What is a steel component?
Steel components are the abbreviation of steel structural parts. They refer to steel structure composite components that can bear and transfer loads and are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels, cold-bent or welded through connectors. They have a wide range of uses, as follows:
1. Building structure field
Steel components are widely used in construction. As a large and powerful country in the construction industry, China has a particularly wide range of applications and research on steel components in the construction field. The use of steel structures can reduce the weight of buildings and improve the seismic performance and service life of buildings. At the same time, steel structures have fast construction speed and short construction period, which can improve engineering efficiency. Steel structures can be made into trusses of various shapes and used in roof structures, such as industrial plants, supermarkets, gymnasiums and other buildings. Steel frame structures can also be made into components of various shapes to build large-span spatial structures, such as airports, stations, exhibition centers, etc. With the development of prefabricated buildings, it is also widely used in residential, school and other buildings because of their characteristics of rapid assembly.
2. Industrial facilities
In light industry, steel components are widely used in the manufacture of industrial equipment, passenger cars, and commercial vehicles. They also play a vital role in heavy industry, such as petrochemical plants, power plants, steel mills, and docks. For example, the brass casings of excavators are often welded from steel plates, offering wear and impact resistance. Wind turbine towers are welded from steel pipes and angle steel, offering high strength and stability. In shipbuilding, these components are also widely used in various components, including hulls and masts.
3. Bridge construction field
Steel components have the characteristics of high strength and light weight, and are suitable for making long-span bridges, such as steel arch bridges and steel cable bridges. At the same time,it can also be made into beams of various shapes for making steel beam bridges, which have the characteristics of strong bearing capacity and long service life.
Steel structure purlin is a horizontal roof beam perpendicular to the roof truss or rafters, used to support rafters or roofing materials. The following is a detailed introduction to steel structure purlins.
High-strength bolts for steel structures are a kind of high-strength fasteners specially used for steel structure connection. The following is a detailed introduction.
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 anchor bolts for steel structures.
Anchor bolts are indispensable bolt type steel structure accessories in steel structure buildings. They are mainly used to fasten steel structure building components or equipment to the concrete foundation, and play the role of fixing the foundation and connecting the main body. The following is a detailed explanation of anchor bolt steel structure accessories.
In summary, steel components play an indispensable role in many fields such as building structures, industrial facilities and bridge construction due to their excellent performance and wide applicability. Liweiyuan Steel Structure can provide a full range of services from design, research and development, processing and manufacturing, packaging and delivery, installation guidance, and after-sales maintenance.
Bolt-type steel component connection
Bolt-type steel component connection is a common connection method in steel structure engineering. It mainly connects two or more steel components tightly together through bolts to achieve the stability and bearing capacity of the structure, the following points should also be noted for bolt-type steel component connection:
1. The connection surface should be flat and clean, free of impurities such as oil and rust to ensure that the bolts can fit tightly and transfer loads.
2. The hole position of the bolt should be accurate and the hole wall should be smooth to avoid excessive resistance or damage to the bolt during installation.
3. During the connection process, accessories such as gaskets or washers should be used to disperse the load of the bolts to prevent the surface of the component from being crushed.
4. For high-strength bolt connections, two steps of initial tightening and final tightening are required to ensure that the preload of the bolt reaches the design value.
In short, bolt-type steel component connection is an indispensable part of steel structure engineering. Liweiyuan Steel Structure will ensure the quality and safety of the connection by reasonably selecting the type and specification of bolts, controlling the preload, and paying attention to the connection details.
Classification of bolts for steel structures
Bolts for steel structures can be mainly divided into the following categories:
1. Ordinary bolts
2. High-strength bolts
1. Large hexagonal high-strength bolts: A high-strength bolt connection pair consisting of a high-strength bolt, a nut and two washers.
2. Torsion shear high-strength bolts: Improved on the basis of large hexagonal high-strength bolts, its appearance is "T"-shaped and has better construction performance. The upper and lower sections can be directly locked with a torquer at the same time, and its structural design can reduce the situation of bolt breakage caused by the construction process. A torsion shear high-strength bolt connection pair consists of a high-strength bolt, a nut and a washer.
3. Anchor bolts, also known as anchor bolts, anchor screws, anchor wires, etc., are components used to connect the column base of steel structures to the concrete foundation. During installation, the anchor bolt group is fixed by the steel frame and installed together with the steel cage, and then the concrete is poured. The bolt head should be exposed to a certain length from the concrete surface.
Liweiyuan Steel Structure Factory will provide a combination of various bolts according to the design of the steel structure workshop, which has achieved the characteristics of reasonable economy and convenient use. According to the main classification of bolts, different types of bolts have different applications and functions in steel structures.
