Abstract
Description
Technical Field
[0001] The present invention relates to the field of interior decoration, and particularly to a hanging keel and an installation method thereof. Background Art
[0002] The assembled decoration ceiling is a decoration method through the component production of materials in the factory and the on-site assembly of dry construction method. 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 common strategy for keel selection is to adopt a double-layer keel, which can effectively improve the load-bearing capacity of the keel. However, since the double-layer keel occupies more floor height, it will result in a lower height of the finally assembled ceiling, making the room more depressing. Currently, there is no good solution to this technical problem. In addition, this double-layer keel in the prior art also has problems such as more material consumption, greater self-weight, and difficult installation.
[0004] Therefore, how to reduce the floor height occupied by the keel while improving the load-bearing capacity of the keel is a key problem urgently needed to be solved in the assembled decoration ceiling. Summary of the Invention
[0005] The present invention aims to overcome the defects that the double-layer keel of the assembled ceiling in the prior art occupies a relatively high floor height and the single-layer keel has a poor load-bearing capacity, and provides a hanging keel and an installation method thereof to overcome the above defects.
[0006] To achieve the above invention purpose, the present invention is realized through the following technical solutions:
[0007] A hanging keel, comprising:
[0008] A hanging piece, with a receiving cavity provided at its upper end, a notch provided on one side of the receiving cavity, and a stress support plate provided above the notch;
[0009] A concave keel, which is arranged inside the receiving cavity. One side of its cross-section 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 receiving cavity, and the lower end of the bent edge fits against the bottom of the receiving cavity. On the other side of the concave keel, there is a straight edge that abuts against the other side of the receiving cavity, and there is a gap between the bottom of the straight edge and the bottom of the receiving cavity.
[0010] The suspended keel in the present invention first adopts the design of a single-layer keel, which first overcomes the defect that the traditional double-layer keel occupies a relatively large floor height, thereby limiting the floor height occupied by the entire keel within 40 mm, effectively increasing the indoor height and greatly reducing the sense of space depression.
[0011] In addition, for the keel in the prior art, when it cooperates with the hanging piece, usually only the bottom contacts the hanging piece, 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 relatively large amount of materials. The concave keel in the present invention adopts a special structural design. First, only the lower end of the bending edge at the lowermost end of the concave keel contacts the bottom of the accommodating cavity. Therefore, during the actual installation process, 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 supporting edge. Coupled with the upper end of the bending 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 concave main keel and improving the structural stability of the keel. And, compared with the closed rectangular structure, this structure effectively reduces the amount of keel materials used, making the keel lighter in weight.
[0012] Preferably, a groove is further provided at the center of the concave keel;
[0013] A first stress-bearing area is formed between the groove and the bending edge;
[0014] A second stress-bearing area is formed between the groove and the straight edge.
[0015] A groove is further provided at the center of the concave keel in the present invention, and there are two purposes. First, through the design of the groove, the concave keel can be divided into a first stress-bearing area and a second stress-bearing area, so as to separate the forces received on the left and right sides of the concave keel, enabling the first stress-bearing area and the second stress-bearing area to separately bear the received pressure, thereby improving the structural stability. At the same time, since the side of the groove provides buffering and strengthening for the bending edge and the straight edge, the separate load-bearing capacity of the two areas is greatly improved. Second, the design of the groove can facilitate the up and down tightening operation of the expansion screw, provide corresponding expansion space for the expansion screw, and the concave keel itself will not be damaged during the process of screwing the screw.
[0016] Preferably, the second stress-bearing area is a closed rectangular block, and the straight edge is arranged on the outermost side of the rectangular block.
[0017] Due to the special structure of the concave keel in the present invention, the straight edge in the second stress-bearing area is subjected to a relatively large stress. Therefore, setting the second stress-bearing area as a rectangular block can effectively improve the structural stability of the second stress-bearing area, so that no deformation problem will occur when the second stress-bearing area is stressed.
[0018] Preferably, the bottom of the groove is located at the center of the rectangular block.
[0019] When the rectangular block is subjected to the pressure transmitted from the side of the hanging member, 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 stress of the rectangular block, make the upper and lower moments the same, and reduce the risk of deformation.
[0020] Preferably, the lower end of the bent edge extends to the outside of the notch.
[0021] 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 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 likely to bend and deform. Therefore, by arranging 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.
[0022] Preferably, a connecting portion is further provided below the hanging member in the receiving cavity.
[0023] In the present invention, a connecting portion is provided below the hanging member, which can be used to connect other connecting members, thus facilitating the connection of the suspended ceiling board.
[0024] Preferably, the connecting portion includes a clamping cavity, and a through groove penetrating the connecting portion is provided at the bottom of the clamping cavity.
[0025] Through the arrangement of the clamping cavity and the through groove in the present invention, the connection and installation of the structure 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 suspended ceiling is realized.
[0026] Preferably, strip-shaped grooves communicating with the clamping cavity are provided on the left and right sides of the connecting portion.
[0027] The provision of the strip-shaped grooves can effectively reduce the self-weight of the hanging member without affecting the bearing capacity of the hanging member, and improve the structural stability.
[0028] Preferably, it further includes hanging rods, which are arranged at intervals on the hanging members for fixing the concave keel;
[0029] Thereby suspending the concave keel and the hanging members on the roof.
[0030] An installation method for a hanging keel includes the following steps:
[0031] (1) Take a plurality of hanging members, and insert the concave keel into the receiving cavity of the hanging member, so that the lower end of the bent edge of the concave keel extends to the outside of the notch;
[0032] (2) Fix the hanging rods at intervals at the top of the hanging member;
[0033] (3) Connect the hanging rods to the roof, so as to hang the concave keel and the hanging member on the roof.
[0034] Therefore, the present invention has the following beneficial effects:
[0035] (1) Through the design of the hanging keel with a single-layer structure, the present invention can effectively reduce the floor height occupied by the keel, thereby effectively increasing the height of the interior and greatly alleviating the sense of space depression.
[0036] (2) Through the unique keel structure design, the present invention can use the overall structure of the keel to bear the weight of the keel itself and the components below, disperse the stress of the keel, thereby increasing the sectional moment of inertia of the concave main keel and improving the stability of the keel structure.
[0037] (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 the large-space flat ceiling is realized. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION
[0045] 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 some embodiments of the present invention, rather than all embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
[0046] Embodiment
[0047] As Figures 1 - 6 shown, a hanging keel includes a concave keel 10 and a plurality of hanging members 20 that cooperate with the concave keel 10.
[0048] Among them: the hanging member 20 is in a "6" shape, and a receiving cavity 21 for receiving the concave keel 10 is provided at its upper end. The receiving cavity 21 is generally in a rectangular shape, and a notch 22 is provided 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.
[0049] The concave keel 10 is generally in a concave shape, and a horizontal edge is missing at its lower end. A downward groove 13 is provided 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.
[0050] Among them, a bending edge 11 is provided 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 abuts against the stress support plate 23 of the receiving 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, its lower end fits against the bottom of the receiving cavity 21, and its end extends to the outside of the notch 22 and to the outside of the hanging member 20.
[0051] The second stress area 15 is a rectangular closed rectangular block 16. Because of the special structure of the concave keel 10 of the present invention, the stress at the second stress area 15 is relatively large. Therefore, setting the second stress area 15 as a rectangular block 16 can effectively improve the structural stability of the second stress area 15, so that the second stress area 15 will not deform when stressed.
[0052] In addition, in order to ensure the structural stability of the second stress 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.
[0053] The outermost side of the second force-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.
[0054] In the present invention, the concave keel 10 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 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-force-bearing 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, finally, the bottom of the bending edge 11, the top of the bending edge 11, and the straight edge 12 together play a supporting role, thereby dispersing the force on the concave keel 10, changing the originally one-sided force-bearing structure into an overall force-bearing structure, increasing the sectional moment of inertia of the concave keel 10, and improving the stability of the structure of the concave main keel 10.
[0055] In addition, a connection part 24 capable of connecting other connecting pieces is provided below the accommodation 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.
[0056] 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.
[0057] 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 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.

[0061] 2 Fix the hanging rod 28 at intervals on the top of the hanging member 20;
