Description

Technical Field

[0001] This utility model relates to the technical field of keel installation, and more specifically, to a ceiling keel installation component. Background Technology

[0002] Interior ceiling refers to the decoration of the ceiling in a room. Most decorative interior ceilings use a light steel keel as a frame, and then gypsum board is suspended from the light steel frame. The light steel keel is a frame made by cold-bending continuous hot-dip galvanized steel strip. Figure 6 As shown, this is a commonly used light steel keel structure. Light steel keel ceilings are lightweight, high-strength, dustproof, soundproof, and heat-insulating. In decoration projects, light steel keel ceilings are widely used in various industrial and civil buildings.

[0003] However, in the actual installation process, the existing light steel keel requires a lot of steel and fasteners, and there are also many holes to be drilled in the floor slab, which causes a certain degree of damage to the concrete surface of the floor slab and increases the load on the building floor slab, thus affecting the quality and service life of the building floor slab. In addition, the installation operation is complicated and the construction time is long, resulting in high labor costs, which is an area that needs to be improved.

[0004] To address the aforementioned issues, patent "CN214423737U" discloses "an adjustable ceiling keel installation assembly." This technology uses keel hangers to suspend the light steel keel. However, when the lower end of the light steel keel is directly connected to the gypsum board using self-tapping screws, the support plate at the lower end of the keel hanger creates a gap between the light steel keel and the gypsum board, thus affecting the connection strength of the self-tapping screws.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0029] like Figure 1-5As shown, this utility model discloses a ceiling keel installation component, including a first connector 100. The first connector 100 is connected to a second connector 200 via a pin 110. The first connector 100 includes a square support portion 120. Elongated support blocks 121 and 122 are symmetrically arranged on the left and right sides of the upper and lower bottom surfaces of the support portion 120, respectively. A square pin connection portion 130 is provided in the center of the upper bottom surface of the support portion 120. The connecting part 130 is provided with a pin assembly. The second connecting member 200 includes a rod connecting part 210. The rod connecting part 210 has pin holes 211 symmetrically arranged on both sides to match the pin 110. The lower end of the rod connecting part 210 is provided with a U-shaped clamping part 220. The left and right sides of the lower end of the clamping part 220 are symmetrically provided with clamping grooves 221. The middle part of the second connecting member 200 is provided with an installation slot 230 to match the pin connecting part 130. Example 1

[0030] In this application, the upper support surface of support block 121 and the lower support surface of support block 22 are both arc-shaped surfaces. The upper support surface of support block 121 is adapted to the groove 310 at the upper end of the keel 300. The arc-shaped surface design facilitates the insertion of the first connector 100 into the U-shaped groove of the keel 300, and also facilitates the relative movement of the first connector 100 and the keel 300. The relative movement is specifically as follows: first, the two first connectors 100 are inserted into the left and right side openings of the keel, and then, according to the second connector 20 on the hanger... Adjust the positions of the two first connectors 100 by sliding them at position 0. After adjustment, insert the first connector 100 into the mounting slot 230 of the second connector 200. Initially, insert only a portion to check if the keel 300 needs to be adjusted. If so, move the keel 300 left or right. Once the keel 300 is in the appropriate position, simply insert the first connector 100 all the way up so that the pin 110 is inserted into the pin hole 211, thus completing the clamping and hoisting of the keel 300 by the first connector 100 and the second connector 200.

[0031] The pin assembly in this application includes a vertical partition 131, a guide rod 132, a pin support plate 133, and a spring 134. The pin assembly allows the pin 110 to be quickly inserted into the pin hole 211. A mounting slot 230, adapted to the pin connection portion 130, is provided in the middle of the second connector 200. The depth of the mounting slot 230 is equal to the height of the pin connection portion 130. The pin connection portion 130 can be inserted through the mounting slot 230, and the pin 110 extends out of the guide hole. The upper end of the connector is a downward-sloping structure. When the pin connection part 130 is inserted upward into the position of the pin 110, guided by the slope structure, and under the action of the pin support plate 133, the guide rod 132, and the spring 134, the pin 110 will retract until the pin 110 moves to the position of the pin hole 211. Under the action of the pin support plate 133, the guide rod 132, and the spring 134, the pin 110 will be inserted into the pin hole 211, thereby locking the first connector 100 and the second connector 200.

[0032] When the first connector 100 and the second connector 200 are locked, the lower bottom surface of the clamping part 220 is in contact with the upper bottom surface of the support part 120, the arc-shaped reinforcing part 320 is in contact with the clamping groove 221, and the left and right side plates of the clamping part 220 are in contact with the left and right outer sides of the keel, so that the first connector 100 and the second connector 200 clamp the upper part of the keel 300. Furthermore, in order to make the connection between the keel mounting assembly of this application and the keel 300 more stable, several round holes are provided laterally on the left and right side plates of the clamping part 220. Self-tapping screws can pass through the round holes to connect the side plates of the clamping part 220, the side plates of the keel 300, and the support part 120 together.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
