[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0030] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The present invention provides a multi-directional connection column. Figure 1-Figure 5 As shown, the multi-directional connection column includes:

[0032] The base 130 and the concrete column 300 are provided with an extension column 110 at one end of the base 130 away from the concrete column 300. The end surface of the base 130 connected to the extension column 110 is also provided with an annular groove 120. The base 130 is integrally formed with the top of the concrete column 300 during the casting of the concrete column 300 to form an integral structure.

[0033] The connecting pipe 200 includes a ring body 210, a limiting insert ring 230, and an external connecting plate 220 provided on the circumference of the ring body 210. The limiting insert ring 230 is inserted into the annular groove 120 from the end of the extension column 110 away from the concrete column 300. After the limiting insert ring 230 is inserted into the annular groove 120, the ring body 210 is wrapped around the outside of the extension column 110. The connecting pipe 200 is nested on the circumference of the extension column 110 through the ring body 210 and the limiting insert ring 230. The external connecting plate 220 serves as a connection end point for the corresponding support structure, helping the support structure to achieve higher connectivity.

[0034] In this embodiment, the connecting pipe 200 is fastened to the base 130 and the extension column 110 by bolts after being nested. The connecting pipe 200 is designed to be separate from the base 130 and the extension column 110 mainly to take into account the needs during transportation. This prevents the connecting pipe 200 with the external plate 220 from being damaged during transportation, and allows for secondary assembly on site.

[0035] The connecting pipe 200 and the concrete column 300 that supports the column are connected by the ring body 210 and the limiting insert ring 230, and the base 130 and the extension column 110, thereby improving the connectivity of the column structure. At the same time, the additional external connecting plate 220 is used to provide fixed end surfaces for more connecting structures.

[0036] As a preferred implementation in this embodiment, a first limiting groove 111 is provided on the side wall of the extension column 110; a limiting ring is provided on one end of the base 130 close to the extension column 110, and the limiting ring is nested around the circumference of the extension column 110 and a certain gap is formed between the limiting ring and the extension column 110, and the gap between the limiting ring and the extension column 110 forms an annular groove 120; a second limiting groove 121 is provided on the side wall of the limiting ring close to the extension column 110;

[0037] When the limiting insert ring 230 is inserted into the annular groove 120, the limiting insert block 231 provided on the outer wall of the limiting insert ring 230 is adapted to the second limiting groove 121 and gradually enters the second limiting groove 121 during the insertion process of the limiting insert ring 230; the inner wall of the ring body 210 is provided with a main limiting block 240, which extends from the inner wall of the ring body 210 to the inner wall of the limiting insert ring 230. During the insertion process and after the insertion is completed, the main limiting block 240 limits the deflection between the connecting pipe 200 and the extension column 110, thereby enhancing the structural stability;

[0038] As a preferred embodiment of this embodiment, the ring body 210 is provided with a fixing screw hole 211, and the fixing screw hole 211 passes through the main limit block 240 provided on the inner wall of the ring body 210; the first limit groove 111 is provided with a mounting screw hole adapted to the fixing screw hole 211, and after assembly is completed, the ring body 210 and the extension column 110 are fixedly connected by fastening with a stud, thereby improving the structural connection strength;

[0039] As a preferred implementation of this embodiment, the number of the limiting inserts 231 is no less than four groups. The limiting inserts 231 have a right-angled triangular cross-section. To improve smoothness and reduce resistance during insertion, the right angles of the limiting inserts 231 are directed away from the base 130, and an inclined surface structure is used to facilitate docking during assembly.

[0040] The second limiting groove 121 has the same structure as the limiting insert 231;

[0041] As a preferred implementation of this embodiment, the number of the external plates 220 is four or eight groups distributed in a circular array on the outer wall of the ring body 210, and the limiting plugs 231 and the external plates 220 are staggered to avoid excessive stress concentration inside and outside the area where the limiting plugs 231 and the external plates 220 are located, which may cause damage to the ring body 210;

[0042] The external connecting plate 220 is provided with screw holes for connecting to other structures, so as to provide support functions for other supporting structures;

[0043] The principle of this utility model is as follows:

[0044] During the processing and forming stage of the concrete column 300, the base 130 and the concrete column 300 are integrally formed. After the processing is completed, the concrete column 300 with the base 130 and the connecting pipe 200 are respectively delivered to the assembly site. After arriving at the assembly site, the concrete column 300 is first buried, and then the connecting pipe 200 is nested on the top of the base 130. During the nesting process, the position of the main limit block 240 in the ring body 210 is first aligned with the position of the first limit groove 111 on the extension column 110, and then the connecting pipe 200 is pushed toward the base 130. During the pushing process, the limit insert ring 230 will be inserted into the ring groove 120, and the limit insert block 231 will gradually enter the second limit groove 121. The limit insert block 231 and the main limit block 240 provide limiting capabilities from the inside and outside to resist torsional forces, thereby avoiding damage to the equipment caused by internal and external torsional forces, improving the stability of the structure and being able to cope with more severe environments.
