AI Technical Summary

Technical Problem

Photovoltaic roofs are prone to wind shedding and overturning under strong typhoons and harsh climate conditions. In the prior art, the inner layer structure of the photovoltaic roof is not firmly fixed during installation, resulting in insufficient wind shedding resistance.

Method used

A connection structure including U-shaped steel and a clamping member is adopted, and is connected to the fixing bolt rod of the top longitudinal rectangular purlin through U-shaped steel, and is fixed to the bottom transverse rectangular purlin by bolting the clamping member to ensure a firm connection between the two.

Benefits of technology

The firm fixation of photovoltaic roof purlins is achieved, the wind resistance is improved, and the wind removal and overturning accidents of the roof in harsh climatic conditions are avoided.

Abstract

The utility model discloses a connecting structure for fixing a photovoltaic roof purlin, the connecting structure is used for fixing a top longitudinal rectangular purlin and a bottom transverse rectangular purlin, the connecting structure comprises U-shaped steel and a hoop piece, the top longitudinal rectangular purlin is fixed in a groove in the middle of the U-shaped steel, and the hoop piece is fixed in the groove in the middle of the U-shaped steel. The hoop piece is fixed to the bottom transverse rectangular purline, and the hoop piece and the bottom of the U-shaped steel are fixed through a stainless steel bolt and matched with a nut. The U-shaped steel is connected with the top longitudinal rectangular purline through the fixing bolt rod, and then is connected with the bottom transverse rectangular purline through the hoop piece and the bolt group, so that the top longitudinal rectangular purline and the bottom transverse rectangular purline are fixedly clamped together, and force transmission is better realized; and the problem that the photovoltaic roof purline is not firmly fixed when being fixedly mounted is also solved.
