Fabricated self-resetting concrete frame joint with efficient energy consumption and high robustness
The invention relates to the field of civil engineering fabricated structures, and discloses a fabricated self-resetting concrete frame joint with efficient energy consumption and high robustness. Comprising a prefabricated concrete column, a prefabricated concrete beam, a steel beam anchoring device, an efficient energy dissipation device, an energy dissipation device support, beam end angle steel, an energy dissipation device connecting plate, a fixing steel plate, high-strength bolts and unbonded prestressed tendons. According to the assembly type self-resetting concrete frame joint with efficient energy consumption and high robustness, the unbonded prestressed tendons penetrate through the prefabricated concrete beams and are anchored on the steel beam anchoring devices located at the beam ends, and when the joint rotates relatively due to disasters such as earthquakes, the prefabricated concrete beams are separated from the steel beam anchoring devices; the formed opening angle can avoid tensile yield of the longitudinal bars in the beam; in addition, the steel beam anchoring device is fixed to the prefabricated concrete column through high-strength bolts, the prefabricated concrete column and the joint core area are restrained and protected, and damage to the joint core area is avoided.
本发明涉及土木工程装配式结构领域，且公开了兼具高效耗能及高鲁棒性的装配式自复位混凝土框架节点，包括预制混凝土柱、预制混凝土梁、钢梁锚固装置、高效耗能装置、耗能装置支座、梁端角钢、耗能装置连接板、固定钢板、高强螺栓以及无粘结预应力筋，该兼具高效耗能及高鲁棒性的装配式自复位混凝土框架节点将无粘结预应力筋贯穿预制混凝土梁，并锚固在位于梁端的钢梁锚固装置上，节点在地震等灾害引起相对转动时，预制混凝土梁与钢梁锚固装置分离，所形成的张开角可以避免梁内纵筋的受拉屈服；此外，钢梁锚固装置通过高强螺栓与预制混凝土柱固定，对预制混凝土柱及节点核心区形成约束和保护，避免了节点核心区的破坏。
