[0002] Currently, during the construction of a distributed household photovoltaic greenhouse, the roof beams are usually connected by welding.

[0003] Since the welding method will damage the zinc-aluminum-magnesium coating on the surface of the roof beam (for example, welding white spots (a weld defect manifested as white residues) are likely to appear at the welded joints of the roof beam), the strength value and anti-corrosion effect of the roof beam are damaged, thereby impairing the service life of the roof beam. Utility Model Content

[0004] In view of this, the embodiments of the present application provide a connection component and a roof beam component, which can avoid damaging the strength value and anti-corrosion effect of the roof beam and ensure the service life of the roof beam.

[0005] The connection component of the present application includes: a first connecting piece for connecting the secondary beam of the roof beam, the first connecting piece is provided with a fixing groove, the fixing groove matches the shape of the secondary beam of the roof beam, and the secondary beam is arranged in the fixing groove; a second connecting piece for connecting the main beam of the roof beam, the second connecting piece includes an opening, the shape of the opening matches the shape of the main beam of the roof beam, and the main beam is arranged in the opening; the first connecting piece and the second connecting piece are fixedly connected to connect the main beam and the secondary beam.

[0006] In some embodiments, the fixing groove is U-shaped and is arranged to match the secondary beam of the roof beam.

[0007] In some embodiments, the first connecting piece includes a fixing part and two first connecting parts, the fixing part is provided with the fixing groove, and the two first connecting parts are respectively arranged on both sides of the fixing groove.

[0008] In some embodiments, at least one of the two first connecting parts is provided with an installation hole, and the second connecting piece passes through the installation hole to be fixedly connected to the first connecting piece.

[0009] In some embodiments, the second connecting piece includes a screwing part, the screwing part passes through the installation hole, and the connection component further includes a fixing nut, and the fixing nut is screwed with the screwing part to fixedly connect the first connecting piece and the second connecting piece.

[0010] In some embodiments, the shape of the opening matches the cross-section of the main beam of the roof beam, and the shape of the opening is rectangular.

[0011] In some embodiments, there are two second connectors, which correspond to the first connection parts one by one, and the second connectors penetrate and connect the corresponding first connection parts.

[0012] In some embodiments, the second connector includes a body and two second connection parts. The two second connection parts are respectively connected to two ends of the body. The body and the two second connection parts enclose the opening, and the two second connection parts penetrate and connect the corresponding first connection parts.

[0013] In some embodiments, the first connector is integrally formed.

[0014] The beam assembly according to the embodiment of the present application includes a main beam, a secondary beam, and the connection assembly described in any of the above embodiments.

[0015] For the connection assembly and the beam assembly according to the embodiment of the present application, the secondary beam of the beam is connected by the first connector. Since the shape of the fixing groove formed in the first connector matches the shape of the secondary beam of the beam, and the secondary beam is arranged in the fixing groove, it can ensure the tightness of the connection between the first connector and the secondary beam of the beam, and can also reduce the positioning requirement between the first connector and the secondary beam during installation; the main beam of the beam is connected by the second connector. Since the shape of the opening of the second connector matches the shape of the main beam of the beam, and the main beam is arranged in the opening, it can improve the stability when the second connector connects the main beam of the beam, and can also reduce the positioning requirement between the second connector and the main beam during installation; finally, through the fixed connection between the first connector and the second connector (for example, fixed connection by screwing, gluing, etc.), the fixed connection between the main beam and the secondary beam is realized, effectively preventing the relative movement between the main beam and the secondary beam of the beam. The structure is simple and the operation is convenient. It can not only avoid affecting the service life of the main beam and the secondary beam and reduce the maintenance work, but also ensure the installation efficiency.

[0027] In recent years, the application of solar photovoltaic buildings has become more and more extensive, that is, by combining a photovoltaic power generation system with a building. For example, photovoltaic devices (such as photovoltaic panels) are arranged on the peripheral structural surface of the building, and the photovoltaic devices absorb solar energy and convert the solar energy into electric energy to generate green energy for users.

[0028] At present, there are usually two ways to combine photovoltaic power generation systems with buildings. One is the "installation type" solar photovoltaic building (Building Attached Photovoltaic, BAPV), which refers to a solar photovoltaic power generation system attached to a building. Generally, photovoltaic devices are covered on the roof of the building to form a photovoltaic power generation system. The other is building integrated photovoltaics (BIPV), which means integrating a solar photovoltaic system into the building. Generally, building materials and photovoltaic devices are integrated, and the photovoltaic devices directly replace building materials. For example, integrating solar photovoltaic cells with building materials such as glass curtain walls, window glasses, or roof tiles to build a building with building integrated photovoltaics. This building can generate electricity through solar energy, reduce dependence on traditional electricity, lower energy consumption, and save energy costs; by directly integrating the photovoltaic system into the building, there is no need to occupy additional ground or roof space, saving the space for additional installation of photovoltaic panels and achieving the maximum utilization of space; it can not only develop and apply green energy but also integrate with the building to achieve the effect of energy conservation and environmental protection.

[0029] The distributed household photovoltaic sunroom is a specific implementation of BIPV. In current distributed household photovoltaic sunrooms, the roof beams are mostly made of low-alloy high-strength steel (for example, galvanized aluminum-magnesium steel plates of model S350GD-ZM are generally used). During the construction of the distributed household photovoltaic sunroom, the roof beams are usually connected by welding.

[0030] Since the welding method requires hot work, high temperature and sparks are involved during welding (usually flames or arcs are used to heat and melt metals), and hot work poses significant safety hazards (sparks may trigger fires in surrounding flammable items, the high temperature generated may cause burns or thermal injuries, and gas leakage or poor ventilation during welding can easily lead to poisoning risks); in the case of substandard welding quality (i.e., insecure welding), there are also significant safety hazards (for example, when the welded joint is insecure, the strength and stability of the welded structure will be affected, which may cause the welded structure to break or fail when bearing loads, thus triggering danger); furthermore, since the high temperature generated during welding can melt or burn the zinc-aluminum-magnesium coating, exposing the base material of the roof beam to the environment and increasing the corrosion risk. In other words, the welding method will damage the zinc-aluminum-magnesium coating on the surface of the roof beam (for example, welding white spots (a weld defect manifested as white residues) are likely to appear at the welded joints of the roof beam), thereby damaging the strength value and anti-corrosion effect of the roof beam. Moreover, during the welding process, the high temperature generated by welding may have changed the material structure of the welded part, affecting the adhesion and adhesion effect of the anti-corrosion zinc-aluminum-magnesium coating. In addition, the slag and gas during the welding process may contaminate the coating surface, affecting the adhesion and uniformity of the zinc-aluminum-magnesium coating. Therefore, even after anti-corrosion treatment of the welded part, it is still very difficult to achieve the original anti-corrosion effect, resulting in corrosion of the base material, making subsequent maintenance more complex and expensive, damaging the service life of the roof beam, and causing the photovoltaic building to fail to meet the service life requirement of 25 years.

[0031] The connection component 100 provided by the present application will be elaborated in detail below.

[0032] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a connection component 100. The connection component 100 can be used for the roof beam component 1000. The roof beam component 1000 includes the connection component 100, the secondary beam 200, and the main beam 300, which will be introduced in detail below:

[0033] The connection component 100 includes a first connection member 10 and a second connection member 20;

[0034] The first connection member 10 is used to connect the secondary beam 200 of the roof beam. The first connection member 10 is provided with a fixing groove 11, and the fixing groove 11 matches the shape of the secondary beam 200 of the roof beam. The secondary beam 200 is arranged in the fixing groove 11;

[0035] The second connection member 20 is used to connect the main beam 300 of the roof beam. The second connection member 20 includes an opening, and the shape of the opening matches the shape of the main beam 300 of the roof beam. The main beam 300 is arranged in the opening;

[0036] The first connecting member 10 and the second connecting member 20 are fixedly connected to connect the main beam 300 and the secondary beam 200.

[0037] Among them, the fixing groove 11 is U-shaped, and the fixing groove 11 is arranged to match the secondary beam 200 of the roof beam.

[0038] Among them, the shape of the opening matches the cross-section S1 of the main beam 300 of the roof beam, and the shape of the opening is rectangular.

[0039] Specifically, the secondary beam 200 of the roof beam is connected by the first connecting member 10. The fixing groove 11 opened in the first connecting member 10 matches the shape of the secondary beam 200 of the roof beam. The secondary beam 200 is arranged in the fixing groove 11 so that the first connecting member 10 and the secondary beam 200 of the roof beam can be engaged. Since the fixing groove 11 is U-shaped, it can be sleeved on the secondary beam 200 of the roof beam to increase the contact surface between the first connecting member 10 and the secondary beam 200 of the roof beam, thereby improving the connection stability, and can also reduce the positioning requirement between the first connecting member 10 and the secondary beam 200 during installation; the second connecting member 20 is connected to the main beam 300 of the roof beam. The shape of the opening of the second connecting member 20 matches the shape of the main beam 300 of the roof beam. The main beam 300 is arranged in the opening so that the second connecting member 20 and the main beam 300 of the roof beam can be engaged. Please refer to Figure 2 , the shape of the opening is rectangular and matches the cross-section of the main beam 300 of the roof beam. It can be sleeved on the main beam 300 of the roof beam and engaged with the main beam 300 to improve the connection stability, and can also reduce the positioning requirement between the second connecting member 20 and the main beam 300 during installation; finally, through the fixed connection between the first connecting member 10 and the second connecting member 20, for example, by screwing, gluing and other methods of fixed connection, the fixed connection between the main beam 300 and the secondary beam 200 is realized. The structure is simple and the operation is convenient. It can not only avoid affecting the service life of the main beam 300 and the secondary beam 200, but also ensure the installation efficiency.

[0040] Compared with the current connection method between the main beam 300 and the secondary beam 200 by welding, the connection assembly 100 of the present application can avoid the hot work of welding and the potential safety hazards caused by unqualified welding quality (i.e., insecure welding); it can also avoid damaging the strength value and anti-corrosion effect of the roof beam and ensure the service life of the roof beam.
