Description

TECHNICAL FIELD

[0002] With the continuous development of science and technology in China, the demand for large clean electronic plant construction is increasing, and the mechanical and electrical pipeline in the clean area is becoming more and more complex. During the construction process, different professional packages are inserted and constructed, and the space management is extremely difficult. The traditional beam side rooting hanger maintenance walkway construction node is similar to the existing patent CN215759923U, which directly constructs a maintenance walkway and a suspended ceiling plate separately, forms a single-layer suspended ceiling and a maintenance walkway integrated suspended ceiling layer, and performs maintenance and installation on the subsequent fan and filter. This traditional suspended ceiling structure often causes waste of labor, construction period and economic cost due to the determination of professional package resources of the construction unit lagging behind, design drawing changes, professional package cross operation, finished product protection and other reasons, resulting in secondary modification of the clean suspended ceiling, causing waste of labor, construction period and economic cost. On the other hand, in the process of space management of mechanical and electrical pipeline, the position of the suspended ceiling hanger needs to be considered comprehensively, and the hanger spacing is affected by the fixed size of the suspended ceiling keel. If the hanger spacing is changed, the load of the fan, filter, suspended ceiling structure dead load and maintenance live load will cause local suspended ceiling structure to sag or even collapse, which has great safety hidden dangers and affects the subsequent production line production. Therefore, the existing technology needs to avoid the suspended ceiling hanger during the design stage of the mechanical and electrical pipeline routing, and the space management is extremely difficult. It is very difficult to form a one-time construction on site, and the cost of secondary modification is extremely high. SUMMARY
