水泥桁条一般采用“平模”生产,产品抗压强度低,台面利用率低,混凝土消耗量大,制品表面光洁度差,易弯曲变形。江苏省徐州市广山水泥制品厂,研制成功“立模”生产水泥桁条新工艺。近年在徐州市郊区几家生产厂推广应用,取得了良好的效果。“立模”生产桁条比“平模”生产有四大好处: 一、制品质量显著提高。“平模”生产桁条在预制过程中,钢筋受压多造成偏心,使用时偏心受力,易弯曲变形,降低了抗压强度。
Cement purlins generally use “flat mold” production, the product has low compressive strength, low table utilization, large concrete consumption, poor surface finish, easy to bend and deform. Xuzhou Guangshan Cement Products Factory in Jiangsu Province has successfully developed a new process for the production of cement purlins. In recent years, several production plants in the suburbs of Xuzhou have popularized their applications and achieved good results. There are four main advantages for the production of purlins in the “Vertical Form” production than the “flat form” production: 1. The quality of products is significantly improved. In the process of prefabrication, the “flat die” production slats will cause eccentricity when the steel bar is under pressure, eccentric force when used, easy to bend, and reduce the compressive strength.
