Some calculation formulas for decoration costs 1. Floor tile usage: (note that the loss rate of different rooms is generally about 1-5%) 2, ceiling usage: 3, package door dosage: 4, wallpaper usage: Cost decoration budget knowledge calculation formula room window paint wallpaper floor tile brick Sampling Valve,Beer Sampling Valve,Spiral Type Samplevalve,Sanitary Sampling Valve Ningbo Wenhan Fluid Equipments Co., Ltd. , https://www.wenhanvalves.com
The amount per hundred meters = 100 / [(block length + gray seam width) × (block width + gray seam width)] × (1 + loss rate)
For example, the size of the retro floor tile is 0.5×0.5M, the width of the joint is 0.002M, the loss rate is 1%, and the required number of blocks for 100 square meters is:
100 square meters = 100/[(0.5 + 0.002) × (0.5 + 0.002) × (1 + 0.01) approximately equal to the total price of 401 tiles = number of tiles × number of tiles
Roof plate usage=(length-shield length)×(width-shield width)
For example, the amount of PVC plastic ceiling can be calculated from the net size area. The unit price of PVC plastic sheet is 50.81 yuan per square meter, the shield length and width are 0.24M, the length of the canopy is 3M, and the width is 4.5M. The dosage is as follows:
Roofing plate usage = (3-0.24) x (4.5-0.24) approximately equal to 11.76 per square meter
Package door material usage = door outer frame length × door frame width, for example (as shown in the figure) 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
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, The door area is 2.8 square meters and the window area is 3.6 square meters. The dosage is as follows:
The amount of wallpaper used = [(2.5-0.24) × (5-0.24)] × 4-2.8-3.6 is equal to about 36.6 square meters. It is a calculation of the amount of materials used. After multiplying the amount of materials used for decoration of each part by the respective unit price, Adding up, you get the total material cost of the renovation project.
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 <br> After the type of wall color material is determined, the size of the material can be reasonably calculated based on the size of the room, taking into account the possible loss of construction, can buy more than 5% of 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
Including: S - length of required wall material (m)
L--Total length of the wall after deducting windows, doors, etc. (m)
M - the width of the wall material (m), plus 1 as a splicing pattern margin;
H--the height of the required wall material (m)
h - distance between two identical patterns on a wall material (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.
7ã€Paint>Evaluation method of coating quantity <br> Introduce a simple calculation method:
The room area (square meters) 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.
