[0035] Figure 1 A main structural diagram of a courtyard-type photovoltaic truss structure according to an embodiment of the present application is shown; Figure 2 The embodiment of the present application is shown Figure 1 A partial enlarged view of Figure 3 FIG. 2 shows a front view of a truss according to an embodiment of the present application. Figure 1 , Figure 2 and Figure 3As shown, the courtyard-type photovoltaic truss structure comprises: more than two trusses 100; more than two trusses 100 are arranged in sequence and arranged opposite to each other, and each adjacent two trusses 100 are connected by two inter-chord connection components 200; the truss 100 comprises: an upper chord rod 150, a lower chord rod 160, and a first column 110 and a second column 120 arranged parallel to each other; the upper chord rod 150 is erected on the top of the first column 110 and the second column 120, and the two ends of the upper chord rod 150 protrude from the first column 110 and the second column 120 respectively; the lower chord rod 160 is arranged between the first column 110 and the second column 120, and the body length direction of the lower chord rod 160 is perpendicular to the body length direction of the first column 110; there are more than two chord rods 150 and 160 between the upper chord rod 150 and the lower chord rod 160. A first reinforcement beam 170; the inter-chord connection assembly 200 includes: an upper chord horizontal tie rod 210 and a lower chord horizontal tie rod 220 arranged in parallel with each other; the upper chord horizontal tie rod 210 is vertically connected to the upper chord rods 150 of two adjacent trusses 100, and the lower chord horizontal tie rod 220 is vertically connected to the lower chord rods 160 of two adjacent trusses 100; a first cross support beam 400 is provided between two adjacent trusses 100 at both ends; and the first cross support beam 400 is provided between the two inter-chord connection assemblies 200 of the two trusses 100; the two inter-chord connection assemblies 200 between the two adjacent trusses 100 at both ends are each provided with more than two in-chord support beams 230, and the more than two in-chord support beams 230 are arranged between the upper chord horizontal tie rod 210 and the lower chord horizontal tie rod 220.

[0036] Here, it should be noted that more than two trusses 100 are suitable for supporting the photovoltaic panels 800, and the two inter-chord connection components 200 are suitable for connecting all the trusses 100 as a whole. When the overall structure is built, under the fixing and limiting effect of the two inter-chord connection components 200, it can be ensured that each truss 100 after construction is parallel to each other, and it is also ensured that when the photovoltaic panel 800 is finally installed, each truss 100 always maintains a relatively balanced state, and will not be unable to install or unstable due to inaccurate positions between the two trusses 100. Furthermore, the upper chord rod 150 is used to bear the photovoltaic panel 800 load, wind load, snow load, and constant load transmitted from the purlin 700. The upper chord rod 150 transmits force to the lower chord rod 160 through more than two first reinforcement beams 170. Both ends of each upper chord horizontal tie rod 210 are connected to the upper chord rod 150. Under the action of all the upper chord horizontal tie rods 210, the force exerted on the upper chord rods 150 of all the trusses 100 can be evenly distributed. Both ends of each lower chord horizontal tie rod 220 are connected to the lower chord rod 160. Under the action of all the lower chord horizontal tie rods 220, the force exerted on the lower chord rods 160 of all the trusses 100 can be evenly distributed. Therefore, the setting of the inter-chord connection assembly 200 can also prevent the truss 100 from being subjected to single-point force and causing the truss 100 to collapse. The two inter-chord connection assemblies 200 between the two adjacent trusses 100 at the two ends are provided with more than two in-chord support beams 230; the more than two in-chord support beams 230 are suitable for further supporting the upper chord horizontal tie rod 210 and the lower chord horizontal tie rod 220, and the first cross support beam 400 between the two adjacent trusses 100 at the two ends is suitable for improving the support strength of the trusses 100 at the two ends to avoid the upper chord horizontal tie rod 210 and the lower chord horizontal tie rod 220 being broken due to the large pressure, resulting in the position change between the two adjacent trusses 100 at the two ends. The present application has strong support stiffness, optimizes the utilization efficiency of materials, ensures structural safety, and meets the special use requirements of courtyard-type photovoltaic sunrooms. Through reasonable design and optimization, higher economic and social benefits can be achieved.

[0037] In a possible implementation, it further includes: more than two purlins 700; more than two purlins 700 are arranged adjacently on the top surface of the upper chord 150 of all trusses 100, and the length direction of the purlin 700 is perpendicular to the length direction of the upper chord 150. Here, it should be noted that, if Figure 2As shown, the top surface of the purlin 700 is suitable for contacting the photovoltaic panel 800, and the photovoltaic panel 800 is directly fixed on the purlin 700; each upper chord 150 below the purlin 700 is suitable for receiving the pressure exerted on the purlin 700. Furthermore, two purlins 700 are provided below each photovoltaic panel 800. With the two purlins 700 supporting the photovoltaic panel 800 at the same time, it can be ensured that the photovoltaic panel 800 will not rotate or displace, and the installation stability of the photovoltaic panel 800 is effectively ensured. Here, it should be noted that the number of purlins 700 is not limited in this application, and the specific number of purlins 700 can be determined according to the number of photovoltaic panel assemblies.

[0038] In one possible implementation, there are 12 purlins 700 , which are horizontally placed above the upper chords 150 of all trusses 100 , and the length directions of the 12 purlins 700 are parallel to the upper chord horizontal tie rods 210 and the lower chord horizontal tie rods 220 .

[0039] In a possible implementation, the upper chord 150 is provided with a folded angle a, and the protruding direction of the folded angle a is away from the lower chord 160. Figure 3 As shown, the angle a is located in the middle of the upper chord 150, and the angle value of the angle a is consistent with the inclination angle required by the photovoltaic panel assembly. The upper chord 150 is buckled at the top of the first column 110 and the second column 120. The overall length of the upper chord 150 is greater than the overall length of the lower chord 160. The two ends of the upper chord 150 protrude outward. Lengthening the length of the upper chord 150 can ensure that the first column 110 and the second column 120 will not tilt outward due to the large force on the top. The main body of the lower chord 160 is a horizontal long rod structure, and the two ends of the lower chord 160 are respectively connected to the first column 110 and the second column 120.

[0040] In a possible implementation, two or more first reinforcement beams 170 are provided between the upper chord 150 and the lower chord 160. Figure 3 As shown, more than two first reinforcement beams 170 form a plurality of "N"-shaped structures arranged in sequence. Under the support of the first reinforcement beams 170, the connection between the upper chord 150 and the lower chord 160 can be ensured to be stable, and the force exerted on the upper chord 150 can be evenly distributed to the lower chord 160.

[0041] In a possible implementation, the truss 100 further includes: two second reinforcement beams 130; two ends of one of the second reinforcement beams 130 are respectively connected to the lower chord 160 and the first column 110; two ends of the other second reinforcement beam 130 are respectively connected to the lower chord 160 and the second column 120. Here, it should be noted that the second reinforcement beam 130 is suitable for supporting and reinforcing the lower chord 160, improving the stability of the lower chord 160 on the first column 110 and the second column 120, and further improving the structural strength of the truss 100. Further, as Figure 3 As shown, a preset angle b is set between the length direction of one second reinforcement beam 130 and the length direction of the first column 120, and a preset angle b is also set between the length direction of the other second reinforcement beam 130 and the length direction of the second column 120, and both preset angles b are 45°.

[0042] In a possible implementation, the truss 100 further includes: two third reinforcement beams 140; two ends of one of the third reinforcement beams 140 are respectively connected to the upper chord 150 and the first column 110; two ends of the other third reinforcement beam 140 are respectively connected to the upper chord 150 and the second column 120. Here, it should be noted that the third reinforcement beam 140 is suitable for supporting and reinforcing the protruding portion of the upper chord 150, improving the stability of the upper chord 150 at the top of the first column 110 and the second column 120, avoiding the protruding portion of the upper chord 150 from being broken due to the large force, and further improving the overall structural strength of the truss 100.

[0043] In one possible implementation, Figure 3 As shown, the intersection point where the second reinforcement beam 130 is connected to the first column 110 and the intersection point where the third reinforcement beam 140 is connected to the first column 110 are the same point. The intersection point where the third reinforcement beam 140 is connected to the second column 120 and the intersection point where the third reinforcement beam 140 is connected to the second column 120 are also the same point. A preset angle c is set between the length direction of one of the third reinforcement beams 140 and the length direction of the first column 120, and a preset angle c is also set between the length direction of the other third reinforcement beam 140 and the length direction of the second column 120, and both preset angles c are 30°.

[0044] In a possible implementation, it also includes: two inter-column connection components 300; Figure 2As shown, the first columns 110 of more than two trusses 100 are connected by one of the inter-column connection assemblies 300; the second columns 120 of more than two trusses 100 are connected by another inter-column connection assembly 300. Here, it should be noted that, in order to further ensure the position stability between all trusses 100 and avoid displacement, deflection or overall tipping of the trusses 100 due to large force, one of the inter-column connection assemblies 300 connects the first columns 110 of all trusses 100 as a whole, and the other inter-column connection assembly 300 connects the second columns 120 of all trusses 100 as a whole, so as to firmly connect each truss 100.

[0045] In a possible implementation, the inter-column connection assembly 300 includes: a first inter-column support rod 310 and a second inter-column support rod 330 arranged in parallel with each other; the first inter-column support rod 310 connects the connection intersection of each first column 110 and the lower chord 160. Figure 2 As shown, the main body of the first inter-column support rod 310 is a long bar-shaped structure, and the first inter-column support rod 310 sequentially connects the connection points of the first column 110 of each truss 100 and the lower chord 160 of each truss 100; the second inter-column support rod 330 sequentially connects the connection intersections of each first column 110 and the third reinforcement beam 140. The first inter-column support rod 310 of another inter-column connection assembly 300 sequentially connects the connection points of the second column 120 of each truss 100 and the lower chord 160 of each truss 100; the second inter-column support rod 330 of another inter-column connection assembly 300 sequentially connects the connection points of the second column 120 of each truss 100 and the third reinforcement beam 140 of each truss 100.

[0046] In a possible implementation, two or more fourth reinforcement beams 320 are provided between the first inter-column support rod 310 and the second inter-column support rod 330. Figure 2 As shown, more than two fourth reinforcement beams 320 are arranged into a plurality of "W"-shaped structures and connected in sequence. Under the action of the fourth reinforcement beams 320, the first inter-column support rod 310 and the second inter-column support rod 330 are reinforced, and the first inter-column support rod 310 can evenly distribute the force to the second inter-column support rod 330.

[0047] In one possible implementation, Figure 2As shown, two inter-chord connection assemblies 200 are provided between each two adjacent trusses 100, and the two inter-chord connection assemblies 200 are arranged parallel to each other, and the two inter-chord connection assemblies 200 between each two adjacent trusses 100 are symmetrically arranged along the central axis of the lower chord 160. One of the inter-chord connection assemblies 200 between each two adjacent trusses 100 is located in the same plane as one of the inter-chord connection assemblies 200 between the other two adjacent trusses 100; another inter-chord connection assembly 200 between each two adjacent trusses 100 is located in the same plane as another inter-chord connection assembly 200 between the other two adjacent trusses 100; thereby, multiple photovoltaic panels 800 are supported more evenly. It should be noted that the present application does not limit the number of trusses 100, and the number of trusses 100 is determined according to the number of photovoltaic panel assemblies.

[0048] In one possible implementation, the trusses 100 are provided with eight in total, such as Figure 1 As shown, the structure of each truss 100 is the same, each truss 100 is arranged parallel to each other and corresponding to each other, and the distances between the eight trusses 100 are the same. There are fourteen inter-chord connection components 200 between the eight trusses 100, of which seven inter-chord connection components 200 are located in the same plane, and the seven upper chord horizontal tie rods 210 of the seven inter-chord connection components 200 are located in the same straight line, and the seven lower chord horizontal tie rods 220 are located in the same straight line; another seven inter-chord connection components 200 are located in the same plane, and the seven upper chord horizontal tie rods 210 of the seven inter-chord connection components 200 are located in the same straight line, and the seven lower chord horizontal tie rods 220 are located in the same straight line.

[0049] The eight trusses 100 are arranged from left to right in sequence as a first truss 100 , a second truss 100 , a third truss 100 , ... a seventh truss 100 and an eighth truss 100 ; this is to provide a clearer description.

As the support point of the upper chord horizontal tie rod 210 and as the key load-bearing component of the present application, the in-chord support beam 230 can effectively transfer force to the first cross support beam 400.

[0051] In a possible implementation, a first cross support beam 400 is provided between two adjacent trusses 100 at both ends; and the first cross support beam 400 is provided between two inter-chord connection components 200. Figure 2 As shown, the main body of the first cross support beam 400 is an "X"-shaped structure, and the four corners of the "X"-shaped structure are respectively connected at: the connection intersection of one of the lower chord horizontal tie rods 220 and the lower chord rod 160 of the first truss 100, the connection intersection of one of the lower chord horizontal tie rods 220 and the lower chord rod 160 of the second truss 100, the connection intersection of another lower chord horizontal tie rod 220 and the lower chord rod 160 of the first truss 100, and the connection intersection of another lower chord horizontal tie rod 220 and the lower chord rod 160 of the second truss 100.

[0054] As above, the second cross-support beam 500 and the third cross-support beam 600 between the seventh truss 100 and the eighth truss 100 are also connected in the same way.

[0055] The force transmission path of the whole system is as follows: the purlin 700 transmits the pressure received to the upper chord rod 150 of each truss 100; the upper chord rod 150 of each truss 100 transmits the force to the upper chord horizontal tie rod 210 and the lower chord rod 160, the lower chord rod 160 transmits the force to the lower chord horizontal tie rod 220, and then the upper chord horizontal tie rod 210 and the lower chord horizontal tie rod 220 transmit the force to the inner chord support beam 230 of the two adjacent trusses 100 at both ends, and finally the inner chord support beam 230 transmits the force to the three cross support beams. This force transmission path design optimizes the stress state of the structure and improves the support stiffness.
