by 1、 What components are included in the first floor (I) what components are included in the first floor enclosure? The components included in the first floor enclosure may include: columns, beams, internal and external walls, doors, windows, door couplers, wall openings, lintels, window sills, window guard railings and other components.
See figure 1: Figure 1: components included in the enclosure （2） Which components are included in the top structure of the first floor? The components included in the top structure of the first floor may include: slab, slab hole, lower empty beam, etc.
see Figure 2: Figure 2: components included in the top structure （3） Which components are included in the indoor structure of the first floor? The components included in the indoor structure of the first floor may include: stairs, indoor independent columns, pools, test benches and other components occupying the indoor space.
See Figure 3: Figure 3: components included in the indoor structure.
Among them, stairs, pools and test benches belong to composite components, which need to be subdivided until they can be calculated.
1.
Stair components are subdivided into stair packages See Figure 4 for the component categories included: Figure 4: schematic diagram of stair component categories 2 See Fig.
5: Fig.
5: schematic diagram of pool Component Category 3 The component categories of the test bench are subdivided.
See Figure 6: Figure 6: schematic diagram of component categories of the test bench （4） Which components are included in the outdoor structure of the first floor? The components included in the outdoor structure of the first floor may include: building waist line, bay window, door and window sleeve, apron, ramp, step, balcony, awning, cornice, sunshade, air conditioning board and other components other than the outer wall skin.
See Figure 7: Figure 7: components included in the outdoor structure, in which bay window, ramp, step, balcony, awning and cornice belong to compound structure Composite components need to be subdivided until the quantity can be calculated.
1.
The component categories of the bay window are shown in Figure 8: Figure 8: schematic diagram of the component categories of the bay window 2 The component categories included in the ramp component subdivision are shown in Figure 9: Figure 9: schematic diagram of ramp Component Category 3 See Fig.
10: Fig.
10: schematic diagram of step component category 4 The component categories of balcony are subdivided.
See Figure 11: Figure 11: schematic diagram of balcony component category 5 The component categories included in the awning are shown in Figure 12: Figure 12: schematic diagram of awning component categories 6 The component categories included in the cornice are shown in Figure 13: Figure 13: schematic diagram II of the component categories of the cornice.
What components are included in the other layers? The above comprehensive analysis of which components are included in the first layer.
In fact, the components included in each layer are different to varying degrees.
Let’s analyze which components are included in the other layers.
（1） Component category of foundation layer the foundation layer is still decomposed according to the principle of six blocks, but the top structure is replaced by the bottom structure.
According to different foundation types, it is divided into raft foundation, strip foundation, independent foundation and pile cap foundation.
1.
Raft foundation layer.
The components contained in raft foundation layer are shown in Figure 14: Figure 14: schematic diagram of six blocks of raft foundation.
2.
Strip foundation layer The components contained in the foundation layer are shown in Figure 15: Figure 15: six block schematic diagram of strip foundation 3.
Independent foundation layer.
The components contained in the independent foundation layer are shown in Figure 16: Figure 16: six block schematic diagram of independent foundation 4.
The components contained in the pile cap foundation layer are shown in Figure 17: Figure 17: six block schematic diagram of pile cap foundation （2） Which components are included in floor – N ~ – 2? Floor – N ~ – 2 is all buried underground and belongs to the whole basement.
The components included in enclosure structure, roof structure, indoor structure and indoor decoration are the same as the first floor.
The outdoor structure has become backfill.
We have made statistics on the foundation floor, and the outdoor decoration has become external wall waterproof.
See Figure 18: Figure 18: six block schematic diagram of floor – N ~ – 2 （3） Which components are included in floor-1? Floor-1 is a semi basement, partially buried underground and partially buried on the ground.
The components included in the enclosure structure, top structure, indoor structure and indoor decoration are the same as the first floor.
The backfill in the outdoor structure has been counted in the foundation layer.
The apron, steps and ramps in the outdoor structure should belong to floor-1 from the perspective of elevation, but the figure is not clear These components are generally drawn on the first floor, so apron, steps and ramps are usually included in the first floor calculation- The outdoor decoration of the 1st floor has become two parts here, of which the buried part has become the outdoor decoration, and the exposed part belongs to the exterior wall decoration, which is generally also included in the calculation of the first floor.
See Figure 19: figure 19: schematic diagram of six blocks on floor – 1 （4） Which components are included in floors 2 ~ n? Floors 2 ~ N generally belong to the standard floor of the building.
The components included in the envelope structure, roof structure, indoor structure, indoor decoration and outdoor decoration are the same as the first floor.
The balcony, bay window and air conditioning board are the most frequent in the outdoor structure.
Apron and terrace generally do not appear.
See Figure 20: Figure 20: six block schematic diagram of floors 2 ~ n （5） Which components are included in the top floor? The top floor may appear many times in the building, but the principles followed are the same.
The envelope structure, top structure, indoor structure and indoor decoration are the same as the first floor.
The eaves and awning usually appear in the outdoor structure, and the external wall skirt usually does not appear in the outdoor decoration.
See Fig.
21: Fig.
21: six block schematic diagram of the top floor （6） Which components are included in the roof layer? The roof layer, like the top layer, may appear many times in the building.
We can regard the roof layer as a large room without a roof.
Among them: ◆ enclosure structure: parapet, structural column, coping and protective railing usually appear.
◆ top structure: does not exist in the roof layer.
◆ indoor structure: usually components such as flue and ventilation duct.
◆ outdoor structure: if the cantilevered canopy is included in the top layer, there will be no components in the outdoor structure of the roof layer.
◆ interior decoration: at this time, the ground becomes the plane part of roof waterproof on the roof layer, the skirting becomes the curling part of roof, the wall becomes the interior decoration of parapet, and the dado and ceiling will not appear.
◆ outdoor decoration: it is the external decoration of parapet.
See Figure 22 for the schematic diagram of the six blocks of the roof layer: Figure 22: schematic diagram of the six blocks of the roof layer.
