Description

Technical Field

[0001] This application relates to the field of ceiling construction technology, and in particular to a prefabricated ceiling panel installation structure and installation method. Background Technology

[0002] A suspended ceiling refers to a type of decoration applied to the top of a living space. Simply put, it refers to the decoration of the ceiling and is an important part of interior decoration. Suspended ceilings serve functions such as heat insulation, sound insulation, and sound absorption, and also conceal electrical, ventilation, air conditioning, communication, fire protection, and alarm piping and equipment.

[0003] Regarding the aforementioned technologies, currently, ceiling installation requires drilling holes in the on-site structure to install expansion bolts, which to some extent damages the on-site structure. Summary of the Invention

[0004] To reduce damage to the wall structure during ceiling installation, this application provides a prefabricated ceiling panel installation structure and installation method.

[0005] The prefabricated ceiling panel installation structure provided in this application adopts the following technical solution:

[0006] A prefabricated ceiling panel installation structure includes several threaded sleeves, which are embedded in a ceiling plate. Each threaded sleeve is threadedly connected to a hanger rod. The hanger rods are divided into several groups, and each group of hanger rods is connected to a keel. The keels are divided into several groups, and each group of keels is connected to a ceiling panel. Adjacent ceiling panels are connected by self-locking components, and the ceiling panels are provided with clamping components for positioning.

[0007] By adopting the above technical solution, the keel and ceiling panel are first suspended by the hangers, and then the clamping parts are adjusted to make the ceiling panel firmly supported between the two side walls, limiting the swing of the ceiling panel. Then another ceiling panel is suspended, and the adjacent ceiling panels are spliced ​​together by the self-locking parts. By repeating the operation in sequence, the ceiling construction is completed. Compared with the traditional ceiling construction, there is no need to drill holes in the original wall structure, reducing damage to the wall structure. At the same time, by loosening the self-locking parts and clamping parts and separating the hangers from the keel, the ceiling panel can be quickly disassembled, which is convenient for replacement and maintenance.

[0008] Optionally, the self-locking component includes a first cylindrical block and a second cylindrical block, each located on one side of the ceiling panel. The second cylindrical block is rotatably connected to the ceiling panel. The first cylindrical block corresponds to the second cylindrical block of an adjacent ceiling panel. The first cylindrical block has at least two first locking blocks, and the second cylindrical block has at least two second locking blocks. The first locking blocks have a first locking groove on the side facing away from the adjacent ceiling panel, and the second locking blocks have a groove on the side facing away from the adjacent ceiling panel. A second locking slot is provided. At least two first locking blocks are provided on the first cylindrical block. The first locking blocks correspond one-to-one with the second locking blocks. A second locking block is provided on the second cylindrical block. The second locking blocks correspond one-to-one with the first locking blocks. Two adjacent ceiling panels are aligned and spliced. The corresponding first cylindrical blocks and second cylindrical blocks are interlocked with each other. By rotating the second cylindrical block, the second locking block is locked into the corresponding first locking slot. At the same time, the first locking block is locked into the corresponding second locking slot to form a self-locking mechanism.

[0009] By adopting the above technical solution, adjacent ceiling panels are aligned and spliced, so that the first cylindrical block and the corresponding second cylindrical block are engaged. When the second cylindrical block is rotated, the second cylindrical block drives the second locking block to engage in the corresponding first locking groove, and the first locking block engages in the corresponding second locking groove, thus quickly forming a self-locking mechanism between adjacent ceiling panels, strengthening the connection between adjacent ceiling panels and reducing the seams between ceiling panels.

[0010] Optionally, there are several of the first cylindrical blocks and the second cylindrical blocks arranged along the length of the ceiling panel. The second cylindrical block is coaxially fixed with a gear sleeve. The ceiling panel is slidably connected with a rack. The rack of one ceiling panel meshes with all the gear sleeves of the ceiling panel simultaneously.

[0011] By adopting the above technical solution, the rack is moved, and the rack drives the gear sleeve to rotate, so that several second cylindrical blocks rotate simultaneously and form a self-locking with the corresponding first cylindrical blocks, which facilitates installation. Furthermore, the cooperation of multiple first cylindrical blocks and second cylindrical blocks further strengthens the connection between adjacent ceiling panels.

[0012] Optionally, the ceiling panel has a fixing hole, and the rack is threaded with a fixing bolt. When the first cylindrical block and the second cylindrical block are in a self-locking state, the fixing bolt is aligned and can be inserted into the fixing hole.

[0013] By adopting the above technical solution, when the first cylindrical block and the second cylindrical block are interlocked, the fixing bolt of the rack is aligned with the fixing hole. Rotating the fixing bolt allows it to be inserted into the fixing hole, thereby restricting the movement of the rack and preventing the first cylindrical block and the second cylindrical block from separating from each other.

[0014] Optionally, both sides of the ceiling panel are provided with abutment plates, the abutment plates are flush with the side of the ceiling panel facing away from the ceiling panel, and the side of the abutment plate facing away from the ceiling panel is provided with an elastic pad along its length.

[0015] By adopting the above technical solution, the elastic pad can prevent the ceiling panel from being crushed and damaged due to the deviation in specifications of the first and second cylindrical blocks during self-locking. This strengthens the protection of the ceiling panel. At the same time, after the two ceiling panels are spliced ​​together, the two elastic pads press against each other, further reducing the gaps between the ceiling panels.

[0016] Optionally, a hook is provided on the keel, the hook is connected to a fixed rod, the fixed rod is threadedly connected to a rotating sleeve, and the end of the rotating sleeve away from the fixed rod is threadedly connected to the hook rod.

[0017] By adopting the above technical solution, the rotating sleeve is rotated to lift it. The fixed rod is then threadedly connected to the rotating sleeve. The positions of the fixed rod and the rotating sleeve are adjusted, and the hook is then hung on the fixed rod to complete the suspension of the keel. This also makes it easy to control the suspension height of the keel.

[0018] Optionally, the clamping component includes a push rod, which is slidably connected to the side of the ceiling panel facing the ceiling. The push rod moves along the width direction of the ceiling panel. The push rod is slidably provided with an abutment rod. An abutment joint is provided at the end of the abutment rod facing the wall. An abutment joint is connected to an abutment spring. The abutment spring is connected to the end of the push rod facing the wall. A first connecting block is rotatably connected to the push rod. A second connecting block is rotatably connected to the ceiling panel. The first connecting block and the second connecting block are hinged. The hinge point between the first connecting block and the push rod, the hinge point between the second connecting block and the ceiling panel, and the central axis of the push rod are all located on the same horizontal plane. A lever is connected to the first connecting block. When the abutment joint is fully pressed against the wall, the hinge point between the first connecting block and the second connecting block is located on the same horizontal plane as the central axis of the push rod.

[0019] By adopting the above technical solution, rotating the lever causes the first connecting block and the second connecting block to rotate. The first connecting block pushes the push rod to move closer to the wall. The movement of the push rod causes the abutment to press against the wall. As the push rod continues to move, the abutment rod gradually extends into the push rod, and the abutment spring is in a compressed state. Continuing to rotate the push rod makes the hinge points of the first connecting block and the push rod, the hinge points of the second connecting block and the ceiling panel, the central axis of the push rod, and the hinge points of the first and second connecting blocks all lie on the same horizontal plane. Since the reaction force of the abutment spring is on the same horizontal plane as the central axis, the reaction force of the abutment spring cannot push the first and second connecting blocks to rotate. This allows the push rod to remain stationary, and the abutment spring can constantly apply pressure to the abutment, keeping the abutment in a state of continuous pressure against the wall. This allows the ceiling panel to be tightly supported between the two side walls, achieving the positioning of the ceiling panel without drilling holes in the wall structure, reducing cracking and damage to the wall structure during ceiling installation, and improving the protection of the wall.

[0020] A method for installing prefabricated ceiling panels, using a prefabricated ceiling panel installation structure, employs the following technical solution: including the following steps:

[0021] S1. Threaded sleeve embedded in the top slab concrete;

[0022] S2. The keel and ceiling panel are assembled.

[0023] S3. Connect the keel to the threaded sleeve to complete the suspension of the keel and ceiling panel;

[0024] S4. Adjust the clamping parts to ensure the ceiling panel is securely supported between the two side walls;

[0025] S5. Suspend adjacent keel and ceiling panels;

[0026] S6. Join adjacent ceiling panels together and lock them in place with locking devices.

[0027] Optionally, in step S1, the opening of the threaded sleeve should be properly sealed to prevent concrete slurry from blocking it.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. First, suspend the keel and ceiling panel using the hangers. Then, adjust the clamps to hold the ceiling panel firmly between the two walls, limiting its sway. Next, suspend another ceiling panel and use self-locking devices to join adjacent panels. Repeat this process to complete the ceiling installation. Compared to traditional ceiling installation, this method eliminates the need to drill holes in the original wall structure, reducing damage. Loosening the self-locking devices and clamps and separating the hangers from the keel allows for quick removal of the ceiling panels, facilitating replacement and maintenance.

[0030] 2. Rotate the lever, which drives the first and second connecting blocks to rotate. The first connecting block pushes the push rod closer to the wall. The push rod's movement causes the abutment to press against the wall. As the push rod continues to move, the abutment gradually extends into the push rod, and the abutment spring is compressed. Continue to rotate the push rod until the hinge points of the first connecting block and the push rod, the second connecting block and the ceiling panel, the central axis of the push rod, and the hinge points of the first and second connecting blocks are all on the same horizontal plane. Since the reaction force of the abutment spring is on the same horizontal plane as the central axis, the reaction force of the abutment spring cannot push the first and second connecting blocks to rotate. This allows the push rod to remain stationary, and the abutment spring can constantly apply pressure to the abutment, keeping the abutment continuously pressed against the wall. This allows the ceiling panel to be tightly supported between the two side walls, achieving the positioning of the ceiling panel without drilling holes in the wall structure, reducing the risk of cracking and damage to the wall structure during ceiling installation, and improving the protection of the wall.

[0041] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0042] This application discloses a prefabricated ceiling panel installation structure.

[0043] like Figure 1 , Figure 2 and Figure 3 The prefabricated ceiling panel installation structure includes several keels 1, with each pair of keels 1 forming a group. Each group of keels 1 is bolted together with a ceiling panel 2. Each keel 1 has hooks 11 welded to both ends. Several threaded sleeves 3 are pre-embedded in the ceiling concrete, with each threaded sleeve 3 having its opening facing downwards. Each threaded sleeve 3 is threadedly connected to a hanger rod 31, and each hanger rod 31 is threadedly connected to a rotating sleeve 32. The end of the rotating sleeve 32 away from the hanger rod 31 is threadedly connected to a fixed rod 33. Each hook 11 corresponds to a fixed rod 33, and the hook 11 is hung on the corresponding fixed rod 33.

[0044] like Figure 4 Several clamping parts 5 are provided on both sides of the ceiling panel 2 near the side wall for positioning. Abutment plates 21 are fixed on both sides of the ceiling panel 2. An elastic pad 22 is provided on the side of the abutment plate 21 facing the adjacent ceiling panel 2. Two adjacent ceiling panels 2 are spliced ​​together and the adjacent elastic pads 22 are pressed against each other. The adjacent ceiling panels 2 are connected by a self-locking part 4, which is located above the abutment plate 21.

[0045] When installing the suspended panel, first connect the threaded rod 31 to the threaded sleeve 3, then connect the rotating sleeve 32 to the end of the rod 31 away from the threaded sleeve 3, and then connect the fixed rod 33 to the end of the rotating sleeve 32 away from the rod 31. Rotate the rotating sleeve 32 to raise it. Then connect the fixed rod 33 to the rotating sleeve 32. Rotate the fixed rod 33 to adjust the position of the fixed rod 33 and the rotating sleeve 32. Finally, hang the hook 11 on the fixed rod 33 to complete the suspension of the keel 1 and the ceiling panel 2, and facilitate the control of the suspension height of the keel 1 and the ceiling panel 2.

[0046] After the keel 1 and ceiling panel 2 are suspended, adjust the clamping parts 5 at both ends of the ceiling panel 2 to ensure that the ceiling panel 2 is firmly supported between the two side walls, and use the fixing rod 33 to limit the displacement of the ceiling panel 2. Then suspend adjacent keels 1 and ceiling panels 2, and use self-locking parts 4 to splice adjacent ceiling panels 2. Then adjust the clamping parts 5 of the newly installed ceiling panel 2 for positioning. Repeat the above operation to complete the installation of all ceiling panels 2.

[0047] Compared to traditional ceiling construction, there is no need to drill holes in the original wall structure, reducing damage to the wall structure. Furthermore, by loosening the self-locking part 4 and the clamping part 5, and then separating the fixing rod 33 from the hook 11, the ceiling panel can be quickly disassembled, facilitating replacement and maintenance.

[0048] like Figure 5 , Figure 6 and Figure 7 The self-locking component 4 includes a plurality of first cylindrical blocks 41 and a plurality of second cylindrical blocks 42. The first cylindrical blocks 41 and the second cylindrical blocks 42 are each located on one side of the ceiling panel 2, and the plurality of first cylindrical blocks 41 and the plurality of second cylindrical blocks 42 are equidistantly arranged along the width direction of the ceiling panel 2. The second cylindrical blocks 42 are rotatably connected to the ceiling panel 2, and a gear sleeve 43 is coaxially fixed to the end of the second cylindrical block 42 that extends into the ceiling panel 2.

[0049] like Figure 8 A rack 44 is slidably connected to the side of the ceiling panel 2 facing the ceiling, and the rack 44 meshes with all the gear sleeves 43 of the same ceiling panel 2 at the same time;

[0050] like Figure 5 , Figure 6 and Figure 7 The first cylindrical block 41 corresponds one-to-one with the second cylindrical block 42 of the adjacent ceiling panel 2. The first cylindrical block 41 has two first snap-fit ​​blocks 45 welded at equal intervals along its circumference. The second cylindrical block 42 has two second snap-fit ​​blocks 46 welded at equal intervals along its circumference. The first snap-fit ​​block 45 has a first snap-fit ​​groove 451 on the side away from the adjacent ceiling panel 2. The first snap-fit ​​groove 451 extends from both sides of the first snap-fit ​​block 45. The second snap-fit ​​block 46 has a second snap-fit ​​groove 461 on the side away from the adjacent ceiling panel 2. The second snap-fit ​​groove 461 extends from both sides of the second snap-fit ​​block 46.

[0051] Two first locking blocks 47 are welded on the first cylindrical block 41. The two first locking blocks 47 are arranged at equal intervals along the circumference of the first cylindrical block 41, and the first locking blocks 47 correspond one-to-one with the first locking blocks 45. The corresponding first locking blocks 47 and first locking blocks 45 are close to each other.

[0052] Two second locking blocks 48 are welded on the second cylindrical block 42. The two second locking blocks 48 are arranged at equal intervals along the circumference of the second cylindrical block 42, and the second locking blocks 48 correspond one-to-one with the second locking blocks 46. The corresponding second locking blocks 48 and the second locking blocks 46 are close to each other.

[0053] The first locking block 47 of the ceiling panel 2 corresponds one-to-one with the second locking block 46 of the adjacent ceiling panel 2, and the second locking block 48 of the ceiling panel 2 corresponds one-to-one with the first locking block 45 of the adjacent ceiling panel 2. The two adjacent ceiling panels 2 are aligned and spliced, and the corresponding first cylindrical block 41 and second cylindrical block 42 are interlocked with each other.

[0054] By rotating the second cylindrical block 42, the second locking block 48 is engaged in the corresponding first locking groove 451, and at the same time, the first locking block 47 is engaged in the corresponding second locking groove 461 to form a self-locking mechanism.

[0055] like Figure 9 The ceiling panel 2 has a fixing hole 23, and the rack 44 is threaded with a fixing bolt 441. When the first cylindrical block 41 and the second cylindrical block 42 are in a self-locking state, the fixing bolt 441 is aligned and can be inserted into the fixing hole 23.

[0056] Align and splice adjacent ceiling panels 2 so that the first cylindrical block 41 and the corresponding second cylindrical block 42 engage. Push the rack 44, which drives several gear sleeves 43 to rotate, thereby causing the second cylindrical block 42 to rotate. The second cylindrical block 42 drives the second locking block 48 to engage in the corresponding first locking groove 451, and the first locking block 47 to engage in the corresponding second locking groove 461, quickly forming a self-locking mechanism between adjacent ceiling panels 2, strengthening the connection between adjacent ceiling panels 2 and reducing the seams between ceiling panels 2.

[0057] When the first cylindrical block 41 and the corresponding second cylindrical block 42 are self-locked, the fixing bolt 441 of the rack 44 is aligned with the fixing hole 23. The fixing bolt 441 is rotated to insert it into the fixing hole 23, thereby restricting the movement of the rack 44 and preventing the first cylindrical block 41 and the second cylindrical block 42 from separating from each other.

[0058] like Figure 2 and Figure 3The clamping component 5 includes a push rod 51, which is slidably connected to the top surface of the ceiling panel 2. The push rod 51 is located at the end of the ceiling panel 2 and moves along the direction away from or towards the side wall. A clamping rod 52 is coaxially sleeved on the push rod 51. A clamping head 53 is fixed to the end of the clamping rod 52 facing the wall. A clamping spring 54 is connected to the end of the clamping head 53 facing away from the wall. The clamping spring 54 is connected to the end of the push rod 51 facing the wall. A first connecting block 55 is rotatably connected to the end of the push rod 51 away from the wall. The ceiling panel 2 is rotatably connected to... There is a second connecting block 56, and the first connecting block 55 is hinged to the second connecting block 56. The hinge point of the first connecting block 55 and the push rod 51, the hinge point of the second connecting block 56 and the ceiling panel 2, and the central axis of the push rod 51 are all located on the same horizontal plane. The first connecting block 55 is fixedly connected to a lever 57, which is located at the hinged end of the first connecting block 55 and the second connecting block 56. When the abutment 53 is fully pressed against the wall, the hinge point of the first connecting block 55 and the second connecting block 56, and the central axis of the push rod 51 are all located on the same horizontal plane.

[0059] Rotating lever 57 causes the first connecting block 55 and the second connecting block 56 to rotate. The first connecting block 55 pushes the push rod 51 closer to the wall. The movement of the push rod 51 causes the abutment 53 to press against the wall. As the push rod 51 continues to move, the abutment rod 52 gradually extends into the push rod 51, and the abutment spring 54 is compressed. Continuing to rotate the push rod 51 ensures that the hinge points of the first connecting block 55 and the push rod 51, the hinge points of the second connecting block 56 and the ceiling panel 2, the central axis of the push rod 51, and the hinge points of the first connecting block 55 and the second connecting block 56 are aligned. On the horizontal plane, since the direction of the reaction force of the abutment spring 54 is on the same horizontal plane as the central axis, the reaction force of the abutment spring 54 cannot push the first connecting block 55 and the second connecting block 56 to rotate. As a result, the push rod 51 can remain stationary, and the abutment spring 54 can constantly apply pressure to the abutment joint 53, so that the abutment joint 53 is in a state of continuous pressure against the wall. This allows the ceiling panel 2 to be tightly supported between the two side walls, thus achieving the positioning of the ceiling panel 2. Furthermore, there is no need to drill holes in the wall structure, reducing the risk of cracking and damage to the wall structure during ceiling installation and improving the protection of the wall.

[0060] The implementation principle of this application embodiment is as follows: the hook 11 is hung on the fixed rod 33 to complete the suspension of the keel 1 and the ceiling panel 2. Then, the lever 57 is rotated to make the abutment 53 press tightly against the wall, thereby making the ceiling panel 2 support tightly between the two side walls, restricting the swing of the ceiling panel 2. Then, another ceiling panel 2 is suspended, and the rack 44 is pushed to make the first locking block 45 and the second locking block 46 of the adjacent ceiling panels 2 interlock and self-lock, completing the splicing of the adjacent ceiling panels 2. By repeating the operation in sequence, the ceiling construction is completed. Compared with the traditional ceiling construction, there is no need to drill holes in the original wall structure, reducing damage to the wall structure. At the same time, the self-locking part 4 and the abutment 5 are released, and the hanging rod 31 is separated from the keel 1, so that the ceiling panel can be quickly disassembled, which is convenient for replacement and maintenance.

[0061] This application also discloses a method for installing prefabricated ceiling panels, which uses the prefabricated ceiling panel installation structure of this application for installation, and includes the following steps:

[0062] S1, Threaded sleeve 3 embedded in the top slab concrete;

[0063] Before pouring the concrete top slab, the threaded sleeve 3 is welded to the longitudinal reinforcement of the top slab, and the opening of the threaded sleeve 3 is plugged with a cap to prevent the mud from blocking the opening of the threaded sleeve 3 when pouring concrete.

[0064] S2. Assemble the keel 1 and ceiling panel 2.

[0065] The keel 1 and the ceiling panel 2 are first connected indoors with bolts. Before installing the keel 1, it is necessary to draw lines on the ceiling panel 2 for positioning to avoid the keel 1 being installed off-center.

[0066] S3. Connect the keel 1 to the threaded sleeve 3 to complete the suspension of the keel 1 and the ceiling panel 2;

[0067] Connect the hanger rod 31 to the threaded sleeve 3, then connect the rotating sleeve 32 to the hanger rod 31, and then connect the fixed rod 33 to the rotating sleeve 32. After adjusting the height of all the fixed rods 33, hang the hook of the keel 1 on the fixed rod 33.

[0068] S4. Adjust the clamping part 5 to make the ceiling panel 2 tightly supported between the two side walls;

[0069] The clamping parts 5 in the same row of the ceiling panels 2 need to be adjusted simultaneously;

[0070] S5. Suspend adjacent keel 1 and ceiling panel 2;

[0071] S6. Join the adjacent ceiling panels 2 together and lock them in place with locking devices;

[0072] After the adjacent ceiling panels 2 are spliced ​​and locked, the clamping parts 5 of the subsequently installed ceiling panels 2 are adjusted to position and fix the subsequently installed ceiling panels 2.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
