Architectural engineering construction area calculation specification provisions description

1 General provisions

The building in China 1.0.1 area calculation rules in the 1970s by the former Soviet Union approach combined with our situation developed by the National Capital Commission in .1982 Office (82) via radicals set Word 58, issued the construction area calculation rules are on the 1970s the construction area calculation rules for amendments. In 1995, the Ministry issued the national unification architectural engineering budget engineering calculation rules (civil engineering GJI) cz-101-95), which included the "building area calculation rules" (hereinafter referred to as "the original area calculation rules"). For the 1982 construction area calculation rules for amendments.

Historically, the building area calculation rules in the construction cost management plays a very important role in the building housing the calculation of quantities of key indicators, is calculated unit project budget cost per square meter of main basis. Is the summary statistical departments publish housing construction area of completion of the Foundation. Currently, the Ministry of construction and national quality technology supervision Bureau issued the real measurement standards "of the real estate area, as well as the residential design specifications" in the area of computing, are based on the building area calculation rules. As China's construction market development, the building of new structures, new materials, new technologies, new construction methods, in order to address the building technology development in the area of computational problems that make a building area of more scientific and rational, improvement and harmonization of building area of computing and computing methods, on the construction market play a bigger role. Therefore, on the building area of calculation rules to be amended. Considering that the construction area calculation rules for the important role that this will be the construction area of calculation rules to the architectural engineering construction area calculation specifications (hereinafter "the code").

The scope of this specification 1.0.2 is a new, expanded and reconstructed for industry and civil construction engineering construction area of computing, including industrial plants, warehouses, public buildings, residential buildings, agricultural production used for housing, grain kind of warehouse, subway station, and a building area of computing.

3 calculate the area of

3.0.1 the specification construction area of computing is to Le feet above outside the exterior wall structures route calculation. Le foot is the wall is part of the root is short wall thickening, cannot represent the entire exterior wall structure, therefore to deduct Le foot thick walls.

3.0.2 storey height should be different to determine its size calculation. Its height means indoors ground elevation to the roof deck structure in the vertical distance between the elevation. Where to find the slope of the roof-flat roof-deck building. Its height means indoors ground elevation to roof panel lowest plate surface structure of the vertical distance between the elevation.

On the sloping roof space how to calculate area, we reference the residential design code of the relevant provisions of the sloping roof height measured according to the different buildings to determine its size calculation. Clear height means the floor or ground comes first at the end of the floor or ceiling vertical distance between the bottom surface.

3.0.3 multi-storey buildings of architectural area calculation should be based on different floors respectively. Storey height refers to the upper and lower floor structure of the vertical distance between the elevation. Building the bottom storey, Foundation Press Foundation slab surface structure on the first floor of the structure of the vertical distance between the elevation; no base means the ground elevation is Supreme floor structure for the vertical distance between the elevation, the highest level of storey is its elevation of floor structure to the roof deck structure in the vertical distance between the elevation where to find the slope of the roof-roof, storey means buildingSurface structure of the roof panel minimum level to the Board structure at the level of the vertical distance between.

3.0.4 multi-story building sloping roof and venues stands under the space should be regarded as a space within the sloping roofs, design utilized, should be assumed to determine their size calculation. Design does not use space, building area should not be evaluated.

3.0.5 basements, half basement walls to its estuary edge the Wai level area calculation. The calculation rule by the basement, semi basement walls perimeter level on the estuary area calculation, not very closely on the text, "the wall" on the estuary is easy to understand for basements, half basement of a building's exterior wall. Due to the exterior and basement walls of the center line is not necessarily fully overlapping, mostly I extrude or recessed basement wall centre line.

3.0.6 built in a building on suspending aerial layer (see Figure 1).

Figure 1 slope construction crane feet overhead layer

The provisions of this section on the original 3.0.9 were revised and increased parking area calculation. Garage, warehouse, three-dimensional stacks does not stipulate whether retaining structure, according to whether there is a structural layers. you should distinguish between the different layers high determine the scope of building area calculation. change according to the shelves and shelves of tier computing area.

This section called the "3.0.12 venue" essentially means "field" (for instance: the football field, tennis courts, etc.) have permanent cover on the stand. The "Museum" is a permanent top and envelopes shall, at the single-layer or multi-layer architecture related requirements calculation area.

In case of building roofs 3.0.13 staircase is the slope of the roof, pitched roof should be according to the relevant provisions in the computing area.

3.0.14 with envelope is not perpendicular to the horizontal plane and beyond the bottom outer edge of the building is a building tilt wall. in case of an inclined to building walls, sloping roof should be considered. According to the relevant provisions of the sloping roof area calculation.

3.0.15 indoor stairway area calculation, you should press the staircase attached buildings the calculation of natural floors and the building area. In case of thermocline architecture, its common indoor stairs should be natural tier computing area: upper and lower error levels Middle air-condition common Interior stairs, candidates with a layer of

Figure 2 Schematic staggered section Middle air-condition

3.0.16 awning with its width exceeding 2.10m or not exceeding balance, more than 2.10m 2.10m users should press the awning fabric plate horizontal projection area calculation of l, 2. The column with column awning and awning calculation should be consistent.

3.0.17 outdoor staircase, at the top of stairs without permanent cover, or cannot fully cover the stairs of the awning. The upper stairs not calculate area, upper staircase can be considered as the lower stairs of permanent cover, lower stairs area should be evaluated.

3.0.18 building terrace, balcony concave balcony, balconies, closed and closed terrace are its horizontal half of the projection area.

3.0.19 shed, booths, platform, station, toll, etc., area calculation. Due to the development of architectural technology, many new structures, such as column no longer simply an upright column, but there are V-shaped pillars,

Inverted ^ column, different types of columns, giving the area a lot of controversy, and we don't to column to determine the area of computing, and the top cover of the horizontal projection area calculation. In the carport, booths, platform, station, toll stations are equipped with a support structure for managing rooms, lounges and other press-related provisions of the PCT area calculation.

3.0.23 this specification refers to building expansion joint is connected with the building of deformation seams, which is exposed in the building, in a building can be seen by the deformation of joints.

3.0.24 other building area should not be evaluated.

6 prominent wall of Le feet, with walls buttress, steps, wall plaster, decorative surfaces, glued on the block layer, decorative curtain wall, conditioners shelf (box), floating window, Widget, gadget, width in 2.10m and within the canopy and buildings not connected to the pass of decorative balcony, pick Gallery are not part of the building structure, building area should not be evaluated.

8 escalator (helical walkway by escalator), apart from both ends of the floor boards or beams, the ladder itself belongs to the device. The calculation for this ladder is not suitable for the construction area. Level trail (escalator) is installed in the floor on the device, it should not be a separate calculation area.
