Haiyan Bolt provide such anchors like Wedge anchor, Toggle anchor, Sleeve Anchor, etc. It’s also be called as Expansion bolt which is a special threaded connection used to fix the pipeline support/Hanger/bracket or equipment on the wall, floor slab and column.
The fixation of expansion screw is to use the pull angle to promote the expansion to produce friction grip force, so as to achieve the fixation effect. One end of the screw is threaded and the other end has a degree of vertebra. A steel sheet is wrapped on the outside, and half of the iron sheet cylinder has several notches. They are stuffed into the holes made on the wall together, and then the nuts are locked. The nuts pull the screws outward to pull the vertebra degree into the steel sheet cylinder. The steel sheet cylinder is expanded, so it is tightly fixed on the wall, generally used for fastening the protective fence, awning, air conditioning, etc. on the cement, brick and other materials. However, its fixing is not very reliable. If the load has large vibration, it may loose, so it is not recommended to install the ceiling fan. The principle of the expansion bolt is that after the expansion bolt is punched into the hole on the ground or wall, the nut on the expansion bolt is tightened with a wrench, and the bolt moves outward, while the outer metal sleeve does not move, so the big head under the bolt expands the metal sleeve to make it full of the hole, at this time, the expansion bolt cannot be pulled out.
Expansion bolts are widely used in various construction and installation projects. Their main uses and functions are as follows:
● Fixing Heavy Objects: They are commonly used to attach heavy objects to walls, ceilings, or floors. For example, in industrial settings, large machinery and equipment can be firmly fixed to the ground using expansion bolts to prevent them from moving or vibrating during operation. In commercial buildings, heavy signage or display racks are often secured to walls with expansion bolts to ensure their stability and safety.
● Installing Electrical and Plumbing Fixtures: In the field of electrical and plumbing installations, expansion bolts play a crucial role. They are used to mount electrical switchboards, junction boxes, and plumbing pipes and brackets. By providing a secure attachment point, expansion bolts ensure that these fixtures remain in place and function properly over time, even under the stress of electrical currents or water pressure.
● Structural Reinforcement: In some cases, expansion bolts are used for structural reinforcement purposes. For example, when adding new structural elements to an existing building, such as beams or columns, expansion bolts can be used to connect the new elements to the existing structure. This helps to distribute loads evenly and enhance the overall strength and stability of the building.
● Secure Fastening in Different Materials: Expansion bolts can be used in a variety of materials, including concrete, brick, and stone. When inserted into a pre - drilled hole, the bolt expands as it is tightened, creating a strong and secure connection. This makes them suitable for a wide range of applications where different types of substrates need to be fastened together or when objects need to be attached to hard surfaces.
In summary, expansion bolts are essential fasteners that provide reliable and durable connections in many construction and installation scenarios, ensuring the safety and stability of various objects and structures.
