Description

蜂窝状连接钢板-双肢钢管混凝土组合柱Honeycomb connected steel plate-concrete steel tube composite column with double legs

技术领域technical field

本实用新型涉及一种新型建筑结构技术领域,具体涉及一种蜂窝状连接钢板-双肢钢管混凝土组合柱。The utility model relates to the technical field of a novel building structure, in particular to a honeycomb connecting steel plate-double-leg steel pipe concrete composite column.

背景技术Background technique

近年来,国内钢和钢材的产量、品种、规格大幅度提升,钢结构的设计、制作、安装水平更是有了大幅度提高,钢结构在国内获得超常规发展。In recent years, the output, variety, and specifications of domestic steel and steel products have been greatly improved, and the design, manufacture, and installation of steel structures have been greatly improved. Steel structures have achieved extraordinary development in China.

钢筋混凝土柱由于存在自重大、抗裂性差等缺点,使得其难以满足承载力及耐久性等要求,从而限制了其适用范围;而钢柱具有强度高、自重轻、抗震性能好、变形能力强、施工周期短、良好且丰富的建筑艺术表现能力等特点,受到建筑师们的普遍青睐,在传统冶金工业厂房、高层和超高层以及大跨度结构的多年实践中,钢柱的突出优势与作用几乎无可替代。Due to the shortcomings of reinforced concrete columns such as heavy weight and poor crack resistance, it is difficult to meet the requirements of bearing capacity and durability, thus limiting its scope of application; while steel columns have high strength, light weight, good seismic performance, and strong deformation capacity. , short construction period, good and rich architectural artistic expression ability, etc., are generally favored by architects. In the practice of traditional metallurgical industrial plants, high-rise and super high-rise and long-span structures for many years, the outstanding advantages and functions of steel columns Almost irreplaceable.

钢柱按其截面形式可分为实腹式和格构式两大类。相对而言,实腹式柱构造简单,与其他构件连接也较为方便。但是,随着多高层建筑、大跨度结构、重型厂房的发展,建筑层数逐渐增多,上部荷载增加,必然导致钢柱截面尺寸增大,从而增加钢材耗量,提高了工程的综合造价。此时,为了节约钢材,传统方法是,选择格构式钢柱。然而,格构式钢柱截面是由单肢经缀材连接组合而成,制作施工相对繁琐,连接工作量偏大,而且虚轴的剪切变形较大,将会造成一定的附加挠曲,将会降低其工作性能;特别是虚、实轴的稳定性能差别较大,导致其材料不能充分发挥,也必然会增加工程的综合造价;而且,当柱身某处受有较大的水平集中力作用时,为避免柱肢受弯,还需要在该处设置横隔,会增加钢材耗量与施工难度,降低施工速度,增加施工工期,从而进一步增加工程的综合造价。当然,也可考虑选择蜂窝状腹板的箱型钢柱。然而,在实际工程中,为了不致过多削弱钢柱的抗剪能力,蜂窝状腹板的箱型钢柱截面的“扩张比”会受到一定的限制。在此情况下,特别是对于弯矩较大的压弯柱而言,其翼缘可能提前丧失其承载力,使其不能满足工程需要。此时,如何以较为经济的方式提高其单肢承载力,是解决该问题的关键所在。Steel columns can be divided into two categories: solid-web type and lattice type according to their cross-sectional forms. Relatively speaking, the solid-web column has a simple structure and is more convenient to connect with other components. However, with the development of multi-high-rise buildings, long-span structures, and heavy-duty factory buildings, the number of building floors gradually increases, and the upper load increases, which will inevitably lead to an increase in the cross-sectional size of steel columns, thereby increasing steel consumption and increasing the overall cost of the project. At this time, in order to save steel, the traditional method is to choose lattice steel columns. However, the cross-section of the lattice steel column is composed of single limbs connected by embroidered materials. The construction is relatively cumbersome, the workload of the connection is too large, and the shear deformation of the imaginary axis is relatively large, which will cause certain additional deflection. It will reduce its working performance; especially the difference between the stability of the virtual and real shafts is large, resulting in the inability of its materials to be fully utilized, and it will inevitably increase the overall cost of the project; When the force acts, in order to avoid the bending of the column limb, it is necessary to set a diaphragm at this place, which will increase the steel consumption and construction difficulty, reduce the construction speed, increase the construction period, and further increase the comprehensive cost of the project. Of course, box-shaped steel columns with honeycomb webs can also be considered. However, in actual engineering, in order not to weaken the shear capacity of the steel column too much, the "expansion ratio" of the box-shaped steel column section of the honeycomb web will be limited to a certain extent. In this case, especially for the bending column with a large bending moment, its flange may lose its bearing capacity in advance, so that it cannot meet the engineering needs. At this time, how to increase the bearing capacity of its single limb in a more economical way is the key to solving this problem.

实用新型内容Utility model content

本实用新型的目的在于克服现有技术的不足,提供一种蜂窝状连接钢板-双肢钢管混凝土组合柱。The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a honeycomb connected steel plate-double-legged steel pipe concrete composite column.

本实用新型采用的技术方案为:一种蜂窝状连接钢板-双肢钢管混凝土组合柱,包括钢管混凝土肢件一、钢管混凝土肢件二、钢质连接板一和钢质连接板二,所述钢管混凝土肢件一和钢管混凝土肢件二的两端分别通过钢质连接板一和钢质连接板二连接,形成双肢钢柱,钢质连接板一和钢质连接板二为中间开孔的蜂窝状连接板,钢质连接板一和钢质连接板二分别由两块边缘带缺口的形状相同钢板组成,这两块钢板通过对接焊缝焊接形成蜂窝状连接板。The technical solution adopted by the utility model is: a honeycomb-shaped connecting steel plate-concrete steel tube composite column with two legs, including a steel tube concrete leg part one, a steel tube concrete leg part two, a steel connecting plate one and a steel connecting plate two, the The two ends of concrete-filled steel pipe limb 1 and steel pipe concrete limb 2 are respectively connected by steel connecting plate 1 and steel connecting plate 2 to form double-leg steel columns, and steel connecting plate 1 and steel connecting plate 2 are openings in the middle The honeycomb connection plate, the steel connection plate 1 and the steel connection plate 2 are respectively composed of two steel plates with the same shape with notches on the edges, and the two steel plates are welded by butt welds to form a honeycomb connection plate.

作为优选,所述钢管混凝土肢件一和钢管混凝土肢件二为槽钢、钢管、工字钢或钢板。Preferably, the first and second concrete-filled steel pipe concrete limbs are channel steel, steel pipe, I-beam or steel plate.

作为优选,所述钢质连接板一和钢质连接板二的开孔形式为圆形、椭圆形、方形、长方形、六边形或八边形。Preferably, the openings of the first steel connecting plate and the second steel connecting plate are circular, oval, square, rectangular, hexagonal or octagonal.

对于格构式钢柱,两肢件主要承受轴力和弯矩,连接两肢的缀材主要抵抗水平剪力。因此,如何以较为经济的方式提高其单肢承载力,并如何减小其对虚轴的剪切变形,提高其抗剪承载力,改善其受力性能,使虚、实轴的稳定性能充分接近,使两主轴方向的材料都能得到充分发挥,以降低钢材用量,减少工程的综合造价,成为人们关注的焦点。对此,本实用新型用蜂窝状钢板作为连接板代替传统格构钢柱的缀材,将传统格构钢柱的钢肢件用钢管混凝土替换,并将两者焊接而构成一种蜂窝状连接钢板-双肢钢管混凝土组合柱。具体形成方式为:先在腹板所用钢板上按预定的折线或曲线进行切割,错开半个波,使波峰对波峰,用对接焊缝焊接形成蜂窝状连接板,然后与钢管混凝土单肢的钢管焊接,最后向钢管中浇注混凝土组合而成。For lattice steel columns, the two limbs mainly bear the axial force and bending moment, and the materials connecting the two limbs mainly resist the horizontal shear force. Therefore, how to increase its single-limb bearing capacity in a more economical way, and how to reduce its shear deformation on the virtual axis, increase its shear bearing capacity, improve its mechanical performance, and make the stability of the virtual and real axes fully Close, so that the materials in the direction of the two main axes can be fully utilized, so as to reduce the amount of steel and reduce the overall cost of the project, which has become the focus of attention. In this regard, the utility model uses honeycomb steel plates as connecting plates to replace the decorative materials of traditional lattice steel columns, replaces the steel limbs of traditional lattice steel columns with steel pipe concrete, and welds the two to form a honeycomb connection Steel plate-concrete filled steel tube composite column with double legs. The specific formation method is as follows: first cut the steel plate used for the web according to the predetermined fold line or curve, stagger half of the wave, make the wave crest face the wave peak, weld the honeycomb connecting plate with butt weld seam, and then connect the steel tube with the steel tube concrete single leg Welding, and finally pouring concrete into steel pipes.

在这种截面形式中,焊接性能越好,其柱的承载力越高,为此,本实用新型需要保证良好的施焊工艺(可采用组对焊接工艺);组合柱截面的“扩张比”(开孔率)增大,截面高度增加,其刚度和回转半径加大,长细比会减小,稳定承载力得到提高。但是,腹板开孔洞后,其抗剪性能会受到一定的影响。因此,实际工程中,应视实际受力情况而控制“扩张比”或开孔率;单肢由钢管及混凝土组合而成,由于钢管内的空间有限,因此浇注混凝土时不便振捣,故宜选用自密实混凝土。In this section form, the better the welding performance, the higher the bearing capacity of the column. For this reason, the utility model needs to ensure a good welding process (pair welding process can be used); the "expansion ratio" of the combined column section (Opening ratio) increases, the section height increases, its stiffness and radius of gyration increase, the slenderness ratio decreases, and the stable bearing capacity is improved. However, after the web is opened with holes, its shear performance will be affected to a certain extent. Therefore, in actual engineering, the "expansion ratio" or the opening ratio should be controlled according to the actual stress situation; the single limb is composed of steel pipe and concrete. Due to the limited space in the steel pipe, it is inconvenient to vibrate when pouring concrete, so it is advisable to Use self-compacting concrete.

本实用新型的基本特征:以较为经济的方式,提高其单肢承载力,改善了传统格构柱虚轴的工作性能,提高其刚度和稳定承载力,缩小了传统格构柱虚、实轴的性能差别。The basic features of the utility model: in a relatively economical way, the bearing capacity of a single limb is improved, the working performance of the virtual axis of the traditional lattice column is improved, the rigidity and stable bearing capacity are improved, and the virtual and real axis of the traditional lattice column are reduced. performance difference.

本实用新型的组合柱,由于单肢钢管中浇注了混凝土,钢管内部的混凝土可以有效地防止钢管发生局部屈曲,而钢管对其内部混凝土的约束作用使混凝土处于三向受压状态,提高了混凝土的抗压强度;两者共同发挥作用,构件的延性性能明显改善,耗能能力提高,具有优越的抗震性能。In the composite column of the present invention, since concrete is poured into the single-leg steel pipe, the concrete inside the steel pipe can effectively prevent the local buckling of the steel pipe, and the restraint effect of the steel pipe on the concrete inside makes the concrete be in a three-way compression state, which improves the strength of the concrete. The compressive strength; the two work together, the ductility performance of the component is significantly improved, the energy dissipation capacity is improved, and it has superior seismic performance.
