Description

A T-shaped keel cross fastener

technical field

The utility model belongs to the field of architectural decoration suspended ceilings, and relates to a fastener for a T-shaped keel, specifically a T-shaped keel cross fastener used for connecting surface-mounted keels of a suspended ceiling.

Background technique

The installation method of the suspended ceiling is divided into the installation method of the keel installation method and the installation method of the concealed keel installation. The dark keel installation is that there is a tongue and groove on the edge of the veneer, and the skeleton is not exposed after embedding. Ming keel installation means that the vertical and horizontal T-shaped keel skeletons are exposed, and the decorative panels only need to be placed on the two wings of the T-shaped. For the ceiling frame assembled by T-shaped main and auxiliary keels, there are generally the following connection methods: First, there are round holes and square holes on the side of the T-shaped main keel, the round holes are used for suspension, and the square holes are used for the secondary keel The male head is inserted directly. Second, for the T-shaped keel without holes, you can cut out the connecting feet at the end of the secondary keel, and after bending 90°, use self-tapping screws to make a T-shaped connection with the main keel, or punch a rectangular hole on the main keel. Insert the connecting feet of the secondary keel into the rectangular holes. Using angular aluminum alloy blocks again, the primary and secondary keels are fixed and connected with self-tapping screws.

The above T-shaped main and auxiliary keels are relatively common connection methods. On the one hand, the strength of the skeleton composed of these connection methods is not very high, and it is easy to cause looseness after a long time. On the other hand, bending parts are required. When installing and disassembling It is easy to cause breakage and is not easy to install and disassemble.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide a T-shaped keel cross fastener, so that the T-shaped main and auxiliary keels are not only connected very tightly, but also more convenient for installation and disassembly.

In order to achieve the above purpose, the technical solution of the present invention is: a T-shaped keel cross fastener for connecting T-shaped main and auxiliary keels, which is characterized in that it includes a cross fastening metal sheet, a screw and a nut, and the cross metal Each side of the fastening sheet is a U-shaped groove structure. The size of the U-shaped groove structure matches the T-shaped main and auxiliary keels. There are bolt holes on each side. The cross fastening metal sheet is connected with the screw through the screw. The nut is connected and fixed with the T-shaped main and auxiliary keels.

The T-shaped keel cross fastener described above is characterized in that an angular connecting piece is arranged between two adjacent sides of the cross fastening metal sheet.

The T-shaped keel cross fastener is characterized in that there are two nuts, and after the screw rod passes through the bolt hole, its two ends are fixed by nuts.

The above-mentioned T-shaped keel cross fastener is characterized in that a gasket is arranged between the nut and the cross fastening metal sheet.

A T-shaped keel cross fastener of the utility model, when in use, the cross fastening metal sheet is fixed on the upper end of the T-shaped main and auxiliary keel, and one of the nuts is inserted along the groove of the T main and auxiliary keel, and is connected with the bolt hole. Alignment, screw the screw into the nut, and lock the other end with the nut, that is, to achieve a stable connection of the T-shaped main and auxiliary keels. When disassembling, follow the above process in reverse. By adopting the above scheme, the utility model can stably connect the T-shaped main and auxiliary keels. It has fewer components, excellent mechanical properties, and convenient installation. It can realize factory production, reduce the workload on the construction site, and simplify the on-site construction process. Adapt to the development trend of factory production and on-site installation of architectural decoration ceiling systems.
