Abstract

本发明公开一种三维夹克式套板连接器,包括第一三维夹克式套板、以及和所述第一三维夹克式套板成镜像的第二三维夹克式套板,被连接的每个构件都是宽缘工字钢型钢。本发明以简单一致的方式利用三维连接板,并适用于连接具有宽缘工字钢型钢所有可能的节点类型;利用贯穿总深度的螺纹杆,及其与常规的腹板加劲肋的耦合关系,以传递剪力和弯矩通过节点。这种类型的剪切传递机制类似于钢筋混凝土梁和柱中的箍筋。所有组件和部件可以在车间预制,并在现场方便地用螺栓固定在一起。该节点的优点包括具有更高的强度和延塑性、既结实又简单的连接、组件质量高且体积小,便于储存和运输。简言之,它消除了传统的螺栓连接和/或焊缝连接的所有固有缺点和问题。

Description

使用三维夹克式套板和拉杆的螺栓连接的钢节点
技术领域
发明了一种全新的结构钢节点类型。这是夹克式套板连接系统,其使用三维接点板和拉杆来实现特别优越的结构性能,所述结构性能优于任何传统的螺栓连接或焊缝接的节点,传统节点都使用二维(即平面的)角撑板和/或侧面板。该新型节点的优点包括具有更高的强度和延塑性、既结实又简单的连接、组件质量高且体积小,便于储存和运输。此外,它们消除了传统的螺栓连接和/或焊缝连接所有固有全部缺点和问题。本发明是一种通用连接系统,可适用于由宽翼缘工字钢型材组成的任何钢框架和桁架。它基本重新定义了结构钢连接节点的概念,并具有改革目前的钢结构工程市场的潜力,将有显着的经济和社会影响。
发明内容
本发明公开一种三维夹克式套板连接器,其所连接的每个构件都是宽缘工字钢型钢,所述套板连接器包括:第一三维夹克式套板;以及第二三维夹克式套板,其为所述第一三维夹克式套板的镜像,所述两个三维夹克式套板是用螺栓连接至所述工字钢构件节点的正反俩侧面,其中三维夹克式套板包括:平面侧板,其被切割成节点的侧面投影形状;成双成对夹紧板,其被焊接在侧板的周边,并有预先钻好的螺栓孔。该连接系统具有三个非常独特的特征:(1)本发明首次系统地将三维连接板引入行业,并以简单一致的方式解决了所有可能的节点类型。(2)本发明利用贯穿总深度的螺纹杆,及其与常规的腹板加劲肋的耦合关系,以传递剪力和弯矩通过节点。这种类型的剪切传递机制类似于钢筋混凝土梁和柱中的的箍筋。虽然被广泛用于钢筋混凝土结构中多年,但这还是该机制第一次被应用于钢框架和桁架之中;(3)所有组件和部件可以在车间预制,并在现场方便地用螺栓固定在一起。应用本发明,在没有现场焊接的情况下所有钢框架的拼装都成为切实可行,包括以下常规的高性能抗震钢框架:特种抗弯矩框架(SMRF)、偏心支撑框架(EBF)和特种同心支撑框架(SCBF)。(请注意,目前市场上还没有全部用螺栓连接的SMRF、EBF和SCBR,其原因是由于传统的螺栓连接节点无法以切合实际的成本达到所需的强度和延塑性。换言之,这些节点都是全部或部分地使用了焊接连接。)
