Product Overview

Anti-floating anchor is an indispensable geotechnical anchoring component for underground building foundations. Taking high-strength precision rolled threaded steel bar (PSB bar) as the main tendon body, matched with dedicated anchor nuts, bearing plates and connecting sleeves, the anchor is fixed in rock-soil layers via pressure grouting to generate powerful bonding friction force. It effectively counteracts the upward buoyancy force generated by underground water on basement floors, underground parking lots, underground comprehensive pipe galleries and deep foundation structures, preventing foundation heave, slab cracking and structural safety hazards. 

Core Advantages

1.High-Strength PSB Bar Main Body 
Adopt high-strength precision rolled rebar, overall full-length continuous thread structure, stable tensile performance, strong ultimate pull-out bearing capacity to satisfy long-term underground load requirements.

2.Complete Matching Anchoring Fittings 
Supporting flat nuts, conical nuts, thickened anchor bearing plates and connecting sleeves are self-manufactured with high quality steel via precision machining. Perfect thread matching, uniform force transmission during pre-tightening construction.

3.Excellent Anti-Corrosion & Long Service Life 
Multiple anti-rust solutions: hot galvanizing for humid basement environments; epoxy coating for coastal saline soil, acidic and alkaline stratum, greatly extending the service life of anchors buried underground permanently.

4.Flexible On-site Construction & Length Adjustment 
Arbitrary length splicing via threaded couplers according to actual anchoring depth of geological conditions; convenient anchoring locking operation without field threading or welding procedures, shortening project construction cycle.

5.Stable Pull-out Test Pass Rate 
Strict sampling pull-out test before delivery; official test reports can be provided to smoothly pass third-party inspection and project acceptance of overseas underground engineering projects.
