Description

Assembled building shock attenuation connection structure for building Technical Field The invention relates to the technical field of building shock absorption, in particular to an assembled building shock absorption connecting structure for a building. Background The assembled building is formed by transferring a large amount of field operation in the traditional building mode to a factory, processing and manufacturing components and accessories (such as beams, columns, floors and various support brackets) for the building in the factory, transporting the components and accessories to a building construction site, and assembling and connecting the components and the accessories on the site. The construction mode has the advantages of high construction efficiency, short construction period and the like, and meets the development requirements of green buildings and building industrialization. At present, in the building process of an assembled structure, welding or bolts are adopted to rigidly connect the support upright posts and the cross bars, when the connecting mode faces dynamic loads such as wind vibration and earthquake, vibration energy is easy to accumulate at the connecting positions, so that welding seams are cracked, the bolts are loosened and even members are broken, and therefore, a damping connecting structure is required to be installed at the connecting points of the support to improve the shock resistance of the building. However, the conventional shock-absorbing connecting structure is generally composed of a damper, a spring, a bolt and other parts, and the damper always participates in structural stress in the use process, so that the integral rigidity of the support is low under normal use conditions (such as construction load, personnel operation and the like), the support is easy to shake, a stable operation platform cannot be provided for construction operation, and therefore construction quality and efficiency are seriously affected. Disclosure of Invention The invention aims to solve the problems that the whole rigidity of a bracket is low, the bracket is easy to shake and the construction operation is influenced because a damper always participates in stress when the traditional shock absorption connecting structure is used.
