Description

Technical Field

[0001] The invention relates to the technical field of building coupling beam structure design, in particular to a prefabricated assembled coupling beam with a built-in damper and a construction method thereof. Background Art

[0002] A connecting beam refers to a beam that connects wall limbs and wall limbs, or wall limbs and frame columns in a shear wall structure and a frame-shear wall structure. It is generally located in the horizontal structure of a building. Its main function is to connect each wall limb or wall limb to the frame column under horizontal loads (such as wind loads, earthquakes, etc.) so that the entire structure can work together and enhance the integrity and seismic performance of the structure.

[0003] The characteristics of coupling beams are: first, the span is relatively small, usually connecting two adjacent vertical members with a small span; second, the force is complex, under the action of horizontal loads, the coupling beam will bear large shear forces and bending moments; especially under the action of earthquakes, the coupling beams often enter an elastic-plastic state, consuming energy through deformation to protect the main structure.

[0004] The connecting beam is an important component of the shear wall structure. It works together with the shear wall to resist horizontal loads. The shear wall provides support for the connecting beam, and the connecting beam connects the shear walls to form a whole.

[0005] In the frame-shear wall structure, the connecting beam connects the wall limbs and the frame columns, playing the role of transmitting horizontal forces. The frame columns provide certain constraints for the connecting beams, thereby enhancing the stability of the connecting beams.

[0006] However, the current coupling beam structure still has shortcomings in terms of energy absorption, fatigue resistance and coping with complex loads, and needs further improvement and optimization. Summary of the invention

[0050] S6. The prefabricated assembled coupling beam with built-in damper is fixedly connected to the column of the building as a whole:

[0051] Place the prefabricated assembled coupling beam with built-in damper at the location to be installed, drill holes at positions corresponding to the bolt fixing holes on the building columns and install anchor bolts, and use nuts to fix the end face connecting rings and anchor bolts;

[0052] The installation construction of a prefabricated assembled connecting beam with a built-in damper can be completed between the columns of the building.

[0053] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0054] 1. The coupling beam structure of the present invention is reasonably designed and has high-efficiency energy dissipation characteristics. Under the action of dynamic loads such as earthquakes and wind vibrations, the outer tube shell of the buffer structure and the multiple forward torsion buffer rods connected thereto, the inner tube shell of the buffer structure and the multiple reverse torsion buffer rods connected thereto can quickly and effectively consume energy, reduce the vibration amplitude of the coupling beam and the entire structure, reduce the structural response, and thus protect the main structure from serious damage;

[0055] 2. The present invention is easy to operate and has good deformation capacity. It can cope with various situations of compression, stretching, bending and torsion under dynamic loads such as earthquakes and wind vibrations. The coupling beam itself has the characteristic of being able to maintain a certain bearing capacity under large deformation conditions, adapting to the large displacement of the structure under extreme conditions such as earthquakes, avoiding premature damage, and providing guarantee for personnel evacuation and structural safety.

[0056] 3. The coupling beam of the present invention has reasonable stiffness, which is moderate, neither too large nor too small. Too large stiffness is not conducive to energy consumption, while too small stiffness may cause excessive deformation of the structure. Reasonable stiffness can work together with the overall structure to ensure the stability of the structure under normal use and play a good role in energy consumption and shock absorption when dynamic loads act.

[0057] 4. The coupling beam of the present invention is prefabricated and assembled, which is convenient for transportation and installation. The size and weight of the components are designed to facilitate flexible adjustment in actual foundation construction, meet the limitations of transportation vehicles and construction site lifting equipment, facilitate transportation from the prefabrication factory to the construction site, and can be installed efficiently, reducing the difficulty and time cost of on-site construction;

[0058] 5. The coupling beam of the present invention has high-precision prefabrication quality. During the prefabrication process in the factory, standardized production processes and strict quality control are used to ensure that the dimensions of each part of the coupling beam are accurate and the surface is flat, ensuring the smooth splicing of components at the construction site, improving the overall assembly quality of the structure, and reducing quality problems caused by construction errors;

[0059] 6. The coupling beam of the present invention has good anti-fatigue performance. The coupling beam and its built-in damper can withstand multiple repeated loads without fatigue damage. During long-term use, especially when frequently subjected to repeated loads such as wind vibration and small earthquakes, the safety and reliability of the structure can be well guaranteed.
