The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0023] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples.

[0024] The pier column according to an embodiment of the present utility model will be described below with reference to the drawings.

[0025] As Figures 1 - 4 shown, the pier column 100 according to an embodiment of the present utility model includes: a pier column main body 1, a base 2 and a limit bracket 3. A connection slot 11 is provided at the bottom surface of the pier column main body 1. The base 2 is provided at the lower end of the pier column main body 1. A connection column 21 is provided on the top surface of the base 2. The connection column 21 is inserted into the connection slot 11 and connected to the pier column main body 1. That is to say, the pier column main body 1 is positioned with the base 2 through the insertion fit of the connection slot 11 and the connection column 21, and the pier column main body 1 is connected to the base 2 through the connection with the connection column 21. It can be understood that the insertion fit method is simple, easy to operate, and is conducive to improving the connection efficiency between the base 2 and the pier column main body 1.

[0026] Among them, the limiting brackets 3 are arranged on the base 2 in a switchable manner between a first position and a second position, and there are multiple limiting brackets 3. The multiple limiting brackets 3 are arranged on the outer peripheral side of the pier column body 1 along the circumferential direction of the pier column body 1. In the first position, the limiting brackets 3 are spaced apart from the pier column body 1. When the limiting brackets 3 move from the first position towards the second position, they are adapted to contact the outer peripheral surface of the pier column body 1 and push the pier column body 1 until the connecting slot 11 and the connecting column 21 are arranged opposite to each other in the up and down direction.

[0027] That is to say, the limiting brackets 3 can be switched between a first position spaced apart from the pier column body 1 and a second position contacting the outer peripheral surface of the pier column body 1. By switching the limiting brackets 3 to the first position spaced apart from the pier column body 1, interference of the limiting brackets 3 with the installation of the pier column body 1 can be avoided. When the pier column body 1 moves from the first position towards the second position, it moves towards the direction close to the pier column body 1 and finally contacts the outer peripheral surface of the pier column body 1. When the limiting brackets 3 are in the second position, the connecting slot 11 and the connecting column 21 are arranged opposite to each other in the up and down direction. Thus, under the limitation of the limiting brackets 3, the pier column body 1 can be moved towards the direction close to the base 2 to achieve the insertion fit between the connecting column 21 and the connecting slot 11.

[0028] Therefore, during the process of installing the pier column body 1 onto the base 2, by controlling the limiting brackets 3 to move from the first position towards the second position, the pier column body 1 can be better pushed until the connecting slot 11 and the connecting column 21 are arranged opposite to each other in the up and down direction, so that the position offset during the installation of the pier column body 1 onto the base 2 can be better corrected. Furthermore, the quick positioning of the connecting column 21 and the connecting slot 11 can be achieved, which is beneficial to improving the connection efficiency between the pier column body 1 and the base 2. In addition, there are multiple limiting brackets 3 arranged on the outer peripheral side of the pier column body 1, so that the multiple limiting brackets 3 can limit the pier column body 1 from different positions in the circumferential direction of the pier column body 1, thereby ensuring that the multiple limiting brackets 3 can push the pier column body 1 with offsets in different directions to make the connecting slot 11 and the connecting column 21 arranged opposite to each other in the up and down direction, which is beneficial to improving the positioning accuracy of the installation position of the pier column body 1 on the base 2. And, after the connecting column 21 and the connecting slot 11 are inserted, the limiting brackets 3 can always remain in the second position, which can better ensure the position accuracy when the pier column body 1 moves towards the direction close to the base 2, so as to prevent the pier column body 1 from generating a position offset in the horizontal direction relative to the base 2 during the insertion process of the connecting column 21 and the connecting slot 11, and to improve the installation accuracy of the pier column body 1 on the base 2.

[0029] Specifically, a limiting support portion 31 is formed on the limiting support bracket 3. The limiting support portion 31 is the contact position between the limiting support bracket 3 and the outer peripheral surface of the pier column main body 1 when the limiting support bracket 3 is in the second position. For the convenience of description, the height of the limiting support portion 31 when the limiting support bracket 3 is in the second position is defined as the limiting height. During the process of installing the pier column main body 1 onto the base 2, when the bottom surface of the pier column main body 1 is lower than the limiting height, the limiting support bracket 3 can be moved from the first position to the second position. Therefore, when the pier column main body 1 generates a position offset in the horizontal direction relative to the base 2, the limiting support bracket 3 corresponding to the pier column main body 1 in the offset direction can contact the outer peripheral surface of the pier column main body 1 and push the pier column main body 1 to move towards the opposite direction of the offset direction until the connection slot 11 and the connection column 21 are arranged opposite to each other in the up-down direction.

[0030] For the pier column 100 according to an embodiment of the present invention, during the process of installing the pier column main body 1 onto the base 2, by controlling the limiting support bracket 3 to move from the first position towards the second position, the pier column main body 1 can be preferably pushed to a position where the connection slot 11 and the connection column 21 are arranged opposite to each other in the up-down direction, so that the position offset when the pier column main body 1 is installed onto the base 2 can be preferably corrected, and further, the rapid positioning of the connection column 21 and the connection slot 11 can be achieved, which is beneficial to improving the connection efficiency between the pier column main body 1 and the base 2.

[0031] In a specific embodiment, the pier column main body 1 is in a square column shape, and the pier column main body 1 has four side surfaces. Four limiting support brackets 3 corresponding to each side surface are provided on the base 2. Therefore, during the process of installing the pier column main body 1 onto the base 2, the installation direction of the pier column main body 1 can be limited from four different directions by the four limiting support brackets 3. For example, when the pier column main body 1 is offset to the left relative to the base 2, the limiting support bracket 3 located on the left side of the pier column main body 1 can be used to push the pier column main body 1 to move to the right, and the limiting support bracket 3 located on the right side can prevent the pier column main body 1 from generating a position offset to the right relative to the base 2 to ensure that the connection slot 11 and the connection column 21 are aligned in the left-right direction. Similarly, the connection slot 11 and the connection column 21 can be ensured to be aligned in the front-back direction by the two limiting support brackets 3 located on the front side and the rear side of the pier column main body 1. Thus, it can be ensured that the connection slot 11 and the connection column 21 are aligned in the up-down direction to achieve the rapid positioning of the connection column 21 and the connection slot 11.

[0032] Among them, in the width direction of the side surface of the pier column main body 1, the ratio of the size of the limit support part 31 to the size of the pier column main body 1 is 0.7 - 0.9. Among them, on the basis that the size of the pier column main body 1 remains unchanged, the larger the size of the limit support part 31, the greater the weight of the limit support part 31, the larger the contact area between the limit support part 31 and the pier column main body 1, and the higher the efficiency of the limit support 3 in pushing the pier column main body 1; conversely, the smaller the size of the limit support part 31, the smaller the weight of the limit support part 31, the smaller the contact area between the limit support part 31 and the pier column main body 1, and the lower the efficiency of the limit support 3 in pushing the pier column main body 1. Therefore, in the radial direction of the pier column main body 1, setting the ratio of the size of the limit support part 31 to the size of the pier column main body 1 within the range of 0.7 - 0.9 can avoid the excessive weight of the limit support part 31, and at the same time can avoid the too small contact area between the limit support part 31 and the pier column main body 1, and the too low efficiency of the limit support 3 in pushing the pier column main body 1, so as to reduce the weight of the limit support part 31 and improve the efficiency of the limit support 3 in pushing the pier column main body 1. Among them, in the width direction of the side surface of the pier column main body 1, the ratio of the size of the limit support part 31 to the size of the pier column main body 1 can be 0.7, 0.73, 0.75, 0.78, 0.8, 0.82, 0.85, 0.9, etc., and no specific limitation is made here.

[0033] In some embodiments, the pier column main body 1 and the connecting column 21 can be connected by bolts. The connecting column 21 is provided with threaded holes, and the outer surface of the pier column main body 1 is provided with connecting holes. The connecting holes are communicated with the connecting slots 11 and are arranged corresponding to the threaded holes. Bolts can pass through the connecting holes and be connected to the threaded holes of the connecting column 21, so that the pier column main body 1 and the connecting column 21 are connected by bolts; the pier column main body 1 and the connecting column 21 can also be connected by concrete. By filling the gap between the connecting column 21 and the connecting slot 11 with concrete, after the concrete solidifies, the connecting column 21, the concrete and the connecting slot 11 form a whole, so that the connecting column 21 and the pier column main body 1 are connected by concrete; the pier column main body 1 and the connecting column 21 can also be connected by bolts and concrete at the same time, so as to further improve the connection reliability between the connecting column 21 and the pier column main body 1.

[0034] In some embodiments, the connecting column 21 is a steel bar. During the pouring process of the base 2, a part of the connecting column 21 is inserted into the base 2. After the base 2 is poured and formed, the connecting column 21 is fixedly connected to the base 2, that is, a part of the connecting column 21 is embedded in the base 2, so as to improve the connection reliability between the connecting column 21 and the base 2.

[0035] According to some embodiments of the present utility model, at the second position, the contact position between the limit support 3 and the outer peripheral surface of the pier column main body 1 is the limit support portion 31, and the height of the limit support portion 31 is not lower than the height of the connecting column 21. That is to say, when the limit position 3 is in the second position, the upper end of the connecting column 21 is flush with the limit support portion 31, or the upper end of the connecting column 21 is located below the limit support portion 31. That is, during the process of the base 2 and the pier column main body 1 approaching each other, the limit support portion 31 can contact the outer peripheral surface of the pier column main body 1 before the connecting column 21 is inserted into the connecting slot 11, so as to ensure the stability of the limit support 3 for correcting the position deviation of the pier column main body 1 relative to the base 2.

[0036] According to some embodiments of the present utility model, the limit support 3 includes a support body 32, and the limit support portion 31 is formed as a roller rotatably provided on the support body 32. The rotation axis of the limit support portion 31 is parallel to the horizontal direction, and at the second position, the outer peripheral surface of the limit support portion 31 abuts against the outer peripheral surface of the pier column main body 1. That is to say, when the limit support 3 is in the second position and the limit support portion 31 contacts the outer peripheral surface of the pier column main body 1, when the pier column main body 1 moves towards the direction close to the base 2, it can push the limit support portion 31 formed as a roller to rotate, thereby avoiding the frictional force caused by the relative friction between the outer peripheral surface of the limit support portion 31 and the outer peripheral surface of the pier column main body 1, and further reducing the moving resistance when the pier column main body 1 moves towards the direction close to the base 2, so as to reduce the force required for installing the pier column main body 1.

[0037] In some embodiments, the limit support 3 is detachably provided on the base 2, so that the limit support 3 can be flexibly installed on the base 2 or removed from the base 2 according to the use requirements, so as to improve the flexibility of using the limit support 3.

[0038] According to some embodiments of the present utility model, the limit support portion 31 is provided at the upper end of the support body 32. That is to say, the limit support portion 31 is at a relatively high position. Thus, the height of the part of the limit support 3 for limiting the pier column main body 1 can be increased well, so as to ensure that the limit support portion 31 can contact the outer peripheral surface of the pier column main body 1 before the connecting column 21 enters the connecting slot 11, so as to improve the stability of the limit support 3 for limiting the pier column main body 1. In addition, the support body 32 above the limit support portion 31 of the limit support 3 can be omitted, simplifying the structure of the limit support 3, reducing the size of the limit support 3 in the axial direction of the pier column main body 1, and thus reducing the cost of the limit support 3.

[0039] According to some embodiments of the present utility model, the lower end of the limiting bracket 3 is rotatably provided on the base 2. That is to say, the limiting bracket 3 can be switched between the first position and the second position by rotation. Thus, the connection structure between the limiting bracket 3 and the base 2 can be preferably simplified, and the difficulty of switching the limiting bracket 3 between the first position and the second position can be reduced. For example, only a thrust force towards the direction close to the pier body 1 needs to be applied to the limiting bracket 3. At the same time, the moving friction of the limiting bracket 3 is small, which can reduce the friction loss of the limiting bracket 3, thereby improving the reliability of the limiting bracket 3.

[0040] In some other embodiments, the lower end of the limiting bracket 3 is slidably provided on the base 2. That is to say, the limiting bracket 3 can be switched between the first position and the second position by sliding. Therefore, the limiting bracket 3 only needs to overcome the friction force when moving, and the thrust force required for the sliding movement of the limiting bracket 3 is small, thereby reducing the energy consumption of the movement of the limiting bracket 3.

[0041] According to some embodiments of the present utility model, a handle 33 is provided on the limiting bracket 3. That is to say, a thrust force can be applied to the limiting bracket 3 through the handle 33 to drive the limiting bracket 3 to move between the first position and the second position, which is beneficial to reducing the operation difficulty of the limiting bracket 3.

[0042] In some embodiments, the handle 33 is provided adjacent to the top end of the limiting bracket 3, and the lower end of the limiting bracket 3 is rotatably provided on the base 2 or the lower end of the limiting bracket 3 is slidably provided on the base 2. Thus, the distance between the handle 33 and the lower end of the limiting bracket 3 can be preferably increased, thereby increasing the lever arm of the thrust force applied by the handle 33 to the limiting bracket 3, and further reducing the thrust force required to push the limiting bracket 3, which is convenient for moving the limiting bracket 3.

[0043] According to some embodiments of the present utility model, connecting portions 34 are provided at both ends of the limiting bracket 3 in the circumferential direction of the pier body 1, and the limiting bracket 3 is adapted to be connected to the connecting portions 34 of the adjacent limiting brackets 3 through the connecting portions 34. That is to say, after the limiting bracket 3 moves to the second position and the pier body 1 is positioned, all the limiting brackets 3 can be connected to the connecting portions 34 of the adjacent limiting brackets 3 through the connecting portions 34 at both ends, so that all the limiting brackets 3 are fixedly connected into a whole, thereby keeping the limiting bracket 3 in the second position, ensuring that the limiting bracket 3 can maintain the limiting effect on the pier body during the installation process, and further enabling the pier body 1 to generate a horizontal offset relative to the base 2 when moving in the direction close to the base 2, which is beneficial to improving the stability when the pier body 1 is installed on the base 2. At the same time, after the pier body 1 is connected to the base 2, the pier body 1 can be prevented from moving in the horizontal direction, thereby improving the stability after the connection between the pier body 1 and the base 2.

[0044] In some embodiments, the bracket body 32 is arranged parallel to the side surface of the pier column body 1. The connecting portion 34 is provided at both ends of the bracket body 32 in the circumferential direction of the pier column body 1 and is bent toward the outer peripheral side of the pier column body 1. The connecting portions 34 of adjacent limiting brackets 3 can be closely attached to each other. The connecting portion 34 is provided with a screw hole, and the screw holes of the connecting portions 34 of adjacent limiting brackets 3 are communicated. Furthermore, adjacent connecting portions 34 can be connected by fixing bolts, so that the limiting brackets 3 are connected to each other.

[0045] According to some embodiments of the present invention, in the direction from bottom to top, the diameter of the connecting column 21 gradually decreases. That is to say, the connecting column 21 is formed into a tapered structure with a smaller upper part and a larger lower part, so as to reduce the difficulty of the upper end of the connecting column 21 entering the connecting slot 11, and further reduce the assembly difficulty of the pier column body 1 and the base 2, which is beneficial to improving the connection efficiency of the pier column body 1 and the base 2.

[0046] According to some embodiments of the present invention, the outer peripheral surface of the bottom of the connecting column 21 abuts against the inner peripheral surface of the connecting slot 11. That is to say, the diameter of the bottom of the connecting column 21 is the same as the inner diameter of the connecting slot 11. Among them, when the diameter of the bottom of the connecting column 21 remains unchanged, the larger the inner diameter of the connecting slot 11, the larger the volume of the connecting slot 11 occupying the pier column body 1, the poorer the strength of the pier column body 1, and the poorer the stability of the pier column body 1; on the contrary, when the inner diameter of the connecting slot 11 remains unchanged, the smaller the diameter of the bottom of the connecting column 21, the fewer the connecting parts between the connecting column 21 and the pier column body 1, and the poorer the connection stability between the connecting column 21 and the pier column body 1. Therefore, setting the diameter of the bottom of the connecting column 21 to be the same as the inner diameter of the connecting slot 11 can prevent the connecting slot 11 from being set too large to reduce the stability of the pier column body 1, and at the same time can prevent the connecting parts between the connecting column 21 and the pier column body 1 from being too small to reduce the connection stability, so as to improve the stability of the pier column body 1 and the connection stability between the connecting column 21 and the pier column body 1.

[0047] According to some embodiments of the present invention, there are multiple connecting slots 11 and multiple connecting columns 21. The number of the multiple connecting slots 11 is the same as that of the multiple connecting columns 21 and they correspond to each other one by one. That is to say, the pier column body 1 can be connected to the multiple connecting columns 21 of the base 2 through the multiple connecting slots 11, so as to increase the connection positions between the pier column body 1 and the base 2, and further improve the connection reliability between the pier column body 1 and the base 2.

[0048] In some embodiments, the multiple connecting slots 11 and the multiple connecting columns 21 are arranged at intervals along the circumferential direction of the pier column body 1. That is to say, the pier column body 1 can be connected to the connecting columns 21 of the base 2 through the connecting slots 11 arranged at intervals along the circumferential direction of the pier column body 1, so as to realize the connection between the pier column body 1 and the base 2 at multiple different positions in the circumferential direction, and further improve the connection reliability between the pier column body 1 and the base 2.

[0049] According to some embodiments of the present utility model, grouting holes 12 communicating with the connection slots 11 are formed on the outer peripheral surface of the pier column main body 1. Therefore, concrete can enter the connection slots 11 through the grouting holes 12 to fill the gaps between the connection slots 11 and the connection columns 21. After the concrete solidifies, the connection reliability between the connection slots 11 and the connection columns 21 can be improved.

[0050] In some embodiments, the top of the connection column 21 is spaced apart from the inner bottom wall of the connection slot 11, and the grouting holes 12 are provided at the top of the connection slot 11, and the top of the connection column 21 is spaced apart from the inner bottom wall of the connection slot 11. Herein, the inner bottom wall of the connection slot 11 refers to the inner wall opposite to the upper end of the connection column 21 in the up-and-down direction, so as to avoid interference and damage between the connection column 21 and the connection slot 11 and improve the reliability of the connection column 21 and the connection slot 11. Moreover, the grouting holes 12 are located at the top of the connection slot 11, so that the concrete entering the connection slot 11 through the grouting holes 12 can gradually fill the gaps between the connection column 21 and the connection slot 11 from bottom to top by its own weight. Finally, the concrete can fill the gaps in the connection slot 11 except for the connection column 21, which is beneficial to improving the connection reliability between the connection column 21 and the connection slot 11. In addition, the connection slot 11 is arranged adjacent to the outer peripheral surface of the pier column main body 1. Therefore, the distance between the connection slot 11 and the outer peripheral surface of the pier column main body 1 can be shortened, so that the distance for the grouting holes 12 to convey concrete into the connection slot 11 can be shortened, facilitating the entry of concrete into the connection slot 11.

[0051] According to some embodiments of the present utility model, lifting rings 13 are provided on the pier column main body 1. Therefore, the pier column main body 1 can be lifted and moved through the lifting rings 13, so that the pier column main body 1 can be moved more conveniently, thereby improving the connection efficiency between the pier column main body 1 and the base 2.

[0052] In some embodiments, during the pouring process of the pier column main body 1, part of the lifting rings 13 are inserted into the pier column main body 1. After the pier column main body 1 is poured and formed, the lifting rings 13 can be fixedly connected to the pier column main body 1, that is, part of the lifting rings 13 are embedded in the pier column main body 1, so as to improve the connection reliability between the pier column main body 1 and the lifting rings 13.

[0053] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and the like should be understood in a broad sense.
