Description

Technical Field

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

[0002] The assembled decoration ceiling is a decoration method that is produced by the factory through the modularization of materials and assembled on-site by dry construction. Compared with the traditional woodworking ceiling decoration, the assembled integrated ceiling has many 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 jointing gypsum.

[0003] Currently, in the assembled ceiling system, the overall installation of the ceiling is completed by nailing, which results in relatively low installation efficiency and increases the difficulty of subsequent disassembly. At the same time, nailing makes the board prone to deformation problems, affecting the aesthetics and safety of the overall ceiling. Moreover, the existing ceilings are all double-layer keels, which increases the amount of materials and the installation difficulty. Summary of the Invention

[0004] The present invention is to overcome the defect of low installation efficiency of the hanging structure in the prior art, and provides a hanging structure for a ceiling 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 hanging structure, comprising:

[0007] A hanging member, having a receiving cavity at its upper end and a connecting portion 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 concave keel, which is arranged inside the receiving cavity;

[0009] An I-shaped member, 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. The clamping edge is clamped and fixed with the clamping cavity of the connecting portion at the lower end of the hanging member. Two clamping grooves are symmetrically arranged in the area between the upper clamping edge and the lower clamping edge along the connecting column;

[0010] A decorative panel, which is clamped in the clamping grooves at the lower ends of adjacent I-shaped members.

[0011] 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 interior and greatly alleviating the space depression.

[0012] Meanwhile, a connecting part is provided below the hanging part. The hanging part is clamped with the upper clamping edge at the upper end of the I-shaped part through the clamping cavity in the connecting part, which can effectively simplify the connection between the I-shaped part and the hanging part. The decorative panel and the I-shaped part also adopt a snap-in connection method. Compared with the traditional screw connection, this method in the present invention can effectively improve the installation efficiency of the suspended ceiling, reduce the difficulty of subsequent disassembly, and avoid the deformation problem of the board caused by nailing. Therefore, the safety can be effectively improved without affecting the aesthetics of the overall suspended ceiling.

[0013] Preferably, a notch is provided on one side of the accommodating cavity, and a stress support plate is provided above the notch.

[0014] Preferably, one side of the cross-section of the concave-shaped 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 accommodating cavity, and the lower end of the bent edge abuts against the bottom of the accommodating cavity. A straight edge that abuts against the other side of the accommodating cavity is provided on the other side of the concave-shaped keel, and there is a gap between the bottom of the straight edge and the bottom of the accommodating cavity.

[0015] In addition, when the keel in the prior art cooperates with the hanging part, usually only the bottom of the keel contacts the hanging part, 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-shaped keel in the present invention adopts a special structural design. First, only the lower end of the bent edge at the lowermost end of the concave-shaped keel contacts the bottom of the accommodating cavity. Therefore, during actual installation, the keel will tilt towards the straight-edge side. Since the straight-edge side abuts against the accommodating 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 stress of the keel, thereby increasing the sectional moment of inertia of the main concave-shaped keel and improving the stability of the keel structure.

[0016] Moreover, compared with the closed rectangular structure, this structure effectively reduces the material consumption of the keel and makes the keel lighter in weight.

[0017] Preferably, a groove is also provided at the center of the concave-shaped keel;

[0018] A first stress area is formed between the groove and the bent edge;

[0019] A second stress area is formed between the groove and the straight edge.

[0020] 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, so as to separate 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, thereby 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. Secondly, the design of the groove facilitates the up and down tightening operation of the expansion screw, provides corresponding expansion space for the expansion screw, and will not damage the concave keel itself during the process of screwing the screw.

[0021] Preferably, the second stress area is a closed rectangular block, 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.

[0022] Due to the special structure of the concave keel in the invention, the straight edge at 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.

[0023] At the same time, when the rectangular block is subjected 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, 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 risk of deformation.

[0024] Preferably, the lower end of the bent edge extends outward from the notch.

[0025] In the invention, since there is a tendency for the concave keel to rotate in the direction opposite to the bent edge, there is 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 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.

[0026] Preferably, a stepped support edge is provided at the end of the upper clamping edge, and the support edge is inserted into the clamping cavity.

[0027] Preferably, an arc-shaped clamping head is provided at the end of the lower clamping edge;

[0028] A number of reinforcing ribs are protruded outward from the middle of the connecting column.

[0029] At the end of the lower clamping edge in the present invention, there is an arc-shaped clamping head. When it is clamped with the decorative panel, only the arc-shaped clamping head contacts the decorative panel. Thus, 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.

[0030] In the middle of the connecting column, there is a reinforcing rib, which can effectively improve the mechanical strength of the connecting column, thereby enhancing the bearing capacity of the I-shaped part.

[0031] Preferably, at the center of the side of the decorative panel, there is an annular groove;

[0032] 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 inside the clamping groove between the upper end surfaces of the decorative panels.

[0033] An installation method of a hanging structure includes the following steps:

[0034] (1) Take several hanging parts, and insert the concave keel into the accommodating cavity of the hanging part, so that the lower end of the bent edge of the concave keel extends towards the outside of the notch;

[0035] (2) Fix the hanging rods at intervals on the top of the hanging parts, and connect the hanging rods to the roof, thereby hanging the concave keel and the hanging parts on the roof;

[0036] (3) Insert the upper clamping edge at the upper end of the I-shaped part into the inside of the clamping cavity;

[0037] (4) Insert the decorative panel into the clamping grooves of adjacent I-shaped parts.

[0038] Therefore, the present invention has the following beneficial effects:

[0039] (1) 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 interior and greatly alleviating the sense of space depression.

[0040] (2) Through the unique keel structure design in 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 of the keel, thereby increasing the section moment of inertia of the concave main keel and improving the stability of the keel structure.

[0041] (3) Simplify the connection and installation of the components below the keel, with strong versatility and convenient installation, greatly improving the installation efficiency, thereby making the assembly simpler. At the same time, adjustable splicing of large-space flat ceilings is achieved. Brief Description of the Drawings

Specific implementation mode

[0051] 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 usually only a part of the embodiments of the present invention, rather than all of 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.

[0052] Embodiment 1

[0053] As Figures 1 - 8 shown, a hanging structure 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 to the lower part of the hanging part 20, and a decorative panel 40 is clamped and connected between the bottoms of adjacent I-shaped parts 30.

[0054] Wherein, the hanging member 20 is in a "6" shape, and an accommodation cavity 21 for accommodating the concave keel 10 is arranged at its upper end. The accommodation cavity 21 is integrally in a rectangular shape, and a notch 22 is arranged at one end of its side. Correspondingly, a stress support plate 23 is formed at the part of the hanging member 20 above the notch 22.

[0055] The concave keel 10 is generally in a concave shape, and a horizontal side 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.

[0056] 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 abutted against the stress support plate 23 of the accommodation cavity 21, so as to be able to limit the concave keel 10. The lower end of the bending edge 11 is a horizontal edge, the lower end of which is attached to the bottom of the accommodation cavity 21, and its end extends to the outside of the hanging member 20 outside the notch 22.

[0057] The second stress area 15 is a rectangular closed block 16. Because of the special structure of the concave keel 10 in 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 be deformed when stressed.

[0058] In addition, in order to ensure the structural stability of the second stress area 15 in the present invention, the bottom of the groove 13 is also connected 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.

[0059] The outermost side of the second stress area 15 is a straight edge 12 when it is in contact with the accommodation cavity 21, and there is a certain gap between the rectangular block 16 and the bottom of the accommodation cavity 21.

[0060] 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 contacts the bottom of the accommodating 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 accommodating cavity 21, the originally unloaded straight edge 21 plays the role of a supporting edge. Coupled with the upper end of the bending edge 11 being in contact with the stress support plate 23, thus finally forming a three-point co-supporting effect of the bottom of the bending edge 11, the top of the bending edge 11, and the straight edge 12, which disperses the force on the concave keel 10, making the originally one-sided force-bearing structure transform into an overall force-bearing structure, thereby increasing the sectional moment of inertia of the concave keel 10 and improving the structural stability of the concave keel 10.

[0061] In addition, a connection part 24 capable of connecting other connectors is provided below the accommodating cavity 21 of the hanging part 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 arrangement of the clamping cavity 25 and the through groove 26 in the present invention, 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.

[0062] 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 part on the premise of not affecting the bearing capacity of the hanging part 20 and improve the structural stability.

[0063] In order to hang the concave keel 10 and the hanging part 20 on the roof, a hanging rod 28 is also provided on some of the hanging parts 20 in the present invention. In some preferred solutions, the hanging rod 28 can be connected above the hanging part 20 by fixing means such as expansion screws. The previous design of the groove of the hanging part 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.

[0064] The I-shaped part 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.

[0065] Among them, a stepped support edge 35 is provided at the end of the upper clamping edge 31. This support edge 35 is inserted into the inside of 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 inside of the clamping cavity 25, and the connecting column 33 passes through the through groove 26, thereby realizing the clamping between the two, and making the I-shaped member 30 hang below the hanging member 20.

[0066] 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. As a result, 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.

[0067] A number 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 improving the bearing capacity of the I-shaped member.

[0068] An annular groove 41 is provided at the center of the side of the decorative panel 40, so that the lower clamping edge 32 at the lower end of the I-shaped member 30 is clamped and adapted to the annular groove 41, and the upper end surface of the annular groove 41 is embedded into the inside of the clamping groove 34 between the upper end surfaces of the decorative panel 40.

[0072] (2) Hang rods 28 are fixedly spaced at the top of the hanging member 20, and the hang rods 28 are connected to the roof, thereby hanging the concave keel 10 and the hanging member 20 on the roof;

[0073] (3) Insert the upper clamping edge at the upper end of the I-shaped member 30 into the inside of the clamping cavity 25;
