Embodiment 1

[0061] Such as Figure 1-9 As shown in the present invention, a prefabricated intelligent node with particle damping chamber energy consumption includes a core steel skeleton 1, an outsourcing fully assembled steel pipe column 2, a fully assembled annular beam-column connection assembly, and structural health detection System and particle damping chamber 17, the core steel skeleton is located in the outsourcing fully assembled steel pipe column and concentric with the outsourcing fully assembled steel pipe column, the core steel skeleton includes a circular hollow steel skeleton 8 and four outstretched steel plate wings 7, and the outsourcing fully assembled The fully assembled circular beam-column connection assembly includes 4 pairs of arc-shaped connection tiles and 4 beam-column core connectors 3, and the 4 pairs of arc-shaped connection tiles pass through each other. Bolt connection, jointly spliced ​​into a cylindrical outer reinforcement ring, the arc-shaped connection ...

Embodiment 2

[0068] Such as Figure 10-11 As shown, the present invention also includes a structural health detection system. The structural health detection system includes a main line, a wire, an FBG intelligent sensing element 16, a processor 22, a long-life power supply 23 and a wireless data transmitter 24. The structural health detection system is located at On the main line pipe 11 inside the circular hollow steel frame of the core steel frame, the annular data integration block 12 includes a processor, a wireless data transmitter and a long-life power supply, which are tightly packaged outside the main line pipe, and the main line pipe is wrapped with wires 13 and wires. The connected main line is connected to the annular data integrated block through the opening on the main line pipe. The hollow steel frame is provided with a wire hole for the wire to pass through and connect the FBG intelligent sensing element with the processor. The FBG intelligent sensing element and the corresp...

Embodiment 3

[0073] The structural health detection system also includes strain gauges attached to the inner wall of the steel pipe, and the strain gauges are connected with the processor in the annular data integration block through wires. The strain gauge can collect the information in the hollow steel pipe and transmit it to the annular data integrated block through the wire, and transmit it to the outside world through the wireless data transmitter.

[0074] Other technical characteristics are the same as embodiment 2.

Abstract

The invention relates to a fabricated intelligent joint with particle damping storehouse energy dissipation and an installing method, and belongs to the technical field of structural engineering. Thefabricated intelligent joint comprises a core steel frame, an exteriorly-wrapping full fabricated steel pipe column, a full fabricated annular beam column connection assembly, a structural health detection system and a particle damping storehouse, wherein the core steel frame is located in the exteriorly-wrapping full fabricated steel pipe column and concentric with the exteriorly-wrapping full fabricated steel pipe column, the core steel frame comprises a circular hollow steel rib and a plurality of overhanging steel plate wings, the exteriorly-wrapping full fabricated steel pipe column is formed by splicing a plurality of arc-shaped steel pipe column slices, the particle damping storehouse and pouring concrete are arranged in space between the exteriorly-wrapping full fabricated steel pipe column and the circular hollow steel rib of the core steel frame; and the particle damping storehouse internally contains a large amount of rubber spherical particles. The fabricated intelligent joint with the particle damping storehouse energy dissipation and the installing method have the advantages that the particle damping storehouse is applied to the fabricated steel structure joint, the energy dissipation effect is excellent, and the joint has an excellent anti-seismic property.

Description

technical field [0001] The invention relates to a prefabricated intelligent node with particle damping chamber for energy consumption and an installation method, belonging to the technical field of structural engineering. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for living conditions are getting higher and higher. From "living in a house" to "living in a good house", living space is not only required, but also spacious, comfortable and safe. . This puts forward higher requirements for housing construction technology. In recent years, with the development of construction industrialization, various new construction technologies have emerged one after another. The prefabricated steel structure construction technology has accumulated a lot in the years of development. Prefabricated steel structure buildings are widely used due to their advantages such as convenient construction, gr...
