Description

Technical Field

[0001] The utility model belongs to the technical field of ceiling decoration, and particularly relates to a connecting structure of ceiling keels. Background Art

[0002] When connecting two existing mutually perpendicular ceiling keels, usually a flange is provided at the end of one keel, and then the flange at the end of the keel is locked to the side wall of the other mutually perpendicular keel through a bolt assembly, so as to realize the connection of the two criss-cross keels; the whole process is inconvenient to install and time-consuming.

[0003] The same-day application of the present utility model records a quick-install prefabricated ceiling module. A keel connector is recorded in the same-day application. Part of the technical solutions of the present utility model are recorded in the keel connector but not claimed. Therefore, the present utility model particularly claims a connecting structure of a ceiling keel. Summary of the Utility Model

[0009] Optionally, the first clamping piece body is in an L shape.

[0010] The beneficial effects of the present utility model are as follows:

[0011] The utility model provides a connection structure for ceiling keels. The ceiling keel includes a first keel and a second keel that are perpendicular to each other in a horizontal plane. The connection structure includes a profiled steel matrix, a first clamping piece body, and a second clamping piece body. One end of the profiled steel matrix is clamped inside the second keel. At the top of the other end of the profiled steel matrix, there is a first clamping piece body, and at the bottom, there is a second clamping piece body. The second keel is located between the first clamping piece body and the second clamping piece body. When in use, by clamping one end of the profiled steel matrix inside the second keel and then clamping the first keel directly between the first clamping piece body and the second clamping piece body, the connection between the perpendicular ceiling keels can be achieved, and the installation and disassembly are both faster and more efficient. At the same time, in the technology of prefabricated ceiling modules, the ceiling decorative board is usually integrally arranged with the ceiling keel. Therefore, the utility model can also be used for the rapid connection of two prefabricated ceiling modules. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In this embodiment, as Figures 1 to 6A connecting structure for a ceiling keel is shown. The ceiling keel includes a first keel 4 and a second keel 5 that are perpendicular to each other in the horizontal plane. The connecting structure includes a profiled steel matrix 1, a first clamping piece 2, and a second clamping piece 3. One end of the profiled steel matrix 1 is clamped inside the second keel 5. At the top of the other end of the profiled steel matrix 1, a first clamping piece 2 is provided, and at the bottom, a second clamping piece 3 is provided. The second keel 5 is located between the first clamping piece 2 and the second clamping piece 3. When in use, by clamping one end of the profiled steel matrix 1 inside the second keel 5, and then clamping the first keel 4 directly between the first clamping piece 2 and the second clamping piece 3, the connection between the perpendicular ceiling keels can be achieved.

[0020] At the same time, in the same-day application of the present utility model, a prefabricated ceiling module is described. During the factory production stage, the ceiling keel is nailed to the ceiling decorative board through screws and connected together to form a ceiling module. However, generally, the screws nail the middle part of the ceiling keel, and there are still gaps in the edge area of the ceiling keel. Therefore, the second clamping piece 3 can still be clamped in the gap between the ceiling keel and the ceiling decorative board to achieve the connection between the keels on two different ceiling decorative boards. Therefore, the present utility model can also be used for the rapid connection of two prefabricated ceiling modules.

[0021] In this embodiment, the length of the first clamping piece 2 should be greater than the width of the first keel 4, and the length of the second clamping piece 3 should be less than half of the width of the first keel 4.

[0022] In this embodiment, as Figure 2 shown, an arc-shaped elastic piece 31 is provided between the second clamping piece 3 and the profiled steel matrix 1. The second clamping piece 3 is parallel to the bottom wall of the profiled steel matrix 1. One end of the second clamping piece 3 close to the profiled steel matrix 1 has an inclined section 32, and the arc-shaped elastic piece 31 is connected to the inclined section 32. The arc-shaped elastic piece 31 enables the first clamping piece 2 and the second clamping piece 3 to clamp the first keel 4 more tightly.

[0023] In this embodiment, the first clamping piece 2 is L-shaped. The L shape enables the second clamping piece 2 to bear more longitudinal stress, so that the second clamping piece 2 can meet the load-bearing requirements for the installation of the ceiling decorative board.
