Description

Technical Field

[0001] This utility model relates to the interdisciplinary field of building and new energy, specifically to a prefabricated photovoltaic double-T panel system. Background Technology

[0002] Under the "dual-carbon" strategy, Building-integrated Photovoltaics (BIPV) is an important direction for promoting energy conservation and emission reduction in the building sector. Industrial buildings, due to their large and regular roof areas, are the main battleground for BIPV applications. Currently, the application of photovoltaics on industrial building roofs mainly adopts the "roof-attached" (BAPV) model, which involves adding photovoltaic brackets and modules to the existing roof structure. This model has inherent drawbacks: 1. Poor safety: Drilling during installation damages the roof's waterproof layer, raising questions about connection reliability, insufficient wind resistance, and posing structural safety hazards; 2. Low economic efficiency: Secondary construction increases costs, and the total cost is high throughout the life cycle due to roof maintenance and photovoltaic installation / removal; 3. Weak synergy: The photovoltaic system is disconnected from the building structure and production processes, merely generating electricity without achieving intelligent energy dispatch and deep building integration.

[0003] Therefore, there is an urgent need in this field for a new type of BIPV system that can fundamentally solve structural safety, waterproof reliability, and system integration. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prefabricated photovoltaic double-T panel system, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a prefabricated photovoltaic double-T panel system that solves the problems of poor safety, low economy, and weak synergy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A prefabricated photovoltaic double-T panel system, comprising: Precast double-T slab components, which are prefabricated in the factory, include the double-T slab main body; A prefabricated connection system, comprising a plurality of stainless steel pre-embedded sleeves embedded in the surface of the double-T slab body during the prefabrication process of the slab body; The support system, which is connected to the pre-embedded sleeve by bolts, includes a column and a guide rail fixed on the column; Photovoltaic modules are mounted on the guide rail; The electrical system includes conduits embedded in the double-T plate ribs and cables connecting the photovoltaic modules; An energy management system, whose communication connection is to a data acquisition and monitoring system, is used to optimize the scheduling of system energy based on real-time data.

[0007] Preferably, the embedded sleeve is fixed to the mold by a high-precision positioning system and then cast into shape; the positioning system includes a CNC-machined hole on the double T-plate steel side mold, a positioning pin pressed into the hole, and an embedded sleeve sleeved on the positioning pin.

[0008] Preferably, the system further includes a core waterproof node, which comprises: The first flexible waterproof layer is applied to the joint between the root of the embedded sleeve and the cast-in-place roof layer. The second layer of waterproof membrane is an additional membrane that is fitted onto the pre-embedded sleeve and fully bonded and welded to the main roof waterproof layer; The third mechanical seal is a stainless steel waterproof base that is pressed onto the pre-embedded sleeve by silicone sealant and EPDM gasket.

[0009] Secondly, the present invention provides a construction method for the above-mentioned system, comprising the following steps: Digital design phase: Through BIM integrated collaborative design, the three-dimensional coordinates of each embedded sleeve are accurately defined, and structural safety and power generation performance simulations are performed; Prefabrication stage: The embedded sleeve is fixed on the double-T panel mold by a positioning system, concrete is poured, and after curing and demolding, the prefabricated photovoltaic double-T panel component is formed. On-site integration phase: hoisting double T-slabs, constructing cast-in-place layers, installing triple waterproofing joints, installing bracket systems and photovoltaic modules, and integrating electrical systems; Intelligent operation and maintenance phase: Real-time monitoring of operational data through data acquisition and monitoring systems, and intelligent optimization and scheduling through energy management systems.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model features structural integration: the stress connection points of the photovoltaic system are permanently integrated with the main building structure during the factory prefabrication stage, achieving a "bones-and-flesh connection" and fundamentally solving the problems of structural safety and wind resistance.

[0011] Eliminating the risk of leakage: The innovative "triple waterproofing node" design, through progressive protection of flexible sealing, rolled material reinforcement and mechanical compression, completely solves the problem of roof leakage in the BAPV model.

[0012] Economic efficiency throughout the entire life cycle: It avoids secondary construction and subsequent maintenance, is quick to install, and improves power generation revenue through smart energy management, thus achieving optimal cost and maximum value throughout the project's life cycle.

[0013] The integration of industrialization and digitalization has enabled the digitalization and industrialization of the entire process from design and production to construction and operation and maintenance. This results in controllable quality and improved efficiency, making it a model of deep integration of intelligent construction and green building. Attached Figure Description
