【 Weak current College 】 housing area for correct measurement method

How to measure the housing area in recent years, on the commercial area of the dispute and more and more, in the final analysis, are some unscrupulous developers "playing area maoerni". Because, when we buy a House, typically by the real estate business provides out-of-the-floor data. So how to do "good idea" to that end, we invited the experts of the commercial area of the self-test. Tools: normal tape measure, calculator. Note: the calculation refers to the measurement and calculation of two different steps. Measurement: mainly volume from the actual size of the House. 　　　　Step one: get detailed standard layer or home floor plan. According to the detailed residential plot measurement and calculation can easily and accurately. 　　　　Plan should include the main residence are: the data room axis dimension (that is, load-bearing walls or columns of the dimension between) and the total size of the wall, that is, two dimension lines, there are various room area. Most households are in the standard tier, measurement and calculation of main under standard floor plans and area. If the residential floor more special, as is the top floor, with a floor of drawings. In order to calculate a area, you can not make the whole floor area measurement. Step 2: measurement and calculation of their own internal use area and the building area. Use the calculation of the area. Measurement of room inside the dimensions, the axis size minus the room wall thickness and the size of the thickness of the plastering, cannot be a acreage in size. That is, according to the size of the area was not a use area. Ares is the axis dimensions drop structure thickness dimensions interior dimensions of the room. In General, the load-bearing walls are brick, fabric thick 24cm, thickness of exterior wall structure in cold areas as 37cm, concrete wall thickness 20cm or 16cm, non-bearing walls 12cm, 10cm, 8cm, not, etc. In General, the axis is located in the middle of the wall, the middle is half on each side wall thickness. Lime plaster thickness is generally 2-3cm. Measurement location should be at ground level 1-1.2 m height. For axis dimensions 360cm room measurements should be 360-20-2.5 × 2 = 335cm. As far as this can be estimated more room inside the axis dimensions, calculation of dimensions 340cm 360cm. Size error if within a few centimetres, the plaster thickness is not accurate, not even, generally do not affect the axis dimensions and room internal dimensions. If the error is close to or exceed 20cm may have a problem. Measurement rooms in two interior dimensions of the direction, multiplying the area of the room. Window and door openings in the area are not included in the area. Each room (includes: entrance hall, corridor, Hall, bedroom, kitchen, bathroom, storage room, balcony, wallpaper, non-fixed structure surrounding space) use area and residential area of total use. Residential construction area calculation will own residential and other places, public part of the adjoining Office along the axis, the total area between their axis as in residential buildings with a total construction area. Its calculation method, one will always use the area plus the wall structure area; one is directly calculated their axes of the geometry of the surrounding area. But in residential buildings with a total construction area in the drawing are generally not tagging, no real significance, only for the next calculation package residential construction area of use.
