Building modulus refers to the selected size unit, as a value-added unit in scale coordination, and it is also the basis for scale coordination of departments such as architectural design, construction, building materials and products, building equipment and building assembly. Its purpose is to make the installation of components consistent and interchangeable. In China's architectural design and construction, it is necessary to follow the coordination standard of building modules (GB50002-20 13).
Extended data:
First, related use.
The standard size units selected by buildings and their components (or assemblies) are called building module units as value-added units in size coordination. The basic dimension unit selected in building module coordination is 100mm and the symbol is m, that is, 1M= 100mm, which is the basic module in most countries in the world at present.
The integer value of the basic modulus is called the extended modulus. Integer divided by basic modulus is called fractional modulus. Modulus is a unit of measurement, and the value of this unit of measurement is expanded into a series to form a module series. The modulus series can be obtained by multiplying the basic modulus m.
Modular series plays an important role in the industrial production of buildings, because with its help, some parts or semi-finished products can be separated without any spare parts and sent to the machine accurately. Modulus can be used as a measure of architectural design basis, which determines the exact size of building components and the position of building components in the system and the building itself.
Modularity in architectural design is represented by modular grid. The size unit of the grid is the basic modulus or expansion modulus. In architectural design, every building component must establish a certain relationship with grid lines. The center line, eccentric line or sideline of building components are generally located on the grid line.
The main building components in architectural design, such as load-bearing walls, columns, beams, doors and windows, should meet the requirements of modularity and strictly abide by the rules of modularity, so as to facilitate the industrial production and assembly construction of building components.
Second, scale.
1. dimensioning: used to mark the distance between building positioning axes (such as bay or column spacing, depth or span, height, etc.). ) and the dimensions between the location boundaries of building components, building components, building products and related equipment. The marking size shall conform to the provisions of the modulus series.
2. Structural dimensions: the design dimensions of building components, building components and building products. Generally speaking, the symbol size minus the gap is the structural size. Gap size should comply with the provisions of the modulus series.
3. Actual dimensions: the actual dimensions of building components, building components and building products after production. Due to production errors, this size is different from the design structure size, and this difference should comply with the provisions of the construction acceptance specification.
