Anti-float anchor assembly and anchor plate for an anti-float anchor assembly

By using an anchor plate in the anti-buoyancy anchor assembly, the gaps between the anchor rod and the sleeve, as well as between the sleeve and the concrete base slab, are sealed using grout outlet and grout inlet holes, thus solving the water seepage problem, improving the waterproofing effect, and reducing construction costs.

AI Technical Summary

Technical Problem

After tensioning, the relative displacement between the existing anti-buoyancy anchor rod and the casing, as well as between the casing and the concrete base slab, causes water seepage, resulting in the failure of the base slab's waterproofing.

Method used

An anchor plate is designed, including a first grout outlet hole, a second grout outlet hole, and a grout inlet hole. These holes are connected to the gaps between the anchor rod and the sleeve, and between the sleeve and the concrete base plate. During grouting, the grout can be directly injected to seal these gaps, forming an effective waterproof seal.

Benefits of technology

This achieves long-term seepage prevention through dual leakage channels in the anchor bolt assembly, ensuring the waterproof effect of the concrete base slab and reducing construction difficulty and cost.

Abstract

This application relates to the field of building engineering and discloses an anti-buoyancy anchor bolt assembly and an anchoring plate for the anti-buoyancy anchor bolt assembly. The anti-buoyancy anchor bolt assembly includes an anchor bolt sleeve, an anchor bolt reinforcement, and an anchoring plate. The anchor bolt sleeve is inserted into a concrete base slab; the anchor bolt reinforcement is inserted into the anchor bolt sleeve, with its top extending beyond the top of the anchor bolt sleeve; the anchoring plate is fitted onto the top of the anchor bolt reinforcement, and its bottom wall abuts against the top of the anchor bolt sleeve. The anchoring plate includes a first grout outlet communicating with a first gap formed between the anchor bolt reinforcement and the anchor bolt sleeve, a second grout outlet communicating with a second gap formed between the anchor bolt sleeve and the concrete base slab, and grout inlets communicating with both the first and second grout outlets. The anti-buoyancy anchor bolt assembly and the anchoring plate for the anti-buoyancy anchor bolt assembly of this application can conveniently and effectively seal leakage channels at the anchoring point, improving the waterproofing effect of the building base slab.
