Decoration market there are many tricky, at present, individual decoration companies to dig consumers to 'gig' more and more covert, home improvement market more and more tricky,' then, how much do you know about paving workers' tricks? Xiao Bian today Everyone talks about the tricky content of bricklayers and hopes to help friends in need.
How to prevent the tricks of the bricklayers
Before you purchase a kitchen tile, you must calculate the area that you need to lay it on. The general area measurement can be obtained. The calculation method shown in the table below is available.
Pay attention to two points: First, after calculating the actual area, pay attention to the number of tiles sold rather than the area;
Second, we must add a certain amount of losses. Generally, the loss is 5-10%, and the small brick is about 3%. Otherwise, the time spent on filling the bricks will be delayed and the batch inconsistency will have a chromatic aberration effect.
Calculate the number of tiles by area
The total number of tiles = tiles tile area (square meters) ÷ (the length of a single tile × the width of a single tile)
Such as: 20 square meters of 120 × 120mm specifications of a total of how many tiles to buy?
The total number of sheets = 20 m 2 ÷ (0.12 m × 0.12 m) = 1388.9 (pieces)
Note: When calculating the number of pieces, it should be noted that the units are uniform, so the length and width of the tiles should be converted from millimeters (mm) to meters (m).
If the result of the calculation is a decimal, the decimal point is generally calculated using the “round up†method, ie, 1389 pieces, and another loss is required to purchase the tile.
alert! Profiteering algorithm is tricky! Sneak away your money secretly! 11.8.3 Real Events
"Yesterday I bought a white bread brick with a specification of 120mm*120mm in the store. When I opened the bill, I calculated the price in square meters. I had 120 square meters. I didn't ask how many square meters I had at the time. Today, the tiles were delivered, we bought 20 square meters, and they counted us 65 sheets per square meter, a total of 1300. At that time, there was a question... The delivery master said that because of the small bricks that were to be left..." The result is that there should be at least 1,380 tiles. As a result, the merchants only sent 1,300 pieces, which was a total of more than 80 pieces. After complaints tossed, a total of 1,340 tiles were eventually delivered by the merchants.
Compared with the following calculation methods, the rough look is basically the same, and the intentions will be found in the heart:
Algorithm 1: The number of bricks per square contains × squares = [1 ÷ (0.12m * 0.12m) × (coefficient)] × 20 = ≈ 67 × 20 = 1340 [this algorithm is easy to play tricky]
Algorithm II: tile laying area (square meters) ÷ (length of single tile × width of single tile) = 1389 pieces [reasonable algorithm]
Mystery: The square number is correct, the number of pieces is less! Pay per square, but the number of bricks per square is rounded (some merchants will also get a conversion factor, or as the above-mentioned merchants make a joint, claiming that the internal regulations play tricks), the total number of tiles is unknowingly reduced Now. Although 1 level is not felt, the number of squares purchased is a lot, and it is a big loss for consumers.
Conclusion: When estimating the price, you can estimate it in square meters, but to buy a tile, be sure to confirm the number of pieces with the merchant. This will prevent the merchant from playing tricks on the algorithm and unwittingly take away your money.
Calculate the number of waistlines by length
First, ask the tiling worker to measure the total length of the waist line to be attached. The calculation method is:
The total number of pieces = the total length of the waistline, the length of the single waistline
For example, the length of the waistline is 10 meters, and the size of the selected waistline is 80mm*3mm brick.
The total number of tablets = 10m ÷ 33m = 30.3 tablets
The decimal point is generally calculated using the upward rounding method, so the result is 31, buy 1-2 more.
Xiao Bian concludes : The tricky content of the bricklayers is introduced to this and I hope to help you. More exciting information is on this site.
