Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic curtain wall crossbeam wiring and construction, and in particular to a unit photovoltaic curtain wall crossbeam wiring and construction method. Background Art

[0002] The existing photovoltaic wiring method is generally to route the cables along the side columns. When the cables are routed to the ceiling elevation area, they are routed through the columns and then enter the upper part of the ceiling area. The overall photovoltaic cable wiring length is long and there are many turning elbows. The unitized curtain wall columns are usually male and female aluminum profile spliced ​​columns, which makes the internal space size of the single-side column smaller than that of the frame column. If conventional photovoltaic cable components and construction processes are used, the following problems will occur:

[0003] The thickness of the photovoltaic connector is 13mm, plus the processing and installation error dimensions. Figure 1 A 15mm gap is required, while the gap size of the unit curtain wall is generally 6-8mm, which cannot accommodate the size of the photovoltaic connector, unless the horizontal dimension of the unit column section is increased by 20mm. However, increasing the cross-sectional dimension of the unit curtain wall column has a greater impact on the indoor visual effect, and architects generally do not agree.

[0004] The turning radius of the photovoltaic cable when passing through the column profile is too small and cannot meet the minimum requirement of R30mm. If the traditional method is used, the cross-sectional width of the curtain wall column must be increased by about 20mm.

[0005] In summary, it is necessary to propose a unit photovoltaic curtain wall beam wiring and construction method to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a unit photovoltaic curtain wall beam wiring and construction method to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A unit photovoltaic curtain wall beam, comprising:

[0009] Two aluminum profile columns;

[0010] An aluminum profile crossbeam, wherein the aluminum profile crossbeam is installed in the middle between two aluminum profile columns, and a photovoltaic glass is installed at the upper and lower ends of the aluminum profile crossbeam and between the aluminum profile columns respectively;

[0011] Intermittent intermediate transfer aluminum profiles, three of which are equidistantly installed inside the aluminum profile crossbeam, a photovoltaic connector is installed in the space formed between every two adjacent intermittent intermediate transfer aluminum profiles, each of which is electrically connected to a cable connector through a photovoltaic cable, and the cable connector is installed at the end of the photovoltaic cable.

[0012] Preferably, an indoor ceiling finish surface is also provided on one side of the exterior of the aluminum profile column, the bottom of the aluminum profile beam and the indoor ceiling finish surface are located on the same horizontal plane, and a decorative aluminum profile cover is installed at the connection between the aluminum profile beam at the indoor ceiling finish surface and the photovoltaic glass.

[0013] Preferably, the intermittent intermediate transition aluminum profile and the aluminum profile cross beam are bonded and fixed by silicone sealant.

[0014] Based on the above-mentioned unit photovoltaic curtain wall beam, the present invention also proposes a unit photovoltaic curtain wall beam wiring construction method, comprising the following steps:

[0015] S1. Aluminum profile crossbeam processing: according to the dimensions shown in the figure, holes are opened on the aluminum profile crossbeam for the passage of photovoltaic cables;

[0016] S2. Unit plate frame assembly: Combine the processed aluminum profile crossbeams and aluminum profile columns to form a unit plate frame, ensuring that the combination is firm and not loose;

[0017] S3. Photovoltaic glass installation: Install the photovoltaic glass to the upper and lower ends of the unit panel frame, fix it to the aluminum profile column and aluminum profile beam, and at the same time, fix the photovoltaic connector in the space inside the aluminum profile beam;

[0018] S4. Photovoltaic cable wiring: Pass the photovoltaic cables and cable connectors from the photovoltaic connector from the outdoor side through the previously processed Φ24mm round holes to the indoor side, and apply glue to seal the photovoltaic cables passing through the round holes to ensure waterproof performance;

[0019] S5. Installation of intermediate transfer aluminum profiles: Install three intermittent intermediate transfer aluminum profiles at equal distances at the front end of the aluminum profile crossbeam. Pay attention to the spacing during installation to avoid collision with the fixed photovoltaic connectors and photovoltaic cables.

[0020] S6. Installation of decorative aluminum profile cover: Install the decorative aluminum profile cover to cover the joints between the aluminum profile crossbeam and the photovoltaic glass, especially the joints at the finished surface of the indoor ceiling. Use silicone sealant to seal the gaps between the photovoltaic glass and the aluminum profile crossbeam and the decorative aluminum profile cover to prevent water leakage;

[0021] S7. On-site installation and commissioning: transport the assembled unit panels to the site, hoist and install them, remove the protective measures on the exposed parts of the photovoltaic cables and cable connectors, complete the connection with the photovoltaic lines in the ceiling, ensure that the labels and names are consistent and the connections are correct, perform necessary commissioning, and ensure the normal operation of the photovoltaic curtain wall beam system.

[0022] Preferably, the hole in step S1 is a circular hole with a size of Φ24 mm.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the present invention designs an intermittent intermediate transfer aluminum profile, which is used for the front end of the beam, effectively expanding the wiring space and avoiding interference with photovoltaic connectors and cables. The upper and lower photovoltaic glass panels share a beam for photovoltaic cable routing, reducing the wiring length and turning elbows, improving connection reliability and reducing costs, reducing the wiring length and turning elbows, reducing installation difficulty and processing costs, and routing using a common beam improves the reliability of photovoltaic cable connection, saves engineering costs and construction time, and solves the problem of later maintenance and replacement. The cross-sectional size of the unit column is not enlarged due to photovoltaic wiring, thereby maintaining the slender beauty of the unit curtain wall. BRIEF DESCRIPTION OF THE DRAWINGS
