This kind of inspection opening has limitations, the size of the inspection opening is limited, which affects the maintenance operation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an installation structure of a ceiling board and a disassembly and assembly method for the last ceiling board to solve the problem of the limitations of the inspection opening in the small-space bathroom ceiling of the prior art.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The ceiling board installation structure of the present invention includes wall boards connected to the wall. A wall-top connection member is installed at the top of each wall board. The wall-top connection members are sequentially butted to form the overall framework of the ceiling. A C-shaped keel is installed at the top of each ceiling board, and the ceiling board is installed on the overall framework through the C-shaped keel at the top. The ceiling boards are sequentially butted to form the entire ceiling. Among them, corner codes are provided for the first ceiling board to the penultimate ceiling board. The corner codes connect the C-shaped keel at the top of the ceiling board and the wall. Limit blocks are installed above both sides of the wall corresponding to the area of the last ceiling board.

[0005] Further, the limit block includes a wall connection end perpendicular to the horizontal plane and a limit end provided at the top of the wall connection end. The limit end is parallel to the horizontal plane. The wall connection end and the limit end form a right angle, and the wall connection end and the limit end are integrally provided. The wall connection end is fixed on the wall, and the upper surface of the limit end serves as the support surface for the last ceiling board when installing the penultimate ceiling board.

[0006] Further, the thickness of the wall connection end and the limit end is 1-2 CM.

[0007] Further, the limiting block is made of wood, and the wall connection end of the wood is fixed to the wall with nail guns; alternatively, the limiting block is made of metal. For the metal limiting block, holes are drilled in the wall connection end, corresponding holes are drilled in the wall, expansion tubes are provided in the holes, and the metal limiting block is fixed to the wall by screwing the screws through the holes in the wall connection end and connecting to the expansion tubes.

[0008] Further, the wall top connection member is clamped on the top of the wall panel. The wall top connection member is provided with a stepped platform facing the inner side of the wall panel. The surface of the stepped platform is lower than the top surface of the wall top connection member. The two ends of the channel-shaped keel extend outward towards the two ends of the suspended ceiling board to form outer lapping ends. There are notches at the lower edges of the outer lapping ends, which are in fitting connection with the wall top connection member. The upper edges of the notches are lapped on the top surface of the wall top connection member, and the suspended ceiling board installed below the channel-shaped keel is in contact connection with the stepped platform of the wall top connection member.

[0009] Further, one end of the angle code is connected to the channel-shaped keel by bolts, and the other end is connected to the wall by self-tapping screws. The angle code is made of aluminum alloy.

[0010] Further, at least two channel-shaped keels are provided on each suspended ceiling board. The channel-shaped keels are parallel to each other and arranged at intervals, and the channel-shaped keels are connected to the suspended ceiling board by screws.

[0011] Even further, reinforcement members are provided between the channel-shaped keel and the suspended ceiling board. There are multiple reinforcement members, which are distributed at intervals along the channel-shaped keel.

[0012] Even further, the reinforcement member includes a horizontal main body part. There are limiting parts on both sides above the horizontal main body part. The limiting parts are connected to the horizontal main body part, and a chute is formed between the limiting parts and the horizontal main body part. The two sides of the bottom of the channel-shaped keel are provided with outer edge parts extending horizontally outward. The reinforcement member is clamped on the two outer edge parts of the channel-shaped keel through the two limiting parts, and can be slid to an appropriate position through the chute, and then the channel-shaped keel, the reinforcement member, and the suspended ceiling board are connected by screws.

[0013] The disassembly and assembly method of the last suspended ceiling board includes the following installation steps:

[0014] Step 1, install limiting blocks on both side walls of the area corresponding to the last suspended ceiling board;

[0015] Step 2: Lift the last suspended ceiling board and the second last suspended ceiling board upwards simultaneously. The last suspended ceiling board needs to be lifted above the limiting block, and the second last suspended ceiling board is lapped on the wall top connection member;

[0016] Step 3: After the second last suspended ceiling board is installed, displace the channel-shaped keel above the last suspended ceiling board from the limiting block, and sink it below the side of the limiting block, and then slide it into directly below the limiting block to complete the installation of the last suspended ceiling board;

[0017] The disassembly steps are as follows:

[0018] Lift the last ceiling board and slide it to the side of the limit block, then lift it until the channel-shaped keel is higher than the limit block, and then translate it to directly above the limit block, and place the last ceiling board above the limit block.

[0019] Beneficial effects:

[0020] The present invention adopts a lapping method, with both ends of the ceiling board lapped on the wall-top connecting member. The last ceiling board has the functions of quick installation and disassembly, can be used as an inspection opening, and is convenient for inspection;

[0021] The first ceiling board to the penultimate ceiling board of the present invention are all equipped with angle codes. The angle codes connect the channel-shaped keel at the top of the ceiling board and the wall. When the overall space bathroom door is opened quickly, the ceiling board will be subjected to negative pressure. After the angle codes connect the channel-shaped keel at the top of the ceiling board and the wall, they can resist the negative pressure effect; while the last ceiling board of the present invention is not equipped with an angle code. Considering that there is no operating space for installing the angle code after the last ceiling board is installed, the last ceiling board cannot be fixed by the angle code method. And the last ceiling board needs to achieve the function of disassembly and replacement. Therefore, the last ceiling board is equipped with limit blocks. The limit blocks are installed on both sides of the wall in the corresponding area of the last ceiling board. When installing the last ceiling board, the last ceiling board and the penultimate ceiling board need to be lifted up simultaneously. The last ceiling board needs to be lifted above the limit block. After the penultimate ceiling board is installed, the keel is misaligned and sunk below the side of the limit block, and then slides into directly below the limit block to complete the installation of the last ceiling board; during disassembly, perform the steps in the reverse order of installation, and the last board can be easily disassembled and replaced. At the same time, the limit block can also play a role in resisting negative pressure and lifting. Description of the drawings

Detailed implementation manners

[0027] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are generally only some embodiments of the present invention, rather than all embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention shall fall within the protection scope of the present invention.

[0028] Refer to Figures 1 to 4 , an installation structure of a ceiling board, including a wall panel 1 connected to a wall. A wall top connecting member 2 is installed at the top of each wall panel 1. The wall top connecting members 2 are butt-jointed in sequence to form the overall framework of the ceiling. A channel-shaped keel 4 is installed at the top of each ceiling board 3 to achieve the function of anti-deformation. The ceiling board 3 is installed on the overall framework through the channel-shaped keel 4 at the top. The ceiling boards 3 are butt-jointed in sequence to form the entire ceiling. Among them, the first to the penultimate ceiling boards 3 are all equipped with angle brackets 5. The angle brackets 5 connect the channel-shaped keel 4 at the top of the ceiling board 3 and the wall, playing a role in resisting negative pressure and lifting. The last ceiling board 3 is not equipped with an angle bracket 5. It is considered that after the last ceiling board 3 is installed, there is no operating space for installing the angle bracket 5, and the last ceiling board 3 cannot be fixed by the angle bracket 5. Moreover, the last ceiling board 3 needs to achieve the function of disassembly and replacement. Therefore, the last ceiling board 3 is equipped with a limiting block 6. The limiting block 6 is pre-installed on both sides of the wall corresponding to the area of the last ceiling board 3. When installing the last ceiling board 3, the last ceiling board 3 and the penultimate ceiling board 3 need to be lifted up simultaneously. The last ceiling board 3 needs to be lifted above the limiting block 6. After the penultimate ceiling board 3 is installed, the keel is misaligned and sunk below the side of the limiting block 6, and then slides into the position directly below the limiting block 6 to complete the installation of the last ceiling board 3. During disassembly, perform the steps in the reverse order of the installation steps, and the last board can be easily disassembled and replaced. At the same time, the limiting block 6 can play a role in resisting negative pressure and lifting.

[0029] As a preferred embodiment, when installing the penultimate ceiling board 3, the last ceiling board 3 needs to be lifted above the limit block 6. The limit block 6 needs to maintain stability as a support. The limit block 6 includes a wall connection end 61 perpendicular to the horizontal plane and a limit end 62 provided at the top of the wall connection end 61. The limit end 62 is parallel to the horizontal plane. The wall connection end 61 and the limit end 62 form a right angle, and the wall connection end 61 and the limit end 62 are integrally provided. The wall connection end 61 is fixed to the wall, and the upper surface of the limit end 62 serves as the support surface for the last ceiling board 3 when installing the penultimate ceiling board 3. The wall connection end 61 and the limit end 62 set at a right angle are more stable when supporting.

[0030] As a further preferred embodiment, considering that the limit block 6 needs to maintain stability as a support, the wall connection end 61 and the limit end 62 should have a certain thickness, and the thickness range is 1-2 cm. The limit block 6 can be made of wood. In the case of wood, the wall connection end 61 is fixed to the wall with a nail gun; or it can be made of metal. In the case of metal, holes need to be pre-drilled in the wall connection end 61, drill holes in the wall, put an expansion tube in the hole in the wall, and pass a screw through the hole in the wall connection end and connect it to the expansion tube to fix the limit block 6 to the wall.

[0031] As a preferred embodiment, the wall-top connection member 2 is clamped on the top of the wall panel 1. The wall-top connection member 2 is provided with a stepped platform 21 facing the inner side of the wall panel 1. The surface of the stepped platform 21 is lower than the top surface of the wall-top connection member 2. The two ends of the channel-shaped keel 4 extend towards the outside of the two ends of the ceiling board 3 to form outer lapping ends 41. There is a notch 42 at the lower edge of the outer lapping end 41. The notch 42 is in mating connection with the wall-top connection member 2. The upper edge of the notch 42 is placed on the top surface of the wall-top connection member 2. The ceiling board 3 installed below the channel-shaped keel 4 is in contact connection with the stepped platform 21 of the wall-top connection member 2. The function of the stepped platform 21 is to trim the edge of the ceiling board 3. At the same time, the stepped platform 21 can also serve as the support for the ceiling board 3, which can further enhance the stability of the structure.

[0032] As a preferred embodiment, the corner bracket 5 used to connect the channel-shaped keel 4 and the wall is bolted to the channel-shaped keel 4 at one end and screwed to the wall with self-tapping screws at the other end. The corner bracket 5 can be made of a relatively soft aluminum alloy material.

[0033] As a preferred embodiment, the U-shaped keel 4, as a component for preventing the ceiling board 3 from deforming and connecting the wall-top connecting member 2, is provided with at least two on each ceiling board 3. The two U-shaped keels 4 are parallel to each other and arranged at intervals, and the U-shaped keel 4 is connected to the ceiling board 3 by screws. It is most convenient to directly connect the U-shaped keel 4 and the ceiling board 3 with screws. However, in addition, a reinforcing member 7 can be provided between the U-shaped keel 4 and the ceiling board 3 to improve the nail-holding force of the screws; there are multiple reinforcing members 7, which are distributed at intervals along the U-shaped keel 4.

[0034] As a preferred embodiment, the reinforcing member 7 includes a horizontal main body portion 71. There are limiting portions 72 on both sides above the horizontal main body portion 71. The limiting portions 72 are connected to the horizontal main body portion 71, and a chute is formed between the limiting portions 72 and the horizontal main body portion 71. Both sides of the bottom of the U-shaped keel 4 are provided with outwardly extending horizontal edge portions 43. The reinforcing member 7 is stuck on the two edge portions 43 of the U-shaped keel 4 through the two limiting portions 72, and can slide to an appropriate position through the chute, and then the U-shaped keel 4, the reinforcing member 7, and the ceiling board 3 are connected by screws.

[0035] The disassembly and assembly method of the last ceiling board in this embodiment includes the following installation steps:

[0036] Step 1: Install the limiting blocks 6 on the two side walls of the area corresponding to the last ceiling board 3.

[0037] Step 2: Lift the last ceiling board 3 and the second-to-last ceiling board 3 up to the top at the same time. The last ceiling board 3 needs to be lifted above the limiting block 6, and the second-to-last ceiling board 3 is lapped on the wall-top connecting member 2.

[0038] Step 3: After the second-to-last ceiling board 3 is installed, displace the U-shaped keel 4 above the last ceiling board 3 from the limiting block 6, and sink it below the side of the limiting block 6, and then slide it into directly below the limiting block 6 to complete the installation of the last ceiling board 3.

[0039] The disassembly steps are as follows:

[0040] Lift the last ceiling board 3 and slide it to the side of the limiting block 6, and then lift it until the U-shaped keel 4 is higher than the limiting block 6 and then translate it to directly above the limiting block 6, and place the last ceiling board 3 above the limiting block 6.
