Connecting structure of frictional type damper assembling type frame joint and constructing method thereof

Abstract

Disclosed is a connecting structure of a frictional type damper assembling type frame joint. Prestress steel strands are arranged in steel strand embedded pipes of the structure, precast reinforced concrete beams are connected with precast reinforced concrete columns through the prestress steel strands, the seams between the beams and the columns are filled of high-strength grouting materials, and beam and column connecting joints are formed. Frictional type dampers are arranged at the positions of the beam and column connecting joints, and the connecting structure of the whole frictional type damper assembling type frame joint attached with prestress is formed. The constructing method comprises the steps that the precast reinforced concrete beams are aligned to the damper embedded pipes on the precast reinforced concrete columns; the steel strands are arranged in the steel strand embedded pipes of the precast reinforced concrete beams in a penetrating mode; the seams are filled with the high-strength grouting materials, and the whole beam and column joints are formed; frictional damper fixing screw rods are arranged in the damper embedded pipes in a penetrating mode to mount the frictional type dampers. According to the structure, the energy-dissipating capacity of the assembling type frame structure under the earthquake action can be effectively improved, effective connection of the columns and the beams is ensured, the earthquake energy can be effectively consumed, and the building structure is protected.

Description

technical field [0001] The invention relates to a connection structure of a friction damper assembled frame node and a construction method thereof, is a novel prefabricated frame structure node connection and energy consumption technology, and belongs to the field of anti-seismic technology of an assembled concrete frame structure in civil engineering. Background technique [0002] my country is an earthquake-prone country, and most areas are in seismic fortification areas. In actual engineering construction, prefabricated frame structures can reduce engineering costs, speed up construction, reduce resource consumption, and reduce environmental pollution. It is one of the development directions of my country's construction industry. Compared with cast-in-place reinforced concrete frame structures, the energy dissipation capacity of prefabricated reinforced concrete frame structure nodes is slightly insufficient, and the low seismic energy dissipation capacity of prefabricate...
