The Importance of Foundation Design for Steel Silo Stability

-
图片
  The foundation of an industrial steel silo is its unsung hero—while the silo’s steel structure is visible and often the focus of attention, the foundation bears the entire weight of the silo and its stored materials. A poorly designed or constructed foundation is the leading cause of steel silo instability, leading to issues like uneven settlement, tilting, wall bending, and even structural collapse. For project contractors, facility owners, and engineers, prioritizing foundation design is not just a construction requirement; it’s a critical step in ensuring the long-term safety, stability, and durability of steel silo projects. Steel silos are unique in their load requirements—they carry heavy, concentrated loads (often thousands of tons of bulk materials like coal, cement, or ores) and are often exposed to external stresses like wind, snow, and seismic activity. Unlike other industrial structures, a steel silo’s foundation must distribute these loads evenly across the soil to a...

Quality control of space frame processing

-

 The quality control of the space frame processing process is mainly reflected in the following aspects:

1. Special technical disclosure. Before each type of component grid processing, the project must be disclosed: grid processing quantity, completion time and requirements, acceptance standards, problems to be paid attention to in construction, technical assurance measures, protection measures for finished products and semi-finished products, possible accidents and measures, welding by material and welding process parameters, welding sequence, etc.

2. Measurement control. Measurement control runs through the whole process of grid processing, from the inspection of material size, cutting size inspection, component group deviation, component welding Angle size, correction deviation control, pre-assembly size, drilling aperture, paint film thickness and so on. In order to ensure the accuracy of measuring instruments, the use, storage, maintenance and inspection of measuring instruments are required to be carried out in accordance with the provisions.



3, cutting and cutting stage quality control. The quality inspection personnel first obtains the cutting sheet from the technical personnel, and reviews the size and material of the cutting sheet according to the construction drawings. If there is any mistake, it will be fed back to the technical person in charge for scrapping. Secondly, it is to check the actual drawing size, size and material of the construction team after cutting; If it is not correct, it will be fed back to the person in charge of cutting, redrawing the line and cutting the material. Finally, check whether the cutting size is correct according to the allowable deviation of the technical disclosure, and fill in the record.

4, H-shaped steel group stage. Wrong side control: t/10, and not more than 2 mm, ￡is the thickness of the steel plate. Section size control: including height, perpendicularity, center shift. The verticality control of the flange plate to the web plate: b/100, and not more than 2mm, 6 is the width of the H-shaped steel flange. Group on gap control, etc.

H-shaped steel parts splicing requirements, flange plate splicing seam and web joint spacing should not be less than 200mm, flange plate splicing length should not be less than 2 times the width of the plate, web splicing should not be less than 300mm, the width direction is best not splicing.

5, welding stage. Including weld root cleaning inspection (for penetration weld), weld appearance inspection, weld size inspection.

6. Correct cutting. Calibration stage is mainly verticality, distortion detection, qualified into the next process cutting.

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 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...

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...
