Description

Technical Field

[0001] The present invention relates to the technical field of decoration design, and in particular, the present invention relates to an assembled ceiling edge closing structure and an installation method thereof. Background Art

[0002] At present, the decoration industry is developing towards the direction of industrialized modular installation. Generally speaking, interior decoration is a commonly used decoration method in interior design, which can increase the sense of hierarchy of the interior space and play a role in beautifying the decoration.

[0003] Now, the installation of wall panels and ceiling panels is required in many indoor houses. Currently, most of the wall panel decorations still adopt the traditional wet construction method. In wet construction, the wall panels are usually pasted from top to bottom with cement mortar, so there is no need to consider the top edge closing problem. However, with the rise of assembled installation, in order to facilitate the installation of the ceiling, it is necessary to close the top of the wall panel. For example, Chinese Patent Invention Patent CN113136987A discloses an assembled wall top edge closing system and an installation method thereof, including a triangular keel, an original wall, an extruded plastic wall panel and a top edge closing member. The extruded plastic wall panel is arranged on the original wall, a triangular keel is arranged on the original wall at the position above the top of the extruded plastic wall panel, the top edge closing member is placed on the triangular keel, and the top edge closing member can be connected and matched with the extruded plastic wall panel. The beneficial effects of the above invention are: 1) The leveling plate of the top edge closing member can cooperate with the inclined surface of the triangular keel to level and support the top of the extruded plastic wall panel. 2) A counterweight block is arranged on the top edge closing member, and the counterweight block is pressed on the top of the extruded plastic wall panel by its own weight without additional fixation; 3) The extruded plastic wall panel is arranged in the horizontal gap between the clamping member and the edge closing plate, so that the top edge closing member can be clamped and fixed with the extruded plastic wall panel; Another example is Chinese Patent Invention Patent CN113356437A discloses a ceiling edge closing member and an installation method thereof, including a hanging member, a fixing member, and a leveling member. The hanging member includes a bottom plate, a first hanging plate, a second hanging plate, and a limiting plate. The bottom plate is in close contact with the ceiling panel, the limiting plate is in contact with the end of the ceiling panel, and the first hanging plate and the second hanging plate are provided with hanging parts on the side facing the limiting plate. The first hanging plate and the second hanging plate are both inserted into the keel and fixed, and the hanging parts are located outside the end of the keel; The fixing member includes a fixing plate and a shock absorption structure. The fixing plate is attached to the wall and fixed to the wall through a leveling member. The shock absorption structure is fixed to the lower end of the fixing plate. The shock absorption structure is provided with a third elastic plate corresponding to the hanging part, so that after the hanging member is fixed to the keel, it can be hung on the fixing member to form a connection and bearing structure. It has good shock absorption effect and quick installation; it has a self-limiting structure to form a tight combination relationship; it can quickly level the edge closing member.

[0004] However, the above-mentioned edge trimming structure at the top of the ceiling still has the following problems: the structure is complex. Whether it is the ceiling edge trim or the wall edge trim, they are all assembled from multiple components. When installing at the ceiling position on the top of the wall, a ladder is needed and the line of sight is blocked, making the installation very troublesome. Moreover, there is no transition between the ceiling edge and the top of the wall panel, resulting in poor compatibility between the ceiling panel and the wall panel and poor structural stability.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present invention and its application or use.

[0034] Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and systems should be regarded as part of the authorization specification.

[0035] Example 1: As Figures 1 to 5 shown, it is only one of the embodiments of the present invention. An assembled ceiling edge trimming structure includes a wall edge trimming member 1 provided on the wall panel 4 and a ceiling edge trimming member 3 provided on the ceiling panel 5. The wall edge trimming member 1 includes a first vertical plate 11 provided on the side of the wall panel 4 close to the wall body, a second vertical plate 12 provided on the side of the wall panel 4 away from the wall body, and a connecting cross plate 13 for connecting the first vertical plate 11 and the second vertical plate 12. The cross plate 13 is connected to the top end of the wall panel 4. The ceiling edge trimming member 3 includes a main cross plate 31 and a connecting frame 32 provided on the lower side of the main cross plate 31. The lower side of the connecting frame 32 is connected to the upper side of the ceiling panel 5 through an adhesive, and the main cross plate 31 is connected to the upper side of the connecting cross plate 13.

[0036] In the present invention, the wall panel edge trimming member 1 is used to trim the top end of the wall panel 4. While facilitating the installation of the ceiling, it can also make a structural transition between the wall panel 4 and the ceiling, with better aesthetics; the ceiling panel edge trimming member 3 is used to trim the edge of the ceiling panel 5. While facilitating the installation of the ceiling panel 5, it can also make a transitional connection between the edge of the ceiling panel 5 and the top end of the wall panel 4, with better aesthetics;

[0037] Specifically, the upper end of the wall panel 4 is trimmed and fixed through the wall panel edge trimming member 1, and the ceiling panel 5 is connected through the ceiling panel edge trimming member 3, and then carried on the upper end of the wall panel 4 to complete the mating connection between the ceiling panel 5 and the wall panel 4.

[0038] First, it is the structure of the wall panel edge trimming member 1. The wall panel edge trimming member includes a first vertical plate 11 provided on the side of the wall panel 4 close to the wall body, a second vertical plate 12 provided on the side of the wall panel 4 away from the wall body, and a connecting cross plate 13 for connecting the first vertical plate 11 and the second vertical plate 12. The cross plate 13 is connected to the top end of the wall panel 4, making the entire wall panel edge trimming member form a C-shaped member with an opening downward, covering the top end of the wall panel 4. The first vertical plate 11 is directly attached to the back side of the wall panel 4, the second vertical plate 12 can limit the front side of the wall panel 4, and the lower end of the connecting cross plate 13 also contacts the top end of the wall panel 4.

[0039] Here, a support platform for connecting with the ceiling edge trimming member 3 is provided on the upper side of the cross plate 13. To be precise, the upper side surface of the cross plate 13 forms a support platform, and the ceiling edge trimming member 3 can be directly installed on the upper side surface of the cross plate 13.

[0040] Next is the structure of the ceiling edging member 3. The ceiling edging member 3 includes a main horizontal plate 31 connected to the top end of the wall panel 4 and a connection frame 32 disposed on the lower side of the main horizontal plate 31. The lower side of the connection frame 32 is connected to the upper side of the ceiling panel 5 by adhesive.

[0041] Among them, the connection frame 32 is connected to the upper side of the ceiling panel 5, and the main horizontal plate 31 extends from the connection frame 32 towards the wall surface. When installing the ceiling panel 5, first install the ceiling edging member 3 on the upper side of the ceiling panel 5, then lift the ceiling panel 5 as a whole so that the main horizontal plate 31 is located on the upper side of the wall panel 4, and finally place the main horizontal plate 31 on the top end of the wall panel 4 to complete the installation of the ceiling panel 5.

[0042] Here, the installation of the ceiling panel 5 is not carried out from the side of the ceiling panel 5, but from the upper side of the ceiling panel 5 through the ceiling edging member 3. In this way, the occupied area of the ceiling panel 5 will not increase during installation, the gap between the ceiling panel 5 and the wall panel 4 is smaller, and the connection structure is also very stable by connecting to the upper side of the ceiling panel 5.

[0043] Certainly, the thickness of the connection frame 32 can be selected so that the installation height of the ceiling panel 5 is controllable.

[0044] Finally, a decorative horizontal plate 14 extending away from the wall panel 4 is provided at the bottom end of the second vertical plate 12. A ceiling support member 2 for connecting to the ceiling is provided below the decorative horizontal plate 14. The ceiling support member 2 includes an upper horizontal plate 21 connected to the lower side of the decorative horizontal plate 14, a lower horizontal plate 22 for supporting the ceiling, and a connecting vertical plate 23 for connecting the upper horizontal plate 21 and the lower horizontal plate 22. The ceiling support member 2 can further limit the ceiling panel 5 at the decorative horizontal plate 14.

[0045] The upper horizontal plate 21 is connected to the outer side of the wall panel 4. The lower horizontal plate 22 is used to limit the lower side of the ceiling panel 5, and the connecting vertical plate 23 abuts against the end of the ceiling panel 5 to complete the connection transition between the ceiling panel 5 and the wall panel 4. In addition, it can cover the connection part between the ceiling panel 5 and the wall panel 4, playing a role in beautification.

[0046] Certainly, both the ceiling edging member 3 and the ceiling support member 2 are integrally formed parts, making the edge installation of the ceiling panel 5 more convenient and fast. First, fix the ceiling edging member 3 to the upper side of the ceiling panel 5, then place the ceiling edging member 3 on the top end of the wall panel 4 to complete the installation of the ceiling panel 5, and finally use the ceiling support member 2 for auxiliary support and beautification.

[0047] Embodiment 2, still as Figures 1 to 5As shown, this is only one embodiment of the present invention. On the basis of Embodiment 1, in an assembled ceiling edge trimming structure of the present invention, a decorative panel 41 is provided on the side of the wall panel 4 away from the wall. The decorative panel 41 can be a ceramic tile or a wall panel. An extension plate 15 extending in the direction of the wall panel 4 is provided on the second vertical plate 12, and the extension plate 15 is connected to the top end of the decorative panel 41. Then, the extension plate 15 can limit the upper end of the decorative panel 41, and the second vertical plate 12 limits the outer side of the decorative panel 41.

[0048] Then, the length of the extension plate 15 is not less than the thickness of the decorative panel 41.

[0049] When the length of the extension plate 15 is equal to the thickness of the decorative panel 41, the distance between the first vertical plate 11 and the second vertical plate 12 is exactly equal to the sum of the thicknesses of the wall panel 4 and the decorative panel 41. When the first vertical plate 11 can be in close contact with the back of the wall panel 4, the end of the extension plate 15 away from the second vertical plate 12 just abuts against the front side of the wall panel 4, and the second vertical plate 12 just contacts and abuts against the front side of the decorative panel 41.

[0050] Of course, in order to facilitate the installation of decorative panels 41 of different specifications, a first height surface 151 and a second height surface 152 with a height lower than the first height surface 151 are provided on the lower side of the extension plate 15. The second height surface 152 is provided on the side of the first height surface 151 away from the wall, and the first height surface 151 and the second height surface 152 are connected by a vertical surface 153;

[0051] That is, decorative panels 41 of different specifications can be selected;

[0052] A decorative panel 41 with a thickness equal to the length value of the extension plate 15 can be selected. The top end of the decorative panel 41 contacts the second height surface 152, and the outer side of the decorative panel 41 contacts the second vertical plate 12;

[0053] A decorative panel 41 with the same length value and thickness as the first height surface 151 can also be selected, so that the top end of the decorative panel 41 contacts the first height surface 151, and the outer side of the decorative panel 41 contacts the vertical surface 153.

[0054] Embodiment 3, still as Figures 1 to 5 As shown, this is only one embodiment of the present invention.

The lower cross plate 22 is used to limit and decorate the lower side of the ceiling, and the connecting vertical plate 23 abuts against the end of the ceiling board 5.

[0055] Moreover, the support platform includes a first platform 131 and a second platform 132 with a height lower than that of the first platform 131. The second platform 132 is disposed on the side of the first platform 131 away from the wall, and the first platform 131 and the second platform 132 are connected by an inclined surface 133.

[0056] That is, the main cross plate 31 can be mounted on platforms at different heights to change the installation height of the suspended ceiling. The inclined surface 133 between the two platforms enables the suspended ceiling to slide conveniently from the second platform 132 to the first platform 131.

[0057] Certainly, a contact plate 211 for connecting with the decorative panel 41 is provided at one end of the upper cross plate 21 close to the wall panel 4.

[0058] Moreover, as a preference of the present invention, a connecting screw 121 for connecting with the wall panel 4 and a screw groove 122 for facilitating the installation of the connecting screw 121 are provided on the second vertical plate 12.

[0059] It should be noted that the above screw groove 122 is located on the upper side of the extension plate 15, so that the installation of the connecting screw 121 will not damage the decorative panel 41 located on the lower side of the extension plate 15.

[0060] Finally, the suspended ceiling support 2 is an integrally formed part. Certainly, the wall edge trim is also an integrally formed part.

[0061] Embodiment 4, still as Figures 1 to 4 shown, is only one of the embodiments of the present invention. On the basis of any of the above embodiments, in an assembled suspended ceiling edge trim structure of the present invention, a glue application groove 321 for facilitating the application of the adhesive is provided on the lower side of the connecting frame 32.
