Damping energy dissipation assembling node of precast column and integrated precast beam panel, and construction method thereof

Abstract

The invention relates to a damping energy dissipation assembling node of a precast column and an integrated precast beam panel, and a construction method thereof. The assembling node comprises the integrated precast beam panel and the precast column, wherein the precast column comprises a lower precast column and an upper precast column; flaring steel pipes I are pre-embedded to the upper surfaceof the lower precast column; the integrated precast beam panel is arranged on the lower precast column and is pre-embedded with a damping steel pipe and multiple necking steel pipes; the upper precastcolumn is arranged on the integrated precast beam panel; a connecting steel pipe and multiple flaring steel pipe II are pre-embedded to the lower surface of the upper precast column; the free end ofthe connecting steel pipe extends into the damping steel pipe; the flaring steel pipes I and the flaring steel pipes II are coaxial in a one-to-one correspondence way and extend into two ends of the corresponding necking steel pipes; flaring parts are arranged at the free ends of the flaring steel pipes I and the flaring steel pipes II; necking parts are arranged at two ends of the necking steel pipes; the corresponding flaring parts of the flaring steel pipes I and the flaring steel pipes II are clamped into the necking parts so as to realize clamping; a connecting structural steel is also preserved on the upper surface of the lower precast column; the free end of the connecting structural steel penetrates through the damping steel pipe and extends into the connecting steel pipe.

Description

technical field [0001] The invention belongs to the technical field of fixed buildings, and in particular relates to a damping energy-dissipating assembly node of a prefabricated column and an integrated prefabricated beam slab and a construction method thereof. Background technique [0002] Prefabricated building is an energy-saving, environmentally friendly and efficient building form. Prefabricated concrete structures have the advantages of high economic benefits, less impact on construction by climatic conditions, easy guarantee of product quality, short construction time and less environmental pollution, and have become an important direction for the development of the construction industry. [0003] According to the damage simulation test of prefabricated buildings and the analysis of some actual damage sites, the main form of prefabricated building damage is the damage at the assembly nodes. Therefore, the seismic capacity of the assembly nodes determines the overall ...

Problems solved by technology

With the development of assembly technology, the existing technology can ensure the safety and reliability of the connection of assembly nodes, but there are still many aspects that need to be optimized in the form and method of prefabricated buildings, such as: 1. When the structural system is prefabricated and installed beams and slabs The system is basically separated, the beams are prefabricated first, and the slab surface is treated by post-casting. The integrity of the structural system is affected to a certain extent, which is not conducive to the play of the overall seismic performance of the structure; The assembly connection is complex, and the construction is relatively difficult, which is not conducive to the improvement of construction efficiency and construction quality; the stiffness, seismic performance, and energy dissipation capacity of the assembly nodes need to be improved; 3. The assembly method of the existing structural system still requires a lot of Temporary support system, installation and removal are time-consuming and labor-intensive, and construction efficiency is low
