Do you know these architectural terms?

1.What is the difference between a building and a structure?
Answer: Any space or facility where people engage in production, living, or other activities is called a building, such as apartments, factories, or schools. Structures, on the other hand, are constructions where people do not engage in production or living activities, such as chimneys, water towers, and bridges.

2.What are the "three major materials" in construction?
Answer: The "three major materials" in construction refer to steel, cement, and wood.

3.What are the three components of construction and installation costs?
Answer: Construction and installation costs consist of labor costs, material costs, and machinery costs.

4.What are nominal dimensions, design dimensions, and actual dimensions?
(1) Nominal dimensions refer to the distances between the positioning axes of a building (such as spans and depths), as well as the boundary dimensions between building products, components, and related equipment locations. Nominal dimensions must comply with modular standards.
(2) Design dimensions refer to the planned dimensions of building products and components. Design dimensions can be either smaller or larger than nominal dimensions. Typically, the design dimension plus an allowance for gaps or minus necessary support sizes equals the nominal dimension.
(3) Actual dimensions are the true measurements of building products or components. The difference between actual and design dimensions should fall within the permissible building tolerance.

5.What is a positioning axis?
Answer: A positioning axis is a line used to determine the location of the main structure or components of a building and its nominal dimensions.
