Abstract

The utility model provides a cold bending opening section with cross reinforcing bars. The utility model is characterized in that the shape of cross section of the section is a groove shape or a special groove shape. At least one cross reinforcing bar is arranged on the section, and the opening width B1 of the point of cross section which has no cross reinforcing bars on the section is less than or equal to the maximum width B2 of the inner cavity of the section. The utility model has the advantages of high intensity, large rigidity, large absorbing load, low cost, and light weight.

Description

Cold bending opening section with cross reinforcing bars

The utility model relates to a kind of section bar, particularly be a kind of opening cold-forming shapes with horizontal reinforcement.

Existing commercially available cold-forming shapes, when bearing transverse load, yielding on its lateral attitude.In order to improve its rigidity and intensity, people often adopt to increase the cross section and increase section bar thickness and realize that this has just increased section bar weight, has increased cost.

In view of above reason, the purpose of this utility model is for a kind of rigidity height, intensity is big, in light weight, cost the is low opening cold-forming shapes with horizontal reinforcement are provided.

Profile body is arranged in the utility model, the shape of cross section that it is characterized in that profile body is flute profile or special-shaped flute profile, on profile body, has a horizontal reinforcement at least, the cross-sectional openings width B 1 at no horizontal reinforcement place is less than or equal to the inner chamber Breadth Maximum B2(of profile body referring to Fig. 1, Fig. 3, Fig. 9 on profile body), therefore the intensity of section bar is big, rigidity big, can reduce profile body cross section and material thickness, so can alleviate section bar weight and reduce cost, the size of how much looking stressed of reinforcement quantity determines, reinforcement can be several or tens of.

Above-mentioned profile body has on the cross section at horizontal reinforcement place along horizontal reinforcement length trend, and laterally reinforcement is that the continuous reinforcement that formed by at least one straightway and/or at least one curved section is (referring to Fig. 2, Fig. 4～Fig. 8).

The continuous length of above-mentioned horizontal reinforcement is that the 1/3(of profile body cross-sectional perimeter length is referring to Fig. 7 at least).

The continuous length of above-mentioned horizontal reinforcement be profile body cross-sectional perimeter length 1/2 or grow (referring to Fig. 2) slightly.

The continuous length of above-mentioned horizontal reinforcement be profile body cross-sectional perimeter length 3/4 or grow (referring to Fig. 4, Fig. 5) slightly.

The continuous length of above-mentioned horizontal reinforcement and profile body cross-sectional perimeter equal in length or grow (referring to Fig. 8) slightly.

The lateral attitude that above-mentioned horizontal reinforcement is positioned at profile body is recessed on or protrudes from profile body (referring to Fig. 1, Fig. 2, Fig. 4), reinforcement is arranged at profile body, and to be subjected to the link of the weakness of cross force be on the lateral attitude, can improve the strength and stiffness that prevent the section bar distortion targetedly.

The utility model intensity height, rigidity is big, bearing load is big, cost is low, in light weight.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Referring to Fig. 6, laterally reinforcement 5 is made up of in the curved section 6,7 of profile body the evagination of two sections disconnections.

Referring to Fig. 7, laterally reinforcement 8 is made up of in the straightway 9,10 of profile body the evagination of two sections disconnections, and its length is about 1/3 of profile body peripheral length.

Referring to Fig. 8, laterally the length l 5 of reinforcement 11 slightly is longer than profile body profile body cross-sectional perimeter length l 6.

Referring to Fig. 9, the slot cross-section slit opening width B 3 at the no horizontal reinforcement place at profile body place approximates inner chamber Breadth Maximum B4.
