Hyperbolic glass curtain wall station-entering awning and construction method

The invention relates to a hyperbolic glass curtain wall station-entering awning and a construction method, the awning comprises trapezoidal main keels, arc-shaped secondary keels, hyperbolic glass and aluminum plate structures, welding hand holes and grooves are reserved in the joints of the trapezoidal main keels and the arc-shaped secondary keels, the multiple trapezoidal main keels are arranged side by side at intervals, and the heights of the trapezoidal main keels are sequentially reduced backwards from the inlet end of the awning; the arc-shaped secondary keels are arranged between the adjacent trapezoidal main keels and are fixedly connected with the trapezoidal main keels through the grooves, and the cross sections of the arc-shaped secondary keels are T-shaped; the hyperbolic glass is mounted between the trapezoidal main keel and the arc-shaped secondary keel; and the aluminum plate structure is arranged above the inlet end of the awning. According to the method, the trapezoidal main keels and the a
