Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and specifically provides a modular design platform for green and energy-saving prefabricated buildings. Background Art

[0002] The modular design platform for prefabricated buildings is a system platform based on modularity, leveraging advanced design and information technology to enable rapid, standardized, and customized construction. It breaks down buildings into standardized modular units and employs industrialized manufacturing methods, significantly shortening construction cycles and improving efficiency. Through this platform, designers can quickly adjust and combine modules based on project requirements, providing flexible design solutions. Digital technology is also used for virtual modeling and simulation to ensure design accuracy and constructibility. This platform not only optimizes building structures and reduces on-site construction workload, but also effectively improves resource utilization and reduces construction costs.

[0003] In pursuit of production and installation efficiency, traditional platforms force the use of fixed-size modules. However, actual buildings must dynamically adjust insulation / shading strategies based on orientation and climate zoning, resulting in passive compromises in energy-saving design. Continuous thermal bridges are formed at module joints due to standardized assembly (such as exposed steel connectors). The measured heat loss is 10%-15% higher than that of cast-in-place buildings. The insulation layer is cut at the edge of the module, forming discontinuous insulation zones, and the cold and hot bridge effect is significant. Large windows are required to capture solar radiation heat from the south, and small windows are required to reduce heat dissipation from the north. However, standardized modules require a uniform window opening ratio, which cannot be optimized on demand. The fundamental reason is that the modular platform is designed for assembly logic, which prioritizes factory production and transportation efficiency, and does not incorporate building physical properties as core parameters into the design phase.

[0004] At the same time, traditional platforms design structural modules and energy equipment (photovoltaic panels, ground-source heat pumps, etc.) as independent systems, resulting in low integration of renewable energy and equipment space occupying structural space. Summary of the Invention

[0005] The purpose of the present invention is to provide a green and energy-saving modular design platform for prefabricated buildings to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a modular design platform for green and energy-saving prefabricated buildings, comprising the following modules:

[0020] Three-dimensional pipeline channel system, with gradient aperture casing embedded in the load-bearing wall;

[0023] The main pipeline casing that runs through the longitudinal direction has a hole diameter of 120mm; the branch line casing arranged horizontally has a hole diameter of 40mm; this casing system automatically forms a pipeline channel network when the modules are assembled.

[0024] As a further technical solution of the present invention, the photovoltaic roof panel module adopts conductive adhesive embedded circuit technology to embed the wires into the concrete protective layer; this structure has both waterproof and load-bearing functions and photovoltaic power generation functions.

[0025] As a further technical solution of the present invention, the performance simulation optimization central module includes:

[0026] Multi-physics simulator that simultaneously runs building thermal calculations, photovoltaic power generation predictions, and airflow analysis;

[0027] Intelligent optimization decision tree, used to generate structural optimization instructions based on simulation results;

[0028] Low-carbon material evaluator, used to compare the embodied carbon emissions of materials.

[0029] As a further technical solution of the present invention, the intelligent optimization decision tree is configured as follows:

[0030] When a thermal bridge is detected, the command to add a thermal bridge-breaking plug is triggered. When a ventilation dead corner is found, the command to embed an induced ventilation cavity is triggered. The thermal bridge-breaking plug is made of graphene aerogel composite material with a heat transfer coefficient not exceeding 0.01W / (m·K).

[0031] As a further technical solution of the present invention, the smart construction management module includes:

[0032] Digital twin monitoring system, used to laser scan module assembly errors and generate tolerance compensation models;

[0033] Energy adaptation dashboard, used to monitor energy consumption data in real time and trigger operation and maintenance strategies;

[0036] Generate customized module parameters through a climate-driven design engine;

[0037] Creating an integrated model from the structure-energy synergy module;

[0038] Optimize the hub through performance simulation to verify the model's compliance status;

[0039] If the standards are not met, the adjustment parameters will be returned. If the standards are met, the smart construction management module will execute the construction.

[0040] After construction is completed, operational data is collected and fed back to the design starting point;

[0041] Verification of the model's compliance status includes thermal parameter testing, photovoltaic power generation efficiency verification, and structural strength testing.

[0042] The beneficial effects of the present invention are as follows:

[0043] (1) This invention transforms a building into an organic system with adaptive capabilities through a dynamic matching mechanism between physical properties and climate environment. The climate-driven design engine converts environmental parameters such as solar radiation intensity and prevailing wind direction into specific structural parameters of the enclosure structure in real time, enabling the south-facing module to automatically enhance its light transmission and heat storage capacity and the north-facing module to autonomously thicken its insulation layer, thus completely eliminating energy losses caused by orientation differences. The performance simulation and optimization center continuously monitors the actual operating status of the building. When the thermal sensor identifies a local thermal bridge effect, the system immediately triggers the intelligent embedding of the thermal bridge-breaking plug module. When the airflow sensor detects a ventilation dead corner, it automatically generates structural instructions for inducing the ventilation cavity, significantly reducing the energy consumption of traditional prefabricated buildings and achieving green energy conservation.

[0044] (2) The present invention creates a new carrier value through structural fusion technology. The photovoltaic roof panel module completes the implantation of conductive adhesive circuits during the concrete pouring stage, making the roof a power generation unit, waterproof layer and structural load-bearing body at the same time. Actual measurements show that this structure reduces the roof construction cost by 40% and extends the service life by about eight years. The three-dimensional pipeline channel system pre-buries the casing network during the prefabrication stage. During construction, only the cables need to be inserted to form a complete energy circuit, which reduces the consumption of copper by three tons compared with traditional grooving wiring. More importantly, the module recycling and traceability chain gives building materials a second life. When dismantled, the chip automatically identifies the reusable photovoltaic chip and titanium alloy heat exchange tube, and matches the needs of new projects through blockchain, significantly reducing carbon emissions in the production process and further improving energy efficiency.

[0091] Different from the above-mentioned embodiment, the second embodiment is an in-situ forming system for the energy structure unit of an assembled building;

[0092] 1. Photovoltaic-enclosure integrated prefabricated unit

[0093] The physical integration of the PV system into the building envelope is completed during the factory prefabrication phase, which includes the following steps:

[0094] Step 1: Within 30 minutes after the concrete is vibrated and formed, pour liquid thermal conductive adhesive into the module interlayer. The thermal conductive adhesive is a composite of nano-alumina and silicone resin, with a thermal conductivity coefficient of ≥3.5W / (m·K);

[0095] Step 2: Use a six-axis robotic arm to lay out the photovoltaic chip array before the colloid solidifies, and control the chip spacing tolerance within ±0.2mm;

[0096] Step 3: Self-cleaning tempered glass is laminated onto the chip surface using a hot pressing device at a temperature of 120°C and a pressure of 5 MPa. The glass surface is coated with a titanium dioxide photocatalytic coating.

[0097] Step 4: The molded modules are transported after load-bearing test and electrical safety test, where the load-bearing capacity is ≥1.5kN / m² and the insulation resistance is ≥10MΩ.

[0098] 2. Ground source heat pump-pile foundation collaborative components

[0099] Achieve simultaneous construction of the pile foundation structure and the ground-source heat pump system, specifically including:

[0100] The pile body adopts a hollow spiral structure with double-channel titanium alloy heat exchange tubes embedded inside. The specifications of the heat exchange tubes are 40mm inner diameter and 2mm wall thickness.

[0101] The composite phase change material layer on the outer wall of the heat exchange tube is composed of a paraffin matrix and 15% by mass of graphene nanosheets, with a phase change latent heat of ≥180kJ / kg;

[0102] During construction, the pile holes are first drilled, and a special mortar with a thermal conductivity of 1.2W / (m·K) is injected. Then the prefabricated heat exchange piles are spin-pressed and implanted.

[0103] An expandable alloy wing plate is set at the bottom of the pile body, which automatically expands to twice the pile diameter when reaching the designed depth, expanding the contact surface and enhancing heat exchange.

[0104] 3. Energy unit self-organizing network method

[0105] Autonomous energy interconnection between modules is achieved through structural joints:

[0106] Silver-copper alloy conductive glue is applied to the module joints, with silver-copper particles accounting for 80% by mass and a volume conductivity of ≥5×10 7 S / m;

[0107] The conductive adhesive is embedded with a micro communication chip, the chip model is nRF52840, which automatically identifies the polarity of adjacent module circuits;

[0108] Each module transmits operating parameters to the edge computing gateway via the LoRa protocol. The gateway's main control chip uses Rockchip RK3399.

[0109] The system has a displacement compensation function, and can maintain a stable electrical connection when the relative displacement of the modules is ≤5mm.

[0110] 4. Technical effect verification

[0111] After the implementation of a prefabricated housing project, it was measured that:

[0112] The daily power generation of the photovoltaic unit increased by 19%, and the peak operating temperature decreased by 22°C;

[0113] The heating power of a single heat exchange pile reaches 4.5kW in winter, which is 60% higher than that of traditional systems.

[0114] The energy network installation period is shortened to 1 / 3 of the traditional wiring method;

[0115] The module joint resistance attenuation rate is still ≤5% after two years.

[0116] By dynamically matching physical properties with the climatic environment, the building is transformed into an organic, adaptive system. The climate-driven design engine converts environmental parameters such as solar radiation intensity and prevailing wind direction into specific structural parameters for the building envelope in real time. This allows south-facing modules to automatically enhance their light transmission and heat storage capabilities, while north-facing modules autonomously thicken their insulation layers, completely eliminating energy losses caused by orientation differences. The performance simulation and optimization center continuously monitors the building's actual operating status. When thermal sensors identify localized thermal bridge effects, the system immediately triggers the intelligent insertion of thermal bridge-breaking inserts. When airflow sensors detect ventilation blind spots, structural instructions are automatically generated to induce ventilation cavities, significantly reducing the energy consumption of traditional prefabricated buildings and achieving green energy conservation.

[0117] By using structural fusion technology to create new carrier value, the photovoltaic roof panel module completes the implantation of conductive adhesive circuits during the concrete pouring stage, making the roof a power generation unit, waterproof layer and structural load-bearing body at the same time. Actual measurements show that this structure reduces roof construction costs by 40% and extends the service life by about eight years. The three-dimensional pipeline channel system pre-buries a casing network during the prefabrication stage. During construction, only cables need to be inserted to form a complete energy circuit, which reduces copper consumption by three tons compared to traditional grooving wiring. More importantly, the module recycling and traceability chain gives building materials a second life. During dismantling, the chip automatically identifies the reusable photovoltaic chips and titanium alloy heat exchange tubes, and matches new project requirements through blockchain, significantly reducing carbon emissions in the production process and further improving energy efficiency.
