Description

Technical Field

[0001] This utility model relates to the field of building technology, and more specifically, to a telescopic flat-surface keel ceiling system. Background Technology

[0002] A suspended ceiling refers to a type of decoration applied to the top of a room. Simply put, it refers to the decoration of the ceiling and is an important part of interior decoration.

[0003] During the installation of a light steel keel ceiling, the edge keel needs to be edge-trimmed and finished around the surface keel. When the surface keel and the edge keel are working together, the longest side of the edge keel needs to wrap around the surface part of the surface keel. This creates a step difference between the longest sides of the surface keel and the edge keel. This height difference is equal to the thickness of the edge keel, which will cause the entire ceiling to be uneven. The gypsum board installation will also be uneven, failing to achieve a flat effect, which seriously affects the construction quality and aesthetics.

[0004] Therefore, how to solve the problem of keel ceilings not achieving a perfectly flat surface is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a telescopic flat keel ceiling system that can make the end face of the gypsum board installed on the edge keel and the keel on the surface of the keel on the same horizontal plane, without any step difference between the two, so that the overall ceiling can achieve a flat effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A telescopic flat-faced keel ceiling system includes: a face keel and an edge keel. The edge keel wraps around the end of the face keel. The end of the face keel is provided with a constriction that cooperates with the edge keel so that the face of the face keel and the end face of the edge keel are on the same horizontal plane. The face keel and the edge keel are connected by a mortise and tenon structure.

[0008] Preferably, the covering keel includes a main covering keel and a secondary covering keel. One end of the secondary covering keel is provided with an inwardly recessed stepped surface, which is movably located within the main covering keel.

[0009] Preferably, the recessed stepped surface is provided with a plurality of first adjustment holes, and the end of the main cover keel connected to the recessed stepped surface is provided with a second adjustment hole corresponding to the first adjustment hole. The first adjustment hole and the second adjustment hole are positioned by a positioning pin.

[0010] Preferably, the diameter of the first adjustment hole and the second adjustment hole is 5mm, and the center distance between two adjacent adjustment holes is 8mm.

[0011] Preferably, the mortise and tenon structure includes mortises provided on the main cover keel and the secondary cover keel, and also includes tenons provided on the side keel that engage with the mortises.

[0012] Preferably, the mortise is a dovetail groove and the tenon is a dovetail plate.

[0013] Preferably, there are at least two keels for the surface and the edge, which are spliced ​​together to form a rectangular closed structure, and the closed structure is provided with a main keel.

[0014] Preferably, there are at least two main keels, and at least two main keels are connected to the overlay keel.

[0015] Preferably, the main keel includes a keel body, which has an inverted U-shaped structure. The two sides of the keel body are provided with wing plates perpendicular to the side plates of the keel body. The wing plates are provided with several ceiling holes, and expansion bolts are provided in the ceiling holes.

[0016] Preferably, the keel body includes a back panel, side panels perpendicular to the back panel, the side panels and the back panel forming an inverted U-shaped structure, the side panels are provided with a number of hooks, and a groove is formed between two adjacent hooks, and the overlay keel is provided with locking bends that cooperate with the hooks.

[0017] This utility model provides a telescopic, flat-faced keel ceiling system, comprising a face keel and an edge keel. Specifically, the face keel and the edge keel are connected by a mortise and tenon structure, eliminating the need for traditional rivets for fixation, making construction faster and more convenient. The edge keel wraps around the end of the face keel, and the end of the face keel has a constriction that mates with the edge keel, ensuring that the face of the face keel and the end face of the edge keel are on the same horizontal plane, achieving a flat surface. This provides a foundation for installing gypsum board, ensuring a perfect fit between the gypsum board and the keel, preventing unevenness. After applying putty, the ceiling achieves a "flat" finish. By setting a constriction at the end of the face keel, there is no step difference between the assembled edge keel and the face keel. In other words, the end faces of the face keel and the edge keel where the gypsum board is installed are on the same horizontal plane, ensuring that the installed gypsum board is on the same horizontal plane, resulting in a flat overall ceiling effect.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] As is well known, in the process of installing a light steel keel ceiling, the edge keel 2 needs to be used to trim and finish the surface keel 1. When the surface keel 1 and the edge keel 2 are working together, the longest side of the edge keel 2 needs to wrap around the surface of the surface keel 1. This creates a step difference between the longest sides of the surface keel 1 and the edge keel 2. The height of this step difference is equal to the thickness of the edge keel 2, which will cause the entire ceiling to be uneven, and the gypsum board installation will also be uneven, seriously affecting the construction quality and aesthetics.

[0037] The core of this utility model is to provide a telescopic flat keel ceiling system that enables the end faces of the gypsum board installed on the edge keel 2 and the keel 1 to be on the same horizontal plane, without any step difference between them, thereby achieving a flat ceiling effect.

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A telescopic flat-surface keel ceiling system includes a surface keel 1 and an edge keel 2.

[0039] Specifically, the facing keel 1 and the edge keel 2 are connected by a mortise and tenon structure 3, eliminating the need for traditional rivets for fixing, making construction faster and more convenient. The edge keel 2 wraps around the end of the facing keel 1, and the end of the facing keel 1 has a contraction 13 that matches the edge keel 2, ensuring that the facing surface of the facing keel 1 and the end face of the edge keel 2 are on the same horizontal plane, achieving a perfectly flat surface. This provides a foundation for installing gypsum board, ensuring a perfect fit between the gypsum board and the keel, preventing unevenness. After applying putty, the ceiling achieves a "perfectly flat" finish. By setting the contraction 13 at the end of the facing keel 1, there is no step difference between the assembled edge keel 2 and the facing keel 1. In other words, the end faces of the gypsum board installed on the assembled facing keel 1 and the edge keel 2 are on the same horizontal plane, ensuring that the installed gypsum board is on the same horizontal plane, achieving a perfectly flat overall ceiling effect.

[0040] The main keel 5 supports the main weight of the gypsum board, while the edge keel 2 serves as an auxiliary support structure. The end of the facing keel 1 has a recess 13 that mates with the edge keel 2. The recess 13 has an inward thickness of 0.5mm (the same as the thickness of the edge keel 2). To ensure a smooth surface, the facing keel 1 and the edge keel 2 are connected by a mortise and tenon joint 3. At this point, the longest side of the edge keel 2 coincides with the bottom recess 13 of the facing keel 1. Thus, the longest bottom edge of the edge keel 2 and the facing surface (50mm long) of the facing keel 1 are on the same horizontal plane, achieving a smooth surface and ensuring a perfect fit between the gypsum board and the keel, preventing unevenness.

[0041] A "flat" ceiling refers to a ceiling surface that is smooth and without complex designs. It is typically used in modern and minimalist interior designs to maintain a sense of simplicity and openness in the space.

[0042] The telescopic flat-faced keel ceiling system designed in the above manner solves the problem of gaps between traditional ceiling paper-faced gypsum board and light steel keel, achieving a seamless fit. The entire ceiling system is completely flat. The edge keel 2 and the face keel 1 are directly connected by mortise and tenon structure 3, which is convenient to operate. The overall structure is stable, and these keel components can be completely disassembled and reused, making it more environmentally friendly, energy-saving, and efficient.

[0043] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The keel 1 includes a main keel 11 and a secondary keel 12. One end of the secondary keel 12 is provided with an inwardly recessed stepped surface 121, which is movably located within the main keel 11.

[0044] It should be noted that different recessed ports are set at both ends of the secondary covering keel 12. The end of the secondary covering keel 12 that mates with the main covering keel 11 is set with a stepped surface 121 with a circumferential recess, and the recessed thickness of the recess 13 is 0.5mm. The end of the secondary covering keel 12 that mates with the side keel 2 is set with a concave recess 13. The longest side of the side keel 2 coincides with the recess 13 of the secondary covering keel 12. In this way, the longest bottom edge of the side keel 2 and the covering surface (50mm long covering surface) of the secondary covering keel 12 are on the same horizontal plane, thus achieving a "perfectly flat" surface.

[0045] By setting the inward stepped surface 121, the main covering keel 11 and the secondary covering keel 12 are moved and connected, so that the covering keel 1 can achieve the effect of expansion and contraction. This makes it suitable for ceilings in various situations. By designing only one ceiling structure, it can be applied to multiple situations, thus improving the applicability of the ceiling structure.

[0046] Existing light steel keel ceiling systems are increasingly trending towards quick-installation and modular construction techniques. Traditional construction involves cutting individual keels to their measured lengths. On-site manual cutting is inaccurate, time-consuming, and labor-intensive. Furthermore, precise dimensional control is crucial during cutting; any dimensional errors can easily lead to material waste. If the workers are not skilled enough, the resulting ceiling may be uneven and misaligned.

[0047] The telescopic flat-faced keel ceiling system proposed in this application is highly practical. It is modularly assembled and does not require cutting the faced keel 1 according to the site length. It only requires direct adjustment of the telescopic faced keel 1 on site and positioning with positioning pins 4. It solves the problem of gaps between the traditional ceiling paper-faced gypsum board and light steel keel, achieving a seamless fit. The entire ceiling system achieves a flat surface, improves on-site construction efficiency, reduces labor costs, and shortens the construction period. Overall, this design can meet the requirements of adjustable length and flat surface process of keel ceiling.

[0048] In the above configuration, the recessed stepped surface 121 is provided with a plurality of first adjustment holes 122, and the end of the main cover keel 11 connected to the recessed stepped surface 121 is provided with a second adjustment hole 111 corresponding to the first adjustment hole 122. The plurality of first adjustment holes 122 are equally spaced, and the plurality of second adjustment holes 111 are equally spaced. The first adjustment holes 122 and second adjustment holes 111 are positioned by positioning pins 4. The diameter of the first adjustment holes 122 and the second adjustment holes 111 is 5 mm, and the center distance between two adjacent first adjustment holes 122 and two adjacent second adjustment holes 111 is 8 mm.

[0049] It is understood that the extendable length range of the covering keel 1 is 0 to 150 mm. The main covering keel 11 and the secondary covering keel 12 are engaged through adjustment holes to adjust their lengths, and finally positioned by the positioning pin 4. In this embodiment, the diameter of the first adjustment hole 122 and the second adjustment hole 111 is 5 mm, and the center distance between two adjacent adjustment holes is 8 mm. However, in practical applications, there are no restrictions on the diameter of the first adjustment hole 122 and the second adjustment hole 111, or the center distance between two adjacent adjustment holes, as long as the above-mentioned technical effect can be achieved.

[0050] Please refer to Figure 3 , Figure 5 and Figure 6 The mortise and tenon structure 3 includes a tenon groove 31 provided on the main cover keel 11 and the secondary cover keel 12, and also includes a tenon 32 provided on the side keel 2 that engages with the tenon groove 31.

[0051] It is understood that in this embodiment, the main cover keel 11 and the secondary cover keel 12 are provided with mortise grooves 31, and the side keel 2 is provided with tenons 32 that engage with the mortise grooves 31. However, in practical applications, mortise grooves 31 can also be provided on the side keel 2, and tenons 32 that engage with the mortise grooves 31 can be provided on the main cover keel 11 and the secondary cover keel 12.

[0052] By setting mortise and tenon joints 31 and 32, the side keel 2 is effectively connected to the main keel 11 and the secondary keel 12. Compared with the method of fixing with rivets, the mortise and tenon structure 3 can be hidden inside the building, making the appearance more beautiful and neat. If the building components of the mortise and tenon structure 3 need to be repaired or replaced, they can be more easily disassembled and reassembled, which is convenient for maintenance, transportation and handling. It can also improve the stability and safety of the structure, and can be adjusted according to different design requirements to adapt to different buildings. No additional accessories are required, reducing material costs. It is reusable, more environmentally friendly and energy-saving, and in line with the modern pursuit of sustainable development.

[0053] Based on the above embodiment, the tenon 31 is a dovetail groove and the tenon 32 is a dovetail plate.

[0054] It should be noted that the dovetail plates of edge keel 2 also form dovetail grooves. During the ceiling installation process, the dovetail plates of edge keel 2 cooperate with the dovetail grooves of the main covering keel 11 and the secondary covering keel 12, respectively, eliminating the need for traditional rivets for fixing. This makes construction more convenient and represents a quick-installation method. The cooperation between the dovetail grooves and dovetail plates enhances the stability of the ceiling, overcomes the drawbacks of traditional connection methods, and allows for quick plug-in and snap-fit ​​connections without the need for auxiliary accessories. By simplifying the connection process, construction time can be shortened and construction efficiency improved.

[0055] Dovetail joint is a mechanical connection method with advantages such as simple structure, convenient installation, and high durability. Dovetail joint can provide high connection strength and stability, and is suitable for occasions requiring high connection strength and rigidity. Dovetail joint has good wear resistance, which can reduce wear and extend service life. The processing and installation of dovetail joint is relatively simple, which can save installation time and costs.

[0056] Please refer to Figure 1 and Figure 2 The keel 1 and the side keel 2 are provided with at least two pieces, which are spliced ​​together to form a rectangular closed structure, and the closed structure is provided with a main keel 5.

[0057] Understandably, in practice, at least two facing keels 1 and two edge keels 2 are typically required, connected end-to-end to form a rectangular frame. The two facing keels 1 are set parallel to each other, and the two edge keels 2 are also set parallel to each other, so that the edge keels 2 can fit snugly against the constricted ends 13 of the two facing keels 1 and engage with the dovetail grooves of the facing keels 1, achieving effective connection and fixation. The entire structure after connection is fixed to the roof by the main keel 5.

[0058] In a preferred embodiment, at least two main keels 5 are provided, and at least two main keels 5 are connected to the overlay keel 1.

[0059] It should be noted that in this embodiment, two main keels 5 are provided to achieve effective connection between the roof and the cladding keel 1 and the edge keel 2. However, in actual applications, the number of main keels 5 is not limited, as long as the above-mentioned technical effects can be achieved.

[0060] In construction, the main keel 5 is the main load-bearing component of the ceiling structure, used to support and fix the entire ceiling structure, ensuring the stability and safety of the ceiling.

[0061] Please refer to Figure 7 and Figure 8 The main keel 5 includes a keel body 51, which has an inverted U-shaped structure. On both sides of the keel body 51, there are wing plates 52 perpendicular to the side plates of the keel body 51. Several ceiling holes 521 are provided on the wing plates 52, and expansion bolts 6 are provided in the ceiling holes 521.

[0062] It is understandable that the main keel 5 is designed with double-wing plates 52 to bear the weight of the paper-faced gypsum board and the covering keel 1 during the ceiling installation process. The double-wing plates 52 are equipped with ceiling holes 521 to facilitate the installation and fixing of expansion bolts 6 and to increase the load-bearing capacity. In the actual ceiling construction process, the number and direction of the main keel 5 should be scientifically and rationally arranged according to the size of the construction site.

[0063] During ceiling construction, the main keel 5 needs to be fixed to the floor slab with expansion bolts 6. The main keel 5 is connected to the floor slab with expansion bolts 6 to ensure the stability and safety of the ceiling. The principle of expansion bolts 6 is to drive expansion bolts 6 into holes in the ground or wall, and then tighten the nuts on the expansion bolts 6 so that the large end of the expansion bolt 6 opens up and is fixed in the hole, thereby achieving the purpose of fixing.

[0064] In the above embodiment, the keel body 51 includes a back panel, and side panels are perpendicular to the back panel, forming an inverted U-shaped structure with the back panel. The side panels are provided with a plurality of hooks 511, and a groove 512 is formed between two adjacent hooks 511. The covering keel 1 is provided with locking bends 14 that cooperate with the hooks 511. The locking bends 14 are located on the side panels of the covering keel 1 and bend towards the inner side of the side panels of the covering keel 1. The locking bends 14 are arc-shaped and cooperate with the curvature of the hooks 511.

[0065] It should be noted that during construction, the hook 511 is engaged within the locking bend 14 to achieve the interlocking connection between the main keel 5 and the overlay keel 1. The keel body 51 is designed with an inverted U-shape to achieve a double-row hook 511 design, making the interlocking more stable.

[0066] The hook 511 is available in two specifications, with the two specifications of hook 511 being arranged alternately.

[0067] The main keel 11, secondary keel 12, main keel 5, and edge keel 2 are all cold-pressed using 0.5mm thick steel strip with pitted surface. For light steel keel ceiling components with holes, the strip steel needs to be punched with a punch press before being cold-pressed.

[0068] In summary, the telescopic flat keel ceiling system provided by this utility model can adjust the length of the keel 1 and the overall flatness. The edge keel 2 and the keel 1 are directly connected by dovetail tenon and mortise joints. It also adopts a double-wing plate 52 to snap the keel 1 structure, which will not cause structural deformation or warping. The snap-fit ​​is more stable and convenient to operate, and the paper-faced gypsum board and the keel are completely bonded together without gaps.

[0069] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0071] The above provides a detailed description of a telescopic, flat-surface keel ceiling system provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
