Abstract

The utility model provides a cold bent section, which is characterized in that at least one transverse reinforcing rib is arranged on a section body. The transverse reinforcing rib can be integrated with the section body into integration. The transverse reinforcing rib is positioned on a transverse position of the section body, which protrudes out of the section body or is concave towards the section body. The utility model has the advantages of high intensity, high stiffness, large absorbing load, low cost and light weight.

Description

The cold-forming shapes that horizontal reinforcement is arranged

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

Existing commercially available cold-forming shapes, yielding on its lateral attitude when bearing transverse load.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 cold-forming shapes that horizontal reinforcement is arranged are provided.

Profile body is arranged in the utility model, it is characterized in that having at least on the type body a horizontal reinforcement (referring to Fig. 1, Fig. 2), therefore the intensity of section bar is big, rigidity is big, can reduce section bar cross section and material thickness, so can alleviate section bar weight and reduce cost, reinforcement can be several or tens of, and the size of how much looking stressed of reinforcement is determined.

Above-mentioned horizontal reinforcement and section bar are an integral body (referring to Fig. 2), economical with materials, reduce cost.

Above-mentioned horizontal reinforcement is positioned on the lateral attitude of profile body, be recessed into or protrusion profile body (referring to Fig. 1, 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.

Can be according to processing technology, the user to requirement of section material appearance etc. with horizontal reinforcement along the longitudinal profile shape of section bar make special-shaped circular arc or curve or by straight line or the shape that combines by special-shaped circular arc and curve and straight line (referring to Fig. 6-Fig. 9).

The cross section shape of above-mentioned section bar is special-shaped flute profile, and the slit opening width B 1 on the horizontal section does not have the minimum widith B2 (referring to Fig. 2, Fig. 5) at horizontal reinforcement place less than the flute profile inner chamber, and purposes is wide, good looking appearance.

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

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

Fig. 1 is the utility model (having the structural representation that protrudes horizontal reinforcement).

Fig. 2 is A-A cutaway view of Fig. 1.

Fig. 3 is B-B cutaway view of Fig. 1.

Fig. 4 is the utility model (structural representation with recessed horizontal reinforcement).

Fig. 5 is C-C cutaway view of Fig. 4.

Fig. 6 is the shape figure that horizontal reinforcement is made up of special-shaped circular arc along the profile body longitudinal direction.

Fig. 7 is the shape figure that horizontal reinforcement is made up of curve along the profile body longitudinal direction.

Fig. 8 is the shape schematic diagram that horizontal reinforcement is made up of straightway along the profile body longitudinal direction.

Fig. 9 is the shape schematic diagram that horizontal reinforcement vertically is made up of special-shaped circular arc and curve along profile body.

The structure chart that Figure 10 (intermittently has and protrudes horizontal reinforcement) on profile body for horizontal reinforcement.

Figure 11 (has the structure chart that protrudes horizontal reinforcement for horizontal reinforcement continuously on profile body.

Figure 12 is horizontal reinforcement (intermittently is recessed into horizontal reinforcement) on profile body a structure chart.

Figure 13 (has recessed horizontal reinforcement) for horizontal reinforcement continuously on profile body structure chart.

The explanation of each sequence number among the above figure:

1, profile body 2, protrusion reinforcement

3, recessed reinforcement

Several and the horizontal reinforcement 2 of section bar 1 all-in-one-piece are arranged on profile body, protrude from profile body 1 referring to Fig. 1, Fig. 2.

Referring to Fig. 4, Fig. 5, several horizontal reinforcements 3 are arranged on profile body 1, be recessed in profile body 1.

Horizontal reinforcement

2,3 along the shape (referring to Fig. 6) that special-shaped circular arc forms of can serving as reasons of the shape on the profile body longitudinal direction, also can be shape of forming by curve (referring to Fig. 7) or the shape of forming by straightway (referring to Fig. 8), shape (referring to Fig. 9) or other shape of also can serve as reasons special-shaped circular arc and rectilinear(-al).

Referring to Fig. 2, Fig. 5, the transverse cross-sectional shape of section bar is special-shaped flute profile, and the slit opening width B 1 on the horizontal section does not have the minimum widith B2 of horizontal bar place less than the flute profile inner chamber.

Laterally the cross section shape of reinforcement can be continuous also can be and interrupted also can be Figure 10, Figure 11, Figure 12, shape shown in Figure 13 as Fig. 2 shape shown in Figure 5, or other shapes.
