Before we start calculating the cubaturedifferent types of boards and answer the question: "How many boards are in the cube?" - we should consider what the concept of "cubic meter of lumber" means, and what the construction market offers.
Varieties of sawn timber and their sizes
The boards are produced by longitudinal sawing of logs.Typically, they have a length of 4 to 6 meters. The width varies. The most delicate ones belong to the class of carving - up to two and a half centimeters, then there is a board-shallevka, the thickness of which is basically equal to two centimeters (but it happens 2.5, 4 and 5 cm). More expensive - construction board trimmed, the size of which is quite standardized: the width is always greater than its double height, and the length is 4 (less than 4.5) and 6 meters. Thicker boards are called a bar. For convenience, sawn timber is sold in cubes, and for construction it is important to know how many boards in 1 cube.
We will not examine the paneling, due to the fact that this type of sawn timber is used mainly for finishing works and is calculated separately.
First of all, you will needboard-shallevka, which is several times cheaper than edging and is needed for the device formwork, hem filing, roofing, device roughing floors, construction of utility rooms.
The width of such a board can be 10-15 centimeters,in length they are standard or cut into two or three meters. Knowing the perimeter of the future foundation and the parameters of the casting, it is easy to calculate how many boards in the cube and how many cubic meters you need to buy on the formwork. For more accurate calculations, you can use online calculators that are on the site of most vendors of sawn timber.
What is considered a cubature?
If you directly answer the question:"How many boards are in the cube?" - then there will be one option - a cubic meter. We need more specific data. For example, what area can be sewn with one cube of sawn timber of a certain thickness?
Conditionally we will denote the width of the board - W, the thickness - T, the length - A. The result will depend on the thickness (T). Square formula (P) is known from the school bench:
- P (m2) = WxD / T (1 mx 1 m / 0.02 m = 50 m2).
That is, if we take a cubic meter of boards 2 cm thick, they will cover 50 m2.
Sometimes you need to know the total length (D) of a tree in 1 m3.
We calculate according to the formula:
- D = 1 m3/ T x W.
And finally, the answer to the question: "How many pieces of the board are in the cube (bars, round blanks, etc.)?". If the parameters of the lumber are known, the result can be obtained by applying the formula:
- K = W x T x D.
On this principle count and cubic capacity of one board, but do not forget to translate all the dimensions in meters.
Examples of calculating the volume of the edging board
The most popular edging board, whichIt is used for the installation of walls, floors, ceilings, partitions, rafters and stairs. Each size has even its own "name": inch, forty, five, bar (it is immediately clear what the width of the board is talking about).
Count, for example, how many boards in the cube of the inch can be, knowing its width. So, with a width of 10 cm - it's 66 pieces, and at a width of 15 cm - 44 pieces. One cubic meter is enough for a cover of 40 m2.
An example of calculating the cubature of one six-meter-long, 15-cm-wide piece:
- 0,15 m х 0,025 m х 6 m = 0,0225 m3.
If necessary, calculate the volume, for example,floorboards (with spikes) in the formula only the working width of the board (without a spike) is substituted. If the blockhouse is calculated (a board imitating a log), then the thickness is indicated at the highest point.
