正六边形钢-混凝土组合空腹双重网格梁楼盖
摘要：
本实用新型公开了一种正六边形钢－混凝土组合空腹双重网格梁楼盖，楼盖的平面形状为由六边形柱网所形成的框架组成正六边形，该正六边形的对角线长度L为30米≤L≤48米；在六边形柱网内连接有钢－砼组合空腹梁，钢－砼组合空腹梁三向交叉组成大正三角形网格，钢－砼组合空腹梁的结构高度为对角线长度L的20～24分之一；在每个大正三角形网格内设有由密肋梁三向交叉连接组成的小正三角形网格，在大正三角形网格和小三角形网格上覆盖有混凝土楼面板；在钢－砼组合空腹梁的下肋梁底部连接有槽形钢板。本实用新型具有结构整体性好、结构高度小、所占空间少、混凝土和钢材用量较少等优点，特别适合于建筑大跨度多边形平面、多层多功能大厅使用。
摘要（英）：

The utility model discloses a regular hexagon steel-concrete combined double-layer hollow grid beam floor. The planar shape of the floor a regular hexagon formed by a frame formed by a hexagonal column grid, wherein the length L of the diagonal of the regular hexagon ranges from 30 meters to 48 meters; the inside of the hexagonal column grid is connected with a steel-concrete combined hollow beamswhich are intercrossed in three directions to form a large regular triangle grid; the structural height of the steel-concrete combined hollow beams is 1/24 to 1/20 of the length L of the diagonal; asmall regular triangle grid formed by concentrated reinforced concrete beams intercrossed in three directions is arranged in each large regular triangle grid; concrete floor plates are covered on thelarge regular triangle grids and the small regular triangle grids; and the bottom of lower reinforced concrete beam of the steel-concrete combined hollow beams is connected with a trough steel plate.The floor has the advantages of high structural integrity, small structural height, small space occupation, small concrete and steel consumption and the like, and is particularly suitable to be used in a large-span multi-edge plane of a building and a multi-layer multifunctional hall.
