[0027] A quick-installation structure for purlins includes a purlin 3 and two arc-shaped pieces 4;

[0028] The top surface of the purlin 3 is a plane and is used to fix it to the bottom surface of two adjacent frames 1 that surround the solar panel;

[0029] The purlin 3 is provided with an upwardly recessed snap-fit ​​mounting groove 31; the opening of the snap-fit ​​mounting groove 31 faces downward, and two snap-fit ​​holes 311 are provided on both sides of the groove wall of the snap-fit ​​mounting groove 31. The two snap-fit ​​holes 311 are arranged at intervals along the length of the snap-fit ​​mounting groove 31; the four snap-fit ​​holes 311 located on both sides of the groove wall of the snap-fit ​​mounting groove 31 are arranged in pairs and opposite to each other.

[0030] The upper end of the arc-shaped piece 4 is provided with a T-shaped buckle 41, and the lower end of the arc-shaped piece 4 is provided with a fastener mounting hole; the top of the T-shaped buckle 41 is provided with two insertion ends 411; the two insertion ends 411 are respectively mounted on the two opposite buckle holes 311; the lower ends of the two arc-shaped pieces 4 are connected by fasteners; the purlin 3 and the two arc-shaped pieces 4 form a clamp assembly and are clamped to the outer circumference of the main beam 2.

[0031] Figure 1 This is a schematic diagram of the installation structure of one embodiment of the quick installation structure for purlins according to this utility model. Figure 2 This is a schematic diagram of the installation structure of the clamp 5 of this utility model. Figure 3 This is a bottom view of the purlin 3 of this utility model.

[0032] like Figure 1-3As shown, during installation, the upper ends of the two arc-shaped pieces 4 are inserted into the buckle mounting grooves 31, and the two insertion ends 411 of the top of the T-shaped buckle 41 are positioned between the two opposite buckle holes 311. Then, the T-shaped buckle 41 is rotated 90° so that the extension direction of the top of the T-shaped buckle 41 is perpendicular to the length direction of the purlin 3, so that the two insertion ends 411 are respectively mounted in the two opposite buckle holes 311. The purlin 3 and the two arc-shaped pieces 4 form a clamp assembly. Then, the lower ends of the two arc-shaped pieces 4 are fixed with fasteners. The clamp assembly is tightened onto the outer circumference of the main beam 2. Then, two clamps are installed on the top surfaces of both ends of the purlin 3. Next, the two frames 1 of the solar panel assembly are inserted into the gaps between them and the purlin 3. Finally, the fixing bolts are tightened to complete the installation of one solar panel assembly. Then, the cables of each solar panel assembly can be passed through the corresponding frames to prevent them from scattering around the frames 1. Then, the cables are tied along the outer wall of the main beam 3 section by section. Finally, the cables are laid down along the column and connected to the corresponding electrical components.

[0033] Furthermore, the insertion end 411 is provided with a hook 4111;

[0034] The hook 4111 protrudes downward from the bottom edge of the insertion end 411, and the hook 4111 is exposed downward below the bottom edge of the buckle hole 311.

[0035] like Figure 1-3 As shown, a protrusion 4111 is provided at the bottom of the insertion end 411 of the T-shaped buckle 41, and the rotation of the T-shaped buckle 41 in the buckle hole 311 is restricted by the protrusion 4111, which can prevent the arc-shaped piece 4 from moving due to wind force during use and causing the T-shaped buckle 41 to loosen.

[0036] Furthermore, the purlin 3 is also provided with two limiting protrusions 312;

[0037] Two limiting protrusions 312 are spaced apart and distributed at both ends of the purlin 3. The limiting protrusions 312 protrude upward from the top surface of the purlin 3 and are used to be arranged between two adjacent frames 1.

[0038] like Figure 1 and Figure 2 As shown, two limiting protrusions 312 are set between the two frames 1, which can improve the positioning accuracy and operation convenience of the purlin 3 when it is installed on the two frames 1.

[0039] Furthermore, the purlin 3 is also provided with two spikes 313;

[0040] The two spikes 313 are located at the edge of the other end of the purlin 3 and protrude upward from the top surface of the purlin 3 respectively; the spikes 313 are used to pierce the oxide layer on the bottom surface of the frame 1.

[0041] like Figure 2 and Figure 4 As shown, by piercing the oxide layer on the bottom surface of the frame 1 with spike 4, the frame 1 can have better grounding performance through the main beam 2 and the column.

[0042] Furthermore, the purlin 3 is also provided with an arc-shaped portion 314;

[0043] The arc-shaped portion 314 is located at the edge of the slot of the snap-fit ​​mounting groove 31, the arc-shaped portion 314 is concave upward, and the arc-shaped portion 314 matches the outer peripheral surface of the main beam 2.

[0044] like Figure 1-2 As shown, the arc-shaped portion 314 can improve the matching degree between the bottom surface of the purlin 3 and the outer peripheral surface of the main beam 2, thereby improving the installation stability of the purlin 3 on the outer peripheral surface of the main beam 2.

[0045] In summary, such as Figure 1-4 The embodiment of the present invention shown in the figure has a quick-installation structure for the purlin, in which the purlin 3 and the two arc-shaped pieces 4 form a snap-fit ​​connection clamp assembly, and the connection and fixation between the purlin 3 and the two arc-shaped pieces 4 only uses one fastener, which can effectively improve the installation efficiency.

[0046] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
