Description

Technical Field

[0001] The invention relates to the technical field of composite metal plate production, in particular to production equipment for polymer composite metal plates. Background Art

[0002] The mandatory engineering construction specification "General Specification for Waterproofing of Buildings and Municipal Engineering" (GB55030-2022) implemented on April 1, 2023 requires that the waterproofing practices of metal roofing projects should comply with the following regulations: When a single layer of exposed waterproof membranes such as polyvinyl chloride waterproof membranes (PVC), thermoplastic polyolefin waterproof membranes (TPO), and ethylene propylene diene monomer waterproof membranes (EPDM) are used on the roof metal plate base, the thickness of the waterproof membrane should not be less than 1.8mm for the first level waterproofing, 1.5mm for the second level waterproofing, and 1.2mm for the third level waterproofing.

[0003] From the above regulations, it can be seen that polymer waterproofing membranes have become an essential component in the construction of metal roofing systems. Due to the characteristics of the metal roofing installation process, if the polymer waterproofing membrane is laid under the roof, the self-tapping screws that fix the roof panel supports will inevitably penetrate the waterproofing membrane. Even if each nail hole is repaired, after the metal roof panel installation and covering is completed, the repaired nail holes will all be hidden under the roof. Once the nail holes are not repaired in place, the hidden dangers of leakage points will be basically impossible to find. In addition, the number of self-tapping screws used in the roof supports is huge. Repairing each nail hole will consume a lot of manpower and time, greatly increasing the construction cost of the metal roof; if the polymer waterproofing membrane is laid above the roof, the simplest and most reliable method is to bond the polymer waterproofing membrane to the metal plate to meet the requirements of mandatory engineering construction specifications.

[0004] In the existing technology, if photovoltaic power generation is combined with buildings, it will be able to effectively reduce building energy consumption, and it is installed on the roof or roof surface, does not require additional land, and saves land resources. However, the anti-corrosion performance of the corrugated steel sheets used in most metal roofs is generally 5-10 years, while the service life of a photovoltaic power station is more than 25 years. The service life of the two does not match. If the roof panels are replaced during the life of the photovoltaic power station, it will cause huge losses to the investors of the photovoltaic power station, seriously affecting the promotion and application of photovoltaic power stations on metal roofs. Outdoor polymer waterproof membranes (TPO, PVC) have been proven to have a service life of more than 25 years. Composite exposed TPO waterproof membranes to metal plates can not only meet the mandatory requirements of the "General Specification for Waterproofing of Buildings and Municipal Engineering" (GB 55030-2022), but also improve the anti-corrosion performance of metal roofs and meet the life cycle requirements of photovoltaic power stations. However, the raw material width of the corrugated sheet used in the metal roof is generally 1200mm-600mm, and the length is generally more than 30m, while the production width of polymer waterproof rolls such as TPO or PVC is mostly 2000-2500, and the length is generally 20m. The composite modulus of the two materials does not match and needs to be cut, resulting in waste. Summary of the invention
