[0001] The present invention relates to the technical field of ceiling connection, and particularly relates to a stable ceiling connection structure and an installation method. Background Art

[0002] A ceiling refers to a decorative or functional structure installed on the interior top of a building, usually composed of keels, panels or other materials, and is used to hide pipelines, improve the interior aesthetics, improve the acoustic effect or provide functions such as heat insulation.

[0003] A prefabricated ceiling refers to the top decoration of a housing living environment. Simply put, it refers to the decoration of the ceiling and is one of the important parts of interior decoration.

[0004] At present, although the existing stable ceiling connection structures also have certain stability and load-bearing capacity, when facing complex and changeable installation environments and construction requirements, situations such as loosening of connection components and swaying of threaded suspenders often occur, which not only affects the construction efficiency but also poses a potential threat to the safety and durability of the ceiling.

[0005] In view of the above problems, the present invention document proposes a stable ceiling connection structure and an installation method to solve the above-mentioned problems. Summary of the Invention

[0006] The present invention provides a stable ceiling connection structure and an installation method, which solve the disadvantages that the prior art will have situations such as loosening of connection components and swaying of threaded suspenders, which not only affect the construction efficiency but also pose a potential threat to the safety and durability of the ceiling.

[0007] The present invention provides the following technical solutions:

[0008] A stable ceiling connection structure includes:

[0009] A threaded suspender, a suspension member, a main keel, a secondary keel and a cross brace keel, and the suspension member is sleeved on the bottom end of the threaded suspender;

[0010] A strengthening component, which is arranged on the threaded suspender to strengthen the stability of the overall structure and prevent the threaded suspender from swaying when installing the keel.

[0011] In a possible design, the strengthening component includes a connection seat threadedly connected to the outside of the threaded suspension rod. On both sides of the connection seat, movable frames are movably arranged. On both sides of the two movable frames, a cross bar and a hollow rod are respectively fixedly arranged. One end of the cross bar is fixedly provided with a screw rod. One end of the hollow rod is rotatably provided with a first nut. The outside of the screw rod at the outermost side is threadedly connected with a second nut. One side of the second nut is rotatably provided with a first fixing frame. The inner end of the first nut at the outermost side on the other side is threadedly connected with a lead screw. One end of the lead screw is fixedly provided with a second fixing frame.

[0012] In a possible design, second nuts are arranged on both the upper and lower sides of the hanging member. Both of the second nuts are threadedly connected to the threaded suspension rod. A screw hole for fixing the main keel by a screw is formed at the bottom of the hanging member. One side of the hanging member is bendable and provided with a folded plate.

[0013] In a possible design, a limiting block is fixedly arranged at the top end of the threaded suspension rod. An expansion sleeve is sleeved on the outside of the threaded suspension rod below the limiting block. A first nut is threadedly connected to the outside of the threaded suspension rod below the expansion sleeve.

[0014] In a possible design, a first clamping frame can be detachably inserted at both ends of the main keel. A first limiting frame is fixedly arranged at the center of the first clamping frame. Clamping plates are fixedly arranged on both sides of the first limiting frame.

[0015] In a possible design, a plurality of ring frames are sleeved on the outside of the main keel. Blocks are fixedly arranged at the bottoms of the plurality of ring frames. The blocks can be detachably and slidably arranged inside the secondary keel.

[0016] In a possible design, a second clamping frame can be detachably inserted at both ends of the secondary keel. Second limiting frames are fixedly arranged on the outside of the two second clamping frames at the center.

[0017] In a possible design, hanging frames are hung on the outside of the two secondary keels. Plugging frames are fixedly arranged on one side of the two hanging frames close to each other. The two plugging frames can be respectively detachably inserted into both sides of the cross brace keel.

[0018] An installation method of a stable ceiling connection structure includes the following steps:

[0019] S1: Drill holes in sequence at the installation position of the threaded suspension rod. After the drilling is completed, insert the top end of the threaded suspension rod into the drilled hole. When the threaded suspension rod is inserted into the drilled hole, the limiting block and the expansion sleeve on it are both located in the drilled hole. At this time, use a tool to rotate the first nut. When the first nut rotates, it moves upward on the threaded suspension rod and pushes the expansion sleeve to compress it until the expansion sleeve expands and fits tightly with the wall inside the drilled hole. Then, fix and install the threaded suspension rods at different positions in sequence according to the above operation.

[0020] S2: Then threadedly connect the connecting seat to the threaded suspension rod and position it at an appropriate location. Subsequently, sequentially install all the connecting seats on the threaded suspension rod and ensure that all the connecting seats are at the same level (as shown in Figure 1 and Figure 2 ). After all the connecting seats are installed, rotate the cross bar and the hollow rod on one side of each of the two connecting seats respectively to make them approach each other. Then align the screw on the cross bar with the first nut on the hollow rod and rotate the first nut to threadedly connect the screw and the first nut, thereby fixedly connecting the two threaded suspension rods. Subsequently, fixedly connect multiple threaded suspension rods in the same way as described above. Then threadedly connect second nuts to the outside of the multiple screws on the outermost side. After the connection is completed, fix the second nuts to the wall surface through the first fixing bracket. Then threadedly connect the inner ends of the multiple first nuts on the other outermost side to the lead screw. After the connection is completed, fix the lead screw to the other wall surface through the second fixing bracket, thereby fixedly connecting all the threaded suspension rods, making the bearing capacity of the entire structure stronger and more stable. At the same time, the threaded suspension rods will not shake when installing the keel.

[0021] S3: Then sleeved the hanging member on the bottom end of the threaded suspension rod, adjust it to an appropriate position, and threadedly connect second nuts to the outside of the threaded suspension rod on both the upper and lower sides of the hanging member to fix the hanging member. During this process, ensure that the positions of all the hanging members are on the same horizontal line. Subsequently, sleeve multiple ring brackets on the outside of the main keel and ensure that the ring brackets can slide freely. Then place the main keel sleeved with the ring brackets on the hanging members, and bend the folding plate of the main keel on the hanging members to further fix the main keel to prevent it from falling off. When the length of the main keel is insufficient and needs to be spliced, insert one end of the first clamping bracket into the main keel. During the insertion process, clamp the clamping plate on the outside of the main keel. Stop inserting the first clamping bracket when it reaches the position of the first limiting bracket. Subsequently, sleeve the ring brackets on the outside of the main keel and place it on the hanging members in the same way as described above. Then splice the two main keels in the same way as described above. Subsequently, use screws to fix the main keel to the hanging members through the screw holes at the bottom of the hanging members.

[0022] S4: Subsequently, take out the secondary keel and align its opening with the clamping block, and sequentially slide multiple clamping blocks into the inside of the secondary keel to realize the connection between the main keel and the secondary keel. When the length of the secondary keel is insufficient and needs to be spliced, use the second clamping bracket and insert one end of it into the secondary keel. Stop inserting the second clamping bracket when it reaches the position of the second limiting bracket. Then take out another secondary keel and splice the two secondary keels in the same way as described above.

[0023] S5: Then take out the cross brace keel, take out two hanging brackets with plug frames, and insert the two hanging brackets into both ends of the cross brace keel respectively through the plug frames thereon, so that the two hanging brackets and a cross brace keel form an integral body, and hang the cross brace keel between the two secondary keels through the two hanging brackets, thereby realizing the connection between the secondary keel and the cross brace keel.

[0024] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0025] The beneficial effects in the present invention are as follows:

[0026] In the present invention, through the arrangement of the strengthening components, the overall stability of the ceiling connection structure is enhanced, the shaking of the threaded suspension rod during the installation of the keel is effectively prevented, thereby improving the construction efficiency and ensuring the safety and durability of the ceiling.

In this way, the strengthening assembly can fixedly connect a plurality of threaded suspension rods 1 and fix them to the side wall, thereby enhancing the overall stability of the ceiling connection structure and preventing the threaded suspension rod 1 from shaking when installing the keel.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, Embodiment 2 further includes

[0046] Referring to Figures 1-6 , a stable ceiling connection structure, comprising:

[0047] A limiting block is fixedly arranged at the top end of the threaded suspension rod 1 for restricting the upward movement of the expansion sleeve 16. An expansion sleeve 16 is sleeved on the outside of the threaded suspension rod 1 below the limiting block for tightly fitting with the wall to provide stable support. A first nut 17 is threadedly connected to the outside of the threaded suspension rod 1 below the expansion sleeve 16. By rotating the first nut 17, the expansion sleeve 16 can be pushed to expand to achieve fixed connection with the wall.

[0048] Two sets of suspension members 2 are sleeved on the bottom end of the threaded suspension rod 1 for connecting the main keel 3. Nuts two 18 are arranged on both the upper and lower sides of the suspension member 2, and both nuts two 18 are threadedly connected to the threaded suspension rod 1 to fix the position of the suspension member 2. A screw hole 20 is formed at the bottom of the suspension member 2, which is convenient for fixing the main keel 3 on the suspension member 2 through screws. A folding plate 19 is arranged on one side of the suspension member 2 in a bendable manner. After the folding plate 19 is bent, it can preliminarily fix the main keel 3 to prevent the main keel 3 from falling off when placed.

[0049] Both ends of the main keel 3 can be detachably inserted with a first clamping frame 21. The first clamping frame 21 is used to connect two main keels 3. A first limiting frame 22 is fixedly arranged at the center of the first clamping frame 21. The first clamping frame 21 is used to limit the insertion position of the first clamping frame 21. Clamping plates 23 are fixedly arranged on both sides of the first limiting frame 22 to ensure the stable connection between the main keels 3. A plurality of ring frames 24 are sleeved outside the main keel 3. A clamping block 25 is fixedly arranged at the bottom of the ring frame 24. The clamping block 25 can be detachably and slidably arranged inside the secondary keel 4 to realize the connection between the main keel 3 and the secondary keel 4.

[0050] Both ends of the secondary keel 4 can be detachably inserted with a second clamping frame 26. The second clamping frame 26 is used to connect two secondary keels 4. Second limiting frames 27 are fixedly arranged outside the center of the second clamping frame 26 to limit the insertion position of the second clamping frame 26 and ensure the stable connection between the secondary keels 4.

[0051] The cross bracing keel 5 is used to strengthen the lateral stability of the ceiling structure. Hanging frames 28 are hung outside both secondary keels 4. A plugging frame 29 is fixedly arranged on the side of the hanging frame 28 close to each other. The plugging frame 29 can be detachably inserted into both sides of the cross bracing keel 5 to realize the connection between the secondary keel 4 and the cross bracing keel 5.

[0052] The working principle and usage process of this technical solution are as follows:

[0053] First, carefully read the construction drawings to understand the structural layout, dimensions of the ceiling, as well as the installation positions and connection methods of each component. Subsequently, check and prepare the required materials and fittings such as the threaded suspension rod 1, suspension member 2, main keel 3, secondary keel 4, cross bracing keel 5, and strengthening components, etc., to ensure that the quality meets the requirements. Then, use a laser level tester to measure the overall horizontal vertical line of the room, pop up the range line of the ceiling on the wall with a chalk line, and then determine the installation position of the threaded suspension rod 1 according to the requirements of the construction drawings;

[0054] Subsequently, drill holes successively at the installation positions of the threaded suspension rods 1. After the drilling is completed, insert the top end of the threaded suspension rod 1 into the drilled holes. When the threaded suspension rod 1 is inserted into the drilled holes, the limit blocks and the expansion sleeves 16 thereon are both located within the drilled holes. At this time, use a tool to rotate the first nut 17. When the first nut 17 rotates, it moves upward on the threaded suspension rod 1 and pushes the expansion sleeve 16 to compress it until the expansion sleeve 16 expands and fits tightly against the wall inside the drilled hole. Then, fix and install the threaded suspension rods 1 at different positions in sequence according to the above operations;

[0055] Then thread the connecting seat 6 onto the threaded suspension rod 1 and position it appropriately. Subsequently, install all the connecting seats 6 onto the threaded suspension rod 1 in sequence and make all the connecting seats 6 at the same level (as Figure 1 and Figure 2 shown). When all the connecting seats 6 are installed, rotate the cross bars 8 and the hollow rods 10 on one side of the two connecting seats 6 respectively to make them approach each other. Subsequently, align the screw rod 9 on the cross bar 8 with the first nut 11 on the hollow rod 10 and rotate the first nut 11 to thread-connect the screw rod 9 and the first nut 11, thereby fixedly connecting the two threaded suspension rods 1. Subsequently, fixedly connect multiple threaded suspension rods 1 to each other in sequence according to the above operations. Subsequently, thread the second nuts 12 onto the outer sides of the multiple screw rods 9 at the outermost sides. After the connection is completed, fix the second nuts 12 to the wall surface through the first fixing frames 13. Subsequently, thread the inner ends of the multiple first nuts 11 at the other outermost side onto the lead screws 14. After the connection is completed, fix the lead screws 14 through the second fixing frames 15. Fix them to the wall surface on the other side, thereby fixedly connecting all the threaded suspension rods 1 to make the bearing capacity of the entire structure stronger and more stable. At the same time, the threaded suspension rods 1 will not shake when installing the keels;

[0056] Then sleeved the hanging parts 2 onto the bottom ends of the threaded suspension rods 1, adjust them to appropriate positions, and thread-connect the second nuts 18 onto the outer sides of the threaded suspension rods 1 on both the upper and lower sides of the hanging parts 2, thereby fixing the hanging parts 2. During this process, make sure that the positions of all the hanging parts 2 are on the same horizontal line. Subsequently, sleeved multiple ring frames 24 onto the outer sides of the main keels 3 and ensure that the ring frames 24 can slide freely. Place the main keels 3 sleeved with the ring frames 24 on the hanging parts 2, and bend the folding plates 19 of the main keels 3 on the hanging parts 2 to further fix the main keels 3 to prevent them from falling off. When the length of the main keel 3 is insufficient and needs to be spliced, insert one end of the first clamping frame 21 into the main keel 3. During the insertion process, clamp the clamping plate 23 on the outer side of the main keel 3. When the first clamping frame 21 is inserted to the position of the first limiting frame 22, stop inserting the first clamping frame 21. Subsequently, sleeve the ring frames 24 onto the outer sides of the main keels 3 and place them on the hanging parts 2 according to the above operations. Subsequently, splice the two main keels 3 according to the above operations. Subsequently, through the screw holes 20 at the bottoms of the hanging parts 2, use screws to fix the main keels 3 to the hanging parts 2;

[0057] Subsequently, take out the secondary keel 4 so that its opening is aligned with the clamping block 25, and slide multiple clamping blocks 25 into the interior of the secondary keel 4 in sequence to achieve the connection between the main keel 3 and the secondary keel 4. When the length of the secondary keel 4 is insufficient and splicing is required, use the second clamping frame 26 and insert one end of it into the secondary keel 4. Stop inserting the second clamping frame 26 when it is inserted to the position of the second limiting frame 27. Subsequently, take out another secondary keel 4 and splice the two secondary keels 4 according to the above operation;

[0058] Then take out the cross brace keel 5, take out two hanging frames 28 with plug frames 29, and insert the two hanging frames 28 into both ends of the cross brace keel 5 respectively through the plug frames 29 thereon, so that the two hanging frames 28 and a cross brace keel 5 form an integral body, and hang the cross brace keel 5 between the two secondary keels 4 through the two hanging frames 28, thereby achieving the connection between the secondary keel 4 and the cross brace keel 5.

[0059] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.

When the length of the secondary keel (4) is not enough and needs to be spliced, the second clamping frame (26) is used and one end thereof is inserted into the secondary keel (4). When the second clamping frame (26) is inserted into the position of the second limit frame (27), the insertion of the second clamping frame (26) is stopped, and then another secondary keel (4) is taken out and the two secondary keels (4) are spliced ​​according to the above operation. S5: Then, the cross bracing keel (5) is taken out, and two hangers (28) with plug frames (29) are taken out, and the two hangers (28) are respectively inserted into the two ends of the cross bracing keel (5) through the plug frames (29) thereon, so that the two hangers (28) and one cross bracing keel (5) form a whole, and the cross bracing keel (5) is hung between the two secondary keels (4) through the two hangers (28), thereby realizing the connection between the secondary keel (4) and the cross bracing keel (5).
