In steel structures, what is the meaning of the "" between the two members of the H steel brace 2L 180*12,10?
Angle called angle, the steel strip is perpendicular to each other on both sides into angular. Equilateral angle steel and unequal angle points. An equal angle two edge width is equal. The specification is expressed by edge width * width * mm thick edge edge. Such as "/ 30 x 30 x 3", that is an equal angle the width is 30 mm, 3 mm thick. Also available models that model is the edge width cm, such as angle 3#. models do not represent the same type in different edge thickness dimensions, and thus in the contract and other documents will be the angle edge width, edge thick size fill in complete, avoid separately represented by models hot rolled edge angle specifications for 2#-20#.
Specific means: double angle, angle type: L180*180*12, because the angle is equal angles, so it can be omitted in: L180*12. where: 180 refers to the angle of the width, 12 refers to the average thickness of.L boundary angle is the angle of the code before the.L 2 is Larry.
Mainly divided into equilateral angle steel and equilateral angle steel two categories, the unequal angle can be divided into equilateral equilateral thick and unequal thickness two. Angle expressed side and edge thickness size. The current domestic steel specifications for 2 - 20 cm, to length number is the same number. Horn steel often have 2 - 7 different edge thickness. The actual size and the import side angle marked on both sides of the thickness and indicate the relevant standards. The general side of 12.5cm over the large angle, 12.5cm - 5cm for the medium angle, length below 5cm for small angle. The order of a steel export angle to use specification for steel, the carbon steel grades. The corresponding angle in addition to standard number, no specific composition and performance series. Puri steelThe fixed angle delivery length ruler, size two, domestic angle length range is 3 - 9m, 4 - 12M, 4 - 19m, 6 - four 19m range according to the different specifications. The Japanese steel section length range is 6 - 15m. unequal angle height according to length the edge of the equilateral angle steel wide to calculate.
