Description
技术领域technical field
本发明属于建筑钢结构技术领域，特别是涉及一种正六边形蜂窝网格状钢空腹楼盖盒式结构的制造方法。The invention belongs to the technical field of building steel structures, and in particular relates to a method for manufacturing a regular hexagonal honeycomb mesh steel hollow floor box structure.
背景技术Background technique
传统常规结构体系中，若搭盖多层大跨度建筑，其用钢量大幅度增加，投资者为了节约造价，在当时土地量较多且购制费相对较低情况下，大跨度单层工业厂房铺天盖地涌现，大跨度公共与工业建筑局限于单层。随着土地购制费用提高和相关节约土地资源政策出台，2007年，空间网格盒式结构被提出，同时伴随着各项空间网格盒式结构专利被提出和工程应用，它们的出现，打破了长期以来在大跨度公共与工业建筑领域里传统钢框架及门式刚架体系。与此同时“装配整体式空间钢网格盒式结构新体系”的出现，多层大跨度公共与工业建筑相继在全国多个地区出现，但这些新技术的空间网格组成，均局限为方形，即正交正放和正交斜放两种，而城市的多层大跨度公共建筑，其楼盖的天棚造型要求多样化，并要求节约投资，不足以完全满足建筑需求。正六边形蜂窝网格状钢空腹楼盖盒式结构可以丰富各类多层大跨度公共建筑室内网格造型，形成“安全、合理、先进、经济”的新型结构体系。正六边形蜂窝网格状钢空腹梁在车间厂房加工时，单元占的面积过大无法装车运输。In the traditional conventional structural system, if a multi-storey long-span building is built, the amount of steel used will increase significantly. In order to save construction costs, the investor chose a large-span single-story industrial Factory buildings sprang up everywhere, and long-span public and industrial buildings were limited to a single floor. With the increase of land purchase system costs and the promulgation of related land resource saving policies, in 2007, the spatial grid box structure was proposed. It has replaced the traditional steel frame and portal frame system in the field of long-span public and industrial buildings for a long time. At the same time, with the emergence of "a new system of assembled integral space steel grid box structure", multi-storey and long-span public and industrial buildings have appeared in many regions of the country, but the spatial grid composition of these new technologies is limited to square , that is, two kinds of orthogonal vertical and orthogonal oblique, and the multi-storey long-span public buildings in the city require diversified ceiling shapes and investment savings, which are not enough to fully meet the architectural needs. The regular hexagonal honeycomb grid steel hollow floor box structure can enrich the indoor grid shape of various multi-storey and long-span public buildings, forming a new structural system that is "safe, reasonable, advanced and economical". When the regular hexagonal honeycomb mesh steel hollow beam is processed in the workshop, the area occupied by the unit is too large to be loaded and transported.
