Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

Example 1

As shown in fig. 1-2, an open-type profile is characterized in that: comprises a top surface 1, a side surface 2 and a bottom surface 3; the bottom surface 3 is provided with an opening 4, the top surface 1 is at least provided with two arc grooves 11 which are recessed inwards along the length direction of the section bar, the two arc grooves 11 are connected through a first connecting section 12, and the width of the first connecting section 12 is smaller than that of the opening 4; the side surfaces 2 are arranged perpendicular to the top surface 1, and the bottom surface 3 is provided with a bending part 31 which is concave inwards. The utility model discloses a section bar integrated into one piece adopts open type structure, and the steel band is through the roll-in one shot forming of multichannel, and side 2 sets up perpendicular setting with top surface 1 perpendicularly and can let the section bar bear bigger power, and in addition, the bottom of section bar is provided with symmetrical 2 bottom surfaces 3, and two bottom surfaces 3 are the symmetrical setting, and the symmetrical setting can let the section bar atress more even, also can make the intensity of section bar more big, in addition the utility model discloses an open type design; therefore, the design can realize the light weight of the section bar and also can effectively improve the self-generated rigidity and strength of the section bar.

The top surface 1 comprises a second connecting section 13 which can be connected with the side surface 2, and the width of the second connecting section 13 is smaller than that of the first connecting section 12; the distance between the arc top ends of the two arc grooves 11 is smaller than the width of the opening 4. The utility model discloses a top surface is provided with arc recess 11, can regard as arc recess 11 to be the strengthening rib structure, and this structure can improve 12% compressive strength and torsional strength of section bar. In addition, the section bar of the utility model adopts ultra-high strength material, the material hardness HRC is more than or equal to 45 degrees, and the tensile strength reaches 1500-2400 Mpa. The purposes of high strength and light weight of the sectional material are achieved through the combined action of the structure and the material of the sectional material.

The second connecting portion 13 is connected to the side face 2 by a first chamfer 51, and the side face 2 is connected to the base face 3 by a second chamfer 52. The first chamfer 51 and the second chamfer 52 enable the profile to be smoother, less prone to scratching during transport, and the design of the radian is firmer than that of the right-angle shape.
