Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Please refer to fig. 1-4, which illustrate an open cold-formed steel with a stable structure, comprising a steel body 1, wherein a through hole is formed in the steel body 1, the steel body 1 is rectangular, an opening 2 is formed at the lower part of the steel body 1, a connecting block 3 is arranged in the opening 2, an embedding groove 4 is formed on the upper wall inside the steel body 1, a group of bearing bars 5 is arranged in the steel body 1, a supporting block 6 is arranged at the lower end of each bearing bar 5, the supporting block 6 is triangular, a cavity is formed inside the steel body 1, and a supporting member 8 is arranged in the cavity.

Further, the bearing strip 5 is arranged by taking the central part of the embedding groove 4 as a mirror image, and the bearing strip 5 is arranged in an inclined manner, so that the bearing strip 5 is stably connected with the embedding groove 4 and the steel part body 1, the whole structure of the steel part body 1 is stable, and the stability of the steel part body in the using process is ensured. The upper end of bearing strip 5 is equipped with joint portion 7, and joint portion 7 is established in inlay groove 4, support when can realizing 1 lateral wall atress of steel part body, in the atress, avoids bearing strip 5 to shift. The lower extreme of bearing strip 5 is connected with the hypotenuse of supporting shoe 6 for the lower extreme atress of bearing strip 5 is even, when preventing that steel part body 1 from receiving great bearing capacity, takes place the phenomenon of bending easily. Support piece 8 is aluminum alloy, and support piece 8 is triangle-shaped, and closely arranges between support piece 8 for support piece 8 can not rust easily in moist environment, and support piece forms stable triangular supports structure simultaneously, very big improvement the intensity of cold-formed steel, the phenomenon of bending takes place easily for the anti bending performance that has improved cold-formed steel.
