U-shaped steel-friction energy dissipation joint for fabricated external hanging wallboard and outer wall system

Abstract

The invention discloses a U-shaped steel-friction energy dissipation joint for a fabricated external hanging wallboard and an outer wall system. The U-shaped steel-friction energy dissipation joint for the fabricated external hanging wallboard comprises an upper joint body, the upper joint body comprises a first steel plate, the first steel plate is in a U shape, the first steel plate comprises two straight plates which are oppositely arranged, the end parts of the two straight plates are connected through an arc-shaped plate, a second steel plate is connected between the tops of the two straight plates, a third steel plate is arranged on the top of the second steel plate, a lower joint is arranged on the first steel plate, an I-shaped steel beam is connected between the first steel plateand the lower joint, a long round hole is formed in the second steel plate, a first bolt hole is formed in the third steel plate, a hole is formed in a lower flange of the I-shaped steel beam, and a first connecting piece penetrates through the long round hole, the first bolt hole and the hole to be connected with 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-...

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
