产品介绍
楔形膨胀螺栓是一种用于混凝土、石材、实心砖等硬质基材的高强度锚固紧固件。通过拧紧螺母，使套管沿楔形芯杆膨胀，与基材紧密咬合形成强力锚固，安装简便、承载力高，广泛用于钢结构、设备固定、管道支架、幕墙、护栏、起重架等工程安装。
产品特点
- 锚固力强：楔形结构膨胀均匀，握裹力大，抗拉、抗剪性能优异。
- 安装便捷：钻孔后直接置入，无需复杂工具，单人即可操作。
- 适用广泛：适配混凝土、天然石材、实心砖等致密基材。
- 高强度耐用：采用碳钢材质，表面镀锌 ，防锈耐腐蚀。
- 定位精准：膨胀后不易松动，适用于重载、震动、长期受力场景。
Product Introduction
Wedge expansion bolts are high-strength anchoring fasteners for hard base materials such as concrete, stone and solid bricks. By tightening the nut, the sleeve expands along the wedge-shaped core rod and tightly engages with the base material to form a strong anchoring force. They are easy to install with high bearing capacity, widely used in steel structure, equipment fixing, pipeline support, curtain wall, guardrail, crane frame and other engineering installations.
Product Features
- Strong anchoring force: Uniform expansion with wedge structure, high grip force, excellent tensile and shear resistance.
- Easy installation: Directly inserted after drilling, no complicated tools, operable by one person.
- Wide applicability: Suitable for dense base materials such as concrete, natural stone and solid bricks.
- High strength & durability: Made of carbon steel, galvanized surface, rust and corrosion resistant.
- Accurate positioning: Not easy to loosen after expansion, suitable for heavy load, vibration and long-term stress scenarios.
