Nuclear engineering steel truss composite floor slab and construction method thereof
The invention relates to the technical field of nuclear engineering civil engineering industrial construction, in particular to a nuclear engineering steel truss composite floor slab and a construction method thereof. The nuclear engineering steel truss composite floor slab comprises a profile steel truss and a steel truss, wherein the profile steel truss stretches across wall bodies on the two sides of the length direction; the profile steel truss comprises a lower chord member, the lower chord member is arranged on the side, close to the wall body, of the profile steel truss in the thickness direction, and the lower chord member extends into the wall body in the length direction; and the prefabricated concrete bottom plate is formed by pouring prefabricated bottom plate reinforcing bars and the lower chord member together, so that the profile steel truss and the prefabricated concrete bottom plate form an integral truss prefabricated plate. According to the nuclear engineering steel truss composite floor slab provided by the invention, overall cooperative stress of the profile steel truss and the prefabricated concrete bottom plate can be realized, the bearing capacity of the truss prefabricated slab is improved, the applicable span of the nuclear engineering steel truss composite floor slab is increased, and mold-free, support-free and industrial production of nuclear engineering large-span and super-thick floor slabs can be realized.
本发明涉及核工程土建工业化施工技术领域，具体涉及一种核工程钢桁架叠合楼板及其施工方法。所述核工程钢桁架叠合楼板包括：型钢桁架，横跨于长度方向两侧的墙体上；所述型钢桁架包括下弦杆，所述下弦杆设置于所述型钢桁架厚度方向上靠近墙体的一侧，且所述下弦杆沿长度方向伸入至墙体中；预制混凝土底板，由预制底板配筋与所述下弦杆共同浇筑形成，以使所述型钢桁架与所述预制混凝土底板形成整体的桁架预制板。本发明提供的核工程钢桁架叠合楼板，能够实现型钢桁架与所述预制混凝土底板整体协同受力，提高所述桁架预制板的承载能力，增大了所述核工程钢桁架叠合楼板的适用跨度，能够实现核工程大跨、超厚楼板的免模免撑和工业化生产。
