Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated suspended ceilings, and particularly to a prefabricated suspended ceiling system and an installation method thereof. Background Art

[0002] As a technology that is widely applied in current prefabricated decoration, prefabricated suspended ceiling decoration has been accepted and chosen by more and more users, and prefabricated decoration has the advantages of fast installation, safety and environmental protection. However, in order to achieve the purpose of fast installation, the existing prefabricated suspended ceilings often neglect the stability of the suspended ceiling system, resulting in the deformation of the structure of the prefabricated suspended ceiling in a relatively short time and a short service life.

[0003] For example, in the utility model patent with the patent application number CN202123205485.2 and the name of a prefabricated suspended ceiling, the suspended ceiling connecting piece is hung on the wall top, and the suspended ceiling board is connected to the bottom of the suspended ceiling connecting piece in a clamping form. The suspended ceiling connecting piece not only bears the weight of the suspended ceiling board but also is used to connect two adjacent suspended ceiling boards. However, in order to ensure the aesthetics of the suspended ceiling in the existing suspended ceiling system, the gap between adjacent suspended ceiling boards is usually only about 5 millimeters, which correspondingly results in an extremely small thickness of a part of the body at the lower end of the suspended ceiling connecting piece, leading to a short service life of the suspended ceiling connecting piece and not meeting the expectations of consumers. Summary of the Invention

[0004] The present invention provides a prefabricated suspended ceiling system in which the load-bearing structure of the suspended ceiling board and the connection structure of the suspended ceiling board are separated, and the pre-installed suspended ceiling boards can also be quickly connected to solve the above problems.

[0005] The technical solution adopted by the present invention to solve the above problems is: to provide a prefabricated suspended ceiling system, including a plurality of hanging components, a plurality of connecting pieces, and a plurality of suspended ceiling boards. The plurality of hanging components are all fixedly installed on the wall top, and each hanging component hangs a suspended ceiling board. The connecting pieces are used to connect adjacent suspended ceiling boards. The hanging component includes a suspender, a suspended ceiling keel, and a hanging piece. The upper end of the suspender is anchored and fixed on the wall top, the suspended ceiling keel is fixed to the lower end of the suspender, the hanging piece is fixedly installed on the suspended ceiling board, and the suspended ceiling keel is adaptively hung with the hanging piece.

[0006] Further, a first accommodating groove and a second accommodating groove are formed on the connecting piece. Both the first accommodating groove and the second accommodating groove are used to accommodate the board end body or part of the board end body of the suspended ceiling board, and the notch directions of the first accommodating groove and the second accommodating groove are opposite.

[0007] Further, it further includes a first fixing plate connected to the connecting piece. The first fixing plate is fixedly nailed to the suspended ceiling board, and the first fixing plate is parallel to the extending direction of the first accommodating groove or the second accommodating groove.

[0008] Further, it further includes a second fixing plate connected to the connecting member. The second fixing plate is in plug-in connection with the ceiling board, and the second fixing plate is parallel to the extending direction of the first receiving groove or the second receiving groove.

[0009] Further, the lower end of the hanging rod is provided with an external thread, a through hole adapted to the hanging rod is formed on the ceiling keel, and a limit nut screwed on the hanging rod is further included; when the hanging rod is inserted into the through hole, the limit nut is screwed on the hanging rod and is located below the ceiling keel to limit the ceiling keel.

[0010] Further, the hanging member is a C-shaped plate. When the hanging member is fixedly installed on the ceiling board, the opening of the hanging member faces upward.

[0011] Further, a limit plate that can be inserted into the hanging member is correspondingly formed on the ceiling keel; when the ceiling board is hung on the ceiling keel through the connecting member, the limit plate of the ceiling keel is correspondingly located in the inner cavity of the limit plate and cooperates with the connecting member to limit and mount the ceiling board.

[0012] Further, it further includes a ceiling trimming member arranged between the ceiling board and the wall board close to the wall. The ceiling trimming member is fixedly arranged on the top of the wall board, and the ceiling trimming member has a trimming structural plate for receiving the ceiling board.

[0013] Further, the ceiling trimming member further has a backlight groove for accommodating a backlight lamp.

[0014] The present invention also provides an installation method for an assembled ceiling system for installing an assembled ceiling system according to any one of the above, which is characterized by including the following installation steps:

[0015] Step S1: Fix and install the hanging rods at the predetermined positions on the wall top according to the design plan and drawings;

[0016] Step S2: Fix and install the hanging members in the middle of each ceiling board;

[0017] Step S3: Install the first ceiling board; raise the ceiling board equipped with the hanging member and the connecting member to the lower end of the hanging rod, and in a side-sliding manner, make the limit plate of the ceiling keel enter the inside of the hanging member;

[0018] Step S4: Install the second ceiling board; install the connecting member at the connecting edge position between the second ceiling board and the first ceiling board, repeat Step S3 to hang the second ceiling board, and after hanging the second ceiling board, push the second ceiling board laterally to make the corresponding side of the first ceiling board correspondingly inserted into the corresponding connecting member;

[0019] Step S5: Repeat Step S4 to successively install all subsequent ceiling panels.

[0020] Advantages of the present invention:

[0021] 1. The weight of the ceiling panel is borne by the hanging assembly, and the ceiling panels are connected by connecting members, thus effectively avoiding the problem that the hanging structure has a weak load-bearing part due to the additional hanging structure at the connecting member, resulting in the deformation of the connecting member under load.

[0022] 2. The ceiling panel can be slidably hung on the lower end of the suspender, and adjacent ceiling panels only need to be pushed laterally to be inserted into the corresponding receiving grooves of the same connecting member to be connected to each other, making the installation of the ceiling panel relatively convenient.

[0023] 3. The ceiling panel is hung on the suspender in a side-sliding manner, and adjacent ceiling panels only need to be respectively inserted laterally into the first receiving groove and the second receiving groove of a connecting member to be connected to each other; in this way, even for the last ceiling panel, there is no need to worry about the problem that it is difficult to connect the ceiling panel to the suspender and to the adjacent ceiling panel due to the lack of operable space.

[0024] 4. Based on the installation method of the present invention, the installation of the ceiling panel is simple and convenient, which can effectively shorten the installation period of the ceiling system and ensure the installation quality of the ceiling system.

The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0038] First embodiment:

[0039] Please refer to Figures 1 to 8 , an assembled ceiling system in a specific embodiment of the present invention includes a plurality of suspension assemblies 1, a plurality of connecting pieces 2, and a plurality of ceiling panels 3. Each adjacent two ceiling panels 3 are connected to each other through the connecting piece 2, and each suspension assembly 1 is used to suspend a ceiling panel 3.

[0040] In this embodiment, each suspension assembly 1 includes a suspension rod 11, a ceiling keel 12, and a hanging piece 13. The suspension rod 11 is a straight rod. The upper end of the suspension rod 11 is fixed to the wall top, and the lower end is provided with an external thread. Moreover, a limit nut 14 is further provided at the lower end of the suspension rod 11. A through hole for the lower end of the suspension rod 11 to insert is formed on the ceiling keel 12, and the diameter of the limit nut 14 is larger than the diameter of the through hole. When the suspension rod 11 is inserted into the through hole on the ceiling keel 12, the limit nut 14 is correspondingly screwed on the inserted end of the suspension rod 11 to limit the ceiling keel 12, so that the ceiling keel 12 is limit - hung at the lower end of the suspension rod 11.

[0041] On both sides of the lower end of the ceiling keel 12, limiting plates 15 are integrally provided, and the hanging member 13 is a C-shaped plate; at the middle position of each ceiling board 3, a hanging member 13 is fixedly arranged by screws. When the hanging member 13 is fixed on the ceiling board 3, the opening of the hanging member 13 faces upward; when hanging the ceiling board 3 on the lower end of the suspender 11, push the ceiling board 3 laterally, so that the two limiting plates 15 at the lower end of the ceiling keel 12 simultaneously slide laterally into the inner cavity of the hanging member 13, and the ceiling keel 12 is correspondingly located at the opening position of the hanging member 13. At this time, the two limiting plates 15 and the hanging member 13 cooperate to form a limiting structure to mount the ceiling board 3 fixed with the hanging member 13 on the lower end of the suspender 11, realizing the mounting of a single ceiling board 3.

[0042] In this embodiment, the number of suspenders 11 for hanging a ceiling keel 12 is not limited to one.

[0043] In this embodiment, the sum of the widths of the two limiting plates 15 and the ceiling keel 12 is still smaller than the width of the hanging member 13. For this reason, when the ceiling board 3 is mounted on the lower end of the hanging assembly 1, each ceiling board 3 can move laterally within a small range.

[0044] In this embodiment, the connecting member 2 is used to connect two adjacent ceiling boards 3. For the ceiling system, multiple ceiling boards 3 are correspondingly connected to each other through multiple connecting members 2 to form a whole, thus becoming a ceiling ceiling.

[0045] In this embodiment, the connecting member 2 is a multi-segment bent plate, and when the multi-segment bent plate is bent, a first receiving groove 21 and a second receiving groove 22 facing away from each other are formed. Both the first receiving groove 21 and the second receiving groove 22 are used to receive the flange bodies provided at the plate end body of the ceiling board 3; when the first receiving groove 21 and the second receiving groove 22 receive the flange bodies provided at the plate end body of the ceiling board 3, the flange bodies provided at the plate end body of the ceiling board 3 are in a tensioned state in the corresponding first receiving groove 21 or second receiving groove 22 to further prevent the ceiling board 3 from separating from the connecting member 2. And when the first receiving groove 21 and the second receiving groove 22 of a connecting member 2 both receive the ceiling board 3, it can be understood that two adjacent ceiling boards 3 are connected to each other through a connecting member 2.

[0046] Furthermore, since the thickness of the flange body extending from the end plate body is relatively thin, to prevent the connecting member 2 from being unable to stably connect two adjacent ceiling panels 3 due to the fracture of the flange body. In this embodiment, a first fixing plate 23 is further extended and provided at the upper end of the connecting member 2. The first fixing plate 23 is a plate body that horizontally extends from the upper end of the multi-segment bent plate. When the connecting member 2 connects two adjacent ceiling panels 3, nails can also be driven at the first fixing plate 23 to further fix the connecting member 2 and one of the ceiling panels 3. In addition, a second fixing plate 24 is further extended and provided at the lower end of the connecting member 2. The second fixing plate 24 is a plate body that horizontally extends from the lower end of the multi-segment bent plate. When the connecting member 2 connects two adjacent ceiling panels 3, the second fixing plate 24 can be correspondingly inserted into the slot on the side of the other ceiling panel 3 and tightly connected with the slot to further stabilize its connection relationship with the other ceiling panel 3.

[0047] It should be noted that, in this embodiment, when the second fixing plate 24 is provided at the lower end of the connecting member 2 and the second fixing plate 24 is inserted into the other ceiling panel 3 in a tightly plugged manner to stabilize the connection relationship between the connecting member 2 and the other ceiling panel 3, there will be no installation marks on the lower surface of the adjacent joint of the adjacent ceiling panels 3, which can improve the aesthetics of the assembled ceiling installation.

[0048] In fact, in this embodiment, the further fixed connection method between the first fixing plate 23 and the ceiling panel 3 can also be a tightly plugged connection method, and the further fixed connection method between the second fixing plate 24 and the ceiling panel 3 can also be a nailed connection. Moreover, after adding the first fixing plate 23 and the second fixing plate 24, the structure of the ceiling panel 3 itself will also correspondingly change, which will lead to an increase in the ceiling installation cost; in this regard, those skilled in the art can completely choose whether to additionally add the first fixing plate 23 and the second fixing plate 24 to the original connecting member 2 according to actual needs.

[0049] In this embodiment, all the ceiling panels 3 are hung below the wall top through the hanging components 1. And after the ceiling panels 3 are connected to each other as a whole through a plurality of connecting members 2, there is still a gap between the overall ceiling panels 3 formed and the wall. In this regard, a ceiling edge trim 4 is further provided between the ceiling panel 3 close to the wall and the wall panel provided on the wall. The ceiling edge trim 4 includes a fixing plate portion for inserting the upper end plate body of the wall panel to be fixed at the upper end of the wall panel and a trimming structural plate 41 extending from the fixing plate portion; when the ceiling edge trim 4 is fixed at the upper end of the wall panel, the trimming structural plate 41 is located below the corresponding ceiling panel 3 and contacts the corresponding ceiling panel 3 to achieve edge trimming.

[0050] In this embodiment, an installation method of an assembled ceiling system is used to install an assembled ceiling system described in any one of the above embodiments, including the following installation steps:

[0051] Step S1: According to the design scheme and drawings, fixedly install the suspender 11 at the predetermined position on the top of the wall.

[0052] Step S2: Fix and install the hanging member 13 in the middle of each ceiling board 3.

[0053] Step S3: Install the first ceiling board 3; raise the ceiling board 3 equipped with the hanging member 13 and the connecting member 2 to the lower end of the suspender 11, and in a side-sliding manner, make the limiting plate 15 of the ceiling keel 12 enter the inside of the hanging member 13.

[0054] Step S4: Install the second ceiling board 3; install the connecting member 2 at the connecting edge position between the second ceiling board 3 and the first ceiling board 3, repeat Step S3 to hang the second ceiling board 3, and after hanging the second ceiling board 3, push the second ceiling board 3 laterally so that the corresponding side edge of the first ceiling board 3 is correspondingly inserted into the corresponding connecting member 2.

[0055] Step S5: Repeat Step S4 to sequentially install all the subsequent ceiling boards 3.

[0056] Install the ceiling board 3 according to the above steps, which can realize the assembled installation of the ceiling system and will not encounter the problem of difficult installation of the last ceiling board 3.

[0057] Embodiment 2:

[0058] Different from Embodiment 1, the second receiving groove 22 is a receiving groove that can receive the plate end body of the ceiling board 3, and the upper end surfaces of the second receiving groove 22 and the first receiving groove 21 are flush, and moreover, the second fixing plate 24 also becomes a part of the groove structure of the second receiving groove 22.

[0059] In this embodiment, in order not to expose the connecting member 2 on the lower surface of the ceiling board 3, the second receiving groove 22 not only receives the flange body extending from the plate end body of the corresponding ceiling board 3, but also receives a part of the plate end body of the ceiling board 3.

[0060] Actually, since the thickness of the flange body extending from the plate end body is relatively thin, in order to prevent the connecting member 2 from being unable to stably connect two adjacent ceiling boards 3 due to the fracture of the flange body, when higher aesthetics are not considered, the second receiving groove 22 can directly receive a part of the plate end body of the corresponding ceiling board 3, so that the connection effect of the connecting member 2 when connecting adjacent ceiling boards 3 is more stable.

[0061] Based on this embodiment, when the thicknesses of two adjacent ceiling boards 3 are the same, when the second receiving groove 22 receives a part of the plate end body of the ceiling board 3, the first receiving groove 21 can still only receive the flange body at the plate end of another corresponding ceiling board 3. In this regard, the first fixing plate 23 can be used to further fixedly connect the connecting member 2 and another corresponding ceiling board 3.

[0062] Where not mentioned above, the prior art shall apply.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
