The rebar bolt is an anchoring system widely used in construction and underground mining projects due to its efficiency and ease of installation. It consists of a corrugated steel bar, typically used in concrete reinforcement, which provides high structural strength. One end of the bar is threaded to a length of 150-200 mm to allow the installation of a nut with an anchor plate. The other end is cut at a 45-degree angle, facilitating its insertion into the drilled hole.
The main body of the bolt has longitudinal ridges or corrugations along its surface. These corrugations significantly increase the anchoring capacity by generating greater friction between the bolt and the surrounding rock, improving structural stability in excavated areas.
The inner end of the bolt, with its 45-degree cut, allows for faster and more efficient insertion into the borehole. On the other hand, the threaded outer end is used to tension the bolt and secure the anchor plate. This is achieved by tightening a nut, which can be hexagonal or round, depending on the project’s requirements.
The rebar bolt offers versatility in its installation. It can be installed using resin cartridges for a fast-setting solution or with cement mortar for more traditional applications. Both methods ensure a secure and long-lasting anchor.
Thanks to its robust and efficient design, the rebar bolt is a reliable solution for stabilizing walls, ceilings, and other structures in construction, mining, and tunneling projects. It guarantees safety and long-term performance, making it an essential component in ground support systems.
