Abstract

本实用新型涉及混凝土用钢纤维,更具体地是指一种弓型钢丝切断钢纤维,其特征在于钢丝纤维的两端各有一个冲压成弓型的钩,且两端的弓型钩扭弯成≥20°角度,掺和在混凝土中可提高混凝土抗拉,抗弯拉强度及韧度系数,适用于抗裂,抗冲击,抗疲劳,耐磨、变形量大等性能要求较高的工程。

Description

弓型钢丝切断钢纤维
一、技术领域:
本实用新型涉及混凝土用钢纤维,更具体地是指一种弓型钢丝切断钢纤维,掺和在混凝土中,能增强混凝土抗拉,抗弯拉强度,适用于抗裂,抗冲击,抗疲劳,耐磨等性能要求较高的工程或部位。
二、背景技术:
混凝土用的钢纤维按其生产工艺可分为钢丝切断纤维,薄板剪切纤维,熔抽纤维和铣削纤维,钢丝切断纤维的抗拉强度最高。
三、发明内容:
本实用新型需要解决的技术关键,在于改变钢丝切断纤维结构,来提高钢纤维混凝土的抗拉强度及与砂浆粘结度。
为此,把直径0.5-1.0mm钢丝截成长度为25-60mm纤维状,在钢纤维的两端,各有一个冲压成弓型的钩,并将二个弓型钩扭转成一个≥20°角度。
由于钢丝切断纤维本身抗拉强度高,当二端带有弓型的钩且有≥20°扭角时,可提高与砂浆的粘结度,又可提高钢纤维混凝土韧度系数。
四、附图说明:
图1为本实用新型的结构示意图
在图1中1为钢丝纤维,2为弓型钩
五、具体实施方式:
参考附图1,本实用新型把直径0.5-1.0mm钢丝截成长度为25-60mm纤维状,在钢纤维两端各有一个冲压成弓型钩2,并将两个弓型的钩2扭转一个≥20°角度。
本实用新型掺和在混凝土中成为钢纤维混凝土,具有抗拉,抗拉强度韧性系数高,适用于抗裂,抗冲击,抗疲劳,耐磨变形量大等性能要求较高的工程部位。
