Description

Technical Field

[0001] The present invention relates to the technical field of assembled suspended ceilings, and in particular to a snap-in type bathroom suspended ceiling and its installation method. Background Art

[0002] Ceiling decoration is a commonly used decoration method in interior design, which can increase the sense of hierarchy of the indoor space and play a role in beautifying the decoration. At present, the decoration industry is developing towards the direction of industrialization, modularization, and assembled installation. As the name implies, assembled decoration means that each component required for decoration is produced and completed in the factory, and then transported to the decoration site for combined installation, eliminating the traditional operations of measuring and cutting each component at the decoration site. The construction is simpler and more convenient. Adopting assembled installation in the kitchen and bathroom suspended ceiling process can greatly improve the construction efficiency at the decoration site, and the construction site is cleaner and more beautiful, without generating too much decoration material waste. It is a more environmentally friendly decoration construction form.

[0003] In today's decoration styles, lamps are often installed inside the suspended ceiling to improve the aesthetics. The lamps often use long strip-shaped light belts. To facilitate the placement of the light belts and effectively scatter the light, a return light slot needs to be opened inside the suspended ceiling.

DETAILED DESCRIPTION

[0030] The following are specific implementations of the present invention, and in conjunction with the accompanying drawings, the technical solution of the present invention is further described, but the present invention is not limited to these embodiments.

[0031] A hook-type bathroom ceiling, such as Figure 1 and Figure 2 As shown, it is used in an installation space having a pair of opposite first side walls and a pair of opposite second side walls, and the first side walls and the second side walls are substantially perpendicular. The first side walls and the second side walls are collectively referred to as side walls, and a wall panel 3 is installed on each of the side walls. In this embodiment, the first side walls and the second side walls are not shown in the figure. Figure 1 In the figure, the left and right wall panels 3 are both wall panels arranged on the second side wall; Figure 2 In the figure, the front and rear wall panels 3 are both wall panels arranged on the first side wall.

[0032] The wall panel 3 can be connected to the side wall in any way, such as gluing, dry hanging, screw connection, etc. In this embodiment, a wall panel 3 made of a material with a certain support hardness is selected, such as a gypsum board, thickened ceramic tile, etc.; and the wall panel 3 is installed on the side wall by screws, gluing and auxiliary dry hanging. For example, a profile with a groove structure is first screwed into the side wall, and a profile with a plug structure is screwed into the back of the wall panel 3. The installation is achieved through the cooperation of the groove and the plug. At the same time, an adhesive can be applied between the groove and the plug to further improve the strength; in addition, a profile for fixing the bottom end of the wall panel 3 can also be set on the ground of the installation space, such as a U-shaped profile, the bottom plate of which is screwed into the ground, and the bottom end of the wall panel 3 is inserted into its U-shaped groove. The height of the wall panel 3 does not exceed the height of the side wall, and the specific height of the wall panel 3 is set accordingly according to the installation height of the subsequent ceiling and the backlight trough.

[0033] The suspended ceiling is mainly an integral structure composed of several suspended ceiling panels, installed on the top of the installation space. The suspended ceiling panels and the top wall are connected by keels 2. Figure 2As shown, the longitudinal direction of the keel 2 is parallel to the longitudinal direction of the ceiling board. The number of keels 2 provided on the back of each ceiling board is not limited, and one or two are sufficient. The structure of the keel 2 is not restricted, and it can be square tube type, I-shaped, or channel-shaped. In this embodiment, a channel-shaped keel is adopted, such as Figure 2 and Figure 3 shown, that is, the keel 2 includes two flanging parts that are respectively parallel to the ceiling board and connected by screws or welding, and vertical parts are respectively connected to the two flanging parts. The two vertical parts are connected through the top. The flanging parts, vertical parts, and top are usually integrally formed. This channel-shaped keel is generally hook-connected to the square tube installed on the top wall through a hook member. For example, an S-shaped hook member can be used. One end of it is inserted between the flanging part and the ceiling board, and then the flanging part 21, the hook member, and the ceiling board are fixedly connected. The other end of it is lapped on the square tube. The splicing method between adjacent ceiling boards is not restricted. It can be such that the sides of the ceiling boards directly abut against each other; or a splicing structure can be used for connection. For example, a groove is provided on the side of the ceiling board, and the splicing structure can be an inverted T-shaped profile. The two horizontal ends of it are respectively inserted into the grooves of two adjacent ordinary ceiling boards, and a lapping board or the like is provided at one vertical end of it to be connected to the square tube provided on the top wall.

[0034] Since the area of the ceiling board and the actual area of the installation space cannot be completely matched, there will be a gap between the overall ceiling structure and the side wall. At this time, the end part of the overall ceiling structure needs to be connected to the side wall through the edge trim member 4 and the gap between the two needs to be filled. At the same time, in some decoration schemes, it is necessary to install lamps on the back of the ceiling and make the light leak out through reflection and scattering. Therefore, a backlight trough member 5 is also required. The backlight trough member 5 is generally also arranged between the end part of the overall ceiling structure and the side wall and has an edge trimming effect. In this application, since the installation structure between the overall ceiling structure and the side wall is mainly discussed, for the convenience of description, this overall structure composed of several ceiling boards spliced together is denoted as the overall ceiling board 1. In the overall ceiling board 1, a keel 2 is provided on each ceiling board; overall, it is equivalent to several parallel keels 2 being provided on the overall ceiling board 1.

[0035] There are gaps between the four end parts of the overall ceiling board 1 and the four side walls respectively, and edge trimming is required respectively. At the same time, considering the application of lamps, a backlight trough member 5 can be provided between one of the four end parts and the side wall, and ordinary edge trim members 4 can be provided between the other three end parts and the side wall; or a backlight trough member 5 can be provided between a pair of opposite end parts and the side wall respectively, and ordinary edge trim members 4 can be provided between the other pair of opposite end parts and the side wall respectively. The end part where the backlight trough member 5 is provided between it and the side wall is denoted as the lamp end 12, and the end part where the edge trim member 4 is provided between it and the side wall is denoted as the edge trim end 11.

[0036] In this embodiment, the installation method of one backlight trough member 5 and three edge trim members 4 is used for illustration, such asFigure 1 and Figure 2 As shown, the edge-closing end 11 is connected to the first side wall or the second side wall through the edge-closing member 4, and the lamp end 12 is connected to the second side wall through the backlight trough member 5. During installation, first install the edge-closing member 4 and the backlight trough member 5 on the side wall respectively, and then lift the ceiling board.

[0037] Regarding the edge-closing member 4, first look at the installation of the edge-closing member 4 between the edge-closing end 11 and the second side wall. As Figure 4As shown in the figure, the edge trim member 4 is an integrally formed profile, including a wall panel connection structure connected to the wall panel 3 and a ceiling panel connection structure connected to the edge connection end 11. The wall panel connection structure is in an inverted U shape, including a horizontal top connection part 45, and a back connection part 44 and a front connection part 46 vertically arranged at both ends of the top connection part 45 respectively. The ceiling panel connection structure is connected to the front connection part 46. During installation, the wall panel connection structure is inserted into the top end of the wall panel 3 through its inverted U-shaped groove. The length of the top connection part 45 can be designed to be basically the same as the thickness of the wall panel 3, so that after the wall panel connection structure is installed on the wall panel 3, the back connection part 44, the top connection part 45, and the front connection part 46 are respectively in contact with the back surface, the top surface, and the front surface of the wall panel 3. Since a ceiling panel that needs to bear a certain gravity will be installed on the front connection part 46, the ceiling panel connection structure is likely to drive the front connection part 46 to bend towards the wall panel 3 under the action of gravity. Therefore, in this embodiment, the length of the top connection part 45 is designed to be greater than the thickness of the wall panel 3, and a tightening block 47 is arranged on the side of the front connection part 46 close to the wall panel 3, so that after the wall panel connection structure is installed on the wall panel 3, the back connection part 44 and the top connection part 45 are respectively in contact with the back surface and the top surface of the wall panel 3, but there is a gap between the front connection part 46 and the front surface of the wall panel 3, and the free end of the tightening block 47 is in contact with the front surface of the wall panel 3. Then, when the ceiling panel connection structure drives the front connection part 46 to have a tendency to bend towards the wall panel 3 under the action of gravity, it will drive the free end of the tightening block 47 to move inwards and upwards, and since the free end of the tightening block 47 is already in contact with the wall panel 3, this bending tendency is restricted by the stopping and frictional force of the wall panel 3, improving the stability of the edge trim member structure. Therefore, preferably, the free end surface of the tightening block 47 is provided with patterns for increasing friction. Based on this, when installing this wall panel connection structure, first apply a layer of structural adhesive on the back surface of the wall panel 3 or / and the back connection part 44, and the top surface of the wall panel 3 or / and the top connection part 45, then move the wall panel connection structure downwards so that the back connection part 44 is inserted into the gap between the wall panel 3 and the second side wall; continue to move the edge trim member downwards so that the top connection part 45 is in contact with the top surface of the wall panel 3, then push the edge trim member inwards so that the end of the tightening block 47 is in close contact with the front surface of the wall panel 3; finally, drive a screw into the front connection part 46, and the tail of the screw is inserted into the wall panel 3. Preferably, a longer screw can be used so that the tail of the screw can also be inserted into the back connection part 44 or even into the second side wall. The structural adhesive filled on the back surface of the wall panel 3 or / and the back connection part 44 can be more to make up for the gap between the wall panel 3 and the back connection part 44. In addition, at this time, if the gap between the back connection part 44 and the second side wall is large, it can also be filled with structural adhesive.

[0038] The ceiling panel connection structure is Z-shaped, including a limiting portion 41 parallel to the side surface of the edge-receiving end 11, a receiving portion 42 and a reinforcing portion 43 vertically arranged at both ends of the limiting portion 41 respectively. The other end of the reinforcing portion 43 is vertically connected to the above-mentioned positive connection portion 46. Note that it is necessary to control the horizontal plane where the abutting block 47 is located to be higher than the horizontal plane where the reinforcing portion 43 is located. Otherwise, before the positive connection portion 46 is bent in the ceiling panel connection structure, the connection between the reinforcing portion 43 and the positive connection portion 46 may be bent or broken, and the above-mentioned structural strengthening effect cannot be achieved.

[0039] When installing the ceiling panel with the installation end serving as the edge-receiving end 11, it is first necessary to lengthen the keel 2 on the ground, that is, drive the wood-plastic block into its back surface. One end of the wood-plastic block abuts against the end of the keel 2, and the other end protrudes from the end surface of the edge-receiving end 11. When lengthening the keel 2, the length of the reinforcing portion 43 can be measured first to control the length of the part of the keel 2 protruding from the edge-receiving end 11, that is, the length of the protruding part is basically the same as the length of the reinforcing portion 43. Then in the direction of Figure 4 , the ceiling panel is lifted obliquely as a whole with the left side on top and the right side on the bottom. After being lifted through the gap between the left edge-receiving member 4 and the right ceiling panel, it is rotated to the horizontal, and then the ceiling panel is lowered so that the edge-receiving end 11 overlaps on the receiving portion 42, and the protruding part overlaps on the reinforcing portion 43; then drive a screw into the reinforcing portion 43 so that the tail of the screw passes through the reinforcing portion 43 and the protruding part in sequence to complete the fixation. The nail holes can be set on the reinforcing portion 43 in advance for easy positioning.

[0040] After the above installation is completed, based on the structure of the edge-receiving member 4, a two-level trapezoidal structure is presented between the second side wall and the ceiling. At this time, a support plate 31 can be added to the front surface of the wall panel 3. The top surface of the support plate 31 abuts against the abutting block 47, and the front surface abuts against the side of the positive connection portion 46 close to the wall panel 3 to enclose a part of the stepped structure and avoid dust accumulation here, which is difficult to clean; at the same time, the top end of the support plate 31 is inserted and abutted between the abutting block 47 and the positive connection portion 46, playing a certain role in structural strengthening; in addition, the connection between the support plate 31 and the wall panel 3 can be designed as a detachable connection, such as adhesive connection, and its structural style can be freely changed according to the requirements of the user, improving the practicability.

[0041] Then look at the installation of the edge-receiving member 4 between the edge-receiving end 11 and the first side wall, as Figure 2As shown, the structure and installation method of the edge trim member 4 are basically the same as above, but at this time only the edge trim end 11 is lapped on its receiving portion 42. Therefore, a reinforcing block can also be added to the back of the overall ceiling board 1. One end of the reinforcing block protrudes from one end in the width direction of the ceiling board, and the part of the reinforcing block protruding from the ceiling board is lapped on the reinforcing portion 43 of the edge trim member 4 provided on the first side wall. After the lapping is completed, screws are still used to fix from bottom to top at the reinforcing portion 43. Further, extend the other end of the reinforcing block so that the reinforcing block is lapped on the folded edge portion of the adjacent keel 2, and it is pressed on the keel 2 to improve the installation strength between the ceiling board and the keel 2. Considering that the folded edge portion has a certain thickness, a semi-groove for the folded edge portion to insert is provided at the end of the reinforcing block.

[0042] For the backlight trough member 5, as Figure 5 shown, the backlight trough member 5 includes a trough profile and a fixing pipe 53 for supporting the trough profile. The two ends in the length direction of the fixing pipe 53 are respectively connected to the first side wall, and the connection method is not limited. Preferably, L-shaped fixing members are first provided on the two first side walls respectively. The vertical plate of the fixing member is connected to the first side wall through expansion bolts, and the horizontal plate of the fixing member is used for the end of the fixing pipe 53 to lap. After the fixing pipe 53 is lapped on the horizontal plate, it is preferably further reinforced by welding, screw connection and other methods. Further, an inclined reinforcing plate is provided between the bottom surface of the horizontal plate and the first side wall to form a triangular support structure to prevent the fixing member from deforming under force.

[0043] The trough profile is L-shaped and includes a vertical heightening plate 51 and a horizontal backlight plate 52. The length of the backlight plate 52 needs to be greater than the distance between the side of the lamp end 12 and the second side wall. The heightening plate 51 and the backlight plate 52 can be integrally formed, or as Figure 5 shown, in this embodiment, first cut one end of the heightening plate 51 and one end of a horizontal plate at 45°, then vertically splice the two, and insert a triangular block at the angle between the heightening plate 51 and the horizontal plate. Use a screw to sequentially pass through the triangular block and the heightening plate 51, and at the same time use another screw to sequentially pass through the triangular block and the horizontal plate to complete the connection between the heightening plate 51 and the horizontal plate; then stick the backlight plate 52 tightly on the horizontal plate, and then use screws to sequentially pass through the backlight plate 52, the horizontal plate and the triangular block, so as to complete the connection between the heightening plate 51 and the backlight plate 52.

[0044] Among them, the heightening plate 51 is also connected to the above-mentioned fixing pipe 53, and the connection method is not limited. For example, in this embodiment, as Figure 2 shown, the heightening plate 51 is connected to the fixing pipe 53 through a plurality of L-shaped angle codes. The vertical plate of the angle code is parallel and connected to the heightening plate 51, and the horizontal plate is parallel and connected to the top surface of the fixing pipe 53. The connection method can be screw connection or welding.

[0045] When installing the light slot profile, first complete the connection of the raised plate 51 and the light return plate 52 on the ground, as well as the connection of the fixed pipe 53 to the raised plate 51. At the same time, install the fixing parts of the fixed pipe 53 at the corresponding positions on the first side wall. Then lift the whole unit so that the end of the light return plate 52 overlaps the top surface of the wall panel 3 on the second side wall, and both ends of the fixed pipe 53 overlap on the horizontal plates of the two fixing parts. After adjusting the position, the light return plate 52 and the top surface of the wall panel 3 can be fixed by gluing, screws, etc., and the fixed pipe 53 and the fixing parts are fixed by screws, welding, etc. At this time, it can be seen that an inverted U-shaped light return slot is formed between the raised plate 51, the light return plate 52 and the wall panel 3.

[0046] When installing the ceiling board whose end is used as the lamp end 12, first complete the installation of the ceiling board and the keel 2 on the ground, and pay attention to controlling the installation position of the keel 2. As Figure 5 shown, the end of the keel 2 does not exceed the side surface of the ceiling board, so that there is a blank part on the back of the lamp end 12. At the same time, add a hook 6 to the part of the keel 2 close to the lamp end 12. As Figure 2 and Figure 6 shown, the hook 6 includes two keel connection parts 61, and the two keel connection parts 61 are respectively parallel to and connected to the two vertical parts of the keel 2; the hook 6 also includes a lapping part 62 for lapping on the top surface of the fixed pipe 53, and the above two keel connection parts 61 are respectively arranged at both ends of the lapping part. After the ceiling board, the keel 2 and the hook 6 are installed, lift them up so that the lapping part of the hook 6 laps on the fixed pipe 53. In order to improve the lapping strength, the hook 6 also includes an insertion part 63 for inserting between the fixed pipe 53 and the raised plate 51. To achieve this insertion, a corresponding gap needs to be left between the raised plate 51 and the fixed pipe 53 during the installation process. At the same time, for the convenience of installation, when the insertion part 63 is provided, the height of the raised plate 51 needs to be reduced to avoid blocking the insertion of the insertion part 63. At this time, after the ceiling board is installed, there is a gap between the blank part on the back of the lamp end 12 and the bottom end of the raised plate 51. At this time, an L-shaped angle code can be added, and the upper end of its vertical plate is attached to and connected to the raised plate 51, and the horizontal plate is attached to and connected to the blank part of the ceiling board.

[0047] After completing the above installation, a part of the lamp end 12 is located in the light return slot, which is called the installation part. Install the lamp 13 on the back of this installation part, and the light return can be realized. The lamp 13 is preferably installed in a detachable manner such as gluing, which is convenient for subsequent maintenance and replacement. At the same time, in order to prevent the rough edge of the lamp end 12 from hurting the operator, a protective cover is also provided on it to wrap the edge of the lamp end 12.

[0048] Based on the above-mentioned snap-on bathroom ceiling, its installation method includes the following steps:

[0049] S1. Install the edge trim member 4 on the first side wall or the second side wall, and install the backlight trough member 5 on the second side wall.

[0050] S2. Lift up the ceiling board with the end part serving as the edge trimming end 11, and lap the protruding part of the keel 2 on the reinforcement part 43; lift up the ceiling board with the end part serving as the lamp end 12, so that the hook member 6 is hooked on the fixed pipe 53.

[0051] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
