Problems solved by technology

[0003] However, my country's prefabricated concrete frame structure started late, and its development is still immature. Since the beam-column members of the prefabricated concrete frame structure are not connected by cast-in-place for the first time, compared with ordinary cast-in-place structures,

Example Embodiment

[0025] Example 1

[0026] In this embodiment, the concrete column is a side column.

[0027] Such as Figure 1 to Figure 3 As shown, the plug-and-play anti-seismic energy dissipation device suitable for fabricated frame structures of the present invention includes a support base I1 embedded in a concrete foundation, a support base II2 embedded in a concrete column, and a connecting support base I and Energy consumption damping device 3 of support base II;

[0028] Support base I and support base II have the same structure, and both include parallel upper anchor plates 4 and lower anchor plates 5. The upper anchor plates and the lower anchor plates are connected by straight anchor ribs 6, and the upper anchor plates are provided with ear plates I7; The ear plate I includes two parallel ear plates, and the outer sides of the two ear plates are provided with stiffening ribs 8 to enhance the stability and torsion resistance of the ear plates. Since the diameter of the straight anchor ...

Example Embodiment

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that the concrete column is not a side column. In this case, the support base I in the concrete column must be connected to the support base II on both sides through an energy dissipation damping device. Two support bases I are pre-embedded in the concrete column to realize the connection with the support bases II on both sides. In order to simplify the construction steps, you can also combine the two support bases I into one, such as Image 6 As shown, the support base I includes three parallel anchor plates, which are connected by straight anchor ribs, the two outer anchor plates are welded with ear plates I, and the ear plates I and II are connected.

[0036] Others are the same as in Example 1.

Abstract

The invention relates to the field of building components, and discloses a plug-and-play anti-seismic energy dissipation device suitable for an assembled frame structure, which includes a support seat I pre-buried in a concrete foundation and a support seat II pre-buried in a concrete column And the energy dissipation damping device connecting the support base I and the support base II. The invention can provide greater lateral stiffness under earthquake action, and when the energy-dissipating damping device yields under tension or compression, it uses hysteretic characteristics to dissipate earthquake energy, and has a strong energy-dissipating capacity; all components are prefabricated in the factory, and the construction site Only simple assembly is required, the construction speed is fast, the industrialization level is high, and it is easy to replace after the earthquake, which conforms to the "plug and play" design concept.

Description

technical field [0001] The invention relates to the field of building components, in particular to a plug-and-play anti-seismic energy dissipation device suitable for an assembled frame structure. Background technique [0002] Prefabricated concrete frame structure refers to a structural system in which beams, columns and other components are assembled and spliced ​​on site. It has the obvious advantages of low construction cost, high construction efficiency, relatively stable quality of construction products, and "four savings and one environmental protection". It is an important direction for the development of construction technology in the future. [0003] However, my country's prefabricated concrete frame structure started late, and its development is still immature. Since the beam-column members of the prefabricated concrete frame structure are not connected by cast-in-place for the first time, compared with ordinary cast-in-place structures, the mechanical performance...
