BRIDGE FAIRING Russian patent published in 2024 - IPC E01D19/00 E01D1/00 

FIELD: construction.

SUBSTANCE: invention relates to construction of bridge crossings and overpasses, namely to devices, which provide reduction of aerodynamic wind loads and reduction of amplitude of oscillations of continuous spans of bridges. Bridge fairing (1) consists of longitudinal support structure (2) made with possibility of installation on bridge span (3), and fairing panels (8, 11) mounted on it. Support structure (2) comprises at least two codirectional longitudinal profiles (5), installed at different height of bridge span (3) with possibility of adjustment and fixation of its position in height and overhang by means of at least two rows of attachment brackets (6). Codirectional longitudinal profiles (5) are made with possibility of serial connection. According to the first version of the invention, panels (11) of the fairing are connected to each other in series to form a single surface, and are also made self-supporting and contain at least two rows of support parts (12, 13), by means of which panels (11) of fairing are installed on codirectional longitudinal profiles (5). According to the second version of the invention, panels (8) of the fairing are installed on shaped frames (4) from vertical and horizontal profiles (14, 15), which contain at least two rows of support parts (12, 13), by means of which panels (8) of fairing are installed on codirectional longitudinal profiles (5). Shaped frames (4) are connected in series so that panels (8) of the fairing form a single surface.

EFFECT: simplifying the installation of bridge fairing elements, reducing aerodynamic wind loads and reducing the amplitude of vibrations of bridge spans.
