Photovoltaic building integrated waterproof system and an installation method thereof

Abstract

The invention relates to a photovoltaic building integrated waterproof system and installation method thereof, and belongs to the technical field of photovoltaic buildings. The system comprises a ridge and roofs obliquely arranged on the two sides of the ridge, roof layer purlines are arranged on the roofs, a ridge cover plate is arranged at the top of the ridge, and longitudinal water guide grooves are connected and installed on the roof layer purlines; the longitudinal water guide groove is of a concave groove structure, and the middle part of the longitudinal water guide groove is concave upwards and convex downwards; the two sides of the downward-protruding part of the bottom of the groove protrude outwards and are clamped with a water guide groove clamping block, and the water guide groove clamping block is connected with a roof layer purline structure; an adapter is arranged in the upper concave part of the top of the groove and clamped with the two ends of a bottom foot of the adapter, and the top of the adapter is connected with an installation pressing block; longitudinal sealing rubber strips are arranged above the longitudinal water guiding grooves, photovoltaic assemblies are installed above the longitudinal sealing rubber strips, transverse water guiding grooves are installed below the photovoltaic assemblies, and transverse sealing rubber strips are arranged on the side faces of the photovoltaic assemblies. Reliable water prevention between assembly gaps is achieved, installation is convenient and fast, and thermal expansion and cold contraction of a building are met.

Description

technical field [0001] The invention relates to a photovoltaic building integrated waterproof system and an installation method thereof, belonging to the technical field of photovoltaic buildings. Background technique [0002] Under the existing technology, the integrated system of photovoltaic buildings relies on the ridge setting. At present, self-tapping screws or aluminum alloy are mostly used for fixing in the market. However, the fixed position of the self-tapping screw is easy to rust and fall off after a long time, and loses its fastening effect; the aluminum alloy has no advantages in terms of cost and structural strength, and only considers the photovoltaic system and waterproofing, without considering the performance requirements of the building. [0003] The Chinese patent with the patent publication number CN113700234A discloses a building integrated photovoltaic system. The roof ridge and two roofs are inclined on the left and right sides of the roof ridge. Th...

Problems solved by technology

[0004] The roof ridge mentioned in the above patent can not only carry accumulated water, but also effectively carry the weight of the operator, so that the operator can use the criss-crossing maintenance channels and the roof ridge to carry out operation and maintenance operations, effectively improving the operation and maintenance effect of the photovoltaic building system However, the BIPV system in this patent cannot adapt to the thermal expansion and contraction of the building, and its firmness is not enough. After a long time, the fixed position of the self-tapping screw is easy to rust and fall off, and thermal expansion and contraction cause shearing and loss of fastening In addition, the water guide groove and the force-bearing components of this patent are designed separately, which is troublesome to install; this patent is also waterproof through waterproof covers, rubber plugs, glue, etc., and the waterproof performance is not reliable enough
