Novel connection and installation method between photovoltaic bracket and trapezoidal profiled steel plate roof

Abstract

The invention belongs to the technical field of house photovoltaic equipment, and discloses a novel connection and installation method between a photovoltaic bracket and a trapezoidal profiled steel plate roof. The method comprises the steps: removing dust from the top surface of the trapezoidal profiled steel plate, laying a rubber gasket, placing Z-shaped connectors and driving in 2-3 self-tapping nails; fixing the photovoltaic bracket by stainless steel bolts, sealing the self-tapping nail caps by a silicone sealant and installing a photovoltaic module; connecting the photovoltaic module with the roof board by using the Z-shaped connectors and guide rails; and fixing the self-tapping nails by penetrating through the top surface of the trapezoidal profiled steel plate, and transmitting the load of the photovoltaic module to the roof purlins through the Z-shaped connectors and then to the roof truss steel beams. The method has the advantages of convenient and simple construction; short construction period; high drawing resistance; and using the silicone sealant and the rubber gasket for double waterproofing so that there is no risk of water leakage on the roof.

Description

technical field [0001] The invention belongs to the technical field of house photovoltaic equipment, and in particular relates to a connection and installation method between a novel photovoltaic support and a trapezoidal profiled steel plate roof. Background technique [0002] Currently, the closest prior art: [0003] Structural adhesive bonding: In order to increase the bonding force, it is necessary to increase the contact surface between the fixture and the color steel plate, so a large figure-eight fixture is used, which is costly. [0004] The construction period is long, and there are requirements for the ambient temperature and humidity of the construction; after the glue is glued, it needs to be dried in a sunny day (usually 24 hours) before the bracket guide rail can be installed. [0005] The quality of the structural glue is uneven. Under the long-term outdoor environment, the fixture may loosen and fall off due to aging, cracking and deformation. [0006] Col...

AI Technical Summary

Problems solved by technology

[0010] (1) In the existing technology, the structural adhesive is easy to age and crack, causing the fixture to fall off; the connecting piece is a large figure-shaped fixture, and the cost is high

[0011] (2) Welding quality of cold welding connection cannot be guaranteed

[0012] (3) Conventional self-tapping nail connection, easy to cause roof leakage

[0013] Difficulties in solving the above technical problems: the connection form is not easy to choose, the high-quality and cheap connectors are not easy to design, and the roof waterproofing is not easy to solve
