The ceiling includes a concave-shaped keel and a number of hanging parts that cooperate with the concave-shaped keel. An I-shaped part is fixedly connected below the hanging part, and a decorative panel is snap-connected between the bottoms of adjacent I-shaped parts.

Description

Technical Field

[0001] The present invention relates to the field of interior decoration, and particularly to a new type of hanging and assembled bathroom ceiling and its installation method. Background Art

[0002] The assembled decoration ceiling is a decoration method that produces material parts through factories and conducts on-site assembly and dry construction. Compared with the traditional woodworking ceiling decoration, the assembled integrated ceiling has various advantages such as easy installation and maintenance, not easily soiled, and diverse styles. In terms of materials, the materials of the assembled integrated ceiling mainly consist of light steel keels, suspenders, screws, gypsum boards, and joint fillers.

[0003] Currently, assembled bathroom ceilings usually have the following problems: There is no good solution for the edge treatment and the joint of two decorative panels in the assembled ceiling. It is time-consuming and laborious to install and splice the caulking strips on the site for the boards, and the gaps are uneven after installation, and it does not meet the fire prevention requirements, and it is easy to be misaligned during the splicing process. In addition, the edge trimming structure of the ceiling is usually installed by nailing, so the installation efficiency is relatively low, and it also increases the difficulty of subsequent disassembly. At the same time, nailing makes the boards prone to deformation problems, affecting the aesthetics and safety of the overall ceiling.

[0004] The prior art, such as a hook-type ceiling installation structure with the application number CN202010434202.2, includes a lead screw, a hanging member, a horizontal line, a vertical line, a trimming line, a ceiling board, and a filling board. Multiple horizontal lines and vertical lines are respectively installed below the wall top through multiple hanging members and lead screws. The horizontal lines are arranged at intervals in the horizontal direction, and the vertical lines are arranged at intervals in the vertical direction. A ceiling board is installed between two adjacent horizontal lines or vertical lines. The trimming line is installed around the walls. A trimming ceiling board is installed between the trimming line and the adjacent horizontal line or vertical line. The ceiling board is installed on the hook support feet of the horizontal line through the clamping hooks at both ends. A filling board is installed between the ceiling board and the first limit stop frame. A ceiling support bracket and a third limit stop frame are provided on the trimming line. A filling board is installed between the trimming ceiling board and the third limit stop frame. This ceiling installation structure has the advantages of simpler installation and firm installation, but still cannot solve the above problems. Summary of the Invention

[0005] The present invention is to overcome the defects that the edge trimming structure of the existing ceiling has low installation efficiency, large disassembly difficulty, and insufficient aesthetics, and provides a new type of hanging and assembled bathroom ceiling and its installation method to overcome the above defects.

[0006] To achieve the above invention purpose, the present invention is realized through the following technical solutions:

[0007] A new type of hanging and assembled bathroom ceiling, comprising:

[0008] A hanging piece, with a receiving cavity provided at its upper end and a connecting portion provided at its lower end. The connecting portion includes a clamping cavity, and a through groove penetrating the connecting portion is provided at the bottom of the clamping cavity;

[0009] A concave-shaped keel, which is arranged inside the receiving cavity;

[0010] An I-shaped piece, including an upper clamping edge at its upper end and a lower clamping edge at its lower end, which are fixedly connected by a connecting column between them. The clamping edge is clamped and fixed with the clamping cavity of the connecting portion at the lower end of the hanging piece. Two clamping grooves are symmetrically arranged in the area between the upper clamping edge and the lower clamping edge along the connecting column, and a decorative panel is clamped in the clamping grooves at the lower ends of two adjacent I-shaped pieces;

[0011] A finishing strip, with a connecting plate provided at its upper end for clamping with the clamping cavity at the lower end of the hanging piece. A finishing line is provided downward at the center of the connecting plate, and the finishing line is closely attached to the wall.

[0012] The hanging structure in the present invention is a single-layer keel structure. Compared with the traditional double-layer keel structure, it can effectively reduce the floor height occupation. The entire occupied floor height is less than 40 mm, greatly reducing the occupied floor height, significantly increasing the height of the ceiling after assembly, thereby effectively increasing the height of the room and greatly alleviating the sense of space depression.

[0013] At the same time, a connecting portion is provided below the hanging piece. By clamping the clamping cavity in the connecting portion with the upper clamping edge at the upper end of the I-shaped piece, the connection between the I-shaped piece and the hanging piece can be effectively simplified. The decorative panel and the I-shaped piece also adopt a clamping connection method. Compared with the traditional screw connection, this method in the present invention can effectively improve the installation efficiency of the ceiling and reduce the difficulty of subsequent disassembly, avoiding the problem that the board is prone to deformation due to nail driving. Thus, the safety can be effectively improved without affecting the aesthetics of the overall ceiling.

[0014] At the same time, in the finishing structure described in the present invention, the finishing strip is fixedly connected to the hanging piece by a clamping method, and there is no need to use methods such as nail driving to connect with the wall and the hanging piece during the installation process, thereby effectively reducing the installation difficulty of the finishing strip. Since the clamping connection method will not cause deformation of the finishing strip, its aesthetics and safety can be guaranteed after installation.

[0015] Preferably, a notch is provided on one side of the receiving cavity, and a stress support plate is provided above the notch.

[0016] Preferably, one side of the cross-section of the concave keel includes a bent edge that abuts against the stress support plate. The upper end of the bent edge abuts against the stress support plate of the accommodation cavity, and the lower end of the bent edge abuts against the bottom of the accommodation cavity and extends towards the outside of the notch.

[0017] On the other side of the concave keel, there is a straight edge that abuts against the other side of the accommodation cavity, and there is a gap between the bottom of the straight edge and the bottom of the accommodation cavity.

[0018] In addition, for the keel in the prior art, when it cooperates with the hanger, usually only the bottom of it contacts the hanger, so as to disperse the self-weight of the keel and the components located below the keel through the bottom of the keel. This method requires a relatively large amount of material. The concave keel in the present invention adopts a special structural design. First, only the lower end of the bent edge at the lowest end of the concave keel contacts the bottom of the accommodation cavity. Therefore, during the actual installation process, the keel will tilt towards the straight-edge side. Since the straight-edge side abuts against the accommodation cavity, the originally unloaded straight edge plays the role of a support edge. Coupled with the upper end of the bent edge abutting against the stress support plate, a three-point support effect is finally formed, dispersing the force on the keel, thereby increasing the sectional moment of inertia of the concave main keel and improving the stability of the keel structure.

[0019] Moreover, compared with the closed rectangular structure, this structure effectively reduces the material consumption of the keel and makes the keel lighter in mass.

[0020] In the present invention, since the concave keel has a tendency to rotate in the direction opposite to the bent edge, there is a frictional force towards the inside of the notch at the bottom of the bent edge. If the bottom of the bent edge is arranged towards the inside of the notch at this time, the lower end of the bent edge is prone to bending deformation. Therefore, by arranging the lower end of the bent edge towards the outside of the notch, the structural stability of the bent edge can be effectively improved.

[0021] Preferably, a groove is further provided at the center of the concave keel;

[0022] A first stress-bearing area is formed between the groove and the bent edge;

[0023] A second stress-bearing area is formed between the groove and the straight edge;

[0024] The second stress-bearing area is a closed rectangular block;

[0025] The straight edge is arranged at the outermost side of the rectangular block, and the bottom of the groove is located at the center of the rectangular block.

[0026] A groove is also provided at the center of the concave keel in the invention, and there are two purposes. Firstly, through the design of the groove, the concave keel can be divided into a first stress area and a second stress area, thereby separating the forces received on the left and right sides of the concave keel, enabling the first stress area and the second stress area to bear the pressure separately, thus improving the structural stability. At the same time, since the side of the groove provides buffering and strengthening for the bent edge and the straight edge, the individual load-bearing capacity of the two areas is greatly improved. Secondly, the design of the groove can facilitate the up and down tightening operation of the expansion screw, provide corresponding expansion space for the expansion screw, and will not damage the concave keel itself during the process of screwing the screw.

[0027] In addition, due to the special structure of the concave keel of the present invention, the straight edge in the second stress area is subjected to greater force. Therefore, setting the second stress area as a rectangular block can effectively improve the structural stability of the second stress area, so that no deformation problem will occur when the second stress area is stressed.

[0028] At the same time, when the rectangular block is subjected to the pressure transmitted from the side of the hanging piece, there is a risk of rotational deformation along the connection point between the bottom of the groove and the rectangular block. Therefore, locating the bottom of the groove at the center of the rectangular block can balance the stress of the rectangular block, make the upper and lower moments the same, and reduce the deformation risk.

[0029] Preferably, a stepped support edge is provided at the end of the upper clamping edge, and the support edge is inserted into the inside of the clamping cavity.

[0030] Preferably, an arc-shaped clamping head is provided at the end of the lower clamping edge;

[0031] A plurality of reinforcing ribs are protruded outward from the middle of the connecting column.

[0032] An arc-shaped clamping head is provided at the end of the lower clamping edge in the present invention. When it is clamped with the decorative panel, only the arc-shaped clamping head contacts the decorative panel, so that the pressure at the connection between the decorative panel and the arc-shaped clamping head is relatively large, making the connection stability between the two better.

[0033] And the middle part of the connecting column is provided with reinforcing ribs, which can effectively improve the mechanical strength of the connecting column, thereby enhancing the bearing capacity of the I-shaped part.

[0034] Preferably, an annular groove is provided at the center of the side of the decorative panel;

[0035] The lower clamping edge at the lower end of the I-shaped part is clamped and adapted to the annular groove, so that the upper end surface of the annular groove is embedded into the inside of the clamping groove between the upper end surfaces of the decorative panels.

[0036] Preferably, a support member with a triangular cross-section is provided on the side of the edge line away from the wall, and a second clamping groove for clamping the decorative panel is formed between the support member and the connecting plate.

[0037] The present invention provides a support member on the side of the trim line away from the wall, so that it can be used to support the decorative panel, so that the gap between the decorative panel and the trim line can be effectively covered, effectively improving the aesthetics. At the same time, the cross section of the support member is set to be triangular, which can effectively improve the mechanical stability of the support member after being pressed down by the decorative panel.

[0038] Preferably, a C-shaped connector with a side opening is fixedly connected to the top of the wall, and a placement cavity for setting up a concave keel is provided inside the C-shaped connector, and the bottom of the placement cavity is fixedly connected to the wall.

[0039] A novel method for installing a hanging assembled bathroom ceiling comprises the following steps:

[0040] (1) A groove is made at the top of the wall, and the C-shaped connector is fixedly embedded in the groove at the top of the wall so that the C-shaped connector is fixed to the wall;

[0041] (2) several hangers are mounted on the concave keel, and there is one hanger on each side of the concave keel. Several hangers are taken and the concave keel is inserted into the accommodating cavity of the hangers so that the lower end of the bent edge of the concave keel extends toward the outside of the notch;

[0042] (3) Insert the concave keel into the second clamping groove of the C-shaped connector;

[0043] (4) Fix the hanging rods at intervals on the top of the hanging parts, connect the hanging rods to the roof, and thus hang the concave keel and the hanging parts on the roof;

[0044] (5) Insert the I-shaped piece and the upper clamping edge of the upper end of the edge trim into the clamping cavity, so that the connecting plate at the upper end of the edge trim is plugged and fixed into the clamping cavity, and the edge trim is closely attached to the wall;

[0045] (6) Insert the decorative panel into the slot of the adjacent I-shaped piece to complete the installation of the ceiling.

[0046] Therefore, the present invention has the following beneficial effects:

[0047] (1) The present invention can effectively reduce the floor height occupied by the keel through the design of a single-layer hanging keel, thereby effectively increasing the indoor height and greatly alleviating the oppressiveness of the space.

[0048] (2) Through the unique keel structure design of the present invention, the overall structure of the keel can be used to bear the weight of the keel itself and the components below, dispersing the stress on the keel, thereby increasing the sectional moment of inertia of the concave main keel and improving the stability of the keel structure.

[0049] (3) Simplify the connection and installation of the components below the keel, with strong versatility and convenient installation, greatly improving the installation efficiency, thus making the assembly simpler. At the same time, adjustable splicing of large-space flat ceilings is achieved.

[0050] (4) In the edge trimming structure described in the present invention, the edge trimming line is fixedly connected to the hanging part by means of snap connection, and there is no need to use methods such as nailing to connect with the wall and the hanging part during the installation process, thereby effectively reducing the installation difficulty of the edge trimming line.

[0051] (5) Since the snap connection method will not cause deformation of the edge trimming line, its aesthetics and safety can be guaranteed after the installation is completed. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0065] The present invention will be further described below with reference to the accompanying drawings of the specification and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are usually only a part of the embodiments of the present invention, rather than all the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention shall fall within the protection scope of the present invention.

[0066] Embodiment

[0067] As Figures 1 - 12 shown, a new type of hanging and assembled bathroom ceiling includes a concave keel 10 and a plurality of hanging parts 20 that cooperate with the concave keel 10. An I-shaped part 30 is fixedly connected and arranged below the hanging part 20. A decorative panel 40 is inserted and connected between the bottoms of adjacent I-shaped parts 30. An edge trimming structure is further arranged below the end of the concave keel 10, which includes edge trimming lines 50 located at the left and right ends of the concave keel 10, and the edge trimming lines 50 are closely attached to the wall body 60.

[0068] Wherein: the hanging part 20 is in a "6" shape, and an accommodating cavity 21 for accommodating the concave keel 10 is arranged at its upper end. The accommodating cavity 21 is generally rectangular, and a notch 22 is arranged at one end of its side. Correspondingly, the part of the hanging part 20 above the notch 22 forms a stress support plate 23.

[0069] The concave keel 10 is generally in a concave shape, and a horizontal edge is missing at its lower end. A downward groove 13 is arranged at its center. Therefore, a first stress area 14 is formed on one side of the groove 13, and a second stress area 15 is formed on the other side of the groove.

[0070] Wherein, a bending edge 11 is arranged on the side of the first stress area 14 away from the groove 13. The upper end of the bending edge 11 is a vertical edge, and the upper end of this vertical edge is in contact with the stress support plate 23 of the accommodation cavity 21, so as to play a role in limiting the concave keel 10. The lower end of the bending edge 11 is a horizontal edge, the lower end of which is in contact with the bottom of the accommodation cavity 21, and its end extends to the outside of the notch 22 and to the outside of the hanging part 20.

[0071] The second stress area 15 is a rectangular closed rectangular block 16. Because of the special structure of the concave keel 10 of the present invention, the stress at the second stress area 15 is relatively large. Therefore, setting the second stress area 15 as the rectangular block 16 can effectively improve the structural stability of the second stress area 15, so that the second stress area 15 will not deform when stressed.

[0072] In addition, in order to ensure the structural stability of the second stress area 15, the present invention also connects the bottom of the groove 13 to the center of the rectangular block 16, so as to balance the stress of the rectangular block, make the upper and lower moments the same, and reduce the deformation risk.

[0073] The outermost side of the second stress area 15 in contact with the accommodation cavity 21 is a straight edge 12, and there is a certain gap between the rectangular block 16 and the bottom of the accommodation cavity 21.

[0074] The concave keel 10 in the present invention adopts a special structural design. First, only the lower end of the bending edge 11 at the lowermost end of the concave keel 10 is in contact with the bottom of the accommodation cavity 21. Therefore, during the actual installation process, the concave keel 10 has a tendency to tilt towards the straight edge 12. However, since the straight edge 12 side is in contact with the accommodation cavity 21, the originally non-stressed straight edge 21 plays the role of a support edge. Coupled with the upper end of the bending edge 11 being in contact with the stress support plate 23, a three-point co-support effect of the bottom of the bending edge 11, the top of the bending edge 11, and the straight edge 12 is finally formed, thereby dispersing the stress of the concave keel 10, changing the structure that was stressed on one side originally into an overall stressed structure, thereby increasing the section moment of inertia of the concave keel 10 and improving the structural stability of the concave main keel 10.

[0075] In addition, a connecting portion 24 capable of connecting other connecting members is provided below the accommodating cavity 21 of the hanging member 20. The connecting portion 24 includes a clamping cavity 25, and a through groove 26 penetrating the connecting portion 24 is provided at the bottom of the clamping cavity 25. Therefore, through the arrangement of the clamping cavity 25 and the through groove 26, the connection and installation of the components below the keel can be simplified, with strong versatility, convenient installation, greatly improving the installation efficiency, and thus making the assembly simpler. At the same time, the adjustable splicing of the large-space flat ceiling is realized.

[0076] In some preferred embodiments, strip-shaped grooves 27 communicating with the clamping cavity 25 may be provided on the left and right sides of the connecting portion 24, so as to effectively reduce the self-weight of the hanging member on the premise of not affecting the bearing capacity of the hanging member 20 and improve the structural stability.

[0077] In order to hang the concave keel 10 and the hanging member 20 on the roof, a hanging rod 28 is further provided on some hanging members 20. In some preferred solutions, the hanging rod 28 can be connected above the hanging member 20 by fixing means such as expansion screws. The previous design of the groove of the hanging member 20 can facilitate the up and down tightening operation of the expansion screw, provide corresponding expansion space for the expansion screw, and will not damage the concave keel 10 itself during the process of screwing the screw.

[0078] The I-shaped member 30 is in the shape of "I", and includes an upper clamping edge 31 at its upper end and a lower clamping edge 32 at its lower end. The two are fixedly connected by a connecting column 33, and two clamping grooves 34 adapted to the decorative panel 40 are symmetrically arranged in the region between the upper clamping edge 31 and the lower clamping edge 32 along the connecting column 33.

[0079] Wherein, a stepped support edge 35 is provided at the end of the upper clamping edge 31, and this support edge 35 is inserted into the clamping cavity 25, so that the I-shaped member 30 is suspended at the connecting portion 24 at the lower end of the hanging member 20. When the I-shaped member 30 is connected to the connecting portion 24, only the support edge 35 of the upper clamping edge 31 needs to be inserted into the clamping cavity 25, and the connecting column 33 passes through the through groove 26, so as to realize the clamping between the two, and the I-shaped member 30 is suspended below the hanging member 20.

[0080] An arc-shaped clamping head 36 is provided at the end of the lower clamping edge 32 of the I-shaped member 30. Therefore, when the decorative panel 40 is inserted into the clamping groove 34, the lower clamping edge 32 is only fixed to the decorative panel 40 through the arc-shaped clamping head 36, so that the pressure at the connection between the decorative panel 40 and the arc-shaped clamping head 36 is relatively large, making the connection stability between the two better.

[0081] A plurality of reinforcing ribs 37 are protruded outward from the middle of the connecting column 33, which can effectively improve the mechanical strength of the connecting column 33, thereby enhancing the bearing capacity of the I-shaped member.

[0082] An annular groove 41 is provided at the center of the side of the decorative panel 40, so that the lower clamping edge 32 of the lower end of the I-shaped member 30 is clamped and adapted to the annular groove 41, so that the upper end surface of the annular groove 41 and the upper end surface of the decorative panel 40 are embedded in the clamping groove 34.

[0083] The trimming line 50 includes a connecting plate 51 at its upper end, and the connecting plate 51 is used to be clipped with the clipping cavity 25 at the lower end of the hanger 20. A trimming line 52 is arranged downward at the center of the connecting plate 51, and the trimming line 52 is closely attached to the wall 60. The trimming line 50 in the trimming structure of the present invention is fixedly connected with the hanger by clipping, and it is not necessary to connect with the wall 60 and the hanger 20 by nailing during the installation process, thereby effectively reducing the installation difficulty of the trimming line 50. In addition, due to the clipping connection method, the trimming line 50 will not be deformed, and its aesthetics and safety can be guaranteed after the installation.

[0084] A support member 53 is provided on the side of the trim line 52 away from the wall 60, and a second snap-in groove 54 for snapping the decorative panel is formed between the support member 53 and the connecting plate 51. The present invention provides a support member 53 on the side of the trim line away from the wall 60, so it can be used to support the decorative panel, so that the gap between the decorative panel and the trim line 50 can be effectively covered, effectively improving the aesthetics. Secondly, in order to improve the mechanical stability of the support member 53 after being pressed down by the decorative panel, the cross section of the support member 53 can be set to a triangle in some preferred embodiments.

[0085] In addition, in order to ensure that the concave keel 10 can be stably fixed on the wall 60, a C-shaped connecting piece 61 with a side opening is fixedly connected to the top of the wall 60, and a placement cavity 62 for erecting the concave keel 10 is provided inside the C-shaped connecting piece 61, and the bottom of the placement cavity 62 is fixedly connected to the wall 60.

[0090] 2 Set a number of hanging parts 20 on the concave keel 10, and ensure that there is one hanging part 20 on each of the left and right sides of the concave keel 10. Take a number of hanging parts 20, and insert the concave keel 10 into the receiving cavity 21 of the hanging parts 20, so that the lower end of the bending edge 11 of the concave keel 10 extends towards the outside of the notch 22;

[0091] 3 Insert the concave keel 10 into the second clamping groove 54 of the C-shaped connecting piece 61;

[0092] 4 Fix the hanging rods 28 at intervals on the top of the hanging parts 20, and connect the hanging rods 28 to the roof, so as to hang the concave keel 10 and the hanging parts 20 on the roof;
