What is modular Prefabrication coordination?
It is understood by the interdependent arrangement of a dimension based on a primary value accepted as a module.
Modular Coordination Rules
- Assembly of a single element in large components.
- Few possible different types of components.
- Minimum waste of cut required.
A set of rules would be adequate to meet the requirements of the conventional and prefabricated structure.
These rules are adaptable for a planning grid in both directions of the horizontal plane
- first 3M for residential and institutional buildings,
- For industrial buildings,
- 15 m for sections up to 12 m
- 30M for sections between 12m and 18m
- 60M for sections of more than 18m
The centre lines of the load-bearing walls must match the lines of the grid
- In the case of external walls, the grid lines should coincide with the central line of the wall 5cm from the inner face of the wall.
- The planning module in the vertical direction will be 1M up to a height of 2.8M inclusive.
- Preferred increments for fixed heights, doors, windows and other windows should be 1M.
- In the case of internal columns, the grid lines will match the centre lines of the columns.
In the case of external columns, the grid lines will coincide with the centre lines of the columns on the floor. A basic module can be represented as a module and for larger project modules they are represented.
The floor height is set between the levels of the finished floor at 2.8 m and if the thickness of the slab is <15 cm, the floor height is set at 2.7 m. The central distance between the load walls can be chosen from a set of modules. The use of other dimensions is not allowed.
In the design of a building, the modular grid can be used consisting of a parallel line spaced in value of the M module and a grid line chosen as the basis for establishing a part of a building becomes a modular axis.
The interior walls are positioned so that their central lines coincide with the modular axis.
The centre line of the grid is found by deducting the size of the duct.
Prefabricated construction depends on the extent of the use of prefabricated elements, its characteristics should be considered when designing a method.
- Intensive use of spaces
- Scheme of straight and simple walls
- Limited sizes and numbers of components.
- Limited opening in load walls.
- Regulated partition locations
- Standardized service and stair units
Limited sizes of doors and windows with regulated positions
- Structural clarity and efficiency
- Suitability for adoption in low and high-rise blocks
- Ease of manufacture, storage and transport.
- Speed and ease of erection
- Simple joint system
