Large-span truss type floor structure and construction method thereof
The invention relates to the technical field of steel structure construction, in particular to a large-span floor system structure, in particular to a large-span floor system truss structure design technology and a construction method thereof. Comprising primary trusses and secondary trusses, the primary trusses are arranged at intervals, the adjacent primary trusses are connected through the secondary trusses arranged at intervals, and each primary truss comprises an upper chord beam, a lower chord beam located below the upper chord beam, the lower chord beam and a web member; wherein the lower chord beam has an arched radian. The invention provides a large-span floor structure which aims to improve the building clearance requirement and exceed the conventional span, so that the building space arrangement is flexible and diversified, and the requirements of owners are easily met. In the aspect of construction, bolt connection is mainly adopted in construction, construction is convenient, the characteristics of high strength and high quality of steel are fully utilized, the structure is low in cost, high in bearing capacity and convenient to construct, damage to the structure is effectively reduced under the temperature effect and the earthquake effect, and the structure is safe and reliable.
本发明涉及钢结构施工技术领域，尤其涉及大跨楼盖结构，具体是一种大跨度楼盖桁架结构设计技术及其建造方法；包括主桁架和次桁架，主桁架间隔布置，在相邻主桁架之间通过间隔设置的次桁架连接，所述主桁架包括上弦梁、位于上弦梁下方的下弦梁以及将下弦梁、腹杆；其中下弦梁呈现出拱形弧度。本发明提供一种大跨度楼面结构，为提高建筑净空需求，超越常规跨距，使得建筑空间布置灵活多样，容易满足业主需求。在施工方面，施工主要采用螺栓连接，施工方便，充分利用钢材具有强度高、质量强的特点，使得该结构成本低，承载力高，施工方便，在温度作用下和地震作用下有效减小结构的损害保证结构安全可靠。
