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 ...

How are space frame structures applied in industrial buildings?

-
 In the rapid advancement of modern industry, industrial buildings serve as the core spaces for production and storage. Their structural design must not only fulfil functional requirements but also balance safety, economy, efficiency, and sustainability. As a company consistently focused on environmental stewardship and dedicated to providing high-quality, safe, and robust steel structure designs and products globally, we recognise that space frame structures represent the ideal solution for achieving these comprehensive objectives in industrial building applications.

Space frame structures comprise spatial grid systems formed by multiple members connected through nodes. Their unique load-bearing characteristics and geometric configurations offer exceptional advantages in industrial building construction:

Achieving Extraordinary Spans: Industrial facilities frequently require expansive, column-free spaces to accommodate production line layouts, large-scale equipment installation, or efficient warehousing. Space frame structures effortlessly achieve spans of tens or even hundreds of metres, providing clients with exceptionally flexible internal spaces that significantly enhance site utilisation and production efficiency.

Lightweight, efficient, and cost-effective: Through rational mechanical load distribution, space frames disperse loads across multiple members, resulting in low self-weight and reduced steel consumption. This not only lowers foundation costs and shortens construction timelines but also delivers substantial economic benefits to owners.

Flexible Form, Adaptable Design: Truss structures can be customised into various configurations—such as flat-plate or spherical-shell trusses—to accommodate complex floor plans and roof profiles, imparting a contemporary aesthetic and architectural value to industrial facilities.

Convenient construction with controllable timelines: Truss components can be prefabricated in factories, assembled on-site at elevated or ground levels, and then lifted into position as a unified structure. This industrialised construction approach substantially enhances efficiency, shortens project timelines, and ensures timely delivery.

As a steel structure company committed to green and environmentally friendly principles, we integrate this core value into every aspect of our space frame industrial buildings:

Efficient material utilisation, minimising waste: Through advanced BIM technology and precise structural analysis, we optimise space frame design schemes to ensure every member and connection point achieves maximum efficacy. This enables precise steel quantity control and efficient utilisation, reducing resource wastage at source. As a renewable material, steel is 100% recyclable, significantly lowering consumption of natural resources.

Enhanced Building Energy Efficiency and Green Operation: The large-span characteristics of space frame structures provide ample natural lighting and ventilation for industrial buildings, reducing reliance on artificial lighting and air conditioning, thereby lowering operational energy consumption. We can further integrate green technologies such as roof insulation materials and solar photovoltaic panels to enhance the overall energy efficiency of the facility.

Durable and Low-Maintenance: Utilising premium steel combined with advanced anti-corrosion coating techniques (such as hot-dip galvanising and heavy-duty anti-corrosion coatings), we ensure truss structures maintain exceptional longevity even in demanding industrial environments. This minimises long-term maintenance requirements and resource consumption, realising the building's full lifecycle green value.

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...

Suspension structures

-
图片
 A suspension structure is a structural form that carries roof loads through a series of high-strength steel cables. Its main load-bearing member is the cables, which are usually steel cables made of high-strength steel wires. The roof of the suspension structure is generally light and thin, and its shape can be very flexible, able to realize the large span across. For example, in the roofs of some large conference centers or exhibition halls, the suspension structure can create unique shapes such as double-curved paraboloid or single-curved paraboloid, which make the building have a strong artistic influence. Suspension structures require a stable support structure to anchor the steel cables, usually using reinforced concrete columns or steel columns as support. And in order to ensure the stability of the structure, it is also necessary to set a certain amount of prestressing, so that the steel cables are in a tensioned state before they are subjected to loads. Scope of applicatio...

What is the difference between a single-layer reticulated shell and a double-layerreticulated shell?

-
图片
  The differences between single-layer reticulated shells and double-layer reticulated shells are as follows: Structural Configuration   Single-layer reticulated shell: Composed of a single layer of members, with the members directly connected to form a grid structure . The node configuration is relatively simple, typically employing rigid connections that allow the members to bear not only axial forces but also bending moments and shear forces.   Double-layer reticulated shell: Consists of upper and lower parallel layers of members connected by web members, forming a truss-like structural system. The nodes are generally hinged, and the members primarily bear axial forces. Its configuration is relatively complex, requiring more members and nodes to ensure structural stability and load-bearing capacity. Structure Single-layer mesh shell: composed of one layer of rods, the rods are directly connected to form a mesh structure, the node structure is relatively simple, usually...
