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.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present, secured by intervening elements. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 3 show a column of the present invention, which includes a main body 10, a reinforcing rib 20, a reinforcing edge 30, and a reinforcing rib 40.

The main body 10 is a hollow structure, and a hollow cavity is formed inside the main body 10. The main body 10 includes a plurality of sidewalls 11, and the plurality of sidewalls 11 enclose a hollow cavity. Corners are formed between the adjacent sidewalls 11. In the present embodiment, the number of the side walls 11 is four, and the four side walls 11 form a rectangular structure. Four corners are formed between the four side walls 11. The side wall 11 is made of gray cast iron, and the wall thickness of the side wall 11 is 20-30 mm. The

sidewalls

11 and 11 are rounded to eliminate stress concentration.

The reinforcing ribs 20 are located within the hollow cavity for reinforcing the overall structural strength of the column. The reinforcing rib 20 comprises a plurality of reinforcing plates 21, and the plurality of reinforcing plates 21 are arranged in a crossed manner. Each reinforcing plate 21 extends from both sides thereof at corners of the main body 10. The intersection of several stiffening plates 21 is located at the centroid of the hollow cavity. Specifically, the number of the reinforcing plates 21 is two, and the two reinforcing plates 21 are crossed to form an X-shaped structure. The die angles on both sides of the reinforcing plate 21 reduce the friction force during the ejection of the die. Each reinforcing plate 21 is provided with lightening holes 210, and the lightening holes 210 are used for reducing the weight of the reinforcing plate 21. The number of the lightening holes 210 on each reinforcing plate 21 is multiple, and the plurality of lightening holes 210 are uniformly arranged. The reinforcing beads 20 extend entirely through the main body 10 from the bottom end to the top end of the main body 10.

The reinforcing rim 30 is provided on the inner wall of the side wall 11. The reinforcing edges 30 are mutually perpendicular extending edges forming a grid structure.
