How to calculate the wrapping force by projection area
The width of the shape of an object standing on the wall multiplied by the height is the projection area of the object, that is, the length * height of the projection plane. Through such calculation, the projection area can be calculated
the building area of the balcony inside the apartment is calculated according to the horizontal projected area between the balcony periphery and the external wall of the house. The construction area of closed balcony is calculated according to the horizontal projection, and the construction area of unclosed balcony is calculated according to half of the horizontal projection
extended data:
precautions for projection area calculation:
projection area is the length of the wardrobe multiplied by the height of the wardrobe. When the unit price is known, the projection area multiplied by the unit price can get the total cost of the wardrobe
when measuring the length of the wardrobe, the position of the door and switch should be reserved 150-200 mm, which should be cut off
the height of the wardrobe is from the ground to the top. Generally, the height of the wardrobe is more than 2200mm to 2400mm, and the top cabinet will be made on it
the user can also calculate the area of each side of the cabinet separately, add the areas of these sides, and the overall area of the seat is the projection area
How to calculate the projected area:
the built-in area of a complete set of houses is composed of three parts: the usable area of the built-in house, the built-in wall area and the built-in balcony area
1. The use area of the house: the use area of the house is the use area of the house, and the horizontal projection area is calculated according to the following provisions:
a. the use area of the house is the sum of the space areas of the bedroom, living room, hallway, aisle, kitchen, toilet, toilet, storage room, closet, etc
B. the total area of internal stairs in the set is included in the use area according to the total area of natural floors
The chimneys, ventilation cts and pipe wells inside the casing not included in the structural area are included in the service area The decorative thickness of the inner wall is included in the use area2. The area of the interior wall: the area of the interior wall is the area occupied by the maintenance or load-bearing wall or other load-bearing support around the use space of the interior, in which the partition wall between each set, the partition wall between the set and the public building space, and the common wall (including the gable) are included in the interior wall area according to half of the horizontal projection area. The free wall in the sleeve is included in the wall area of the sleeve according to the horizontal projection area
3. The building area of the balcony in the apartment: the building area of the balcony in the apartment is calculated according to the horizontal projection area between the balcony periphery and the external wall of the house. The construction area of closed balcony is calculated according to the horizontal projection, and the construction area of unclosed balcony is calculated according to half of the horizontal projection
what is the projected area:
assuming that the sun is at the top, the area surrounded by the outer contour of the shadow of the house on the ground is called its horizontal projected area. In fact, in general, it is the area on the construction plan of the component
is generally used in building construction, for building area calculation
< H2 > reference: Internet_ Projection area1、 What is the projected area
Assuming that the sun is at its zenith, the area surrounded by the outer contour of the house's shadow on the ground is called its horizontal projection area. In fact, in general, it is the area on the construction plan of the componentis generally used in housing construction and building area calculation
How to calculate the projection areathe built-up area of a complete set of houses consists of three parts: the use area of the house, the wall area and the balcony area
1. Usable area of the apartment: the usable area of the apartment is the area of the usable space of the apartment, and the horizontal projection area is calculated according to the following provisions:
a. the usable area of the apartment is the sum of the spaces of the bedroom, living room, hallway, aisle, kitchen, toilet, toilet, storage room, closet, etc
B. the total area of internal stairs in the suite is included in the use area according to the total area of natural floors
C. the chimneys, ventilation cts and pipe wells inside the casing not included in the structural area are included in the service area. d. The thickness of interior wall decoration is included in the use area
2. Inner wall area: the inner wall area is the area occupied by the maintenance or load-bearing walls or other load-bearing supports around the inner use space, in which the partition wall between each set, the partition wall between the set and the public building space, and the common wall (including gable) are included in the inner wall area according to half of the horizontal projection area. The free wall in the sleeve is included in the wall area of the sleeve according to the horizontal projection area
Take the wardrobe as an example:
the projection area is the length times height of the whole wardrobe. Suppose that the length of a wardrobe is 3 meters, the height is 2.5 meters, and the unit price is 600 yuan / m2, then the total cost of the wardrobe is 3 × two point five × 600 = 4500 yuan
the built-in area of a complete set of houses consists of three parts: the usable area of the built-in houses, the built-in wall area and the built-in balcony area
1. The use area of the apartment
the use area of the apartment is the area of the use space of the apartment, and the horizontal projection area is calculated according to the following provisions:
a. the use area of the apartment is the sum of the space areas of the bedroom, living room, hallway, aisle, kitchen, toilet, toilet, storage room, closet, etc
B. the total area of internal stairs in the suite is included in the use area according to the total area of natural floors
C. the chimneys, ventilation cts and pipe wells inside the casing not included in the structural area are included in the service area
D. the decorative thickness of the inner wall is included in the use area
2. The area of the interior wall
the area of the interior wall is the area occupied by the maintenance or load-bearing walls or other load-bearing supports around the use space of the interior, in which the partition wall between each set, the partition wall between the set and the public building space, and the common wall (including the gable) are included in the interior wall area according to half of the horizontal projection area. The free wall in the sleeve is included in the wall area of the sleeve according to the horizontal projection area
3. The building area of balcony in the apartment
the building area of balcony in the apartment is calculated according to the horizontal projected area between the balcony periphery and the external wall of the house. The construction area of closed balcony is calculated according to the horizontal projection, and the construction area of unclosed balcony is calculated according to half of the horizontal projection
Annex: the common building area of a house
the common building area of a house refers to the building area jointly occupied or jointly occupied or used by all property owners. The common building area includes: elevator shaft, pipe shaft, staircase, garbage channel, substation room, equipment room, public hall, aisle, basement, ty guard room, etc., as well as the building area of public and management rooms serving the whole building, calculated by horizontal projection area
the common building area also includes the partition wall between the condominium and the public building space, and half of the horizontal projection area of the external wall (including the gable)
independent basement, garage, guard room for multiple buildings, management room and basement as civil air defense project are not included in the common building area. On this issue, I would like to explain to you the following concepts: building area, public shared area and real building area
usually, the price in advertisements and sales Books refers to the price of "building area" per square meter, and "building area" includes the public shared area and the actual building area. The building area includes the usable area of housing, the floor area of wall and column, the area of stairs and corridors, and other shared areas
in terms of calculation method, the building area refers to the horizontal projection area of the periphery of each floor above the external wall (column) plinth of the house, including balcony, corridor, basement, outdoor stairs, etc., and it is a permanent building with upper cover, solid structure and floor height of more than 2.2m (2.2m)
"actual construction area" is commonly known as "practical area". It is the balance of "building area" after decting public apportioned area. Therefore, we think that the private area you mentioned should be understood as "actual construction area"
the area directly available to the owner is called "usable area", commonly known as "floor tile area". It is a concept of content space after decting the space occupied by columns, walls and other buildings on the basis of practical area. That is, the total usable space area of the house is calculated according to the horizontal projection of the interior wall of the house
it is worth noting that there is a lot of room for sharing. The shared area refers to the building area jointly occupied or used by all property owners. The current shared area mainly includes stairs, elevators, aisles, the first floor lobby, etc., and the shared area of some buildings also includes the allocation of water room, electricity room, security booth and other supporting facilities. For the treatment of public apportioned area, there is no accurate legal norms, this problem, buyers should not underestimate
ten cases are not included in the building area
according to the new national standard "code for real estate measurement", the building area is not included in the 10 cases
1. Mezzanine, intercalation, technical floor, basement and semi basement with floor height less than 2.20M
2. The components, accessories, decorative columns, decorative glass curtain walls, buttresses, plinths, steps and pillarless awning of the house wall are highlighted
3
4. The roof, terrace, garden and swimming pool of the house
5. Operation platform, feeding platform and space platform of the building, as well as the platform for placing boxes and tanks in the building
6. The ground floor of the arcade and the crossing building is used as the part of the road
7. Houses with approach bridge, viact, viact and pavement as top cover
8
9. Expansion joints between houses which are not connected with the interior of the house
10. It is understood that according to the accuracy level, the new real estate survey standard will allow the error range of 0 ± 0.26%、 ± 0.6%、 ± 4%, while the area measurement error allowed by the old standard is 1. 4%
finally, I would like to remind you that when any commercial house is delivered for use, it must be approved by a qualified professional measuring unit for the area of each house, and the measured area can be obtained. Therefore, when self acceptance, as long as the measured area is checked with the area agreed in the contract, we can know whether the area has error. If the error is large, it should be put forward to the developer in time and the solution should be negotiated.
It's the dimension from the outermost side of the external wall to the outermost side of the other (opposite) external wall. The convex and concave parts should be added or subtracted, but don't make a mistake! Then long × wide × The number of floors of the building
note:
-
contains underground area
-
the unclosed balcony is counted as half of the area
-
technical layer less than 2.2M, pipeline layer

is not included in the building area< br />
The projected area is the length of the wardrobe multiplied by the height of the wardrobe
length measurement: when measuring the length of the wardrobe, it should be noted that the position of the door switch 150-200 mm should be reserved, and this part should be subtracted, and the remaining size is the length of the wardrobe (some walls may have errors e to multiple measurement data from top to bottom)
height measurement: the height of the wardrobe is the size from the ground to the top, generally when the wardrobe exceeds 2200-2400 mm, Top cabinet depth measurement: the depth of the wardrobe is generally 550mm-600mm, which is inconvenient to take things when the depth is too deep, and the depth is too shallow, which is less than the shoulder width of the human body, so it is inconvenient to hang
Interior Structure of the wardrobe
Interior Structure of the wardrobe is completely customized according to personal habits. How to divide the interior depends on how frequently you use your clothes and how easy it is to pick and place them
trousers: metal embedded handle, the diameter of trousers rack pipe is 15mm, and the surface technology is convex strip structure, which plays a role of anti-skid
hanging area: it is divided into long clothes and short clothes. Clothes such as suits and short coats are hung in the short clothing area, while women's dresses and men's coats are hung in the long clothing area
luggage area: it is better to have a special luggage area at the bottom of the wardrobe to prevent portable luggage. Fashion women can use this as a shoe storage area
laminated frame area: the face of acrylic material is polished on both sides, which is safe, fashionable, simple and beautiful, and the double section guide rail is thick and stable
bedding storage area: the most obvious advantage of custom-made wardrobe is that it can reach the top and make effective use of space. The top of the wardrobe space, generally as a large bedding storage area
changing mirror: it can be pushed and pulled, with aluminum alloy frame, four corners and corner protectors, which is more exquisite and fashionable
tie drawer: the drawer of the wardrobe adopts the more popular invisible guide rail which can automatically suck back, which is smooth and noiseless, and has better load-bearing performance
Projected area = original area × Cosine of angle between two sides
the plastering area of external wall is calculated according to the projection, and the openings of doors and windows are dected. The arc-shaped exterior wall is also projected, but the projection is the tangent normal method, that is, the arc length is multiplied by the height
in terms of calculation method, the building area refers to the horizontal projection area of the periphery of each floor above the external wall (column) plinth of the house, including balcony, corridor, basement, outdoor stairs, etc., and it is a permanent building with upper cover, solid structure and floor height of more than 2.2m (2.2m)
"actual construction area" is commonly known as "practical area". It is the balance of "building area" after decting public apportioned area
