Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building engineering, and in particular to an intelligent prefabricated building construction method. Background Art
[0002] Prefabricated construction is a new type of construction method in which building components are prefabricated in factories and then transported to the site for assembly. It has the advantages of fast construction speed, low environmental pollution, and controllable quality. It is being used more and more widely in various construction projects.
[0003] In the field of construction engineering technology, traditional construction progress management mainly relies on manual records and experience judgment, which makes it difficult to grasp the progress of each construction link in real time and accurately. In prefabricated building construction, it involves the production, transportation and installation of many prefabricated components. Manual management methods are prone to delays. For example, if prefabricated components fail to arrive at the construction site on time or the installation sequence is unreasonable, it will affect the overall construction progress.
[0004] Prefabricated buildings rely on the precise installation of prefabricated components. However, in actual construction, the accuracy of component installation is difficult to ensure due to factors such as production errors of prefabricated components and measurement deviations at the construction site. Prefabricated building construction involves multiple links such as design, production, transportation and construction. Information flow between links is not smooth, and collaborative work efficiency is low. The identification of prefabricated buildings at the construction site is unclear, making it difficult to quickly locate the required prefabricated buildings, which increases the time for searching and transporting. At the same time, due to the lack of real-time monitoring, the status and location of prefabricated buildings cannot be grasped in time, and they are prone to loss, affecting the construction progress. In addition, some quality problems are not discovered until the later stages of construction, with high rectification costs, and may even affect the overall safety of the structure. Summary of the invention

If MTAI < MTAI0, it means that the construction status tracking of the i-th prefabricated component is abnormal, and a warning signal of abnormal construction status tracking is issued and a construction status tracking management mechanism is triggered. The prefabricated building prefabricated components with abnormal construction status tracking are managed through a unique identifier, such as checking whether the identifier is damaged, whether the reading and writing equipment is faulty, etc. Otherwise, it is normal; then compare the construction transportation efficiency tracking index TETI of the i-th prefabricated component with the threshold TETI0.

The prefabricated components of prefabricated buildings with abnormal production dimensions are managed through unique identification, such as checking whether the production process parameters are set incorrectly and whether the raw material dimensions meet the requirements. Otherwise, it is normal. Then, the production welding quality index WQI of the i-th prefabricated component is compared with the threshold WQI0.

If CQI<CQI0, it means that the assembly connection quality of the prefabricated components of the prefabricated building is abnormal. An abnormal assembly connection quality warning signal is issued and the assembly connection quality management mechanism is triggered. The prefabricated components of the prefabricated building with abnormal assembly connection quality are managed through a unique identifier, such as redesigning the connection nodes to ensure a reasonable structure. Otherwise, it is normal. S5: Human-computer interaction is carried out based on the warning signal issued by S4 and the corresponding management mechanism. The management mechanism includes the identification of prefabricated components of prefabricated buildings, abnormal results and corresponding management measures. For example, during the construction of the i-th prefabricated component of the prefabricated building, the system detects that the transportation efficiency tracking indicator TETI=0.75 is lower than the threshold TETI0=0.80. The system issues a warning signal for abnormal transportation efficiency tracking and locates the prefabricated component numbered M-456 involved in the abnormal transportation task; the reason for the abnormality is that the inspection found that the transportation route of prefabricated component M-456 was delayed due to traffic congestion; the management measure is that the system adjusts the transportation route in real time to avoid congested sections, and the transportation vehicles drive along the new route and finally arrive at the assembly site on time; management result: the system recalculates TETI, and the result is 0.82, which is higher than the threshold TETI0, and the transportation efficiency returns to normal.
