[0002] Many ancient buildings in China have a long history, and with their unique style and historical significance, they occupy an important position in the history of world architecture and have extremely high artistic achievements and scientific value. However, in the process of preservation over the years, ancient buildings have suffered varying degrees of damage due to the destruction of human and natural forces. The most common damage is the deformation, decay and cracking of the wooden structure pillars of ancient buildings. If not repaired in time, the entire ancient building may collapse due to uneven force.

[0003] The utility model with authorization announcement number CN221168834U provides a support device for repairing the column base of an ancient wooden structure building. A first connecting mechanism is used to connect two groups of first assembly frames together, and a second connecting mechanism is used to connect two groups of second assembly frames together. A personnel adjusts the height of the second assembly frame using a height adjustment mechanism, and then uses a column squeezing mechanism to squeeze the outer surface of the column base, thereby providing support for the column base of the ancient wooden structure building. Then, the personnel scrape the damaged parts on the column base and perform repair operations.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] See also Figure 1 As shown, one of the purposes of this embodiment is to provide a temporary supporting device for repairing ancient buildings, including a first upper frame 1, a second upper frame 2 is arranged on one side of the first upper frame 1, a first lower frame 3 and a second lower frame 4 are arranged below the first upper frame 1 and the second upper frame 2 respectively, the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 are all semi-annular structures, the outer arc surfaces of the first upper frame 1 and the second upper frame 2 are hinged with a plurality of supporting rods 5, the outer arc surfaces of the first lower frame 3 and the second lower frame 4 are hinged with a plurality of connecting rods 6, the lower ends of the connecting rods 6 are hinged to the positions of the supporting rods 5 near the middle sections, the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 are provided with a clamping mechanism 7, when the first upper frame 1 and the first lower frame 3 are placed on one side of the column foot, the second upper frame 1 and the second lower frame 2 are placed on the After the frame 2 and the second lower frame 4 are placed on the other side of the column foot, the first upper frame 1 and the second upper frame 2 are clamped together by the clamping mechanism 7, and the first lower frame 3 and the second lower frame 4 are clamped together. At this time, the column foot is located inside the circular area surrounded by the first upper frame 1 and the second upper frame 2, and the column foot is also located inside the circular area surrounded by the first lower frame 3 and the second lower frame 4. A number of support rods 5 and a number of connecting rods 6 are distributed in a ring shape, and the side walls of the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 are provided with a clamping mechanism 8. After the outer surface of the column foot is squeezed by the clamping mechanism 8, the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 are fixed to the outside of the column foot, and then the lower end of the support rod 5 is touched to the ground, so that the device can provide support for the column foot, which is convenient for workers to repair the column foot.

[0023] In order to enable the clamping mechanism 8 to squeeze the outer surface of the column foot, the structure of the clamping mechanism 8 is detailed below. Figure 2The clamping mechanism 8 includes four second threaded rods 83 respectively threadedly connected to the side walls of the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4. The second threaded rod 83 is rotatably connected to a clamping plate 81 at one end close to the clamping block 71. A plurality of guide rods 82 are fixedly connected to one side of the clamping plate 81 close to the second threaded rod 83. One end of the plurality of guide rods 82 slides through the side walls of the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 respectively. The guide rods 82 are horizontally arranged so that the clamping plate 81 can only be horizontally moved along the axis direction of the guide rods 82. Move, after the column foot is located inside the circular area surrounded by the first upper frame 1 and the second upper frame 2, and also inside the circular area surrounded by the first lower frame 3 and the second lower frame 4, rotate the four second threaded rods 83 in succession, and through the threaded connection between the second threaded rods 83 and the frame body, the second threaded rods 83 drive the clamping plates 81 to move horizontally toward the column foot until the four clamping plates 81 are in close contact with the outer surface of the column foot, and the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 can be fixed to the outside of the column foot, so that the device provides support for the column foot.

[0024] By keeping the support rod 5 in a vertical state, the space occupied by the device can be reduced, and the transportation and storage of the device can be facilitated. However, when the lower end of the support rod 5 in the vertical state touches the ground, the support surface of the device on the ground will be smaller, and the support of the device to the column foot is not stable enough. To solve this problem, when the clamping mechanism 7 clamps the first upper frame 1 and the second upper frame 2, and clamps the first lower frame 3 and the second lower frame 4, the clamping mechanism 7 will increase the distance between the first upper frame 1 and the first lower frame 3, and the distance between the second upper frame 2 and the second lower frame 4. Since the connecting rod 6 is arranged in an inclined manner, and the end of the connecting rod 6 close to the clamping plate 81 is higher, and the end away from the clamping plate 81 is lower, when the distance between the frame located below and the frame located above increases, the frame located below will drive the connecting rod 6 to flip over, and the flipped connecting rod 6 pushes the support rod 5 in a direction away from the frame, so that the support rod 5 flips in a direction away from the frame. After the lower ends of the flipped support rods 5 touch the ground, the support surface of the device on the ground can be expanded, so that the support of the device to the column foot is more stable.

[0025] In order to increase the distance between the first upper frame 1 and the first lower frame 3, and the distance between the second upper frame 2 and the second lower frame 4 while clamping the first upper frame 1 and the second upper frame 2, and the first lower frame 3 and the second lower frame 4, the structure of the clamping mechanism 7 is detailed as follows. Figure 2 , Figure 3 and Figure 4The clamping mechanism 7 includes a clamping block 71 fixedly connected to one end of the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4. The other ends of the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 are provided with a clamping slot 72. When the positions of the first upper frame 1, the second upper frame 2, the first lower frame 3 and the second lower frame 4 are adjusted, the clamping block 71 on the first upper frame 1 is slidably set in the clamping slot 72 on the second upper frame 2, the clamping block 71 on the second upper frame 2 is slidably set in the clamping slot 72 on the first upper frame 1, the clamping block 71 on the first lower frame 3 is slidably set in the clamping slot 72 on the second lower frame 4, and the clamping block 71 on the second lower frame 4 is slidably set in the clamping slot 72 on the first lower frame 3. After that, the first upper frame 1 and the second upper frame 2 are restricted from being separated due to relative vertical movement, and the first lower frame 3 and the second lower frame 4 are restricted from being separated due to relative vertical movement. At the same time, when one frame moves vertically, the cooperation of the clamping block 71 and the clamping slot 72 will drive the other frame on the same side to move vertically synchronously.

[0026] When the locking cam 75 is in the closed position, the locking cam 75 is in the closed position, and the locking cam 75 is in the closed position, so that the locking cam 75 can be locked. The threaded connection of the side wall of the frame 2 allows the second upper frame 2 to move vertically along the axial direction of the extension rod 75 in the direction away from the second lower frame 4. The second upper frame 2 drives the first upper frame 1 to move synchronously through the cooperation of the clamping block 71 and the clamping slot 72, so that the distance between the second upper frame 2 and the second lower frame 4 increases, and the distance between the first upper frame 1 and the first lower frame 3 increases. At this time, the distance between the upper end of the extension rod 75 and the first upper frame 1 and the second upper frame 2 is reduced, so that the vertical section of the locking frame 76 is inserted into the interior of the matching groove 74 and the locking groove 73, thereby restricting the clamping block 71 from moving out of the interior of the clamping slot 72, clamping the first upper frame 1 and the second upper frame 2, and clamping the first lower frame 3 and the second lower frame 4, so that the device can provide support for the column foot, and at the same time, several support rods 5 are flipped in the direction away from the frame body, expanding the supporting surface of the device on the ground, and making the device support the column foot more stable.
