Q:What angles, angles and channels are used in general? Please try to be specific?
Profiles are commonly used in construction for steel structures, plant buildings (single deck, multiple), adding (inserting) layers, and simple and independent components: Roofing frames, interior and exterior steel staircases, etc.In steel construction plants (buildings), what you call those profiles are useful
Q:Is the crane telescopic arm welded by channel steel or by square tube?
You think, is certainly the square and thick wall, to ensure the overall stiffness and strength.When the channel steel is welded together, how can the weld be treated? If the welded joint is too high, it will affect the expansion of the inner and outer walls Flat and can not, and it can not be welded inside, how to ensure that the intensity?In order to save money by not crane factory this rough steel welding method, and crane safety first, but once the problem is not trivial, does not rule out a small factory dare to do so, but definitely not the formal business.This kind of profile is formed at one time without any subsequent welding. It is a pressing forming sleeve with cold drawing technology!
Q:What are the methods and the price of building the floor?
Determine the function: attic building, must solve some practical problems, in order to meet the original building pattern can not meet the functional needs. Therefore, first of all, we should make clear the future use of the attic, and different functions have different requirements on the space. This has a direct impact on determining the scope and elevation of the attic building.
Q:What machine is used to bend the channel?
Specify the requirements for bending accuracy and whether there is any curvature change requirement. Does this decision require numerical control equipment?.
Q:How can theoretical weight be obtained for 12.5 channel steel?
Using 12.6# (126*53*5.5)Weight 12.37 m/kgTheoretical weight of channel steel W=0.00785* waist thickness [height +e (leg width waist thickness)]E value: the general model is 3.26The steel density is 7.85g/cm3
Q:What does channel specification "MQ-41" mean?
The raw material for producing channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
Q:Is outside building protection single row bent with cantilever steel instead of channel steel
JGJ130-2011 "construction of fastener type steel pipe scaffolding safety technical specifications" article 6.10.2 provides that cantilever steel beam applied biaxial symmetric steel, steel beam cross section shall not be less than 160mm.Therefore, the channel shall not be used (cross section asymmetry, cantilever bending, cross section is more likely to lose stability)
Q:Why did the channel steel start from the 4 floor?
Note: all cantilever channel wall must be done when the box, to prevent future channel can not be removed. There are cantilevered outer shelf, buried channel layer, for the cantilever channel construction, all the balcony on the side of the reserved steel bar, the latter two times pouring concrete. The other floors, outdoor lifts, discharging platforms and tower crane delivery platforms meet the same way on the top side of the balcony.
Q:Classification, use and material of channel steel
According to the channel shape and can be divided into 4 kinds: cold bending equilateral channels, cold-formed non equilateral channel steel, cold rolled edge channels, the cold bending edge channels.
Q:After the type of channel is not marked A or B, which shall be calculated?
For safety reasons, according to the A calculation, the weight of the material can be calculated according to B to avoid the insufficient use time
