Description

Technical Field

[0001] This utility model relates to the field of antique building technology, and in particular to a prefabricated metal dougong caisson ceiling. Background Technology

[0002] In antique-style architecture, caisson ceilings are not only a decoration, but also a cultural symbol and a means of inheriting craftsmanship. Among them, the octagonal caisson ceiling is the most classic, highest-level, and most representative type of caisson ceiling.

[0003] Due to their unique design, caisson ceilings are difficult to standardize in production. Because of the characteristics of ancient mortise and tenon joints, caisson ceilings have traditionally been installed using a reverse-overlapping method, i.e., installed in the order of circular ceiling → octagonal ceiling → square ceiling, which requires precise handling of the splicing angles and makes installation difficult. Meanwhile, while the widespread use of high-performance metal materials in the field of antique-style architectural decoration has reduced the weight of caisson ceilings, it has brought a significant problem: the treatment of welds. Welds not only affect aesthetics but also pose a risk of metal deformation during the welding process. Therefore, this utility model proposes a prefabricated metal octagonal caisson ceiling to solve the above problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a prefabricated metal octagonal caisson ceiling. By configuring each of the eight prefabricated well blocks of the octagonal well body as a first connecting unit, a first horizontal unit, a second connecting unit, a first continuous curved surface unit, a third connecting unit, a second horizontal unit, a fourth connecting unit, a second continuous curved surface unit, and a fifth connecting unit, the prefabricated octagonal well body can be assembled using a positive stacking method, which can greatly reduce the installation difficulty.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted: An assembled metal octagonal caisson ceiling includes a square well body, an octagonal well body, a circular well, and corner ornaments. The octagonal well body is located inside the square well body, and the circular well is located on the top of the octagonal well body. Corner ornaments are located at the four corners between the square well body and the octagonal well body. The square well body is composed of four sets of square well rods, and the octagonal well body is composed of eight assembled well blocks. Each of the eight assembled well blocks is composed of a first connecting unit, a first horizontal unit, a second connecting unit, a first continuous curved surface unit, a third connecting unit, a second horizontal unit, a fourth connecting unit, a second continuous curved surface unit, and a fifth connecting unit. A first horizontal unit is located between the first and second connecting units, a first continuous curved surface unit is located between the second and third connecting units, a second horizontal unit is located between the third and fourth connecting units, and a second continuous curved surface unit is located between the fourth and fifth connecting units.

[0006] A further improvement is that the vertical joints between adjacent prefabricated well blocks are welded and fixed on the back, and the backs of the first connecting unit, the first horizontal unit, the second connecting unit, the first continuous curved surface unit, the third connecting unit, the second horizontal unit, the fourth connecting unit, the second continuous curved surface unit, and the fifth connecting unit are sequentially connected by the first bolt.

[0007] A further improvement is that the lower end of the first connecting unit of the four sets of assembled well blocks at the positions adapted to the four sets of square well rods is connected to the square well rod by a second bolt.

[0008] A further improvement is that the lower end of the first connecting unit of the four sets of prefabricated well blocks corresponding to the four sets of cicada positions is connected to the cicada by a third bolt.

[0009] A further improvement is that the four sets of cicadas and the four sets of square well rods are connected by a fourth bolt.

[0010] A further improvement is made by welding and fixing the vertical joints between the four sets of square well rods.

[0011] A further improvement is that: brackets are provided on the back of the first connecting unit, between the back of the second connecting unit, and between the back of the third connecting unit and the back of the fourth connecting unit; and bow-shaped ribs are provided on the back of the first continuous curved surface unit and the second continuous curved surface unit.

[0012] The beneficial effects of this utility model are as follows: This utility model sets the eight prefabricated well blocks of the octagonal well body to be composed of a first connecting unit, a first horizontal unit, a second connecting unit, a first continuous curved surface unit, a third connecting unit, a second horizontal unit, a fourth connecting unit, a second continuous curved surface unit, and a fifth connecting unit. The back sides of adjacent units are connected by a first bolt, so that the octagonal well body can form a prefabricated structure. The prefabricated octagonal well body can be installed by positive stacking method during assembly, which can greatly reduce the installation difficulty. In this utility model, the nine individual units of the prefabricated well block are welded and fixed only at the vertical joints. The welds produced by the vertical welding can be hidden behind the arched ribs and the shape of the brackets, which reduces the process requirements for the welds during installation and further reduces the installation difficulty of the metal bracket caisson.

[0017] When installing the prefabricated metal octagonal caisson ceiling of this utility model using the positive stacking method, firstly, four sets of square well rods 101 are installed. The four sets of square well rods 101 are welded at the vertical joints to form a square well frame structure. Then, the first connecting units 5 of four sets of prefabricated well blocks 201 are installed sequentially, with the first connecting units 5 connected at the center position inside the square well rods 101. Next, the first connecting units 5 of the remaining four sets of prefabricated well blocks 201 are installed. The eight sets of first connecting units 5 are welded together at the vertical joints, so that the eight sets of first connecting units 5 form an octagon. Then, the assembly is completed layer by layer. After all eight prefabricated well blocks 201 are assembled, the remaining eight individual units (i.e., the first horizontal unit 6, the second connecting unit 7, the first continuous curved surface unit 8, the third connecting unit 9, the second horizontal unit 10, the fourth connecting unit 11, the second continuous curved surface unit 12, and the fifth connecting unit 13) are assembled, four sets of corner cicadas 4 are installed between the square well body 1 and the octagonal well body 2 (i.e., between the square well body 1 and the four sets of first connecting units 5), and then the round well 3 is installed. Finally, the joints between adjacent prefabricated well blocks 201 are welded and fixed on the back.

[0018] The vertical joints between adjacent prefabricated well blocks 201 are welded and fixed on the back. The backs of the first connecting unit 5, the first horizontal unit 6, the second connecting unit 7, the first continuous curved surface unit 8, the third connecting unit 9, the second horizontal unit 10, the fourth connecting unit 11, the second continuous curved surface unit 12, and the fifth connecting unit 13 are sequentially connected by the first bolt. That is, when splicing the first connecting unit with one end of the first horizontal unit 6, when connecting the first horizontal unit 6 with one end of the second connecting unit 7, when connecting the second connecting unit 7 with one end of the first continuous curved surface unit 8, when connecting the first continuous curved surface unit 8 with one end of the third connecting unit 9, when connecting the third connecting unit 9 with one end of the second horizontal unit 10, when connecting the second horizontal unit 10 and one end of the fourth connecting unit 11, and when connecting the second continuous curved surface unit 12 and one end of the fifth connecting unit 13, adjacent units are connected on the back by the first bolt.

[0019] The lower end of the first connecting unit 5 of the four sets of assembled well blocks 201 at the positions adapted to the four sets of square well rods 101 is connected to the square well rod 101 by a second bolt.

[0020] The lower end of the first connecting unit 5 of the four sets of assembled well blocks 201 corresponding to the positions of the four sets of cicadas 4 is connected to the cicada 4 by a third bolt.

[0021] The four sets of cicada 4 and the four sets of square well rods 101 are connected by a fourth bolt.

[0022] The vertical joints of the four sets of square well rods 101 are welded and fixed together.

[0023] A bracket 14 is provided between the back of the first connecting unit 5 and the back of the second connecting unit 7, as well as between the back of the third connecting unit 9 and the back of the fourth connecting unit 11. An arched rib 15 is provided on the back of both the first continuous curved surface unit 8 and the second continuous curved surface unit 12. The brackets 14 and arched ribs 15 are both located at the vertical joints between adjacent prefabricated well blocks 201. The brackets 14 and arched ribs 15 not only complete the structure of the prefabricated metal caisson ceiling, but also conceal and cover the weld seams.

[0024] This utility model sets the eight prefabricated well blocks 201 of the octagonal well body 2 to be composed of a first connecting unit 5, a first horizontal unit 6, a second connecting unit 7, a first continuous curved surface unit 8, a third connecting unit 9, a second horizontal unit 10, a fourth connecting unit 11, a second continuous curved surface unit 12, and a fifth connecting unit 13. The back sides of adjacent units are connected by a first bolt, so that the octagonal well body 2 can form a prefabricated structure. The prefabricated octagonal well body 2 can be installed by a positive stacking method, which can greatly reduce the installation difficulty. In this utility model, the nine units of the prefabricated well block 201 are welded and fixed only at the vertical joints. The welds produced by the vertical welding can be hidden behind the arched ribs and the shape of the brackets, which reduces the process requirements of the welds during installation and further reduces the installation difficulty of the metal octagonal caisson.
