How to Calculate Roof Roof Building
Calculating the volume of the roof building will also indirectly calculate some parts of the building that is located at the top of the building position. In this case to note is to determine the type of roof truss material to be used. Currently looking for material from wood is relatively expensive, especially for certain types of wood that has resistance to termites so that most housing bertipeminimalis tend to use roof framework made of mild steel.
The different types of materials will also determine the methods used in calculating the roof volumes. Lightweight steel roof truss work is calculated in temporary m2 units for wooden roof frames calculated in units of m3. By the time you count the top of the building you are counting are roof truss, roof cover (tile), list plank, gutter and roof ridge. Since it is calculated in units of m2 then usually the lightweight steel distributor has calculated the price including with the gutter of water so that later you simply calculate the area of ??the roof frame only.
Calculating lightweight steel roof truss means it includes calculating the area of ??the top cover as well, so the calculation method is relatively faster and easier compared to calculating wood-based roof truss. However, what needs to be taken into account again is the type of roof cover that will be borne by lightweight steel roof truss. It is very important to note and ensure that there is no overload borne by rangkaatap as it will affect the strength and age of the roof.
To calculate the area of ??roof truss with lightweight steel-based material that is by using the formula:
V = (PXL) / Cos a
There are various approaches to calculate the roof, can with trapezium hanging the easiest according to you.
Example:
The roof corner = 30 degrees
Cos 30 = 0.866
For example:
L = 18 × 11 / 0.866 = 228.6m2
L2 = 1.2 × 5.08 / 0.866 = 7.039m2
Total = 235.7m2
Information:
V = Area of ??roof truss (m2)
P = Roof length of flat condition (m)
L = Flat roof width (m)
a = The angle of the roof (degree)
From the calculation of lightweight steel roof truss above it indirectly you can know the needs of the roof cover is 235.7 m2. If the roof truss uses lightweight steel, then there is no need to calculate the cost for the gutter whose position lies in the jurai meeting, since usually the lightweight steel frame order already includes the gutter. But if there is addition of gutter at the end of tile then you need to renegotiate with light steel distributor. For roof covering of a rainbow tile then the area you count has been included in the tile ridge so you do not have to recalculate it except for certain types sometimes there is a difference to the ridge part. As for the type of cover made from ordinary tile or ceramic tiles then you need to count also the number of tiles bubungannya. May be useful.
