混凝土预制构件厂通常采用钢模生产构件。钢模的用钢量一般占预制厂设备总用钢量的一半多。钢模投资占建厂总投资的15～20%。目前一些老厂的钢模已使用多年,需要更新。因此,模板改革很有意义。构件的质量与钢模板的结构构造有密切关系。底模刚度差,楼板板面会出现斜向对角线裂缝。北京某厂折线窑外墙板流水生产线,投产后一直存在墙板裂
Concrete prefabricated component plants usually use steel molds to produce components. The amount of steel used in steel molds generally accounts for more than half of the total amount of steel used in precast plant equipment. Steel mold investment accounts for 15 to 20% of the total investment in the plant. At present, the steel molds of some old factories have been used for many years and need to be updated. Therefore, the template reform makes sense. The quality of the components is closely related to the structural construction of the steel formwork. The bottom mold stiffness is poor, diagonal diagonal cracks appear on the floor slab surface. A line of kilns in a factory in Beijing was used to produce the wallboard water production line.
