技术领域 technical field

本实用新型涉及一种抗剪钢管混凝土梁柱节点连接结构,属于建筑结构工程技术领域。 The utility model relates to a shear-resistant steel pipe concrete beam-column node connection structure, which belongs to the technical field of building structure engineering.

背景技术 Background technique

钢管混凝土结构是在钢管中填充混凝土构成,它是在型钢混凝土和配螺旋箍筋的钢筋混凝土的基础上发展和演变而来的。钢管的存在能够防止混凝土过早开裂,混凝土的存在能够防止钢管的过早屈曲,二者共同工作能充分发挥钢材受拉性能高和混凝土受压性能好的优点,因此具有承载力高、塑性和韧性好、抗震性能好、经济效益显著和施工环保等许多优点,在高层及超高层建筑中具有很好的应用前景,现已受到国内外工程领域的普遍重视。 The steel pipe concrete structure is composed of steel pipes filled with concrete. It is developed and evolved on the basis of steel concrete and reinforced concrete with spiral stirrups. The existence of steel pipes can prevent premature cracking of concrete, and the existence of concrete can prevent premature buckling of steel pipes. Working together, the two can give full play to the advantages of high tensile properties of steel and good compressive properties of concrete, so they have high bearing capacity, plasticity and It has many advantages such as good toughness, good seismic performance, significant economic benefits, and construction environmental protection. It has a good application prospect in high-rise and super high-rise buildings, and has been widely valued by domestic and foreign engineering fields.

At present, the most commonly used joints between concrete filled steel tube columns and beams are different in performance due to different connection methods. The main joint forms are outer rib ring plate type, inner diaphragm type and diaphragm through type. In these nodes, the force of the steel beam web cannot be effectively transmitted through the nodes, especially the connection between the column and the beam, which is damaged due to the insufficient shear bearing capacity of the nodes under the action of a large earthquake load, which makes the whole The concrete-filled steel tube joints lose their bearing capacity and fail.
