Roof photovoltaic support structure system without counterweight foundation

Abstract

The invention relates to the field of roof photovoltaic installation systems, in particular to a roof photovoltaic support structure system without a counterweight foundation. Comprising a house body, parapet walls are arranged on a roof of the house body, a plurality of embedded parts are fixed to the parapet walls on the left side and the right side in an embedded mode, vertical ejector rods are connected to the upper ends of the embedded parts through quick mounting devices, the ejector rods on the left side are higher than the ejector rods on the right side, and the upper ends of the ejector rods on the left side are connected with the left ends of supporting rods through first positioning devices; the upper end of the right ejector rod is connected with the right end of the supporting rod through a second positioning device, a plurality of supporting rods are connected to the portion, between the left ejector rod and the right ejector rod, of the supporting rod, and supporting devices corresponding to the supporting rods are arranged on the roof of the house body. The device is convenient to disassemble and assemble, does not need to add a balance weight, does not need to damage a waterproof layer of a roof, does not need too many loose parts in the installation process, can improve the installation efficiency, is long in service life, can recover the supporting rods into the supporting rods, and is convenient to hoist.

Description

technical field [0001] The invention relates to the field of a roof photovoltaic installation system, in particular to a roof photovoltaic support structure system without a counterweight foundation. Background technique [0002] For the anchoring of photovoltaic support on the roof, there are currently two main solutions; 1) Set a counterweight foundation on the column of the photovoltaic support, mostly a concrete cube or cylindrical support pier, anchor the photovoltaic system by its own weight, and resist the wind load. 2) Set up embedded parts or expansion bolts to connect with the roof structure layer to anchor the photovoltaic system. Disadvantages: Option 1 will greatly increase the roof load, resulting in an increase in the thickness of the roof panel or the amount of reinforcement, increasing the cost of the project; if the photovoltaic system is added to the existing roof, due to the large increase in load, it will often exceed the original roof design Carrying c...

Problems solved by technology

Disadvantages: Option 1 will greatly increase the roof load, resulting in an increase in the thickness of the roof panel or the amount of reinforcement, increasing the cost of the project; if the photovoltaic system is added to the existing roof, due to the large increase in load, it will often exceed the original roof design Carrying capacity, which in turn prevents the project from proceeding

The installation of embedded parts in Option 2 will lead to difficulties in the construction of the roof surface in the later stage, and will also affect the effect of the roof waterproof layer; if the photovoltaic system is added to the existing roof and anchored by setting expansion bolts, the original roof will inevitably be damaged Insulation and waterproofing
