[0059] For the repair of wooden roof structures, the main focus is on the scientific and effective treatment of cracked, bent, and failed roof support structures. Wooden structural components are prone to deterioration due to long-term exposure to damp environments, especially at the base of columns and eaves (because the base of columns is enclosed within the walls and lacks drying or ventilation, it will rot over time), leading to a decline in the material properties of the wooden structure and rendering it unsuitable for residential use. The main methods used are patching and replacement, depending on the extent of the damage. For minor damage, similar materials are carefully selected for repair, maintaining the original rural architectural structure. For severely damaged areas, structural splicing (replacing the support structure, erecting brackets, and laying photovoltaic modules) can be considered in conjunction with the efficiency of photovoltaic modules and the aesthetic effect of the roof. Ventilation gaps can also be created using photovoltaic panels and other components to further prevent further structural deterioration.
