How are space frame structures applied in industrial buildings?

-
图片
 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...

Inspection methods for welds

welding

There are several ways to inspect the weld as follows:
 
1. Visual inspection: inspection by observing the shape, colour, defects, etc. of the weld with the naked eye.
 
2. radiological inspection: the use of X-rays or γ-rays on the weld can detect defects within the weld, such as porosity, inclusions and so on.
 
3. ultrasonic inspection: the use of ultrasonic propagation characteristics, through the ultrasonic scanning of the weld to detect internal defects in the weld, such as inclusions, pores, cracks, etc..
 
4. Magnetic particle inspection: Coat the surface of the weld with magnetic powder and apply a magnetic field to detect cracks, inclusions and other defects on and near the surface of the weld.
 
5. Penetration inspection: Coat the surface of the weld with penetrant, and through the penetration and colour development of the penetrant, detect cracks, inclusions and other defects on the surface of the weld.
 
6. Magnetic Field Inspection: Detect defects in the interior and near surface of the weld by measuring the magnetic field distribution near the weld.
 
7. Acoustic Emission Inspection: Detect the acoustic emission signal of the weld by applying external force to the weld to judge the integrity and defects of the weld.

What is a coal bunker?

-

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

 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...
