Hello everyone, today to introduce structural steel is on understanding the most important articles today is the use of structural steel to understand what some of these species so we can literally know the structure of the steel used in the structure above is actually like building structure or some machine quit it plays the most important role is to support the use of structural steel so it is particularly important if the skeleton is good with basically a whole is not a big problem if the structure if no contrary may well be a problem here, you might think it is sometimes the use of structural steel materials there would be no problem? this is not necessarily the choice depends on what kind of structural steel used in what situations would be more suitable so today will look at what some of the uses of structural steel is probably the where structural steel is kind of how it produces the most important is the use of the materials used in the proper place so it can save more weight materials, etc. but can also be obtained relative strength is good so use this to produce its characteristic structure is used up the first is the solid angle iron angle iron class class we can broadly be divided into two categories first equilateral triangle is equilateral triangle another so literally can know one another on both sides of equal length on both sides is unequal so long angle iron is very often used in life like some heavy angle iron like what you'll see some of shelving is made of angle iron angle iron structure with racks so that it can carry the power of a very big difference that said angle iron side might be doing some of punching part can be fixed or do some actually do welding structural steel can be so used drilling, punching, cutting, or milling, and so do the processing or welding it is possible to see how we use it to put it another angle iron can imagine it's like a flat sheet metal folding action of gold in the side do not underestimate us once this entire hem hem gold plate will be changed for the better is the strength of this mode of thinking to imagine so when the height of the higher relative strength hem gold plate the better as this will generally support the use of force in this direction characteristic angle iron reinforcing sometimes do see something like air-conditioners sometimes this angle iron reinforcing or supporting party is doing some place to do may be more elongated bearing surface where it will do the triangle reinforced with angle iron which is also a way to use here to let everyone know Hello to introduce at the next class is actually iron pipe iron pipe class and we are often seen like this in the form of square tube square tube sometimes see the opposite course of iron pipe furniture are relatively small wall furniture thick or too thin a bit like a rectangular tube furniture, iron chairs will see even square tube, rectangular tube or pipe bend sometimes do it is through a bending action bending mold bender so sometimes it bends out of shape to do some special course, such changes will have a corner after elbow R is also possible to additionally relatively large pipe we'll see some type of tube like it may have run a number of gas Some, like the larger body or gas oil, etc. are likely to see these classes form the main tube to see the iron pipe wall thickness relative to the general class may be seen that it will be relatively thin construction like sometimes the main structural steel class it is possible to see these iron pipe less likely to use these classes where not so good like stairs strength might be used later in a minute if you want to support better will explain another structure next to introduce steel H-beam is actually kind of like the word iron, I-beam, etc. its forms are so similar are similar to H or I shape so let's see H-beam actually see most often where did or sometimes like to see some kind of bridge construction will see this type of H-beam H-beam so in buildings, bridges and so on such a large class of non often see this kind of support you may sometimes say will be used in addition to the use of architectural else if it is in fact the iron inside the factory may also see just you do not have to notice what is it? If you think about the fact you need to hang inside an iron factory very heavy object is what you would expect if you have to pay attention to the crane, then sometimes crane main structure is made of H-beam H-beam can support a very large force of H-beam combination in several ways sometimes see it can make hole and then lock the side very much attached screws or welding is done directly say these two are likely in fact we do not necessarily like the H-beam is only used in the construction crane or if can use in mechanical structure actually to see how we can be of use to it and even used in the H-shaped steel molds, jigs, etc. are also the base can even make it into work tables is no problem here to see how you make use of it here Hello everyone look next to introduce slot is a slot ferrous iron is another relatively similar or like light gauge steel C-shaped steel, U steel, etc. can be collectively referred to this kind of divided into two main one is relatively light the amount of its relatively thin wall thickness of relatively small size may be a little too big of course, some of these are more often we will use it like water and electricity where sometimes doing some line or side line integration time might even do a lot of holes will be hanging above the ceiling line and we'll do the whole use light gauge steel since the entire line is very easy to line it can collect on the inside or the whole beautiful finishing and so will become more convenient addition One is the trough of iron tank iron it is a relatively heavy use may more often we will do it in a groove like iron base mode of governance or some large machinery main base is also possible to use a lock attached by soldering are likely or do some of the fixed and so we are likely to use this type of structure is the most important because it is relatively strong as you can use it here as this place it highly as before just have to mention it is the use of angle steel angle iron class the hem like sheet metal folding means Here iron groove is the same reason just iron groove thickness will be thicker side relative intensities may be better to do the same number of punching or milling off may be even above the tapping attachment lock no problem to summarize the final in fact, knowledge articles about steel structure introduced after these types of structural steel we need to know what is fact, not necessarily what the industry must use this structure is not necessarily just seeing these structural steel in fact, it has some characteristics of it to use in like the case of the main architectural framework may be more suitable for use in steel houses word like iron, H beam, if that is more appropriate square tube, rectangular tube, pipe angles and even, as it will be less suitable for edge strength is relatively much worse is the use of course, if the entire line if used in hydroelectric H-beam seems to be too heavy with light it may be no problem if the steel is to use a heavy-duty rack if used like groove iron, then, of course, the relative structure is very solid, but seems to be too heavy turn out to be an overly strong design strength is too strong to use them if the use of angle iron angle iron is more than enough if not necessarily to use the comparison of course you can use other strong way to make it more robust is not a problem but we can choose a more suitable like furniture generally lightweight iron pipe would be more appropriate if the furniture is the use of H-shaped steel was too heavy so too is the use of the occasion to of course, the choice of suitable structural steel structural steel can do something with the use of use may sometimes be interspersed they might use some iron pipe in H-shaped steel which of course is the main support of H-beam and this is not a problem to see how you utilize it with the use of La Teaching today went to the far side we look forward to the next teaching it Bye ~
