Coastal Steel Roof Projects: Waterproofing and Anti-Corrosion Methods

-
图片
Coastal areas bring unique challenges to steel roof structures, with high salt spray, humid air, strong winds, and heavy rainfall accelerating corrosion and leakage. These issues shorten service life, increase maintenance costs, and pose potential safety hazards. For large-span steel roof projects in coastal regions, scientific waterproofing and anti-corrosion measures must be integrated into material selection, construction, and daily maintenance to ensure long-term stability. Below are concise, practical solutions for these two core issues. Anti-Corrosion Strategies: Combating Salt Spray and Humidity Salt spray is the main cause of steel corrosion in coastal areas, as chloride ions penetrate coatings and damage steel structures. Effective anti-corrosion depends on a multi-layer protection system combining high-quality materials and optimized construction. 1. Anti-Corrosion Material Selection Opt for high-performance anti-corrosion steel plates instead of ordinary galvanized ones,...

What are the characteristics of the space frame structure

-

space frame roof


  1. The space frame is a mesh structure composed of many steel bar. It is a high -end super -static space structure. The space frame structure can be divided into two types: flat space frame and curved space frame.
  2. The flat space frame is used more. The advantages are: space stress system, the pole parts are mainly axial force, reasonable force, good overall performance, large rigidity, and good shock resistance. There are fewer rod types, suitable for industrial production.
  3. Space frame can be divided into two types: cross truss system and corner cone system. The corner cone system is more reasonable and greater.
  4. The height and short -span of the space frame is generally about 1/15. Steel tubes are generally used, and nodes generally use ball nodes.

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...

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

  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...

 It is widely used in modernist architecture. Steel structure installation is mainly carried out by electric welding welding and bolts. Because the steel frame structure is compact and practical, it brings great convenience to engineering construction. In order to promote the sustainable development concept of steel frame structure in the construction engineering industry, it is necessary to carry out an in-depth analysis of the construction stage of steel structure, especially the node design, to ensure reliability.       Steel plate materials are widely used in modernist buildings because of their extreme seismic performance, plasticity and reliability. Jiangsu steel structure project construction is to be processed with bolts or steel to make the building structure. Accompanied by the improvement of living standards and the rapid development of the construction industry, the requirements for steel frame structure are rigorous. As a result, the design of steel fra...
