The invention discloses a fabricated concrete frame beam-column joint with double longitudinal beams, which is characterized in that the joint comprises a prefabricated frame beam-column joint core area, a prefabricated reinforced concrete frame lower column, a prefabricated reinforced concrete frame upper column, the prefabricated reinforced concrete frame double longitudinal beams, prefabricated reinforced concrete frame cross beams and connecting plates, a concrete protection layer; wherein the prefabricated frame beam-column joint core area is spliced with the prefabricated reinforced concrete frame lower column and the prefabricated reinforced concrete frame upper column through steel columns, and the prefabricated frame beam-column joint core area is spliced with the prefabricated reinforced concrete frame double longitudinal beams and the prefabricated reinforced concrete frame cross beams through steel beams; and after splicing is completed, a concrete protection layer is poured for protection. The prefabricated concrete frame beam-column joint with the double longitudinal beams is suitable for a power plant main workshop, and meanwhile the problems that a core area of an existing prefabricated concrete frame structure joint is large in pouring difficulty, connection quality is difficult to control, and the construction period is long can be effectively solved.

本发明公开了一种带双纵梁的装配式混凝土框架梁柱节点，其特征在于：所述节点包括：预制框架梁柱节点核芯区、预制钢筋混凝土框架下柱、预制钢筋混凝土框架上柱、预制钢筋混凝土框架双纵梁、预制钢筋混凝土框架横梁，连接板，混凝土保护层；其中，预制框架梁柱节点核芯区与预制钢筋混凝土框架下柱、预制钢筋混凝土框架上柱之间采用钢柱拼接，与预制钢筋混凝土框架双纵梁、预制钢筋混凝土框架横梁之间采用钢梁拼接；拼接完成后浇筑混凝土保护层保护。本发明适用于电厂主厂房带双纵梁的装配式混凝土框架梁柱节点，同时本发明可以有效解决目前预制混凝土框架结构节点核芯区浇筑难度大、连接质量难控制、施工工期长等问题。
