Among the most common construction methods in the country, we can mention concrete frame and metal frame structures.\u00a0 Each of these methods has its own merits and advantages.\u00a0 Metal skeleton is used more because of its high execution speed.\u00a0 If you also want to build your building with a metal frame, it is better to familiarize yourself with its steps.\u00a0 In the construction of each structure, certain steps must be followed and certain principles and rules must be fully observed.\u00a0 In the construction of metal framework, there are specific steps that any structure that is going to be built in this way must go through these steps step by step.<\/p>\n

Project planning, control and management<\/strong><\/h2>\n

\"Project<\/p>\n

Each project has several implementation stages, each of which can have special challenges.\u00a0 Before starting the project implementation, the project manager identifies the upcoming challenges and plans to achieve the goals within a certain period of time.\u00a0 The monitoring of each project in all its stages is the responsibility of the project manager.<\/p>\n

The project control unit prepares the daily, weekly and monthly report of each project in written form.\u00a0 If the project is delayed, its causes will be investigated.\u00a0 Then, the causes of the delay and its compensation solutions are communicated to the project management in order to make a decision.<\/p>\n

Surveying<\/strong><\/h3>\n

The compliance of accuracy and quality in construction with project conditions is checked by surveying.\u00a0 First, the dimensions of the project land and the separation joint \u00a0are taken.\u00a0 Then, the location of the bolts connecting the foundation to the column plate is controlled before concreting.\u00a0 After the completion of concreting, the bolts are accurately mapped and possible effective modifications in the structure are communicated to the modeling team, and the drawing shop model is completed then corrected based on the last communicated surveying.<\/p>\n

In the final stage, the verticality of the sections and the exact axis of the columns during installation are determined by surveying.\u00a0 This increases the accuracy of construction and installation of the structure, which shows the importance of surveying in the project.<\/p>\n

Supply of consumables, ironware and bolts<\/strong><\/h3>\n

The quality of material used in steel structures plays an important role in the accuracy of construction and installation of the structure.\u00a0 The use of high-quality steel raw materials at a reasonable price requires the experience of obtaining up-to-date information from the iron and steel market.\u00a0 On the other hand, the quality control team carefully examines the raw materials and manufactured products of the factory, and the products are delivered to the warehouse after approval.<\/p>\n

Inventory Management<\/strong><\/h3>\n

Raw materials entering the factory and parts ready to be delivered to the project are recorded by the inventory unit.\u00a0 Preparation of detailed input list and packing list related to factory output products is one of the services of warehousing unit.<\/p>\n

Cutting<\/strong><\/h3>\n

The raw materials entering the factory first enter the cutting section.\u00a0 Initial cuts are made based on single part drawings.\u00a0 Cutting machines cut the parts in two hot and cold ways.\u00a0 It should be noted that the type of cutting (hot or cold) is determined according to the regulations that depend on the thickness of the steel sheet.\u00a0 In hot cutting, steel sheet or profile is cut with the help of melting process.\u00a0 If the regulations permit cold cutting for a sheet, devices such as cutting scissors, punches, circular saws and belts can be used.\u00a0<\/strong><\/p>\n

The stages of cutting, strapping and drilling<\/strong><\/h3>\n

Complicated and uncomplicated parts are produced with the help of hot and cold cutting machines.\u00a0 Then the production belts and other parts are assembled next to each other and are ready for welding according to the location of the welding straps in the part.<\/p>\n

\u00a0Some parts are cut and drilled according to the mapping and templates sent from the project.\u00a0 This is necessary for accurate and quality installation of structural elements.<\/p>\n

Dimensional Control<\/strong><\/h3>\n

The dimensions of the parts are checked before assembly.\u00a0 In case of defects or inconsistency of the parts with their execution plans, they are corrected.\u00a0 In the next step, they are sent to the assembly and welding department.<\/p>\n

Assembling the columns in the Rooyesh metal industry factory<\/strong><\/h3>\n

The columns produced in the factory include three types of H-shaped, Box and HSS.\u00a0 HSS parts enter the factory in the form of ready-made single-seam boxes.\u00a0 Therefore, there is no operation for their construction, which increases the construction speed in the column section.\u00a0 Box-shaped columns are first made in U-shape.\u00a0 Then the restraining rods are placed in it as a support for the column flange and the pillar.\u00a0 If a stiffening plate is needed inside the column, at this stage, the stiffening plate is welded in the column, and in the last step, the second life of the column is connected to the U-shaped piece by welding.\u00a0 The belts related to the H-shaped elements are also placed next to each other by the H-shaped machine with spot welding.<\/p>\n

Assembling plate girder in Rooyesh metal industry factory<\/strong><\/h3>\n

The girders are also assembled in the H-shaped machine after strapping, just like the H-shaped columns.\u00a0 It should be noted that the H or I-shaped sections available in the hardware market have limited dimensions.\u00a0 Therefore, if the desired dimensions of the project are not available in the market, that element is made in the factory.<\/p>\n

Welding in Rooyesh metal industry factory<\/strong><\/h3>\n

The parts assembled in the factory are sent to the welding place.\u00a0 Single gate submersible welding machines and gas shielded welding are used by skilled welders for the final welding of structural elements.<\/p>\n

Welding machine with gas shield<\/strong><\/h3>\n

In some elements where there is a need for finesse for welding or the welding nozzle must be placed inside the section, it is suggested to use gas shielded welding.\u00a0 The gas used in this device, including argon or CO2 gas, prevents the weld from reacting with the surrounding air.<\/p>\n

Bailing<\/strong><\/h3>\n

Production parts need to be painted according to regulations and structural drawings before being sent to the project site.\u00a0 In order to paint without any defects, the parts are bailed first.\u00a0 Bailing includes removing rust, corrosion and other contamination by wire brush, sandblasting or pressure shot blasting.\u00a0 After the completion of the cleaning stage, the elements quickly go to the painting stage.<\/p>\n

Painting<\/strong><\/h3>\n

The 10th<\/sup> topic of the National Building Regulations considers painting for steel elements as essential, except in cases where the supervisor or regulations do not allow painting, and one of these cases is a part of the steel elements that is placed in concrete.\u00a0 In the aforementioned regulations, the thickness of the paint and the type of paint used for steel elements are determined according to the environmental conditions.\u00a0 Some types of paint commonly used in painting metal parts include zinc chromate, zinc rich, alkyd and epoxy.<\/p>\n

Straightening plate girder sections with the H straightener machine<\/strong><\/h3>\n

Continuous welding on both sides of the connection to the flange of the I or H-shaped section causes thermal stress and there is a possibility of deformation in the element.\u00a0 The smoothing machine H corrects existing deformations with the help of cold rolling and rolling.<\/p>\n

Finishing<\/strong><\/h3>\n

At this stage, parts such as connections, gusset struts, handles connected to the column, splices, etc., which must be connected to the elements before sending the load to the workshop, are fixed by corner or penetration welding.<\/p>\n

Loading and transporting to the workshop<\/strong><\/h2>\n

The parts are ready to be delivered to the workshop after being painted and getting the final quality control approval.\u00a0 In order to speed up the implementation of the structure, the parts are prioritized and directed to the loading area.\u00a0 The prioritization of parts is based on the implementation conditions of the project, the path of the vehicle carrying the parts, the length of the part and the absence of traffic load.<\/p>\n

Conclusion<\/strong><\/h2>\n
