Underground house building construction technology based on assembly type combined mold

XU ZHENJIA

The invention provides an underground house building construction technology based on a fabricated combined mold, and relates to the technical field of building construction. The underground house building construction technology comprises the following steps that a box type outer wall mold provided with an anti-floating mold is stably arranged on a cushion layer and connected with a side wall guide wall mold; binding the raft steel bar net rack and the wall steel bar net rack; concrete is poured into the anti-floating formwork, the box type outer wall formwork and the raft reinforcing mesh frame; a box type inner wall mold is installed on the side wall guide wall mold, and concrete is poured into the wall pouring mold to form a wall; the box type outer wall mold, the box type inner cavity mold, the side wall guide wall mold and the anti-floating mold are disassembled, and the diagonal stand column outer mold is installed; concrete is poured into the diagonal stand column outer molds, girders are assembled on nuts of the diagonal stand column outer molds, and the assembled girders are connected with the stand column diagonal molds; and a top plate bearing beam is installed on the assembling girder, and pouring forming is conducted after a surface layer formwork is laid. The method has the advantages of being easy to operate, saving materials and being high in construction efficiency.

本发明提出了一种基于装配式组合模具的地下房建施工工艺，涉及建筑施工技术领域。该地下房建施工工艺包括以下步骤：将装有抗浮模的箱型外墙模稳定就位垫层上，并连接边墙导墙模；绑扎筏板钢筋网架和墙壁钢筋网架；并向抗浮模、箱型外墙模、筏板钢筋网架内浇筑混凝土；边墙导墙模上安装箱型内墙模，并向墙壁浇筑模具内浇筑混凝土形成墙壁；拆卸箱型外墙模、箱型内腔模、边墙导墙模和抗浮模，安装对角立柱外模；在对角立柱外模内浇筑混凝土，并在对角立柱外模的螺母组装大梁，使组装大梁与立柱对角模链接；在组装大梁上安装顶板承载梁，铺设面层模板后浇筑成型。本发明具有操作简单、节省材料和施工效率高的优点。
