Description

Anchorage device sealing steel cap leakage-proof device

Technical Field

The invention relates to the technical field of engineering construction, in particular to a leakage-proof device for a sealing steel cap of an anchorage device.

Background

When a bridge is built on a road, in order to prevent the concrete from generating cracks too early, a pre-pressure is needed to be applied to the concrete, namely, a jack is used for tensioning a steel strand rope in a tension area of the concrete, the retraction force of the steel strand rope is used for enabling the tension area of the concrete to be stressed in advance, so that the pre-pressure is stored firstly, when a member bears the tension generated by external load, the pre-pressure in the concrete in the tension area is offset firstly, then the concrete is tensioned along with the increase of the load, the elongation of the concrete is limited, and the occurrence of cracks is delayed.

The part of the steel stranded rope extending out of the concrete pouring area is protected by the protective cap, when the temperature is reduced, the protective cap shrinks when being cooled, a gap is generated between the protective cap and the fixed platform, so that a large amount of oxygen and water vapor are in contact with the steel stranded rope, the steel stranded rope is oxidized and corroded, the pre-pressure in concrete is reduced, the service life of a bridge floor or a road surface is shortened, and therefore the anchorage device for sealing the steel cap is provided.
