Description

Assembled self-supporting photovoltaic side fascia

Technical Field

The invention relates to the technical field of assembled building external wall panels, in particular to an assembled self-bearing photovoltaic external wall panel.

Background

As a new energy application technology integrated with a building, a Building Integrated Photovoltaic (BIPV) technology is widely used. Conventional BIPV technology is typically retrofitted to existing buildings, but installing photovoltaic modules on existing roof or facade walls requires pre-installation of the module support structure, i.e. the rack. This kind of mounting means needs extra support material cost, and the big cycle of the installation degree of difficulty is long, and the installation cost is higher, can destroy original building's waterproof layer and heat preservation moreover, causes some irreversible damage to the wall body. The other BIPV technology is that the photovoltaic module replaces building materials to be used as a part of a building, namely the photovoltaic module is used for manufacturing a roof, an outer wall and a window of the building, although the integration level and the integration degree are high, the requirements on heat preservation, heat insulation, water resistance, safety and fire resistance of the photovoltaic module are high, and therefore the design difficulty is high and the cost is high.

For photovoltaic external wall panels, the existing patent technologies are generally divided into two types, the first type is to fix a wall body and a photovoltaic module by pre-embedded connecting members, for example, the prefabricated photovoltaic wall panel disclosed in chinese patent CN113958022a and the manufacturing method thereof, and the second type is to reserve a groove on a prefabricated concrete wall body and embed the photovoltaic module into the wall body, for example, the prefabricated concrete external wall and photovoltaic integrated member for an assembly type building disclosed in chinese patent CN 208088559U. The self gravity of the photovoltaic panel is transmitted to the wall body through the embedded connecting piece, so that higher requirements are provided for the strength, the rigidity and the installation mode of the connecting piece, and the material cost and the installation cost of the connecting piece limit the popularization and the application of the connecting piece to a certain extent. The groove is reserved on the wall body of the photovoltaic module, the gravity of the photovoltaic module is directly transmitted to the platform formed by the groove on the wall body, the cost of an installation support is saved, the safety is higher, but only one photovoltaic module can be vertically installed in one groove, if a plurality of modules are vertically installed, a plurality of grooves need to be vertically formed, enough width is reserved between the grooves and the grooves to bear the gravity of the photovoltaic panel, and therefore the power generation area of the wall surface is small.
