Embedded type mandrel anti-floating fixing device for cast-in-place concrete hollow floor slab
The invention discloses an embedded type mandrel anti-floating fixing device for a cast-in-place concrete hollow floor slab. The embedded type mandrel anti-floating fixing device comprises a bottom formwork, a slab bottom reinforcing mesh, an anti-floating reinforcing mesh and a slab top reinforcing mesh, and mandrels are supported at the top of the bottom formwork through mandrel supports; the slab bottom reinforcing mesh is arranged between the mandrels and the bottom formwork, a reinforcing bar cushion block is cushioned at the bottom of the slab bottom reinforcing mesh, the anti-floating reinforcing mesh covers the top end surface of the mandrels, the slab top reinforcing mesh is arranged at the top of the anti-floating reinforcing mesh, and a gap is reserved between the slab top reinforcing mesh and the anti-floating reinforcing mesh; and the slab bottom reinforcing mesh is connected with support steel pipes at the bottom of the bottom formwork through binding, the slab bottom reinforcing mesh is connected with the slab top reinforcing mesh through connecting pieces, the anti-floating reinforcing mesh is connected with the slab bottom reinforcing mesh through connecting pieces, and the connecting pieces are distributed on the periphery of each mandrel. The embedded type mandrel anti-floating fixing device solves the problems that the PPE macromolecular alloy combined mandrels of the cast-in-place concrete hollow floor slab easily float upwards and deviates horizontally in the concrete pouring process, so that the thickness of an upper slab and the thickness of a lowerslab are ensured, and the quality requirement is met.
本发明公开了一种现浇混凝土空心楼盖板埋入式芯模抗浮固定装置，包括底模板、板底钢筋网、抗浮钢筋网和板顶钢筋网，芯模由芯模支架支撑于底模板顶部；板底钢筋网设置于芯模与底模板之间，且底部垫有钢筋垫块，抗浮钢筋网罩于芯模的顶端面，板顶钢筋网设置于抗浮钢筋网的顶部，板顶钢筋网与抗浮钢筋网之间留有间隙；板底钢筋网与底模板底部的支架钢管通过绑扎连接，板底钢筋网与板顶钢筋网之间通过连接件连接，抗浮钢筋网与板底钢筋网通过连接件连接，且连接件分布于各个芯模的四周；本发明解决了现浇混凝土空心楼盖板PPE高分子合金组合芯模在混凝土浇筑过程中容易出现上浮及水平偏位的问题，从而确保上板与下板的厚度，保证质量要求。
