[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A sealed keel system, such as Figures 1-5 As shown, the system includes several main keels 1 and several secondary keels 2. The main keels 1 are fixed to the floor slab below by hangers. The secondary keels 2 are fixedly connected to the main keels 1 by hangers. Several partitions 5 are provided between adjacent secondary keels 2. The two ends of the partitions 5 are welded to the side walls of two adjacent secondary keels 2 respectively. The partitions 5 are evenly distributed along the length of the secondary keels 2, and the distance between adjacent partitions 5 is the same as the distance between adjacent secondary keels 2. A connecting component for snapping onto the top plate 3 is provided between adjacent partitions 5 along the length of the secondary keels 2. A cavity 6 is opened in the connecting component, and sealant is injected into the cavity 6. A limiting component is provided above the connecting component. The table below shows the limiting component. The upper surface of the connecting component abuts against the lower surface of the connecting component. When the connection is not being made, the limiting component can prevent the connecting component from rotating upward. When the top plate 3 needs to be installed, the operator applies a pushing force to the lower surface of the top plate 3 to move the top plate 3 upward. During the upward movement, the top plate 3 first contacts the limiting component, causing the limiting component to lose its restraint on the connecting component. The connecting component rotates upward 90 degrees and snaps the top plate 3 between the two partitions 5. At this time, the connecting component and the groove 4 of the top plate 3 are engaged, and the cavity 6 is connected to the outside. The sealant in the cavity 6 flows into the space between the connecting component and the top plate 3, filling the gap between the top plate 3 and the connecting component, and increasing the sealing effect of the ceiling.

[0021] like Figures 1-4As shown, the connecting assembly includes connector one and connector two. Connector two has the same structure as connector one. Connector one is rotatably connected to partition 5. Several receiving grooves 7 are recessed inward on the side wall of partition 5. An elastic element 8 is welded to the upper surface of connector one. The end of elastic element 8 away from connector one is welded to the inner wall of receiving groove 7. When not installed, elastic element 8 is in a fully stretched state, and the tension of elastic element 8 on connector one is at its maximum. When the restraint of the limiting assembly on connector one is removed, connector one rotates 90 degrees upward under the tension of elastic element 8, so that the upper surface of connector one abuts against the side wall of partition 5. At this time, elastic element 8 is stored in receiving groove 7 and is still in a stretched state, so that elastic element 8 can maintain the state of applying tension to connector one. Connector two is rotatably connected to the keel. Several receiving grooves 13 are recessed inward on the side wall of secondary keel 2. Elastic element 2 9 is welded to the upper surface of connector 2. The end of elastic element 2 9 away from connector 2 is welded to the inner wall of storage groove 2 13. When not installed, elastic element 2 9 is in a fully stretched state, at which time the tension of elastic element 2 9 on connector 2 is at its maximum. When the restraint of the limiting component on connector 2 is removed, connector 2 rotates 90 degrees upward under the tension of elastic element 2 9, so that the upper surface of connector 2 abuts against the side wall of partition 5. At this time, elastic element 2 9 is stored in storage groove 2 13 and is still in a stretched state, so that elastic element 2 9 can continue to apply tension to connector 2. Each storage groove 1 7 and storage groove 2 13 is provided with two elastic elements 1 8 and two elastic elements 2 9 respectively. Both elastic elements 1 8 and two elastic elements 2 9 are set as strong springs, which increases the sum of the tension of elastic element 1 8 on the same connector 1 and increases the sum of the tension of elastic element 2 9 on the same connector 2.

[0022] like Figures 1-4As shown, the cross-sectional shape of connector one is L-shaped. Connector one includes a connecting plate one 10 and a snap-fit ​​plate one 11, which are integrally formed. Connecting plate one 10 and snap-fit ​​plate one 11 are perpendicular to each other. Connecting plate one 10 is rotatably connected to partition 5. Elastic member one 8 is welded to the upper surface of connecting plate one 10. When top plate 3 is not installed, connecting plate one 10 is in a horizontal state, and the lower surface of the limiting component abuts against the upper surface of connecting plate one 10. When the binding force of the limiting component on connecting plate one 10 disappears, connecting plate one 10 is pulled upward by elastic member one 8 and rotates until it abuts against the side wall of partition 5. During this process, connecting plate one 10 drives snap-fit ​​plate one 11 to rotate. During the rotation, snap-fit ​​plate one 11 applies an upward thrust to top plate 3 to complete the installation of top plate 3. At this time, snap-fit ​​plate one 11 abuts against the inner top surface of groove 4. Connector two is packaged. The assembly includes a second connecting plate and a second snap-fit ​​plate, which are integrally formed. The second connecting plate is rotatably connected to the secondary keel 2. The second elastic element 9 is welded to the upper surface of the second connecting plate. When the top plate 3 is not installed, the second connecting plate is in a horizontal state, and the lower surface of the limiting component abuts against the upper surface of the second connecting plate. When the restraining force of the limiting component on the second connecting plate disappears, the second connecting plate is pulled upward by the second elastic element 9 and rotates until it abuts against the side wall of the secondary keel 2. During this process, the second connecting plate drives the second snap-fit ​​plate to rotate. During the rotation, the second snap-fit ​​plate applies an upward thrust to the top plate 3 to complete the installation of the top plate 3. At this time, the second snap-fit ​​plate abuts against the inner top surface of the groove 4. The height of the first connecting plate 10 is greater than the distance between the end of the first connecting plate 10 away from the partition 5 and the end of the first snap-fit ​​plate 11 away from the partition 5, which reduces the probability of the connecting component getting stuck with the top plate 3 during the upward rotation.

[0023] like Figures 1-5As shown, the limiting component includes a limiting member one and a limiting member two with the same structure as limiting member one. Limiting member one is slidably connected to the partition 5 via a sliding groove one 12. Limiting member one includes a blocking strip one 14 and a slider one 15. Slider one 15 is slidably connected to the blocking strip one 14 via a sliding groove one 16. The cross-sectional shape of sliding groove one 16 and slider one 15 is T-shaped. The end of the slider near the partition 5 is welded to the inner wall of sliding groove one 12 via an elastic element three 17. The elastic element three 17 is set as a spring. When the top plate 3 is not installed, the blocking strip one 14 extends out of sliding groove one 12, and the slider one 15 extends out of sliding groove one 16. At this time, the lower surface of the blocking strip one 14 is flush with the upper surface of the connecting plate one 10. The slider 15, near the partition 5, abuts against the side wall of the connecting plate 10. The elastic element 17 is in a stretched state. At this time, the slider 15 is obstructed by the connecting plate 10, preventing the blocking strip 14 from moving under the tension of the elastic element 17. Simultaneously, the blocking strip 14 also prevents the connecting plate 10 from rotating upwards under the tension of the elastic element 8. The limiting element 2 is slidably connected to the secondary keel 2 via the sliding groove 2. The limiting element 2 includes the blocking strip 2 and the slider 2. The slider 2 is slidably connected to the blocking strip 2 via the sliding groove 16. Both the sliding groove 2 and the slider 2 have a T-shaped cross-section. The end of the slider near the partition 5 is welded to the inner wall of the sliding groove 2 via the elastic element 17. Next, when the top plate 3 is not installed, the second blocking strip extends out of the second sliding groove, and the second slider extends out of the second sliding groove. At this time, the lower surface of the second blocking strip abuts against the upper surface of the second connecting plate, and the side of the second slider near the partition 5 abuts against the side wall of the second connecting plate. The third elastic element 17 is in a stretched state. At this time, the second slider is obstructed by the second connecting plate, preventing the second blocking strip from moving under the tension of the third elastic element 17. At the same time, the second blocking strip also prevents the second connecting plate from rotating upward under the tension of the second elastic element 9. The upper surface of the top plate 3 is integrally formed with four protrusions 18. The protrusions 18 and the first slider 15 are in the same relative position. When the top plate 3 is pushed upward by the operator, the protrusions 18 on the top plate 3 move upward. 8 contacts slider 15 and slider 2 and exerts a pushing force on slider 15 and slider 2, causing slider 15 and slider 2 to slide upward on the inner walls of slide groove 16 and slide groove 2 respectively and be completely retracted into slide groove 16 and slide groove 2. At this time, the resistance of blocking strip 14 disappears, and blocking strip 14 and blocking strip 2 are pulled by elastic element 3 17 respectively and slide on the inner walls of slide groove 12 and slide groove 2, and are completely retracted into slide groove 12 and slide groove 2. This makes the resistance of blocking strip 14 and blocking strip 2 on connecting plate 10 and connecting plate 2 disappear, and connecting plate 10 and connecting plate 2 are pulled upward by elastic element 1 8 and elastic element 2 9 respectively and rotate.

[0024] like Figures 1-5As shown, cavity 6 is set inside connecting plate 10 and connecting plate 2. Cavity 6 is connected to the outside through several through slots 19. A thin film 20 for sealing cavity 6 is adhered to the inner wall of through slot 19. The thin film 20 is made of polyethylene resin. Several protrusions 21 are fixedly connected to the four side walls of top plate 3. The protrusions 21 correspond one-to-one with through slots 19. During the process of connecting components rotating to engage top plate 3, the protrusions 21 enter through slots 19 and puncture the thin film 20, so that cavity 6 is connected to the outside. The sealant in cavity 6 flows into the space between connecting components and top plate 3, filling the gap between connecting components and top plate 3, and increasing the sealing effect of the ceiling. A sealing element is set between adjacent connecting parts 1 and 2. The sealing element is made of flexible material. When connecting parts 1 and 2 rotate to fit with partition 5 and secondary keel 2, the sealing element seals the gap between adjacent connecting parts 1 and 2, ensuring the overall sealing of the ceiling.

[0025] Working principle: A sealed keel system. During installation, the construction personnel apply an upward thrust to the top plate 3. The protrusion 18 on the top plate 3 moves and abuts against sliders 15 and 2, generating an upward thrust on them. This causes sliders 15 and 2 to fully retract into the sliding grooves 16 and 2. At this time, the tension on the elastic element 3 17 disappears, causing it to rebound and generate tension on the blocking strips 14 and 2, causing them to retract into the sliding grooves. Inside the sliding groove 12 and the sliding groove 2, the tension on the elastic element 18 and the elastic element 29 disappears. The elastic element 18 and the elastic element 29 rebound and generate tension on the connecting plate 10 and the connecting plate 2, causing the connecting plate 10 and the connecting plate 2 to rotate 90 degrees and clamp the top plate 3 between the partition plate 5 and the secondary keel 2. During this process, the protrusions 21 around the top plate 3 puncture the membrane 20, allowing the cavity 6 to communicate with the outside. The sealant in the cavity 6 flows into the gap between the secondary keel 2, the partition plate 5 and the top plate 3 to enhance the sealing effect of the keel system.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
