Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction technology, and more particularly to a BIM-based prefabricated building intelligent construction system. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods. Prefabricated buildings can significantly improve production efficiency, save production costs, and have the advantages of energy saving and environmental protection. However, prefabricated buildings not only need to ensure that the quality and standards of prefabricated components meet the design requirements, but the construction process also needs to ensure construction specifications, and the requirements for the quality of construction work are higher. Therefore, construction process management is very important for the construction of prefabricated buildings. Traditional construction management solutions mainly manage the construction site and cannot achieve comprehensive construction management, resulting in low construction efficiency. In addition, the component production process of prefabricated buildings also needs to be controlled. Traditional construction management solutions are no longer applicable to prefabricated building construction. Therefore, how to provide a BIM-based prefabricated building intelligent construction system is a problem that technicians in this field urgently need to solve. Summary of the Invention

[0003] In view of this, the present invention provides a BIM-based intelligent construction system for prefabricated buildings, which comprehensively manages the component production, construction plan and construction process of prefabricated buildings, improves construction efficiency, ensures construction quality and reduces construction risks.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the present invention discloses a BIM-based intelligent construction system for assembled buildings. Figure 1 Shown, including:

[0023] The component planning module plans the prefabricated component data based on the design data of the prefabricated building to be constructed, obtains the required types and quantities of prefabricated components, and plans the production plan for prefabricated components;

[0024] Digital modeling module, which creates a BIM model of a prefabricated building composed of prefabricated components. The BIM model is used to plan construction plans, guide subsequent construction, and monitor construction progress;

[0025] A construction planning module that plans the construction plan of the prefabricated building to be built based on the design data of the prefabricated building to be built and the prefabricated component data;

[0026] The intelligent construction module controls the operation of construction equipment in each process according to the planned construction plan of prefabricated buildings;

[0027] Visualization module, used to visualize the BIM model and data during the construction process.

[0028] Furthermore, the component planning module determines the types and quantities of prefabricated components required based on the design data of the prefabricated building to be constructed, takes the lowest total production cost and the shortest total production time as the production plan planning goals for the prefabricated components, and calculates the optimal production plan for the required quantity of all prefabricated components based on actual production data.

[0029] In an embodiment of the present invention, production cost and production time calculation models for prefabricated components are established respectively. The production cost takes into account the material cost, processing cost, labor cost, warehousing cost and transportation cost of each process. The production time is calculated based on the production resources of each process and the factory, and then solved by genetic algorithm to obtain the optimal production plan.

[0030] Furthermore, the digital modeling module establishes a BIM model of each prefabricated component according to the design plan of the prefabricated component, associates and synchronizes the prefabricated component with the BIM model, and updates the BIM model based on the construction progress during the construction process. The construction data is imported to modify the BIM model, and the BIM model is transmitted to the visualization module for visual display.

[0031] In an embodiment of the present invention, during the design phase of an assembled building, data such as the building's design drawings are obtained, three-dimensional modeling is performed using 3Dmax software, and upon completion, the model is imported into Revit software for BIM model construction to obtain a BIM building model. In the digital modeling module, assembled components are linked and synchronized with their BIM models. During construction, the quality inspection data, risk monitoring data, and construction progress data of the assembled components are synchronously transmitted to the database of the visualization module. In the visualization module, the relevant data of the assembled components can be updated synchronously with the construction progress. If the quality inspection data of the assembled components fails, this can be displayed in the visualization module.

[0032] Furthermore, the construction planning module plans the installation process of each prefabricated component based on the BIM model of the prefabricated components, determines the connection relationship between each prefabricated component, checks and optimizes the collision points and reserved pipeline points between each prefabricated component. After the construction process planning is completed, the construction planning module can reproduce the planned construction process based on the BIM model.

[0033] The reserved pipelines in prefabricated buildings serve multiple purposes, and errors, omissions, and gaps can occur during the design phase. Therefore, by planning construction plans based on BIM models and rehearsing the construction, we can identify design changes or upcoming construction issues that may need to be made during the actual construction process and optimize and resolve them. After optimization, simulations continue, forming a process of simulated construction and problem-solving until all foreseeable issues in the construction planning process are resolved. Finally, this process is used to guide actual construction, reducing the possibility of problems arising during subsequent actual construction and ensuring the smooth progress of the prefabricated building construction process.

[0034] Furthermore, the smart construction module is connected to the data acquisition equipment and construction equipment at the construction site. According to the planned construction plan and the current construction progress, the smart construction module controls the operation of the data acquisition equipment and construction equipment corresponding to the current construction progress.

[0035] Furthermore, the visualization module includes a display unit, a database, and a query unit. The database is used to store construction planning data, construction schedule data, prefabricated component quality inspection data, and risk monitoring data during the construction process. The display unit is used to display the BIM model of the prefabricated building and visualize data charts. The query unit is used to query data in the database. The query unit can query data in the database based on date, prefabricated component, data type, and other methods, facilitating the comprehensive management of construction projects.

[0036] Furthermore, it also includes a risk monitoring module, which collects construction progress data and construction environment data during the construction process, evaluates possible risks in the construction process based on the data, and issues an alarm when risks are detected.

[0037] Furthermore, the risk monitoring module is composed of monitoring equipment, early warning equipment, alarm equipment and data transmission equipment. Among them, the monitoring equipment includes cameras, thermometers, pressure sensors, smoke sensors, electronic levels, electronic rangefinders, vibration sensors and voltage detection equipment. The monitoring equipment collects corresponding monitoring data and transmits it to the early warning equipment. The early warning equipment determines whether there is a construction risk based on the monitoring data. The alarm equipment issues an alarm based on the construction risk through an audible and visual alarm. The data transmission equipment transmits the monitoring data to the visualization module.

[0038] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
