1, floor tiles
A rough calculation method:
Room floor area ÷ Area of ​​each floor tile × (1+10%) = number of bricks (where 10% means increased loss)
Accurate calculation method:
(Room length ÷ brick length) × (Room width ÷ brick width) = number of bricks
5m long and 4m wide room, 400mm x 400mm
Take the standard floor tile as an example:
5m÷0.4m=12.5 blocks (take 13 blocks) 4m÷0.4m=10 blocks
13 × 10 blocks = 130 bricks in total.
When purchasing, additional loss of about 3% -5% is required.
2, wallpaper
Common wallpaper specifications: Each roll is 10m long and 0.53m wide. → Related Links: Wallpaper Usage Calculation
Rough calculation method:
Ground area × 3 = total area of ​​wallpaper
The total area of ​​the wallpaper ÷ (0.53m × 10) = the number of wallpaper
Accurate calculation method:
Wallpaper per roll length ÷ Room actual height = number of components used
The width of the room's circumference = the total number of units used
Total number of used units åˆ†é‡ Number of used units = Number of wallpapers used
Because the wallpaper specification is fixed, when calculating its usage, it is necessary to pay attention to the actual length of the wallpaper. Usually, the actual height of the room should be used to subtract the height of the skirting board and the top line. In addition, the door and window area of ​​the room should also be subtracted from the number of components used.
This calculation method is suitable for plain or fine-grained wallpaper. In the collage of wallpapers, the bigger the pattern is, the bigger the pattern is, and the greater the loss, so it is about 10% more than the actual amount.
3, composite floor
Common specifications: 1.2m×0.19m
A rough calculation method:
Room floor area ÷ (1.2m × 0.19m) × 105% = floor number
Accurate calculation method:
(Room length board length) × (Room width board width) = number of floor boards
Take a 5m long and 4m wide room as an example:
Room length 5m ÷ 1.2m ≈ 4.17 (block) Take 5 (block)
Room width 4m ÷ 0.19m ≈ 21.05 (block) Take 2l blocks
Total plate: 5×21 blocks=105 blocks
Composite wood floors often have 3% to 5% of the loss in the pavement. If you use the area to calculate, do not ignore this part of the amount.
4, solid wood flooring
Common specifications: 900mm×90mm×18mm, 750mm×90mm×18mm, 600mm×90mm×18mm
A rough calculation method:
Room floor area ÷ Floor area x 1.08 = floor number
Accurate calculation method:
(Room length ÷ Floor length) × (Room width ÷ Floor width) = Floor number
For a room with a length of 5m and a width of 4m, use a 750mm × 90mm × 18mm floor as an example:
Room length 5m ÷ 0.75m ≈ 6.67 (block) Take 7 (block)
Room width 4m ÷ 0.09m ≈ 44.44 (block) Take 45 (block)
Need to purchase wood flooring Quantity: 7 × 45 blocks = 315 blocks
When buying, it is necessary to take into account that 8% of the loss is usually found in solid wood floor coverings.
5, curtains
Normal curtains are mostly flat curtains. Before calculating curtain materials, the size of finished curtains must be determined according to the specifications of the windows. → Related links: Buy curtains to calculate a good way to guard against being slaughtered
The finished curtain should cover 0.15m to the right and left of the window frame and double folds. When installing curtains to be 15-20cm from the ground.
Calculation method:
(Window width +0.15m × 2) × 2 = Finished curtain width
Finished curtain width ÷ Width 窗帘 Curtain height = required for curtains
Assume window specifications: 1.55m wide and 1.90m high:
Finished curtain width = (1.55m + 0.15m x 2) x 2 = 3.70m
Curtain height = 0.15m + 1.90m + 0.50m + 0.20m (Burma) = 2.75m
Take the cloth width 1.50m as an example:
Need to buy curtain fabric: 3.70m÷1.50m×2.75m=6.78m
6, coating
The packaging of the paint is basically divided into 5 liters and 15 liters.
Taking the 5 litre capacity commonly used in the family as an example, the theoretical brushing area of ​​5 liters is 35 square meters twice.
A rough calculation method:
Floor area x 2.5÷35= bucket number
Accurate calculation method:
(Room length + room width) × 2 × room height = wall area (including door and window area) Room length × room width = ceiling area
(wall area + ceiling area - door and window area) ÷35 = bucket number
Taking a room with a length of 5m, a width of 4m, and a height of 2.7m as an example, the indoor wall and ceiling brushing area is calculated as follows:
Wall area: (5m + 4m) × 2 × 2.7m - 48.6m2 (4.5m2 including doors and windows)
Ceiling area: 5m×4m=20m2
Coating amount: (48.6m2+20m2-4.5m2)÷35 m2/bbl = 1.83 barrels. Actually need to purchase 5 liters of paint 2 barrels, the rest can be used as a backup.
The above is only the theoretical amount of brushing, because in the construction process to add appropriate amount of water, so the above amount is only the minimum amount of brushing.
