Anti-floating-free combined core mold for hollow floor slab
The invention discloses an anti-floating-free combined core mold for a hollow floor slab. The anti-floating-free combined core mold comprises a core mold body, a grid plate and transverse supporting rods, wherein an upper face and a lower face of the core mold body are open, the grid plate covers an upper face opening and a lower face opening of the core mold body and is fixedly connected with the core mold body, meshes in regular or irregular shapes are formed in the grid plate, the size of the meshes is smaller than the diameter of fine sand for building concrete, and the transverse supporting rods stretch across the opening of the core mold body and are used for supporting the upper grid plate and the lower grid plate. The anti-floating-free plastic steel combined core mold for the hollow floor slab is light in weight and convenient to combine, air generated during concrete pouring can be effectively exhausted through the meshes in the grid plate, pressure intensity inside and outside the core mold is equal, an air bag cannot be formed in the core mold, therefore, the core mold cannot float upwards, and anti-floating cost of the core mold is reduced.
本发明公开了一种空心楼板用免抗浮组合芯模，包括芯模本体、网格板、横向支撑杆，所述芯模本体上、下面为敞口，所述网格板覆盖在芯模本体的上、下面敞口并与芯模本体固连，在网格板上设置有规则或不规则形状的网孔，所述网孔的尺寸小于建筑混凝土用细砂直径，所述横向支撑杆横跨在芯模本体的敞口上用于支撑上、下网格板。本发明的空心楼板用免抗浮塑钢组合芯模质量轻、组合便捷，网格板上的网孔可有效排除浇注混凝土时产生的空气，使芯模内外压强相等，芯模内不会形成气囊，从而使得芯模不会上浮，降低了芯模的抗浮成本。
