为了更详尽的表述上述发明的技术方案，以下列举出具体的实施例来证明
技术效果；需要强调的是，这些实施例用于说明本发明而不限于限制本发明的范围。
本发明提供的铝横梁与铝立柱连接结构，如图1和图2所示，包括铝合金立柱10、铝合金横梁20、套芯连接件30、两个对穿螺杆40以及“几”字形连接件50，所述铝合金立柱10纵向安装，所述铝合金横梁20横向设置于所述铝合金立柱10的侧面。
所述对穿螺杆40横穿所述铝合金立柱10，两个所述对穿螺杆40在水平向和垂向均不重叠(即两个对穿螺杆40不位于同一水平面上，也不位于同一纵轴上)，且靠近室内一侧的对穿螺杆40低于靠近室外一侧的对穿螺杆40，为了明确区分两个对穿螺杆40，以下描述时将靠近室内一侧的对穿螺杆40命名为后螺杆41，将靠近室外一侧的对穿螺杆40命名为前螺杆42。
所述套芯连接件30通过沉头螺钉31固定于所述铝合金横梁20的一端，所述套芯连接件30内设有空腔32，所述空腔32包括与两个所述对穿螺杆40分别对应的两个圆弧槽33。当两个所述对穿螺杆40分别插入对应的圆弧槽33内后，即实现了铝合金横梁20与铝合金立柱10的挂接。
请重点参考图3，所述“几”字形连接件50包括左右两侧的贴合部52和中间的突起部53，其中一个所述贴合部52通过第一盘头螺钉51与所述铝合金立柱10固定连接；另一个所述贴合部52设有开槽54，使该贴合部52夹设于所述铝合金横梁20的突出部位的上下两侧。本申请采用“几”字形连接件50，将“几”字形连接件50与所述铝合金立柱10之间的螺栓固定连接，转换为对铝合金横梁20在垂直方向上的限制，既可避免横梁前端因重力荷载偏心造成的“掉头”现象，也可防止在地震等作用下有可能导致的横梁向上弹起而造成的立柱与横梁连接失效问题。
本申请采用闭口铝横梁，更省料，外观更好，铝横梁的抗扭性能也更好，当连接结构受负风压时，前螺杆42和后螺杆41同时受力，受正风压时，前螺杆42受力，负风压起控制作用；另外，本发明提供的连接结构中，铝合金横梁20拆换更方便，从而减少现场拆换螺钉导致螺纹孔滑丝问题。
请继续参考图1，在一些实施例中，所述铝合金横梁20与所述铝合金立柱10之间还设有柔性垫片21，满足变形及防噪要求，同时对铝合金立柱10和铝
合金横梁20进行保护，同时使连接结构更加稳固。
请重点参考图2，在一些实施例中，靠近室内一侧的所述圆弧槽33(即与后螺杆41对应的圆弧槽)沿水平向延伸，靠近室外一侧的所述圆弧槽33(即与前螺杆42对应的圆弧槽)沿纵向延伸，这种结构便于铝合金横梁20的挂接，同时由于铝合金横梁20的重力作用，使前螺杆42不容易从圆弧槽33内脱出，确保连接结构的有效性。
请重点参考图4a至4c，并结合图1至3，本发明还提供了一种铝横梁与铝立柱连接方法，应用于如上所述的连接结构中，包括如下步骤：
步骤1：在工厂端，将所述对穿螺杆40安装于所述铝合金立柱10上，将所述套芯连接件30安装于所述铝合金横梁20上，本申请通过增加工厂化组装，减少了施工现场的操作，降低了施工难度和施工成本。
步骤2：在施工现场，纵向安装所述铝合金立柱10。
步骤3：如图4a所示，将所述铝合金横梁20抬至待安装位置并倾斜摆放，在一些实施例中，所述铝合金横梁20的倾斜角度为15°～25°，例如19.5°，若倾斜角度过大，则会增加铝合金横梁20的安装难度，若过小，则会导致铝合金横梁20与对穿螺杆40的碰撞，或者对穿螺杆40在圆弧槽33内的挂接深度过小，继而导致对穿螺杆40容易脱出。
步骤4：如图4b所示，将靠近室内一侧的所述对穿螺杆(后螺杆41)套入对应的所述圆弧槽33内，此时前螺杆42位于空腔32内，但未与另一个圆弧槽33挂接；
步骤5：请继续参考图4b，以安装好后的对穿螺杆40(此处指后螺杆41)为轴，旋转所述铝合金横梁20，将另一个对穿螺杆40(指前螺杆42)沿另一个圆弧槽33滑入，使所述铝合金横梁20摆平并完成挂接，如图4c所示；
步骤6：请继续参考图4c，安装所述“几”字形连接件50，完成连接结构的组装。
本发明能够达到安装顺序(先装铝立柱后装铝横梁)、安装方式(铝横梁一端铰接固定另一端横向可滑移铰接固定)等各项施工要求，能够适用于多种建筑幕墙的安装；且安装便捷，成本低。
请参考图5和图6，本发明还提供了一种玻璃幕墙，采用如上所述的连接结
构，更省料，外观更好，玻璃幕墙的安全性高。
请继续参考图5和图6，在一些实施例中，所述玻璃幕墙还包括依次设置的中空钢化玻璃60、压板70以及装饰盖80，所述压板70通过第二盘头螺钉71将所述中空钢化玻璃60与所述铝合金横梁20固定连接，所述装饰盖80扣盖于所述压板70上，保持外观美观。在一些实施例中，中空钢化玻璃60可以采用低辐射(LOW-E)玻璃，使玻璃幕墙具有优异的隔热效果和良好的透光性。
请继续参考图5和图6，在一些实施例中，所述中空钢化玻璃60的表面与所述铝合金横梁20之间，以及所述中空钢化玻璃60的表面与所述压板70之间，均设置有三元乙丙橡胶条61，起到保护、密封以及防噪声的目的。
请继续参考图5和图6，在一些实施例中，所述中空钢化玻璃60的端面的中空部内填充有尼龙垫块62；所述中空钢化玻璃60的端面到所述铝合金横梁20之间依次设有硅酮耐候密封胶和泡沫棒63以及隔热条64，进一步起到隔热、密封以及保护作用。
综上所述，本发明提供的铝横梁与铝立柱连接结构、连接方法以及一种玻璃幕墙，所述连接结构包括铝合金立柱10、铝合金横梁20、套芯连接件30、两个对穿螺杆40以及“几”字形连接件50，所述铝合金立柱10纵向安装，所述铝合金横梁20横向设置于所述铝合金立柱10的侧面；所述对穿螺杆40横穿所述铝合金立柱10，两个所述对穿螺杆40在水平向和垂向均不重叠，且靠近室内一侧的对穿螺杆40低于靠近室外一侧的对穿螺杆40；所述套芯连接件30通过沉头螺钉31固定于所述铝合金横梁20的一端，所述套芯连接件30内设有空腔32，所述空腔32包括与两个所述对穿螺杆40分别对应的两个圆弧槽；所述“几”字形连接件50包括左右两侧的贴合部52和中间的突起部53，其中一个所述贴合部52通过第一盘头螺钉51与所述铝合金立柱10固定连接；另一个所述贴合部52设有开槽54，使该贴合部52夹设于所述铝合金横梁20的突出部位的上下两侧。本申请采用“几”字形连接件50，将“几”字形连接件50与所述铝合金立柱10之间的螺栓固定连接，转换为对铝合金横梁20在垂直方向上的限制，既可避免横梁前端因重力荷载偏心造成的“掉头”现象，也可防止在地震等作用下有可能导致的横梁向上弹起而造成的立柱与横梁连接失效问题；本申请采用闭口铝横梁，更省料，外观更好，铝横梁的抗扭性能也更好；另外，本发明
提供的连接结构中，铝合金横梁20拆换更方便，从而减少现场拆换机制导致螺钉及螺纹孔滑丝问题。
显然，本领域的技术人员可以对发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包括这些改动和变型在内。
