1, floor tile usage: (Note generally different room type loss rate is different about 1-5%)
The amount per 100 meters = 100 / [(block length + gray seam width) × (block width + gray seam width)] × (1 + loss rate), for example, the use of retro tiles specifications 0.5 × 0.5M, patchwork width is 0.002M, the loss rate is 1%, and the required number of blocks for 100 square meters is: 100 square meters. Usage = 100/[(0.5 + 0.002) × (0.5 + 0.002) × (1 + 0.01)] It is equivalent to the total price of 401 tiles = number of tiles × floor tile unit price
2, the amount of ceiling
Roof plate usage=(length-shield length)×(width-shield width) Calculate the amount of PVC plastic ceiling, for example, in the net size area. The unit price of the PVC plastic plate is 50.81 yuan per square meter, the length and width of the shield are both 0.24M, the length of the canopy is 3M, and the width is 4.5M. The dosage is as follows: the amount of the ceiling plate = (3-0.24) x (4.5-0.24). Equal to 11.76 per square meter
3, package door dosage
Package door material usage = door outer frame length × door frame width, for example (as shown in the picture) with composite wood package door, door outer frame length 2.7M, width 1.5M, then its material usage is as follows: package door material dosage = 2.7 × 1.5=4.05 square meters
4, wallpaper usage
Wallpaper Usage = (High - Shielded Length) × (Width - Shielded Width) × Number of Walls - Door Area - Window Area (For example) Wall Area is calculated as net size, shield is 24CM, wall height is 2.5M, width is 5M, Door area of ​​2.8 square meters, window area of ​​3.6 square meters, the amount is as follows: wallpaper usage = [(2.5-0.24) × (5-0.24)] × 4-2.8-3.6 about equal to 36.6 square meters is part of the material The calculation of the quantity, based on the amount of material used to decorate each part, is multiplied by the respective unit price, and the total material cost of the decoration project is obtained.
5, floor dosage: (solid wood)
Longitudinal usage = room length / length of floor tile Lateral usage = room width / width of the floor tile If you encounter endless, use the carry method, do not round, but less than half of the longitudinal calculation half, more than half a block. Total floor price = total usage × unit price floor loss = floor area - floor area floor loss rate = floor loss / housing area Note: General floor wear rate is not more than 5%
6, the amount of wall material
After determining the color variety of the wall material, the size of the material can be reasonably calculated according to the size of the living room. Considering the possible loss during construction, it can be purchased with about 5% more than the actual amount. There are two ways to calculate wall materials:
1. Calculated by the formula, the area of ​​the room is multiplied by 2.5, and the product is the number of materials used for the wall. Such as 20 square meters of room materials used for 20 × 2.5 = 50m. There is also a more precise formula: S = (L/M + 1)(H + h) + C/M where: S - length of wall material required (m) L - deduction of windows, doors, etc. The total length of the rear wall (m) M - the width of the wall material (m), plus 1 as the margin of the mosaic pattern; H - the height of the desired wall material (m) h - on the wall material The distance between two identical patterns (m) C—the area of ​​the wall required for up and down windows, doors, etc. (square meters)
2. On-site measurement, this method is more accurate, first understand the width of the wall material to be selected, measure the perimeter of the room wall (excluding doors, windows, etc.) according to the width, there are several wall materials in the perimeter Width, that is, a few stickers. Then measure the height of the wall that should be affixed. Multiply this by the number of walls, which is the length (in meters) of wall material required for the wall outside the door and window. Finally, the length of material required for the wall under the window, irregular corners, etc. is measured by this method, and it is added to the calculated length, which is the total length. This method is more suitable for fine-grained patterns, without special alignment of the wall material when splicing.
7, coating amount estimation method
A simple calculation method is introduced: the room area (square meter) divided by four, the height of the wall to be painted (in decimeters) divided by four, the sum of the two is the number of kilograms of paint required. For example, a room with an area of ​​20 square meters and a wall height of 16 decimeters (except for 12-millimeter wall skirts), then, is (20÷4)+(16÷4)=9, ie 9 kg of paint can be painted on the wall two all over.
