Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a staggered construction system for electromechanical pipelines and maintenance walkways. Background Technology

[0002] With the continuous development of science and technology in my country, the demand for the construction of large-scale clean electronic factories is increasing, and the electromechanical pipelines in clean areas are becoming more and more complex. During the construction process, different professional packages are interspersed, making space management extremely difficult. The traditional beam-side anchor rod maintenance walkway construction node is similar to the existing patent CN 215759923U, which directly anchors the hangers separately to construct the maintenance walkway and ceiling panel, forming a single-layer ceiling and maintenance walkway integrated ceiling layer, so as to carry out the maintenance and installation of subsequent fans and filters. Traditional ceiling structures often require secondary demolition and alteration due to delays in securing specialized contractors, changes in design drawings, overlapping work by different contractors, and the need for finished product protection. This results in wasted labor, time, and economic costs. Furthermore, in managing the space for electromechanical pipelines, traditional single-layer cleanroom ceiling structures require comprehensive consideration of the ceiling hanger positions. Since the hanger spacing is affected by the fixed dimensions of the ceiling joists, changes in the hanger spacing can cause localized ceiling structural depressions or even collapses due to loads from fans, filters, the ceiling structure's own weight, and maintenance loads, posing significant safety hazards and impacting subsequent production line commissioning. Therefore, current ceiling construction techniques require the electromechanical pipelines to avoid the ceiling hangers during the design phase, making space management extremely difficult. A single, overlapping on-site construction is very challenging, and secondary demolition and alteration costs are extremely high. Summary of the Invention
