Tips on measuring a house

The analysis is as follows:

1. House measurement skills

1. The correct order of house measurement:

Measuring a house generally begins with the entry into the house. Start at the door, measure in a circle, and finally return to the other side of the entrance door to measure all the rooms in the house. If it is multi-layered, in order to avoid missing measurements, the order of measurement should be to measure one layer before measuring the other, and the order of the rooms should be from left to right.

2. Length and height measurement method:

When using a tape measure to measure the length and height of a specific room, the length should be measured close to the ground and the height should be measured close to the corner of the wall. Measurement. Unless there are special circumstances, the floor height is basically certain. Just find two places to measure the average floor height.

3. Positioning methods for doors, windows, etc.:

All dimensions are divided into segments, just like geometry. After measurement, the data is recorded at any time. First, measure the door itself. Length, width, height, then measure the left and right distance between the door and the wall to which it belongs, and measure the distance between the door and the ceiling.

2. Three measurement ideas for measuring rooms

1. Quantitative measurement:

Mainly measure the length, width, and height of each hall, and calculate the length, width, and height of each room. The area of ????a room with different uses. And make reasonable suggestions based on the owner's preferences and daily habits.

2. Positioning measurement:

In the measurement of this link, the positions of doors, windows, and air-conditioning holes are mainly marked, and the scalar quantity of windows is required. In the measurement of the kitchen and bathroom, the location of the downpipe, hole spacing, toilet pit hole spacing, distance from the wall, location of the smoke pipe, gas pipe location, distance under the pipe, and floor drain location all need to be accurately measured so that in the future accurate positioning in the design.

3. Height measurement:

Under normal circumstances, the height of the house should be fixed. However, due to the different architecture and structure of each house, there may be a certain gap. When the designer performs height measurement, he must carefully check whether there is a gap in the height of each area of ??the room, so that it can be accurate in future design drawings. Correct.

Measurement classification

1. Direct measurement: the measured object is obtained directly without the need for auxiliary calculation of a certain functional relationship between the measured object and other actual measurements. Worth measuring.

2. Indirect measurement: The measurement of the measured parameter value is obtained by directly measuring other quantities that have a known functional relationship with the measured parameter.

3. Contact measurement: The measuring head of the instrument is in direct contact with the measured surface of the workpiece, and there is mechanical force measurement (such as contact three-coordinate, etc.).

4. Non-contact measurement: There is no mechanical measuring force between the measuring head of the instrument and the measured surface of the workpiece (such as optical projectors, pneumatic measuring instruments and image measuring instruments, etc.).

5. Combined measurement: If there are multiple measured quantities, although there is a certain functional relationship between the measured quantity (unknown quantity) and some intermediate quantity, because the functional formula has multiple unknown quantities, the intermediate quantity It is impossible to find the measured value in one measurement. At this time, you can obtain some measurable different combinations by changing the measurement conditions, then measure the values ??of these combinations, and solve the simultaneous equations to find the unknown measurand.

6. Comparative measurement: The comparison method refers to a method in which the measured object is compared with a known similar measurer on a comparator to obtain the measured object. This method is used for high-accuracy measurements.

7. Zero method: The measured quantity is compared with the known quantity so that the difference between the two is zero. This method is called the zero method. For example, bridges, balances, steelyards, galvanometers

8. Offset method?: The measured object directly acts on the measuring mechanism to deflect or displace the pointer to indicate the size of the measured object.

9. Substitution method?: Substitution method is to connect the measured quantity and the known quantity to the same measuring instrument one after another, so that the indication values ??of the two measuring instruments are the same without changing the working condition of the instrument, then The measurand is considered equal to the known quantity. For example, Cao Chong weighs the elephant.

10. Accumulation method: The value of the object being measured is too small to directly measure a single object with a measuring instrument. Then a method of measuring a collection of objects of the same specification and then finding the average, such as measuring The thickness of a piece of paper, the diameter of a hair, the mass of a staple, etc.
