Board or timber on the frame?

Let us again go over frame structures, Yeah? It is for him as one of the most common and cost way to low-rise buildings. The question that I once set myself and now I want to ask you is:

Board or timber used in the frame?

Try to understand?

My decision in this matter clear - only the board. And the explanation as to some, let's try to sound them and discuss:

1. Facilities being equal cheaper. Everything is explained simply - if you build a skeleton of beams 150x150, it will take exactly three times as many cubic meter than the board 150h50. Obtain unwarranted cost overruns money.

2. Bruce turns the screw. Many will say that the board also turns the screw, but in the framework of a board is easier to deal with this problem.

3. Classified trite lighter timber, which means easier installation.

4. Cold bridges in the case of boards less than in the case of the beam.

You can argue that entirely without timber is unavoidable, eg, the floor joists many make it out of him. Well, Well, let's assume: first assume that the length of a lag in our 3-meter. In the case of timbers everything is simple - 3-meter rod 150x150 at one lag. But in the case with the board again is cheaper: just take the two boards 150h50 and connect them together with short inserts (3 meters they need 3 pieces of 50 cm) from the same board. That is, one lag is obtained by 7,5 meters board.

Per cubic meter up is as follows: timber - 0.0675, the board - 0.05625. Or that the numbers were poponyatnee - 10 lag, we will take timber 0.675 cube and board - 0.5625 cube. Savings obtained about 17%, or at a price of cubic meter in 6500 rubles - 1105 rubles of net savings!

The observant reader may notice that it would be necessary Yeshe and hardware to count in the case of boards on the floor beams. All right, but it's pennies compared to the cost of lumber. Kilogram of nails costs about 130 rubles, a grouse on a tree - about 3 rubles. At 10 lag enough pounds of nails 100 mm and 60 100 mm capercaillie - a fixture, even with the stock. For money is obtained about 300 rubles, which is still less than the difference in cost of timber for these same 10 lag.

Neither, finally, one more argument in favor of the boards (still lags about floor) - this construction of the united board works as a farm and get much stronger timber, considering the load. Such arithmetic here.

Good luck on the construction site!
