A refractory anchor brick

The utility model discloses a fire-resistant anchoring brick, which comprises a connecting part, a groove, a hole end, a protective layer, a hanging hole, a hanging head, a brick body, a set seat, a reinforcing layer, a base layer, a fire-resistant shell, a protective layer, a fire-resistant layer Layer and reinforcement core. The steel bar passing through the hanging hole can be protected by the protective layer and groove, the surface of the steel bar can be protected by providing a protective layer, and the firmness of the hanging head can be improved, and then the protective material can be installed inside the hole end, which can Protect the steel bars at both ends of the hanging holes, prevent the steel bars and the brick body from affecting the overall strength due to thermal expansion and cold contraction, and improve the overall firmness of the anchor bricks; a refractory shell can be formed by smearing a layer of refractory material on the surface of the brick body, and then pass through the refractory layer. The fire resistance of the brick body can be improved, the internal strength of the brick body can be improved through the reinforcement layer, and the compressive and shear resistance of the brick body can be enhanced by installing the reinforcement core inside the reinforcement layer, and the protective layer can be placed on the reinforcement layer and reinforced. The core avoids corrosion, which affects the strength of the brick body.
