Description

Technical Field

[0001] This invention relates to the field of structural components, and more specifically to a purlin assembly and installation process for quick installation on photovoltaic roofs. Background Technology

[0002] As attached Figure 1 As shown, the photovoltaic module 400 and the corrugated steel roof 300 are typically connected by purlins, with the traditional purlin being a purlin 200 with folded edges. The connection between the purlin 200 and the corrugated steel roof requires temporary drilling based on site conditions, as it's impossible to pre-drill holes 201 (hole positions 201 are generally drilled in a row). This makes on-site construction inconvenient and inefficient. Furthermore, the folded edges of the purlins are mostly pre-installed to fit the site, resulting in significant material waste and increased costs.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0004] The present invention aims to solve the aforementioned technical problems of traditional purlins with folded edges by providing a purlin assembly and installation process for quick installation on photovoltaic roofs. The support is installed on the purlin slide rail through a semi-hanging pivot unit and an inverted buckle unit, and quick assembly can be completed by simply pressing without tools. After the support is fixed to the purlin slide rail, there are limit positions in the upper, lower and left and right directions, which will not cause it to disengage and ensure connection stability.

[0005] The present invention is implemented as follows: a purlin assembly for quick installation on photovoltaic roofs, comprising a purlin slide rail for installation with photovoltaic modules and a support for installation on corrugated steel roofs, wherein the purlin slide rail and the support are separately provided and are assembled by a semi-hanging pivot unit and an inverted snap unit.

[0006] Furthermore, the purlin slide rail includes a main body with a U-shaped cross-section; the support includes a base plate; the semi-hanging pivot unit includes a first hook and a second hook that cooperate, the first hook being integrally formed on one side of the main body, and the second hook extending to form on the upper surface of the middle part of the base plate; the buckle unit includes a buckle bevel and a Z-shaped buckle plate that cooperate, the buckle bevel being integrally formed on the other side of the main body, and the Z-shaped buckle plate being integrally formed on the upper surface of the middle part of the base plate, the Z-shaped buckle plate forming a buckle step that cooperates with the buckle bevel.

[0007] Furthermore, the second hook and the Z-shaped buckle plate form a receiving cavity for accommodating the main body, and the upper surface of the support plate is recessed with a relief groove that communicates with the receiving cavity.

[0008] Furthermore, the base plate has a first extension plate and a second extension plate extending from both sides, with a first punch hole on the first extension plate and a second punch hole on the second extension plate.

[0009] On the other hand, the installation process of the purlin assembly for quick installation on photovoltaic roofs includes the following steps: S1: Align the second hook with the first hook, so that the support and the purlin slide rail are connected for the first time by the semi-hanging pivot unit; S2: The support rotates around the semi-hanging pivot unit, and the Z-shaped buckle end on the right side of the support slides upward along the slope of the inverted buckle angle, and finally the inverted step buckles onto the upper surface of the inverted buckle angle, so that the support and the purlin slide rail are assembled for the second time by the inverted buckle unit; S3: As needed, the support slides along the purlin slide rail for fine adjustment to adapt to different spacing installations; the support is locked to the color steel tile roof by bolt assembly at the first punch and the second punch.

[0010] On the other hand, the installation process of the purlin assembly for quick installation on photovoltaic roofs includes the following steps: S1: First, fix two supports to the corrugated steel sheet crests with bolt assemblies; align the first hook with the second hook, so that the support and purlin slide rail are connected by the first hook through the semi-hanging pivot unit; S2: The purlin slide rail rotates around the semi-hanging pivot unit, the inclined surface of the inverted angle presses against the inverted end of the Z-shaped buckle plate, and finally the Z-shaped buckle plate is fastened on the inverted step, so that the support and purlin slide rail are assembled by the inverted buckle unit for the second time.

[0011] The purlin assembly of the present invention has the following beneficial technical effects:

[0012] 1. The support is installed on the purlin slide rail through a semi-hanging shaft unit and an inverted buckle unit. It can be quickly assembled by simply pressing without tools, reducing the difficulty of manual operation. After the support is fixed to the purlin slide rail, there are limit positions in the up, down, left and right directions, which will not disengage and ensure the stability of the connection.

[0013] 2. The purlin slide rail and support are designed separately. The front support can be inserted and slid along the purlin slide rail for fine adjustment. The installation distance can be adjusted as needed on the construction site.

[0014] 3. The punching holes of the support can be prefabricated, avoiding on-site drilling and improving production efficiency and on-site installation efficiency.

[0015] 4. The purlins have eliminated the traditional folded edges, resulting in a smaller overall volume, reduced material waste, lower aluminum usage, and lower costs.

[0016] The installation process of the purlin assembly of this invention is extremely simplified, completed in three steps: hooking, rotating, and fastening. It is quick and easy for a single person to operate. The support slides along the purlin rail to adapt to different spacings and locks in place, which improves the fault tolerance rate. Moreover, no drilling is required for on-site installation, which greatly improves the installation efficiency. Attached Figure Description

Detailed Implementation

[0029] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1 to 8As shown, this invention provides a purlin assembly 100 for quick installation on photovoltaic roofs, including a purlin slide rail 1 for installation with a photovoltaic module 400 and a support 2 for installation with a corrugated steel roof 300. The purlin slide rail 1 and the support 2 are separately arranged and assembled by a semi-hanging pivot unit and an inverted fastening unit. The purlin slide rail 1 and the support 2 are interference fit, resulting in high vertical friction after assembly, making it difficult to slide after fastening. Fine adjustments can be made before fastening. The semi-hanging pivot unit facilitates the initial positioning of the support 2 and the purlin slide rail 1, making it easy to hook on during installation and not easy to dislodge. The inverted fastening unit reduces the resistance of pressing in the inverted fastening, achieving seamless clamping. Through the three position limiting mechanisms of the semi-hanging pivot unit, the inverted fastening unit, and the support 2, the purlin slide rail 1 is limited in the vertical, horizontal, and vertical directions of the support 2, meeting the connection strength requirements while allowing movement in the rearward direction.

[0031] The purlin assembly 100 of the present invention has the following beneficial technical effects:

[0032] 1. The support 2 is installed on the purlin slide rail 1 through a semi-hanging shaft unit and an inverted buckle unit. It can be quickly assembled by simply pressing without tools, reducing the difficulty of manual operation. After the support 2 is fixed to the purlin slide rail 1, there are limit positions in the upper, lower and left and right directions, so it will not be disengaged and the connection stability is guaranteed.

[0033] 2. The purlin slide rail 1 and the support 2 are designed separately. When the support 2 is snapped in, it can slide and be finely adjusted along the purlin slide rail 1. The installation distance can be adjusted as needed on the construction site.

[0034] 3. The punching holes of support 2 can be prefabricated to avoid on-site drilling, thereby improving production efficiency and on-site installation efficiency.

[0035] 4. The purlins have eliminated the traditional folded edges, resulting in a smaller overall volume, reduced material waste, lower aluminum usage, and lower costs.

[0036] In this invention, the purlin slide rail 1 includes a main body 11 with a U-shaped cross-section; the support 2 includes a base plate 21; the semi-hanging pivot unit includes a first hook 12 and a second hook 22 that cooperate with each other, the first hook 12 being integrally formed on one side of the main body 11, and the second hook 22 extending to form the upper surface of the middle part of the base plate 21; the buckle unit includes a buckle angle 13 and a Z-shaped buckle plate 23 that cooperate with each other, the buckle angle 13 being integrally formed on the other side of the main body 11. The Z-shaped buckle 23 is integrally formed on the upper surface of the middle part of the base plate 21. The second hook 22 and the Z-shaped buckle 23 are arranged opposite to each other. The Z-shaped buckle 23 has an inverted step 24 that cooperates with the inverted angle 13. The Z-shaped buckle 23 includes an inverted end and a connecting end. The connecting end is integrally connected to the base plate 21. The inverted end cooperates with the inverted angle 13. The lower surface of the inverted angle 13 is an inclined surface. The inverted end is first pressed along the inclined surface, and finally the inverted step 24 is snapped into the upper surface of the inverted angle 13.

[0037] The semi-hung pivot unit and the inverted buckle unit form a multi-directional limiting mechanism, improving tensile strength and ensuring that the buckle will not come loose in strong winds. The semi-hung pivot unit achieves the initial positioning, and the inverted buckle angle 13 of the inverted buckle unit cooperates with the Z-shaped buckle plate 23 to reduce the inverted buckle pressure, making the pressing smoother and achieving "seamless clamping" to avoid installation jamming. All semi-hung pivot units and inverted buckle units are integrally molded, simplifying mold development and making them suitable for mass extrusion or stamping production.

[0038] In this invention, the space between the second hook 22 and the Z-shaped buckle plate 23 forms a receiving cavity 25 for accommodating the main body 11. A relief groove 26 communicating with the receiving cavity 25 is recessed on the upper surface of the support plate 21, and the relief groove 26 is positioned close to the second hook 22. The relief groove 26 is designed to avoid interference with the first hook 12 when the support 2 rotates, preventing rotational jamming. While maintaining structural strength, it also reduces the cross-sectional area of ​​the support 2, saving materials and lowering costs.

[0039] In this invention, the base plate 21 has a first extension plate 27 and a second extension plate 28 extending from both sides. The first extension plate 27 has a first punch 271, and the second extension plate 28 has a second punch 281. The first punch 271 and the second punch 281 are pre-punched, completely eliminating the on-site drilling process and improving installation efficiency.

[0040] Reference Appendix Figure 9 As shown, the present invention also provides an installation process for a purlin assembly 100 for quick installation on photovoltaic roofs. This assembly process is designed for corrugated steel roofs with essentially uniform corrugated steel roof crest spacing and includes the following steps:

[0041] S1: Align the second hook 22 with the first hook 12, so that the support 2 and the purlin slide rail 1 are connected for the first time through the semi-hanging shaft unit;

[0042] S2: The support 2 rotates around the semi-hanging shaft unit. The end of the Z-shaped buckle plate 23 on the right side of the support 2 slides upward along the inclined surface of the inverted buckle angle 13. Finally, the inverted step 24 is inverted onto the upper surface of the inverted buckle angle 13, so that the support 2 and the purlin slide rail 1 are assembled by the inverted buckle unit for the second time.

[0043] S3: As needed, the support 2 can be slid along the purlin slide rail 1 for fine adjustment to accommodate different installation spacing; the support 2 is locked to the corrugated steel roof by bolt assembly 3 (or self-tapping screws) at the first punch 271 and the second punch 281.

[0044] The installation process of the purlin assembly 100 is extremely simplified, consisting of three steps: hook, rotation, and fastening. This reduces on-site installation steps and eliminates the need for drilling. Single-person operation is quick and greatly improves installation efficiency.

[0045] Reference Appendix Figure 10 As shown, the present invention also provides another installation process for a purlin assembly 100 for quick installation on photovoltaic roofs. This assembly process is designed for situations where the corrugation spacing of corrugated steel roofs is inconsistent, and includes the following steps:

[0046] S1: First, fix the two supports 2 to the crest of the corrugated steel sheet using bolt assembly 3 (or self-tapping screws); align the first hook 12 with the second hook 22, so that the support 2 and the purlin slide rail 1 are connected by the first hook through the semi-hanging shaft unit;

[0047] S2: The purlin slide rail 1 rotates around the semi-hanging pivot unit, and the inclined surface of the inverted angle 13 presses against the inverted end of the Z-shaped buckle plate 23. Finally, the Z-shaped buckle plate 23 is fastened onto the inverted step 24, so that the support 2 and the purlin slide rail 1 are assembled by the second fastening of the inverted unit.

[0048] The two purlin assembly 100 installation processes of the present invention can be combined to improve installation efficiency while also being compatible with some special conditions at the installation site, ensuring smooth installation.
