Description

Technical Field

[0001] This invention belongs to the field of ancient building restoration technology, specifically a device and method for restoring ancient building coffered ceilings. Background Technology

[0002] Ancient architecture is the crystallization of the wisdom of our ancestors. my country's ancient architecture possesses a profound historical heritage and is an invaluable material and spiritual asset. Furthermore, the unique construction style and structure of Chinese ancient architecture hold a very important place in the world. Ancient buildings are legacies of a long historical development, possessing extremely high historical, cultural, and scientific value. Throughout history, many ancient buildings have suffered damage or even destruction due to natural or human factors. Moreover, the rapid development of tourism in my country has brought enormous challenges to the protection and restoration of ancient buildings. Therefore, effective restoration and protection measures must be taken to ensure their continued existence.

[0003] A caisson ceiling, or caisson, is a dome-shaped ceiling found in ancient Chinese architecture. Rising high like an umbrella or canopy, or resembling an inverted bucket, suspended from the interior ceiling, it is the most vivid description of a caisson ceiling. Because ancient Chinese architecture was primarily wooden, the term "caisson ceiling" also carries the connotation of warding off fire. Therefore, caisson ceilings embody a profound cultural significance within traditional Chinese architecture. However, over time, the painted decorations and carvings on caisson ceilings gradually age and peel off, eventually causing them to lose their luster and necessitating restoration.

[0004] The restoration of caisson ceilings is mostly done manually, and specialized equipment is needed to ensure the smooth progress of the restoration work. Traditional caisson ceilings are not a single, monolithic structure, but rather assembled from several unit structures. Disassembling and repairing a caisson ceiling can easily damage its wooden structure and painted decorations, potentially causing further harm. To avoid these technical problems, it is indeed necessary to provide a restoration device and construction method for ancient architectural caisson ceilings to overcome the shortcomings of existing technologies.

[0048] A sliding plate 401 is installed at the top of the receiving trough plate 203. A sliding groove 402 is formed on the outer side of the sliding plate 401. A sliding engaging plate 403 is slidably engaged on the outer side of the sliding groove 402.

[0049] The working principle and usage process of this invention are as follows: First, the base 1 is moved to the bottom position of the caisson ceiling that needs repair. Then, the person stands on the top position of the positioning plate 301. Next, according to the height of the ancient building and the position of the caisson ceiling, the hydraulic lift 201 is raised and lowered to adjust the receiving trough plate 203 to a suitable height. Then, according to the height of the load-bearing beam of the caisson ceiling, the hydraulic strut 211 is raised and lowered at the top of the hydraulic support arm 210. At this time, the rotating rod 207 will rise inside the rotating groove 206, thereby supporting the multiple threaded support rods 214 to the bottom position of the corresponding load-bearing beam. Then, based on the distance between each load-bearing beam and the rotating rod 207, the hydraulic struts 211 are raised. Then, based on the actual deformation of the load-bearing beam, the threaded support rods 214 are rotated on the inner side of the support sleeve 213, so that the threaded support rods 214 are supported at the bottom of the load-bearing beam by the rubber pads 215. At this time, the entire caisson can be supported, preventing the caisson from falling during the repair. Moreover, the caisson does not need to be disassembled when repairing the ancient building caisson, ensuring the integrity of the caisson and further shortening the steps and time of the caisson repair, thereby improving the efficiency of the caisson repair.

[0050] Next, during the repair process, depending on the materials needed, the servo motor 306 is controlled to rotate, thereby driving the winding reel 307 to rotate and lower the thin cable 308 wound on the outside of the winding reel 307. At this time, the limiting frame 309 and the material box 310 will move towards the base 1. The workers below can place the materials or repair tools needed into the inside of the material box 310. Then, the repair personnel at the top can control the winding reel 307 to wind up the thin cable 308 again through the servo motor 306. This will drive the material box 310 and the inner materials to move upward. Then, when the limiting frame 309 moves to the bottom position of the positioning frame 303, the thin cable 308 is tightened to keep the limiting frame 309 in place. The bottom of the positioning frame 303 is pressed against the limiting frame 309, thereby fixing the material box 310 and preventing the material box 310 from shaking when the base 1 is moved, thus preventing the material from falling and being damaged. At this time, the material box 310 can be lifted and lowered to facilitate the transfer of materials, further improving the repair efficiency. The garbage generated during the repair process can be directly thrown into the top position of the receiving trough plate 203. This garbage will slide down with the receiving trough plate 203 to the recycling hole 311, and then fall into the garbage bag 315 at the bottom. After the repair work is completed, the adsorption iron sheet 314 can be removed and a new garbage bag 315 can be replaced, thereby preventing the garbage generated during the repair work from polluting the environment of the ancient building.

[0051] Finally, when performing paint repair, the graphic device can be embedded into the inner side of the placement slot 408 to fix the device. Then, the sliding snap plate 403 can be slid on the outside of the sliding plate 401 and slid to a suitable viewing position. Then, the placement plate 407 is rotated according to the rotating column 405 to adjust to a suitable viewing angle. Then, the height setting screw 410 is loosened to adjust the height of the lifting plate 404. People can then perform color repair while making a comparison, which can prevent the use of paint incorrectly, thereby improving the quality of the coffered ceiling repair and further improving the repair efficiency.

[0052] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
