[0001] The present invention relates to the technical field of ceiling installation, and particularly relates to an assembled splicing ceiling installation structure and an installation method thereof. Background Art

[0002] In the installation of existing ceiling panels, the keel is inserted into the hanging piece. The top end of the keel is connected to the wall top, and the bottom end of the hanging piece is connected to two adjacent ceiling panels, so as to lift and fix the ceiling panels. However, since there is no matching limiting structure between the hanging piece and the keel, the hanging piece is prone to shift in the horizontal direction, resulting in unstable installation of the keel and the hanging piece. At the same time, in the installation of existing ceiling panels, the bottom end of the hanging piece is connected to the long sides of two adjacent ceiling panels, and the short sides of two adjacent ceiling panels are not connected and fixed, so that the stability of the short sides of two adjacent ceiling panels is poor.

Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0030] Please refer to Figures 1 to 8 。For the assembled splicing ceiling installation structure according to the embodiment of the present invention, it includes a plurality of hanging members 2, a plurality of long-side connecting members 3, a plurality of short-side connecting members 4, and at least three panels 1. Two first insertion slots 11 are respectively provided on the two long sides of the panel 1; both side ends at the bottom of a long-side connecting member 3 are respectively inserted into the first insertion slots 11 of two adjacent panels 1. The bottom end of the hanging member 2 is connected to the top of the long-side connecting member 3, and the top end is connected to the wall ceiling. One end of the short-side connecting member 4 is connected to the panel 1, and the other ends of the two short-side connecting members 4 are connected to each other when the short sides of the two adjacent panels 1 corresponding to them are in mutual contact.

[0031] Here, the two first insertion slots 11 on the panel 1 are symmetrically arranged. The panel 1 is a square plate. Place two panels 1 along the X-axis direction, insert both side ends at the bottom of a long-side connecting member 3 into the first insertion slots 11 of two adjacent panels 1 respectively, and then place another panel 1 along the Y direction. That is, the two panels 1 in front are the No. 1 panel 1 and the No. 2 panel 1, and the panel 1 placed at this time is the No. 3 panel 1 arranged close to the No. 1 panel 1. Connect one end of each of the two short-side connecting members 4 to the No. 1 panel 1 and the No. 3 panel 1 respectively, and then push the No. 3 panel 1 towards the No. 1 panel 1 so that the short sides of the No. 1 panel 1 and the No. 3 panel 1 are in contact. At this time, the short-side connecting members 4 on the No. 1 panel 1 and the No. 3 panel 1 are in mutual contact. The bottom end of the hanging member 2 is connected to the top of the long-side connecting member 3, and the top end is connected to the wall ceiling, thereby lifting the panel 1. One end of the short-side connecting member 4 is connected to a position on the panel 1 close to the short side, and multiple short-side connecting members 4 can be connected to one panel 1.

[0032] The short-side connecting member 4 may include a mounting plate 41 and an abutting portion 43. At least two short-side connecting members 4 are connected to positions on two adjacent panels 1 close to the short sides. The mounting plates 41 of the two short-side connecting members 4 are respectively fixedly connected to the top ends of the two panels 1. There is an insertion gap 42 between the bottom ends of the abutting portions 43 of the two short-side connecting members 4 and the two panels 1 respectively; one end of the mounting plate 41 of the first short-side connecting member 4 protrudes outside the short side of the first panel 1, and the protruding end of the mounting plate 41 of the first short-side connecting member 4 is inserted into the insertion gap 42 above the second panel 1 when the short sides of the two panels 1 are in mutual contact. The top end of the mounting plate 41 of the first short-side connecting member 4 abuts against the abutting portion 43 of the second short-side connecting member 4, and the bottom end abuts against the top end of the second panel 1.

[0033] Specifically, the two short - side connectors 4 are respectively fixedly connected to the tops of the two panels 1, so that insertion gaps 42 are respectively formed between the bottoms of the two abutting portions 43 and the tops of the two panels 1, thereby fixedly connecting the two short - side connectors 4 and the two panels 1 respectively. One end of the mounting plate 41 of the first short - side connector 4 protrudes outside the short side of the first panel 1. Push the two panels 1 so that the short sides arranged opposite to each other on the two panels 1 move closer. When the short sides of the two panels 1 abut against each other, the end of the mounting plate 41 of the first short - side connector 4 that protrudes from the first panel 1 is inserted into the insertion gap 42 above the second panel 1. The top of the mounting plate 41 of the first short - side connector 4 abuts against the abutting portion 43, and the bottom abuts against the top of the second panel 1, so that the first short - side connector 4 and the second short - side connector 4 are stably connected, and further the short sides of the two panels 1 are stably connected. The installation is convenient, solving the connection problem of the short sides of the two panels 1. At the same time, there is no gap left at the joint of the short sides of the two panels 1, and the aesthetic degree of the space is also improved. The short - side connectors 4 arranged at the butt joints of the short sides of the adjacent two panels 1 are inserted and matched to achieve the splicing of the short sides of the adjacent two panels 1.

[0034] Specifically, the mounting plate 41 can be fitted and installed on the top of the panel 1, that is, fitted and installed on the back of the panel 1, and the installation is convenient. The mounting plate 41 can be bonded to the panel 1. The mounting plate 41 can be provided with a first fixing hole penetrating through it, and the panel 1 is provided with a second fixing hole. The short - side connector 4 further includes a second fastening portion 44 with one end passing through the first fixing hole and fixedly connected to the second fixing hole and the other end abutting against the top of the mounting plate 41. The second fastening portion 44 can be a screw. The two short - side connectors 4 are respectively fixed to the tops of the corresponding panels 1, that is, fixed to the back of the panel 1. At least the second fixing hole in the first fixing hole and the second fixing hole is a threaded hole that can be screwed to the screw.

[0035] The hanging member 2 can include a hanging portion 21 and a keel 22. The keel 22 includes a fixing portion. The hanging portion 21 includes a receiving cavity 211 formed with a hollow interior for the keel 22 to be inserted, an opening 212 provided at the top for the keel 22 to be snapped into the receiving cavity 211, two hanging plates 214 for respectively lapping on the top of the keel 22, and a guiding plate 213 for matching with the fixing portion to limit the horizontal movement of the hanging member. The two hanging plates 214 are respectively located on both sides of the opening 212.

[0036] Specifically, the inside of the hanging part 21 is hollow, so that a receiving cavity 211 is formed inside the keel 22. The opening 212 is communicated with the receiving cavity 211. The axis of the opening 212 can coincide with the axis of the receiving cavity 211. The opening 212 is located above the receiving cavity 211. Apply a force to the hanging part 21 to expand the opening 212, so that the keel 22 can pass through the opening 212 and be snapped into the receiving cavity 211. After the keel 22 is inserted into the receiving cavity 211, remove the force applied to the hanging part 21, and the opening 212 can return to its initial size. At this time, the hanging plate 214 can be lapped on the top of the keel 22. When the keel 22 is lifted, the hanging part 21 can be lifted. At the same time, the guiding plate 213 can match with the fixing part to limit the movement of the hanging part 21 in the horizontal direction, improving the connection stability between the hanging part 21 and the keel 22.

[0037] Specifically, the two hanging plates 214 can be symmetrically arranged, and the two hanging plates 214 are horizontally arranged.

[0038] The guiding plates 213 can be two respectively connected to one ends of the two hanging plates 214 close to the opening 212. The keel 22 includes two supporting plates 222 for respectively supporting the two hanging plates 214. The fixing part includes two first limiting plates 223 with one ends respectively connected to the two supporting plates 222, a first fixing plate 224 with both ends respectively connected to the other ends of the two first limiting plates 223, and a groove 221 formed by the first fixing plate 224 and the two first limiting plates 223 and recessed towards the inner side of the keel 22. The two guiding plates 213 respectively extend into the groove 221 and respectively abut against the two first limiting plates 223. The hanging member 2 further includes a first fastening part 23 with one end passing through the first fixing plate 224 and fixedly connected to the top of the wall.

[0039] Specifically, a concave groove 221 is formed at the middle position of the top of the keel 22. The groove 221 can be an isosceles trapezoid. The guiding plate 213 abuts and cooperates with the first limiting plate 223 to realize the horizontal limit of the hanging part 21. And the first fixing plate 224 can be used to install screws to be fixedly connected with the wall. The groove 221 is recessed towards the inner side of the keel 22, that is, the first fixing plate 224 is lower than the supporting plate 222, which can increase the vertical distance between the installation surface of the screw and the wall surface, making the connection between the keel 22 and the wall more firm after the screw is installed. The first fastening part 23 can be an expansion bolt.

[0040] Specifically, the two guiding plates 213 can be symmetrically arranged, and the two first limiting plates 223 are symmetrically arranged.

[0041] Specifically, the groove 221 can be an isosceles trapezoidal groove with the length of the top end greater than that of the bottom end, and the two guiding plates 213 are inclined towards each other. The inclined guiding plates 213 facilitate the insertion of the keel 22 into the hanging part 21, and at the same time can cooperate with the keel 22 for limiting to prevent the horizontal displacement of the hanging part 21.

[0042] The hanging part 21 may further include two first connecting plates 215 with the top ends respectively connected to the ends of the two hanging plates 214 far away from the opening 212, and a bottom plate 216 with the two ends respectively connected to the bottom ends of the two first connecting plates 215. A second insertion groove 217 is provided on one of the first connecting plates 215, and a first insertion through hole 218 communicating with the second insertion groove 217 is provided on the side surface of the bottom plate 216 connected to the first connecting plate 215. The long side connecting piece 3 includes a first insertion plate 32, a second insertion plate 33, and a first substrate 31. The first insertion plate 32 is inserted into the second insertion groove 217, the two ends of the second insertion plate 33 are respectively inserted into the first insertion grooves 11 on two adjacent panels 1, and the top end of the first substrate 31 passes through the first insertion through hole 218 and is connected to the middle of the first insertion plate 32, and the other end is connected to the middle of the second insertion plate 33.

[0043] Specifically, the second insertion plate 33 can be parallel to the first insertion plate 32, and the first substrate 31 can be perpendicular to the first insertion plate 32, that is, the long side connecting piece 3 can be an I-shaped piece, and the length of the first insertion plate 32 can be greater than the length of the second insertion plate 33.

[0044] Specifically, a first rounded corner can be provided at the connection between the guiding plate 213 and the hanging plate 214, and a second rounded corner is provided at the connection between the first limiting plate 223 and the supporting plate 222. Third rounded corners are provided at the connections between the first connecting plate 215 and the hanging plate 214, and between the first connecting plate 215 and the bottom plate 216. The outer shape of the hanging part 21 is an isosceles trapezoid, and the length of the bottom plate 216 is less than the distance between the ends of the two hanging plates 214 far away from the opening 212, that is, the hanging part 21 is an inverted isosceles trapezoid with the length of the upper base greater than that of the lower base.

[0045] There can be an installation gap between the bottom end of the keel 22 and the bottom end of the accommodation cavity 211 when the top end of the keel 22 abuts against the hanging plate 214.

[0046] Specifically, after the keel 22 is integrally inserted into the hanging part 21, there is a certain gap between its bottom end and the bottom end of the accommodation cavity 211, so that when the keel 22 is taken out, it can first move downward by a certain distance to disengage the guiding plate 213 from the keel 22, and then the opening 212 is enlarged to facilitate the smooth removal of the keel 22. At the same time, the gap provided between the bottom end of the keel 22 and the bottom end of the accommodation cavity 211 can ensure that the keel 22 can be smoothly inserted into the accommodation cavity 211.

[0047] The keel 22 may further include two second connecting plates 225 whose tops are respectively connected to the ends of the two support plates 222 away from the first limiting plate 223, and arc-shaped shock-absorbing plates 226 respectively connected to the bottoms of the two second connecting plates 225 for shock absorption when abutting against the bottom end of the accommodating cavity 211.

[0048] Specifically, when the keel 22 is taken out, it can first move downward by a certain distance to disengage the guiding plate 213 from abutting against the keel 221. At this time, the arc-shaped shock-absorbing plate 226 first abuts against the bottom plate 216, and the arc-shaped shock-absorbing plate 226 can protect the bottom plate 216 from shock.

[0049] Specifically, the first connecting plate 215 can be an elastic connecting plate and / or the hanging plate 214 can be an elastic hanging plate. Then, the two first connecting plates 215 can be respectively pulled in a direction away from each other or the two hanging plates 214 can be respectively pulled in a direction away from each other, so that when the opening 212 is pulled by an external force, the size of the opening 212 can be expanded to a preset size, and when the pulling force is withdrawn, the opening 212 can return to its initial size.

[0050] The short-side connector 4 may further include a second limiting plate 47 connected to the other end of the mounting plate 41, and a third connecting plate 48 with two ends respectively connected to the abutting portion 43 and the second limiting plate 47. The second limiting plate 47, the third connecting plate 48, the panel 1, and the abutting portion 43 enclose a limiting cavity 46. The second limiting plate 47 of the second short-side connector 4 is used to limit the mounting plate 41 of the first short-side connector 4 when the mounting plate 41 of the first short-side connector 4 is inserted into the insertion gap 42 and moves into the limiting cavity 46.

[0051] Specifically, the mounting plate 41, the second limiting plate 47, and the third connecting plate 48 can be integrally formed. The second limiting plate 47 is disposed above the mounting plate 41, and an abutting portion 43 is formed at the free end of the third connecting plate 48. The mounting plate 41 is parallel to the panel 11. The second limiting plate 47 can be perpendicular to the mounting plate 41, the third connecting plate 48 can be perpendicular to the second limiting plate 47, the third connecting plate 48 can also be inclined upward, and the third connecting plate 48 can also be inclined downward, so that a plugging gap 42 is formed between the bottom end of the abutting portion 43 and the top end of the panel 1. Push the first panel 1 in the direction of the second panel 1, so that the mounting plate 41 of the first short-side connecting member 4 moves toward the plugging gap 42. After the mounting plate 41 of the first short-side connecting member 4 is plugged into the plugging gap 42, continue to push the first panel 1. At this time, one end of the mounting plate 41 of the first short-side connecting member 4 is inserted into the limiting cavity 46. Continue to push the first panel 1, then at this time, the mounting plate 41 of the first short-side connecting member 4 continues to move in the limiting cavity 46, and the mounting plate 41 of the first short-side connecting member 4 moves toward the second limiting plate 47 of the second short-side connecting member 4. Then the second limiting plate 47 can limit the mounting plate 41 of the first short-side connecting member 4, and can prevent the mounting plate 41 of the first short-side connecting member 4 from hitting the mounting plate 41 of the second short-side connecting member 4.

[0052] The short-side connecting member 4 may further include a stop block 45 disposed near one end of the mounting plate 41. The height of the top end of the stop block 45 is higher than the height of the top end of the mounting plate 41. The stop block 45 of the first short-side connecting member 4 is disposed in the limiting cavity 46 when the end of the mounting plate 41 of the first short-side connecting member 4 protruding from the first panel 1 is plugged into the plugging gap 42, and is used to limit the mounting plate 41 of the first short-side connecting member 4 when the mounting plate 41 of the first short-side connecting member 4 moves in the direction away from the limiting cavity 46.

[0053] Specifically, the second panel 1 and the first panel 1 are arranged left and right. When the mounting plate 41 of the first short-side connecting member 4 is plugged into the plugging gap 42 above the second panel 1, the stop block 45 of the first short-side connecting member 4 is disposed in the limiting cavity 46. The two side ends of the stop block 45 of the first short-side connecting member 4 can respectively abut against the second limiting plate 47 and the abutting portion 43. When the two panels 1 move away from each other, the first panel 1 drives the mounting plate 41 of the first short-side connecting member 4 to move to the right, and the second panel 1 drives the abutting portion 43 of the second short-side connecting member 4 to move to the left. At this time, the stop block 45 of the first short-side connecting member 4 will be driven by the first panel 1 to move to the right, and then the stop block 45 will abut against the abutting portion 43. Thus, the stop block 45 limits the mounting plate 41 of the first short-side connecting member 4 to prevent the two panels 1 from loosening and improve the connection stability of the two panels 1.

[0054] Specifically, the bottom end of the stopper 45 can be flush with the bottom end of the mounting plate 41, and one side surface of the stopper 45 is fixedly connected to one side surface of the mounting plate 41. The stopper 45 can apply a certain pressure to the top end of the panel 1, further improving the stability of the connection between the two panels 1.

[0055] Specifically, the stopper 45 is detachably connected to the mounting plate 41. After inserting the mounting plate 41 of the first short-side connector 4 into the insertion gap 42 on the second panel 1, the stopper 45 can be connected to the mounting plate 41. When it is necessary to disassemble the two panels 1, first remove the stopper 45 from the mounting plate 41, and then separate the mounting plate 41 of the first short-side connector 4 from the insertion gap 42 on the second panel 1.

[0056] Specifically, the short-side connector 4 can also include a first connecting portion with two ends respectively connected to the second limiting plate 47 and the third connector, and a second connecting portion with two ends respectively connected to the third connecting plate 48 and the abutting portion 43. The first connecting portion and / or the second connecting portion is an elastic connecting portion; when the first connecting portion is an elastic connecting portion, the third connecting portion can move away from the panel 1 when pulled by an external force to increase the size of the insertion gap 42, and can move towards the panel 1 when the external force is removed to make the insertion gap 42 return to the initial size; when the second connecting portion is an elastic connecting portion, the abutting portion 43 can move away from the panel 1 when pulled by an external force to increase the size of the insertion gap 42, and can move towards the panel 1 when the external force is removed to make the insertion gap 42 return to the initial size. The first connecting portion and / or the second connecting portion being an elastic connecting portion facilitates pushing the stopper 45 of the first short-side connector 4 into the limiting cavity 46.

[0057] Specifically, the abutting portion 43 can be an arc abutting portion 43. The free end of the arc abutting portion 43 extends into the limiting cavity 46, and the arc side surface abuts against the mounting plate 41. The radian of the arc abutting portion 43 can be greater than 90 degrees and less than 360 degrees. The stopper 45 includes two inclined surfaces symmetrically arranged about the axis of the stopper 45 and matching the arc side surface of the arc abutting portion 43. The cross-section of the stopper 45 can be an isosceles triangle, and the angle between the inclined surface and the bottom surface of the stopper 45 can be 45 degrees. The matching of the inclined surface and the arc side surface of the arc abutting portion 43 facilitates pushing the stopper 45 into the limiting cavity 46.

[0058] Specifically, the interior of the hanging part 21 is hollow to form a receiving cavity 211. The outer shape of the hanging part 21 is an isosceles trapezoid. An opening 212 for the keel 22 to be inserted is formed at the middle position of the top of the hanging part 21. Horizontal extension hanging plates 214 are formed on both sides of the opening 212. An inclined guide plate 213 is formed at the inner end of the support plate 222 so that the keel 22 can be inserted into the interior of the hanging part 21 and can cooperate with the keel 22 for limiting to prevent the hanging part 21 from shifting horizontally. The two opposite side edges of the hanging part 21 can be deformed outward to make the opening 212 larger, facilitating the overall insertion of the keel 22. After the keel 22 is integrally inserted, the deformation of the two side edges is restored. After the keel 22 is integrally inserted into the hanging part 21, there is a certain gap between its bottom and the bottom wall of the hanging part 21, so that when the keel 22 is taken out, it can first move downward a certain distance to disengage the guide plate 213 from the keel 22, facilitating the smooth removal and insertion of the keel 22. A concave groove 221 is formed at the middle position of the top of the keel 22. The groove 221 is an isosceles trapezoid. The guide plate 213 abuts and cooperates with the side wall of the groove 221 to achieve the horizontal limit of the hanging part 21. And the bottom end of the groove 221 is used for installing screws to be fixedly connected to the wall, which can increase the vertical distance between the installation surface of the screws and the wall surface, making the connection between the keel 22 and the wall more firm after the screws are installed. The hanging part 21 in this application is convenient for installation and disassembly and can form a stable connection structure with the keel 22, making the panel 1 more stable when hung on the hanging part 21, and the installation accuracy of the panel 1 is easier to ensure.

[0059] Specifically, the spliced ceiling of this application is spliced in two directions of the long side and the short side. Among them, at the long side, the keel 22 is fixed to the wall through expansion bolts. A plurality of hanging parts 21 are clamped along the length direction of the keel 22. Each hanging part 21 is located at the splicing position of two adjacent panels 1. The hanging part 21 and the panel 1 are connected together through a long side connecting piece 3. Among them, the keel 22 and the hanging part 21 can form a stable hanging piece 2, improving the structural stability of the long side splicing of the panel 1 and effectively preventing the hanging part 21 from shifting, so as to ensure the installation accuracy of the panel 1. At the short side, two short side connecting pieces 4 are respectively fixed to the back of the corresponding panel 1 through screws. The splicing of the short side of the panel 1 is realized through the insertion and cooperation between the two short side connecting pieces 4. And a stop block 45 is arranged in the short side connecting piece 4, which can effectively prevent the short side connecting piece 4 from loosening, thereby improving the structural stability of the short side splicing of the panel 1. At the same time, seamless splicing of the short side of the panel 1 can be realized, and the installation accuracy of the panel 1 is easier to ensure, effectively improving the overall structural stability of the ceiling and ensuring the installation accuracy of the ceiling.

[0060] The installation method of the installation structure of the assembled spliced ceiling includes the following steps:

[0061] S1: Insert the two side ends at the bottom of a long-side connector 3 into the first insertion slots 11 of two adjacent panels 1 respectively.

[0062] S2: Connect one end of a short-side connector 4 to a panel 1, and connect the other ends of two short-side connectors 4 to each other when the short sides of two adjacent panels 1 corresponding to them are in mutual contact.

[0063] S3: Connect the bottom end of a hanging member 2 to the top of the long-side connector 3 and connect the top end to the wall top.

[0064] Specifically, conduct wire laying and positioning, drive expansion bolts, install the keel 22 basic structure, and adjust the expansion bolts for leveling; directly fix the keel 22 to the wall with expansion bolts; the hanging part 21 in the long side direction of the panel 1 matches the keel 22 and is fixed in a snap-fastening form; the hanging part 21 passes through the long-side connector 3 below, and the long-side connector 3 is snapped into the first insertion slot 11 of the panel 1; two short-side connectors 4 in the short side direction of the panel 1 are fixed to the back of the panel 1 with screws and are in insertion fit; when it is necessary to repair or replace the decorative panel 1, the decorative panel 1 can be disassembled conveniently and quickly; the disassembled decorative panel 1 can also be reused.

[0065] Specifically, at the long side of the panel 1, the keel 22 is connected to the hanging part 21 in a snap-fastening manner; the keel 22 is of full length, and multiple hanging parts 21 are distributed in a dot pattern on the keel 22 to jointly bear the panel 1; at the short side of the panel 1, the short-side connector 4 is connected in an insertion and buckling manner and fixed by nailing. Through the update of the connection method of the entire base layer and surface layer, the installation speed is made more convenient and fast while reducing nailing fixation, meeting the requirements of prefabrication.
