Description

Technical Field

[0001] This utility model relates to the field of connection device technology, specifically a seismic-resistant and reinforced steel-concrete composite structure wall connection device. Background Technology

[0002] The seismic-strengthened steel-concrete composite structure wall connection device is a key component used to improve the seismic performance of building structures. This device is primarily used between the steel-concrete composite structure and the wall, achieving a reliable connection through specific structural design. It is typically made of high-strength and tough steel, including the main components such as connecting steel plates and supports, and can be supplemented with auxiliary components such as reinforcing ribs, bolts, and shear keys as needed. Under seismic loading, this device effectively transfers the load on the wall to the steel-concrete composite structure, allowing them to work together. Utilizing the excellent compressive strength and energy dissipation characteristics of the steel-concrete composite structure, it restrains wall deformation, enhances the overall structural integrity, and reduces earthquake damage to buildings. It is widely applicable to upgrading the seismic resistance of new buildings and seismic strengthening and retrofitting projects for existing buildings.

[0003] Most existing reinforced steel-concrete composite wall connection devices are integrated designs. However, in practical applications, when faced with different building structures and varying seismic requirements, their strength cannot be adjusted as needed, which may lead to failure to meet strength requirements or waste of resources due to excessive strength. To address this, we propose a seismically reinforced steel-concrete composite wall connection device. Utility Model Content
