Steel plant design three major issues that should be considered as a superiority steel industrial plant are summarized in the Summary section already mentioned the main advantages of steel industrial plant are: First, in terms of speed of construction: steel components can be factory production, steel building construction is simple, quick installation, greatly shorten the construction period; secondly, steel industrial plant in weight: the structural quality of buildings can reduce about 30%, especially in the foundation bearing capacity of low and high seismic fortification intensity place, its comprehensive economic than reinforced concrete structural system; and finally, from the environmental aspects: steel structures are environmentally friendly green building systems, steel itself is a kind of high strength and high performance materials with high recycling value, and does not require tooling. two construction, industrial plant for steel support system design principles in order to ensure that the work space Steel plant to improve its overall stiffness to withstand and transmit longitudinal horizontal force to prevent the rod excessive deformation, to avoid pressure pole instability, as well as ensure the overall stability of the structure should be based on the form of steel structure workshop, workshop crane setting span vibration equipment and plant height, length, etc. temperature zone arrangement of reliable support system. Each section of the plant should be set between temperature stable pillar support system, and with the roof transverse horizontal support coordination arrangement. Under the column support is an important factor in determining the location of the plant longitudinal direction of structural deformation and stress affect the size of the temperature, the lower column support as possible in the middle of the temperature zone, so that the crane beams of longitudinal members with more freedom to temperature changes to stretch to the ends of the section. When the length of the temperature zone is not, generally in the middle of setting a lower temperature zone column support, but the length of the temperature zone is greater than 150 meters, in order to ensure longitudinal stiffness of steel plant installation, the temperature should be within the zone Set the lower two support columns, its location should be arranged as far as possible within the scope of the section in the middle third of the temperature, in order to avoid excessive thermal stress, support center distance of not more than 72 meters two. Remedy steel fatigue damage such technical devices with small size, high frequency, can be used to facilitate the manufacture and assembly of steel bridge steel canopy characteristics, and therefore worthy of use in the production of steel bridges. Its top most used is tempered T arts, is about the overall component placed in a furnace heated, typically heated to 600 to 800. To overcome the above-mentioned process method and process measures of disadvantage in steel bridges in the development of a device known as a high-frequency ultrasonic impact technology. But when there is no input of energy to achieve the appropriate magnitude, reducing residual stress effect is not significant, and therefore, of course, currently used in the high-frequency excitation of the vibrator power supply technology has been very mature, and its small size, the higher frequency But it's the input energy is very low, so this can only be used under mature vibrator laboratory premise structural noise and vibration spectrum analysis. Because the standard of high frequency vibration table is limited, so not only for standard components using this method. In some metal processing and manufacturing, processing and assembly precision because some want more and more advanced components, reducing component residual stress, improve member service life demands more urgent, which has developed a technology called high-speed blasting, the effect is very Obviously, significant progress can be exhausted capacity and resistance to stress corrosion performance and get a wide range of applications. However, the frequency of hand-tap low, the energy input into the structure is limited, so the effect is not obvious. Difficulty of this approach is that, not only the structure of the weld zone in claim vibrator size, but also have to have a sufficient quality and high frequency vibration effect, since the input to the metal structure of the energy with the vibrator 43 actuator The quality and the role of the product is proportional to the square of the frequency. Because the overall average of the heating and cooling process structural deformation, so that the local high residual stress and strain to get loose. For large components, this method requires a large standard high temperature heating apparatus, therefore, can handle standard member heating means restricted actual device.
