garage is 200 mm). Knowing the dimensions of all openings, you determine the area of ​​each (by multiplying the length and width), determine the sum of the areas and multiply it by 6. The result lies in the interval between 40 and 50 blocks. Subtract it from the total and get the total number of 290-300 blocks.

  • Nuances . Usually, another 5% (in this case, 15 pieces) are added to the calculated quantity for two reasons. First, the calculations did not take into account the thickness of the seam; secondly, an amendment is made for the carriage in which damage to the edges of the blocks cannot be excluded.

  • Options . Many believe that the optimal height of the garage 4x6, suitable for most cars, is 2.4 m, which is: 2.4 ÷ 0.3 = 8 rows. This allows to reduce construction costs somewhat.

Foam blocks are a frequent choice for building a garage, because they have an optimum set of characteristics for low-rise construction and allow you to build a structure that reliably protects the car. Although the technology of construction work is considered to be simple and low-cost, the design and construction of complex construction (with an attic, hozblok, liner engineering communications) should be entrusted to the specialized organization.
