AI Technical Summary
When installing photovoltaic systems in existing steel structure workshops, the load changes are sensitive, which requires reinforcement of the main structure and purlin system. The installation process may also affect production operations, especially for heavy steel structure workshops where the load exceeds the limit, making it difficult to install existing photovoltaic systems without affecting production.
A truss system is formed by truss columns and roof steel beams. Photovoltaic purlins are installed at an angle above the roof and connected to the roof steel beams through connecting components to avoid direct contact. The load is transferred to the truss system, reducing the impact on the existing purlins. Adhesive and bolt connections are used to avoid welding.
It achieves effective transfer of photovoltaic load, reduces the need to reinforce existing purlins, ensures the safety of the installation process, does not affect factory production operations, and reduces installation costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic installation on steel structure factory buildings, and in particular to a photovoltaic installation structure for steel structure factory buildings. Background Technology
[0002] Distributed photovoltaic (PV) power generation is a new and promising method of power generation and comprehensive energy utilization. It follows the principles of local power generation, local grid connection, local conversion, and local use, effectively increasing the power output of PV power plants of the same scale while also solving the problems of power loss during voltage boosting and long-distance transmission. Currently, the most widely used distributed PV power generation systems are generally built on building rooftops. Steel structure factory roofs, due to their large area and few obstructions, are particularly suitable for installing large-capacity PV power plants. However, due to their structural characteristics, lightweight steel structure factory buildings are sensitive to load changes. Increasing the PV load requires reinforcement of the main structure and purlin system. For ordinary or heavy steel structure factory buildings, the load on the original steel beams often exceeds limits after adding the PV system load, still requiring reinforcement of the original purlin system or steel beams. In addition, photovoltaic systems on the roofs of existing steel structure factory buildings are generally installed after the fact, and there is usually production work inside the factory building during the installation. Therefore, adding photovoltaic systems without affecting normal production inside the factory building is one of the difficulties that need to be overcome in the installation of photovoltaic systems on the roofs of steel structure factory buildings. Summary of the Invention
[0003] In view of this, this utility model proposes a photovoltaic installation structure for tall steel structure factory buildings.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The photovoltaic support structure for tall steel structure factory buildings described in this utility model includes multiple photovoltaic purlins parallel to the roof of the steel structure factory building, multiple rows of truss columns extending outward from the roof of the steel structure factory building, and connecting components for fixing each truss column to the roof steel beam. The truss columns are waterproof and sealed to the roof of the steel structure factory building. Each photovoltaic purlin is fixed to one row of truss columns, so that the photovoltaic purlin is inclined and erected above the roof of the steel structure factory building. The connecting components include a connecting plate and a pair of symmetrically arranged clamping plates. The connecting plate is fixed to the bottom of the truss column and fixed to the roof steel beam through structural adhesive. Each clamping plate has a clamping groove, and the connecting plate and the upper flange plate of the roof steel beam are clamped in the clamping groove. Fastening bolts acting on the upper flange plate are provided on the clamping plate. The beneficial effects are as follows: In this invention, the bottom of the truss column is connected to the roof steel beam to form a truss system. The upper part of the truss column extends above the roof of the steel structure factory building (using color steel tiles) and connects to the photovoltaic purlins. This allows the photovoltaic purlins to be installed above the roof, avoiding contact between the photovoltaic purlins and the roof. This ensures that all loads are transferred to the truss system formed by the truss column and the roof steel beam, reducing the impact on the existing purlins of the steel structure factory building and eliminating the need for reinforcement. Furthermore, the truss column and roof steel beam in this invention are connected by adhesive and bolts, eliminating the need for welding during installation, ensuring high safety, and not affecting production operations within the factory building.
[0005] Preferably, the photovoltaic purlins and each column of the truss are reinforced and connected by diagonal braces arranged in a zigzag pattern, which improves the structural stability of this utility model.
[0006] Preferably, the truss column is a hollow structure. In actual installation, the truss column is preferably made of round or square steel pipe to reduce the amount of steel used and lower the installation cost of the photovoltaic installation structure.
[0007] Compared with the prior art, the advantages of this utility model are: In this invention, the bottom of the truss column connects to the roof steel beam to form a truss system. The upper part of the truss column extends above the roof of the steel structure factory building (using color steel tiles) and connects to the photovoltaic purlins. This allows the photovoltaic purlins to be installed above the roof, avoiding contact between the photovoltaic purlins and the roof. This ensures that all loads are transferred to the truss system formed by the truss column and the roof steel beam, minimizing the impact on the existing purlins of the steel structure factory building and eliminating the need for reinforcement. Furthermore, the truss column and roof steel beam in this invention are connected by adhesive and bolts, eliminating the need for welding during installation, ensuring high safety, and not affecting production operations within the factory building.

[0011] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0012] It should be noted that in the description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0013] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0014] like Figure 1-3 As shown, this utility model proposes a photovoltaic installation structure for tall steel structure factory buildings, including multiple photovoltaic purlins 1 parallel to the roof 2 of the steel structure factory building, multiple rows of truss columns 3 extending outward from the roof 2 of the steel structure factory building, and connecting components for fixing each truss column 3 to the roof steel beam 5. Each truss column 3 is waterproofed and sealed to the roof 2 of the steel structure factory building according to national standards or industry specifications to ensure the waterproof performance of the steel structure factory building. Each photovoltaic purlin 1 is fixed to a row of truss columns 3 (arranged alternately from the top of the roof downwards), so that the photovoltaic purlin 1 is inclined and erected above the roof 2 of the steel structure factory building, and the photovoltaic purlin 1 is vertically parallel to the roof 2 of the steel structure factory building (i.e., the inclination angle of the photovoltaic purlin 1 is consistent with that of the roof 2 of the steel structure factory building). The connecting assembly includes a connecting plate 4a and a pair of symmetrically arranged clamping plates 4b. The connecting plate 4a is fixed to the bottom of the truss column 3 and is fixed to the roof steel beam 5 by structural adhesive. Each clamping plate 4b has a clamping groove. The upper flange plate of the connecting plate 4a and the roof steel beam 5 is clamped in the clamping groove of the clamping plate 4b. The lower clamping part of the clamping plate 4b is provided with a fastening bolt 4c that acts on the upper flange plate to realize the fastening connection between the connecting plate and the roof steel beam.
[0015] During actual installation, the photovoltaic purlins 1 and each row of truss columns 3 are reinforced and connected by diagonal braces 6 arranged in a zigzag pattern to improve structural stability. In addition, the truss columns 3 are hollow structures, and round steel pipes (or square steel pipes) can be used to reduce the amount of steel used and lower installation costs while still meeting load requirements.
[0016] In actual construction, multiple rows of truss columns 3 are installed at intervals on each roof steel beam 5. The steel structure factory building has multiple roof steel beams 5, and the truss columns 3 on the multiple roof steel beams 5 correspond one-to-one, so that the truss columns 3 are distributed in a matrix. Each photovoltaic purlin 1 is fixedly connected to a row of truss columns 3, and the photovoltaic purlin 1 and each row of truss columns 3 are reinforced and connected by diagonal braces 6 arranged in a zigzag pattern to improve structural stability.
[0017] In this invention, the bottom of the truss column 3 is connected to the roof steel beam 5 to form a truss system. The upper part of the truss column 3 extends above the roof 2 of the steel structure factory building (generally using color steel tiles) and connects to the photovoltaic purlin 1, thus allowing the photovoltaic purlin 1 to be installed above the roof, avoiding contact between the photovoltaic purlin 1 and the roof. This ensures that all loads are transferred to the truss system formed by the truss column 3 and the roof steel beam 5, reducing the impact on the existing purlins F of the steel structure factory building and eliminating the need for reinforcement of the existing purlins F. Furthermore, the truss column 3 and the roof steel beam 5 in this invention are connected by adhesive and bolts, eliminating the need for welding during installation, ensuring high safety, and not affecting production operations within the factory building.
[0018] In actual installation, for steel structure factory buildings with a large area and few obstacles, the photovoltaic installation structure of this utility model can be installed on both the north and south slopes, thereby realizing the installation of the photovoltaic system on both the north and south slopes of the steel structure factory building (e.g., Figure 1 As shown in the figure, this improves the utilization rate of solar energy.
[0019] Finally, the above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
