Description

Technical Field

[0001] The invention relates to a novel node based on BIPV photovoltaic reinforcement and an installation method thereof, belonging to the technical field of building steel structures. Background Art

[0002] With the increasing demand for industrial electricity and the vigorous development of the photovoltaic new energy industry, the concept of BIPV (building integrated photovoltaic) has received more and more widespread attention in the field of industrial buildings. Therefore, how to carry out photovoltaic reinforcement in old industrial plants has become a key and difficult point. Considering that it does not affect the normal operation of the existing plant, it is obviously not an effective way to reinforce the beams and columns of the steel structure internally. Therefore, it is a more reasonable solution to adopt the form of roof trusses and use external reinforcement to avoid affecting the production and reserves of the plant. The biggest feature of its structure is that without dismantling the purlins and roof panels of the original plant, the steel beams are used as the lower chords of the trusses for reinforcement. Under the premise of ensuring a reasonable structure, it not only avoids the impact of construction on the normal use function of the plant, but also greatly reduces the construction cost. However, due to the need to connect the truss web and the steel beam, it is inevitable to connect them by drilling holes in the roof. Among them, the connection method of the web and the lower chord of the traditional truss will cause the roof panel opening to be too large, resulting in difficulty in roof waterproofing, increasing the difficulty and cost of construction. Therefore, how to correctly handle the connection method between the web members and the steel beams, reduce the area of ​​the roof opening, and reduce the difficulty and cost of construction while doing a good job of roof waterproofing has become a top priority for structural engineers.

[0003] Based on this, the present invention is proposed. Summary of the invention

[0004] In view of the above-mentioned technical problems of the prior art, the purpose of the present invention is to provide a new type of node based on BIPV photovoltaic reinforcement and its installation method, which is a connection node with reasonable force, simple connection, easy waterproofing, and meets the functional requirements of use and structural force transmission.

[0005] To achieve the above object, the present invention is implemented by the following technical solutions: A new type of node based on BIPV photovoltaic reinforcement includes a steel beam, on which a steel circular tube straight web is installed, and steel circular tube diagonal webs are installed on both sides of the steel circular tube straight web. An upper chord is fixed to the upper end of the steel circular tube diagonal web, and a lower chord is fixed to the lower end of the steel circular tube diagonal web. A steel beam stiffening plate is provided below the steel circular tube straight web.

[0006] The diameter of the steel round tube straight web member is greater than the diameter of the steel round tube oblique web member.

[0007] The steel round tube diagonal web members are connected to the steel round tube straight web members by welding, and the steel round tube diagonal web members are connected to the upper chord members by welding.

[0008] A method for installing a new node based on BIPV photovoltaic reinforcement includes the following steps: (1) After accurate positioning on the steel round tube straight web bar, weld the steel round tube diagonal web bar to the left and right sides of the steel round tube straight web bar; (2) Check the installation position of the steel round tube straight web member and the length of the steel round tube diagonal web member between the upper and lower chords, and cut off the excess length; (3) Weld the steel round tube diagonal web members to the corresponding positions of the upper and lower chords; (4) Weld steel beam stiffeners on both sides of the web at the corresponding position of the steel beam below the steel round tube straight web member.

[0009] The beneficial effects of the present invention are as follows: The present invention is based on a new type of node and installation method for BIPV photovoltaic reinforcement. Its force transmission system is clear and can effectively transfer photovoltaic loads to the steel beam. The waterproof construction is convenient, the opening area of ​​the roof panel is reduced, and the installation and construction of waterproof measures are convenient. The on-site installation is fast and convenient, and it can be hinged to the upper and lower chords after welding. BRIEF DESCRIPTION OF THE DRAWINGS
