Description

Technical Field

[0001] This invention relates to the production of antique-style objects, specifically to a method for processing components for the roof of an antique building. Background Technology

[0002] The development of replicas of traditional Chinese architecture has been significantly hindered by the inherent fire-resistance of wooden structures and the extreme difficulty of construction. Later, cast-in-place concrete structures were adopted, allowing for one-time casting. However, this method results in significant dimensional inaccuracies, affecting the overall appearance, and the long casting time leads to excessively long processing times. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] The purpose of this invention is to provide a method for processing components of antique-style building roofs, in order to solve the problem of excessively long processing time for existing antique-style roofs.

[0005] To achieve these objectives and other advantages according to the present invention, the following is provided:

[0006] A method for processing roof components for antique-style buildings includes the following steps:

[0007] Step S1: Obtain the roof mold and apply a release agent to the mold;

[0008] Step S2: Spray the first layer of fabric to a thickness of 2-3mm and let it dry; spray the second layer of fabric to a thickness of 4-6mm and let it dry.

[0009] Step S3: Spray the first layer of backing material, compact it, and place the installation component; spray the second layer of backing material, compact it, and place ...

[0010] Step S4: After air-drying indoors for 8-10 hours, demold to obtain the component.

[0011] Furthermore, in step S1, the process of applying the release agent to the mold is as follows: apply the first layer of wax to the mold and let it stand for 8-12 minutes, then apply the second layer of wax and let it stand for 8-12 minutes; apply the first layer of PVA and let it stand for 10-14 minutes, then apply the second layer of PVA and let it stand for 10-14 minutes.

[0012] Furthermore, before applying the release agent to the mold, the surface roughness of the mold needs to be checked. If the roughness is greater than Ra1, the mold should be polished until the roughness is less than Ra1.

[0013] Furthermore, both the fabric and the backing material are made of GRC slurry, and the weight ratio of each component in the slurry is as follows: alkali-resistant glass fiber 4-6%, silicate cement 40-45%, water-reducing agent 0.4-0.9%, color powder 0.5-1%, retarder 0.3-0.8%, early strength agent 0.3-0.8%, and water 40-45%.

[0014] Furthermore, the processing of the GRC slurry is as follows: water-reducing agent, retarder, early strength agent and color powder are first added to water and stirred evenly, then silicate cement and alkali-resistant glass fiber are added and stirred evenly until a lumpy slurry is formed.

[0015] Furthermore, in step S2, after the first layer of fabric is sprayed, it is air-dried for 8-15 minutes; after the second layer of fabric is sprayed, it is air-dried for 15-20 minutes.

[0016] Furthermore, in step S3, after the first layer of backing material is compacted, it needs to be air-dried for 25-30 minutes; after the second layer of backing material is compacted, it needs to be air-dried for 35-40 minutes; and after the third layer of backing material is compacted, it needs to be air-dried for 20-25 minutes.

[0017] Furthermore, in step S4, the temperature is maintained at 15-20℃ during indoor air drying.

[0018] Furthermore, it also includes step S5: spraying 5-10% oxalic acid onto the component for uniform pickling.

[0019] The present invention has at least the following beneficial effects: the method of layer-by-layer spraying and rapid drying greatly accelerates the production speed; compared with natural stone and ordinary concrete, the total cost is reduced by about 20% when using GRC material.

[0020] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0026] A method for processing roof components of antique-style buildings, such as Figure 1 This includes the following steps:

[0027] Step S1: Obtain the roof mold and apply a release agent to the mold;

[0028] Step S2: Spray the first layer of fabric to a thickness of 2-3mm and let it dry; spray the second layer of fabric to a thickness of 4-6mm and let it dry.

[0029] Step S3: Spray the first layer of backing material, compact it, and place the installation component; spray the second layer of backing material, compact it, and place ...

[0030] Step S4: After air-drying indoors for 8-10 hours, demold to obtain the component.

[0031] This method primarily involves replicating existing ancient buildings, especially their roofs. Replicating the roof of an ancient building requires dividing it into several parts for component fabrication. Therefore, software is used for this initial division. Specifically, a 3D roof layout model is created, and a roof rendering model is built using BIM software, further dividing the roof into sections. Based on the detailed drawings produced from the BIM model layout, each face of the building's exterior is modeled and laid out. Simultaneously, based on the BIM model layout results and the different textures of each part, a 1:1 scale model of a section is created to verify its consistency with the rendering. These division methods are existing technologies and will not be elaborated upon further.

[0032] The roof mold is made of silicone. The production process is as follows: based on the division of the BIM software, the mold is made directly on the roof of the ancient building. After cleaning the roof, wooden boards are used as the edges around the perimeter. Then, silicone is introduced to create a sheet-like silicone mold.

[0033] After obtaining the mold, since the mold is part of the roof as described above, the product made by the present invention based on the mold is called a component, which is an antique roof component.

[0034] When making components, use wooden boards to create the edging, surrounding the sheet mold. The thickness of the wooden boards should be at least 25mm. Before processing, check that the mold is clean and has any quality markings.

[0035] Then apply a release agent to the mold to facilitate the demolding of subsequent components. Before applying the release agent, the smoothness of the mold should be checked to ensure the precision of the components. The surface roughness of the mold should also be checked. If the roughness is greater than Ra1, the mold should be polished until the roughness is less than Ra1. This is usually done manually with an abrasive cloth. The specific process for applying the release agent is as follows: apply the first layer of wax to the mold and let it stand for 8-12 minutes, then apply the second layer of wax and let it stand for 8-12 minutes; apply the first layer of PVA and let it stand for 10-14 minutes, then apply the second layer of PVA and let it stand for 10-14 minutes.

[0036] Next, component raw materials are added to the mold. Specifically, GRC slurry is used. GRC stands for Glass Fiber Reinforced Concrete. The slurry used in this invention is self-prepared and designed for use in replicating ancient buildings. The weight ratio of each component in the slurry is as follows: alkali-resistant glass fiber 4-6%, silicate cement 40-45%, water-reducing agent 0.4-0.9%, color powder 0.5-1%, retarder 0.3-0.8%, early-strength agent 0.3-0.8%, and water 40-45%. The processing of the GRC slurry is as follows: water-reducing agent, retarder, early-strength agent, and color powder are first added to water and stirred evenly. Then, silicate cement and alkali-resistant glass fiber are added and stirred thoroughly until a lumpy slurry is formed. Inorganic mineral color powder is used.

[0037] The specific process is as described above, involving two layers of fabric and three layers of backing material. After each layer is sprayed, it needs to be air-dried. After spraying the first layer of fabric, air-dry for 8-15 minutes; after spraying the second layer of fabric, air-dry for 15-20 minutes. After the first layer of backing material is compacted, air-dry for 25-30 minutes; after compacting the second layer of backing material, air-dry for 35-40 minutes; and after compacting the third layer of backing material, air-dry for 20-25 minutes. Figure 2 .

[0038] Next, while the components are air-dried indoors, the temperature should be maintained at 15-20℃. Once completed, they can be demolded. Figure 3The components are mostly complete, having taken approximately ten hours, which saves a significant amount of time compared to the monolithic concrete casting method. Furthermore, monolithic casting generally results in a lower level of precision.

[0039] Finally, spray 5-10% oxalic acid onto the components for uniform pickling to age them.

[0040] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
