Q:How heavy is channel 1, 16? How do you calculate the formula?
17.2Kg16# channel mass per unit is 17.2Kg, this often used by people remember, the formula is 17.2 x 1=17.2Kg
Q:Where does channel steel use more, Where does angle iron use more?
Hot rolled stainless steel ordinary channel (GB707-88) main use: ordinary channel steel, mainly used for building structures, vehicle manufacturing and other industrial structures, often with the use of i-beam.
Q:Span 6 meters, simple beam support center force 380Kg, need to choose how large channel steel, how to calculate?
Span 6 meters, simple beam support center force 380Kg, need to choose how large the calculation of channel:1, it is estimated that the weight of channel steel is approximately concentrated load;2, according to carrying capacity calculation and 3.8KN as load basic combination, get P value;3. Calculate the bending moment M = 1/4 (p * L);The flexural strength of 4 Q235, the design value of F - =215N/mm hot-rolled steel;5. Section modulus Wx of channel steel = M/f;6, check the channel section mechanical parameters, will know the specifications of channel steel.
Q:What is the maximum load-bearing capacity of channel 12M span 100?
When flat, the span of one meter is concentrated, and the solution is as follows: M=W[,]=15610*215=3356150N-mm=3.356kN-mM=L/4*N+q*L*L/8N= (M-0.1*1*1/8), *4= (3.356-0.1*1*1/8), *4=13.374kN (1.3 tons)When standing, the span of one meter is concentrated, and the solution is as follows: M=W[,]=39660*215=8526900N-mm=8.527kN-mM=L/4*N+q*L*L/8N= (M-0.1*1*1/8), *4= (8.527-0.1*1*1/8), *4=34.058kN (3.4 tons)
Q:Do galvanized steel channels need anti rust treatment?
Just like roadside poles, most of them are hot-dip galvanized, and they also have to be passivated. Of course, if you apply the paint again, the rust proof effect will be better.
Q:What does "channel weight" mean?
The channel is simply an ideal state of the weight is from the drawing to calculate the weight of steel, but after hot rolling, the size of the actual size and always on the drawings of the deviation, and generally less than the actual weight of theoretical weight.
Q:In the steel structure of steel purlin 160*60*20*2.5 what mean?
Stands for 160mm height, 60mm width, and 2.5mm thickness, and 20mm is the size of two small ears.
Q:How is the hollow tempered glass mounted on the channel steel?
Hollow two pieces of glass, there are 4 faces, from outdoor to indoor is defined as 1-4, Low-E glass film surface can only be in the cavity, that is, can only be second or third.Colorless, highly permeable Low-E is placed on third sides (Low-E glass indoors), colored on second sides (Low-E glass outside).In order to prevent the broken glass debris, doubling down side must. Because qualified laminated glass is not damaged when the debris generated, is still able to maintain its integrity.
Q:28# how to butt joint channel?
If the gap between the two weldment is not conducive to welding, it can be welded with a piece of steel plate. If the assembly gap is reasonable, direct rust removal and welding can be done.
Q:Reasons for opening holes on channel steel?
In order to make concrete filling into here to go inside, so that there would be no empty embedded sound supervision acceptance will not say do not realize as the filling.
