Description

Technical Field

[0001] This utility model relates to the field of green building technology, specifically a green building roof structure. Background Technology

[0002] With the acceleration of urbanization and the increase in building density, the unused space on traditional building rooftops has not been fully utilized, leading to resource waste and exacerbating the urban heat island effect. At the same time, the construction industry's demand for energy conservation, emission reduction, and green ecology is becoming increasingly urgent. Against this backdrop, green building roof technology, as an important means of achieving sustainable building development, has gradually received widespread attention.

[0003] Traditional green roofs are mostly constructed by integral casting or on-site masonry, which has a long construction period and high cost, making it difficult to adapt to the renovation of existing buildings. Moreover, traditional roof greening systems often only focus on a single function (such as planting or power generation), failing to achieve the multi-functional use of space and failing to fully realize the ecological and economic value of the roof.

[0004] To address the aforementioned issues, there is an urgent need to develop a modular, easy-to-install, and multifunctional green building roof structure to achieve the dual goals of efficient utilization of roof space and building energy conservation. Utility Model Content

The supporting part includes a base, a number of partitions equal to the number of planting areas, and positioning plates twice the number of partitions. The base is connected and fixed to the roof surface by fasteners. Multiple partitions are evenly spaced on the top of the base and extend outward from the center of the base. Each partition has two positioning plates. Multiple planting areas and water storage areas are placed in the gaps between the partitions, and adjacent planting areas and water storage areas are separated by positioning plates, so that multiple planting areas and multiple water storage areas are arranged in a ring on the base. The water storage areas are used to collect rainwater and channel it into the planting areas, and the planting areas are used to plant greenery.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 A green building roof structure may include a roof surface 10, a support 20, multiple photovoltaic panels 30, and multiple planting areas 40 and water storage areas 50. The roof surface 10 may be an existing flat roof, allowing the support 20 to be secured to the roof surface 10 using fasteners such as expansion bolts. The multiple photovoltaic panels 30 and the multiple planting areas 40 and water storage areas 50 are all mounted on the support 20.

[0024] See Figure 2The support unit 20 includes a base 21, a number of partition frames 22 equal to the number of planting areas 40, and a number of positioning plates 23 twice the number of partition frames 22. The base 21 is disc-shaped and is fixed to the roof surface 10 by fasteners. Multiple partition frames 22 are formed at equal intervals on the top of the base 21 and extend outward from the center of the base 21. Each base 21 has two positioning plates 23 formed at intervals. The partition frames 22 and positioning plates 23 are used to separate and position the installation of the photovoltaic panels 30, planting areas 40, and water storage areas 50.

[0025] See Figure 3 The planting area 40 includes a first base 41, a cover plate 42, multiple water-absorbing strips 43, and planting soil 44. A first support ring 411 is formed on the bottom section of the inner wall of the first base 41. The cover plate 42 rests on the first support ring 411 and covers its lower cavity for water storage. Multiple water-absorbing strips 43 are inserted into the cover plate 42, with the lower end of the strips extending into the bottom of the first base 41 and the upper end inserted into the planting soil 44, allowing the planting soil 44 to absorb water stored at the bottom of the first base 41 using the water-absorbing strips 43. The water-absorbing strips contain numerous tiny pores, through which water molecules rise, similar to the principle of "plant vascular transport of water." When the soil dries, the soil water potential decreases, and the water in the contact area between the water-absorbing strips and the soil is "pulled" towards the soil, forming a continuous water flow. The absorbent strip can consist of an inner layer and an outer layer. The inner layer is made of cotton thread, acrylic fiber, polyester fiber, or wood pulp fiber, which can absorb and transfer water. The outer layer can be made of polypropylene mesh, non-woven fabric, or a sponge layer and is wrapped around the inner layer to protect it and prevent excessive evaporation and clogging. Planting soil 44 is filled in the inner cavity of the first base 41 located above the cover plate 42 and is used for planting greenery.

[0026] See Figure 3 The water storage area 50 includes a second base 51, a filter plate 52, and at least one inner ring connecting pipe 53. A second support ring 511 is formed on the top section of the inner wall of the second base 51. The filter plate 52 has multiple openings penetrating the filter plate 52 and rests on the second support ring 511. Rainwater can flow into the second base 51 through the openings, and the openings in the filter plate 52 reduce the entry of garbage and larger particles. One end of the inner ring connecting pipe 53 is connected to the bottom of the second base 51, and the other end of the inner ring connecting pipe 53 is inserted into and connected to the bottom of the adjacent first base 41, so that the water storage area 50 can replenish water to the planting area 40.

[0027] In this embodiment, multiple photovoltaic panels 30 are also arranged in a ring array between multiple partition frames 22, and the photovoltaic panels 30 and the planting area 40 are also separated by positioning pieces 23. The photovoltaic panels 30 can be supported and fixed on the base 21 by brackets, and the photovoltaic panels 30 can be used to provide auxiliary power to the building.

[0028] In this embodiment, to improve the indoor brightness of the building, an opening penetrating the roof surface 10 can be formed. An extended lighting unit 24 can then be fixedly installed at the center of the base 21, positioned inside the multiple partition frames 22. The bottom of the extended lighting unit 24 penetrates the base 21 and faces the opening on the roof surface 10. The extended lighting unit 24 can be made of explosion-proof glass in a cylindrical shape, allowing sunlight to pass through and enter the building, thereby improving the indoor brightness. Additionally, the internal cavity of the extended lighting unit 24 can be vented, making its interior nearly a vacuum, thereby improving its heat insulation capacity and reducing the impact of the external environment on the indoor temperature through the extended lighting unit 24.

[0029] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
