Problems solved by technology

As the key part of the connection, the wall joints directly affect the stability of the main structure, overall stiffness, seismic performance and bearing capacity. The traditional connection method may cause damage to the joints under earthquake action, and even Cause the external wall panel to break away from the main structure
[0003] At present, in the existing implementation schemes, the U-shaped energy-dissipating nodes of aerated concrete, and the external wall panels use U-shaped steel plates and springs to dissipate energy; Less internal deformation and therefore less energy dissipation

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.

Abstract

The invention discloses a U-shaped steel-friction energy-dissipating node and an outer wall system for an assembled external wall panel, including an upper node, the upper node includes a first steel plate, the first steel plate is U-shaped, and the first steel plate includes Two opposite straight plates, the ends of the two straight plates are connected by arc-shaped plates, a second steel plate is connected between the tops of the two straight plates, and a third steel plate is arranged on the top of the second steel plate; a lower node is arranged above the first steel plate, and the second There is an I-shaped steel beam connected between the first steel plate and the lower node, the second steel plate has an oblong hole, the third steel plate has a first bolt hole, the lower flange of the I-shaped steel beam has a hole, and the first connecting piece passes through The overlong round hole, the first bolt hole and the hole connect the second steel plate, the third steel plate and the I-shaped steel beam.

Description

technical field [0001] The disclosure belongs to the field of construction, and in particular relates to a U-shaped steel-friction energy-dissipating node and an exterior wall system for an assembled exterior wall panel. Background technique [0002] Prefabricated buildings are of great significance in the process of building industrialization. Prefabricated buildings can not only improve project quality, save labor, but also effectively achieve energy conservation and environmental protection. As the key part of the connection, the wall joints directly affect the stability of the main structure, overall stiffness, seismic performance and bearing capacity. The traditional connection method may cause damage to the joints under earthquake action, and even Cause the external wall panel to break away from the main structure. [0003] At present, in the existing implementation schemes, the U-shaped energy-dissipating nodes of aerated concrete, and the external wall panels use U-...
