Abstract

一种预应力复合锚具,它包括:锚环、楔形锚片、螺母,所述的锚环带有外螺纹,锚环与螺母螺接。本实用新型结构紧凑、操作方便,可实现预应力调整,易于推广使用。

Description

预应力复合锚具
本实用新型涉及一种预应力复合锚具。
已有的预应力锚具大多由锚环、锚片等组成,这些由锚环、锚片组成的锚具不能实现预应力调整。因此,有必要提供一种预应力可调整的复合锚具。
本实用新型的目的是提供一种预应力可调整的复合锚具,该锚具结构紧凑,使用方便。
为达到上述目的,本实用新型采用以下技术方案:预应力复合锚具包括:锚环、楔形锚片、螺母,所述的锚环带有外螺纹,锚环与螺母螺接。
以下结合附图对本实用新型作以下描述:
图1:本实用新型结构示意图
图2:图1的侧视图
图3:本实用新型使用状态图
图1,图2中,2为锚环,锚环带有外螺纹,1为螺母,锚环与螺母配合(螺接),3为楔形锚片,锚片与锚环配合。
图3中,锚具的螺母1与承压板5接触,需要拉伸的钢铰线4放入导管6内,8为防止拉伸时混凝土开裂的螺旋筋,7为拉环。
本实用新型操作使用过程是:钢筋4穿过顶压头、千斤顶,再穿过工具锚,千斤顶的中缸活塞的右侧进压,这时将工具锚顶紧,钢筋被拉伸,当千斤顶中缸活塞的左侧进压,本复合锚具顶紧,钢筋与楔形锚片、锚环成为一体,需调整预应力时,可调节锚环外的螺母。
本实用新型的优点:本锚具结构紧凑,使用方便,可实现预应力调整,例如可用来弥补预应力的钢材松弛造成的预应力损失,以及其他用途。
