Roof photovoltaic system bracket

The environment where roof photovoltaic brackets are installed includes sloped roofs and flat roofs. The installation must comply with the roof environment without damaging the inherent structure and self-waterproofing system. Roofing materials include glazed tiles, colored steel tiles, linoleum tiles, concrete surfaces, etc. Different bracket solutions are used for different roofing materials.

Roofs are divided into two types: slope and flat according to the angle of inclination. Therefore, there are many choices for the inclination angle of the roof photovoltaic system. For sloped roofs, they are usually laid flat to comply with the roof slope, or they can be arranged at a certain inclination with the roof. , but this approach is relatively complicated and has few cases; for flat roofs, there are two options: tiled and tilted at a certain angle.

Glazed tile roof bracket

Glazed tiles are building materials made from soft and hard raw materials such as alkaline earth and purple sand, which are extruded, molded and then fired. The material is brittle and has poor load-bearing capacity. When installing brackets, specially designed main support members are generally fixed to the lower roof of the glazed tiles to support the main beams and cross beams of the bracket. Support members such as connecting plates are usually designed with multiple openings to flexibly and effectively adjust the position of the bracket. The components and cross beams are crimped using aluminum alloy pressing blocks.

Color steel tile roof bracket

Color steel plate is a steel product formed by cold pressing or cold rolling of thin steel plate. The steel plate uses organic coated thin steel plate (or colored steel plate), galvanized thin steel plate, anti-corrosion thin steel plate (containing asbestos asphalt layer) or other thin steel plates.

Profiled steel plates have the advantages of light unit weight, high strength, good seismic performance, fast construction, and beautiful appearance. They are good building materials and components. They are mainly used for building envelopes, floors, and other structures.

Roofing color steel tiles are generally divided into: upright seam type, bite type (angle chi type), buckle type (hidden buckle type), and fastener connection (exposed nail type). Bayonet (hidden buckle) type Fixture connection (exposed nail type)
When installing a photovoltaic system on a color steel tile roof, the shape of the color steel tile and its load-bearing capacity must be fully considered to determine the bracket fixing method. The fixing method of the color steel tile roof bracket is mainly determined according to the shape of the color steel tile.

concrete roof supports

Concrete roof photovoltaic brackets are generally fixed at a fixed inclination angle, and can also be arranged in a tiled manner. This type of roof fixation method is mainly fixed by concrete foundation and standardized fixed connectors, and is divided into two methods: cast-in-place and pre-cast.

The cast-in-place rectangular foundation on the concrete roof is suitable for areas and roofs with small roof load and high wind load; as shown in the figure below: 1. The rectangular foundation is connected to the roof with chemical anchors; 2. Standardized fixed connectors are installed on the rectangular foundation; 3. Assembly of brackets and components.
