How to Choose Roofing Materials for Steel Structure Buildings

-
图片
  Steel structures are a top choice for industrial, commercial and partial residential construction, thanks to their lightweight design, high strength, fast construction and flexible layout. The roof, as the core protective layer of steel structure buildings, directly affects the waterproofing, heat insulation, energy efficiency and service life of the whole building. Different from traditional concrete structures, the roofing materials of steel structures must fit the structural characteristics of light weight and good ductility, and also take into account wind resistance, corrosion resistance and construction convenience. Selecting roofing materials for steel structures is never a simple choice based on price, but a comprehensive decision combining local climate, building function, budget scale and later maintenance needs. This guide sorts out the core functional categories of steel structure roofing materials, with clear analysis of their advantages, disadvantages and applicabl...

What is the size of the grid size depends on?

space frame

Grid size depends on the choice of roofing materials, 

  1. if the roofing system without purlins, that is, the use of wire mesh cement board or reinforced concrete roof panels, grid size should not exceed 4m, otherwise the roof panels will be very heavy;
  2. If the purlin system is used, the grid size should not exceed 6m due to the economic span of purlins.

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...
