Background

As shown in fig. 1-2, a fixture type structure is usually adopted when a photovoltaic module is additionally installed on a steel tile roof in the prior art, and the fixture type structure includes a steel tile 1', a photovoltaic module 3', a keel support 2 'with a staggered structure, and a plurality of fixtures 4', the steel tile 1 'is laid and fixed on the roof, the photovoltaic module 3' is covered and arranged above the upper surface of the keel support 2', the plurality of fixtures 4' are distributed and fixed at the bottom of the keel support 2 'at intervals, and the keel support 2' is clamped and fixed on the top surface of the steel tile 1 'through the fixtures 4'. The photovoltaic module 3' is in the form of a traditional aluminum frame and the like, the installation and design specialties are low, small photovoltaic module suppliers can also produce the photovoltaic module, the market popularity is high, the existing problems are obvious, and the common suppliers are difficult to break through due to the limitations of technology, production and processing and the like. In general, the existing steel tile roofing has the following problems:

1. because the keel bracket 2 'is rigidly connected with the wave crest of the top surface of the steel tile 1' through the clamp 4', the concentrated stress is large, the steel tile 1' can stretch due to temperature change, and the keel bracket 2 'cannot freely stretch and deform, so that the steel tile 1' is easily damaged;

2. the photovoltaic module and the keel bracket 2' need to be fixed on the top surface of the steel tile 1' by means of a clamp 4 ';

3. the steel tile 1 'is exposed to the external environment of acid rain or corrosive liquid or gas for a long time, and even if the surface of the steel tile is coated with an anti-corrosion or anti-rust coating, the steel tile 1' gradually starts to be corroded to perforate along with the continuous corrosion of the environment, so that leakage is caused;

4. the point-type fixation of the clamp 4' is too large to resist wind uncovering.

The connecting column 7 '-1-2 is communicated with the upper end surface and the lower end surface of the bottom seat plate 7' -1-1 and is vertically communicated with the center of the bottom seat plate 7 '-1-1, the bottom of the connecting bracket 7' -2 is connected with the top of the connecting column 7 '-1-2, and the top is connected with the keel bracket 6'. Photovoltaic module covers and establishes above fossil fragments support 6 "upper surface. The bottom of the connecting column 7 ' -1-2 is also sequentially communicated with a TPO coiled material base plate 5 ', a heat insulation material layer 4', a steam insulation material layer 3' and a flexible steel plate base layer 2 special for a roof, and extends out of the bottom surface of the special flexible steel plate base layer 2' of the roof. And the riveting piece 7 ' -1-3 is arranged at the bottom of the connecting column 7 ' -1-2 and is positioned at the bottom of the special flexible steel plate base layer 2' of the roof, and the photovoltaic support is locked on the single-layer roof.

The photovoltaic supports used on single-layer roofs have the following disadvantages:

1. the application range is narrow, and the composite material can not be used for a steel tile roof;

2. the single-layer roof is perforated and installed, so that water leakage is easy to occur;

3. drilling in advance is needed, and the installation is inconvenient;

4. high cost and is not suitable for large-area application.

The photovoltaic support that can be general in steel tile roofing and individual layer roofing does not have on the existing market promptly, and because the installation of punching need lead to the roofing to leak easily when just having the use of photovoltaic support.

Therefore, it is an urgent task to provide a building attached photovoltaic support with wide application range, good waterproof performance, uneasy damage, flexible installation and convenient construction.
