Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0032] Please see Figures 1 to 9 An embodiment of the present invention provides a prefabricated ceiling edge trimming and flat-joint installation device, comprising a flat-joint component 4, a hanging component 5, two wall panels 1, two edge trimming components 2, and at least two ceiling panels 3; the two wall panels 1 are respectively disposed on the base layer of the walls on both sides; one end of the two edge trimming components 2 near the base layer of the walls is respectively connected to the two wall panels 1; multiple ceiling panels 3 are sequentially installed along the direction from one wall panel 1 to another wall panel 1, the end of the ceiling panel 3 located at the end near the base layer of the walls is connected to an edge trimming component 2, and the ends of two adjacent ceiling panels 3 that are close to each other are respectively connected to a flat-joint component 4; the bottom end of the hanging component 5 is connected to the top end of the flat-joint component 4.

[0033] Here, the wall base can be the original wall or a leveling structure fixed to the original wall. Two wall panels 1 can be fixedly connected to the two sides of the original wall, or they can be fixedly connected to two leveling structures fixed to the original wall. The two wall panels 1 are fixedly connected to the left and right sides of the original wall, respectively. Two edge trims 2 are connected to the two wall panels 1. Multiple ceiling panels 3 are installed sequentially from one wall panel 1 to another, i.e., from left to right. The end of the ceiling panel 3 located at the left end, near the left side of the original wall, is connected to the edge trim 2 located on the left. The end of the ceiling panel 3 located at the right end, near the right side of the original wall, is connected to the edge trim 2 located on the right. The ends of two adjacent ceiling panels 3 that are close to each other are each connected to a flat connector 4. The edge trims 2 can finish the edges of the ceiling panels 3 located at the ends, improving the stability and aesthetics of the ceiling system.

[0034] Specifically, the hanging brackets 5 can be configured in a one-to-one correspondence with the flat connectors 4, so that each hanging bracket 5 can lift each flat connector 4, thereby lifting two adjacent ceiling panels 3 respectively, improving the stability of the ceiling panel 3 installation. If there are two ceiling panels 3, one flat connector 4, and one hanging bracket 5. If there are N ceiling panels 3, where N is an integer greater than or equal to 3, then there are N-1 flat connectors 4 and N-1 hanging brackets 5.

[0035] The edge trim 2 may include a first overlapping plate 21, a first support plate 22, and a first limiting plate 23. The top end of the first limiting plate 23 is connected to the bottom end of the first overlapping plate 21, and the bottom end is connected to the first support plate 22. The first overlapping plate 21 overlaps the top end of the wall panel 1, and the end of the ceiling panel 3 located at the end, close to the wall base, overlaps the first support plate 22.

[0036] Specifically, the first overlapping plate 21 overlaps the top of the wall panel 1, so that the wall panel 1 supports the first overlapping plate 21. The ceiling panel 3 overlaps the first support plate 22, so the first support plate 22 supports the ceiling panel 3. When the ceiling panel 3 overlaps the first support plate 22, the first limiting plate 23 can limit the end of the ceiling panel 3 that is close to the wall base. The end of the ceiling panel 3 that is close to the wall base abuts against the first limiting plate 23.

[0037] The edge trimming component 2 may also include an edge trimming fixing plate 24 connected to the top of the first overlapping plate 21, and a first fastening part 25 for fixing the edge trimming fixing plate 24 to the wall base.

[0038] Specifically, one end of the first fastening part 25 passes through the edge fixing plate 24 and is fixedly connected to the wall base, thereby fixing the edge fixing plate 24 to the wall base. The first overlapping plate 21 is perpendicular to the top of the wall panel 1, the first limiting plate 23 is perpendicularly connected to the bottom of the first overlapping plate 21, the first support plate 22 is perpendicularly connected to the bottom of the side of the first limiting plate 23 away from the wall base, and the edge fixing plate 24 is perpendicularly connected to the top of the first overlapping plate 21. The length of the first overlapping plate 21 is greater than the thickness of the wall panel 1, thus creating an installation gap between the first limiting plate 23 and the wall panel 1, preventing the first limiting plate 23 from squeezing the wall panel 1. The first fastening part 25 can be a screw, bolt, or bolt. The edge trimming part 2 can be a one-piece molded component.

[0039] The flat connector 4 may include a first snap-fit ​​structure 41, a second snap-fit ​​structure 42, and a first lifting structure 43 whose bottom ends are respectively connected to the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42. The first snap-fit ​​structure 41 and the second snap-fit ​​structure 42 are respectively connected to the close ends of two adjacent ceiling panels 3, and the bottom end of the hanging component 5 is connected to the top end of the first lifting structure 43.

[0040] The first snap-fit ​​structure 41 may include a first ceiling connection part, a first hanging plate 411, and a first insertion groove 412 disposed on the first hanging plate 411; the second snap-fit ​​structure 42 includes a second ceiling connection part, a second hanging plate 421, and a second insertion groove 422 disposed on the second hanging plate 421; the first ceiling connection part and the second ceiling connection part are respectively connected to the close ends of two adjacent ceiling panels 3; a first insertion through hole 45 is provided between the first hanging plate 411 and the second hanging plate 421; the first lifting structure 43 includes a first lifting plate 431, a first insertion plate 432 and a second insertion plate 433 respectively connected to the two sides of the first lifting plate 431, the top end of the first lifting plate 431 is connected to the hanging member 5, the bottom end is inserted into the first insertion through hole 45, the first insertion plate 432 is inserted into the first insertion groove 412, and the second insertion plate 433 is inserted into the second insertion groove 422.

[0041] Specifically, the first insertion plate 432 is inserted into the first insertion slot 412, and the second insertion plate 433 is inserted into the second slot, so the first lifting structure 43 can lift the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42 respectively. The bottom end of the first lifting plate 431 is inserted into the first insertion through hole 45, which facilitates the insertion of the first insertion plate 432 into the first insertion slot 412 and the insertion of the second insertion plate 433 into the second insertion slot 422. When the first insertion slot 412 and the second insertion slot 422 are both horizontally set, the first insertion plate 432 and the second insertion plate 433 are also horizontally set. At this time, the bottom end of the first hanging plate 411 can be connected to the first lifting connection part, and the bottom end of the second hanging plate 421 can be connected to the second ceiling connection part. The hanging component 5 may include a hanging rod, the top of which is connected to the top of the wall. The top of the first lifting plate 431 passes through the first insertion hole 45 and protrudes above the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42. The bottom of the hanging rod is fixedly connected to the first lifting plate 431.

[0042] Specifically, the first mounting plate 411 is horizontally arranged, the first insertion slot 412 may include multiple first base slots, which are respectively inclined and have different inclinations. The multiple first base slots are connected, and the first insertion plate 432 may include multiple first insertion substrates, which are interconnected. The multiple first insertion substrates are respectively inclined and have different inclinations. At the node connection between the first lifting structure 43 and the first snap-fit ​​structure 41, different first insertion substrates are matched with different first base slots. Multiple inclinations can help the first insertion plate 432 and the first mounting plate 411 fit more tightly and have better fixation. There can be two first base slots and two first insertion substrates, so the first insertion plate 432 has two types of first insertion substrates with different inclinations. The second mounting plate 421 is horizontally arranged, and the second insertion slot 422 may include multiple second base slots. The multiple second base slots are respectively inclined and have different inclinations. The multiple second base slots are connected. The second insertion plate 433 may include multiple second insertion substrates. The multiple second insertion substrates are interconnected and are respectively inclined and have different inclinations. At the node connection between the first lifting structure 43 and the first snap-fit ​​structure 41, different second insertion substrates are matched with different second base slots. Multiple inclinations can help the second insertion plate 433 and the second mounting plate 421 fit more tightly and have better fixation. There can be two second base slots and two second insertion substrates. Then the second insertion plate 433 has two types of second insertion substrates with different inclinations.

[0043] Specifically, the first mounting plate 411 and the second mounting plate 421 can be symmetrically arranged, the first insertion slot 412 and the second insertion slot 422 can be symmetrically arranged, and the first insertion plate 432 and the second insertion plate 433 can be symmetrically arranged. The first insertion plate 432 and the second insertion plate 433 are both horizontally arranged, and the first lifting plate 431 is vertically arranged. The first insertion plate 432 and the second insertion plate 433 form a hook-like structure with the first lifting plate 431.

[0044] At least one end of the ceiling panel 3 may be provided with a third insertion slot 31. The first ceiling connection part includes a third insertion plate 413 and a second limiting plate 414 connected to the top of the third insertion plate 413. The second ceiling connection part includes a fourth insertion plate 423 and a third limiting plate 424 connected to the top of the fourth insertion plate 423. The third insertion plate 413 and the fourth insertion plate 423 are respectively inserted into two third insertion slots 31 that are close to each other on two adjacent ceiling panels 3. The second limiting plate 414 and the third limiting plate 424 respectively abut against one end of the two adjacent ceiling panels 3 that are close to each other.

[0045] Specifically, when there are two ceiling panels 3, only the two adjacent ends of the two ceiling panels 3 need to be provided with third insertion slots 31, and then the first ceiling connection part and the second ceiling connection part of a flat connector 4 are respectively connected to the two third insertion slots 31 on the two ceiling panels 3. When there are more than two ceiling panels 3, a third insertion slot 31 is provided at one end of the ceiling panel 3 located at the end, and two third insertion slots 31 are provided at both ends of the ceiling panel 3 located in the middle. The first ceiling connection part of a flat connector 4 located at one end is connected to the third insertion slot 31 of the ceiling panel 3 located at one end, and the second ceiling connection part is connected to the third insertion slot 31 of the ceiling panel 3 located in the middle. The first ceiling connection part of a flat connector 4 located in the middle is connected to the third insertion slot 31 of the ceiling panel 3 located in the middle, and the second ceiling connection part is connected to the third insertion slot 31 of the other ceiling panel 3 located in the middle.

[0046] Specifically, the third insertion plate 413 and the fourth insertion plate 423 are respectively inserted into two adjacent third insertion slots 31 on two adjacent ceiling panels 3, so that the first snap-fit ​​structure 41 is connected to one ceiling panel 3 and the second snap-fit ​​structure 42 is connected to the other ceiling panel 3. The second limiting plate 414 and the third limiting plate 424 abut against one end of the two adjacent ceiling panels 3, so that the second limiting plate 414 can limit the third insertion plate 413 when it is inserted into the third insertion slot 31, and the third limiting plate 424 can limit the fourth insertion plate 423 when it is inserted into the fourth insertion slot. The third limiting plate 424 and the fourth limiting plate can abut against each other to limit the joint between two adjacent ceiling panels 3. The second limiting plate 414 and the third plug-in plate 413 are integrally formed, and the third limiting plate 424 and the fourth plug-in plate 423 are integrally formed, thus realizing the overall installation of the flat joint 4 and the two ceiling panels 3, and no longer separating them into caulking strips and ceiling base.

[0047] The first ceiling connection part may also include a first fixing plate 415 connected to the top of the second limiting plate 414, and the second ceiling connection part may also include a second fixing plate 425 connected to the top of the third limiting plate 424. The flat connector 4 may also include a second fastening part 44, which is used to fix at least one of the first fixing plate 415 and the second fixing plate 425 to its corresponding ceiling plate 3.

[0048] Specifically, the second fastening part 44 can fix the first fixing plate 415 and its corresponding ceiling plate 3. The first fixing plate 415 abuts against the top of the ceiling plate 3 located on the left side, and the second fixing plate 425 abuts against the top of the ceiling plate 3 located on the right side. The flat connector 4 can control the height difference between the two ceiling plates 3 and reduce errors. The second fastening part 44 can be a screw, bolt, or bolt. The length of the first fixing plate 415 is greater than the length of the second fixing plate 425. The ceiling plate 3 is horizontally set, the third insertion slot 31 is horizontally set, the third insertion plate 413 and the fourth insertion plate 423 are both horizontally set, the second limiting plate 414 is perpendicular to the third insertion plate 413, and the third limiting plate 424 is perpendicular to the fourth insertion plate 423.

[0049] The first snap-fit ​​structure 41 may further include a first connecting plate 416 connected to the first hanging plate 411 and the first ceiling connection portion respectively, and a first receiving groove 418 formed by the first hanging plate 411, the first connecting plate 416, and the first ceiling connection portion. The second snap-fit ​​structure 42 further includes a second connecting plate 426 connected to the second hanging plate 421 and the second ceiling connection portion respectively, and a second receiving groove 428 formed by the second hanging plate 421, the second connecting plate 426, and the second ceiling connection portion. The first lifting structure 43 also includes a second support plate 434 connected to the bottom end of the first lifting plate 431, and a first damping plate 435 and a second damping plate 436 respectively connected to the two sides of the second support plate 434. The first damping plate 435 is inserted into the first receiving groove 418 and abuts against the first connecting plate 416 to dampen the first connecting plate 416. The second damping plate 436 is inserted into the second receiving groove 428 and abuts against the second connecting plate 426 to dampen the second connecting plate 426.

[0050] Specifically, when horizontal vibration occurs when the first lifting plate 431 and the hanging component 5 are connected, the first damping plate 435 and the second damping plate 436 can help reduce horizontal vibration. The first damping plate 435 and the first connecting plate 416 are not completely fitted together, and the second damping plate 436 and the second connecting plate 426 are not completely fitted together, which can help resist the effects of horizontal deformation. Both the first damping plate 435 and the second damping plate 436 are arc-shaped plates; the arc design helps to reduce horizontal vibration. The first plug-in plate 432 is positioned above the first damping plate 435, and the second plug-in plate 433 is positioned above the second damping plate 436. When the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42 are connected to the first lifting structure 43, the upper half is the vertically fixed module, and the lower half is the horizontally curved damping module. The first damping plate 435 and the second damping plate 436 are symmetrically arranged. The bottom end of the first connecting plate 416 can abut against the first fixed plate 415.

[0051] Specifically, the bottom end of the first connecting plate 416 can be connected to the top end of the first fixing plate 415, and the bottom end of the second connecting plate 426 can be connected to the bottom end of the second fixing plate 425. The first connecting plate 416 is perpendicular to the first hanging plate 411, and the second connecting plate 426 is perpendicular to the second hanging plate 421. The first insertion slot 412 can be set on the first hanging plate 411 at the position where it connects with the first connecting plate 416, and the second insertion slot 422 can be set on the second hanging plate 421 at the position where it connects with the second connecting plate 426.

[0052] The first snap-fit ​​structure 41 may further include a first mounting plate 417 connected to the first connecting plate 416 near the middle of one side of the first receiving groove 418, and a first limiting groove 419 formed by the first mounting plate 417 and the first connecting plate 416. The second snap-fit ​​structure 42 may further include a second mounting plate 427 connected to the second connecting plate 426 near the middle of one side of the second receiving groove 428, and a second limiting groove 429 formed by the second mounting plate 427 and the second connecting plate 426. A second insertion through hole 46 is provided between the first mounting plate 417 and the second mounting plate 427. The second support plate 434 is inserted into the second insertion through hole 46. One end of the first damping plate 435 away from the second support plate 434 is inserted into the first limiting groove 419. One end of the second damping plate 436 away from the second support plate 434 is inserted into the second limiting groove 429.

[0053] Specifically, the first limiting groove 419 can limit the first damping plate 435, improving the damping effect of the first damping plate 435 on the first connecting plate 416; the second limiting groove 429 can limit the second damping plate 436, improving the damping effect of the second damping plate 436 on the second connecting plate 426; the first damping plate 435 is inserted into the first limiting groove 419, and the second damping plate 436 is inserted into the second limiting groove 429, improving the stability of the connection between the first lifting structure 43 and the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42 respectively. The first mounting plate 417 and the second mounting plate are symmetrically arranged, as are the first limiting groove 419 and the second limiting groove 429.

[0054] Specifically, the width of the second insertion hole 46 is smaller than the width of the first insertion hole 45, and the width of the first lifting plate 431 is larger than the width of the second support plate 434, thereby improving the overall strength of the first lifting structure 43.

[0055] An installation method for a prefabricated ceiling edge trim joint installation device includes the following steps:

[0056] S1: Place the two wall panels 1 on the base layer of the walls on both sides respectively;

[0057] S2: Connect the ends of the two edge trims 2 that are closest to the wall base to the two wall panels 1 respectively;

[0058] S3: Install multiple ceiling panels 3 sequentially along the direction from one wall panel 1 to another wall panel 1, connect the end of the ceiling panel 3 located near the wall base to a finishing piece 2, and connect the ends of two adjacent ceiling panels 3 that are close to each other to a flat joint 4 respectively.

[0059] S4: Connect the bottom end of the hanging part 5 to the top end of the flat connector 4.

[0060] Specifically, from left to right, ① connect and fix the first lifting plate 431 to the hanging component 5;

[0061] ② Fix the edge trim 2 to the wall panel 1 using bolts;

[0062] ③ The first snap-fit ​​structure 41 and the left ceiling panel 3 are connected and fixed by the second fastening part 44. The first snap-fit ​​structure 41, the left ceiling panel 3, and the second fastening part 44 are assembled on the ground to form a whole.

[0063] ④ Install the whole formed by the first snap-fit ​​structure 41, the second fastening part 44, and the left ceiling panel 3. The left edge of the ceiling panel 3 is attached to the edge trim 2, and the first plug-in plate 432 and the first shock-absorbing plate 435 on the right side are respectively snap-fitted to the first lifting structure 43.

[0064] ⑤ Fix the second snap-fit ​​structure 42 to the first lifting structure 43. The connection between the second hanging plate 421 and the second plug-in plate 433, and the connection between the second mounting plate 427 and the second shock absorber plate 436 are in close contact. The test standard for tight installation is that the second limiting plate 414 and the third limiting plate 424 are flush on the left and right.

[0065] ⑥ Installation of ceiling panel 3 on the right side: Fix ceiling panel 3 to the second snap-fit ​​structure 42 on the left side of ceiling panel 3. The connection node is the fourth plug-in plate 423. Keep the connection tight. Repeat the above operation on the right side of ceiling panel 3 as described in ③-④.

[0066] ⑦ Repeat steps ①-⑥ above until all ceiling panels 3 are installed.

[0067] Specifically, this application addresses the limitations of existing ceiling installation methods by optimizing the wall-to-ceiling connection nodes and reinforcing the overall stability of the ceiling structure. The application designs a structure for the flat joint of the ceiling panel 3, integrating the caulking strip and the interlocking plate for installation, reducing installation difficulty and accelerating the installation process. The interlocking connection method of the rear-mounted base layer behind the ceiling panel 3 controls the caulking width of the panel. This enhances the stability of the ceiling panel 3 after fixing, and the multi-point fixing method improves the stability and firmness of the panel.

[0068] Specifically, ① at the connection points of the first lifting structure 43 with the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42, the upper half is the vertical direction of the fixed module, and the lower half is the horizontal direction of the arc-shaped shock-absorbing module; at the node connection points of the first plug-in plate 432 and the first hanging plate 411, and the second plug-in plate 433 and the second hanging plate 421, the two slopes can help the first plug-in plate 432 and the first hanging plate 411, and the second plug-in plate 433 and the second hanging plate 421 fit more tightly and have better fixation;

[0069] ② At the connection between the first mounting plate 417 and the first damping plate 435, and the second mounting plate 427 and the second damping plate 436, when the first ceiling plate 3 is connected to the hanger and generates horizontal vibration amplitude, the arc design of the first damping plate 435 and the second damping plate 436 can help reduce horizontal vibration; the first damping plate 435 and the first mounting plate 417, and the second damping plate 436 and the second mounting plate 427 are not completely fitted together to resist the effects of horizontal deformation;

[0070] ③ At the connection points of the first snap-fit ​​structure 41 and the second snap-fit ​​structure 42 with the two ceiling panels 3, the primary purpose is to install them as a whole, without separating them into caulking strips and ceiling base layers; in addition, it can control the height difference between the panels and reduce errors.
