Q:What are the types of steel structures?
Under the condition of complex large-scale, large span, tall, deep, light and modern facilities building design theory, construction technology and reinforcement technology research and optimization method of structure safety and durability evaluation and maintenance of engineering structure and improve the research capacity of disaster prevention and mitigation of the various ways and methods, with the help of the computer science, material science, testing technology and with the application of new theories, new technologies, new materials, new technology, engineering structure of ancient discipline is developing rapidly.
Q:How to detect crack of steel structure quickly and effectively
Cracks are generally observed on the weld or on the surface of the component. Large cracks can be seen with the eye, but there is often a capillary crack near the big crack. This is not necessarily an eye view, but these cracks can be detected with magnetic particle inspection
Q:The meaning of UT in steel structure
Ultrasonic testing (ultrasonic, testing). The use of an object's own or defect's acoustic characteristics to detect the effects of ultrasonic propagation on object defects or certain physical characteristics. The ultrasonic frequency used in ultrasonic testing is between 0.5 and 5 MHz (MHz). The most commonly used ultrasonic test is pulse flaw detection
Q:What does the title of a steel structure mean?
A support beam structure consisting of bars welded, riveted, or bolted, called a truss". The advantage of the truss is that the rod is mainly subjected to tension or pressure, which can give full play to the role of materials, save materials and reduce structural weight. Commonly used are steel truss, reinforced concrete truss, prestressed concrete truss, wood truss, steel and wood composite truss, steel and concrete composite truss
Q:What are the budgets for fire-resistant coatings for steel structures?
Fire resistance grade 2.5 hours, paint should be painted to 3mm. General again brush up 1.3mm thick and material price in Xi'an area with artificial material does not contain measures fee at 55 yuan / square meters of brush, but not regular professional fire, professional fire can meet the design requirements with the price will be twice as expensive as about 100 yuan.
Q:I want to make light steel structure. What tools do I need?
Another major content of the construction of steel structure is welding. The field welding equipment is mainly manual welding. As the labor costs are increasing day by day, in order to improve the efficiency, the gas shielded welding is becoming more and more popular at the installation site. Welding auxiliary equipment is the drying equipment of welding rod: drying machine.
Q:What is a light portal steel frame?
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.
Q:Steel plate for steel structure, what kind of steel plate is it
The grades of carbon structural steel are composed of four parts: the yield strength, the letter Q, the yield strength value, the quality grade mark (ABCD), and the deoxidation method notation (FZTZ).
Q:What is the difference between steel structure and iron art?
A material with high strength and light weightThe strength of the steel is high and the modulus of elasticity is high. Compared with the concrete and wood density and the ratio of yield strength is relatively low, and therefore under the same loading conditions section of steel structure is small, light weight, convenient transportation and installation, suitable for large span, height, weight bearing structure.Two, steel toughness, good plasticity, uniform material, high structural reliabilityThe utility model is suitable for shock and dynamic loads and has good seismic performance. The microstructure of the steel is uniform and almost isotropic. The actual work performance of the steel structure is in line with the calculation theory. Therefore, the reliability of the steel structure is high.Steel structure manufacture and installation of a high degree of mechanizationSteel structural components are easy to be fabricated in factories and assembled on site. The mechanical manufacture of steel structural parts in the factory has the advantages of high precision, high production efficiency, rapid assembly site and short construction period. Steel structure is the highest degree of industrialization of a structure.4, iron art:The main methods for removing rust and removing oxide welding slag are manual processing, mechanical treatment, jet treatment, chemical treatment (acid washing), electrochemical treatment and flame treatment.Two, for iron products, except for the general use of organic solution, lye, electrochemistry and other methods, is now available in the market for a variety of metal cleaning agent is also more applicable.
Q:How can steel structures be divided into general steel structures, large steel structures and other steel structures?
There is no standard and strict definition of steel structure division.
