Description

Technical Field

[0001] The utility model relates to the field of suspended ceilings, in particular to a suspended ceiling keel structure. Background Art

[0002] At present, most ceiling keels adopt a profile strip structure, and a supporting convex edge is integrally formed on the side wall of the profile strip. When installing the ceiling, the end of the ceiling is overlapped on the supporting convex edge to support the ceiling through the supporting convex edge. Such a ceiling keel can only support and horizontally limit the ceiling. When the ceiling is subjected to an upward force (for example, an object hitting or the force generated by wind), it is easy to cause a large vibration of the ceiling, which is easy to generate a large noise, and even the ceiling falls off. The safety of its installation and use is low. Although there are now ceiling keels that limit the up and down movement of the ceiling (for example, Chinese patent application numbers CN201611175384.6, CN201920646814.0, CN202223391491.6 and other patent documents), such ceiling keels now have problems such as complex structure, high manufacturing difficulty, high manufacturing cost, and low installation efficiency. Therefore, it is very necessary to redesign the structure of the ceiling keel. Utility Model Content

[0003] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings and to provide a ceiling keel structure, which can be beneficial to the very stable and reliable positioning of the ceiling, which can not only reduce the vibration and noise caused by external forces, but also greatly reduce the probability of the ceiling falling off, and the safety of its installation and use is very high; and its overall structure is relatively simple, which can not only reduce the manufacturing difficulty and manufacturing cost, but also help to improve the installation efficiency of the ceiling.

The structure is characterized in that at least one through hole is opened on the main keel, and at least one bending pressure piece that can be bent to the top of the main convex edge is arranged in the through hole. When the bending pressure piece is bent to the top of the main convex edge, a clamping gap for clamping the ceiling can be formed between the bending pressure piece and the main convex edge.

[0006] Preferably, there are at least two through holes, and the through holes are arranged side by side along the length direction of the main keel.

[0007] Preferably, main convex edges for supporting the ceiling are respectively arranged on the side walls on both sides of the main keel, and the bending pressure sheet can be bent to any side of the main keel and form a clamping gap for clamping the ceiling with the corresponding main convex edge.

[0022] like Figure 1 As shown, a ceiling keel structure described in the utility model includes a main keel 1, and a main flange 11 for supporting the ceiling is arranged on the side wall of the main keel 1. In order to achieve the inventive purpose of the utility model, at least one through hole 12 is opened on the main keel 1, and at least one bending pressure piece 13 that can be bent to the top of the main flange 11 is arranged in the through hole 12. When the bending pressure piece 13 is bent to the top of the main flange 11, a clamping gap 10 for clamping the ceiling can be formed between the bending pressure piece 13 and the main flange 11.

[0023] In the ceiling keel structure, at least one through hole 12 is opened on the main keel 1, and at least one bending pressing piece 13 that can be bent to the top of the main convex edge 11 is arranged in the through hole 12. When the bending pressing piece 13 is bent to the top of the main convex edge 11, a clamping gap 10 for clamping the ceiling can be formed between the bending pressing piece 13 and the main convex edge 11. This can limit the up and down movement of the ceiling by the main convex edge 11 and the bending pressing piece 13, so as to play a very stable and reliable positioning role for the ceiling, which can not only reduce the vibration and noise caused by external forces, but also greatly reduce the probability of the ceiling falling off, and the safety of its installation and use is very high; and its overall structure is relatively simple, which can not only reduce the manufacturing difficulty and manufacturing cost, but also help to improve the installation efficiency of the ceiling.

[0024] A through hole 12 is provided, and a bending press sheet 13 is arranged in the through hole 12, so that both sides of the main keel 1 can act on the bending press sheet 13, so that after one side is overlapped with the ceiling, the bending press sheet 13 can be bent from the other side and pressed on the ceiling. Figure 6 As shown, before the ceiling 100 is overlapped, the bending pressing piece 13 is in the through hole 12. After the end of the ceiling 100 is overlapped on the main flange 11, the bending pressing piece 13 is pressed from the other side of the main keel 1 to bend toward it and press the top surface of the ceiling 100. In this way, the ceiling 100 can be installed and positioned on the main keel 1 quickly and stably, which can help improve the installation efficiency of the ceiling.

[0025] When actually overlapping the ceiling, the last overlapping piece is located at the corner of the wall. In this way, even if the bending pressing sheet 13 cannot be bent and pressed against the last ceiling, it can still ensure that the last ceiling can be installed very stably.

[0026] The above is only one method of installing and positioning the ceiling of the utility model. In the actual installation process, the bending pressing sheet 13 can be bent at a small angle to form the through hole 12, and then the end of the ceiling can be pressed downward from the upper side of the bending pressing sheet 13 into the clamping gap 10, so that the ceiling can be stably fixed. At the same time, other installation methods can also be adopted based on the above structure.

[0027] like Figures 1 to 3 As shown, there are at least two through holes 12, and each through hole 12 is arranged side by side along the length direction of the main keel 1. This can help to play a more stable and reliable positioning role for the ceiling, thereby helping to further improve the reliability of the ceiling keel structure.

[0028] like Figure 1 and Figure 2 As shown, main convex edges 11 for supporting the ceiling are respectively provided on the side walls of the main keel 1, and the bending pressing piece 13 can be bent to any side of the main keel 1, and a clamping gap 10 for clamping the ceiling is formed between the corresponding main convex edge 11. In this way, the requirements of overlapping the ceiling can be met on both sides of the main keel 1, and the ceiling can be stably limited, which can better meet the needs of actual use, thereby helping to further improve the reliability and applicability of the ceiling keel structure.

[0029] like Figure 1 As shown, the main keel 1 comprises a horizontal slat 14 and a vertical slat 15 in the same direction as the length direction of the horizontal slat 14. The lower end of the vertical slat 15 is arranged on the middle of the top surface of the horizontal slat 14. The two sides of the horizontal slat 14 respectively form a main convex edge 11. The through hole 12 is opened through the vertical slat 15. Such a main keel 1 is very simple and reliable, which is not only convenient for manufacturing, but also conducive to stably supporting the ceiling.

[0030] like Figure 1 As shown, a reinforcing strip 16 having a width greater than its thickness is provided on the top edge of the vertical slat 15. This can enhance the structural strength of the main keel 1, thereby helping to further improve the reliability and applicability of the ceiling keel structure.

[0031] like Figure 1As shown, the through hole 12 and the bent pressing piece 13 are both structures stamped and formed on the main keel 1. This not only helps to improve the manufacturing efficiency of the main keel 1, but also ensures that the bent pressing piece 13 has a high structural strength, thereby helping to further improve the clamping and positioning strength of the bent pressing piece 13 on the ceiling, and further helps to further improve the reliability of the ceiling keel structure.

[0032] like Figures 1 to 3 As shown, the horizontal slats 14, the vertical slats 15 and the reinforcing strips 16 are an integrally formed profile structure, that is, the main keel 1 is a profile. The main keel 1 adopts a light steel profile. After the profile is formed, the through hole 12 and the bent pressing sheet 13 are formed by stamping, and then the main keel 1 is obtained by cutting (or cutting first and then stamping). This can meet the actual manufacturing needs and ensure that the main keel 1 has a very high structural strength and durability.

[0033] like Figure 1 As shown, in the actual stamping process, by stamping out a U-shaped hole on the vertical strip 15, the through hole 12 and the bent pressing sheet 13 can be obtained at the same time, which can improve the production efficiency.

[0034] like Figure 2 As shown, the bending pressing sheet 13 is a horizontally extending strip-shaped pressing sheet, one end of the bending pressing sheet 13 is connected to the hole wall of the through hole 12, and an arc-shaped guiding inclined surface 131 is provided on the upper corner of the other end of the bending pressing sheet 13. Such a bending pressing sheet 13 is not only convenient for bending, but also conducive to a more stable and reliable pressing effect, thereby helping to further improve the reliability of the ceiling keel structure. Providing the arc-shaped guiding inclined surface 131 can not only reduce the use of raw materials, but also use the arc-shaped guiding inclined surface 131 to guide when pressing down the ceiling to embed it into the clamping gap 10, which can help improve the convenience and efficiency of ceiling installation and positioning.

[0035] like Figures 1 to 3 As shown, the ceiling keel structure further includes a secondary keel 2, the end of which is inserted and hung on the main keel 1. The secondary keel 2 can limit and strengthen the main keel 1, thereby making the ceiling keel structure more stable and reliable.

[0036] like Figure 3 As shown, a secondary flange 21 for supporting the ceiling is provided on at least one side wall of the secondary keel 2. The secondary flange 21 can enhance the supporting effect on the ceiling, thereby facilitating further improving the stability and reliability of the ceiling installation and positioning.

[0037] like Figure 3As shown, the secondary flange 21 and the secondary keel 2 are an integrally formed light steel profile structure, which can have high structural strength and durability, thereby helping to improve service life and safety.

[0038] like Figure 4 and Figure 5 As shown, the ends of the main keels 1 are respectively provided with plug holes 101 and plug connectors 102 matching the plug holes 101. When two main keels 1 need to be butt-jointed together, the plug connectors 102 on the ends of the two main keels 1 can be respectively plugged into the plug holes 101 on the ends of the other party, so that the butt joints of the two main keels 1 can have a staggered splicing structure, so that the butt joints of the main keels 1 can be very stable and reliable, which helps to further improve the applicability of the ceiling keel structure.

[0039] like Figure 4 and Figure 5 As shown, at least one through hole 103 is formed on the plug connector 102, and the through hole 103 can be made into a waist-shaped hole, and the through hole 103 can be inserted with a rivet or a bolt. When two main keels 1 are butted, the through holes 103 on the two main keels 1 are butted and connected. In this way, the stability and reliability of the butt joint of the two main keels 1 can be enhanced by using rivets or bolts.

[0040] In the actual manufacturing process, a buckle piece that can be buckled onto the hole of the plug hole 101 can also be provided on the plug connector 102, which can also enhance the reliability and stability of the docking.

[0041] like Figure 2 and Figure 3 As shown, the main keel 1 is provided with a plug-in hole 17, and the end of the secondary keel 2 is provided with a plug-in hook 22, and the plug-in hook 22 is plugged into the plug-in hole 17, and hanging holes 18 are respectively provided on the main keel 1 on both sides of the plug-in hole 17. The main keel 1 on both sides of the plug-in hole 17 is provided with hanging holes 18, which is not only conducive to the stable hanging of the main keel 1, but also plays a stable hanging role for the secondary keel 2, so as to ensure that the installation and positioning of the main keel 1 and the secondary keel 2 have high stability and reliability.

[0042] The hanging holes 18 are used for hanging conventional keel hanging tools, so that the ceiling keel structure can be installed and positioned at a required location, thereby meeting the actual installation and use requirements.

[0043] like Figure 3As shown, on the main keel 1, two through holes 12, a hanging hole 18, a plug-in hole 17, a hanging hole 18, and two through holes 12 are arranged side by side in sequence along the length direction of the main keel 1 to form a hole group 20. The two hanging holes 18 are arranged symmetrically about the center of the plug-in hole 17, and the two through holes 12 at the head end and the two through holes 12 at the tail end are arranged symmetrically about the center of the plug-in hole 17; this can make the force more uniform and stable, thereby helping to further improve the reliability and applicability of the ceiling keel structure. There are several hole groups 20 arranged side by side along the length direction of the main keel 1, which can well meet the needs of actual use.

[0044] like Figure 6 As shown, during actual installation, several main keels 1 are arranged side by side horizontally, and each main keel 1 is parallel to each other; several secondary keels 2 are arranged side by side along the length direction of the main keel 1 between adjacent main keels 1, and each secondary keel 2 is parallel to each other, and both ends of the secondary keel 2 are respectively inserted and hung on the main keels 1 on both sides; an installation cavity 200 is formed between each two adjacent secondary keels 2. A ceiling 100 is arranged in the installation cavity 200, and each end of the ceiling 100 is correspondingly overlapped on the main convex edge 11 and the secondary convex edge 21; the bending pressing sheet 13 is bent and pressed tightly on the top surface of the ceiling 100 (the method of pressing the ceiling 100 by each bending pressing sheet 13 can be adopted Figure 6 In the above-mentioned method, two bent pressing sheets 13 are respectively used on the four corners of the ceiling 100; of course, the actual pressing method is not limited to this, and the user can choose according to actual needs). In this way, the demand for stably and reliably limiting the ceiling 100 can be met, which can not only reduce the vibration and noise caused by external forces, but also greatly reduce the probability of the ceiling falling off, and the safety of its installation and use is very high; and its overall structure is relatively simple, which can not only reduce the manufacturing difficulty and manufacturing cost, but also help to improve the installation efficiency of the ceiling.

[0045] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
