Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, and more particularly to a permanent anti-floating anchor rod body. Background Art

[0002] Introducing this equipment and its uses in high-rise buildings, bridges, tunnels and other projects. In order to ensure the overall stability and safety of the structure, anti-floating anchor rods are also needed to enhance the anti-floating ability of the structure. In underground projects such as basements, underground garages, and underground passages, the rise of groundwater levels will generate upward buoyancy on the concrete structure, which may cause structural damage. In order to resist this buoyancy, anti-floating measures need to be adopted, and anti-floating anchor rods are one of the important technical means.

[0003] Deficiencies of existing technology: In underground building structures, due to the rich water content in the underground soil layer, it produces a large upward water buoyancy on the underground structure. In existing underground structures, pull-out piles or conventional anti-floating anchor rods are used to offset the reaction force. In existing technologies, cracks, leakage, and water leakage in the bottom plate of underground structures often occur. When pull-out piles are used for anti-floating, the cost is increased and the cost of use is high. When conventional pull-out anchor rods are used for anti-floating, the structural force is unreasonable. Because the anchor rods themselves have poor waterproof performance, they are exposed to groundwater for a long time. After being soaked in the leaking groundwater, they are easily corroded, which is not conducive to the long-term use of the anchor rods and reduces the service life of the anchor rods. In addition, groundwater will leak along the direction of the anchor rod setting, causing groundwater to flow into the underground structure, which not only affects the normal use of the later building, but also affects the connectivity between the anchor rod and the base of the basement, reduces the bearing pressure of the anchor rod, and reduces the protection of the anchor rod to the basement, thereby greatly increasing the later maintenance cost of the structure.

[0024] The outer ring sidewall of the threaded steel bar 3 is sprayed with a polyurea coating 305, and the outer ring sidewall of the threaded steel bar 3 is provided with a threaded ring 307. The polyurea coating 305 greatly improves the durability of the anchor rod body and prolongs its service life. At the same time, the design of the threaded ring 307 enables the anchor rod body to be quickly and firmly connected to other components, such as the anchor bearing head 4. The threaded structure at the top facilitates quick connection with the threaded steel bar (3). Through cement grouting, the bonding force between the anchor rod and the soil is further enhanced, thereby improving the anti-floating effect.
