How to look at the section direction of the section in the building?

Look at the side of the section according to the number, which is the side that the eyes see. In addition, cross-sectional views are directional, and arrows indicate which direction to look at after cutting from one surface.

The number of profiles is determined according to the specific situation of the house and the actual needs of construction. The cutting plane is usually transverse, that is, parallel to the side, and can also be longitudinal, that is, parallel to the front, if necessary. Its location should be selected in a complex and typical part that can reflect the internal structure of the house, and should pass through the door and window openings.

If it is a multi-storey house, you should choose a stairwell or a different part of the floor from the floor. The name of the section shall be consistent with the number of cutting symbols marked on the plan, such as 1- 1 section and 2-2 section.

1, indicating walls, columns and their positioning axes.

2 refers to indoor floors, pits, ditches, floors, ceilings and roofs (including cornices, parapets, insulation layers or layers, skylights, chimneys, pools, etc.). ), doors, windows, stairs, balconies, awnings, holes, dados, skirting boards, moistureproof layers, outdoor floors, aprons, drains and other decorations.

3, said the floor, the underlying structure. The leader line points to the described part, and the text is described layer by layer according to the hierarchical order of its structure (as shown in Figure 3.2. 15 for the structural description of the floor and roof). If there is another detail drawing, or there is a "Structure Description Table", the description can be led out by the index symbol in the section drawing (in case of the latter, it is customary not to mark it at this time).
