Description

一种圆管与工字型钢梁的贯连节点A connecting joint between a circular pipe and an I-shaped steel beam

技术领域technical field

本实用新型属于建材技术领域,涉及钢结构建筑物用构件,特别是一种圆管与工字型钢梁的贯连节点。The utility model belongs to the technical field of building materials, and relates to components for steel structure buildings, in particular to a connecting node between a round pipe and an I-shaped steel beam.

背景技术Background technique

传统网壳结构杆件多以圆钢管为主,结构的杆件内力多以轴力为主。随着我国综合国力的提高,国内建筑结构呈现出向着更大跨度、更大面积、更复杂型体等方面发展,新体型下的网壳杆件除轴力外还承受了相当大的弯矩作用。箱型截面杆件因其较好的抗弯、抗扭性能,加之其棱角分明,呈现出良好的力学美,受到越来越多的建筑师亲睐,在剧院、体育场馆等大型空间网壳结构中应用越来越广泛。The rods of the traditional reticulated shell structure are mostly round steel pipes, and the internal force of the rods of the structure is mostly axial force. With the improvement of my country's comprehensive national strength, domestic building structures are developing towards larger spans, larger areas, and more complex shapes. The reticulated shell members under the new shape also bear a considerable bending moment in addition to the axial force. effect. Box-section rods are favored by more and more architects because of their good bending and torsion resistance, and their sharp edges and corners, showing good mechanical beauty. They are favored by more and more architects. The application in the structure is more and more extensive.

随着箱型截面杆件在大跨网壳结构中应用的普及,随之而来的节点问题成为了一大难题。箱型截面杆件网壳的节点除了常规承受轴力作用外,还需考虑其所承受的弯矩作用。现阶段对于此种节点多采用直接相贯节点、焊接空心球节点或铸钢节点。对于焊接空心球,目前的研究都针对配合圆钢管,对配合矩形管的焊接球节点尚无相关研究,焊接球是否能达到完全理想的刚接,承担节点处较大的弯矩作用还有待进一步研究,同时对于箱型截面构件而言,与焊接球连接处的相贯线相当复杂,加工和安装难度都较大。对于采用直接相贡节点,由于箱型截面杆件不同于圆管,其存在着方向性,对于建筑曲面造型奇特的单层网壳而言,箱型截面构件呈现出弯扭性能,采用直接相贯处理,对于详图、工厂的加工制作及现场的施工均提出了较高的要求,且往往存在着安装精度低、焊接质量不好的现象,同时箱型截面弯扭构件的加工制作成本大幅度提高。而采用铸钢节点,虽然能很好地解决相贯节点中出现的问题,然而对于节点数量大且节点样式多样的情况,铸钢节点往往存在着加工周期长,项目成本高的问题。With the popularization of the application of box-section members in large-span reticulated shell structures, the subsequent node problems have become a major problem. In addition to the normal bearing of axial force, the joints of box-section reticulated shells also need to consider the bearing of bending moment. At present, direct intersecting joints, welded hollow ball joints or cast steel joints are mostly used for such joints. For welded hollow balls, the current research is aimed at matching round steel pipes. There is no relevant research on welded ball joints matched with rectangular pipes. Whether the welded ball can achieve a completely ideal rigid connection and bear the large bending moment at the joint remains to be done. At the same time, for box-section members, the intersecting line at the joint with the solder ball is quite complicated, and it is difficult to process and install. For the direct relative joints, since the box-section members are different from the round pipes, they have directionality. For the single-layer reticulated shell with a strange architectural surface shape, the box-section members show bending and torsion performance. Higher requirements are put forward for detailed drawings, factory processing and on-site construction, and there are often phenomena of low installation accuracy and poor welding quality. increase in magnitude. The use of cast steel joints can well solve the problems in intersecting joints, but for the case of large number of joints and various joint styles, cast steel joints often have the problems of long processing cycle and high project cost.

另外现有网壳节点无法应对不同规格的工字钢进行灵活调节;再者节点中心的支撑强度不够,箱型截面杆件之间的支撑强度也需进一步提高。In addition, the existing reticulated shell nodes cannot flexibly adjust to I-beams of different specifications; moreover, the support strength at the center of the nodes is not enough, and the support strength between the box-section members needs to be further improved.
