Q:248 H steel GB thickness?
The section is 248mm high, the section width is 124mm, the web thickness is 5mm, and the flange thickness is 8mm.
Q:In the H steel frame, what is the connection between the secondary beams? Welding or high strength bolt connection?
Two can, anyway, there are connections, the strength can be guaranteed, it depends on the construction requirements and subsequent demolition requirements.
Q:What does "welding H" steel set "vertical" and "corrective processing" mean?
Since the H steel web needs to be machined is 10 thick, it can be easily welded to the submerged welding machine, so there is no need to break the seamAfter blanking, use the crane to lift the plate to the erection machine one by one, and clamp. Start the set, set the machine, adjust the position of the three plates, and fix the spot weldingNote: the assembling machine is specially used to assemble the H steel machine, three plates, processing it can clamp type H steel H steel will start the machine, by the end of the assembling machine to roll to the other end, through assembling the machine when the door frame, can be used to adjust the assembling machine accurate three plate position, is a period of adjustment of rolling.After erection, the crane is welded to the welding platform and submerged arc weldingAfter welding, lift to straightening machine for straightening and correctingNote: the straightening effect correction principle: after welding flange may be not perpendicular to the web, using roller flat. Because H type steel may also be in the length direction is not straight, also can use the pressure roller is adjusted. The general steel processing plant of the straightening machine only in H flat slab steel width flat with length up straight. Straight up the length function of flame correction, flame correction, H steel with roasted curved, roasted red with water, due to thermal expansion and contraction, H type steel straight up. But it must have some experience to master the operation.
Q:What's the difference between I-beam and H steel?
H steel is a kind of economical section steel with better mechanical properties than I-beam. Its shape is named after its English letter "H". The flange of hot rolled H steel is wider than that of I-beam, big lateral rigidity and strong bending resistance. Under the same specifications, H steel is lighter than i-beam.
Q:H steel or I-beam, which bearing good?
If load-bearing, H steel is better.
Q:Which is better, I-beam or HN steel?
Mainly to see what you mean, I-beam and HN steel beams of what size, or look at section size. Generally I-beam is stronger
Q:What are the materials of H steel?
It consists of Q+ digital + quality grade symbol + deoxidization method symbol. The steel dubbed "Q", representing the yield point of steel, behind the digital representation of the yield point value, in units of MPa such as Q235 (s) said the yield point for carbon steel 235 MPa.
Q:Specification for splicing length specification of H steel in steel structures
Flange welding H steel joint seam spacing spell and the web, not less than 200mm. of flange splicing length should not be less than 600mm
Q:How much is the weight of 200x200 H steel?
200*200*8*12 is commonly used and weighs 50.5kg/ meters
Q:What is the length of the butt joint of H steel? What is the minimum requirement?
H type steel butt joint is not required for length, but oblique, generally 45 degrees, that is to say, not less than the length of at least H steel height.
