[0024] Reference will now be made in detail to the embodiments of the present disclosure, one or more examples of which are set forth herein below. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and is not intended to be limiting. On the contrary, the following description provides a convenient illustration of exemplary embodiments for implementing the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made within the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0025] like Figures 1-4 As shown, the utility model discloses a column docking connector, wherein the column 1 is an axisymmetric columnar structure with one side open. After docking, since the columns at the docking position lack a reinforced structure after assembly, the open side of the column 1 will tend to shrink inward or the column 1 will tend to bend along the axial direction due to the force.

[0026] The connecting piece of the present invention includes a connecting body 2, which has a fixing surface 3 that fits with the surface of the column. The fixing surface 3 and the column 1 are locked and fixed by a bolt 4 that passes through to complete the docking of the column end. At the same time, in order to reduce the deformation of the column, the present invention is provided on the connecting body 2 with a first support portion 5 for supporting the open side of the column when the column 1 is deformed by force and a second support portion 6 for providing support when the column 5 is bent and deformed at the docking point.

[0027] Specifically, if Figure 4 As shown, the number of connecting members of the present invention is two groups, which are symmetrically arranged about the center of the open side of the column 1. The first support portion 5 of each connecting member fits against the inner surface of the open side of the column 1, and the second support portion 6 is located on the adjacent side of the two connecting members. When the column is bent and deformed, the second support portions 6 of the two connecting members approach and abut each other, providing support force for the column 1 at the joint.

[0028] The first support portion 5 and the second support portion 6 of the utility model are both bent surfaces extending from the connecting body 2. The bending angle of the first support portion 5 relative to the connecting body 2 is adapted to the angle of the inner surface profile of the column 1. The second support portion 6 is bent to the side away from the inner surface of the column 1 at the corresponding position. A triangular structure is formed between the surfaces of the two second support portions 6 and the corresponding inner surfaces of the column 1. In the initial docking state, there may be a certain gap between the first support portion 5 and the inner surface of the column. At the same time, a certain assembly gap is also left between the ends of the second support portion 6, so that the connector can be smoothly installed in the column. When the column is deformed to a range beyond the original gap, the connector of the utility model can provide supporting force for the column to enhance the structural strength of the column docking point at this time and improve the safety of the structure.

[0029] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, during assembly, the open side of the column 1 still needs to be assembled with other components. Therefore, the length of the bending surface of the first support portion 5 cannot exceed the inner wall of the open side of the column and cannot be too long, otherwise it will block the opening of the column 1 and affect the subsequent installation. The second support portion 6 needs to provide support when the column is bent. Therefore, the supporting effect of the second support portion 6 must be guaranteed. During sheet metal processing, the larger the bending angle, the lower the strength of the bending part, and the shorter the bending surface length, the higher the strength of the bending surface. Therefore, it is necessary to control the angle between the second support portion 6 and the connecting body 2 and the bending surface length of the second support portion 6; the wider the bending surface, the lower the bending strength. The larger the force arm generated at the bending part when the end is subjected to force, the greater the angle needs to be increased as much as possible. Therefore, it is necessary to comprehensively consider the relationship between the bending width and the angle size based on the possible force balance of the second support part 6; in an embodiment of the present invention, based on the type of connected columns, the bending surface length of the first support part 5 of the present invention is smaller than the bending surface length of the second support part 6, and the bending angle of the second support part 6 relative to the connecting body 2 is greater than the bending angle of the first support part 5 relative to the connecting body 2; the angle of the second support part 6 relative to the connecting body 2 is 135°; the angle of the first support part 5 relative to the connecting body 2 is 115°.

[0030] The fixing surface of the connecting body 2 is provided with a bolt hole 7 for matching with the bolt. When the column is actually connected, a single fixing surface can be set to be fixed with the column 1 using bolts according to the needs, or multiple fixing surfaces can be set to improve the fixing effect, such as Figure 3 As shown, in an embodiment of the present invention, the connecting piece has two fixing surfaces that cooperate with the inner surface of the column 1. When there are multiple fixing surfaces, because bolts are used for fixing, in order to avoid interference between the bolts of different fixing surfaces, the bolt holes on the adjacent surfaces of the connecting body 2 of the utility model are arranged in a staggered manner.

[0031] The present invention also discloses a vertical warehouse, comprising a plurality of columns 1 for building the warehouse, wherein the butt ends of adjacent columns 1 are butt-connected via the above-mentioned column butt connectors. When the column butt connectors of the present invention are used to build the vertical warehouse, the connectors are first bent according to the contour lines of the inner surfaces of the columns 1 to be connected to form a fixing surface and a corresponding supporting portion, and then the connectors are inserted from the ends of the columns 1, and the connectors and the ends of the two butt-jointed columns 1 are maintained to have an overlapping area of ​​approximately equal length to ensure that the bolts are evenly stressed, and finally the bolts are inserted to be locked and fixed to complete the butt connection of the column ends.
