Liweiyuan Anchor bolts for steel structures are commonly used fixing connectors in construction projects. Their function is to firmly fix the steel structure to the concrete foundation to ensure the stability and safety of the structure. The following is a detailed introduction to the product:
Anchor bolts for steel structures are embedded in concrete by pre-embedded or post-embedded methods. They can withstand the tension, shear force and vibration during equipment operation to ensure a stable connection between the steel structure and the foundation. It is widely used in infrastructure such as railways, highways, bridges, tower cranes, large-span steel structures and large buildings.
Anchor bolts for steel structures are mainly divided into the following types:
1. Pre-embedded anchor bolts: Positioned and installed before pouring concrete, high-precision positioning is required, and they are suitable for new construction projects. Among them, the L-type or J-type anchor bolts have hooks at the end to enhance the anchoring effect; the anchor plate anchor bolts have steel plates welded at the bottom to disperse the load, which are suitable for heavy equipment or frame structures.
2. Post-type anchor bolts: After the concrete hardens, they are drilled and installed. They are highly flexible and are often used in expansion or renovation projects. Post-type anchor bolts include expansion bolts, chemical anchor bolts, and mechanical bolts.
The material of anchor bolts for steel structures is mainly carbon steel (such as Q235B, Q355B), and alloy steel (such as 40Cr) can be used in high-strength occasions. In corrosive environments, 304/316 stainless steel should be used. In order to extend the service life, anchor bolts also need to be treated with anti-corrosion, such as hot-dip galvanizing (50-80μm), epoxy coating or Dacromet process.
1. Design points: It is necessary to comprehensively consider factors such as static load (equipment deadweight), dynamic load (operation vibration), wind load and seismic force, and determine the number, diameter and burial depth of bolts through mechanical models. The burial depth is usually 25-30 times the bolt diameter to ensure a stable connection between the bolt and the foundation.
2. Installation process: The installation process of embedded anchor bolts includes positioning and laying out on the template, fixing the bolt group with a fixing frame, pouring concrete and real-time monitoring to prevent deviation, and rechecking the position after concrete curing. The installation process of post-installed anchor bolts includes drilling, cleaning holes, and glue injection installation.
3. Maintenance and care
The anchor bolts for steel structures need to be checked regularly during use to ensure that there are no cracks, looseness, or breakage at the joints such as welds, bolts, and rivets. If problems are found, they should be tightened or replaced in time. In addition, the surface of the steel structure needs to be cleaned regularly to avoid the accumulation of dust and dirt, and the anti-corrosion coating should be updated regularly to extend the service life.
Liweiyuan steel structure anchor bolts play a vital role in construction projects. Our technicians will strictly control the design, selection, installation, and maintenance to ensure the stability and safety of the entire structure.
Common specifications and models of anchor bolts mainly include the following:
M6, M8, M10, M12, M16, M24, M30, M36, M42, M48, etc. Among them, "M" represents the diameter of the anchor bolt, and the number behind it represents the specific value, that is, the specific nominal diameter of the bolt.
In addition to the diameter specification, the length of the anchor bolt is also an important parameter, and its length range is usually between 80 and 1500 mm.
