[0002] Ceramic relics have significant cultural and historical value, and the restoration of ceramic relics is of great significance. Figure 1 The figure shows a schematic diagram of the structure of a restored ceramic artifact. Prior to restoration, the artifact was broken into two residual parts 1', with the defective part 2' to be repaired located between the two residual parts 1'. Each residual part 1' has a large inner cavity and a fracture connecting to the large inner cavity. The maximum diameter of the large inner cavity is larger than the diameter of the fracture. The current method for restoring ceramic artifacts involves shaping a mold based on the contours of the defective part 2', passing a patching material through the mold to form a filling wall corresponding to the contours of the defective part 2', and then connecting the filling wall to the fractures of the two residual parts 1'. The two residual parts 1' of the restored ceramic artifact are connected only by the filling wall, resulting in low structural strength and reduced durability of the restored ceramic artifact.

[0005] The working principle of the present invention is as follows:

[0006] This skeleton is used in conjunction with ceramic cultural relics. The ceramic cultural relics include a residual part and a broken part to be repaired. The residual part is formed with a large head inner cavity and a fracture connected to the large head inner cavity. The maximum diameter of the large head inner cavity is larger than the diameter of the fracture, and the fracture of the residual part is connected to the broken part. When in use, the operating end of each steel wire rope is pulled from the side of the splicing end of the support column, so that the contact end of each supporting spring moves toward the retracting component, thereby causing several supporting springs to bend to form a claw-like structure. The steel wire rope is continued to be pulled so that the claw-like structure is compressed and the diameter size is reduced until the diameter size of the claw-like structure is smaller than the diameter size of the fracture. The pulling operation of the steel wire rope is stopped, and the extended end of the support column is passed through the fracture of the residual part so that the claw-like structure is placed as a whole in the large head inner cavity. Then, the steel wire rope is gradually released, and each supporting spring gradually rebounds under its own elastic action. The claw-like structure gradually unfolds. During this process, the depth of the support column extending into the inner cavity of the large head is adjusted so that the contact end of each supporting spring rests on the inner wall of the large head inner cavity. After the shape of the claw-like structure is adjusted, each steel wire rope is fixed to lock the shape of the claw-like structure. Then, the repair material is filled from the fracture into the inner cavity of the large head so that the support structure and the inner cavity of the large head are connected and fixed by the repair material. The part of the support structure exposed in the residual part is covered with the repair material to form a repair matrix. The repair matrix is connected to the fracture of the residual part, and the outer contour of the repair matrix is the target outer contour of the damaged part. Through this design, the repaired ceramic cultural relic has a higher structural strength, thereby increasing the durability of the ceramic cultural relic.

[0008] Furthermore, in the aforementioned skeleton for ceramic cultural relic restoration, each supporting spring piece is formed with a fixing hole, which is arranged close to the contact end; the mounting end of each steel wire rope is mounted and fixed on the fixing hole of the corresponding supporting spring piece.

[0009] Furthermore, as described above, in a skeleton for restoring ceramic cultural relics, the folding assembly includes a sleeve and a fixing bolt; the folding channel is formed between the two ends of the sleeve, and a fixing screw hole is formed on the outer peripheral surface of the sleeve, the fixing screw hole is connected to the folding channel, and the sleeve is mounted on the support column through the folding channel; one end of the fixing bolt passes through the fixing screw hole of the sleeve and is placed on the outer peripheral surface of the support column.

[0011] Furthermore, in the aforementioned skeleton for ceramic cultural relic restoration, the number of the supporting structures is two, the supporting columns of the two supporting structures are coaxially arranged, and the splicing ends of the supporting columns of the two supporting structures are spliced and assembled together.

[0012] Furthermore, in the aforementioned skeleton for ceramic cultural relic restoration, the operating ends of the steel cables of the two supporting structures are connected and fixed together one by one through an assembly part, and a plurality of assembly parts are arranged in sequence around the axis of the supporting column.

[0013] Furthermore, in the aforementioned framework for restoring ceramic cultural relics, the plurality of assemblies are staggeredly arranged along the direction surrounding the axis of the support column.

[0036] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figure 2 and Figure 3 The skeleton for ceramic cultural relic restoration of embodiment 1 includes a support structure 1, which includes a support column 11, a plurality of support springs 12, a plurality of steel wire ropes 13 and a retraction assembly 14; one end of the support column 11 is an insertion end, and the other end of the support column 11 is a splicing end; the plurality of support springs 12 are evenly arranged around the axis of the support column 11, and the support spring 12 is a long strip structure, one end of the support spring 12 is a mounting end, and the other end of the support spring 12 is a contact end, and the mounting end of the support spring 12 is connected to the insertion end of the support column 11; a retraction channel is formed on the retraction assembly 14, and the retraction assembly 14 passes through the retraction channel. The folding channel is sleeved on the support column 11; a steel wire rope 13 corresponds to a supporting spring 12, one end of the steel wire rope 13 is a connecting end, and the other end of the steel wire rope 13 is an operating end. The connecting end of the steel wire rope 13 is connected to the supporting spring 12 and is arranged close to the contact end of the supporting spring 12, and the operating end of the steel wire rope 13 is arranged from the side of the folding component 14 close to the end extending into the support column 11 through the folding channel of the folding component 14. The steel wire rope 13 applies a force to the supporting spring 12 so that the supporting spring 12 bends toward the direction of the folding component 14, so that a combination of several supporting springs 12 forms a hook-like structure.

[0039] The working principle of this embodiment is as follows:

[0040] This skeleton is used in conjunction with ceramic cultural relics. The ceramic cultural relics include a residual part and a broken part to be repaired. The residual part is formed with a large head inner cavity and a fracture connected to the large head inner cavity. The maximum diameter of the large head inner cavity is larger than the diameter of the fracture, and the fracture of the residual part is connected to the broken part. When in use, the operating end of each steel wire rope 13 is pulled from the side of the splicing end of the support column 11, so that the contact end of each supporting spring piece 12 moves toward the retracting component 14, thereby causing several supporting spring pieces 12 to bend to form a claw-like structure. The steel wire rope 13 is continuously pulled so that the claw-like structure is compressed and the diameter size is reduced until the diameter size of the claw-like structure is smaller than the diameter size of the fracture. The pulling operation of the steel wire rope 13 is stopped, and the inserted end of the support column 11 is passed through the fracture of the residual part so that the claw-like structure is placed as a whole in the large head inner cavity. Then, the steel wire rope 13 is gradually released, and each supporting spring piece 12 is gradually retracted under the action of its own elasticity. The claw-like structure gradually expands due to the gradual rebound. During this process, the depth of the support column 11 inserted into the inner cavity of the large head is adjusted so that the contact end of each supporting spring piece 12 is against the inner wall of the inner cavity of the large head. After the shape of the claw-like structure is adjusted, each steel wire rope 13 is fixed to lock the shape of the claw-like structure. Then, the repair material is filled from the fracture into the inner cavity of the large head so that the support structure 1 and the inner cavity of the large head are connected and fixed by the repair material. The part of the support structure 1 exposed to the residual part is covered with the repair material to form a repair matrix. The repair matrix is connected to the fracture of the residual part, and the outer contour of the repair matrix is the target outer contour of the defective part. Through such a design, the repaired ceramic cultural relics have a higher structural strength to increase the durability of the ceramic cultural relics.

[0041] like Figure 2 As shown, each support spring 12 is formed with a fixing hole, located near the contact end; the mounting end of each steel wire 13 is mounted and fixed to the fixing hole of the corresponding support spring 12. In actual use, support springs 12 of corresponding lengths are selected or cut according to the specifications of the large end inner cavity of the remaining portion. The fixing hole is formed in the support spring 12 by drilling a hole, and the mounting end of the support spring 12 is connected and fixed to the protruding end of the support column 11 by welding. The mounting end of the steel wire 13 passes through the fixing hole and is connected and fixed to the support spring 12 by tying or welding. Alternatively, the mounting end of the steel wire 13 is formed into a large end structure by knotting, welding a fixing head, etc., and the operating end of the steel wire 13 is sequentially passed through the fixing hole of the support spring 12 and the retraction channel of the retraction assembly 14. In this embodiment, a clamping head 131 is welded to the mounting end of the steel wire 13.

[0042] like Figure 2 and Figure 3As shown, the retraction assembly 14 includes two clamping members 141, two tightening bolts 142 and two tightening nuts 143; the two clamping members 141 are respectively placed on both sides of the support column 11, and the two ends of the two clamping members 141 are respectively spliced and assembled together by a tightening bolt 142 and a tightening nut 143, so that the two clamping members 141 enclose the retraction channel, and the tightening bolts 142 and the tightening nuts 143 are gradually tightened to gradually narrow the aperture of the retraction channel, so that each wire rope 13 is clamped and fixed between the retraction channel and the support column 11. When in use, the two clamping parts 141 are first assembled together by tightening bolts 142 and tightening nuts 143 and are sleeved on the support column 11. At this time, the tightening bolts 142 and the tightening nuts 143 are not tightened first, so that the wire rope 13 can freely pass through the retracting channel of the retracting component 14. During the adjustment of the shape of the hook-like structure, in order to prevent the wire rope 13 from dragging the retracting component 14 to slide, the retracting component 14 can be manually grasped and fixed; after the shape adjustment of the hook-like structure is completed, the tightening bolts 142 and the tightening nuts 143 are tightened, so that the retracting channel of the retracting component 14 gradually narrows, so that the wire rope 13 is clamped and fixed between the inner wall of the retracting channel and the outer peripheral surface of the support column 11, thereby fixing the wire rope 13.

[0043] Example 2

[0044] like Figures 4 to 7 This is a skeleton for repairing ceramic cultural relics according to Example 2. The difference between Example 2 and Example 1 is that: the number of the support structures 1 is two, the support columns 11 of the two support structures 1 are coaxially arranged, and the splicing ends of the support columns 11 of the two support structures 1 are spliced and assembled together. This embodiment is applied to ceramic cultural relics that have been broken into two residual parts, and the incomplete part of the ceramic cultural relic is between the fractures of the two residual parts. When in use, one support structure 1 corresponds to one residual part, and the hook-shaped structure of each support structure 1 is placed in the inner cavity of the large head of the corresponding residual part and after the shape is adjusted, the splicing ends of the support columns 11 of the two support structures 1 are spliced and assembled together by welding, and the repair matrix is provided on the part where the support columns 11 of the two support structures 1 are exposed to the corresponding residual part.

[0045] like Figure 4 and Figure 6 As shown, the outer circumferential surface of the support column 11 is formed with a plurality of reinforcing flanges 111. The plurality of reinforcing flanges 111 are arranged along the axial direction of the support column 11 and are located between the extending end of the support column 11 and the retracting assembly 14. The addition of the reinforcing flanges 111 increases the contact area between the support column 11 and the supplementary material in the inner cavity of the large end of the residual part, thereby making the connection between the support structure 1 and the residual part more stable.

[0046] like Figure 4 、 Figure 6 and Figure 7 As shown, the folding assembly 14 includes a sleeve 144 and two fixing bolts 145; the folding channel is formed between the two ends of the sleeve 144, and two fixing screw holes are formed on the outer peripheral surface of the sleeve 144. The two fixing screw holes are respectively located on both sides of the sleeve 144, and each fixing screw hole is connected to the folding channel. The sleeve 144 is sleeved on the support column 11 through the folding channel; one fixing bolt 145 corresponds to one fixing screw hole, and one end of the fixing bolt 145 passes through the fixing screw hole of the sleeve 144 and is placed on the outer peripheral surface of the support column 11. Compared with Example 1, the folding component 14 adopts the above-mentioned design, which can fix the folding component 14 relative to the support column 11. During the adjustment of the hook-shaped structure, the folding component 14 will not be dragged by the wire rope 13, and there is no need to manually grasp and fix the folding component 14. While the operation is more convenient, the folding component 14 can be set in the large head inner cavity of the residual part, thereby avoiding contact between the wire rope 13 and the cavity wall of the large head inner cavity, thereby improving the folding effect of the folding component 14 on the wire rope 13.

[0047] like Figure 4 、 Figure 5 and Figure 6 As shown, the operating ends of the steel wire ropes 13 of the two support structures 1 are connected and fixed together by an assembly 15, one for each. Several assembly 15 are arranged in sequence around the axis of the support column 11. In actual use, after the claw-shaped structure is adjusted, the length of the steel wire ropes 13 is cut, and the corresponding operating end assemblies 15 of the two steel wire ropes 13 are connected and fixed together, thereby securing each steel wire rope 13. The assembly 15 in this embodiment is a wire clamp. In actual use, the assembly 15 can also be a lead block connecting the two steel wire ropes 13. The provision of the assembly 15 makes it easier to connect and fix the operating ends of the two corresponding steel wire ropes 13.

[0048] like Figure 4 、 Figure 5 and Figure 6 As shown, several assemblies 15 are staggeredly arranged along the direction surrounding the axis of the support column 11. Through such a layout structure, the force structure between the skeleton and the repair matrix can be made more reasonable, and the connection between the skeleton and the repair matrix can be made more stable.

[0049] Example 3

[0050] Example 3 is a method for restoring a ceramic artifact, comprising a ceramic artifact, a frame, and a repair material. The ceramic artifact is broken into two residual parts, each of which has a large end cavity and a fracture communicating with the large end cavity. The maximum diameter of the large end cavity is larger than the diameter of the fracture. The defective part of the ceramic artifact to be repaired is located between the fractures of the two residual parts. The frame is the frame for restoring ceramic artifacts described in Example 2, and a supporting structure of the frame corresponds to a residual part. The operation steps of each supporting structure of the frame are as follows:

[0051] S1: Pull the operating end of each steel rope from the side of the support column splicing end, so that the contact end of each supporting spring moves toward the retracting assembly, thereby causing several supporting springs to bend to form a claw-like structure;

[0052] S2: Continue pulling the wire rope so that the hook-shaped structure is compressed and its diameter is reduced until the diameter of the hook-shaped structure is smaller than the diameter of the corresponding fractured portion of the residual portion, and stop pulling the wire rope;

[0053] S3: Pass the extending end of the support column through the corresponding fracture opening of the residual part, so that the entire hook-shaped structure is placed in the inner cavity of the large end of the corresponding residual part;

[0054] S4: Gradually releasing the steel wire rope, each supporting spring piece gradually rebounds under its own elastic action, causing the hook-shaped structure to gradually unfold. During this process, the depth of the supporting column extending into the inner cavity of the big head is adjusted so that the contact end of each supporting spring piece contacts the inner wall of the inner cavity of the big head;

[0055] S5: After the shape of the hook-shaped structure is adjusted, each steel wire rope is fixed to lock the shape of the hook-shaped structure;

[0056] S6: Filling the inner cavity of the large head with a patching material from the fracture opening so that the support structure and the inner cavity of the large head are connected and fixed by the patching material;

[0057] After each supporting structure is connected and assembled with the corresponding residual part, the splicing ends of the supporting columns of the two supporting structures are spliced and assembled together, and the parts of the two supporting columns of the skeleton exposed to the two residual parts are covered with patching materials to form a repair matrix. The repair matrix is connected to the fracture ends of the two residual parts, and the outer contour of the repair matrix is the target outer contour of the defective part.

[0058] The restoration material is a mixture of dental plaster, clay powder, and burlap; a mixture of talc, 509 glue, and burlap; or a mixture of talc, clay powder, 509 glue, and burlap. This formulation of restoration material ensures the restoration substrate closely resembles the original material of the ceramic artifact and exhibits excellent aging and weather resistance.

[0059] The outer surface of the repair matrix is coated with 509 glue to further improve the anti-aging and weather resistance of the repair matrix.
