Fabricated building construction quality tracing method, system and device based on blockchain

Abstract

The invention discloses a fabricated building construction quality tracing method, system and device based on a blockchain. The method comprises the steps of obtaining component supply information ofthe fabricated building and design information of the fabricated building, and generating a first bill; generating a second bill according to the node information of each preset quality tracking nodein the prefabricated building construction process; obtaining acceptance record information of the supervisor in the building construction process, and generating a third bill; establishing an assembly type building construction project alliance chain with interconnected and intercommunicated tracing information, and carrying out distributed accounting on the bill; and supervising and tracking theprefabricated building construction quality problem through a unified tracing interface according to a distributed accounting result. By using the method provided by the invention, the quality responsibility problems in the front, middle and later periods of prefabricated building construction can be effectively recorded and traced, a good trust mechanism is established, and the responsibility tracing efficiency is improved. The method can be widely applied to the technical field of buildings.

Description

technical field [0001] The invention relates to the field of construction technology, in particular to a method, system and device for tracing the construction quality of prefabricated buildings based on blockchain. Background technique [0002] Prefabricated building technology is an emerging construction method, which transfers a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory. , transported to the building construction site, and assembled and installed on site through a reliable connection method to complete the building. This technology can not only solve quality problems such as wall cracks and leakage, but also improve the integrity, safety, fire resistance and durability of buildings; prefabricated components can help shorten the construction period through factory production and on...

AI Technical Summary

Problems solved by technology

[0003] However, because there are many types of prefabricated components, the purchase and transportation process is complicated, and there are many participants in the entire prefabricated construction project. Responsibilities are often unclear

The attribution of responsibilities in the early, middle and late stages of construction projects is difficult to divide the contracts signed between some responsible parties, and there is a lack of a good trust mechanism

Moreover, due to the large time span of the project, the emergence of certain uncertain factors will inevitably lead to asymmetry of quality information and mutual prevarication of responsibilities.
