Description

Technical Field

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

[0002] In the field of architectural decoration, suspended ceilings are often required on roofs. The general purpose of suspended ceilings is decoration, especially in residential settings. However, for public places such as schools, shopping malls, hotels, hospitals, and government offices, the suspended ceilings are generally referred to as commercial suspended ceilings. In humid areas, suspended ceilings are constantly exposed to moisture, allowing airborne moisture to seep into them, which is detrimental to their long-term use. Furthermore, existing suspended ceiling structures are complex and inconvenient to install, increasing the workload for workers.

[0003] Chinese utility model patent CN212427727U discloses a building ceiling, relating to the field of building ceiling technology. It includes a base plate, a connecting column connected to the top of the base plate, and support frames connected to both sides of the connecting column. First mounting blocks are connected to both sides of the top of the connecting column, and first bolts are installed inside the first mounting blocks. A locking block is connected to the bottom of the connecting column, and third mounting blocks are connected to both sides of the bottom of the connecting column, with third bolts installed inside the third mounting blocks. This utility model, through the design of the base plate, heat insulation layer, moisture-absorbing layer, and support frames, improves the heat insulation effect of the ceiling by utilizing the heat insulation layer connected to the bottom of the base plate, improves the moisture-proof performance of the ceiling by utilizing the moisture-absorbing layer at the bottom of the heat insulation layer, and uses the support frames to fix the base plate to the ceiling, making the connection between the base plate and the ceiling via the connecting column more stable, thus improving the stability of the ceiling and enhancing its protective performance.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the device fixes the base plate with a third bolt. In actual use, one worker needs to continuously lift the base plate while another worker installs the third bolt. This makes single-person operation difficult, installation challenging, and places high demands on the worker lifting the base plate, posing certain safety hazards. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a suspended ceiling for buildings.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a building ceiling includes a connecting column and a support frame fixed on the connecting column. An installation block is fixed on the bottom surface of the connecting column. A base plate is connected to the lower end of the installation block. A sliding groove is formed on the upper surface of the base plate. The installation block is slidably connected to the sliding groove. A heat insulation layer is provided on the bottom surface of the base plate. A moisture-absorbing layer is provided on the bottom surface of the heat insulation layer. Two mutually symmetrical fixing plates are fixed on the side wall of the connecting column. Fixing bolts are provided on the fixing plates. A fixing component for fixing the installation block is provided on the base plate.

[0007] By adopting the above technical solution, when workers need to install the base plate, they must fix the support frame and connecting column together, and ensure the upper end of the connecting column is pressed against the inner ceiling wall of the building. Further, workers can use bolts to fix the support frame to the roof, thus stabilizing the connecting column. Then, workers simply support the base plate and move it upwards to connect the mounting block and the sliding groove, thus initially stabilizing the base plate under the action of the fixing components. Further, workers only need to connect the fixing bolts to the fixing plate to fix the connecting column and the base plate together. In this process, a single person can complete the installation of the base plate; the operation is simple and has low risk.

[0008] Furthermore, fixing grooves are provided on the two opposite side walls of the mounting block. The fixing assembly includes two fixing blocks that are slidably disposed in the two fixing grooves, two compression springs with one end fixed to the side wall of the two fixing blocks respectively, and two connecting ropes with one end fixed to the side wall of the two fixing blocks respectively. The other ends of the two compression springs are fixed to the inner wall of the two fixing grooves respectively.

[0009] Furthermore, fixing holes are provided on the two inner walls opposite to each other of the slide groove, and an inclined surface is provided on the edge where the bottom surface of the fixing block intersects with the side wall away from the compression spring.

[0010] By adopting the above technical solution, when workers need to install the base plate, they need to connect the connecting column to the roof and move the base plate upwards. This allows the sliding groove to gradually approach and connect with the mounting block, thus pressing the base plate against the inclined surface. This allows the fixing block to move completely into the fixing groove under the action of the base plate. Subsequently, when the mounting block is fully moved into the sliding groove, the fixing groove and fixing hole are aligned, allowing the fixing block to connect with the fixing hole under the action of the compression spring. This ensures the base plate remains stable under the action of the fixing block, eliminating the need for workers to continuously apply a force to maintain stability on the base plate.

[0011] Furthermore, a rotating groove is provided on the side wall of the connecting column, and a rotating block is rotatably arranged in the rotating groove. The other ends of the two connecting ropes are fixed to the inner wall of the rotating block.

[0012] By adopting the above technical solution, when workers need to replace the base plate, they need to separate the mounting block from the slide groove. At this time, the worker needs to rotate the rotating block, which causes the connecting rope, fixed to the inner wall of the rotating block, to move along with the rotating block, thereby separating the fixing block from the fixing hole under the action of the connecting rope. Then, the base plate automatically moves downwards under the action of gravity, further separating the slide groove from the mounting groove, thus reducing the difficulty of operation for workers.

[0013] Furthermore, the inner wall of the rotating block is provided with a receiving groove for accommodating the connecting rope.

[0014] By adopting the above technical solution, the receiving slot reduces the probability of the rotating block getting stuck when the operator rotates it, thereby improving the operator's user experience.

[0015] Furthermore, a first limiting groove is provided on the side wall of the rotating block, and a sliding rod is slidably disposed in the first limiting groove. A second limiting groove matching the sliding rod is provided on the inner wall of the rotating groove.

[0016] By adopting the above technical solution, when the base plate needs to be replaced, the operator simply rotates the rotating block, causing the first limiting groove to gradually approach the second limiting groove and eventually align with it. Then, the operator only needs to press the sliding rod to connect it with the second limiting groove, thus stabilizing the rotating block under the action of the sliding rod. The operator does not need to continuously apply a force to maintain stability on the rotating block, thereby reducing the difficulty of operation.

[0017] Furthermore, a connecting groove is provided on the side wall of the rotating block, which communicates with the first limiting groove, and a fixing rope for blocking the sliding rod is provided in the connecting groove.

[0018] By adopting the above technical solution, the fixing rope reduces the probability of the sliding rod separating from the first limiting groove, thereby improving the stability of the device.

[0019] Furthermore, a handle is fixed to the end of the sliding rod to reduce the difficulty for workers to move the sliding rod.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when workers need to install the base plate, they must fix the support frame and the connecting column together, and ensure that the upper end of the connecting column is pressed against the inner ceiling wall of the building. Furthermore, workers can use bolts to fix the support frame to the roof of the building, thus stabilizing the connecting column. Subsequently, workers only need to support the base plate and move it upwards to connect the mounting block and the sliding groove, thus initially stabilizing the base plate under the action of the fixing components. Further, workers only need to connect the fixing bolts to the fixing plate to fix the connecting column and the base plate together. In this process, a single person can complete the installation of the base plate; the operation is simple and the risk is low.

[0022] 2. In this application, when workers need to install the base plate, they need to connect the column to the roof and move the base plate upwards. This allows the sliding groove to gradually approach and connect with the mounting block, thus pressing the base plate against the inclined surface. This allows the fixing block to move completely into the fixing groove under the action of the base plate. Subsequently, when the mounting block is completely moved into the sliding groove, the fixing groove and fixing hole are aligned, allowing the fixing block to connect with the fixing hole under the action of the compression spring. This ensures the base plate remains stable under the action of the fixing block, eliminating the need for workers to continuously apply a force to maintain stability to the base plate.

[0023] 3. In this application, when the worker needs to replace the base plate, the worker needs to separate the mounting block from the slide groove. At this time, the worker needs to rotate the rotating block, which will cause the connecting rope fixed to the inner wall of the rotating block to move with the rotating block, thereby separating the fixing block from the fixing hole under the action of the connecting rope. At this time, the base plate will automatically move downward under the action of gravity, thereby separating the slide groove from the mounting groove, thus reducing the difficulty of operation for the worker.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-6 As shown in the illustration, this application discloses a building ceiling, including a connecting column 1, a support frame 11, a mounting block 2, a base plate 21, a heat insulation layer 31, a moisture-absorbing layer 4, a fixing plate 41, fixing bolts 5, a fixing assembly 6, a rotating block 71, a sliding rod 82, and a fixing rope 85. The support frame 11 is fixed to the connecting column 1. The mounting block 2 is a rectangular block structure and is fixed to the bottom surface of the connecting column 1. The base plate 21 is a rectangular plate structure, and the lower end of the base plate 2 is connected to the mounting block 2. A groove 3 is provided on the upper surface of the base plate 21, and the mounting block 2 is slidably connected to the groove 3. The heat insulation layer 31 is disposed on the bottom surface of the base plate 21, and the moisture-absorbing layer 4 is disposed on the bottom surface of the heat insulation layer 31. The fixing plate 41 is a rectangular plate structure, and two fixing plates 41 are provided and symmetrically disposed on the side wall of the connecting column 1. The fixing bolts 5 are disposed on the fixing plate 41.

[0033] Fixing grooves 51 are provided on the two opposite side walls of the mounting block 2. The fixing assembly 6 is set on the base plate 21 and is used to fix the mounting block 2. The fixing assembly 6 includes a fixing block 61, a compression spring 62, and a connecting rope 63. The fixing block 61 is a rectangular block structure. There are two fixing blocks 61, which are slidably set in the two fixing grooves 51 respectively. There are two compression springs 62. One end of the two compression springs 62 is fixed to the side wall of the two fixing blocks 61 respectively, and the other end of the two compression springs 62 is fixed to the inner wall of the two fixing grooves 51 respectively. There are two connecting ropes 63. One end of the two connecting ropes 63 is fixed to the side wall of the two fixing blocks 61 respectively. Fixing holes 64 are provided on the two opposite inner walls of the sliding groove 3. An inclined surface is provided on the edge where the bottom surface of the fixing block 61 intersects with the side wall away from the compression spring 62.

[0034] When workers need to install the base plate 21, they need to connect the connecting column 1 to the roof and move the base plate 21 upwards. This allows the sliding groove 3 to gradually approach and connect with the mounting block 2, thus pressing the base plate 21 against the inclined surface. This allows the fixing block 61 to move completely into the fixing groove 51 under the action of the base plate 21. Subsequently, when the mounting block 2 is completely moved into the sliding groove 3, the fixing groove 51 aligns with the fixing hole 64, allowing the fixing block 61 to connect with the fixing hole 64 under the action of the compression spring 62. This keeps the base plate 21 stable under the action of the fixing block 61, eliminating the need for workers to continuously apply a force to maintain stability to the base plate 21.

[0035] A rotating groove 7 is provided on the side wall of the connecting column 1. The rotating block 71 is a block structure with a circular cross-section. The rotating block 71 is rotatably set in the rotating groove 7, and the other ends of the two connecting ropes 63 are fixed to the inner wall of the rotating block 71.

[0036] When the base plate 21 needs to be replaced, the worker needs to separate the mounting block 2 from the slide groove 3. At this time, the worker needs to rotate the rotating block 71, which will cause the connecting rope 63, which is fixed to the inner wall of the rotating block 71, to move along with the rotating block 71. This allows the fixing block 61 to separate from the fixing hole 64 under the action of the connecting rope 63. Then, the base plate 21 automatically moves downwards under the action of gravity, further separating the slide groove 3 from the mounting groove, thus reducing the difficulty of operation for the worker.

[0037] To reduce the probability of the rotating block 71 getting stuck when the operator rotates it, thereby improving the operator's user experience, a receiving groove 8 for accommodating the connecting rope 63 is provided on the inner wall of the rotating block 71.

[0038] The rotating block 71 has a first limiting groove 81 on its side wall. The sliding rod 82 is a round rod structure. The sliding rod 82 is slidably disposed in the first limiting groove 81. The inner wall of the rotating groove 7 has a second limiting groove 83 that matches the sliding rod 82.

[0039] When the base plate 21 needs to be replaced, the operator rotates the rotating block 71, causing the first limiting groove 81 to gradually approach the second limiting groove 83 and eventually align with it. Then, the operator simply presses the sliding rod 82 to connect it to the second limiting groove 83, thus stabilizing the rotating block 71 under the action of the sliding rod 82. This eliminates the need for the operator to continuously apply force to maintain stability on the rotating block 71, thereby reducing the difficulty of operation.

[0040] A connecting groove 84, which communicates with the first limiting groove 81, is provided on the side wall of the rotating block 71. A fixing rope 85 is disposed in the connecting groove 84 to block the sliding rod 82. The fixing rope 85 reduces the probability of the sliding rod 82 separating from the first limiting groove 81, thereby improving the stability of the device.

[0041] To reduce the difficulty for staff to move the sliding bar 82, a handle 9 is fixed to the end of the sliding bar 82.

[0042] The operating principle of a building ceiling in this embodiment is as follows: When the worker needs to install the base plate 21, the worker needs to fix the support frame 11 and the connecting column 1 together, and make the upper end of the connecting column 1 press against the inner ceiling wall of the building. Further, the worker can fix the support frame 11 to the ceiling using bolts, thus stabilizing the connecting column 1. Then, the worker only needs to support the base plate 21 and move it upwards to connect the mounting block 2 and the sliding groove 3, thus initially stabilizing the base plate 21 under the action of the fixing component 6. Further, the worker only needs to connect the fixing bolts 5 to the fixing plate 41 to fix the connecting column 1 and the base plate 21 together. In this process, a single person can complete the installation of the base plate 21; the operation is simple and the risk is low.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. 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.
