technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, in particular to a construction method for a connection node of an assembled energy dissipation pier. Background technique [0002] As green buildings and industrialized buildings become the future trend, prefabricated buildings will gradually develop, but prefabricated buildings will inevitably be subjected to external dynamic loads such as earthquakes during use, and are used as external parts of buildings. When the dynamic load reaches a certain intensity, the building will generate strong vibration, which not only seriously affects the normal use function of the building, but also may threaten the safety of the building, causing catastrophic consequences of building damage and collapse.

Problems solved by technology

[0002] As green buildings and industrialized buildings become the future trend, prefabricated buildings will gradually develop, but prefabricated buildings will inevitably be subjected to external dynamic loads such as earthquakes during use, and are used as external parts of buildings. When the dynamic load reaches a certain intensity, the building will generate strong vibration, which not only seriously affects the normal use function of the building, but also may threaten the safety of the building, causing catastrophic consequences of building damage and collapse. The performance is weaker than the seismic performance of cast-in-place structures, which limits the development of prefabricated buildings. Therefore, it is necessary to use energy dissipation and shock absorption technology to solve the current problems of prefabricated buildings.

At present, the energy-dissipating pier is usually directly hoisted to the site for fabrication and construction, but the cast-in-place energy-dissipating pier needs to go through steps such as binding the steel cage, pouring and curing the concrete to the design strength before installing the damper, which takes time. It is longer and the installation efficiency is low, which affects the further promotion of energy dissipation and shock absorption technology, and the height of the pier-type support is fixed and cannot be adjusted. In order to ensure the installation accuracy of the pier-type support, it is necessary to control the processing error of the pier-type support to avoid The pier support is too high or too low, which affects the construction period
