Ventilation ducts can now be ubiquitous, with ventilation ducts installed in our office space as well as in some public buildings. In the ventilation duct installation, we must first according to the specific structure of the building to carry out targeted design, design details or not and reasonable or not, directly affect the ventilation duct installation difficulty and quality. Next, let's COMIFO duct forming machine manufacturers introduce you the design points before the ventilation duct installation.
1, First of all, according to the ventilation system of a certain floor to draw, and indicate the location of the interface.
2, Ventilation duct design should be numbered, starting from the beginning numbered, the starting point for the general interface position, the same section specifications, the same length section for the same number, which should be numbered in sequence. In order to facilitate the organization of construction.
3, Ventilation duct line design must mark the support hanger position, support hanger position spacing and all material specifications must meet the code requirements and technical requirements.
4, The production of ventilation duct design should give priority to elbows and reduce the diameter of the inner and outer surface to meet the concentric elbow requirements, variable length requirements.
5, Ventilation duct design should mark the beginning and elbow position, diameter position, the axis of the duct position, the bottom elevation.
Only by grasping these points, in strict accordance with the above principles to design, in order to develop a reasonable plan to facilitate the post-ventilation duct processing and ventilation duct installation. This is an interlocking process and must be done right from the start.
