Various decoration materials calculation method

1, how to calculate the amount of wall material

After the color variety of the wall material is determined, the size of the material can be reasonably calculated based on the size of the living room. Considering the possible loss during construction, it can be purchased about 10% 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

Including: S--- length of required wall material (m)

L---The total length of the four walls after deducting windows, doors, etc. (m)

M --- the width of the wall material (m), plus 1 as the margin of the stitching pattern;

H--- Height of required wall material (m)

h---The distance between two identical patterns on the wall material (m)

C---The area of ​​the wall required for up and down the window, door, etc. (m2)

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.

2, coating amount estimation method

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.

Give you a formula, wall paint construction area = (building area × 80% -10) × 3

The building area is the area of ​​purchase, and the actual utilization rate is generally around 80%. Kitchens and bathrooms are generally made of tiles and aluminum buckles. Most of the area is 10 square meters. The area derived from this calculation method includes ceilings and ceilings. The impact on the construction area of ​​the wall paint is not very great and can not be considered.

Paint quantity: According to the requirements of the standard construction program, the thickness of the primer is 30 μm. The construction area of ​​the 5 litre primer is generally 65-70 flat. The recommended thickness of the top paint is 60-70 μm. The construction area of ​​the 5 litre finish is Generally 30-35 level.

Primer dosage = construction area ÷70; finish paint usage = construction area ÷35

3. The consumption of labor, materials and machinery in the decoration budget is the main indicator in the budget quota. The calculation formula is as follows:

Fixed labor costs = fixed labor days * daily wage standards

Fixed material fee = material quantity * material budget price + loss cost + transportation fee + equipment fee + management fee + taxation. Due to the different material prices in different parts of the country, the decoration costs are not the same, but the amount of decoration project calculation formula is correct, and the amount of materials can be calculated according to the calculation formula in the following example.

Floor tile usage:

Per 100 meters usage = 100/[(block length + mortar width) * (block width + mortar width)] * (1 + loss rate)

For example, the specifications of the retro tiles are 0.5*0.5M, the seam width 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 401 blocks

Ceiling usage:

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:

Ceiling board usage = (3-0.24)*(4.5-0.24) is approximately equal to 11.76 per square meter

Package door dosage:

Package door material dosage = door frame length * door frame width

For example, as shown in the figure, a composite wood package is used for the door. The length of the outer frame of the door is 2.7M and the width is 1.5M. The amount of material used is as follows:

Package door material dosage = 2.7*1.5=4.05 square meters

Wallpaper usage:

Wallpaper Usage = (High - Shielded Length) * (Width - Shielded Width) * Number of Walls - Door Area - Window Area

Dosing and Metering Pumps

Dosing and Metering Pumps Characteristic :

1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.

2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
