What is a shear key in steel structures?

-

 In steel structure engineering , the column base connection serves as the pivotal interface linking the superstructure to the concrete foundation below. It must safely and reliably transmit various loads from the upper structure: vertical pressure , uplift forces , bending moments , and horizontal shear forces . When horizontal shear forces become substantial, the friction alone between the column base plate and the concrete foundation surface proves insufficient to resist them. At this juncture, a critical small component becomes indispensable—the shear key . Shear keys, as the name suggests, are structural steel connection components specifically designed to resist and transmit horizontal shear forces. Essentially, they are short steel members. Installation location: Typically welded or anchored to the base plate of a steel column (or other load-bearing components such as equipment supports ), with its lower end embedded in the concrete foundation or concrete structure cast ...

What is the truss welding method?

  truss roof Most of the rods in joist structures are welded at the nodes. Before welding, the webs and chords need to be cut in advance according to the shape of the weld seam of each member to be welded, which requires cutting of the web ends and slotting of the chords. Since the joist structure is intersected by coherent line between the rods and rods, the shape of rod end section is complicated, so in the actual cutting process, two methods of mechanical automatic cutting process and manual cutting process are generally used.

truss roof A truss refers to a lattice structure composed of round rods connected to each other at the ends. Wide range of applications and economical and practical today. Such as exhibition centers, stadiums or some other large public buildings have been used.   In recent years, with the continuous growth of my country's steel production, steel structures, with their own advantages, account for an increasing proportion of buildings, and steel pipe structures have also made great breakthroughs. The biggest advantage of the steel pipe structure is that it can perfectly combine the functional requirements, sensory requirements and economic benefits of people's buildings. The pipe truss structure in the steel pipe structure is favored by people with its unique advantages. ______________________ Whatsapp/Tel:+ 86/13056229023 E-mail:safs121@safsteelstructure.com www.safsteelstructure.com

The development status of the space frame structure space frame   structure has been developed greatly in the last 30 years, and has been widely used inside and outside. space frame   structure plan arrangement is flexible, space shape is beautiful, convenient for building shape processing and decoration, decoration, can adapt to different span, different plane shape, different support conditions, different functional needs of the building.   Especially in the roof structure of large and medium span, the space frame   structure shows its superiority and is used in large number of large sports buildings, public buildings, industrial buildings, and also widely used in the roof of some small buildings, such as gas stations, toll stations, large canopies. In recent years, with the wide application of electronic computers and the development of computing technology, the design efficiency of the space   frame structure has been greatly improved. The construction and i...

What are the economic advantages of a space frame structure?

-

  The advantage of the space frame  structure is that all the components can be spliced and installed by the factory. It only takes 45 days to 2 months for the roof of a large-scale industrial plant, and 8 to 12 months if the reinforced concrete building is used. The short project cycle greatly reduces unnecessary costs.   Because the weight of the space frame  itself is light, under normal circumstances, it is not necessary to do pile foundations, which can save investment. According to the current domestic market price in China, the cost of light steel structure is already lower than that of reinforced concrete structure. When the span of the space frame  structure is larger, the use space can be greatly increased, and its advantages are more obvious, which is also one of the competitions it relies on. big advantage.   Generally, the truss can be designed with a span of about 20 meters, and the supporting columns should be placed. However, the span of the...

Common connection methods for steel structures

-
图片
Common connection methods for steel structures : 1. A steel structure is made up of a number of elements combined. The role of the connection is to combine the plates or sections into members in a certain way, or to combine several members into a whole structure in order to ensure that it works together. Therefore, the connection method and its quality directly affect the working performance of the steel structure. 2. At present, the steel structure is commonly connected by welding, bolting or riveting. The earliest common bolt connection was used from about the middle of the 18th century, and the rivet connection was introduced in the 1920s, while the weld connection appeared in the second half of the 19th century. Since the middle of the century, high-strength bolted connections have been developed.
