Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a novel node based on BIPV photovoltaic reinforcement belongs to the technical field of building steel structure. BACKGROUND
[0002] With the increasing demand of industrial electricity and the vigorous development of photovoltaic new energy industry, the concept of BIPV (building photovoltaic integration) gets more and more widespread attention in the field of industrial building, so how to reinforce photovoltaic for old industrial plants becomes a heavy and difficult point. Considering not affecting the normal operation of the existing plant, it is obviously not an effective method to reinforce the beam column of the steel structure inside. Therefore, it is a relatively reasonable scheme to adopt the roof truss form and avoid the impact on the production and storage of the plant by external reinforcement. The biggest feature of the structure is that the original plant purlin and roof panel are not removed, the steel beam is used as the bottom chord of the truss for reinforcement, and under the premise of ensuring the reasonable structure, the influence of construction on the normal use function of the plant is avoided, and the construction cost is greatly reduced. However, due to the connection requirement of the truss web member and the steel beam, it is difficult to avoid the connection by punching holes in the roof, and the connection mode of the web member and the bottom chord of the traditional truss will cause the roof panel to have too large opening, which leads to the difficulty of roof waterproofing and increases the construction difficulty and cost. Therefore, how to correctly handle the connection mode of the web member and the steel beam, reduce the roof opening area, and reduce the construction difficulty and cost under the premise of good roof waterproofing work has become the top priority for structural engineers.
