背景技术
近年来，超大型会议、会展、高铁站和飞机航站楼等大型建筑广泛运用了形态各异的大跨度空间结构体系，以实现丰富的造型。而对于大型建筑所需要的大跨度空间结构体系，大跨悬臂结构成为大跨度空间结构体系的重要部分，相应地，大跨度幕墙对建筑表现越来越重要。随着建筑对超大跨度、悬挂式幕墙的需求增多，悬挂式幕墙结构突破了传统的幕墙结构概念，成为主体结构的一部分，然而大跨度悬挂幕墙的设计与传统幕墙相比难度大，且必须要考虑与主体结构协同工作，因此如何提供一种实现建筑与结构的融合，且满足与主体结构协同工作的大跨度悬挂幕墙成为亟待解决的问题。
发明内容
本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种大跨度刚性悬挂幕墙结构体系，该悬挂幕墙结构体系可应用于大型大跨度建筑的幕墙结构中，可确保幕墙与主体结构的协同设计，实现建筑与结构的融合。
本发明的目的可以通过以下技术方案来实现：

进一步地，所述下月牙结构包括平面桁架及设于平面桁架上的幕墙板，位于中央位置的下月牙结构的幕墙板的长度向位于两侧的幕墙板的长度依次减小，下月牙结构的幕墙板构成与上月牙结构相反方向弯曲的立面中间厚两端尖的月牙状弯曲面结构。
进一步地，所述幕墙吊柱包括两个吊柱竖板及设于两个吊柱竖板之间的多排横隔板，吊柱竖板与横隔板组成格构形式。

具体实施方式
下面结合附图和具体实施例对本发明进行详细说明。显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
实施例
本实施例涉及一种大跨度刚性悬挂幕墙结构体系，该结构体系包括上月牙结构1、下月牙结构2、月牙吊柱3和幕墙吊柱4。上月牙结构1、下月牙结构2分别设于建筑内部主体结构5的顶部和底部。上、下月牙结构的平面上造型为弧形月牙造型，立面中间厚两端尖。幕墙吊柱4是由两侧的吊柱竖板41以及设于两侧吊柱竖版41之间的多排横隔板42组成的格构形式的梯子型的吊柱。
上月牙结构1包括多个三角形平面桁架，上月牙结构1中央部分的三角形平面桁架的高度最高，其两侧对称设置高度依次减小的三角形平面桁架。各三角形平面桁架的根部与屋面桁架和核心筒相连。各个三角形平面桁架上以及各三角形平面桁架之间紧密安装幕墙板，幕墙板为宽度相同的矩形板结构，位于中央部分的幕墙板的尺寸最长，中央部分幕墙板两侧的幕墙板的长度依次减小。各个三角形平面桁架上的幕墙板构成立面中间厚两端尖的月牙状弯曲面。四个上月牙结构1围合在建筑内部主体结构5四周，使得四个上月牙结构1平面上构成矩形或方形组合结构。
下月牙结构2根据造型布置平面桁架，重量通过多根等间隔设置的圆柱体结构的月牙吊柱3吊挂在屋面上月牙结构1的各幕墙板上。位于上月牙结构1中央部分的月牙吊柱3的长度最小，中央部分月牙吊柱3两侧的月牙吊柱3的长度依次增大。平面桁架上同样安装有幕墙板，因上月牙结构1的形状为月牙状弯曲面，则幕墙板构成与上月牙结构1相反方向弯曲的立面中间厚两端尖的月牙状弯曲面结构。
下月牙结构2通过竖向长圆孔销轴节点与楼板结构6的楼面的封边梁连接，可保证下月牙侧向和切向约束、竖向可以自由滑动。这种约束形式保证了幕墙结沿侧向具有足够的刚度，减小幕墙在风荷载的水平变形；竖向滑动能够保证月牙吊柱和幕墙吊柱在升降温作用下可以自由滑动，避免吊柱受压。竖向长圆孔销轴节点即包括长圆孔、设于长圆孔中的销轴之间的结构节点。可采用耳板、封板、垫板、销轴的组合结构，即将封板固定在侧向楼板封边梁的内侧壁上，将耳板穿过封板并固定在侧向楼板封边梁侧壁内，耳板上设有用以安装销轴并使销轴竖向滑动的长圆孔，耳板的两 侧设有垫板，垫板外侧设有钢板，各钢板、垫板与耳板通过销轴连接，钢板架设在幕墙吊柱4的吊柱竖板41与横隔板42上。
建筑内部主体结构5的上部屋盖悬挑构件与下部屋盖悬挑构件之间设有玻璃幕墙，多个幕墙吊柱4安装在上月牙结构1内侧(靠近玻璃幕墙一侧)与下月牙结构2内侧(靠近玻璃幕墙一侧)之间，用于承担玻璃幕墙的重量。以上月牙结构1端部的三角形桁架的一端为起点，每隔一段距离布置一道幕墙吊柱4，各幕墙吊柱4的顶端吊挂在上月牙结构1的三角形桁架下，各幕墙吊柱4的底端与下月牙结构2的平面桁架连接。如图5、6所示，幕墙吊柱4由两侧的吊柱竖板41与横隔板42组成格构形式，其中吊柱竖板41与横隔板42均采用焊接矩形管，相邻横隔板42设有两种间距，即第一排横隔板与第二排横隔板之间的距离为第一间距，第二排横隔板与第三排横隔板之间的距离为第二间距，第三排横隔板与第四排横隔板之间的距离为第一间距，以此类推。第一间距的长度大于第二间距。吊柱竖板41的顶部吊挂在上月牙结构1的三角形桁架下，吊柱竖板41的底端与下月牙结构2的平面桁架连接。梯子形组合截面形式超出了常规格构柱的概念，在进行精细化分析的基础上，满足了现有规范规定的受拉构件长细比显示，同时满足建筑师对组合吊柱造型的要求。
在本实施例中，提供了将本发明大跨度刚性悬挂幕墙结构体系的应用案例，即应用至某会议中心外部吊挂幕墙中，该建筑高度51.05m，平面尺寸207mx207m。利用本体系的幕墙吊柱的两吊柱竖板中心间距为600mm，相邻横隔板间距为3.5m和1.0m(即第一排横隔板与第二排横隔板之间的距离为3.5m，第二排横隔板与第三排横隔板之间的距离为1.0m，第三排横隔板与第四排横隔板之间的距离为3.5m，以此类推)。在本实施例中，作为优选方案，四个下月牙结构2一共通过118根月牙吊柱3吊挂在上月牙结构1的三角形平面桁架上。悬挂幕墙的中间高度27m，四角高度45m，总面积约2.6万m 2。幕墙和下月牙总重12100t。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的工作人员在本发明揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保 护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
