Construction method of large-gradient inverted conical funnel-shaped top plate
The invention relates to a construction method for a large-gradient inverted conical funnel-shaped top plate. The construction method comprises the steps that a BIM model is established; a concrete cushion layer of the supporting system is poured; popping up the center line of the inverted conical funnel and the side line of the structure; erecting vertical rods and horizontal rods of the support scaffold, and adjusting different heights of the vertical rods of the scaffold to enable the whole support system to be in an inverted cone shape; a complete and closed inverted-cone-shaped template working surface is formed at the bottom; checking and accepting a supporting system and a template; funnel wall steel bars are bound; laying a double-layer template; pouring is conducted one by one in sequence; and removing the mold. The upper and lower double-layer formworks are laid, it is guaranteed that the large-angle inverted-cone-shaped funnel top plate is integrally closed, the pouring hole is reserved, it is guaranteed that concrete does not excessively flow downwards in the pouring process, and therefore the concrete pouring appearance quality is improved, the later-period repairing cost is avoided, and the engineering economic benefits are improved.
本发明涉及一种大坡度倒圆锥漏斗形顶板的施工方法，建立BIM模型；对支撑系统的混凝土垫层进行浇筑；弹出倒锥形漏斗的中心线以及结构的边线；支撑脚手架立杆及水平杆搭设，通过调整脚手架每个立杆的不同高度，使整个支撑系统呈现倒锥形的支撑；底部形成完整封闭的倒锥形模板作业面；支撑系统及模板验收；漏斗壁钢筋绑扎；铺设双层模板；按顺序逐个进行浇筑；拆模。本发明通过铺设上下双层模板，保证大角度倒圆锥形漏斗顶板的整体封闭，并预留浇筑洞口，保证浇筑过程中混凝土不向下过度流淌，以此提升混凝土浇筑外观质量，避免后期修补费用，提高工程经济效益。
