Description

Technical Field

[0001] The utility model relates to the field of architecture, and particularly to an assembled photovoltaic curtain wall structure. Background Art

[0002] In the long development history of architecture, modern buildings increasingly use glass curtain wall materials to replace traditional building enclosure walls. However, with the gradual increase in attention to building energy consumption and green energy conservation, the significant energy consumption loss problem of glass curtain walls cannot be ignored. At the same time, more and more high-rise buildings use unitized curtain wall systems, in which the upper and lower frames (left and right frames) of each unit component are inserted into each other to form combined bars, completing the joints between unit components and thus forming an overall curtain wall. Such an overall curtain wall has the following disadvantages:

[0003] 1. If the unit curtain wall panels need to be repaired or replaced after installation, it will be relatively difficult.

[0004] 2. The direct connection of unit components to each other easily causes a chain reaction, affecting the stability of the overall curtain wall.

[0005] 3. The heat dissipation of ordinary photovoltaic curtain walls easily causes the indoor temperature to rise and at the same time shortens the service life of its own materials, and it is greatly affected by sunlight. Content of the Utility Model

[0006] The purpose of the utility model is to provide an assembled photovoltaic curtain wall structure that is convenient for later maintenance and replacement and has good stability.

[0007] In an embodiment of the utility model, an assembled photovoltaic curtain wall structure is provided, which includes: a plurality of connectors fixed on the structural beams of each floor of a multi-story building, a plurality of cross beams and a plurality of vertical beams respectively fixedly connected to the connectors.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] The implementation of the present utility model will be described in detail below in conjunction with specific embodiments.

[0023] As Figure 1 shown, in an embodiment of the present utility model, an assembled photovoltaic curtain wall structure is provided, which includes a plurality of connectors 1 fixed on the structural beams of each floor of a multi-story building, and a plurality of cross beams 2 and a plurality of vertical beams 3 respectively fixedly connected to the connectors 1. The plurality of cross beams 2 and the plurality of vertical beams 3 divide the building outer facade into a plurality of cells 4, and photovoltaic panels are arranged in the plurality of cells 4.

[0024] As Figure 2 shown, the connector 1 includes a connecting plate 11 and four upper, lower, left and right sleeves 12 fixed to the connecting plate 11. A screw hole 111 is provided on the connecting plate 11, and it is fixedly connected to the structural beam of the building through a reinforcing screw. The shapes of the two ends of the cross beam 2 and the vertical beam 3 are adapted to the shapes of the sleeves 12 of the connector 1. The two ends of the cross beam 2 are respectively fixedly connected to the left and right sleeves 12 of two adjacent connectors 1 in the horizontal direction, and the two ends of the vertical beam 3 are respectively connected to the upper and lower sleeves 12 of two adjacent connectors 1 in the vertical direction. Further, bolt holes 121 are provided on the sleeves 12 of the connector 1, corresponding bolt holes are provided at both ends of the cross beam 2 and the vertical beam 3, and both ends of the cross beam 2 and the vertical beam 3 are fixed to the sleeves 12 of the connector 1 through through bolts, so as to be firmly fixed to the building.

[0025] As Figure 3As shown, in the embodiment of the present utility model, the vertical beam 3 is a straight long strip, and the shape of the vertical beam 3 is in the shape of a "7", which includes an upper half 31 and a lower half 32 that are bent with each other. The extending directions of the upper and lower sleeves 12 of the connecting member 1 correspond to the extending directions of both ends of the vertical beam 3. The left and right sleeves 12 of the connecting member 1 are on a straight line and parallel to the ground. Of course, in other implementation manners, the vertical beam 3 can also be a straight long strip. At this time, the upper and lower sleeves 12 of the connecting member 1 are on a straight line and perpendicular to the ground.

[0026] Further as Figure 4 As shown, in the embodiment of the present utility model, since the upper half 31 of the vertical beam 3 is below the building structural beam and there is no local sight line and lighting requirement, therefore, a crystalline silicon photovoltaic panel 41 is provided on the upper half 31 of the vertical beam 3, so as to maximize the power generation efficiency. In some cells, a thin-film photovoltaic panel 42 is provided on the lower half 22 of the vertical beam 2 to ensure power generation while allowing light transmission. In addition, in some other cells 4, a glass window 43 is provided on the lower half 32 of the vertical beam 3 to meet the requirements of viewing, lighting and ventilation. The crystalline silicon photovoltaic panel 41, the thin-film photovoltaic panel 42 and the glass window 43 are all fixed by fixing members 33 provided on the cross beam 2 and the vertical beam 3. The ratio and specific setting positions of the thin-film photovoltaic panel 42 and the glass window 43 are determined according to actual needs, and the present utility model does not limit this.

[0027] Furthermore, as Figure 5 As shown, in the embodiment of the present utility model, the assembled photovoltaic curtain wall structure further includes a support grid 6 provided on the roof of the building, a plurality of crystalline silicon photovoltaic panels 61 provided on the support grid 6, and ventilation openings 62 provided between the plurality of crystalline silicon photovoltaic panels. By providing the ventilation openings 62 on the roof, the heat dissipation problem of the photovoltaic panels is solved, and the energy consumption and material loss are reduced.

[0028] In summary, for the prefabricated photovoltaic curtain wall structure of the present utility model, the entire curtain wall is connected by a connecting piece to the cross beam and the vertical beam, and is connected to the main structure of the building through the connecting plate and the strengthening screw of the connecting piece. Then, each photovoltaic panel is respectively installed on the cross beam and the vertical beam through fixing pieces, which can improve the accuracy of structure installation. At the same time, the connecting pieces can be mass-produced and are suitable for modular buildings, greatly improving the construction efficiency and reducing the production cost. The connecting pieces and the cross beam and vertical beam are combined to bear the force, increasing the wind resistance and seismic stiffness of the structure and effectively reducing the mutual influence between adjacent unit modules, enhancing the stability of the overall structure. Since the photovoltaic panels and the glass windows are on separate cross beams and vertical beams, they do not interfere with each other, and all are connected by bolts, making the installation, disassembly and later maintenance convenient and fast. By combining the characteristics of photovoltaic panels made of two different materials, crystalline silicon and thin film, and the overall building design, they are uniformly arranged on the facade and the roof to improve the power generation efficiency. At the same time, through different methods of opening window sashes and the open area on the roof, the heat dissipation problem of the photovoltaic panels is solved, reducing energy consumption and material loss.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
