Novel cast-in-place concrete hollow floor and pore-forming core mold
The invention discloses a novel cast-in-place concrete hollow floor and a pore-forming core mold. The novel cast-in-place concrete hollow floor comprises a core mold and a quick-easy metal net, wherein the quick-easy metal net is fixedly arranged on the outer surface of the core mold; the interior of the core mold is of a multi-cavity structure defined by a light filling material and a thin-wall material or a shell structure composed of a thin-wall material; the number of cavities in the multi-cavity structure is not less than 2; the multi-cavity structure can ensure the overall strength of afilling body, the concrete loss when a box body is damaged is reduced to the maximum extent, and quality safety accidents are reduced; the use of the quick-easy metal net ensures the bite force of a contact surface, avoids the occurrence of defects such as hollowing, two layers of skin and peeling, reinforces a rib beam structure, and avoids the development of side cracks; and the adhesion mode ofmeshes and a closing tongue and the improvement of shear marks reduce the tension degree of the closing meshes, ensure the slurry wrapping effect, and improve the overall strength and rigidity of thequick-easy metal net.
本发明公开了一种新型现浇混凝土空心楼盖及成孔芯模，其中，包括芯模和快易金属网，所述快易金属网固定设置在所述芯模的外表面，所述芯模内部为由轻质填充材料、薄壁材料围成的多腔体构造或由薄壁材料组成的壳体构造，所述多腔体构造中腔体数量不少于2个；多腔体构造能够保证填充体整体强度，最大程度上降低箱体破损时混凝土亏方量，降低质量安全事故；快易金属网的使用，保证了接触面的咬合力，避免空鼓，两层皮，剥落等缺陷的发生，并且对肋梁结构进行了补强，避免了侧面裂缝的发展；网孔和收口舌头的黏连方式及切痕的改进降低了收口网孔的张拉度，保证了包浆效果，提高了快易金属网整体的强度和刚度。
