Cold storage floor construction method and cold storage floor
The invention discloses a cold storage floor construction method, and belongs to the technical field of cold storage heat preservation. The cold storage floor construction method comprises the following steps: S1, foundation bearing platforms are poured in matrix arrangement, soil is backfilled, and a gravel layer and a foundation cushion layer are sequentially laid on a backfill soil layer and the foundation bearing platforms; S2, a bearing frame, a formwork and reinforcing steel bars are erected on the foundation cushion layer, concrete stand column formworks correspond to the foundation bearing platforms, and the formworks and the bearing frames are removed after pouring is completed; S3, a damp-proof layer is laid; and S4, a concrete floor surface layer is laid. The invention further provides a cold storage floor. The cold storage floor comprises a base layer, an overhead heat insulation layer, a damp-proof layer and the concrete floor surface layer which are sequentially arranged from bottom to top; the base layer comprises the foundation bearing platforms, the backfill soil layer, the gravel layer and the foundation cushion layer, the overhead heat insulation layer comprises concrete stand columns and a concrete top plate; the damp-proof layer is laid on the concrete top plate; and the overhead heat insulation layer can separate the floor surface layer from the base layer, cold bridge generation is reduced, cooling capacity is prevented from being transferred downwards, and cold-caused expansion of a soil layer is avoided.
本发明公开了一种冷库地坪施工方法，属于冷库保温技术领域，包括以下步骤：S1、浇筑呈矩阵排列的基础承台并回填土，在回填土层和基础承台上依次铺设碎石层、基础垫层；S2、在基础垫层上支设承重架、模板以及钢筋，混凝土立柱模板对应着基础承台，完成浇筑后拆除模板和承重架；S3、铺设防潮层；S4、铺设混凝土地坪面层；还提供了一种冷库地坪，包括由下到上依次设置的基层、架空隔热层、防潮层和混凝土地坪面层，基层包括基础承台、回填土层以及两者顶面上依次铺设的碎石层和基础垫层；架空隔热层包括混凝土立柱和混凝土顶板，防潮层铺设在混凝土顶板上；架空隔热层能够将地坪表层与基层隔开，减少冷桥产生，阻止冷量下传，避免土层冻臌。
