[0017] The utility model is described in detail below in connection with the drawings and examples.

[0018] The anti -seismic ancient building stand column, such as Figures 1-4As shown, including the column 1, the bottom of the column 1 is integrally formed with a fixed platform 2, the fixed platform 2 is fixed inside the ground instead of the column 1, and the cross-sectional area of the fixed platform 2 is greater than that of the column 1, thus increasing the stable fixation of the fixed platform 2 inside the ground, the top surface of the column 1 is integrally formed with a weight block 12, the shaking degree of the higher place is usually larger when the earthquake occurs, therefore the weight block 12 is arranged to increase the weight of the higher place of the column 1, thereby reducing the vibration and damage of the higher place of the column 1 caused by the earthquake, a plurality of sliding grooves 3 are formed on the fixed platform 2, the plurality of sliding grooves 3 are located at the four vertices of the column 1, a plurality of sliding shafts 4 fixedly connected with the column 1 are slidingly connected in the sliding grooves 3, the position of the sliding shaft 4 is fixed to ensure that the column 1 can move stably under the driving of the sliding shaft 4, thereby reducing the situation that the column 1 tilts during movement, the sliding shaft 4 is slidingly connected on the central axis of the length and width direction of the sliding groove 3, the force exerted by the earthquake on the column 1 will make it slide in different directions in the sliding groove 3 under the driving of the sliding shaft 4, so that the force received by the column 1 will be gradually consumed in these movements, thereby ensuring the anti-seismic effect of the column 1, a plurality of limiting strips 5 are slidingly connected on the fixed platform 2, the limiting strips 5 abut against the outer peripheral wall and the two top surfaces of the sliding shaft 4, so as to reduce the situation that the limiting strips 5 slide along the sliding groove 3 under the action of the sliding shaft 4 in the initial state, thereby ensuring the stable placement of the column 1 on the fixed platform 2.

[0019] As shown in Figures 1-4 , the fixed platform 2 is provided with a through groove 11 communicating with the sliding groove 3, and the limiting strips 5 are slidingly connected on the inner wall of the through groove 11, the length of the limiting strips 5 is greater than the height of the fixed platform 2, so that the limiting strips 5 can be fixed deeper in the ground, and the through groove 11 is provided to ensure the vertical fixation of the limiting strips 5, and the structural strength of the limiting strips 5 is less than that of the supporting rod 10, when an earthquake with a level greater than the anti-seismic level of the column 1 itself occurs, the limiting strips 5 with lower structural strength will first break, since the limiting strips 5 are not fixed with the column 1, when the limiting strips 5 break, the limiting strips 5 located in the fixed platform 2 will slide downward along the through groove 11 to lose the limitation of the sliding shaft 4, so that the sliding shaft 4 can slide on the fixed platform 2 under the thrust of the earthquake to offset a part of the impact force received by the column 1, thereby further enhancing the shock isolation and anti-seismic effect of the column 1.

[0020] As shown in Figure 1 and Figure 3As shown, the bottom surface of the column body 1 is provided with a receiving groove 6 at the same position as the sliding shaft 4, and the top surface of the sliding shaft 4 is integrally formed with a connecting block 7, which is fixedly connected with the inner wall of the receiving groove 6. The provision of the receiving groove 6 provides a stress space between the column body 1 and the sliding shaft 4, and the height of the connecting block 7 is greater than the diameter of the sliding shaft 4, thereby ensuring that the column body 1 can stably slide with the sliding shaft 4, reducing the situation that the connecting block 7 is pulled out of the column body 1. The cross-sectional area of the receiving groove 6 is equal to that of the sliding shaft 4, reducing the situation that the column body 1 cannot slide with the rotating shaft due to the relative sliding between the connecting block 7 and the column body 1, and ensuring the stable use of the structure.

[0021] As shown in Figure 1 , Figure 3 and Figure 4 , the two side walls of the sliding groove 3 in the length direction are provided with sliding channels 8, and the connecting shaft 9 is slidably connected in the sliding channels 8. The provision of the sliding channels 8 ensures that the connecting shaft 9 can slide horizontally in the sliding groove 3, reducing the situation that the column body 1 fixedly connected with the sliding shaft 4 is inclined. The connecting shaft 9 includes a fixed segment and a plurality of telescopic segments, and the fixed segment is located between adjacent telescopic segments. The sliding shaft 4 is fixedly connected to the outer peripheral wall of the fixed segment. The telescopic segments are provided as telescopic rods. The provision of the sliding channels 8 provides a channel for the sliding of the connecting shaft 9 in the width direction of the fixed platform 2. Due to the provision of the telescopic rods, when the fixed platform 2 is subjected to an impact force exerted by an earthquake, the telescopic rods will deform by expansion and contraction along with the impact force, thereby bringing the sliding shaft 4 and the column body 1 to reciprocate along the length direction of the fixed platform 2. Through the provision of the sliding channels 8 and the sliding shaft 4, no matter which direction the impact force exerted by the earthquake on the column body 1, there is always a space for the column body 1 to move on the fixed platform 2, thereby dispersing the impact force received by the column body 1. In addition, the provision of the sliding groove 3 also limits the range of movement of the column body 1, reducing the situation that the column body 1 is pulled out of the fixed platform 2 due to the excessive range of movement.

[0022] As shown in Figure 1 , Figure 3 and Figure 4 , a plurality of support rods 10 are fixedly connected in the receiving groove 6 and abut against the bottom surface of the sliding groove 3. The support rods 10 are arranged in a staggered manner with the connecting shaft 9 and the sliding shaft 4. The structural strength of the support rods 10 is greater than that of the limiting strips 5. The provision of the support rods 10 increases the stress points of the column body 1 on the fixed platform 2. Since the support rods 10 are not fixedly connected with the top surface of the sliding groove 3, the support rods 10 can also move along with the column body 1 during an earthquake while ensuring the supporting effect on the column body 1, thereby ensuring the stable use of the structure.

[0023] Working principle: in the initial state, the restriction bar 5 is in contact with the inner wall of the sliding shaft 4 and extends into the bottom surface inner wall, when the earthquake with a level greater than the anti-seismic level of the column body 1 itself occurs, the restriction bar 5 extending to the ground will be broken, the broken restriction bar 5 will slide out of the sliding groove 3 along the through groove 11, thereby losing the restriction to the sliding shaft 4, therefore, when the fixed platform 2 and the column body 1 are subjected to the impact force exerted by the earthquake, the column body 1 will slide along the length direction or the width direction of the sliding groove 3 under the action of the sliding shaft 4 and the telescopic rod, thereby dispersing the impact force received by the column body 1.

[0024] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application can also be considered as the protection scope of the present application.
