第一、预应力空心板、高强钢丝电弧剪断工艺 建筑行业中,预应力空心屋面板属民用及工业建筑中不可缺少之构件,混凝土空心屋面板是我单位预制厂常年生产的产品,每年生产量达1500立方米以上。实践中认识到预应力空心板生产后经过养生出厂前的断筋工艺是一项复杂,数量又大的烦重劳动,而传统的断筋方法一是利用剪刀,二是利用电气焊,既笨重,劳动强度又大,如果用剪刀断筋影响空心板的质量,很难达到从预制板块的根部断筋,另外剪刀的寿命也太短,使用剪刀的劳动强度也太大,如果用电气焊断筋,没有专业知识和操作合格证无法进行。
First, prestressed hollow slabs and high-strength steel wire arc shearing technology In the construction industry, prestressed hollow roofing slabs are indispensable components for civil and industrial construction. Concrete hollow roofing slabs are produced by our prefabrication plant year-round. Annual production capacity. Up to 1500 cubic meters. In practice, it is recognized that the production of pre-stressed hollow slabs after the production of the broken ribs before delivery is a complicated, heavy-duty process. The traditional method of breaking tendons is the use of scissors and the use of electric welding. , The labor intensity is great. If the quality of the hollow plate is affected by the shearing ribs of the scissors, it is difficult to reach the ribs from the root of the prefabricated plate. In addition, the service life of the scissors is too short, and the labor intensity of using the scissors is too great, if the electric welding is used. Ribs, no expertise and operational certification cannot be performed.
