Description

TECHNICAL FIELD The present invention relates to an installation structure for installing and fixing a solar module on the upper surface of a roof made of sandwich panels, and more specifically, for firmly installing the solar module on the upper surface of the roof. Installation for solar module roof installation with water leakage prevention function that can block (bypass) the path of rainwater flowing into the punched part punched by screws (pieces), bolts, anchors, etc. to prevent water leakage at the punched part Regarding structures.

Recently, environment-friendly solar modules that use solar energy instead of fossil energy have been widely used. Since the power production efficiency of such a solar module is proportional to the area of the light collecting plate, the economic efficiency is greatly reduced when it is installed on general ground. It is installed and operated on the sloping roof of a warehouse-type building.

Warehouse-type buildings are usually large in scale and require insulation, so they are constructed using sandwich panels, which are relatively inexpensive to construct. These sandwich panels are formed by bonding styrene foam between thin upper and lower plate members, and the upper plate member is repeatedly formed with protrusions and recesses to guide the flow of rainwater and reinforce strength.

However, when a solar module is installed on a roof made of sandwich panels, it is vulnerable to water leakage. Solar modules are fastened and fixed on the upper surface of the sandwich panel using fastening members such as screws (pieces), bolts or anchors. Rainwater flows in and leaks occur.

Thus, many prior arts have been proposed to prevent water leakage that occurs when solar modules are installed on a sandwich panel roof using fastening members. , a bracket for roof mounting of photovoltaic modules was proposed.

A bracket proposed in Korean Patent No. 10-2129979 couples a solar module installation plate to a structure including a lower plate, a vertical plate and an upper plate, and the solar module installation plate is formed on the lower plate. By blocking the through holes and the punching holes (through holes) formed in the upper plate, resin plate, and lower plate, water leakage in holes or grooves formed by fastening members penetrating the roof is prevented.

However, the structure proposed in Korean Patent No. 10-2129979 is a structure in which the holes and grooves formed in the solar module installation structure are closed with a solar module installation plate to seal it, and it is difficult to use for a long period of time. When weathering and abrasion occurs due to exposure to the external environment (rain, wind, sunlight, etc.), the sealing force is significantly reduced, and when rainwater flows in, water leakage inevitably occurs.

In addition, in the structure proposed in Korean Registered Patent No. 10-2129979, the structure of the solar module mounting plate and the structure is somewhat complicated and difficult to manufacture, and the solar module is fixed to the guide groove and the airtight groove formed on the lower plate. Since the member and the airtight member must be inserted, and they must be sandwiched and connected to each other, there is a problem that the work is complicated, the construction is difficult, and the construction cost increases.

In addition, conventionally, various installation structures have been proposed to prevent rainwater leakage on the top surface of the roof where solar modules are installed, but most of them are roof punchings formed by bolts and anchors. There is absolutely no technology developed to prevent rainwater from flowing into the perforated part of the roof, which is the main cause of water leakage.
