一、概述冷拨丝预应力混凝土多孔板(以下简称多孔板)是砖混住宅建筑采用的主要预制构件,也是乡镇构件厂的主要产品。多孔板的生产过程,由混凝土混合料的制备、钢筋加工、钢丝张拉及构件的成型和养护等基本工艺过程及质量检验等辅助工序组成。本文将对多孔板的成型工艺作简要介绍。多孔板的成型,通常采用振动密实的方法。这种方法能够保证混凝土达到良好的密实度,可以采用干硬性和半干硬性混凝土混合料,从而节约水
I. Overview Cold-picked wire pre-stressed concrete porous plates (hereinafter referred to as perforated plates) are the main prefabricated components used in brick-concrete residential buildings, and are also the main products of township component plants. The production process of the porous plate consists of the preparation of concrete mixtures, the processing of steel bars, the drawing and maintenance of steel wire, and the formation and maintenance of components, as well as other basic processes such as quality inspection. This article will briefly introduce the forming process of porous plates. Porous plate molding, usually using vibration-compact method. This method can ensure that the concrete achieves a good compactness, and can use dry hard and semi-rigid concrete mixture, thus saving water
