Industrial frames (industrial shed) are used as one or more spans, and typically one floor with sloping roof to cover large spans in industrial factories, agriculture, warehouses, repair shops, etc. In the not so\u00a0far\u00a0years, truss structures were used to cover large spans in the buildings.<\/span><\/p>\n Today, however, the use of frames (industrial shed) with variable cross section and moment joints in the manufacture of industrial metal structures is very common. The use of variable-gradient members in sloping industrial frames allows that places with a greater flexural anchor to have more inertia moments and therefore a larger cross-sectional basis. The cross-section of industrial frames is generally in the form of “I”, in which the dimensions of the wing along a member is fixed but of the height of the web are considered, depending on the size of the variable member’s bending anchor.<\/span><\/p>\n Industrial frames with variable section are also called\u00a0shed that in our country there are several factories that calculate, design and execute industrial frames in the form of shed for various spans. Due to the progress of the welding technology, most joints in the making\u00a0shed factories are carried out in the form of weld, and mainly the assembly and execution of the industrial shed in the used location\u00a0by screw joints are considered.<\/span><\/p>\n Determinant factors in the weight of industrial structures<\/strong><\/span><\/p>\n The area in order to\u00a0build the industrial shed is due to the rate of\u00a0the wind speed, as well as the maximum amount of\u00a0snowfall, the span of the hall, the height of the columns<\/span><\/p>\n Economizing any order is actually, knowing the actual size of the mentioned\u00a0dimensions and predicting requirements. Obviously, the best computations without considering the quality of welding, the use of bolts and nuts, and other standard joints, de-rusting and scientific\u00a0coloring, or the proper application of the components, will be lacked\u00a0the necessary\u00a0strength\u00a0and effectiveness. It needs to be explained that all manufactured parts of the company have been using a multi-year experience and constant monitoring, automatic submerged arc welding and the use of a fully standard material that can be seen at any time by the employer and has been approved by dozens of consulting firms and the monitoring device.<\/span><\/p>\n Basic information required for the design of\u00a0industrial structures<\/strong><\/span><\/p>\n Sloped Frame of the Industrial Shed<\/strong><\/span><\/p>\n The steel frame system plays a main role in bearing various live loads, snow, load, earthquakes and crane loads in industrial buildings. The steel frame system usually consists of members with variable cross-section and rigid-connections (rigid connection). These members are jointly under the influence of\u00a0the by axial force, shear force and bending moments, which are:<\/span><\/p>\n Loads on the roof\u00a0of industrial buildings is tolerated by layers and shifted to the steep main frames. Layers are designed and implemented in the form of beams with simple or longitudinal spans equal to the distance\u00a0of the frames throughout the hall or as continuous beams. The layers section is “I” shaped. It is recommended that the maximum allowed displacement of the layers due to the sum of dead loads and snow superimposed load is less than 1\/200 of the length of the crater.<\/span><\/p>\n To prevent lateral torsional\u00a0buckling of the main frame beams, they should be properly arranged to hold their compression flange at necessary intervals and alongside the side of the frame plate.<\/span><\/p>\n Anchor rod of the industrial shed<\/strong><\/span><\/p>\n Anchor rod of the industrial shed connects the width of the layers at certain intervals. The anchor rods, which are perpendicular along the layers in the sloping frame roof, play three important tasks:<\/span><\/p>\n Industrial shed building because of its largely industrial application in terms of design is different with other structures, especially the frames are completely different in these types of structures and have slopes, and the spans are also larger than other structures. Due to the large dimensions of the beams and columns, it is not possible to use the profiles existing in the market for the construction of this structure and they should be constructed, which is called the plate girder.<\/span><\/p>\n The design of\u00a0industrial\u00a0shed<\/strong><\/span><\/p>\n The designing of industrial\u00a0shed is specialized and highly accurate, important factors are\u00a0involved in design, which can inevitably impose a significant cost on the constructor, which question the economic cost and may also reverse the opposite result and undermine the strength and stability of the structure. . For the design of industrial\u00a0sheds, software called Soole Pardaz (SAP) is used. Using this program, a bridge crane, bearing cranes and foundations can be designed. The following information is desirable to design an industrial\u00a0shed:<\/span><\/p>\n By knowing the above information and the intended dimensions for the industrial\u00a0shed, we attempt to\u00a0design it, which will eventually become the working drawing and implementation\u00a0of the structure, but the implementation of the structure of the industrial\u00a0shed is seemingly easy but in the back is hard, and there are certain engineering teams that execute the industrial\u00a0shed. Assembly, alignment and adjustment of the frames of the industrial\u00a0shed are a very sensitive work, keep in mind that the sidewall braces are implemented quickly and at the same time\u00a0because one of the weaknesses of the industrial\u00a0shed structure is its weakness of stability against lateral forces, which is, of course, completely restrained by the side guards But its execution time is significantly important.<\/span><\/p>\n Cutting and drilling the industrial shed<\/strong><\/span><\/p>\n Before making various components of the industrial shed, by using the\u00a0build\u00a0order plans (SHOP DRAWING) plate is cut by the guillotine (iron scissors) in the workshop,\u00a0 and then assembled and welded, the necessary drilling is done at this stage as well.<\/span><\/p>\n Confirmation and color of industrial shed<\/strong><\/span><\/p>\n Before painting, parts are checked and approved by the engineers and sent to the sandblast if needed, and are ready to be painted after cleaning. At this stage, two or three layers of paint are applied to the columns and the girders and other metal components, in which the number of layers and type of paint are available in specifications and drawings.<\/span><\/p>\n Painting with brush is not allowed and should be painted with pistol.<\/span><\/p>\n Sandblast is said to be operational, during which the silica sand is sprayed with pressure on the piece to prepare the surface for painting, in addition to clean-up\u00a0rustiness. Usually, all metal parts are sandblast before painting. An important point in Sandblast’s operation is that it should be avoid from exaggerated at this work, because it will cause erosion and thinning of metal layers.<\/span><\/p>\n Transportation\u00a0and installation of\u00a0industrial shed<\/strong><\/span><\/p>\n After painting, the stage is transportation and installation of the industrial shed that the built parts are transported from the construction location (workshop) to the place of installation (the buyer’s land) and the installer’s unit for the installation of the industrial shed is dispatched to the site. The installation is carried out by heavy cranes. At this stage, it must pay attention that the frame must be installed completely, because due to the height of the columns, if the rafters are not installed and installing the columns individually and dropping out them, there is\u00a0the possibility of\u00a0a reversal\u00a0of the column.<\/span><\/p>\n Computational\u00a0loads of industrial shed<\/strong><\/span><\/p>\n The loads loaded on an industrial building include the following, which should be calculated according to the recommendations of valid\u00a0regulations and applied appropriately to the industrial frame. The dead load of the industrial shed includes the weight of the various parts of the frame, roof coverings, glass wool and chicken wire.<\/span><\/p>\n Snow load of the industrial shed<\/strong><\/span><\/p>\n According to the geographical location and the location of the industrial frame, in terms of the amount of snowfall, wind and slope of the industrial roof, the loads from snow on\u00a0the frame are determined and applied to the frame.<\/span><\/p>\n Wind\u00a0load of the industrial shed<\/strong><\/span><\/p>\n The load caused by the wind blows horizontally and sideways along the main axis of the industrial building.<\/span><\/p>\n Earthquake load of the industrial shed<\/strong><\/span><\/p>\n The earthquake load should also be determined according to the proposed\u00a0relationships of loading regulations and applied appropriately and horizontally on the industrial frame. The earthquake force is a function of the weight of the structure, the coefficient of frame loading of the structure and etc.<\/span><\/p>\n Crane load of the industrial shed<\/strong><\/span><\/p>\n In some industrial buildings, cranes are installed to move heavy objects in the longitudinal and transverse directions of the hall. The main bridge and crane rails should be designed for the most critical type of loading.<\/span><\/p>\n Advantages of the industrial shed<\/strong><\/span><\/p>\n Ability to implement structures of various s<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" Industrial Shed Industrial frames (industrial shed) are used as one or more spans, and typically one floor with sloping roof<\/p>\n","protected":false},"author":1,"featured_media":6670,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[306],"tags":[],"yoast_head":"\n\n
