Description

Technical Field

[0001] The utility model relates to a retro imperial kiln gold brick. Background Art

[0002] Imperial kiln gold bricks are treasures of traditional Chinese Han brickmaking. Favored by successive emperors since the Ming and Qing dynasties, they became a specialty product for imperial palace construction. During the Yongle reign of the Ming Dynasty, Emperor Chengzu Zhu Di relocated the capital to Beijing and embarked on a massive construction project for the Forbidden City. Recommended by craftsmen from the Xiangshan Kiln in Suzhou, the Lumu Brick Kiln attracted the attention of the Ministry of Works, which decided to "begin production in Suzhou, with the work assigned to sixty-three kiln operators in Changshu." Due to its superior quality, the kiln earned the praise of Emperor Yongle, who bestowed the name "Imperial Kiln." The so-called "gold bricks" is actually a refined name for large square bricks measuring 2.2, 2.5, and 1.7 feet square. The ancient text "Golden Brick Paving" explains: "Fine-grained square bricks fired exclusively for the imperial palace, with fine grain and a dense texture, create a resonant sound when struck, hence the name 'gold bricks.'"

[0003] Imperial kiln gold bricks are an important material for the floor decoration of retro buildings. The thickness of the Imperial kiln gold bricks in the existing technology is relatively large, usually around 8.5 cm, and the amount fired in the kiln at one time is small, which leads to a higher cost of Imperial kiln gold bricks and makes promotion more difficult.

[0004] Based on the above problems, we designed a retro imperial kiln gold brick that can reduce the thickness of the gold brick, increase the amount of gold bricks fired in one time, and is easy to lay. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a retro imperial kiln gold brick which can reduce the thickness of the gold brick, increase the amount of gold brick fired in one time in the kiln and is easy to lay.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

[0007] A retro imperial kiln gold brick comprises a gold brick body and a substrate structure paved on the ground, wherein the gold brick body is laid on the substrate structure, and a buffer sheet is provided between the gold brick body and the substrate structure.

Stepped holes are provided at the top of the substrate near the four corners, and threaded tubes are cast and fixed at the small holes of the stepped holes. The threaded tubes have built-in threads, and leveling bolts are fitted through the threaded tubes. The upper ends of the leveling bolts are sunk into the large holes of the stepped holes, and the lower ends of the leveling bolts are supported on the ground. The brick body is supported by the substrate.

[0009] Preferably, a groove is provided on the top of the substrate, the buffer sheet is placed in the groove, and the thickness of the buffer sheet after compression is greater than the depth of the groove.

[0010] Preferably, the buffer sheet is an elastic rubber sheet.

[0011] Preferably, an anti-slip groove is provided on the top of the buffer sheet.

[0012] Preferably, a buffer hole is injection-molded on the side of the buffer sheet, and the buffer hole passes through the buffer sheet transversely.

[0013] Preferably, a rubber strip is implanted in the buffer hole, the rubber strip is solid, the elastic force of the rubber strip is greater than the elastic force of the buffer sheet, and the rubber strip is interference fit with the buffer hole.

[0014] Preferably, a slurry feeding groove is provided on the side of the substrate.

[0015] Production process of Imperial Kiln Gold Bricks:

[0016] The production of Imperial Kiln Gold Bricks is a complex and delicate process that involves multiple steps and technical points. The following is a summary of the main production process of Imperial Kiln Gold Bricks:

[0017] Clay Selection: The soil for the imperial kiln's gold bricks must be of a unique quality, sourced from dry yellow clay found in the tombs northeast of the city. This clay is sticky, extremely fine, and free of sand and impurities. After selecting the clay, raw soil (or slurry) is collected from a depth of 3-4 meters below the surface. This process is known locally as "frozen soil." The soil is then piled in an open field for about six months, exposed to the elements, frost, rain, and snow, accelerating its decomposition. This process, commonly known as frozen soil, aims to eliminate lumps, ensure easy treading, and maintain a fine, sticky texture, ensuring the production of high-quality gold bricks.

[0018] Mud training: After finely breaking up the frozen soil piece by piece, add an appropriate amount of water to the mud pile, and let cows or people repeatedly step on the mud pile with their toes and feet to make the mud thick and clumpy, and train the mud. This step is commonly known as stepping on yellow mud.

[0019] Brick making: The brick making process is extremely complex, requiring significant labor and time. A local saying goes, "The yellow clay is like a mountain of gold; once you've made it, you're still a debt." Brick making involves filling the prepared clay into a mold for a gold brick, commonly known as "kneading the brick." The bricks are formed within the mold, requiring firm, barefoot treading, and completed in one go to ensure the clay is free of air holes. The surface is then cut with a wire bow and smoothed with a wooden board. Once the bricks are formed, two people carry them to a well-ventilated room and place them upright. Once the upper clay has hardened, the lower clay is flipped over. This process is repeated five to six times every few days until the surface is hard and white, and thoroughly dried in the shade, before they are ready for firing in the kiln.

[0020] Loading the kiln: The kiln environment for firing gold bricks is extremely demanding, requiring a large kiln. To prevent water from dripping directly onto the gold bricks during filtration, creating white spots and streaks, the bricks must be surrounded by ordinary bricks and tiles close to the kiln walls.

[0021] Kiln firing: This is the most critical step; even the slightest error can ruin an entire kiln of bricks. To ensure consistent temperatures within the kiln, the Lumu kiln chamber is taller than it is long, commonly known as a "mantou kiln." Once the bricks are in the kiln, they must be fired gently to prevent sudden flare-ups. The kiln temperature must be monitored constantly, and this control relies entirely on the kiln operator's experience. During the Qing Dynasty, firing time was significantly shortened, requiring only 12 days of high-energy burning with wheat and wood. However, the kiln operator's requirements were even stricter, requiring constant monitoring of the fire and timely removal of ash and replacement of wood. The purpose of constantly changing the fuel during kiln firing is to gradually raise the kiln temperature. Using straw to gradually evaporate the water mixed into the bricks, the temperature is around 110°C. Finally, a high-temperature fuel, such as pine branches, is used to melt the fusible particles in the clay and inject them into the pores of the bricks, densifying the bricks, shrinking their volume, and increasing their strength. This stage, called sintering, occurs at temperatures above 900°C. When the bricks are sintered at high temperature, the kiln workers seal the air vents on the kiln roof with mud to reduce the amount of air entering the kiln. A large amount of free carbon in the flame penetrates into the body through the pores, raising the temperature to around 1000°C until the reduction is completed.

[0022] Water seepage: Water seepage is a unique process in Chinese brickmaking. First, the fire pit and kiln roof are sealed with bricks. Then, water is released into the pool on the kiln roof. The water level in the pool must be maintained at a certain level, and the water seepage rate must also be maintained at a certain level. If it is too fast, the bricks will become brittle, while if it is too slow, the bricks will turn yellow or red.

[0023] Coming out of the kiln: Although water has been poured into the kiln to cool it down for four or five days, the temperature in the kiln is still very high, and the dust is filled, which is very choking.

[0024] Polishing: The gold bricks taken out of the kiln can only be regarded as semi-finished products. They must be sliced ​​and polished meticulously before they can become fine gold bricks.

[0025] The beneficial effects of the utility model are:

[0026] This product is easier to lay and can reduce the firing thickness of the brick body, allowing the kiln to fire more bricks at a time and increase production. The setting of the base plate structure can eliminate the step of leveling the ground and improve laying efficiency. The brick body is movable, which is convenient for later maintenance.

In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0033] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0034] In addition, in the description of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In this utility model, unless otherwise specified or limited, the terms "disposed," "socketed," "connected," "through," and "inserted" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0036] See Figure 1 and Figure 2 The retro imperial kiln gold brick shown includes a gold brick body 1 and a substrate structure 2 paved on the ground. The gold brick body 1 is laid on the substrate structure 2, and a buffer plate 3 is arranged between the gold brick body 1 and the substrate structure 2.

[0037] During laying, there is no need to level the ground. You only need to lay the substrate structure 2 on the ground. After leveling the substrate structure 2, you can proceed with subsequent laying. The buffer sheet 3 is placed between the substrate structure 2 and the brick body 1 to buffer the brick body 1 and reduce the breakage caused by hard collisions.

[0038] The thickness of the gold brick body 1 is significantly thinner than that of traditional gold bricks. The thickness of gold bricks in traditional technology is usually about 8.5 cm. However, the production capacity of the kiln is limited, and the thickness of the gold brick is large, which limits the production capacity of one firing. By reducing the thickness of the gold brick body 1, we can greatly increase the number of gold bricks fired at one time. In this embodiment, the thickness of the gold brick body 1 is 3 cm.

[0039] See Figure 2 and Figure 3 As shown, the substrate structure 2 includes a substrate 201, a support plate 202 is provided at the bottom of the substrate 201, and channels 203 for circulating mortar are formed between adjacent support plates 202. Stepped holes 204 are provided at the top of the substrate 201 near the four corners, and threaded pipes are cast and fixed at the small hole positions of the stepped holes 204. The threaded pipes have built-in threads, and leveling bolts 206 are fitted through the threaded pipes. The upper ends of the leveling bolts 206 are sunk into the large holes of the stepped holes 204, and the lower ends of the leveling bolts 206 are supported on the ground. The brick body 1 is supported by the substrate 201.

[0040] In the above technical solution, the leveling of the base plate 201 is completed by changing the position of the leveling bolts 206, so that the upper surface of the base plate 201 is a plane. After the base plate 201 is laid, self-leveling mortar is poured on the ground, and the self-leveling mortar is poured into the channel 203. The base plate 201 and the ground are poured together. After the mortar is dry, the brick body 1 is laid.

[0041] In traditional technology, it is necessary to level the ground first, then lay the cushion layer, then lay concrete on the bottom of the bricks, and then knock the surface of the bricks to level them. This operation method will result in relatively poor flatness of the bricks after laying, and will cause bumps and damage to the surface of the bricks, increasing the scrap rate.

[0042] Therefore, the paving method of the present technical solution is simpler to operate and has a lower scrap rate of gold bricks.

[0043] The base plate 201 is a prefabricated component, and the support plate 202 and the base plate 201 are integrated.

[0044] Preferably, a groove 207 is provided on the top of the substrate 201 , and the buffer sheet 3 is placed in the groove 207 . The thickness of the buffer sheet 3 after compression is greater than the depth of the groove 207 .

[0045] The groove 207 is used to position the buffer sheet 3 to prevent displacement of the buffer sheet 3 .

[0046] See Figure 2 As shown, the buffer sheet 3 is an elastic rubber sheet.

[0047] An anti-slip groove 31 is provided on the top of the buffer sheet 3 .

[0048] The provision of the anti-slip groove 31 can increase the stability of the brick body 1 after laying and reduce the displacement of the brick body 1.

[0049] A buffer hole 32 is injection-molded on the side of the buffer sheet 3 , and the buffer hole 32 passes through the buffer sheet 3 in a transverse direction.

[0050] The buffer hole 32 is provided to increase the deformation capacity of the buffer sheet 3 so that the buffer sheet 3 can be deformed better, absorb the force when the gold brick body 1 is stepped on, and play a protective role for the gold brick body 1.

[0051] A rubber strip 33 is implanted in the buffer hole 32 . The rubber strip 33 is solid. The elastic force of the rubber strip 33 is greater than the elastic force of the buffer sheet 3 . The rubber strip 33 is interference-fitted with the buffer hole 32 .

[0052] When thicker gold bricks are required to be laid, the elastic strips 33 can be provided to increase the anti-deformation capability of the buffer sheet 3 to prevent the buffer sheet 3 from being quickly flattened.

[0053] See Figure 2 As shown, a slurry feeding groove 221 is provided on the side of the substrate 201 .

[0054] The slurry filling groove 221 is provided to allow replenishment when the self-leveling material has difficulty flowing in the channel 203 , thereby ensuring that the self-leveling material can effectively fill each channel 203 .
