Abstract

本实用新型公开了一种锚杆托梁,包括加工有锚杆孔3的托梁体1,该托梁体1横截面的上端两侧具有圆弧形的凸起2。此种结构的锚杆托梁强度高、安全性能好。

Description

锚杆托梁
技术领域
本实用新型涉及一种锚杆托梁,与锚杆配合使用,用于矿井锚网巷道顶板的支护。
背景技术
现有的锚杆托梁一般为梯形钢带,是用φ8~10mm的钢筋焊接而成,受力后,纵向钢筋容易拉断,横向焊口容易开裂,强度低,安全性差。
发明内容
本实用新型的目的在于提供一种强度好、安全性能好的的锚杆托梁。
本实用新型是这样实现的:一种锚杆托梁,包括加工有锚杆孔的托梁体,该托梁体横截面的上端两侧具有圆弧形的凸起。
本实用新型的优点是:锚梁两端具有凸起结构,起到加强筋的作用,使产品的强度得到有效加强,凸起结构与托梁体可以一体轧制或锻压而成,能保证整体强度,安全性大幅提高。
附图说明
以下结合附图对本实用新型的具体实施方式做进一步说明。
图1为本实用新型主视图。
图2为图1的A-A剖视图。
具体实施方式
如图所示,托梁体1宽度方向的中部开设锚杆孔3,并沿纵向间隔分布,托梁体1宽度方向的上端两侧具有连续且纵向延伸的凸起2,凸起2的截面形状为圆弧形。凸起2结构起到加强筋作用,使用时能有效提高强度,增加安全性。
