Description

Technical Field

[0001] The present invention relates to the field of prefabricated building components, and in particular to a building system based on prefabricated buildings. Background Art

[0002] With the development of modern industrial technology and the continuous improvement of the design and construction level of buildings, the structure and function of buildings have gradually become diversified. In order to improve the construction efficiency of buildings, prefabricated building structures have gradually come into people's view. In prefabricated buildings, only the house components required for the building need to be prefabricated in advance and assembled on the construction site. Due to the fast construction speed and low production cost of prefabricated buildings, they have been widely recognized and quickly popularized around the world. When constructing prefabricated buildings, in order to improve the efficiency and accuracy of the construction content during the construction of prefabricated buildings, in the prior art, a building system for prefabricated buildings is designed to manage the data and construction content during the construction of prefabricated buildings.

[0003] At present, when prefabricated buildings are being constructed, they are all assembled and spliced by using prefabricated building modules. The advantages are that the construction is simple, the construction efficiency is high, and a large amount of material waste is also prevented. However, for prefabricated buildings, since all the standard parts used are prefabricated in advance, if these standard parts do not meet the performance requirements such as earthquake resistance and wind resistance, it will affect the quality of the overall building. And because the positions where different standard parts are used are different, their bearing capacities and stabilities under different swing amplitudes are different, and the standard parts cannot be manufactured according to the same process completely.

[0004] Therefore, there is an urgent need for a technology to replace the existing assembly method to solve the problems of how to improve the structural stability and environmental protection of prefabricated buildings. Summary of the Invention

[0005] The embodiments of the present application provide a building system based on prefabricated buildings, thereby solving the problems in the related art of how to improve the structural stability and environmental protection of prefabricated buildings.

[0006] Among them, a building system based on prefabricated buildings provided by the embodiments of the present application includes:

[0007] A building design module is used to design prefabricated building components. The building design module performs three-dimensional visualization design through BIM technology and generates a prefabricated building model;

[0008] The building design module includes a safety review unit, which uses structural analysis software to conduct safety reviews on the designed building components and the constructed model. The reviewed items include: material strength, reinforcement design, joint strength, waterproof performance, bearing capacity, deformation performance, and seismic performance;

[0009] Record the safety audit data as Ai, where i = 1, 2, …, 7;

[0010] The safety audit data Ai is the safety value of the i-th item to be audited, including: material strength A1, reinforcement strength A2, joint strength A3, waterproof performance A4, load-bearing capacity A5, deformation performance A6, and seismic performance A7;

[0011] Preset an outlier determination threshold X, where X > 0;

[0012] When Ai > X, it is determined that the safety index of the designed building components and the constructed model meets the standard;

[0013] When Ai ≤ X, it is determined that the safety index of the designed building components and the constructed model does not meet the standard;

[0014] The production module is used to purchase raw materials and produce and process precast components according to the design drawings, and inspect and accept the finished products;

[0015] The assembly module is used to complete the assembly of precast components. The assembly module uses high-precision installation positioning tools to position and assemble the components, and uses special connecting components and grouting techniques to connect the components;

[0016] The quality monitoring module is used to strictly monitor the quality of the production module and the assembly module, establish a quality monitoring information unit, and collect, store, and analyze the quality information of the prefabricated building in real time.

[0017] Furthermore, the building design module optimizes and improves the designed building components and the constructed model that do not meet the normal safety indicators, and conducts another safety audit; the building design module includes a drawing generation system for converting the prefabricated building design content into drawing information.

[0018] Furthermore, the building design module also includes an intelligent assistance system for optimizing the design scheme of the prefabricated building; the intelligent assistance system learns from a large number of prefabricated building cases through machine learning technology, extracts design experience and rules, and uses these experiences and rules to assist designers in design, providing design suggestions and reference schemes.

[0019] Furthermore, the production module adopts green production technology. In terms of energy management: by installing an energy monitoring system, analyzing the detailed energy consumption during the production process, and upgrading and transforming the equipment, an intelligent standby mode is adopted, so that the equipment automatically enters a low-power state when not working; in terms of raw material recycling: a perfect waste recycling and treatment workshop is established. For the concrete surplus materials, after treatment, they are made into recycled aggregates and used for the production of non-load-bearing precast components.

[0020] Furthermore, the assembly module can perform different types of assembly according to the existing situation, including factory assembly and on-site assembly; the factory assembly directly assembles the fabricated components and transports the assembled building components to the assembly site; the on-site assembly first transports the fabricated components to the assembly site and then conducts on-site assembly.

[0021] Furthermore, after the overall installation of the prefabricated building is completed, a comprehensive quality acceptance is carried out. The acceptance content includes the structural performance, waterproof performance, and insulation performance of the building. Only the prefabricated building that passes the acceptance can be delivered for use; and a structural load test is conducted on the prefabricated building to check the structural safety of the building under normal use and special situations such as earthquakes; a waterproof test is carried out on parts such as the roof and exterior walls of the building to ensure that the waterproof performance of the building meets the requirements.

[0022] Furthermore, the quality monitoring information unit includes a data acquisition module, a data storage and quality traceability module.

[0023] Furthermore, the data acquisition module is used to collect data on the production process and assembly process and conduct real-time monitoring based on sensors.

[0024] Furthermore, the data storage module establishes a database, stores the collected quality data in the database, classifies and archives the quality data, stores it by different links, and also classifies and manages different types of precast components for easy query and statistics.

[0025] Furthermore, the quality traceability module includes tracing the production process and tracing the transportation and assembly process;

[0026] Tracing the production process: Record the data of each link in the production process of precast components, including the use of molds, steel bar processing technology, and concrete pouring time. When quality problems occur, it can be traced back to specific production links to find the root cause of the problems;

[0027] Tracing the transportation and assembly process: Record the transportation and assembly process of precast components, including transportation vehicle information, installation location, and connection method. When quality problems are found, it can be traced back to the transportation and assembly links to determine the responsible party for the problems.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. The building design module uses BIM technology for three-dimensional visualization design, which can intuitively present the appearance, internal structure, and relationships between components of the prefabricated building. This helps designers understand the design scheme more comprehensively and deeply, discover and solve potential design conflicts or unreasonable points in a timely manner, thereby optimizing the building design and improving the accuracy and integrity of the design;

[0030] 2. The safety audit unit uses structural analysis software to conduct multi-faceted safety audits on the designed building components and the constructed model, covering key items such as material strength, reinforcement design, joint strength, waterproof performance, load-bearing capacity, deformation performance, and seismic performance. By comparing each safety value with the preset abnormal value judgment threshold, the safety of the design can be accurately judged. This comprehensive and detailed audit mechanism can effectively avoid building safety hazards caused by design defects, ensure the structural safety and performance stability of the building during subsequent construction and use, and provide a reliable living and using environment for users.

[0031] 3. The quality monitoring module conducts strict quality monitoring on the production module and the assembly module. By establishing a quality monitoring information unit, it can collect, store, and analyze the quality information of prefabricated buildings in real time. This enables quality problems to be detected and corresponding measures to be taken for solution in a timely manner at all stages of building construction. Real-time monitoring helps to control quality problems in the bud, avoid the accumulation and deterioration of problems, and thus effectively guarantee the overall quality of the building.

[0054] When Ai ≤ X, it is determined that the safety index of the reviewed designed building components and the constructed model does not meet the standard.

[0055] The production module is used to purchase raw materials and produce and process precast components according to the design drawings, and inspect and accept the finished products.

[0056] The assembly module is used to complete the assembly of precast components. The assembly module uses high-precision installation positioning tools to position and assemble the components, and uses special connecting components and grouting techniques to connect the components.

[0057] The quality monitoring module is used to strictly monitor the quality of the production module and the assembly module, establish a quality monitoring information unit, and collect, store, and analyze the quality information of the prefabricated building in real time.

[0058] Specifically, the building design module conducts three-dimensional visualization design through BIM technology and generates a prefabricated building model. It purchases raw materials based on the designed building model and produces and processes precast components according to the design drawings, inspects and accepts the finished products. During assembly, high-precision installation positioning tools are used to position and assemble the components, and special connecting components and grouting techniques are used to connect the components to complete the assembly of precast components. It strictly monitors the quality of the production module and the assembly module, establishes a quality monitoring information unit, and collects, stores, and analyzes the quality information of the prefabricated building in real time.

[0059] It can be understood that through three-dimensional visualization design using BIM technology to generate a prefabricated building model, and the collaborative effects in the procurement, production, assembly, and quality monitoring links, it can significantly improve the design accuracy, production quality, assembly accuracy, and quality monitoring level of prefabricated buildings, providing a strong guarantee for the sustainable development of prefabricated buildings.

[0060] Specifically, the building design module optimizes and improves the designed building components and construction models that do not meet the normal safety indicators, and conducts another safety review; the building design module includes a drawing generation system for converting the prefabricated building design content into drawing information.

[0061] It can be understood that optimizing and improving the designed building components and construction models that do not meet the normal safety indicators can timely discover and correct potential safety hazards. By making targeted adjustments to the problematic parts, the stability, seismic performance and other key safety indicators of the building structure can be improved. The re-safety review further ensures that the optimized design meets the safety requirements. After multiple reviews, errors and loopholes in the design can be minimized to improve the reliability of building design. This rigorous safety review mechanism provides a solid guarantee for the long-term stable operation of the building.

[0062] Specifically, the building design module also includes an intelligent assistance system for optimizing the design scheme of prefabricated buildings; the intelligent assistance system learns from a large number of prefabricated building cases through machine learning technology, extracts design experience and rules, and uses these experiences and rules to assist designers in design, providing design suggestions and reference plans.

[0063] Specifically, the intelligent assistance system can optimize the design scheme of prefabricated buildings. By analyzing the experiences and rules extracted from a large number of cases, the design can be improved in multiple aspects. The design experiences and rules learned by machine learning technology can help designers avoid some common design mistakes. Moreover, the intelligent assistance system can quickly provide design suggestions and reference plans during the design process of designers. Designers do not need to conceive the design from scratch, but can adjust and optimize based on what the system provides, greatly shortening the design time.

[0064] It can be understood that the intelligent assistance system in the building design module provides designers with optimized design schemes, quick suggestions and references through learning a large number of prefabricated building cases, improves the design quality and efficiency, and also promotes design innovation and industry development.

[0065] Specifically, the production module adopts green production technology. In terms of energy management: by installing an energy monitoring system, conducting a detailed analysis of energy consumption during the production process, upgrading and transforming the equipment, and adopting an intelligent standby mode, the equipment automatically enters a low-power state when not working; in terms of raw material recycling: establishing a perfect waste recycling and treatment workshop, for the surplus concrete, after treatment, it is made into recycled aggregate for the production of non-load-bearing precast components.

[0066] It is understandable that after the equipment is upgraded and transformed and adopts the intelligent standby mode, when the equipment is not working, it can automatically enter the low-power state, which directly reduces the energy consumption of the equipment during the idle period. For the production module, the accumulated standby energy consumption of numerous equipment over a long period of time is a significant expense, and this measure can effectively reduce this part of the cost. Moreover, by establishing a perfect waste recycling and treatment workshop, recycling the concrete leftovers and processing them into recycled aggregates for the production of non-load-bearing precast components, the recycling and reuse of raw materials are realized. The concrete leftovers that might have been treated as waste originally regain their utilization value, greatly improving the utilization rate of raw materials and reducing the demand for new raw materials.

[0067] Specifically, the assembly module can perform different types of assembly according to the existing situation, including factory assembly and on-site assembly; factory assembly directly assembles the fabricated components and transports the assembled building components to the assembly site; on-site assembly first transports the fabricated components to the assembly site and then performs on-site assembly.

[0068] Specifically, after the overall installation of the prefabricated building is completed, a comprehensive quality acceptance is carried out. The acceptance content includes the structural performance, waterproof performance, and thermal insulation performance of the building. Only the prefabricated building that passes the acceptance can be delivered for use; and a structural load test is carried out on the prefabricated building to check the structural safety of the building under normal use and special situations such as earthquakes; a waterproof test is carried out on parts such as the roof and exterior walls of the building to ensure that the waterproof performance of the building meets the requirements.

[0070] Specifically, the quality monitoring information unit includes a data acquisition module, a data storage and quality traceability module. The data acquisition module is used to collect data on the production process and assembly process and perform real-time monitoring based on sensors.

[0071] Specifically, the data storage module establishes a database, stores the collected quality data in the database, classifies and archives the quality data, stores them classified according to different links, and also classifies and manages different types of precast components for easy query and statistics.

[0072] Specifically, the quality traceability module includes tracing the production process and tracing the transportation and assembly process;

[0073] Trace the production process: Record the data of each link in the production process of precast components, including the use of molds, steel bar processing technology, and concrete pouring time. When quality problems occur, it is possible to trace back to the specific production link and find out the root cause of the problem;

[0074] Trace the transportation and assembly process: Record the transportation and assembly process of precast components, including transportation vehicle information, installation location, and connection method.
