Heating and ventilation pipeline classification design method based on BIM

Abstract

The invention discloses a BIM (Building Information Modeling)-based heating and ventilation pipeline classification design method, which comprises the following steps: connecting pipes, respectively drawing different arrangement orientations of heating and ventilation pipelines in Revit software, then systematically distinguishing and classifying the pipelines according to names and materials, and finally correspondingly setting colors according to different materials. And finally, all the pipelines are connected with the connecting pipes through bolts. By arranging an automatic dredging mechanism, when a large amount of residues adhere to the inner wall of a heating and ventilation pipeline B, the heating ventilation capacity of the heating and ventilation pipeline B is reduced, and the pressure in a connecting pipe and a heating and ventilation pipeline A is increased, so that a sliding block in the connecting pipe slides in a sliding groove under pressure to extrude an elastic plate to deform, and a push plate is pushed to slide in the connecting pipe; the outer wall of the heating and ventilation pipeline A and the outer wall of the heating and ventilation pipeline B are pushed out, the outer walls of the heating and ventilation pipeline A and the heating and ventilation pipeline B are scraped in real time, and it is guaranteed that the outer walls of the heating and ventilation pipeline A and the heating and ventilation pipeline B are clean and not corroded.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation pipelines, in particular to a BIM-based classification design method for heating and ventilation pipelines. Background technique [0002] The thickness and specifications of the HVAC pipes can be changed according to the requirements. Usually, when connecting, the two ends of the air pipes are always externally connected to the fittings (such as elbows, reducing diameters). Under normal circumstances, there are no grooves at both ends of the heating and ventilation pipes and there are sealing rings. At present, after the classification and design of the arrangement and classification of the heating and ventilation pipes are completed, on-site installation is required. During the installation, multiple heating and ventilation pipes are often connected through connectors. Long-term ventilation of gas inside leads to a large amount of residue and dust adhering to the inner wall of th...

Problems solved by technology

At present, after the classification and design of the arrangement and classification of the heating and ventilation pipes are completed, on-site installation is required. During the installation, multiple heating and ventilation pipes are often connected through connectors. Long-term ventilation of gas inside leads to a large amount of residue and dust adhering to the inner wall of the pipe. As time goes by, the inner diameter of the HVAC pipe becomes smaller and smaller. It is very troublesome for the staff to disassemble and clean, and affects the heating ventilation.
