technical field

The invention relates to a photovoltaic roof transfer fixture and a photovoltaic roof structure using the transfer fixture.

Background technique

With the development of the global economy, the problem of energy consumption has become increasingly prominent. As a clean renewable energy, solar energy has become one of the renewable energy sources encouraged by various countries. Solar photovoltaic roofing is the application of photovoltaic power generation systems that use solar energy to generate electricity The roof of the building, this method can not only improve the space utilization, but also install the solar power generation system on the roof to reduce the temperature rise of the roof and reduce the air conditioning load, etc. Therefore, the photovoltaic roof has become an important technology in the field of building energy conservation. Photovoltaic roofing technology mainly uses photovoltaic brackets to erect photovoltaic modules on the roof, which needs to be fixedly connected to the roof. The traditional method is to slot the roof or fix it with bolts, but this will inevitably damage the roof structure.

The transfer fixture is composed of two separate left clamping arms and right clamping arms connected by locking bolts. When in use, the two clamping arms first need to be placed on both sides of the roof rib, and then the two The perforations on the two clamping arms are aligned and locked with locking bolts, so the operation process is inconvenient, especially not suitable for high-altitude operations; secondly, the two clamping arms that are set separately are scattered during transportation, so they are easy to lose.
