[pipeline reservation and embedding] for the main construction of precast buildings
Text: in the cast construction projects of indemnificatory housing constructed in China, a large number of them still follow the construction method of embedding electrical piping in cast-in-situ floor slab and PC components.
The separation design of electrical piping and building structure system is a better solution.
However, if only the separation design of equipment pipeline and structure main body is adopted instead of integrating equipment pipeline into building structure system through new technical measures, it is still contrary to the standardized and modular design concept emphasized by precast buildings.
It skillfully divides and assembles the electrical pipelines installed in the floor slab, which not only meets the requirements of standardized and modular construction of precast residential electrical piping, but also reduces the embedded workload of on-site construction personnel, It provides a new design idea for the implementation of integrated design of electrical pipelines in the same type of cast building projects in the future…
The emergence of the electrical piping technology of the integrated floor (double-layer floor) in which the electrical pipelines are precast in the double-layer floor slab solves this problem better.
The embedded positions of piping and junction box are relatively fixed, which is not conducive to the maintenance and replacement of equipment.
