Composite thermal insulation space superposed truss floor slab and construction method thereof
The invention relates to a composite thermal insulation space superposed truss floor slab and a construction method thereof, the composite thermal insulation space superposed truss floor slab comprises a cast-in-place layer, a thermal insulation layer and a thin plate layer which are sequentially arranged from top to bottom, a plurality of dovetail grooves are formed in the top of the thermal insulation layer in the main stress direction, and latticed ribbed beam grooves are formed in the bottom of the thermal insulation layer; the dovetail grooves are communicated with the ribbed beam grooves through connecting holes penetrating through the heat preservation layer, the bottom of the heat preservation layer is poured to form an integrated thin plate layer, ribbed beams and connecting ribs, the ribbed beams and the connecting ribs correspond to the ribbed beam grooves and the connecting holes respectively, and the top of the heat preservation layer is poured to form an integrated cast-in-place layer and dovetail protrusions corresponding to the dovetail grooves. The composite heat-preservation space superposed truss heat-preservation floor slab provided by the invention is superposed to form a space truss structure, so that the structural strength is well guaranteed, and the requirements of an assembly type building technology are met. In the construction process, cast-in-place is carried out, a traditional wood formwork does not need to be erected, formwork removal is avoided, the self weight is light, transportation, construction and installation are convenient, and the comprehensive cost is lower.
本发明涉及一种复合保温空间叠合桁架楼板及其施工方法，其包括从上往下依次设置的现浇层、保温层和薄板层，所述保温层顶部沿主受力方向设置有若干燕尾槽，所述保温层底部设有网格状的肋梁槽，所述燕尾槽与肋梁槽之间通过贯穿保温层的连接孔相连通，所述保温层底部浇筑形成一体的薄板层以及分别与肋梁槽和连接孔相对应的肋梁和连接肋，所述保温层顶部浇筑形成一体的现浇层和与燕尾槽相对应的燕尾突起。本发明提供的复合保温空间叠合桁架保温楼板叠合而成空间桁架结构，结构强度得到很好保证，满足装配式建筑技术的要求。施工时进行现场浇筑，不用支设传统木模板、免拆模，而且自重较轻，便于运输和施工安装，综合成本更低。
