How to Fix and Prevent Roof Leakage in Light Steel Structures

-
图片
Roof leakage is one of the most common problems in light steel workshops and warehouses. It not only affects daily use but also causes internal corrosion, shortens the building’s service life, and leads to higher maintenance costs. Most leakage happens at panel joints, screw holes, flashing areas, or around openings. The main reasons are poor waterproof treatment, aging sealant, loose screws, or improper installation. To fix existing leaks, first clean the surface and locate the leakage points. Replace damaged or aging sealing strips. Re-tighten loose screws or replace them with waterproof self-drilling screws. Apply professional waterproof sealant at joints and openings. For serious cases, add a layer of waterproof coating to improve protection. To prevent future leakage, use high-quality roof panels and waterproof materials from the beginning. Ensure professional installation with standard flashing and sealing design. Conduct regular inspections, especially before rainy seasons, and ...

The economic benefits brought by steel structure

-

 "A new building system can open up the industry line between construction, metallurgy, machinery and equipment manufacturing, new building materials and disaster prevention and reduction industries, become a national strategic resource reserve, and integrate innovation into a strategic emerging industry." Steel structure houses are conducive to economic transformation and upgrading and sustainable development, and need to accelerate cultivation and development." This is a few years ago, the industry is generally optimistic about the steel structure building system.

Steel structure residential general system for residential use, with unique advantages, including: first, light weight. Steel structure housing can reduce the building weight of about 30%-25%, which is conducive to the construction of high-rise buildings, especially in places with low geological carrying capacity and high seismic intensity, and its comprehensive economic benefits are better than ordinary residential building systems. Secondly, the layout is flexible, the room is large, and the room type is rich, which can increase the construction area by 3%-25% to 5%-25%. Due to its full flexibility, modifiability and safety, it is conducive to meeting the needs of modern life. Third, it is easier to achieve industrialization, standardization, mass production, and improve the structure of the labor week.



Steel structure steel is facing the new challenges of the rapid development of China's steel structure industry, and the increasing amount of steel used in steel structure has also accelerated the production and research and development of steel used in steel structure. However, compared with developed countries, there are still many gaps:

The proportion of high-performance steel used in steel structures needs to be improved. In addition to the advantages of light weight, high strength, excellent material properties, high industrialization of production and installation, suitable disassembly, and good durability, building steel structure also has the characteristics of saving resources, reducing carbon emissions, recycling and so on. Therefore, the steel used in the steel structure also needs to be light in weight, high in strength and corrosion resistance. However, at present, some steel structure projects still have the defects of "stupid, heavy and large", and high-grade structural steel is needed to change the status quo. For example, carbon structural steel (Q235) can be replaced by low-alloy high-strength structural steel.

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?

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...
