Description

FIELD OF TECHNOLOGY

The present disclosure relates generally to a convex plastic panel used in a roofing system, and more particularly to an extruded convex light-transmitting plastic panel used in a metal roofing system.

LEVEL OF TECHNOLOGY

Metal has been the preferred roofing coating for households, commercial, agricultural, office and industrial buildings for many years. A wide range of substrates, colors, textures and profiles are available for metal roofing. Although different in appearance, metal roofing shares many characteristics, such as long service life, the ability to drain water from the roof surface, strength, recyclability, fire resistance and weather resistance.

It is often desirable that buildings with a metal roof system be fitted with veto transmissive plastic panels / skylights to allow natural light into the building, allowing sunlight to enter the building through vetoed transmissive plastic panels. These veto transmissive plastic panels are usually made of transparent or translucent sheeting and can be produced in a variety of shapes including flat, domed, pyramidal, trapezoidal, or can have a profile similar to that of metal roofing panels. Light-transmitting plastic panels usually have connection sections to seal the light-transmitting plastic panels to the metal roofing system.

An example of such plastic panels is disclosed in US Pat. No. 4,573,300, which discloses flat extruded plastic panels with standing folds protruding at the edges of the plastic panels at right angles. These plastic panels are connected to one another in a standing seam with a connector, and the prongs or latches of the standing seams face the inside of the plastic panels to engage the connector.

Another example in US Patent Application No. US2004 / 0159054 discloses a light transmissive sheet having a profile similar to that of a metal roof and including trapezoidal domes and trapezoidal wings. The light-transmitting sheet is attached to the metal roof by fastening the wings with a veto of the transmitting sheet to the dome of the metal roof with fasteners. In yet another example, EP 2,778,313 discloses a sail-shaped polycarbonate roof skylight that includes connection portions with insulating tabs at both ends of the polycarbonate skylight to facilitate attaching the polycarbonate skylight to the roof.

In prior art veto solutions, transmissive plastic panels typically include connecting portions in the form of metal flaps or fenders. These metal flaps are secured using fasteners or screws to mount the clear plastic panels to the metal roofing system. This method of vetoing transmissive plastic panels into metal roofing systems using fasteners has led to several problems.

During a typical day, the metal panels of the metal roofing system and other parts of the metal roof system will expand and contract due to the temperature difference. However, due to the different coefficients of thermal expansion of metal panels and light-transmitting plastic panels, deformations or even cracks will appear, which will lead to leaks in the metal roofing system. Since the transmissive plastic panels are attached to the metal roofing system with screws or fasteners, this gives the entire assembly a rigidity that does not allow the translucent plastic panels to expand or contract freely. But light-transmitting plastic panels, such as polycarbonate, do expand and contract, since the linear coefficient of thermal expansion (a) of polycarbonate at 23 ° C is 65-70 × 10 ^-6 / ° C, which is much higher (about 3 times) than that of metal, thus becoming exposed to tensile and compressive forces that warp, deform or damage the transparent plastic panels.

In light of the foregoing, at least one object is to prevent warping, warping, or damage to the light transmissive plastic panel or convex plastic panel used with a metal roofing system. Another goal is to offer a convex plastic panel that is installed on a metal roofing system using a connecting profile, thereby allowing the convex plastic panel to expand or contract freely. Other objects, such as desirable features and characteristics, will become apparent from the following disclosure and detailed description, and the appended claims, taken in conjunction with the accompanying drawings and this prior art description.

Also, embodiments of the invention mention the use of an X-shaped, honeycomb, two-cell or multi-cell structure of the ribbed structure 102, but any other commonly used ribbed structures, such as parallel, diagonal, triangular, trapezoidal, diamond-shaped, or any combination thereof, but without violation of the scope of the invention.

Although preferred embodiments of the present invention utilize a multi-tooth lock 104B and a multi-toothed flange 111, a single-tooth lock and a single-tooth flange may be used instead.

While various embodiments of the present invention have been described above, it should be understood that they are presented by way of example only and not for limitation. Those skilled in the art will understand that various changes can be made to their shape and detail, but without violating the spirit and scope of the invention.
