I. Plan

Definition of floor plan: it is a horizontal projection plan projected downward above the building area.

The function of the plan: construction site plan is to express the position and orientation of the building, the relationship with the original building, the surrounding roads, the green layout, and the topography.

The general construction plan can be used as the basis for building, construction lofting, earthwork construction and general construction layout.

The building plan mainly reflects the plane shape, size and room layout of the house, the position, thickness and material of the wall (or column), the position and opening direction of doors and windows, etc.

The building plan can be used as an important basis for setting out construction, installing walls, columns, doors and windows, interior decoration and budget.

Second, introduction.

Definition of sectional view: A sectional view is an internal image of this group of objects cut from the vertical and horizontal directions.

1. It is assumed that the same or more vertical sections perpendicular to the axis of the external wall will cut open the house, remove the part close to the observer, and carry out orthographic projection on the rest.

2. The building section is the vertical section of the whole building.

Function of profile: Architectural profile is mainly used to express the vertical height of the building, the situation of the building, and the brief structural form and construction method.

It is one of the indispensable and important pictures in building construction, which is in harmony with the building plane and facade.

Attachment: Definition of elevation:

Definition of elevation view: elevation view refers to the outermost image of a group of objects on the vertical horizontal plane, drawn by the principle of orthographic projection, and the projection plane is parallel to the external wall of the house.

Function of the facade: the facade mainly reflects the shape and appearance of the house, the form and position of doors and windows, the materials of the wall and the decoration practices. , is an important basis for construction.
