Abstract
The utility model relates to an improvement of the profile of the angle steel. The aim of the improvement is metal saving. The profile of the angle steel is in a stepped shape. The end part of the inner side of the angle steel legs are higher than the bottom. The bottom is in a rectilinear shape. The inner side of the angle steel legs are in a stepped shape. The inner side of the intersection position of the bottoms of the two angle steel legs are in an arc shape. The angle steel can save metal 5-15% under the premise of keeping the primary performance.
Description
The present invention is the improvement to the angle steel section.
Angle steel is a large amount of shaped steel that use, and Fig. 1 is common sectional schematic diagram, this section waste metal.The Soviet Union " Cra π b " 1984 9 phases of magazine disclose a kind of economic section angle steel, and Fig. 2 is its sectional schematic diagram, have saved part metals in basic the maintenance under original performance prerequisite.But can not save metal morely.
The present invention seeks to improve the angle steel section, rationally utilize material, save metal.
Technical scheme is: keep under the angle steel performance prerequisite basic, the end that section configuration is changed into the angle steel inboard leg is higher than the bottom, and the bottom is a linear, and the angle steel leg is stepped.Inboard, angle steel two leg intersection is the garden arcuation.
For guaranteeing the STEPPED-SECTION ANGLE STEEL performance, the end of angle steel leg can be thickeied slightly, the thickness of increase is between 0～20mm.
The present invention is applicable to various hot-rolled angle steels and since section on ladder length and suitable range of choice is highly arranged, can save more metal.Compare with section angle steel commonly used, generally save metal 5～15%.
Embodiment 1
Fig. 3 is embodiment 1 sectional schematic diagram, and each size is as follows: (mm of unit)
b＝100 d＝10 e＝5.5 f＝2 r＝10
Embodiment 2
D among the embodiment 1 is increased 0.5mm, and r becomes 18mm, all the other size constancies.
Embodiment 3
Fig. 4 is embodiment 3 sectional schematic diagrams, and each size is as follows: (mm of unit)
b＝100 d＝10 e＝8 f＝2.5 r＝13
Embodiment 4
D among the embodiment 3 is increased 2mm, all the other size constancies.
Subordinate list is the embodiment of the invention and common angle steel performance comparison sheet, and symbolic significance is as follows in the table:
I: the moment of inertia (cm
4) Z
0: centroidal distance (cm)
I: the radius of inertia (cm) N: metal saving rate
F: area (cm
2) W: section factor (cm
3)
As can be seen from the table: compare with common angle steel, embodiment 1 and 3 performance slightly descend, but metal saving rate is respectively 10.04% and 14.46%; Embodiment 2 and 4 performance slightly rise, and metal saving rate is respectively 5% and 8.4%.
W/F value in the table is big more, illustrates that the angle steel section gets over economical rationality, of the present invention should value all greater than common angle steel.
Claims (2)
1, a kind of STEPPED-SECTION ANGLE STEEL is characterized in that section configuration is:
(1) end of angle steel inboard leg is higher than the bottom, and said bottom is a linear, angle steel leg inboard stepped;
(2) inboard, intersection, angle steel two legs bottom is the garden arcuation.
2, the angle steel according to claim 1 is characterized in that the end of angle steel is thickeied slightly, and the thickness of increase is H, 0＜H≤20mm.
