Description
技术领域technical field
本发明属于建筑工程领域，具体涉及建筑结构技术，尤其涉及H型钢梁与矩形钢管混凝土柱的连接节点及制作方法。The invention belongs to the field of building engineering, and in particular relates to building structure technology, in particular to a connection node between an H-shaped steel beam and a rectangular steel pipe concrete column and a manufacturing method.
背景技术Background technique
随着建筑结构的发展，钢-混凝土组合结构的研究和应用得到迅速展开，钢管混凝土柱结构是在钢管中填充混凝土构成的，钢管的存在能够约束核心混凝土，防止核心混凝土在受力过程中过早开裂；核心混凝土的存在能够防止钢管的过早屈曲，二者协同作用能够充分发挥钢材受拉性能高和核心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。With the development of building structures, the research and application of steel-concrete composite structures has been rapidly developed. The steel pipe concrete column structure is composed of steel pipes filled with concrete. The existence of steel pipes can restrain the core concrete and prevent the core concrete from being overstressed. Early cracking; the existence of core concrete can prevent premature buckling of steel pipes, and the synergistic effect of the two can give full play to the advantages of high tensile performance of steel and good compression performance of core concrete, so it has high bearing capacity, good plasticity and toughness, and seismic performance Good, significant economic benefits and construction environmental protection and many other advantages.
矩形钢管混凝土柱既有塑性变形能力强、延性好、抗震性能优良等特性，而且更具有抗弯刚度大、节点连接方便的优点。矩形钢管混凝土柱与钢梁形成的框架结构体系，因平面布置灵活、结构简单、构件易于标准化、施工速度快、造价低等特点，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。Rectangular CFST columns not only have the characteristics of strong plastic deformation capacity, good ductility, and excellent seismic performance, but also have the advantages of high bending stiffness and convenient node connection. The frame structure system formed by rectangular steel tube concrete columns and steel beams has good application prospects in high-rise and super high-rise buildings due to its flexible layout, simple structure, easy standardization of components, fast construction speed, and low cost. It is generally valued by the engineering field at home and abroad.
在矩形钢管混凝土柱与钢梁形成的框架结构体系中，H型钢梁与矩形钢管混凝土柱形成的框架体系应用普遍。H型钢梁与矩形钢管混凝土柱的连接节点，根据连接节点的布置，主要分为：内隔板式，外环板式节点以及隔板贯通式连接节点三大类。其中，内隔板式节点是将节点的传力内隔板构件设在矩形钢管内部，加劲板尺寸较小，钢管柱外侧没有加劲板，方便幕墙安装，适用于大尺寸框架柱，且用钢量较外环节点有一定程度减小。H型钢梁的内力通过内隔板传递给钢管混凝土框架柱，上、下翼缘主要传递弯矩，腹板主要传递剪力。钢梁翼缘传来的拉力作用主要由内隔板承担，钢梁翼缘传来的压力主要由钢管内部的核心混凝土承担，受力形式合理，是普遍采用的一种节点形式。In the frame structure system formed by rectangular concrete-filled steel tube columns and steel beams, the frame system formed by H-shaped steel beams and rectangular steel tube concrete columns is widely used. The connection nodes between H-shaped steel beams and rectangular steel pipe concrete columns are mainly divided into three categories according to the layout of the connection nodes: inner diaphragm type, outer ring plate type joints and diaphragm through-type connection nodes. Among them, the inner diaphragm type joint is to set the force transmission inner diaphragm member of the joint inside the rectangular steel pipe, the size of the stiffening plate is small, and there is no stiffening plate outside the steel pipe column, which is convenient for curtain wall installation. It is suitable for large-sized frame columns, and steel The amount is reduced to a certain extent compared with the outer ring nodes. The internal force of the H-shaped steel beam is transmitted to the CFST frame column through the inner diaphragm, the upper and lower flanges mainly transmit the bending moment, and the web mainly transmits the shear force. The tension from the flange of the steel beam is mainly borne by the inner diaphragm, and the pressure from the flange of the steel beam is mainly borne by the core concrete inside the steel pipe. The form of force is reasonable, and it is a commonly used joint form.
由于矩形钢管对核心混凝土的约束作用不如圆钢管显著，且内部核心混凝土受到的约束不均匀，因此矩形钢管混凝土柱对浇筑核心混凝土质量要求较高。而由于受管柱边长的限制，现有的中部开孔的内隔板式连接节点，使得核心混凝土浇筑困难、振捣不方便，对核心混凝土浇筑的密实性及对核心混凝土的约束均造成较大影响，从而影响矩形钢管混凝土柱的整体受力性能。Since the confinement effect of rectangular steel pipes on the core concrete is not as significant as that of circular steel pipes, and the internal core concrete is not uniformly restrained, the rectangular concrete filled steel pipe columns have higher requirements on the quality of poured core concrete. However, due to the limitation of the side length of the pipe column, the existing inner diaphragm connection node with a hole in the middle makes it difficult to pour the core concrete and inconvenient to vibrate, which affects the compactness of the core concrete pouring and the constraints on the core concrete. Large impact, thus affecting the overall mechanical performance of the rectangular concrete filled steel tube column.
现有的内隔板式矩形钢管混凝土柱的制作方法，内隔板通常采用“熔化嘴电渣焊”方法与矩形钢管柱连接，施工复杂而且成本较高。In the existing manufacturing method of the inner partition type rectangular steel tube concrete column, the inner partition is usually connected with the rectangular steel tube column by the "melting nozzle electroslag welding" method, the construction is complicated and the cost is high.
因此工程实践中需要提供一种施工便捷、能有效提高矩形钢管柱内核心混凝土浇筑密实度且综合成本低的内隔板连接节点，能大大提高H型钢梁与矩形钢管混凝土柱组成的框架结构的受力性能和整体性。Therefore, in engineering practice, it is necessary to provide an inner diaphragm connection node that is convenient for construction, can effectively improve the pouring density of the core concrete in the rectangular steel pipe column, and has a low overall cost. It can greatly improve the frame structure composed of H-shaped steel beams and rectangular steel pipe concrete columns. force performance and integrity.
