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, the mechanical performance of joints are weakened, which directly leads to the lack of integrity of the building structure
Under the action of earthquakes, the stress on the nodes is complex and changeable, and they are prone to damage, so it is temporarily impossible to carry out large-scale promotion

Embodiment 1

[0026] In this embodiment, the concrete columns are side columns.

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

[0028] The support seat I and the support seat II have the same structure, both of which include parallel upper anchor plate 4 and lower anchor plate 5, the upper anchor plate and the lower anchor plate are connected by straight anchor ribs 6, and the upper anchor plate is provided with ear plate I7; The lug I includes two parallel lugs, and the outer sides of the two lugs are provided with stiffening ribs 8 for enhancing the stability and torsional performance of the lugs. Since the diameter of the straight anchor bar is greater ...

Embodiment 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 seat I in the concrete column should be connected to the support seat II on both sides through the energy dissipation damping device. Two supporting seats I are pre-embedded in the concrete column to realize the connection with the supporting seats II on both sides. In order to simplify the construction steps, the two support bases I can also be combined into one, such as Image 6 As shown, the support base I includes three parallel anchor plates, the anchor plates are connected by straight anchor bars, and the two outer anchor plates are welded with ear plates I, and the ear plate I is connected with the ear plate II.

[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...
