Technical Field

[0002] With rapid urbanization, the construction industry has ushered in unprecedented development opportunities, with a large number of residential and commercial buildings emerging. To meet the demands of rapid construction, traditional building decoration methods have gradually revealed their inefficiency. Prefabricated keel systems, with their rapid assembly capabilities, can effectively shorten the building decoration cycle and meet the needs of large-scale construction. From the perspective of the entire building lifecycle, prefabricated keels have the advantages of reusability and ease of dismantling and modification, aligning with the concept of sustainable development. During the building's use, if space needs to be modified or adjusted, prefabricated keels can be easily disassembled and reassembled, reducing damage to the building structure, minimizing construction waste, and promoting resource recycling.
[0003] A search revealed Chinese Patent Publication No. CN222375778U, which discloses a modular building ceiling keel system, comprising several covering keels and load-bearing keels. The load-bearing keels are mounted on the covering keels, and the covering keels have internal mounting positioning grooves. The connection between the load-bearing keels and the covering keels is detachable via a mounting positioning structure. Adjustable hanger assemblies are installed at both ends of the top of the load-bearing keels. Horizontal cross braces are provided between the connected covering keels, and both ends of the horizontal cross braces are provided with horizontal positioning structures connected to the outer wall of the covering keels. The advantages of this invention are: simple structure, convenient installation, and the ability to adjust the height of the load-bearing keels and covering keels as needed, thus adapting to different ceiling heights and improving the convenience and efficiency of assembling and connecting the building ceiling keels. However, this invention does not consider the possibility that if the keels cannot be adequately supported, a corner of one keel may sag under pressure, posing a threat to the safety of workers.

Then, rotate the rotating plate to make it rotate around the rotating axis and make the fixed plate and the baffle fit tightly together. When the unit keel is under pressure, the pressure can be converted into the thrust between the baffle and the fixed plate, which improves the structural stability and prevents the unit keel from falling when under pressure, thereby improving the safety of the equipment.
[0032] 2. In this utility model, during disassembly, the screw is rotated to loosen it from the second unit keel, and the vertical support plate and the second unit keel are no longer fixed and can be disassembled. Then, the fixing block is pressed down, and the sliding column will slide into the inside of the first unit keel, pushing the triangular block into the inside of the connecting plate, compressing the spring column, thereby allowing the connecting plate to be pulled out from the first hollow groove, realizing the disassembly of the equipment, simplifying the disassembly steps, allowing the user to operate with one hand, and improving the convenience of the equipment.

[0049] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The disassembly assembly 303 includes two sliding columns 3031. The outer walls of the two sliding columns 3031 are slidably connected to the left and right sides of the inner wall of the unit keel 1. A fixing block 3032 is fixedly connected to the two sliding columns 3031 at opposite ends. The engaging assembly 304 includes a spring column 3041. The outer walls of the spring column 3041 are fixedly connected to the left and right sides of the inner wall of the connecting plate 201. A triangular block 3042 is fixedly connected to the two spring columns 3041 at opposite ends.
[0050] Specifically, the sliding column 3031 is slidably connected to the unit keel 1, which not only ensures the stability and durability of the component, but also provides great convenience during operation.

Then pull the rotating plate 2052, so that the rotating plate 2052 rotates around the outer wall of the rotating shaft 2051, and the fixing plate 2062 and the baffle 2061 are attached together. When the unit keel 1 receives pressure, it can be converted into thrust between the baffle 2061 and the fixing plate 2062, which improves the structural stability and prevents the unit keel 1 from falling when it receives pressure, thereby improving the safety of the equipment.
[0052] During disassembly, screw 302 is turned out of the inner wall of the vertical support plate 202 from the second unit keel 301. The vertical support plate 202 and the second unit keel 301 are then unsecured and can be disassembled. Then, the fixing blocks 3032 on both sides are pressed, which pushes the sliding column 3031, causing the sliding column 3031 to slide into the interior of the first unit keel 1. This pushes the triangular block 3042 into the interior of the connecting plate 201 and squeezes the spring column 3041, allowing the connecting plate 201 to be pulled out from the hollow groove 203. This simplifies the disassembly process, allows users to operate with one hand, and improves the convenience of the equipment.
