Description

Technical Field

[0001] The utility model belongs to the technical field of roof walking paths and relates to an assembled path system. Background Art

[0002] Most of the existing path systems supporting photovoltaic projects are made of fiberglass grids, which generally show powdering and rusting after 3 - 5 years. The photovoltaic roof includes a metal roof and photovoltaic modules installed on the metal roof, and the service life of the photovoltaic roof is 25 - 30 years. It can be seen that the existing path systems cannot match the service life of the photovoltaic roof in terms of material and service life, resulting in multiple replacements or repairs in the middle, increasing the operation and maintenance costs. Moreover, if powdering and rusting occur, it will further damage the coating layer of the metal roof, leading to the damage of the roof system and potential water leakage problems.

[0003] In summary, the main disadvantages of this kind of path include:

[0004] (1) Short service life cycle, requiring frequent replacement;

[0005] (2) The corrosion resistance of the material itself is insufficient, indirectly damaging the original roof and increasing the risk of water leakage.

[0006] Patent CN220928451U discloses a roof walking path, including a mounting member. A square tube is fixedly installed inside the mounting member, a top plate is fixedly installed on the top of the mounting member, anti-slip grooves are formed on the outer surface of the top plate, a fixed base is fixedly connected to the bottom of the mounting member, an outward expansion groove is formed inside the fixed base, a fixed block is fixedly installed on the top of the top plate, a hanging ring is hinged to the outside of the fixed block, and the top plate and the fixed base are both made of aluminum alloy material, and the thickness of the top plate is 2 mm. Although this patent uses aluminum alloy material, the roof is generally made of galvanized or aluminum-zinc plated material. When two different metals come into contact and are simultaneously in an electrolyte, electrochemical corrosion is extremely likely to occur. Moreover, the top plate is directly installed on the roof through the fixed base. When using a large-area continuous fixed base, when the walking direction of the top plate is perpendicular to the arch of the roof, due to the gap between the fixed base and the adjacent arch being unable to be contacted, it is easy to cause damage to the roof due to uneven stress.

[0007] Patent CN208105690U discloses a system for connecting metal roof panels to roof equipment or roof walkways, mainly including roof steel beams, roof purlins, a lower metal roof panel, a roof insulation layer, an upper metal roof panel, C-shaped steel, and a connecting and fixing structure. The roof purlins are laid on the roof steel beams, the roof insulation layer is placed between the upper metal roof panel and the lower metal roof panel, the bottom end of the connecting and fixing structure is installed on the upper metal roof panel, and the top end of the connecting and fixing structure is connected to the C-shaped steel. However, this patent only addresses how the C-shaped steel is fixedly connected to the upper roof panel, without considering the fixing method of the walkway system on the C-shaped steel; secondly, it has poor adaptability, and is not suitable for T-shaped tiles or concealed fastener metal roofing systems except for standing seam roofing systems; in addition, the inverted U-shaped aluminum ingots need to be fastened to the protruding slope peaks, and when the slope peaks are large, a large area of ​​inverted U-shaped aluminum ingots is required, which wastes materials. It also needs to be fixed in conjunction with fixed supports, making the installation complicated, and like the aforementioned patent, it is not suitable when the direction of the C-shaped steel is parallel to the slope peaks. Utility Model Content

[0008] The purpose of this invention is to overcome at least one of the defects of the prior art and provide a prefabricated walkway system. This invention saves materials, has high connection strength between components, and high strength when installed on a metal roof.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0017] As a preferred technical solution, the inverted U-shaped top edge of the base is provided with several base slots, and the appropriate installation position of the base can be selected by choosing the appropriate base slot.

[0018] Furthermore, the bolts pass through the walkway slots, purlin slots, and base slots to install the metal walkway, purlins, and base.

[0019] As a preferred technical solution, the length of the base is greater than that of the purlin, ensuring that the pressure is stably transmitted to the arch installation point when the installation direction of the purlin is parallel to the arch.

The metal walkway is installed on the arch through the base with one base slot in the middle, and the metal walkway is installed on the arch through the base with two base slots at both ends. Adjacent metal walkways are installed through the two base slots of the same base respectively.

[0022] Furthermore, the bolts pass through the walkway slots and purlin slots to install the metal walkway and purlins, and the bolts pass through the purlin slots and base slots to install the purlins and bases.

[0023] As a preferred technical solution, the length of the base is less than that of the metal walkway, ensuring that the pressure at both ends of the purlin is transmitted to the arch installation point when the installation direction of the purlin is perpendicular to the arch, while saving material as much as possible for the base.

[0024] Furthermore, a support plate is provided within the U-shaped space of the purlin, and the bolts pass through the walkway slots, the support plate, and the purlin slots to install the metal walkway and purlin.
