What is a light portal steel frame?
Plasticity and toughness are good. Steel has good plasticity. The steel structure will not happen sudden damage in general, but it will be marked by a larger deformation in advance. In addition, the steel has good toughness and can withstand the dynamic load well. All these provide a reliable guarantee for the safety of the application of steel structure.High degree of industrialization - steel structure is made of various kinds of materials (I-beam, channel steel, angle steel) and steel plate. Through the cutting, welding and other processes, the steel component is manufactured, and then the site is installed. The general steel structure can be used in the metal structure factory with a high degree of mechanization and specialized production. Therefore, it has high precision and short manufacturing cycle. Due to the assembly operation, the installation efficiency is high and the construction period is short.Demolition convenience - steel structure due to high strength, it is suitable for the construction of light weight, easy to connect structures can be removed.
Light steel structure is made of steel (steel plate and shaped steel), and compared with other materials, the steel structure has the following characteristics:High strength steel strength and elastic modulus of concrete, masonry and wood to be many times higher, due to the small weight, high stiffness, steel structure for the construction of large span and super high and super heavy buildings especially suitable for.Small weight - the weight of ordinary steel roof truss only reinforced concrete roof truss 1/4~1/3, if the use of thin-walled steel roof, it is lighter. Because of its light weight, the steel structure is also convenient for transportation and lifting, and can lighten the burden of the substructure and the foundation.Uniform material - the internal structure of the steel is uniform, very close to the isotropic body, and in a certain range of stress, it belongs to the ideal elastic work, and accords with the basic assumption adopted in engineering mechanics. Therefore, the calculation method of steel structure can be accurate and reliable according to the principle of mechanics.
The light portal frame is also called the light portal frame structure"The light portal frame structure is mainly refers to: the bearing structure for single or multi span portal frame, with light roof and light wall, can set up the weight of not more than 20t, light duty suspension crane bridge crane or 3T monolayer steel structure workshop.
