Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a modular building with a steel-wood integrated photovoltaic roof. Background Technology

[0002] With the growing acceptance of sustainable development concepts, building-integrated photovoltaics (BIPV) technology has received widespread attention. However, traditional BIPV systems often rely on heavy materials such as metal or concrete, resulting in high installation costs and a lack of harmony with the natural environment. Furthermore, modular buildings are becoming increasingly popular in modern architecture due to their rapid construction, ease of transportation, and high flexibility. Therefore, we propose a modular steel-wood integrated photovoltaic roof to address these existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a modular building with a steel-wood integrated photovoltaic roof to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular building steel-wood photovoltaic integrated roof, comprising a roof assembly, wherein the roof assembly is provided from top to bottom with a photovoltaic panel, a first insulation layer, a self-adhesive flexible waterproof layer, an OSB board, a second insulation layer, pine sheathing and pine beams, and symmetrically arranged wooden beam fasteners on both sides of the pine beams, the pine beams being fixedly connected to crossbeams through the wooden beam fasteners, the pine beams having a trapezoidal structure, and the pine beams being fitted and connected to pine sheathing through the crossbeams.

[0005] Preferably, the photovoltaic panel, the first insulation layer, the self-adhesive flexible waterproof layer, the OSB board, the second insulation layer, the pine wood sheath, and the pine wood beam are bonded together with an adhesive.

[0006] Preferably, the first and second insulation layers are made of XPS material.

[0007] Preferably, a self-adhesive waterproof membrane is provided on one side of the pine beam, and both the self-adhesive waterproof membrane and the self-adhesive flexible waterproof layer are made of PVC material.

[0008] Preferably, a cement board protective layer is provided on the side of the pine beam near the self-adhesive waterproof membrane, and the pine beam is bolted to the main body of the house through the cement board protective layer.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The pine beams, with their trapezoidal structure, possess excellent load-bearing capacity and stability, providing primary support for the entire roof structure. Beam fasteners securely connect the pine beams to the crossbeams, forming a stable frame structure capable of withstanding the weight of the roof and potential external forces such as wind and snow loads. The pine beams are connected to pine sheathing boards via the crossbeams. These sheathing boards provide a flat base layer for the roof, supporting the various functional layers above, and together with the pine beams, form an integrated roof structure system, ensuring the structural strength and stability of the roof. A cement board protective layer is installed on the side of the pine beams closest to the self-adhesive waterproof membrane. This not only protects the membrane from external damage but also serves as a transition layer connecting the pine beams to the main building structure, allowing for better integration between the roof and the building. This transfers the load borne by the roof to the main building structure, ensuring the safety and stability of the entire building structure.

[0011] 2. As the top layer of the roof, photovoltaic panels utilize the photovoltaic effect to convert solar energy into electrical energy. When sunlight shines on the photovoltaic panels, the semiconductor materials inside absorb photon energy, causing electrons to transition and form an electric current, thereby realizing the power generation function and providing power support for the building to meet some or all of the building's internal electricity needs. The first and second insulation layers use XPS material. XPS material has an extremely low thermal conductivity, which can effectively prevent heat from being transferred through the roof. In the hot summer, it can block outdoor heat from entering the room, reducing the cooling load of indoor air conditioning. In the cold winter, it can prevent indoor heat from being lost to the outside, playing a good role in thermal insulation, maintaining a relatively stable indoor temperature, and reducing the building's energy consumption. The self-adhesive flexible waterproof layer and self-adhesive waterproof membrane use PVC material. PVC material has good weather resistance, water resistance, and flexibility. It can be tightly attached to the roof structure to form a continuous waterproof barrier, preventing rainwater, snow water, etc. from penetrating into the interior of the roof and protecting the structural layers below the roof and the interior space from water erosion.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figs. 1-2 As shown, this utility model proposes a modular building with a steel-wood integrated photovoltaic roof, including a roof assembly. The roof assembly is arranged from top to bottom as follows: photovoltaic panel 1, first insulation layer 2, self-adhesive flexible waterproof layer 3, OSB board 4, second insulation layer 5, pine wood sheath 6, and pine wood beam 7. Pine wood beam 7 is symmetrically provided with wooden beam fixing members 11 on both sides. The pine wood beam 7 is fixedly connected to the crossbeam 8 through the wooden beam fixing members 11. The pine wood beam 7 has a trapezoidal structure, and the pine wood sheath 6 is attached to the pine wood beam 7 through the crossbeam 8.

[0017] In an optional embodiment, the photovoltaic panel 1, the first insulation layer 2, the self-adhesive flexible waterproof layer 3, the OSB board 4, the second insulation layer 5, the pine wood sheath 6, and the pine wood beam 7 are bonded together with an adhesive.

[0018] In an optional embodiment, the first insulation layer 2 and the second insulation layer 5 are made of XPS material. The first insulation layer 2 and the second insulation layer are made of XPS material, which has an extremely low thermal conductivity and can effectively prevent heat from being transferred through the roof. In the hot summer, it can block outdoor heat from entering the room and reduce the cooling load of indoor air conditioning. In the cold winter, it can prevent indoor heat from being lost to the outside, thus playing a good role in thermal insulation, maintaining a relatively stable indoor temperature, and reducing the building's energy consumption.

[0019] In an optional embodiment, a self-adhesive waterproof membrane 9 is provided on one side of the pine beam 7, and both the self-adhesive waterproof membrane 9 and the self-adhesive flexible waterproof layer 3 are made of PVC material.

[0020] The self-adhesive flexible waterproof layer 3 and the self-adhesive waterproof membrane 9 are made of PVC material. PVC material has good weather resistance, water resistance and flexibility. It can be tightly attached to the roof structure to form a continuous waterproof barrier to prevent rainwater, snow water and other water from penetrating into the roof and protect the structural layers below the roof and the indoor space from water erosion.

[0021] In an optional embodiment, a cement board protective layer 10 is provided on the side of the pine beam 7 near the self-adhesive waterproof membrane 9, and the pine beam 7 is bolted to the main body of the house through the cement board protective layer 10.

[0022] The cement board protective layer 10 can protect the self-adhesive waterproof membrane 9 from damage by external factors. It can also serve as a transition layer connecting the pine beam 7 to the main structure of the house, allowing the roof to be better integrated with the main structure of the house, and transferring the load borne by the roof to the main structure of the house, thus ensuring the safety and stability of the entire building structure.

[0023] The working principle of this utility model is as follows: When using this device, the photovoltaic panel 1 serves as the top layer of the roof. The photovoltaic panel 1 utilizes the photovoltaic effect to convert solar energy into electrical energy. When sunlight shines on the photovoltaic panel 1, the semiconductor material within the photovoltaic panel 1 absorbs photon energy, causing electrons to transition and form an electric current, thereby achieving power generation and providing electrical support for the building, meeting some or all of the building's internal electricity needs. The first insulation layer 2 and the second insulation layer 5 are made of XPS material. XPS material has an extremely low thermal conductivity, effectively preventing heat transfer through the roof. In hot summers, it can block outdoor heat from entering the room, reducing the cooling load of indoor air conditioning. In cold winters, it can prevent indoor heat from escaping to the outside, providing good thermal insulation and maintaining a relatively stable indoor temperature, thus reducing building energy consumption. The self-adhesive flexible waterproof layer 3 and the self-adhesive waterproof membrane 9 are made of PVC material. The material has good weather resistance, water resistance and flexibility. It can be tightly attached to the roof structure to form a continuous waterproof barrier, preventing rainwater, snow water and other water from penetrating into the roof and protecting the structural layers below the roof and the interior space from water erosion.

[0024] The pine beam 7 has a trapezoidal structure, providing excellent load-bearing capacity and stability, and plays a major supporting role in the entire roof structure. The beam fasteners 11 firmly connect the pine beam 7 to the crossbeams 8, forming a stable frame structure capable of bearing the weight of the roof and external forces such as wind loads and snow loads. The pine beam 7 is connected to the pine sheath 6 through the crossbeams 8. The pine sheath 6 provides a flat base layer for the roof, supporting the various functional layers above, and together with the pine beam 7, it forms an integrated roof structure system, ensuring the structural strength and stability of the roof. The cement board protective layer 10 set on the side of the pine beam 7 near the self-adhesive waterproof membrane 9 not only protects the self-adhesive waterproof membrane 9 from damage by external factors, but also serves as a transition layer connecting the pine beam 7 to the main body of the house, allowing the roof to better integrate with the main body of the house, transferring the load borne by the roof to the main structure of the house, and ensuring the safety and stability of the entire building structure.

[0025] It should be understood that the specific embodiments described above are for illustrative purposes or to explain the principles of this utility model, and do not constitute a limitation thereof.
