Novel reinforced concrete structure beam-column joint and construction method thereof
The invention provides a novel reinforced concrete structure beam-column joint. The novel reinforced concrete structure beam-column joint comprises a beam-column joint core area and reinforced concrete ring beams, wherein the reinforced concrete ring beams are arranged on the periphery of the beam-column joint core area, the beam-column joint core area comprises main reinforcement penetrating through the joint core area in a frame column, stirrups, reinforcement stirrups, steel plate sleeves, concrete and the like, and the stirrups, the reinforcement stirrups, the steel plate sleeves, the concrete and the like are arranged in the core area. The stirrups are bound on the outside the main reinforcement, the steel plate sleeves sleeving the stirrups are supported on bottom reinforcement barsof a frame beam penetrating through the core area; steel plate strips are used for replacing part of the stirrups, reducing the spacing of the stirrups and improving structural measures; a space witha diameter of about 200 mm is freed up in the center of the joint core area, and an operation space is provided for steel bar binding and installation; meanwhile, insertion and extraction of a vibration rod are convenient, and compactness of the concrete by vibration is possible; the concrete in the joint core area in the enclosed areas of the steel plate sleeves can be poured at the same time with a lower column, and the problem of concrete pouring in the core area when the strength of column concrete is higher than that of a beam slab can be easily solved.
本发明提供一种新型钢筋混凝土结构梁柱节点，包括梁柱节点核心区和钢筋混凝土环梁，其中钢筋混凝土环梁设置在所述梁柱节点核心区周围。所述梁柱节点核心区包括框架柱中穿过节点核心区的主筋、及核心区内的箍筋、加强箍筋、钢板套、混凝土等，所述箍筋绑扎在主筋外，套在箍筋外的钢板套支于穿越核心区的框架梁底部钢筋之上；采取钢板带替代部分箍筋、缩小箍筋间距、完善构造措施等，在节点核心区中心腾出大约直径为200mm的空间，为钢筋绑扎与安装提供操作空间；同时便于振动棒的插拔，使混凝土受振密实成为可能；处在钢板套封闭区域内的节点核心区混凝土可与下柱同时浇筑,可轻松解决柱混凝土强度高于梁板时,核心区混凝土的浇筑难题。
