Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated suspended ceilings, and particularly to a disassembly and assembly mechanism for a prefabricated suspended ceiling and a method for using the same. Background Art

[0002] Traditional suspended ceiling systems mainly consist of double-layer keels, with relatively high installation costs, being relatively complex, time-consuming and laborious, and having relatively high requirements for the skills of workers. Moreover, traditional construction such as applying latex paint and putty causes serious environmental pollution, with high noise and a lot of dust, and the components cannot be reused, resulting in serious waste of resources. With the advancement of factory production and modular installation in the field of building decoration, the current prefabricated suspended ceiling technology has gradually matured. Currently, there are problems with insufficient service life, complex installation, uneven ceiling panels after installation, low installation efficiency, and complex disassembly in prefabricated suspended ceilings. In particular, for the installation between the last closing ceiling panel and the side wall, there are problems of inconvenient installation and disassembly.

[0003] The patent document with the publication number CN113216497A discloses such a hanging part ceiling structure and installation method, which relates to the technical field of decoration design. A hanging part ceiling structure includes a rotating part, a base connected to the rotating part, a wall hanging part for connecting the wall and the rotating part, a keel connected to the base, a ceiling panel arranged below the keel, and a connecting part for connecting the ceiling panel. The rotating part includes a rotating plate, a limiting plate arranged on the rotating plate, and a hinge for connecting the rotating plate and the base. The base includes a fixing plate connected to the hinge, side plates arranged on both sides of the fixing plate, and a bottom plate arranged below the fixing plate. The connecting part includes an embedding plate A arranged at the end of the ceiling panel and an embedding plate B connected to the embedding plate A at the end of the ceiling panel.

[0004] In this application, the articulated structure formed by the rotating part and the base is used to connect the wall hanging part on the side wall and the keel on the ceiling. However, it only considers the convenience of installation and does not consider the convenience of disassembly. The reason is that in its articulated structure, based on the setting of the limiting plate, its maximum opening angle is only 90°, and the rotating part can only rotate downward to be close to the base. Since after installation, the card slot formed between the rotating part and the ceiling panel just engages with the wall hanging part, during disassembly, the rotating part cannot rotate upward, that is, the width of the card slot in the vertical direction cannot be enlarged. Therefore, it is impossible to make the card slot fall off the wall hanging part by rotating the ceiling panel, and it can only be made to fall off the wall hanging part by horizontal translation. However, the other end of the ceiling panel is usually blocked by other ceiling panels, making it almost impossible for the ceiling panel to move horizontally, which causes problems with its disassembly. Summary of the Invention

[0005] The present invention aims to solve the above problems and provides a disassembly and assembly mechanism for a prefabricated suspended ceiling and a method for using the same.

[0006] The technical solution for the present invention to solve the problem is to first provide a disassembly and assembly mechanism for an assembled ceiling, which is used for the assembly and disassembly between a side wall and a ceiling closing plate. It includes a fixing member provided on the side wall and a rotating member provided on the ceiling closing plate. The rotating member includes a connecting plate connected to the ceiling closing plate and a movable part provided on the connecting plate. The fixing member includes a fixing plate connected to the side wall and a groove provided on the fixing plate. The groove wall of the groove includes a receiving part; the movable part is arranged in the groove and overlaps on the receiving part, and the surface of the movable part for abutting against the receiving part is arc-shaped.

[0007] As a preference of the present invention, receiving plates are respectively provided at both ends of the fixing plate perpendicular to the horizontal plane, and the grooves are provided on both receiving plates, and both ends of the movable part are respectively arranged in the two grooves.

[0008] As a preference of the present invention, the connecting plate is clamped between the two receiving plates.

[0009] As a preference of the present invention, the top surface of the ceiling closing plate abuts against the bottom surface of the receiving plate.

[0010] As a preference of the present invention, the movable part is connected to the connecting plate through an inclined block, so that the fixing plate, the connecting plate and the inclined block form a triangular structure.

[0011] As a preference of the present invention, the groove width of the groove in the direction perpendicular to the side wall is greater than the radial width of the movable part.

[0012] As a preference of the present invention, a limiting block for preventing the movable part from falling off is provided at the notch of the groove.

[0013] As a preference of the present invention, a reinforcing spring is further included. One end of the reinforcing spring is connected to the fixing plate and the other end abuts against the movable part.

[0014] As a preference of the present invention, a contact block is provided at the end of the reinforcing spring that abuts against the movable part, and the surface of the contact block for abutting against the movable part is a concave arc surface that fits the outer surface of the movable part.

[0015] Another object of the present invention is to provide a usage method of the disassembly and assembly mechanism for an assembled ceiling, including the following steps:

[0016] During assembly: First, install the fixing member on the side wall and install the rotating member on the ceiling closing plate; then lift the ceiling closing plate in an inclined state and lift it above the plane where the fixing member and the ceiling plate are located; then insert the movable part into the groove; finally, rotate the ceiling closing plate around the movable part until it is flush with the ceiling plate;

[0017] During disassembly: First, rotate the ceiling closing plate around the movable part; then lift the ceiling closing plate so that the movable part is withdrawn from the groove.

[0018] Advantages of the present invention:

[0019] In this application, a detachable hinge is achieved through the groove and the movable part. On the one hand, the movable part is lapped in the groove. Based on the self-weight of the rotating part and the ceiling closing plate itself, the rotating part will not rotate by itself in the natural state, ensuring the installation stability. On the other hand, under the action of an external force, the movable part can rotate freely in the groove. Whether it is assembly or disassembly, the ceiling closing plate can enter and exit between the fixing part and the ceiling board in an inclined state, without being affected by the ceiling board beside the ceiling closing plate, ensuring the assembly convenience and disassembly convenience.

[0025] The following are the specific implementation manners of the present invention. In combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] A disassembly and assembly mechanism for an assembled ceiling, which is used for the assembly and disassembly between a side wall and a ceiling closing plate. Since the assembled ceiling structure starts from one side wall and the ceiling plates are successively lifted and installed, when installing the last ceiling plate, the last ceiling plate just closes the gap between the other side wall and the installed ceiling plates. Therefore, the last ceiling plate is called the ceiling closing plate. Since the ceiling closing plate needs to be clamped between the other side wall and the installed ceiling plates, and the width of this gap is basically the same as the width of the ceiling closing plate to ensure the integrity of the entire ceiling structure. Therefore, there is a problem that the assembly of the ceiling closing plate is inconvenient. At present, most of the ceiling closing plates are either directly connected to the keel or wood-plastic line of the side wall by screws, or installed through various installation structures, but the disassembly problem is not considered. This causes problems such as inconvenient disassembly during the maintenance of this part of the ceiling, damage to the ceiling closing plate during disassembly and inability to be reused. Based on this, this application provides this disassembly and assembly structure.

[0027] As Figure 1 and Figure 4 shown, the disassembly and assembly structure of this application includes a fixing member 1 arranged on the side wall and a rotating member 2 arranged on the ceiling closing plate. The fixing member 1 is hinged to the rotating member 2. Hinging refers to a connection method that restricts the movement between two objects but does not restrict the rotation between the two objects, so that the fixing member 1 and the rotating member 2 can rotate around the hinge part. In this application, the fixing member 1 is mainly set as fixed, and the rotating member 2 is movable and rotates around the hinge part. At this time, the ceiling closing plate connected to the rotating member 2 also rotates around the hinge part. When the ceiling closing plate rotates, its width in the horizontal direction can change. The larger the angle between its body and the horizontal plane, the smaller its width in the horizontal direction. By reducing the width of the ceiling closing plate in the horizontal direction, it is convenient for the ceiling closing plate to enter and exit the narrow gap between the side wall and the ceiling plate, so as to improve the convenience of installation and disassembly of the ceiling closing plate.

[0028] Generally, it is difficult to disassemble two hinged objects. Different from the hinge structure in the prior art, in order to enable the ceiling closing plate to be disassembled from the side wall in this application, a detachable hinge structure is designed.

[0029] Among them, the rotating member 2 includes a connecting plate 21 connected to the ceiling closing plate and a movable portion 22 provided on the connecting plate 21. The connecting plate 21 is preferably a flat plate parallel to the ceiling closing plate, and the connection strength is improved by increasing the connection area. The connection method between the connecting plate 21 and the ceiling closing plate is not limited, and it can be screw connection or a slot is opened on the side of the ceiling closing plate, and the connecting plate 21 is inserted into the slot. In this embodiment, the connecting plate 21 is directly superposed on the top surface of the ceiling closing plate and then screw-connected. The bottom surface of the movable portion 22 is arc-shaped for easy rotation, and it can be a fin-shaped metal sheet, a metal sheet with an arc-shaped cross-section, a rotating shaft, etc. In this embodiment, a rotating shaft is selected, and its axial direction is parallel to the horizontal direction and also parallel to the side wall. In order to prevent the connecting plate 21 and the ceiling closing plate from affecting the installation and rotation of the movable portion 22, the movable portion 22 and the connecting plate 21 are connected by a connecting block. The width of the connecting block along the axial direction of the movable portion 22 is smaller than the axial length of the movable portion 22 and the width of the connecting plate 21. The part of the movable portion 22 not connected to the connecting block may not be blocked. The connection point between the connecting block and the movable portion 22 is preferably set at the center point of the movable portion 22. The connecting block can form an arbitrary angle with the connecting plate 21. For example, the connecting block is perpendicular to the connecting plate 21. At this time, the load force directions of the connecting block and the movable portion 22 on the connecting plate 21 are the same, and the load strength is relatively high. Another example is that an acute angle is formed between the connecting block and the connecting plate 21. At this time, a triangle is formed among the movable portion 22, the connecting block, and the connecting plate 21. Combined with the subsequent connection with the fixing member 1 on the side wall, a stable triangular structure can be formed, which can improve the installation stability. In this embodiment, the two methods are combined, that is, the connecting block includes a vertical portion perpendicular to the connecting plate 21 and an inclined block 23 that forms an acute angle with the connecting plate 21.

[0030] The fixing member 1 includes a fixing plate 11 connected to the side wall and a groove 12 provided on the fixing plate 11. The fixing plate 11 is preferably a flat plate parallel to and connected to the side wall, and the connection strength is also improved by increasing the connection area. The fixing plate 11 and the side wall are preferably connected by a connection method with higher strength such as expansion screws. The groove wall of the groove 12 includes a receiving portion, such as Figure 2As shown, in this embodiment, the notch of the groove 12 faces upward, and the bottom of the groove 12 serves as the receiving portion. The groove 12 is used for the subsequent installation of the movable portion 22. Since a connecting block and a connecting plate 21 are connected to the center of the movable portion 22, in order to ensure the stability of the movable portion 22 after being installed on the fixing member 1, it is preferably to provide two grooves 12 to respectively receive the two ends of the movable portion 22. Therefore, in this embodiment, the two ends of the fixing plate 11 perpendicular to the horizontal plane are respectively provided with receiving plates 13. The receiving plates 13 are preferably perpendicular to the side wall. Grooves 12 are provided on the top surfaces of the two receiving plates 13. Based on this, when connecting the side wall and the ceiling closing plate, the two ends of the movable portion 22 are respectively arranged in the two grooves 12 and overlap on the receiving portions of the two grooves 12, and the connecting block is located between the two receiving plates 13. In order to further improve the connection stability between the fixing member 1 and the rotating member 2, by adjusting the width of the connecting plate 11 along the axial direction of the movable portion 22, the connecting plate 11 can be just clamped between the two receiving plates 13, and the connection strength is improved by the frictional force between the connecting plate 11 and the receiving plate 13. Further, by controlling the height of the connecting block, the top surface of the ceiling closing plate is controlled to abut against the bottom surface of the receiving plate 13. On the one hand, the fixing member 1 is covered, and on the other hand, when a connection error occurs at one end of the ceiling closing plate close to the ceiling board, the end close to the side wall is prevented from tilting up, so that the movable portion 22 falls off from the groove 12.

[0031] For the ceiling closing plate, one end is connected to the side wall through the rotating member 2, and the other end also needs to be connected to the ceiling board to ensure its stability. In the ceiling structure, the connection method between the ceiling boards is mostly: a card slot is provided on the side surface of the ceiling board, and the two ends of a connecting member are respectively inserted into the card slots of two adjacent ceiling boards, and the connecting member is connected to the ceiling keel. The connection between the ceiling closing plate and the ceiling board is also like this. Usually, the connecting member is installed first, and then the ceiling closing plate is installed. At this time, the width of the gap between the side wall and the connecting member available for the installation of the ceiling closing plate is further reduced. Based on this, in this embodiment, as Figure 2 shown, the width of the groove 12 is enlarged so that the groove width of the groove 12 in the direction perpendicular to the side wall is greater than the radial width of the movable portion 22, so that the movable portion 22 can move left and right in the groove 12. By moving the movable portion 22, it can help the card slot on the side surface of the ceiling closing plate to be inserted into and disassembled from the connecting member. At this time, a limiting block 121 for preventing the movable portion 22 from falling off during rotation can also be provided at the notch of the groove 12.

[0032] Further, in order to avoid the influence of the wider groove 12 on the stability of the ceiling closing plate after installation, as Figure 3As shown, it further includes a reinforcing spring 3. One end of the reinforcing spring 3 is connected to the fixed plate 11, and the other end abuts against the movable part 22, so as to abut against the movable part 22 through the reinforcing spring 3. In order to improve the abutting effect, an abutting block is provided at the end of the reinforcing spring 3 that abuts against the movable part 22. The surface of the abutting block for abutting against the movable part is a concave arc surface that fits the outer surface of the movable part 22.

[0033] The using method of the disassembly and assembly mechanism of the above prefabricated ceiling includes the following steps:

[0034] As Figure 4 shown, during assembly: First, calculate the number of disassembly and assembly mechanisms to be used according to the load-bearing requirements and the strength of the ceiling board; then install a number of fixing parts 1 on the side wall according to the quantity requirements, and install a number of rotating parts 2 on the ceiling closing plate; then as Figure 4 shown in the upper figure of Figure 4 lift the ceiling closing plate in an inclined state and lift it above the plane where the fixing part 1 and the ceiling board are located; then insert the movable part 22 into the groove 12; then as Figure 4 shown in the middle figure of

[0035] rotate the ceiling closing plate around the movable part 22 until it is flush with the ceiling board; finally as Figure 4 shown in the lower figure of Figure 4 horizontally move the ceiling closing plate so that the card slot on its side is inserted into the connecting part. Figure 4 During disassembly: Reverse the order of Figure 4 shown in the lower figure of
