具有恢复功能的部分填充结构框架装配节点 技术领域
本发明涉及建筑技术领域，公开了一种具有恢复功能的部分填充结构框架装配节点。
背景技术
部分填充式钢-混凝土组合结构(partially encased composite structures，PECS)是在H形钢等开口截面构件的外包轮廓范围内填充混凝土，并依据性能要求在混凝土中设置纵筋、箍筋及抗剪键等部件的组合结构。与纯钢结构相比，混凝土的加入使得结构的抗火、抗扭刚度等性能得以改善，承载力和刚度也进一步提高；与钢筋混凝土结构相比，部分填充式钢-混凝土组合结构在相同承载力条件下展现出更好的延性；与型钢混凝土相比，该种结构具有构件可预制化程度高、模板用量少等优点。
在框架结构中，节点作为主体结构体系的枢纽，既是承受梁、柱、板等构件传递各种荷载的受力点，也是多种工程交汇施工的重要部位。节点的受力性能影响到整个结构的安全，它的施工速度也影响到整个工程结构的进度。普通钢结构梁—柱节点中，钢梁翼缘与柱翼缘焊接连接、钢梁腹板与柱子翼缘螺栓连接仍是最普遍采用的形式，柱—柱节点普遍采用全焊接或全螺栓连接。而在部分填充式钢-混凝土组合结构中，由于钢材开口截面部分填充混凝土的原因，上述连接方式操作不便，不再适用。
发明内容
为了克服上述现有技术的缺点，本发明的目的在于提供一种具有恢复功 能的部分填充结构框架装配节点，通过在框架节点位置使用后张拉钢绞线以及形状记忆合金长螺栓等耗能减震构件，实现了部分填充式钢-混凝土组合柱与钢梁的全装配式干式螺栓连接，同时解决了部分包裹混凝土柱与钢梁以及中高层建筑中不可避免的柱—柱拼接连接，安装简单方便，在能有效发挥混凝土与钢两种材料的性能的同时也有效提高了结构的预制化程度，大大提高了施工效率。
为了达到上述目的，本发明采用的技术方案为：
一种具有恢复功能的部分填充结构框架装配节点，包括部分填充钢-混凝土组合柱和H型钢梁，其特征在于，所述的部分填充钢-混凝土组合柱为节段式，由上柱和下柱在节点处拼接完成，上、下拼接柱段均在H型钢柱的两翼缘之间设加劲肋，并在开口截面处填充角部为圆角的模块式混凝土；节段柱之间通过在拼接端头处穿入钢绞线并后张拉连接完成，且拼接处的柱翼缘处设置记忆合金长螺栓连接装置，保证连接的可靠性、增强节点的耗能能力；H型钢梁与柱通过柱段上预设的角钢连接件及形状记忆合金长螺栓、高强螺栓实现连接。
进一步的，所述的加劲肋对称设置在节段式部分填充钢-混凝土组合柱H型钢柱部分的腹板两侧，其中柱端部设置的端头加劲肋在外侧角部设置螺栓孔，以在螺栓孔中穿入钢绞线，实现节段柱之间的拼接。
进一步的，所述钢绞线经后张拉处理，并在端头加劲肋处锚固。
进一步的，所述的模块式混凝土四角设置为圆角，内配置纵筋及箍筋，通过在H型钢柱的腹板上预焊的抗剪栓钉与钢柱紧密联系。
进一步的，所述的在上段节段柱H型钢腹板上设置凸式盒式构件，下段 节段柱H型钢腹板上设置凹式盒式构件，凸式盒式构件外表面与凹式盒式构件内表面尺寸相匹配，角部均设置为立体圆角，两者可恰好完全接触，辅助上、下柱段拼接中准确对位，且两者拼接完成后形成盒式抗剪键，增强节点处拼接柱子的抗剪能力。
进一步的，所述的上段节段柱端头加劲肋和下段节段柱端头加劲肋之间均设置有竖向端板，端头处构造为半封闭，其内填充混凝土。
进一步的，所述的纵向角钢连接件沿梁长方向对称设置在与H型钢梁连接侧的上下段柱翼缘上，纵向角钢连接件两角肢及钢梁的翼缘、腹板处均设螺栓孔，纵向角钢连接件与钢梁翼缘在靠近柱表面第一排螺栓孔处使用形状记忆合金长螺栓连接，其余螺栓孔位置及纵向角钢连接件与钢梁腹板之间使用高强螺栓连接。
进一步的，所述的横向角钢连接件对称设置在非与梁连接侧的柱子翼缘上，横向角钢连接件两肢之间设角钢加劲肋，在未与柱翼缘焊接的角肢上设置螺栓孔，上柱段与下柱段的横向角钢连接件之间通过形状记忆合金长螺栓连接。
进一步的，钢梁腹板在靠近柱子端开短缝，长度与纵向角钢连接件等长。
与现有技术相比，本发明的有益效果：
(1)本发明在梁柱连接节点处同时设置柱与柱的拼接节点，通过一系列措施保证连接的可靠性，同时解决了部分包裹混凝土柱—钢梁以及在中高层建筑中不可避免的柱—柱拼接连接问题。
(2)本发明所采用的部分填充钢-混凝土组合柱之间主要通过后张拉钢绞线连接，有效解决了部分填充混凝土给结构柱连接带来的不便，连接紧密、 现场施工简便。
(3)柱子横向加劲肋之间在开口截面处填充的模块式混凝土四角为圆角，可有效避免柱子受弯时一侧混凝土受拉开裂。
(4)节段柱连接端头处设置“盒”式抗剪键，一方面使得节段柱之间的连接更加紧密，另一方面也提高了节点处柱子的抗剪能力。
(5)通过在柱壁外设置形状记忆合金长螺栓以及梁腹板开缝的措施，有效提高了节点的耗能能力，同时有效保护主要结构件构件不被破坏，且本发明构件之间可全部采用现场拼接连接，满足了预制装配化的施工工艺需要，有助于实现建筑结构工业化生产，有效提高生产效率。
