Embodiment 1
[0031] Attached below figure 1 - attached Figure 4 The energy consumption nodes disclosed in this embodiment are further explained;
[0032] Refer to attached figure 1 As shown, a U-shaped steel-friction energy-dissipating node for an assembled external wall panel mainly includes a lower node 4, an upper node and an I-shaped steel beam 6. The lower node connects the upper external wall panel with the I-shaped steel beam, and the upper node connects the lower external wall panel with the I-shaped steel beam, which plays a role of shock absorption and energy consumption. Wherein the lower node is connected to the bottom of the upper external wall panel; the upper node is connected to the top of the lower external wall panel. The definition of upper node and lower node in this embodiment is: the upper end corresponding to a certain layer of external wall panels is an upper node, and the lower end corresponding to a certain layer of external wall panels is a lower node.
