BIPV photovoltaic roof system and construction method

Abstract

The invention discloses a BIPV photovoltaic roof system and a construction method, and belongs to the field of roof construction, and the BIPV photovoltaic roof system comprises a roof structure, a waterproof layer laid on the roof structure, a keel supporting system penetrating through the waterproof layer and connected to the roof structure, photovoltaic modules laid on the keel supporting system, and decorative rods covering the left and right adjacent photovoltaic modules. The decorative rod is of a barrel-shaped structure which is narrow in head and wide in tail and provided with an opening in the lower portion, and the decorative rod comprises vertical clamping parts on the two sides and a decorative part between the two clamping parts. The tail parts of the decorative rods are provided with inserting clamping edges, and the decorative rods connected end to end are inserted through the inserting clamping edges in a matched manner; an assembly bayonet with a high tail and a low head is formed in the lower part of the decorative rod, and the bayonet depth of the assembly bayonet is gradually increased from the tail to the head; the lower frame of the photovoltaic module is clamped on the module bayonet; and a sealing plug is arranged on the decorative rod close to the cornice. The problems that an existing photovoltaic roof is generally single in structural modeling, small in roof application range, poor in heat dissipation performance and poor in waterproof leakproofness are solved.

Description

Technical field [0001] The present invention belongs to the field of roofing construction, specifically relates to a BIPV photovoltaic roofing system and construction method. Background [0002] BIPV photovoltaic building integration building is the architectural concept of perfectly combining solar energy and architectural design, and skillfully introduces solar energy devices on the basis of not affecting the overall architectural design style and taste to complete the green energy supply of the building. But until now, subject to factors such as photovoltaic module modeling, power generation efficiency and installation and fixing methods, there are very few BIPV buildings that truly meet the requirements of architectural designers. In the published distributed photovoltaic roofing technology scheme, there is a lot of discussion about the application of photovoltaic in industrial plants or ordinary commercial roofing, these technologies to meet the basic power generation funct...
