Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a load-bearing keel. Background Technology

[0002] Ceiling joists are structural components that serve as installation nodes for ceilings, acting as a connecting link between the upper and lower parts of a suspended ceiling. During interior decoration, joists are first installed on the walls and ceiling, and then the suspended ceiling is installed using these joist frameworks.

[0003] As shown in existing technologies such as CN218643657U and CN211774993U, the existing ceiling keel generally consists of four main parts: main keel, secondary keel, mounting bracket, and connector. The main keel and secondary keel are perpendicular to each other and connected by connector to form a keel frame, while the mounting bracket is used to connect the keel frame to the ceiling. The disadvantages of this structure are: 1. It mainly relies on the mounting bracket for load-bearing, and the location of the connector is prone to sagging, resulting in limited load-bearing capacity and a need to improve load-bearing performance; 2. It requires two structures, the mounting bracket and the connector, which is costly and the installation process is complicated and cumbersome. Utility Model Content

[0052] In this embodiment, the second ceiling mechanism 5 includes a second suspension rod 51, a second expansion bolt 52, a first bracket 53, a second bracket 54, a sixth nut 55, and a seventh nut 56.

[0056] Example 2

[0057] like Figure 11-13 As shown, this utility model provides another type of load-bearing keel.

[0058] The structure of the load-bearing keel is basically the same as that of Embodiment 1, except that: the secondary keel 2 in this embodiment includes a first secondary keel 2a and a second secondary keel 2b. The first secondary keel 2a is perpendicular to the main keel 1 and the intersection is connected by a connector 3. The second secondary keel 2b is perpendicular to the first secondary keel 2a and the intersection is connected by a connector 3.

[0059] The connection between the first secondary keel 2a, the main keel 1, and the connector 3 refers to the connection structure and method between the secondary keel 2, the main keel 1, and the connector 3 in the above embodiment 1.

[0062] The load-bearing keel of Example 2 is suitable for installation on square ceilings with smaller dimensions (e.g., 600mm*600mm).

[0063] As described above, the load-bearing keel of this utility model has at least the following advantages compared to the prior art:

[0064] 1. This utility model provides a load-bearing keel with a brand-new structure. The load-bearing keel directly connects the connector 3 to the ceiling or other top mounting surface. That is, the connector 3 serves both as a connector and as a load-bearing component. It not only has good load-bearing performance, but also effectively reduces the number of accessories such as mounting brackets, resulting in low cost and high assembly efficiency.

[0065] 2. The connector 3 of this utility model is not only suspended by the vertically arranged first ceiling mechanism 4, but also by the inclined second suspension rod 51 mechanism. This makes the connector 3 of this utility model bear force evenly and further improves the load-bearing performance.

[0066] 3. A spiral adjustment mechanism 44 is provided between the vertically set first ceiling mechanism 4 and the connecting part 3. The height can be adjusted through the spiral adjustment mechanism 44. It is highly applicable, easy to adjust, and meets the installation needs of complex scenarios.
