What is a shear key in steel structures?

图片
 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 ...

Structural Steel Bolting Balls: Connecting the Future, Securing the Cornerstone

图片
In the field of steel structure , bolted ball, as an innovative choice of connecting node, is gradually becoming the preferred solution in modern buildings and industrial facilities due to its advantages of easy installation, removable and reorganisable, and low maintenance cost. Compared with traditional welded balls, bolted balls not only simplify the construction process and improve efficiency, but also give the structure greater flexibility and sustainability, which is an indispensable and important component in modern steel structure projects. The core concept of the bolted ball connection technology is to use high-strength bolts to closely connect the components to form a stable and reliable node structure. Compared with welded ball, bolted ball connection does not require on-site welding and avoids thermal stress, deformation and weld quality problems that may arise during the welding process, thus improving the overall stability and safety of the structure. In addition, the bo...

Nodal treatment of roof waterproof construction for large-span buildings

图片
  1, Deformation joints: large-span building roof due to temperature changes, structural deformation and other factors will produce deformation joints. The waterproof construction at the deformation joints should be able to adapt to the deformation of the roof. General use of flexible waterproof construction, such as in the deformation joints filled with polystyrene foam and other thermal insulation materials, and then paste the waterproofing roll-roofing material on both sides, the coil should be used in the empty pavement method or point bonding method, leaving enough space for expansion and contraction, and then in the coil surface to install a metal or plastic cover, to play a protective and decorative role. 2, Light windows and roof junction processing: in some large-span building roof will be set on the light windows, this part is the key node of waterproofing. First of all, we must ensure that the light window and roof structure is firmly connected, and then at the juncti...

What is a coal bunker?

图片
Coal bunker , is a structure used for storing coal. Coal bunkers play an important role in thermal power plants, coal mines and coal marshalling stations. Depending on the specific application scenario and design, there are various types of coal bunkers, such as circular coal bunkers, square coal bunkers and open coal yards. Safety Management of coal bunkers Preventing spontaneous combustion of coal: Since coal itself contains certain moisture and volatile substances, long-term exposure to the air may lead to spontaneous combustion, so the safe management of coal bunkers is of great significance in preventing spontaneous combustion of coal. Ensure the quality of coal: coal in the coal bunker usually needs to be stored for a long time, if not managed properly, it may lead to the decline in the quality of coal, such as sulphurisation, weathering and other phenomena, so it is necessary to ensure the quality of coal by strengthening the safety management of the coal bunker. Improve the eco...

What are the applications of higher-order hyperstatic structure in architecture?

图片
  The application of higher-order hyperstatic structure in construction is very wide, mainly because it has the characteristics of excess constraint, geometric invariance, complex force state, various structural forms, good stability and strong adjustment ability, etc., which can satisfy the high requirements of modern construction for structural stability, load carrying capacity and safety. The following are some specific application examples: I. Bridge engineering Bridges are one of the important fields for the application of high superstatic structures. Through the use of higher-order hyperstatic structure, the stability and bearing capacity of the bridge can be increased, so that it can withstand larger loads and deformation. III. large-span building Large-span buildings are also an important field for the application of high superstatic structures. With the continuous development of modern construction technology, people's demand for building space is getting bigger and bigger...
