Description

Technical Field

[0001] The invention relates to the technical field of mineral wool board ceiling systems, and in particular to a concealed keel hook used in a visible and concealed frame ceiling system. Background Art

[0002] The visible and concealed frame ceiling system is a common ceiling method used in mineral wool board ceiling systems. The visible and concealed frame ceiling system can combine the advantages of the visible frame ceiling system and the concealed frame ceiling system, and is widely used.

[0003] In the existing exposed and concealed ceiling system, the exposed keel often adopts T-shaped painted keel, and the concealed keel often adopts H-shaped light steel keel with built-in hooks, such as Figure 6 As shown, the H-shaped light steel keel is hung on the exposed keel through hooks to support the mineral wool board. However, during the construction process, it was found that due to the adjustment and deviation of the installation size, the hidden keel needed to be cut. Especially during the corridor construction process, the corridor width is often inconsistent, the size deviation is large, and many keels need to be corrected. After cutting, the hooks of the hidden keel will be cut off, affecting the use. The hooks need to be cut manually on site, which seriously affects the efficiency of construction. In addition, the quality of the hooks cut on site is low, which seriously affects the forming effect of the construction. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention designs a hidden keel hook used in a visible and hidden frame ceiling system. The hidden keel hook is fixedly installed on the end of an H-shaped light steel keel with the hook cut off, and is used to hang the H-shaped light steel keel on the visible keel to support the mineral wool board. The hidden keel hook includes: a hidden keel connector, fixedly installed on the end of the H-shaped light steel keel with the hook cut off; and a visible keel connector, fixedly connected to the hidden keel connector, and used to hang on the visible keel.

[0005] Preferably, the concealed keel connector includes: a first connecting plate; a second connecting plate, which is arranged on the first connecting plate and is fixedly installed in cooperation with the first connecting plate on the end of the H-shaped light steel keel with the hook cut off.

[0006] Preferably, the concealed keel connector is made by stamping and cutting of steel plates.

[0007] Preferably, the visible keel connector includes: a plurality of vertical ribs that are evenly arranged; and a connecting plate that is used to connect adjacent vertical ribs and is fixedly connected to the hidden keel connector.

[0008] Preferably, the number of vertical ribs is 2n, where n is a positive integer, and they are symmetrically distributed on both sides of the hidden keel connector.

[0009] Preferably, the number of vertical ribs is 2n+1, where n is a positive integer, one of the vertical ribs is located at the extension surface of the hidden keel connector, and the 2n vertical ribs are symmetrically distributed on both sides of the hidden keel connector.

[0010] Preferably, the exposed keel connector is made by stamping and bending a steel plate.

[0011] Preferably, the visible keel connector is provided with a mounting groove on a side close to the concealed keel connector, and the visible keel connector is hung on the visible keel through the mounting groove.

[0012] Preferably, the mounting groove includes a first groove surface and a second groove surface; the number of the first groove surfaces is at least two, and all of them are flush and fit against the side surface of the exposed keel; the number of the second groove surfaces is at least two, and all of them are flush and fit against the top surface of the exposed keel.

[0013] Preferably, the concealed keel connector and the visible keel connector are an integrated structure, and are manufactured by integrally stamping, bending and cutting of steel plates.

[0014] Compared with the closest prior art, the beneficial effects of the present invention are:

[0015] 1. After the hooks are cut off from the H-shaped light steel keels, the present invention uses hidden keel hooks to hang the H-shaped light steel keels on the visible keels, which is convenient to install and improves installation efficiency. In addition, for special specifications or more specifications and sizes of visible and hidden frame ceilings, the hidden keels can be installed by using common H-shaped light steel keels. The ordinary H-shaped light steel keels are cut and installed by hidden keel hooks, which reduces the trouble of too many and complicated customization types, saves manpower and material resources, and improves construction efficiency.

[0016] 2. The number of the vertical ribs of the present invention can be an odd number or an even number. When it is an odd number, one of the vertical ribs is located at the extension surface of the hidden keel connector, and the remaining vertical ribs are symmetrically distributed on both sides of the hidden keel connector. When it is an even number, the vertical ribs are symmetrically distributed on both sides of the hidden keel connector. The number of vertical ribs is set to multiple, so that multiple vertical ribs can contact the surface of the exposed keel at the same time, support each other, and maintain stability. During the installation process, the H-shaped light steel keel can always remain perpendicular to the exposed keel, which can improve the stability of the keel compared to a single hook.

[0017] 3. The first groove surface and the second groove surface of the present invention are fitted to the side surface and the top surface of the exposed keel, and the number of the first groove surface and the second groove surface is at least two. In this way, when the exposed keel connector is hooked on the exposed keel, multiple first groove surfaces and multiple second groove surfaces can contact the surface of the exposed keel at the same time, support each other, and maintain stability. During the installation process, the H-shaped light steel keel 1 can always remain vertical to the exposed keel, and the H-shaped light steel keel can slide on the exposed keel.
