Description

Technical Field

[0001] The present invention relates to the technical field of cultural relics protection, and in particular to a mural hollowing disease simulation mold and method. Background Art

[0002] Mural hollowing refers to a phenomenon in which the base layer of a mural partially detaches from its support, while the surrounding area of ​​the detached portion remains connected to the support. Hollowing is one of the main defects of ancient murals, and the most common protection method currently is grouting reinforcement. According to the "Guidelines for the Protection of Chinese Cultural Relics and Historic Sites," which requires that "all new materials and processes must undergo preliminary testing to prove their effectiveness and be harmless to the long-term preservation of cultural relics and historical sites before they can be used," grouting materials must undergo preliminary testing before use, usually including laboratory and on-site evaluations. During laboratory evaluation, in addition to evaluating the properties of the grouting material itself, hollowing must also be simulated before evaluating the protective effect.

[0003] The current simulation method of hollowing disease is mainly to smear a certain width and thickness of mud on the edge of the pre-made ground plaster test block, smear the same thickness of mud at a certain distance from the middle, and then stick this prepared ground plaster test block to the prepared earth wall or stone wall, and finally obtain hollowing disease. However, the hollowing made by this method is different from the actual mural hollowing. Usually, the mural hollowing is due to the loss or weakening of the adhesion between the ground plaster layer and the support, causing the two to separate. Generally, there will be a certain degree of deformation and bulging of the ground plaster layer, and the hollowing shape is irregular. There is less ground plaster layer and the support body that continue to be connected in the center of the hollowing, and usually the distance between the ground plaster layer and the support body is not uniform. In addition, the hollowing disease made by the existing method may also have the problem that the adhesion of the original surrounding ground plaster is not strong due to subsequent pasting.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a mural hollowing disease simulation mold and method, which can cause the ground layer to deform and produce hollowing diseases, effectively simulating the mural hollowing disease phenomenon.

[0006] The technical solution of the present invention is achieved as follows:

[0007] According to one aspect of the present invention, a mold for simulating hollowing defects in murals is provided.

[0008] The mural hollowing disease simulation mold includes: a base; an elastic membrane connected to the periphery of the base and used for supporting the ground layer, and one end of the elastic membrane has a through opening for gas and liquid to flow in and out; a accommodating cavity located between the base and the elastic membrane and used for supporting gas and liquid; a sealing member adapted to the through opening and used for sealing the through opening; a fixing anchor located in the elastic membrane and used for fixing the elastic membrane together with a liquid setting agent after solidification; a pull rope connected to the inside of the elastic membrane, and extending out of the through opening after passing through the accommodating cavity.

[0009] Wherein, the base is a flexible base.

[0010] Wherein, the elastic membrane is an elastic hydrophobic membrane.

[0011] Wherein, the outer surfaces of the base and the elastic membrane have fine mesh patterns.

[0012] Wherein, the fixing anchors are staggered and distributed between the base and the inner wall of the elastic membrane.

[0013] Wherein, the base, the elastic membrane, the fixing anchor and the pull rope are an integrally formed structure.

[0014] Wherein, the thickness of the base is greater than the thickness of the elastic membrane.

[0015] According to another aspect of the present invention, a method for simulating mural hollowing defects is provided, which is used for the above-mentioned mural hollowing defect simulation mold.

[0016] The mural hollowing disease simulation method includes:

[0017] Adding a liquid setting agent into the containing cavity, and curing the mural hollowing disease simulation mold with the liquid setting agent added thereto;

[0018] After the liquid setting agent is cured, the mural hollowing disease simulation mold is fixed on the mural support, and the ground paste is applied on the elastic membrane, leaving the through opening position blank without applying the ground paste;

[0019] After the ground layer is slightly dry, a proper amount of water or heating is introduced into the containing cavity to dissolve the curing setting agent; and the dissolved setting agent is discharged;

[0020] Introducing gas into the accommodating cavity to expand the elastic membrane to a predetermined hollow size, and releasing the gas after the floor covering is completely dry;

[0021] Pulling the drawstring separates the mold from the mural ground and the support and pulls it out from the ground opening.

[0022] Wherein, the support body is a rammed earth wall or a stone wall.
