Description

Technical Field

[0001] This utility model relates to a ceiling keel, and more particularly to a building decoration ceiling keel. Background Technology

[0002] A suspended ceiling refers to the decorative structure at the top of a room, typically installed above the ceiling. Suspended ceilings can come in various designs and materials, such as gypsum board ceilings, aluminum alloy ceilings, and PVC ceilings. Installation requires pre-installing a ceiling joist (or framing) within the room to allow for the installation of the ceiling panels. Ceiling joists are primarily made of light steel or wood. Light steel joists are widely used in decoration work due to their good toughness, high hardness, and fire resistance. Installation methods for light steel joists mainly include U-shaped support clip-on light steel joists, clip-on light steel joists, and suspended light steel joists.

[0003] When installing clip-on ceiling joists, expansion bolts are usually first installed on the floor slab, followed by the installation of hangers and main joists. The main joists generally have evenly distributed slots on both sides, and the secondary joists have limiting parts at both ends that correspond to the slots. The connection between the secondary joists and the main joists is achieved by the cooperation of the limiting parts and the slots. Finally, the connection is fixed by fasteners. However, the installation spacing of the secondary joists is affected by the spacing of the main joist slots, resulting in poor applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a ceiling joist for building decoration. It has the advantages of convenient installation and good applicability.

[0005] The technical solution of this utility model is as follows: A ceiling keel for building decoration includes a suspension rod assembly. A main keel is provided on the lower side of the suspension rod assembly. An installation component that can move relative to the main keel is provided on the outside of the main keel. A secondary keel is provided on the lower side of the installation component. The installation component includes an upper installation component set on the main keel and a lower installation component set on the secondary keel that can be lifted relative to the upper installation component. An installation groove is provided in the middle of both ends of the upper installation component. Positioning holes are provided on both sides of the installation groove. A slot corresponding to the secondary keel is provided in the lower installation component. A support piece that can be detached relative to the slot is provided at the top of the slot. Positioning protrusions corresponding to the positioning holes are provided at both ends of the support piece.

[0006] In the aforementioned type of ceiling keel for building decoration, the lower mounting component includes a connecting part that fits against the upper side of the secondary keel, and the lower sides of both ends of the connecting part are provided with inwardly bent and obliquely upward retaining edges.

[0007] In the aforementioned type of ceiling keel for building decoration, the upper mounting component includes a protrusion corresponding to the main keel, and horizontal portions are provided on both sides of the protrusion, with mounting grooves located in the horizontal portions.

[0008] In the aforementioned type of ceiling keel for building decoration, a reinforcing rib is provided between the protruding part and the horizontal part.

[0009] In the aforementioned type of ceiling keel for building decoration, the upper end of the support plate is provided with a limiting strip corresponding to the lower mounting component.

[0010] Compared with the prior art, this utility model has an upper mounting component pre-installed on the main keel and a lower mounting component pre-installed on the secondary keel. During installation, the upper end of the lower mounting component passes through the mounting groove, and then the support plate is connected to the upper end of the groove. The positioning protrusions at both ends of the support plate are aligned with the positioning holes, so that the support plate can support the lower mounting component, making the installation convenient and quick.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example. A type of ceiling joist for architectural decoration, comprising as follows: Figure 1-3 As shown, the device includes a hanger assembly 1. The hanger assembly 1 has a main keel 2 on its lower side. The main keel 2 has a mounting component that can move relative to the main keel 2. The mounting component has a secondary keel 16 on its lower side. The mounting component includes an upper mounting component 3 set on the main keel 2 and a lower mounting component 5 set on the secondary keel 16 that can be raised relative to the upper mounting component 3. The upper mounting component 3 has a mounting groove 4 at the middle of both ends. The mounting groove 4 has positioning holes 6 on both sides. The lower mounting component 5 has a slot 7 corresponding to the secondary keel 16. The top of the slot 7 has a support piece 8 that can be detached relative to the slot 7. The support piece 8 has positioning protrusions 9 at both ends that correspond to the positioning holes 6.

[0017] The lower mounting component 5 includes a connecting part 10 that fits against the upper side of the secondary keel 16, and the lower sides of both ends of the connecting part 10 are provided with retaining edges 11 that bend inward and obliquely upward.

[0018] The upper mounting component 3 includes a protrusion 12 corresponding to the main keel 2, and horizontal portions 13 are provided on both sides of the protrusion 12, with mounting grooves 4 provided in the horizontal portions 13.

[0019] A reinforcing rib 14 is provided between the protrusion 12 and the horizontal part 13.

[0020] The upper end of the support piece 8 is provided with a limiting strip 15 corresponding to the lower mounting piece 5.

[0021] The principle of this utility model: Before installation on the wall, the upper mounting part 3 is installed according to the required spacing of the secondary keel 16. The upper mounting part 3 is set on the upper end of the main keel 2 through the protrusion 12 and is fixedly connected by fasteners. Then, the lower mounting part 5 is fixed to the outside of the secondary keel 16. During installation, the main keel 2 is installed through the hanger assembly 1. Then, the secondary keel 16 is raised so that the lower mounting part 5 installed on the upper end of the secondary keel 16 passes through the mounting groove 4 of the upper mounting part 3. Then, the support piece 8 passes through the slot 7 and the limiting strip 15 engages with the lower mounting part 5 to achieve positioning. Then, the secondary keel 16 is slowly lowered so that the positioning protrusion 9 on the support piece 8 engages with the positioning hole 6. The installation is convenient and reliable, and has good applicability. Furthermore, the main keel and secondary keel can be further locked by fasteners such as bolts and nuts.
