A kind of anti-distortional buckling control with crimping channel section structure
Technical field
The utility model relates to a kind of crimping flute profile control, especially relates to a kind of anti-distortional buckling control with crimping channel section structure.
Background technology
Clod wash ultra-thin-wall shaped steel crimping channel section is widely used in low layer keel building and keel type combined wall, and distortional buckling is one of principal mode of its unstable failure, has a strong impact on its bearing capacity level.At present, clod wash ultra-thin-wall shaped steel crimping channel section member is prevented that the measure of distortional buckling from being that flat tie rod is set mostly.Flat tie rod is set to have certain effect to preventing distortional buckling, but this tie rod can only tension, can not pressurized, can only prevent in the distortional buckling pattern two edges of a wing outside a kind of failure mode of distortion simultaneously, can not prevent that two edges of a wing are simultaneously to enterolithic destruction.Novel anti-distortional buckling control adopts the steel plate tie rod of band stiffening rib, can tension also can pressurized, can prevent two kinds of mode of failure of distortional buckling simultaneously.
The utility model content
The purpose of this utility model provide for the defective that overcomes above-mentioned prior art and exist a kind of can tension also can pressurized, can prevent the anti-distortional buckling control with crimping channel section structure of two kinds of mode of failure of distortional buckling simultaneously.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of anti-distortional buckling control with crimping channel section structure, this control is connected on the crimping of crimping channel section for the steel plate of band stiffening rib, the screw by two ends.
Described control middle part is parallel to be provided with two stiffening ribs that are isosceles-trapezium-shaped.
Described stiffening rib and steel plate are vertical setting.
Described control is embedded the opening part at c-shaped crimping channel section.
Compared with prior art, the utility model adopts the tie rod of band stiffening rib, can tension also can pressurized, can prevent two kinds of mode of failure of distortional buckling simultaneously, and then improve the bearing capacity of crimping channel section.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of anti-distortional buckling control 1, its structure with crimping channel section structure as shown in Figure 1, this control 1 is made up of stiffening rib 11 and steel plate 12, the screw 2 by two ends is connected on the crimping of crimping channel section 3.Wherein, stiffening rib 11 is an isosceles-trapezium-shaped, is provided with two altogether, is set in parallel in the middle part of control 1, and vertical with steel plate 12.The utility model adopts the steel plate 12 of band stiffening rib 11, can tension also can pressurized, can prevent two kinds of mode of failure of distortional buckling simultaneously.Anti-distortional buckling control 1 with crimping channel section structure is connected on the crimping of crimping channel section 3 by the screw 2 at two ends, can effectively prevent distortional buckling.
