Cleaning the roof debris, use a measuring tape to measure the installation position of the foundation on the roof, and place the foundation;

Use a percussion drill to drill holes in the cement foundation. The depth of the hole is determined by the thickness of the foundation and the length of the bolt. The bolt diameter is M10. (The pre-embedded bolts are used to deal with impurities on the threads);

Put the expansion bolt into the hole, use a non-metal hammer such as a wooden hammer or a leather hammer to gently tap the bolt into the hole, with a distance of 30mm from the hole;

Installing the bottom beam or foundation, align the bottom beam hole or foundation hole with the bolt and use a wrench to tighten the nut; (fix other foundation foundations according to the above method)

Measuring the installation position of the rear column according to the angle of the bracket, and use bolts to fix the base to the rear column;

Fix the inclined beam, use the corner connection to fix the rear pillar, and use the bolt to connect the inclined beam to the base;

Fixing the keel, determine the installation position of the keel according to the installation hole of the component, keep the distance between the keel and the installation hole at ±100mm, and the frame at both ends of the component is 200-300mm away from the inclined beam. Use special-shaped nuts to fix the keel on the inclined beam;

Before installing the module, determine the installation height of the module. The glass surface of the lower end of the module is 300mm away from the ground. Use the side pressure block to fix the module. First fix the lower end pressure block to prevent the module from sliding. The module frame is 20-30mm away from the two ends of the keel. Two people are required to cooperate when fixing, and use a wire drawing method or a level to determine the overall parallelism of the components.
