Description

Technical Field

[0001] The present invention relates to the field of interior decoration, and particularly to a trimming structure and an installation method thereof. Background Art

[0002] When installing an assembled ceiling, there is a gap between the single panel (trimming board) closest to the wall and the wall. If the trimming board is directly nailed to the wall, the nail holes are directly exposed, and the decorative wall panel cannot cover the nail holes, affecting the appearance of the hanging nails. Moreover, when installing an assembled ceiling, I-shaped members are often used to hang and fix the ceiling panels under the keel. Since the I-shaped members themselves have a certain thickness, there is a gap between the panel and the keel. The traditional nailing and fixing method cannot control the gap between the keel and the panel, and it is easy for the panel to tilt, affecting the ceiling effect. In addition, after the trimming board is directly fixed to the wall during the installation of the assembled ceiling, the weight of the keel structure is borne by the panel and then supported by the hanging and fixing structure. The strength of the panel is not as good as that of the keel, which will affect the ceiling installation effect.

[0003] In the utility model with the patent number CN201120281545.6 and the name of the combined trimming strip for ceiling, a combined trimming strip structure for ceiling is disclosed, which can be used for installing with the gusset plate (ceiling panel) and for supporting the ceiling structure. This device is also directly installed and fixed with the panel structure in the ceiling system, and some parts of the structure are fixed to the wall by screws, so as to realize the trimming and fixing and supporting functions. In fact, this device does not consider that the strength of the gusset plate is lower than that of the keel structure, resulting in the problem that the gusset plate may not meet the support strength requirements when supporting the keel. Moreover, it does not consider the gap between the gusset plate and the keel and how to control the gap to keep the gusset plate and the keel parallel. Its own structure is not simple enough, and the installation operation is not convenient enough. Summary of the Invention

[0004] The present invention is to overcome the defects that the existing trimming structure of the ceiling has low installation efficiency, large disassembly difficulty, and insufficient aesthetics, and provides a trimming structure and an installation method thereof to overcome the above defects.

[0005] To achieve the above invention purpose, the present invention is realized through the following technical solutions:

[0006] A trimming structure, comprising:

[0007] A hanging member, with 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;

[0008] A trimming line, with a connecting plate provided at its upper end for clamping with the clamping cavity at the lower end of the hanging member. A trimming line is provided downward at the center of the connecting plate, and the trimming line is closely attached to the wall.

[0009] In the edge-closing structure described in the present invention, the edge-closing line is fixedly connected to the hanging member by means of snap connection, and there is no need to use methods such as nailing to connect with the wall and the hanging member during the installation process, thereby effectively reducing the installation difficulty of the edge-closing line. Since the snap connection method will not cause deformation of the edge-closing line, its aesthetics and safety can be guaranteed after installation.

[0010] Preferably, a support member is provided on the side of the edge-closing line away from the wall, and a second snap groove for snapping the decorative panel is formed between the support member and the connecting plate.

[0011] In the present invention, a support member is provided on the side of the edge-closing line away from the wall, so it can be used to support the decorative panel, so that the gap between the decorative panel and the edge-closing line can be effectively covered, effectively improving the aesthetics.

[0012] Preferably, the cross-section of the support member is triangular.

[0013] Setting the cross-section of the support member to be triangular can effectively improve the mechanical stability of the support member after being pressed by the decorative panel.

[0014] Preferably, an accommodation cavity is provided at the upper end of the hanging member, a notch is provided on one side of the accommodation cavity, and a stress support plate is provided above the notch.

[0015] Preferably, it further includes a concave keel, and the concave keel is inserted into the accommodation cavity at the upper end of the hanging member.

[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 fits against the bottom of the accommodation cavity. A straight edge that abuts against the other side of the accommodation cavity is provided on the other side of the concave keel, and there is a gap between the bottom of the straight edge and the bottom of the accommodation cavity.

[0017] In addition, for the keel in the prior art, when it cooperates with the hanging member, usually only the bottom of it contacts the hanging member, 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 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 of the concave keel contacts the bottom of the accommodation cavity at the lowest end. 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.

[0018] Moreover, compared with the closed rectangular structure, this structure effectively reduces the material consumption of the keel, making the keel lighter in weight.

[0019] Preferably, a groove is further provided at the center of the concave keel;

[0020] A first stress area is formed between the groove and the bent edge;

[0021] A second stress area is formed between the groove and the straight edge.

[0022] There are two purposes for providing a groove at the center of the concave keel in the invention. First, 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, so that the first stress area and the second stress area separately bear the pressure received, 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 capacities of the two areas are greatly improved. Second, the design of the groove can facilitate the tightening operation of the expansion screw up and down, provide corresponding expansion space for the expansion screw, and will not damage the concave keel itself during the process of screwing the screw.

[0023] Preferably, the second stress area is a closed rectangular block, the straight edge is provided at the outermost side of the rectangular block, and the bottom of the groove is located at the center of the rectangular block.

[0024] Due to the special structure of the concave keel of the present invention, the straight edge in the second stress area is subject 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.

[0025] At the same time, when the rectangular block is subject to the pressure transmitted from the side of the hanging part, there is a risk of rotational deformation along the connection point between the bottom of the groove and the rectangular block. Therefore, placing the bottom of the groove at the center of the rectangular block can balance the force of the rectangular block, make the upper and lower moments the same, and reduce the risk of deformation.

[0026] Preferably, the lower end of the bent edge extends outward from the notch.

[0027] 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 at the bottom of the bent edge towards the inside of the notch. 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 likely to be bent and deformed. Therefore, by setting the lower end of the bent edge to face the outside of the notch, the structural stability of the bent edge can be effectively improved.

[0028] Preferably, a C-shaped connecting member with an opening on the side is fixedly connected above the wall body. A placing cavity for installing a concave keel is arranged inside the C-shaped connecting member, and the bottom of the placing cavity is fixedly connected with the wall body.

[0029] Therefore, the present invention has the following beneficial effects:

[0030] (1) In the edge closing structure of the present invention, the edge closing line is fixedly connected with the hanging part by a clamping method, and there is no need to use methods such as nailing to connect with the wall body and the hanging part during the installation process, so that the installation difficulty of the edge closing line can be effectively reduced.

[0031] (2) Since the clamping connection method will not cause deformation of the edge closing line, its aesthetics and safety can be guaranteed after installation.

[0032] (3) Through the design of the hanging keel with a single-layer structure in the present invention, the floor height occupied by the keel can be effectively reduced, thereby effectively increasing the height of the room, greatly alleviating the sense of space depression. At the same time, through the unique keel structure design, the overall structure of the keel can be used to bear the weight of the keel itself and the components below, 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.

Detailed implementation manners

[0042] The present invention will be further described below in conjunction with 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 generally 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 scope of protection of the present invention.

[0043] Embodiment

[0044] As Figures 1 - 8 shown, a kind of edge trim structure includes: a concave keel 10, and a hanging member 20 is respectively arranged on each of the left and right sides of the concave keel 10. A edge trim line 50 is arranged below the hanging members 20 at the left and right ends of the concave keel 10, and the edge trim line 50 is closely attached to the wall body 60.

[0045] Wherein: the hanging member 20 is in the shape of a "6", 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 member 20 above the notch 22 forms a stress support plate 23.

[0046] The concave keel 10 is generally in the shape of a concave character, and a horizontal edge is missing at its lower end. A downward groove 13 is arranged at its center. Therefore, a first stress-bearing area 14 is formed on one side of the groove 13, and a second stress-bearing area 15 is formed on the other side of the groove.

[0047] Wherein, a bent edge 11 is arranged on the side of the first stress-bearing area 14 away from the groove 13. The upper end of the bent 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 accommodating cavity 21, so as to play a role in limiting the concave keel 10. The lower end of the bent edge 11 is a horizontal edge, the lower end of which is in contact with the bottom of the accommodating cavity 21, and its end extends to the outside of the notch 22 and to the outside of the hanging member 20.

[0048] The second stress-bearing area 15 is a rectangular closed rectangular block 16. Since the concave keel 10 of the present invention has a special structure, the stress at the second stress-bearing area 15 is relatively large. Therefore, setting the second stress-bearing area 15 as a rectangular block 16 can effectively improve the structural stability of the second stress-bearing area 15, so that the second stress-bearing area 15 will not be deformed when stressed.

[0049] In addition, in order to ensure the structural stability of the second stress-bearing 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 risk of deformation.

[0050] The outermost side of the second stress-bearing 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.

[0051] The concave keel 10 in the present invention adopts a special structural design. First, only the lower end of the bent edge 11 at the lowermost end of the concave keel 10 contacts 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 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 bent edge 11 being in contact with the stress support plate 23, the bottom of the bent edge 11, the top of the bent edge 11, and the straight edge 12 finally form a three-point co-supporting effect, thereby dispersing the stress of the concave keel 10, changing the originally one-sided stress structure into an overall stress structure, increasing the sectional moment of inertia of the concave keel 10, and improving the structural stability of the concave main keel 10.

[0052] In addition, a connection part 24 for connecting other connecting pieces is provided below the accommodation cavity 21 of the hanging piece 20. The connection part 24 includes a clamping cavity 25, and a through groove 26 penetrating the connection part 24 is provided at the bottom of the clamping cavity 25. Therefore, through the setting of the clamping cavity 25 and the through groove 26, the present invention can simplify the connection and installation of the components below the keel, has strong versatility, is convenient for installation, greatly improves the installation efficiency, and makes the assembly simpler. At the same time, the adjustable splicing of the large-space flat ceiling is realized.

[0053] In some preferred embodiments, strip-shaped grooves 27 communicating with the clamping cavity 25 can be provided on the left and right sides of the connection part 24, so as to effectively reduce the self-weight of the hanging piece without affecting the bearing capacity of the hanging piece 20 and improve the structural stability.

[0054] In order to hang the concave keel 10 and the hanger 20 on the roof, the present invention further provides a hanging rod 28 on some hangers 20. In some preferred solutions, the hanging rod 28 can be connected to the top of the hanger 20 by fixing means such as expansion screws. The design of the groove of the hanger 20 can facilitate the 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 screwing process.

[0055] 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.

[0056] 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.

[0057] 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.
