Background
With the progress of building science and technology, the structural seismic technology level is continuously improved, and in order to avoid serious influence of earthquake disasters on social development, the concept of function recovery is becoming the direction of future engineering seismic development. In 2011, Chinese scholars clearly define the concept of recoverable functional structure. How to design a structure which can not be damaged or only be damaged quickly in the earthquake becomes one of the important research directions for continuously developing engineering earthquake resistance.
Self-restoring rocking structures are one of the main forms of realization for recoverable functional structures, and in early rocking building structures, it was common practice to relax the constraints between the structure and the foundation. In addition, the structural design of relaxing the constraint between members, such as a post-tensioned prestressed prefabricated frame structure, is also developed by the scholars in Europe, Japan and China, the rotation of frame beams is allowed to enable the structure to swing through relaxing the beam-column node constraint, and the structure is self-restored through prestress.
The replaceable concept is applied to structural engineering in recent years, and is firstly applied to bridge engineering, and then better development is achieved in a steel structural system, so that the application and research in a concrete structural system are also effective at present. From a structural form, the structure with the replaceable member belongs to one of the recoverable functional structures. The strength of a part of the structure is weakened, or a ductile energy consumption component is arranged on the part, the weakened part or the energy consumption component is arranged to be a replaceable component, and the replaceable component is connected with the main structure through a device which is convenient to disassemble, namely the structural system with the replaceable component. Under the action of earthquake, the earthquake input energy is dissipated, the main body structure is protected from being damaged or only slightly damaged, and the structural function can be recovered only by replacing the energy consumption component after the earthquake action.
SUMMERY OF THE UTILITY MODEL
The utility model provides an assembled of external connecting piece of belt shakes and puts post system. Can be used in a self-resetting rocking structure.
The utility model adopts the technical proposal that:
an assembled swinging column system with an external connecting piece comprises an external connecting piece, an assembled swinging column body and a vibration isolation support; the assembled swing column is composed of concrete and a rib body; the external connecting piece connects the assembled swing column with the frame beam; a shock insulation support is arranged at the joint of the assembled swing column and the frame beam; the external connecting piece consists of an external rib body and an anchorage device.
A plurality of anchors are embedded in the assembled swinging cylinder; the assembled swinging column adopts a common reinforced concrete column or a combined structure column.
The utility model has the advantages that:
1. the utility model discloses utilize isolation bearing to connect the beam system and sway the cylinder, realize the column end power consumption mechanism, prevent the extrusion of column end concrete and the damage that causes.
2. The external connecting piece realizes the configuration of the external self-resetting rib body through the column end anchorage device, provides the self-resetting capability for the swinging column body on the premise of not changing the section areas of the column and the beam, and avoids the complicated construction process of the traditional swinging column body.
3. The external connecting piece is an independent component, can be disassembled and easily replaced after the earthquake, so that the use function of the swinging column system can be quickly recovered after the earthquake.
4. The shock insulation support is arranged at the node of the swing column and the beam system, and is deformed first in the swing process, so that the seismic action of the upper structure is reduced, the local damage of the concrete at the column end under the seismic action is prevented, and the shear-resistant bearing capacity of the node is improved through reasonable connection design.
5. The column end and the cross beam are connected by the external connecting piece, so that necessary self-resetting capability is provided for the swing column, and certain shearing-resistant bearing capacity is provided.
