Description

Technical Field

[0001] This utility model relates to the field of ceiling keel technology, specifically to a connection structure for architectural decorative ceiling keels. Background Technology

[0002] In modern architectural decoration, ceiling designs require the use of suspended ceiling joists as a framework. A search revealed an existing technology (publication number: CN202222954197.5) for an energy-saving suspended ceiling joist connection structure. The text describes a structure where "the hangers installed with expansion bolts can be removed during dismantling; threaded sleeves are installed on the hangers via bolts, allowing for flexible length changes as needed; clips are installed on the suspended joists via positioning bolts, eliminating the need for drilling during fixing, facilitating future reuse, and being relatively environmentally friendly; the adjusting screw can be used to adjust the length of the threaded sleeve according to the needs of the suspended joists." However, the existing technology suffers from the problem that the length of the adjusting screw and threaded sleeve connection between the joists and hangers is easily affected by external impacts, leading to tilting of the connected suspended ceiling joists and impacting the ceiling's appearance. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a new architectural decorative ceiling keel connection structure is provided to solve the problem that the length of the adjusting screw and threaded sleeve connection between the keel and the hanger is easily changed by external impact, resulting in the ceiling keel tilting and affecting the ceiling effect.

[0004] To achieve the above objectives, a ceiling joist connection structure is provided, comprising: a main ceiling joist and secondary ceiling joists, wherein secondary ceiling joists are attached to and distributed on the lower end face of the main ceiling joist.

[0005] The main ceiling joist has a positioning slider and a limiting slider that are movably engaged on the inner side of its upper end. The positioning slider is connected to the limiting slider through a fixing stud. A fastening nut is screwed onto the surface of the fixing stud. An L-shaped hanger is welded to the lower end of the positioning slider and an L-shaped hanger is welded to the lower end of the limiting slider. Hangers are installed on the surface of the main ceiling joist. An adjusting screw is connected to the upper end of the hanger through a connecting block. A hanging rod is screwed onto the outer surface of the adjusting screw. An anti-detachment plate is connected to the inner side of the lower end of the hanging rod through a positioning stud. An anti-detachment plate is inserted into the surface of the adjusting screw through a limiting groove.

[0006] Furthermore, limiting protrusions are provided on the upper edge of the inner wall of both the main ceiling joist and the secondary ceiling joist, with the main ceiling joist vertically distributed at the upper end of the secondary ceiling joist.

[0007] Furthermore, the positioning slider and the limiting slider are engaged in an "I" shape at the limiting protrusions of the main ceiling keel and the secondary ceiling keel.

[0008] Furthermore, a fixing stud is welded to the side of the positioning slider, and the fixing stud is fixed to the limiting slider by a fastening nut.

[0009] Furthermore, L-shaped hangers one and L-shaped hangers two are symmetrically connected to the outer end face of the secondary ceiling joists; and the sides of L-shaped hangers one and L-shaped hangers two are attached to the main ceiling joists.

[0010] Furthermore, a fixing block is welded to the upper end of the boom, and a limiting groove is symmetrically opened on the threaded rod surface of the adjusting screw; and the limiting groove is rectangular.

[0011] Furthermore, the positioning studs are symmetrically screwed onto the left and right sides of the boom via washers, and the boom is threaded with an adjusting screw on its inner side.

[0012] The beneficial effects of this utility model are as follows: the ceiling keel connection structure of this utility model utilizes an anti-detachment insert plate screwed to the lower end of the hanger rod. The anti-detachment insert plate is inserted into the adjusting screw groove screwed to the hanger rod, which helps to limit the loosening and displacement of the ceiling keel hoisting structure caused by external impact. This facilitates the ceiling keel connection structure to maintain the leveled hoisting height, ensures the stability of the ceiling keel connection structure, and improves the hoisting effect of the ceiling keel connection structure. By adjusting and fixing the screw spacing of the slider and the limiting slider, the L-shaped hanger one and L-shaped hanger two welded to the lower end of the positioning slider and the limiting slider serve as the supporting ceiling keel, effectively preventing the connecting components of the ceiling keel from loosening and detaching from the keel surface, and reducing the safety hazards caused by the detachment of the ceiling keel connection structure.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a connecting structure for architectural decorative ceiling joists, including: a main ceiling joist 1 and a secondary ceiling joist 2, with the secondary ceiling joists 2 attached to the lower end face of the main ceiling joist 1.

[0019] The main ceiling keel 1 has a positioning slider 3 and a limiting slider 32 that are movably connected to the inner side of the upper end. The positioning slider 3 is connected to the limiting slider 32 through a fixing stud 31. The fixing stud 31 is screwed with a fastening nut 33. The lower end of the positioning slider 3 is welded with an L-shaped hanger 6. The lower end of the limiting slider 32 is welded with an L-shaped hanger 61. The main ceiling keel 1 has a hanger 41 installed on its surface. The upper end of the hanger 41 is connected to an adjusting screw 4 through a connecting block 42. The outer side of the adjusting screw 4 is screwed with a hanger 5. The lower inner side of the hanger 5 is connected to an anti-detachment plate 53 through a positioning stud 52. The adjusting screw 4 is inserted with an anti-detachment plate 53 through a limiting groove 43.

[0020] First, fix the hanger rod 5 to the building's roof wall. Then, after determining the hoisting height by measurement, screw the adjusting screw 4 into the hanger rod 5, ensuring that the lengths of the adjusting screw 4 and the hanger rod 5 match the measured hoisting height range. Fine-tune the adjusting screw 4 so that its limiting groove 43 is positioned at the side end of the anti-detachment plate 53. Rotate the positioning stud 52 to insert the anti-detachment plate 53 into the limiting groove 43 of the adjusting screw 4. This locks the adjusting screw 4 and the hanger rod 5 in place, preventing external impacts from causing rotation or movement of the connected adjusting screw 4 and hanger rod 5. Multiple sets of positioning sliders 3 and limiting sliders 32 are snapped onto the upper end of the main ceiling keel 1. The main ceiling keel 1 is installed with the adjusting screw 4 via the hanger 41. The secondary ceiling keel 2 is then vertically attached to the lower end of the main ceiling keel 1. The positioning sliders 3 and limiting sliders 32 are moved so that the L-shaped hangers 6 and 61 at the lower end of the positioning sliders 3 and limiting sliders 32 are supported on the lower side of the secondary ceiling keel 2. The positioning sliders 3 and limiting sliders 32 are then screwed together with fastening nuts 33 to fix the spacing between them. This completes the installation of the ceiling keel.

[0021] In this embodiment, limiting protrusions 11 are provided on the upper edges of the inner walls of both the main ceiling joist 1 and the secondary ceiling joist 2. The main ceiling joist 1 is vertically distributed at the upper end of the secondary ceiling joist 2. The positioning slider 3 and the limiting slider 32 are engaged in an "I" shape at the limiting protrusions 11 of the main ceiling joist 1 and the secondary ceiling joist 2. The positioning slider 3 has a fixing stud 31 welded to its side, and the fixing stud 31 is fixed to the limiting slider 32 by a fastening nut 33. L-shaped hangers 6 and 61 are symmetrically supported at the outer end face of the secondary ceiling joist 2; and the sides of the L-shaped hangers 6 and 61 are attached to the main ceiling joist 1.

[0022] In a preferred embodiment, the fixing stud 31 and the fastening nut 33 fix the positions of the positioning slider 3 and the limiting slider 32, thereby positioning the spacing between the L-shaped hanger 1 5 and the L-shaped hanger 2 51, ensuring the stable vertical installation of the main ceiling joist 1 and the secondary ceiling joist 2. The wire rope 4 further secures the L-shaped hanger 1 6 and the L-shaped hanger 2 61, effectively preventing the connecting components of the ceiling joist from loosening or detaching from the joist surface, reducing the safety hazards caused by the detachment of the ceiling joist connection structure.

[0023] In this embodiment, a fixing block 51 is welded to the upper end of the lifting rod 5, and a limiting groove 43 is symmetrically opened on the threaded rod surface of the adjusting screw 4; and the limiting groove 43 is rectangular. The positioning stud 52 is symmetrically screwed to the left and right sides of the lifting rod 5 through the washer 54, and the adjusting screw 4 is threadedly sleeved on the inner side of the lifting rod 5.

[0024] In a preferred embodiment, the upper end of the hanger 5 is fixedly connected to the roof surface of the building via a fixing block 51, thereby enabling the hanger 5 to be suspended and installed. The limiting groove 43 on the threaded surface of the adjusting screw 4 corresponds to the anti-detachment insert 53, preventing the adjusting screw 4 from rotating due to external impact, thus activating the anti-detachment and anti-loosening function. This facilitates maintaining the hoisting height of the keel structure formed by the hanger 5 and the adjusting screw 4 after leveling, preventing the ceiling keel from tilting due to loose connection between the hanger 5 and the adjusting screw 4, ensuring the stability of the ceiling keel connection structure, and improving the hoisting effect of the ceiling keel connection structure.

[0025] This utility model of a building decorative ceiling keel connection structure effectively solves the problem in the prior art where the length of the adjusting screw and threaded sleeve connection between the keel and the hanger is easily changed by external impact, causing the connected ceiling keel to tilt and affecting the ceiling effect. It facilitates the restriction of loosening and displacement of the ceiling keel's hanging structure caused by external impact, makes it easier for the ceiling keel connection structure to maintain the leveled hanging height, ensures the stability of the ceiling keel connection structure, and improves the hanging effect of the ceiling keel connection structure. It is applicable to building decorative ceiling keel connection structures.
