Description

Technical Field

[0001] This utility model relates to the field of wood keel connection technology, and in particular to a ceiling wood keel connection structure. Background Technology

[0002] Wooden joist connection is a technique used in architectural decoration to combine multiple wooden joists into a stable structure. Through different connection methods, the wooden joists can play a supporting and shaping role.

[0003] Light steel keel comes in V-shaped, C-shaped, T-shaped, L-shaped, and U-shaped keel according to its cross-sectional shape. For U-shaped keel, when connecting the wall wooden keel, the two are perpendicular to each other, which requires cutting and bending the ends of the keel to create a short connecting side. Then, holes are drilled on the short connecting side, and screws are used for connection. The construction is slow, time-consuming, labor-intensive, and difficult to operate. The finished product is irregular and the cost is high.

[0004] The existing patent (publication number: CN211949163U) is a connector for connecting U-shaped light steel keel and wall wood keel. During construction, keel clamps are used to clamp and connect the two ear plates to the two side walls of the light steel keel. Screws are used to fix the connector to the wall wood keel, thus realizing the connection between the U-shaped light steel keel and the wall wood keel. Compared with the existing technology, it is faster to construct, simpler to operate, has a neater connection, and lower cost.

[0005] To address the aforementioned issues, existing patents offer solutions. However, some existing cross-connection structures for ceiling wooden joists require the use of a pneumatic nail gun to drive in multiple pneumatic nails for connection. The pneumatic nail gun also requires an external air pump, which is inconvenient and makes it difficult to position the wooden joists after the cross connection, affecting the subsequent stability of the wooden joists.

[0006] Therefore, a connection structure for ceiling wooden joists is proposed. Utility Model Content

[0009] The limiting mechanism includes a locking block, a limiting plate, a stud, and an internal hexagon block. The stud is threadedly connected inside the locking block. The top of the limiting plate is rotatably connected to the bottom of the stud. The bottom of the internal hexagon block is fixedly connected to the top of the stud.

[0010] Preferably, the positioning mechanism includes a plurality of positioning holes, a positioning plate, a screw, and a fixed barrel. The positioning holes are formed inside the positioning plate, the top of the screw is fixedly connected to the bottom of the positioning plate, and the bottom of the screw extends into the interior of the fixed barrel and is threadedly connected to the interior of the fixed barrel.

[0011] Preferably, a connecting frame is fixedly connected to the bottom of the fixed bucket, and the bottom of the connecting frame is fixedly connected to the surface of the top card block.

[0012] Preferably, the surface of the screw is fixedly fitted with an anti-slip sleeve.

[0013] Preferably, the front and rear sides of the top block and both sides of the bottom block are fixedly connected to the rails, and the blocks are movably engaged inside the rails.

[0027] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A ceiling joist connection structure includes horizontal joists 1 and vertical joists 2. A connecting frame 6 is provided at the bottom of the horizontal joist 1 and the top of the vertical joist 2. A limiting mechanism 4 is provided at the top of the horizontal joist 1 and the bottom of the vertical joist 2. A positioning mechanism 5 is provided at the top of the top limiting mechanism 4.

[0030] The limiting mechanism 4 includes a locking block 401, a limiting plate 402, a stud 403, and an internal hexagon block 404. The stud 403 is threadedly connected to the inside of the locking block 401. The top of the limiting plate 402 is rotatably connected to the bottom of the stud 403, and the bottom of the internal hexagon block 404 is fixedly connected to the top of the stud 403.

[0031] In this embodiment: By placing the horizontal joists 1 and vertical joists 2 in the top and bottom connecting brackets 6 respectively, inserting the locking block 401 into the locking rail 7, and using an external hex wrench to rotate the hexagonal block 404, the stud 403 rotates within the locking block 401, causing the limiting plate 402 to move downwards. The second anti-slip cone 10 on its surface makes close contact with the horizontal joists 1 and vertical joists 2, while the first anti-slip cone 8 on the inner wall of the locking block 401 bites the wooden joists, providing double anti-slip reinforcement and enhancing the fixing effect. At this time, the locking block 401 is stable within the locking rail 7, eliminating the need for nailing with a pneumatic nail gun, thus improving safety and convenience. The screw 503 is rotated by holding the anti-slip sleeve 9. 503 uses internal thread transmission within the fixed bucket 504 to move the positioning plate 502 up and down. The height of the positioning plate 502 is adjusted according to the actual positions of the horizontal and vertical wooden joists 1 and 2, so that its top is flush with the top of the building wall. Then, external bolts are used to fix it through the positioning hole 501, completing the positioning of the horizontal and vertical wooden joists 1 and 2, ensuring stability in subsequent use. This solves the problem that some existing cross-connection structures for ceiling wooden joists require the use of a pneumatic nail gun to drive in multiple pneumatic nails for connection. The pneumatic nail gun also requires an external air pump, which is inconvenient and makes it difficult to position the wooden joists after the cross connection, affecting the subsequent stability of the wooden joists.

[0032] Specifically, such as Figure 5 As shown, the positioning mechanism 5 includes several positioning holes 501, a positioning plate 502, a screw 503, and a fixed barrel 504. The positioning holes 501 are opened inside the positioning plate 502. The top of the screw 503 is fixedly connected to the bottom of the positioning plate 502, and the bottom of the screw 503 extends into the interior of the fixed barrel 504 and is threadedly connected to the interior of the fixed barrel 504.

[0033] Specifically, such as Figure 2 and Figure 5 As shown, a connecting frame 3 is fixedly connected to the bottom of the fixed bucket 504, and the bottom of the connecting frame 3 is fixedly connected to the surface of the top card block 401.

[0034] Specifically, such as Figure 5 As shown, the surface of the screw 503 is fixed with an anti-slip sleeve 9.

[0035] In this embodiment: by holding the anti-slip sleeve 9 and rotating the screw 503, the screw 503 rotates within the fixed barrel 504, causing the positioning plate 502 to move up and down along the screw 503, so that the top of the positioning plate 502 contacts the top of the building wall. Then, the external bolt can be used to fix the positioning plate 502 through the positioning hole 501, thereby completing the positioning of the horizontal joists 1 and the vertical joists 2, making the horizontal joists 1 and the vertical joists 2 more stable in subsequent use.

[0036] Specifically, such as Figure 2 , Figure 3 and Figure 4As shown, the front and rear sides of the top block 401 and both sides of the bottom block 401 are fixedly connected to the rails 7, and the block 401 is movably engaged inside the rails 7.

[0037] Specifically, such as Figure 1 and Figure 3 As shown, the inner wall of the card block 401 is fixedly connected with a first anti-slip cone 8. There are several first anti-slip cones 8, which are evenly distributed on the inner wall of the card block 401. The surfaces of the horizontal keel 1 and the vertical keel 2 are in close contact with the surface of the first anti-slip cone 8.

[0038] Specifically, such as Figure 1 and Figure 6 As shown, a second anti-slip cone 10 is fixedly connected to the surface of the limiting plate 402. There are several second anti-slip cones 10 and they are evenly distributed on the surface of the limiting plate 402. The surfaces of the horizontal keel 1 and the vertical keel 2 are in close contact with the surface of the second anti-slip cone 10.

[0039] In this embodiment: by inserting the locking block 401 into the inside of the rail 7 and locking the stud 403, the locking block 401 can be stably placed inside the rail 7, and the horizontal keel 1 and the vertical keel 2 are stably clamped and fixed by the first anti-slip cone 8 and the second anti-slip cone 10.

[0040] Specifically, such as Figure 2 and Figure 5 As shown, the positioning plate 502, screw 503, fixing barrel 504 and connecting frame 6 are all made of hard, inelastic metal.

[0041] In this embodiment, components such as positioning plate 502 and screw 503 are made of hard, inelastic metal, which can effectively transfer and distribute loads, ensuring that the horizontal keel 1 and the vertical keel 2 are firm and meeting the stability and safety requirements of ceiling construction.

[0042] Working principle: By moving the horizontal joist 1 into the top connecting frame 6 and the vertical joist 2 into the bottom connecting frame 6, the locking block 401 is movably inserted into the rail 7. Then, using an external hex wrench to rotate the hexagonal block 404, the stud 403 rotates within the locking block 401. Because the limiting plate 402 is rotatably connected to the bottom of the stud 403, the limiting plate 402 does not rotate with the stud 403, but gradually moves downwards. The second anti-slip cone 10 on the surface of the limiting plate 402 is in close contact with the surfaces of the horizontal joist 1 and the vertical joist 2. As the limiting plate 402 moves downward, the second anti-slip cone 10 penetrates to a certain depth into the horizontal and vertical joists 1 and 2, increasing friction. Simultaneously, the first anti-slip cone 8 on the inner wall of the locking block 401 tightly grips the horizontal and vertical joists 1 and 2. This double anti-slip design enhances the fixing effect between the locking block 401 and the horizontal and vertical joists 1 and 2. At this point, the locking block 401 will not slide freely inside the locking rail 7, eliminating the need for an air pump to drive a nail gun to nail the horizontal and vertical joists 1 and 2, thus improving safety and convenience. The screw 50 can be rotated by holding the anti-slip sleeve 9. 3. The screw 503 rotates within the fixed bucket 504, causing the positioning plate 502 to move up and down along the screw 503. Based on the actual positions of the horizontal timber joists 1 and 2, the positioning plate 502 is adjusted to a suitable height so that its top contacts the top of the building wall. External bolts can then be used to fix the positioning plate 502 through the positioning holes 501, thus completing the positioning of the horizontal timber joists 1 and 2, making their subsequent use more stable. The positioning plate 502, screw 503, fixed bucket 504, and connecting frame 6 all adopt... Made of rigid, inelastic metal, it possesses high strength and stability, effectively transferring and distributing the load on the horizontal and vertical wooden joists 1 and 2. This ensures that the horizontal and vertical wooden joists 1 and 2 remain firm during use, preventing loosening or deformation. It meets the stability and safety requirements of ceiling construction and solves the problem of existing cross-connection structures for ceiling wooden joists, which require the use of a pneumatic nail gun to drive in multiple pneumatic nails for connection. The pneumatic nail gun also requires an external air pump, which is inconvenient and makes it difficult to position the wooden joists after the cross connection, affecting the subsequent stability of the wooden joists.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
