Description

Technical Field

[0001] The present invention relates to the technical field of cultural relic restoration, in particular to a limestone cultural relic bonding mould and a limestone cultural relic bonding method. Background Art

[0002] China's grotto temples have a long history, are numerous, and feature rich content. They possess unique styles and distinct national characteristics, providing a wealth of valuable material for the study of ancient Chinese history, religion, art, folk customs, and social, political, and economic transformations, representing a non-renewable cultural relic resource. Due to my country's vast territory and vastly varying geographical and climatic conditions, grotto temples, as immovable cultural relics, have suffered varying degrees of damage to the rock mass and sculptures due to the long-term effects of natural forces and human activities. Specifically, grotto temples, constructed from limestone primarily composed of dolomite and calcite, are severely weathered due to their brittle nature, low rock strength, and subsequent infilling with cement. This has led to frequent defects such as localized defects and cracks, degrading the rock mass and causing the cracked rock mass to gradually fragment and fall off. This continuous process has resulted in layered delamination and collapse of the cliff face and the sculptures themselves, ultimately destroying and dismantling the grotto sculptures and their associated cultural relics.

[0003] At present, the main method of reinforcement and repair for weathering damages such as cracking and partial loss of limestone grotto temple rock masses and their cultural relics is to use anti-weathering reinforcement materials. Anti-weathering reinforcement materials generally include inorganic materials, organic materials, composite materials, and organic-inorganic hybrid materials. Among them, bonding reinforcement technology is one of the most important measures for weathering reinforcement and repair of limestone grotto temple rock masses and cultural relics. Current anti-weathering reinforcement materials have the advantages and disadvantages of both organic and inorganic materials. Specifically, organic materials have good bonding strength, but poor compatibility with limestone rock masses and cultural relics, and poor aging resistance. Inorganic materials have good aging resistance and compatibility, but suffer from the defect of less than ideal bonding strength. Summary of the Invention

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The purpose of the present invention is to provide a limestone cultural relic bonding mold and a limestone cultural relic bonding method to solve the problems existing in the above-mentioned prior art, and to extend the maximum service life of the existing limited available bonding and reinforcement materials for cultural relic defects such as limestone cracks and local defects, thereby effectively improving and enhancing the service life and lifespan of the existing bonding and reinforcement materials.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] like Figure 1-8As shown, this embodiment provides a limestone cultural relic bonding mold 100, including a shaping mold 1 and a first sealing component 101. The shaping mold 1 has a sealing surface 105. The first sealing component 101 can be fixedly connected to the sealing surface 105, and the first sealing component 101 protrudes from the sealing surface 105. The first sealing component 101 can extend from the outside of the to-be-bonded cavity 7 of the to-be-bonded workpiece into the to-be-bonded cavity 7, and the first sealing component 101 can seal the to-be-bonded cavity 7. A first mold cavity 102 is formed between the shaping mold 1 and the to-be-bonded workpiece. The first mold cavity 102 is formed by the gap between the first sealing component 101 and the to-be-bonded cavity 7 or is surrounded by the inner side wall of the first sealing component 101. Specifically, when the to-be-bonded cavity 7 is in the form of a groove on the to-be-bonded workpiece (such as a crack), the first mold cavity 102 is formed by the gap between the first sealing component 101 and the to-be-bonded cavity 7. When the bonded part is broken into the first bonded part 3 and the second bonded part 4, the bonded cavity 7 is the space occupied by the bonding layer between the first bonded part 3 and the second bonded part 4. The shaping mold 1 is provided with a first injection hole connected to the first mold cavity 102. The first injection hole is used to fill the organic adhesive material into the first mold cavity 102 and form an organic adhesive material layer 5. The space occupied by the first sealing part 101 in the bonded cavity 7 can form a bonding groove 8. The bonding groove 8 is used to fill the inorganic adhesive material and form an inorganic adhesive material layer 6. The inorganic adhesive material layer 6 and the inner wall of the bonded cavity 7 can completely wrap the organic adhesive material layer 5. The limestone cultural relic bonding mold 100 provided in this embodiment first seals the cavity to be bonded 7 through the first sealing component 101 to form a first mold cavity 102, and fills the first mold cavity 102 with an organic bonding material to form an organic bonding material layer 5. Then, the shaping mold 1 and the first sealing component 101 are separated from the object to be bonded. At this time, the space occupied by the first sealing component 101 in the cavity to be bonded 7 can form a bonding groove 8, and the inorganic bonding material layer 6 is filled into the bonding groove 8. The inorganic bonding material layer 6 and the inner wall of the cavity to be bonded 7 can completely wrap the organic bonding material layer 5.The limestone cultural relic bonding mold 100 utilizes both organic and inorganic bonding materials to bond cultural relics, giving full play to the advantages of high bonding strength of organic bonding materials and good aging resistance and compatibility of inorganic bonding materials. It can extend the maximum service life of the existing limited available bonding reinforcement materials for cultural relic defects such as limestone cracks and local defects, and effectively improve and enhance the service life and lifespan of existing bonding reinforcement materials. Compared with the existing method of seeking diverse bonding reinforcement materials, it provides a new approach to the bonding reinforcement technology for weathering protection and restoration of limestone rock masses and cultural relics. At the same time, since organic bonding materials are more susceptible to weathering, the inorganic bonding material is arranged on the outer ring of the organic bonding material, which can reduce the degree of weathering of the organic bonding material in the inner ring. The appearance of the inorganic bonding material is more similar to that of the limestone rock mass and cultural relics, which can improve the aesthetics of the repaired limestone rock mass and cultural relics.

[0040] In this embodiment, the shaping mold 1 has an inner cavity that runs through the shaping mold 1, and the inner side wall of the inner cavity is a sealing surface 105. The inner cavity of the shaping mold 1 is used to sleeve the workpiece to be bonded, and the inner side wall of the shaping mold 1 can match the outer wall of the part of the workpiece to be bonded that is sleeved in the inner cavity, so that the shaping mold 1 can limit the movement of the workpiece to be bonded along the direction perpendicular to the extension direction of the inner cavity, thereby ensuring that there will be no displacement between the first sealing component 101 and the workpiece to be bonded, thereby ensuring the bonding effect.

[0041] In this embodiment, the first sealing component 101 is annular, and the cavity to be bonded 7 is annular. The first sealing component 101 can be fully extended into the cavity to be bonded 7. The inner cavity portions located on both sides of the first mold cavity 102 are respectively a first accommodating cavity 103 and a second accommodating cavity 104. The first accommodating cavity 103 is used to accommodate the first component to be bonded 3, and the second accommodating cavity 104 is used to accommodate the second component to be bonded 4. The two ends of the first sealing component 101 can respectively contact the end of the first component to be bonded 3 close to the second accommodating cavity 104 and the end of the second component to be bonded 4 close to the first accommodating cavity 103. The space between the end face of the first component to be bonded 3 close to the second accommodating cavity 104, the end face of the second component to be bonded 4 close to the first accommodating cavity 103, and the inner sidewall of the first sealing component 101 constitutes the first mold cavity 102. The first sealing component 101 can restrict the movement of the first component to be bonded 3 toward the second accommodating cavity 104, and the first sealing component 101 can restrict the movement of the second component to be bonded 4 toward the first accommodating cavity 103. The bonding of the first component to be bonded 3 and the second component to be bonded 4 is completed by filling the first mold cavity 102 with organic adhesive material. Since the first mold cavity 102 is surrounded by the inner side wall of the first sealing component 101, and the bonding surfaces of the first component to be bonded 3 and the second component to be bonded 4 can respectively contact the two ends of the first sealing component 101, the projections of the first mold cavity 102 on the bonding surfaces of the first component to be bonded 3 and the bonding surfaces of the second component to be bonded 4 are located inside the outer edges of the corresponding bonding surfaces, that is, the organic adhesive material layer 5 bonds the middle part of the first component to be bonded 3 and the middle part of the second component to be bonded 4.

[0042] This embodiment further includes a second sealing component 2, which is capable of contacting the part to be bonded and sealing the bonding groove 8 and forming a second mold cavity. A second injection hole is provided on the second sealing component 2 or between the second sealing component 2 and the part to be bonded, which is capable of communicating with the second sealed cavity. The second injection hole is used to fill the second mold cavity with an inorganic adhesive layer 6. The first part to be bonded 3 and the second part to be bonded 4 can be bonded into a single component via an organic adhesive layer 5. The second sealing component 2 can be mounted outside the single component. The outer wall of the organic adhesive layer 5 in the single component, the outer wall of the first part to be bonded 3 near the second part to be bonded 4, and the outer wall of the second part to be bonded 4 near the first part to be bonded 3 form an annular groove. The second sealing component 2 can completely cover the annular groove and seal the annular groove of the single component. Inorganic adhesive material is injected into the annular groove through the second injection hole, completing the bonding of the outer rings of the first part to be bonded 3 and the second part to be bonded 4.

[0043] In this embodiment, the shaping mold 1 is a silicone mold, and the first sealing component 101 is a sealing tape. As a preferred embodiment, when the sealing tape is bonded to the outer wall of the integral component, a gap is left above the annular groove to form a first injection hole, which helps to simplify the structure of the second sealing component 2.

[0044] In this embodiment, the first accommodating cavity 103 and the second accommodating cavity 104 are both cylindrical. The inner wall of the first accommodating cavity 103 can completely contact the outer wall of the first component to be bonded 3, and the inner wall of the second accommodating cavity 104 can completely contact the outer wall of the second component to be bonded 4, thereby effectively limiting and fixing the first component to be bonded 3 and the second component to be bonded 4, ensuring the stability of the bonding. As an embodiment, the first sealing component 101 is annular, and the first mold cavity 102, the first accommodating cavity 103, and the second accommodating cavity 104 are cylindrical.

[0045] It should be noted that the limestone cultural relic bonding mold 100 provided in this embodiment is not only suitable for the bonding reinforcement of cracks and local defects in the protection of limestone stone cultural relics, but also provides a new method and idea for the bonding reinforcement research and engineering application of other types of stone cave temples.

Place the first component to be bonded 3 in the first accommodating cavity 103 of the shaping mold 1, and make the upper end surface of the first component to be bonded 3 contact the lower end surface of the first sealing component 101, fill the first mold cavity 102 with organic adhesive material through the upper end opening (first injection hole) of the second accommodating cavity 104, and place the second component to be bonded 4 in the second accommodating cavity 104 of the shaping mold 1, so that the first component to be bonded 3 and the second component to be bonded 4 are bonded into an integral part; S2. Separate the shaping mold 1, the first sealing component 101 and the integral part, connect the second sealing component 2 to the integral part, and make the second sealing component 2 seal the annular groove between the first component to be bonded 3 and the second component to be bonded 4, and inject inorganic adhesive material into the annular groove through the second injection hole on the second sealing component 2. It should be noted that the shaping mold 1 can be set as a multi-petal mold to facilitate the removal of the shaping mold 1 from the integral part.

[0062] The limestone cultural relic bonding method provided in this embodiment uses an organic bonding material to bond the middle portion of the bonding surface of the first component to be bonded 3 and the middle portion of the bonding surface of the second component to be bonded 4 using a shaping mold 1, and uses an inorganic bonding material to bond the outer ring of the bonding surface of the first component to be bonded 3 and the outer ring of the bonding surface of the second component to be bonded 4 using a second sealing component 2. That is, the cultural relic is bonded layer by layer in two steps using organic and inorganic bonding materials, giving full play to the advantages of high bonding strength of organic bonding materials and good aging resistance and compatibility of inorganic bonding materials. It can extend the maximum service life of the existing limited available bonding reinforcement materials for cultural relic diseases such as limestone cracks and local defects, and effectively improve and enhance the service life and lifespan of existing bonding reinforcement materials. Compared with the existing method of seeking a variety of bonding reinforcement materials, this embodiment provides a new approach to bonding reinforcement technology for weathering protection and restoration of limestone rock masses and cultural relics.

[0064] In this embodiment, S2 further includes: after injecting the inorganic adhesive material into the annular groove, sealing the second injection hole, applying pressure to the first component to be bonded 3 directed toward the second component to be bonded 4, and applying pressure to the second component to be bonded 4 directed toward the first component to be bonded 3, until the inorganic adhesive material is initially solidified. This helps to increase the bonding strength and improve the bonding effect of the second adhesive material.

[0065] As a preferred embodiment, in steps S1 and S2, the pressure applied to the first component to be bonded 3 is perpendicular to the bonding surface of the first component to be bonded 3, and the pressure applied to the second component to be bonded 4 is perpendicular to the bonding surface of the second component to be bonded 4; more preferably, the first component to be bonded 3 and the second component to be bonded 4 are clamped by an F-type fixture to achieve the application of pressure.

[0066] In this embodiment, S2 further includes: after the inorganic adhesive material is initially cured, removing the second sealing component 2 from the integral component, and placing the integral component in an environment of a certain temperature and humidity for curing until the inorganic adhesive material is completely cured to form an inorganic adhesive material layer 6. The temperature and humidity of the curing environment can be set according to the material selection, etc.

[0067] In this embodiment, S2 further includes: before connecting the second sealing component 2 to the integral component, wetting the inner wall of the annular groove. As a preferred embodiment, pure water is used to wet the inner wall of the annular groove.

[0068] In this embodiment, S1 also includes: before bonding the first component to be bonded 3 and the second component to be bonded 4, obtaining the shape and size of the first component to be bonded 3 and the second component to be bonded 4, obtaining the shape and size of the first sealing component 101, the first accommodating cavity 103 and the second accommodating cavity 104 according to the shape and size of the first component to be bonded 3 and the second component to be bonded 4, and making a shaping mold 1.

[0069] The following is an example of the limestone sample at the grotto temple site. The specific bonding method is as follows:

[0070] (1) According to the diameter of the sample obtained by drilling the core of the limestone at the grotto temple site, the size of the silicone shaping mold 1 to be used for bonding reinforcement is determined. The size determination includes: the shape, height, thickness of the shaping mold 1, the thickness and height of the first sealing component 101, and the silicone shaping mold 1 required for the test is obtained by indoor liquid silicone shaping; here, the shape of the silicone shaping mold 1 is cylindrical, with a height of 45 mm, an inner diameter of 54 mm, and a thickness of 10 mm; the outer convex height of the first sealing component 101 is 5 mm, the thickness is 5 mm, and it is located in the middle of the entire cylinder.

[0071] (2) A limestone sample with a diameter of 54 mm and a height of 20 mm is placed at either end of the silicone molding mold 1 and is considered the lower limestone sample (the first component to be bonded 3). An organic adhesive is bonded to the central concave surface (the first mold cavity 102) formed by the first sealing component 101 and the limestone sample. The organic adhesive forms a first adhesive layer with a circular surface diameter of 44 mm and a thickness of 5 mm. The first adhesive layer is consistent with the height of the first sealing component 101.

[0072] (3) Another limestone specimen with a diameter of 54 mm and a height of 20 mm was bonded to the organic adhesive material layer 5. After bonding was completed, the upper and lower limestone specimens were clamped using an F-type fixture, and vertical pressure was applied to increase the bonding force. The specimen was then allowed to stand. After the organic adhesive material solidified, the F-type fixture and the silicone molding mold 1 were removed.

[0073] (4) Use sealing tape to seal the 5mm high and 5mm thick groove (annular groove) left by the silicone molding mold 1, and reserve a second injection hole. Use pure water to moisten the inner wall of the annular groove in advance, and use a syringe to inject the inorganic adhesive material with the required water-cement ratio into the annular groove from the reserved second injection hole. The inorganic adhesive material must be injected full and free of bubbles. After the injection is completed, the second injection hole is sealed; use an F-type fixture to apply pressure and clamp the sample completed by wrapping the inorganic adhesive material with the organic adhesive material for the second time, and wait for the sample to initially solidify.

[0074] (5) After the inorganic adhesive material has initially solidified, the surface sealing tape is removed and the specimen is cured in a constant temperature and humidity chamber at 20°C and 95% relative humidity until the inorganic adhesive material is completely solidified. This completes the entire technical process of bonding limestone specimens with inorganic adhesive wrapped around organic adhesive.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
