Description

Technical Field

[0001] The present invention relates to the technical field of assembled suspended ceilings, and particularly relates to a wall-top heightening structure and an installation method thereof. Background Art

[0002] Suspended 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 in the factory and then transported to the decoration site for combined installation, eliminating the traditional operations of measuring and cutting each component on 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 of 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 an assembled suspended ceiling with a backlight trough structure, in order to achieve the backlight effect, lamps are usually arranged on the back of the end of the suspended ceiling board. At this time, in order to assist in the connection of the suspended ceiling board and not affect the lighting effect of the lamps, a profile with an installation height higher than that of the suspended ceiling board is usually provided. For example, the patent document with the publication number CN215211827U discloses such a multi-purpose backlight trough for a suspended ceiling, including a profile main body. One side of the top end face of the profile main body is provided with a first connection groove, one side of the profile main body is provided with a second connection groove, a downward vertical installation part is provided below the first connection groove, a first installation groove is provided below the second connection groove, a backlight trough is provided in the middle of the profile main body, and a lamp trough is provided at a position corresponding to the first installation groove on one side of the backlight trough. Since the installation height of the profile needs to be higher than that of the suspended ceiling board, in most assembled suspended ceiling structures, an installation method of reducing the installation height of the suspended ceiling board is selected, which results in the problems that the suspended ceiling occupies more floor height and the available height for indoor activities is lower. Summary of the Invention

[0004] The present invention aims to solve the above problems and provides a wall-top heightening structure and an installation method thereof to form a backlight trough without reducing the installation height of the suspended ceiling board.

[0005] The technical solution for the present invention to solve the problem is to first provide a wall top heightening structure, which is arranged between a low ceiling board and a side wall, and includes a high ceiling board. The horizontal plane where the high ceiling board is located is higher than the horizontal plane where the low ceiling board is located. The high ceiling board is connected to the top wall through high-position keels; one end of the high ceiling board is provided with a wall board heightening board, and the other end is provided with a ceiling heightening board; the wall board heightening board is flush with and connected to the wall board arranged on the side wall, and the ceiling heightening board is connected to the side of the low ceiling board close to the top wall; a backlight trough is formed among the ceiling heightening board, the high ceiling board and the wall board heightening board.

The reinforcing piece includes a first connecting part parallel to and connected to the low ceiling board and a second connecting part parallel to and connected to the ceiling heightening board.

[0010] As a preference of the present invention, the low ceiling board is connected to the top wall through a low-position keel. The low-position keel includes a folded edge part connected to the low ceiling board, and the ceiling heightening board is abutted against the folded edge part.

[0011] As a preference of the present invention, the low-position keel is in a shape of "J", and includes two folded edge parts. Vertical parts are respectively connected to the two folded edge parts, and the two vertical parts are connected through a connecting part.

Detailed Embodiments

[0026] The following are the detailed embodiments of the present invention. In combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0027] A wall top heightening structure, as Figure 2 shown, is used in an installation space having a pair of opposite first side walls, 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 wall panels 3 are installed on both side walls. In this embodiment, the first side walls and the second side walls are not shown in the figure. For the convenience of description, the Figure 1 right wall panel 3 in the figure is denoted as the wall panel provided on the second side wall. The wall panel 3 can be connected to the side wall in any manner, such as by gluing, dry hanging, screw connection, etc. In this embodiment, the wall panel 3 is a composite panel, including an inner panel having a certain support hardness, such as a gypsum board, a thickened ceramic tile, etc., and an outer panel serving as a decoration, such as a foamed board, etc. The inner panel and the outer panel are combined together by a detachable connection method, such as gluing, snap connection, etc., to form the wall panel 3. The wall panel 3 is installed on the side wall by means of screws, glue-assisted dry hanging. For example, first, screws are driven into a profile with a groove structure on the side wall, and screws are driven into a profile with a plug structure on the back of the wall panel 3, and the installation is achieved through the cooperation of the groove and the plug. At the same time, an adhesive can be coated 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 provided 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 according to the installation height of the subsequent ceiling and the heightening structure.

[0028] The ceiling is mainly an integral structure formed by splicing a plurality of ceiling panels and is installed on the top of the installation space. A heightening structure is provided between the ceiling integral structure and the side wall. According to the different relative heights, in this embodiment, the ceiling panels used to form the ceiling are called low-position ceiling panels 1, and the ceiling panels in the heightening structure are called high-position ceiling panels 51. The length of the high-position ceiling panel 51 is greater than the distance between the end of the low-position ceiling panel 1 and the wall panel 3.

[0029] The low-position ceiling panel 1 is connected to the top wall by a low-position keel 2, as Figure 2 shown. The length direction of the low-position keel 2 is parallel to the length direction of the low-position ceiling panel 1. The number of low-position keels 2 provided on the back of each ceiling panel is not limited, and one or two are sufficient. The structure of the low-position keel 2 is not limited, and it can be a square tube type, an I-shaped type, a channel-shaped type, etc. In this embodiment, a channel-shaped keel is used, as Figure 1As shown in the figure, the lower keel 2 includes two flanging parts 21 that are respectively parallel to the lower ceiling board 1 and are connected by screws or welding. Two vertical parts are respectively connected to the two flanging parts 21, and the two vertical parts are connected through the top. The flanging part, the vertical part, and the top are usually integrally formed. This type of C-shaped keel is generally hook-connected to the square tube installed on the top wall through a hooking part. For example, an S-shaped hooking part can be used. One end of it is inserted between the flanging part 21 and the lower ceiling board 1, and then the flanging part 21, the hooking part, and the lower ceiling board 1 are fixedly connected. The other end of it is lapped on the square tube. The splicing method between adjacent lower ceiling boards 1 is not restricted. It can be such that the sides of the lower ceiling boards 1 are directly abutted; it can also be connected by a splicing structure. For example, a groove is provided on the side of the lower ceiling board 1. The splicing structure can be an inverted T-shaped profile, and the two horizontal ends of it are respectively inserted into the grooves of adjacent two lower ceiling boards 1, and a lapping board or the like is provided at one vertical end of it to connect with the square tube provided on the top wall.

[0030] The upper ceiling board 51 is connected to the top wall by the upper keel 6. The structure and installation method of the upper keel 6 are the same as those of the lower keel 2. The only difference is that in the connection between the upper keel 6 and the top wall, the height of the hooking part used should be less than the height of the hooking part used for the lower keel 2 to ensure the flatness of the overall ceiling structure.

[0031] The heightening structure is for forming a backlight trough. As Figure 1 shown, a ceiling heightening board 52 is provided between the upper ceiling board 51 and the lower ceiling board 1, and a wallboard heightening board 53 is provided between the upper ceiling board 51 and the wallboard 3 of the second side wall. A U-shaped backlight trough is formed between the ceiling heightening board 52, the upper ceiling board 51, and the wallboard heightening board 53. In order to improve the backlight effect, a reflective film is provided on one side of the ceiling heightening board 52, the upper ceiling board 51, and the wallboard heightening board 53 close to the backlight trough.

[0032] The ceiling heightening board 52, the upper ceiling board 51, and the wallboard heightening board 53 can be integrally formed, or can be formed by splicing as in this embodiment. For example, as Figure 2 and Figure 3 shown, after the ceiling heightening board 52 is vertically spliced with the upper ceiling board 51, a number of L-shaped corner codes are provided at the connection between the two. The horizontal plate of the corner code is closely attached to the upper ceiling board 51 and is welded or screwed, and the vertical plate is closely attached to the ceiling heightening board 52 and is welded or screwed. The corner code can be provided at the external or / and internal corners of the vertical structure of the ceiling heightening board 52 and the upper ceiling board 51. In order to avoid affecting the beauty of the backlight trough, it is provided at the external corner as shown in Figure 2 the figure.

[0033] The connection between the wallboard heightening board 53 and the upper ceiling board 51 is the same in principle and can also adopt the above corner code structure. Further, in order to improve the connection strength between the two, asFigure 1 As shown, a relatively thick wall panel and a wall panel extension 53 are adopted. A semi-groove is provided at the upper end of the wall panel extension 53. After the end of the high-position ceiling panel 51 is inserted into the semi-groove, it is fixed by an angle code. This thickened wall panel extension 53 with a semi-groove can be directly formed by splicing two plate members with different heights.

[0034] In the above structure, both ends in the width direction of the high-position ceiling panel 51 are supported and enclosed by the ceiling panel extension 52 and the wall panel extension 53 respectively. Further, as Figure 2 shown, there are also closure plates between both ends in the length direction of the high-position ceiling panel 51 and the wall panels 3 provided on the first side wall respectively, so as to be further supported and enclosed by the closure plates, making the heightened structure form an enclosure structure with better integrity. The structure of the closure plate and its installation method with the wall panel 3 and the ceiling panel extension 52 are the same as those of the wall panel extension 53. In addition, as Figure 3 shown, the closure plates are also connected to the ceiling panel extension 52 and the wall panel extension 53 respectively by angle codes.

[0035] When installing this heightened structure, first assemble the ceiling panel extension 52, the high-position ceiling panel 51, the wall panel extension 53, and the closure plates on the ground, and install high-position keels 6 on the back of the high-position ceiling panel 51, then lift the whole body upward so that the bottom ends of the two closure plates overlap on the top of the wall panel 3 of the first side wall, and then move the whole body to the right, connect the high-position keels 6 to the top wall, and make the bottom end of the wall panel extension 53 overlap on the top of the wall panel 3 of the second side wall; further adjust the position to make the wall panel extension 53 flush with the wall panel 3.

[0036] In order to improve the installation stability, generally, an adhesive can be coated on the bottom end of the wall panel extension 53 or / and the top of the wall panel 3 before lifting, and as in this embodiment, a connecting member can also be added between the two. As Figure 1 and Figure 4As shown, the connecting member first includes a flush plate 71 which is vertically arranged. The front surface of the wall panel 3 and the front surface of the wall panel heightening plate 53 are both in contact with the flush plate 71, so as to ensure the flushness of the wall panel 3 and the wall panel heightening plate 53 through the flush plate 71. The connecting member also includes a fixing plate 72 for fixing the flush plate 71. The fixing plate 72 is vertically connected to the flush plate 71. The fixing plate 72 is inserted between the wall panel heightening plate 53 and the wall panel 3 and is connected to the top surface of the wall panel 3. The connection method is not limited and can be adhesive bonding, screw connection, etc. Further, in order to improve the connection strength and balance the force of the connecting member, the connecting member also includes a limiting plate 73 arranged on the fixing plate 72. One side of the wall panel heightening plate 53 is in contact with the flush plate 71 and the other side is in contact with the limiting plate 73. An adhesive can be added between the wall panel heightening plate 53 and the limiting plate 73, or it can be fixed by screw connection. The connecting member also includes a reinforcing plate 74 arranged on the fixing plate 72. The reinforcing plate 74 is connected to the side of the wall panel 3 close to the second side wall. The connection method is also not limited. It can be achieved by controlling the thickness of the wall panel 3 to be slightly greater than the distance between the flush plate 71 and the reinforcing plate 74, so that the wall panel 3 is inserted between the flush plate 71 and the reinforcing plate 74 and is in interference fit with them, or it can be connected by adhesive bonding. The flush plate 71, the fixing plate 72, the limiting plate 73, and the reinforcing plate 74 are preferably integrally formed.

[0037] After the installation of the heightening structure is completed, install the low ceiling board 1. First, install the low ceiling board 1 and the low keel 2 on the ground, and pay attention to controlling the installation position of the low keel 2. As Figure 1 shown, there is a blank part near the second side wall on the back of the low ceiling board 1. After assembly, directly lift the low ceiling board 1 upwards so that the low keel 2 is connected to the top wall. Then, an integrally formed L-shaped reinforcing member is added between the low ceiling board 1 and the ceiling heightening board 52. The reinforcing member includes a first connecting part parallel to and connected to the low ceiling board 1 and a second connecting part parallel to and connected to the ceiling heightening board 52. Further, in order to improve the connection strength, the length of the high ceiling board 51 and the height of the ceiling heightening board 52 can also be controlled so that after the low ceiling board 1 is installed, the bottom end of the ceiling heightening board 52 just abuts against the folded edge part 21 of the low keel 2, and it is pressed on the low keel 2 to improve the installation strength between the low ceiling board 1 and the low keel 2. Further, a number of reinforcing screws 54 are also added so that the reinforcing screws 54 sequentially pass through the second connecting part of the reinforcing member, the ceiling heightening board 52, and the two vertical parts of the low keel 2 to improve the connection strength.

[0038] After the above installation, a part of the lower ceiling board 1 is located in the backlight trough, which is called the installation part. Install the lamp 13 on the back of this installation part to achieve backlighting. The lamp 13 is preferably installed in a detachable manner such as by gluing, which is convenient for subsequent maintenance and replacement. At the same time, in order to prevent the rough edge of the lower ceiling board 1 from hurting the operator, a protective cover is also provided on it to wrap the edge of the lower ceiling board 1.

[0039] Based on the above structure, the installation method of this wall and ceiling heightening structure includes the following steps:

[0040] S1. Install the connecting piece on the wall panel 3; after splicing the ceiling heightening board 52, the upper ceiling board 51, the wall panel heightening board 53, and the upper keel 6 into a whole on the ground and then lifting it, connect the upper keel 6 to the top wall body, and insert the bottom end of the wall panel heightening board 53 between the flush board 71 and the limiting board 73 of the connecting piece;

[0041] S2. Lift the lower ceiling board 1 so that the lower keel 2 is connected to the top wall body. Then, set a reinforcing piece between the lower ceiling board 1 and the ceiling heightening board 52.

[0042] 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.
