Embodiment 1

[0030] The invention provides a new type of prefabricated concrete structure beam-column joint, such as figure 1 shown. The beam-column joint of the new prefabricated concrete structure includes a prefabricated column 1, a prefabricated beam 2 and an overlapping beam 3, and a beam-column connection core area 11 composed of a prefabricated column 1 and a prefabricated beam 2 connection, a prefabricated column and a prefabricated column The column-column connection area 12 formed by the connection part, and the beam-beam connection area 13 composed of the prefabricated beam and the lap beam connection part, the beam-column connection core area 11 of the prefabricated column 1 and the prefabricated beam 2 is integrally prefabricated . The column-to-column connection area 12 is connected by planting bars and fixed by a curing agent. Preferably, the curing agent is a fast-hardening structural adhesive. The column-column connection area 12 includes a reinforcement hole 121 arrange...

Abstract

The invention discloses a novel fabricated concrete structure beam-column joint. The novel fabricated concrete structure beam-column joint comprises a prefabricated column, prefabricated beams and lapjoint beams, column-column connecting areas are connected by adopting embedded steel bars and are fixed by adopting a curing agent, and each column-column connecting area comprises embedded steel barholes formed in the upper end of the column-column connecting area, lap joint steel bars arranged at the lower end of the column-column connecting area and load-bearing steel bars arranged in the column-column connecting area; the embedded steel bar holes and the lap joint steel bars are arranged in a one-to-one corresponding mode, and the hole diameter of the embedded steel bar holes is slightlylarger than that of the lap joint steel bars; and the prefabricated beams and the lap joint ends of the lap joint beams are provided with notch beams correspondingly in a matched mode to form rabbets, pre-embedded angle steel is distributed at the edges of the notch beams, beam-beam connecting areas are connected through the rabbets and welded and fixed, and the pre-embedded angle steel is distributed at the edges of the notch beams. The novel fabricated concrete structure beam-column joint good in integrity and high in universality, the column-column connecting areas and the beam-beam connecting areas are simple in structure, meanwhile, the disadvantage that a previous beam-column connecting place is complex in stress and prone to being damaged.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structural components, and in particular relates to a novel assembled concrete structure beam-column node. Background technique [0002] At present, most of the buildings in our country are constructed by cast-in-place reinforced concrete technology. With the promotion and application of prefabricated concrete technology, in order to ensure that the structural performance of prefabricated concrete structures is not lower than that of cast-in-place concrete structures, my country has also formulated corresponding technical regulations for concrete structures, including from structural design to component prefabrication and on-site construction. , the basic idea is to rationally split the cast-in-situ concrete structure, factory prefabricated components, and on-site assembly. The split is beneficial to factory prefabrication and on-site assembly, and the assembled structure ...
