Single-piece recyclable anchor rod

Abstract

The invention relates to a single-piece recyclable anchor rod. The single-piece recyclable anchor rod comprises a bearing core, a bearing seat, a clamping piece, a protective cap and an outer sleeve,wherein one end of the outer sleeve is fixedly sealed with the bearing seat, and the other end of the outer sleeve is fixedly sealed with the tensioning end of the bearing core. When the bearing coreis in a pre-tensioned state, the fixed end of the bearing core and the clamping piece are mutually squeezed, the fixed end of the bearing core is pre-fixed on the bearing seat, the clamping piece is not easy to loosen, and the normal work of an anchorage device is guaranteed; and when the bearing core is recycled, the fixation of the outer sleeve and the bearing core is relieved, an acting force can be applied to the bearing core to enable the bearing core to move into a protective sleeve, the clamping piece is separated from the hole wall of a fixed hole of the bearing core, the clamping piece is separated from the bearing core, and the bearing core can be directly pulled out. According to the single-piece recyclable anchor rod, the bearing core of the anchorage device keeps the pre-tensioned state through the outer sleeve, the structure is simple, and only the bearing core needs to be pushed and pulled when the bearing core is recycled, so that the operation is convenient.

Description

technical field [0001] The invention relates to a single retractable anchor rod. Background technique [0002] Prestressed tensile cores are widely used in construction projects. When the original building loses its function and needs to be demolished and new buildings built, such as shield construction, the prestressed tensile cores used in the original building need to go through a process of breaking the prestressed tensile cores. The construction process increases the construction cost. [0003] The Chinese patent with the authorized announcement number CN210421087U and the authorized announcement date of 2020.04.28 discloses a block-shaped quick-release recyclable anchor, including a guide rail protective cap, a clip, a tapered clamp, a bearing plate, a protective sheath and a steel strand. The open end of the protective cap is connected to the tapered clamp, the end of the steel strand passes through the protective sheath and is inserted into the through hole of the t...
