Description

Technical Field

[0001] This utility model relates to the field of decoration technology, and in particular to a ceiling anti-cracking structure. Background Technology

[0002] Currently, ceiling joints, especially L-shaped corners, are typically connected using two keels. However, due to potential height differences before and after installation—for example, after laying plasterboard and applying putty—the putty is prone to cracking due to vibration or thermal expansion and contraction. Similarly, when plywood is laid on the keel, the joints between the plywood panels are also prone to cracking. Utility Model Content

[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] A ceiling crack prevention structure, including

[0029] The keel support 1 includes a horizontal keel 11 and a vertical keel 12 connected to the ceiling, wherein the vertical keel 12 is perpendicular to the horizontal keel 11 and connected to it to form an inner corner.

[0030] The first clamping plate 5 is disposed on the inner side of the transverse keel 11;

[0031] The second clamping plate 6 is located inside the longitudinal keel 12 and abuts against the first clamping plate 5.

[0032] A connecting plate 7 is located on the outside of the corner formed by the first clamping plate 5 and the second clamping plate 6, and covers the first clamping plate 5 and the second clamping plate 6.

[0033] This invention provides a ceiling crack-prevention structure. By covering the connection between the first and second clamping plates with a connector, the strength of the connection is enhanced, thereby preventing cracking after applying putty. It is particularly suitable for decorative ceilings.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the end of the first clamping plate 5 abuts against the inner side of the longitudinal keel 12, and the end of the second clamping plate 5 abuts against the first clamping plate 5. This increases the strength of the connection.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the connecting plate 7 is a galvanized steel plate, and the connecting plate 7 is provided with connecting holes 71 for screws to pass through and connect with the first clamping plate 5 or the second clamping plate 6. The thickness of the galvanized steel plate is 1.5mm.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the upper end of the connecting plate 7 is lower than the upper end of the first clamping plate 5 or the second clamping plate 6; the lower end of the connecting plate 7 is higher than the lower end of the first clamping plate 5 or the second clamping plate 6. This avoids the upper and lower ends of the connecting plate pressing against other positions, which could cause the positions of the first clamping plate and the second clamping plate to shift.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a hook-and-mount component 8, which is L-shaped, with one end connected to the outer side of the first clamping plate 5 or the second clamping plate 6, and the other end hooked onto the transverse keel 11 and the longitudinal keel 12 respectively. The hook-and-mount component is connected to the first clamping plate or the second clamping plate by screws.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a crack-resistant plate 2, which is disposed at the connection between the transverse keel 11 and the longitudinal keel 12 and is connected to the transverse keel 11 and the longitudinal keel 12.

[0039] The anti-crack plate 2 includes a main plate 21 that covers the bottom surfaces of both the transverse keel 11 and the longitudinal keel 12, and a first side plate 22 and a second side plate 23 that cover the opposing inner surfaces of the transverse keel 11 and the longitudinal keel 12, respectively. The main plate 21 has a main rivet hole 211, and the first side plate 22 and the second side plate 23 have side rivet holes 212. By using the anti-crack plate to cover the connection between the transverse and longitudinal keels, and using the main plate to cover the height difference between them, and applying putty to the main plate, cracking can be effectively prevented. At the same time, the first and second side plates increase the firmness of the main plate installation and prevent loosening.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the keel support 1 also includes a first keel 13 and a second keel 14 respectively disposed on two adjacent walls 3. The second keel 14 connects the first keel 13 to the outer surfaces of the transverse keel 11 and the longitudinal keel 12, respectively, and the main board 21 covers the second keel 14. This increases the keel support's stability while preventing cracking between the second keel and the transverse and longitudinal keels.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the first keel 13 forms an outer corner 4 at the corner of the wall, and the keel support 1 further includes a third keel 15 connected to the inner corner and the outer corner, with the main board 21 covering the third keel 15. This increases the keel support's stability while preventing cracking between the third keel and the horizontal and vertical keels.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the keel support 1 further includes a fourth keel 16 connected to the horizontal keel 11 or the vertical keel 12 and spaced apart from the wall, with the main board 21 covering the fourth keel 16. This increases the keel support's stability while preventing cracking between the fourth keel and the horizontal and vertical keels. The fourth keel is typically used to support the air outlet of a central air conditioning unit.

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the anti-crack plate 2 also includes a limiting plate 24 disposed on the main plate 21 and closely attached to the side of the second keel 14 to prevent displacement.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation, a V-shaped notch 25 is provided between the first side plate 22 and the second side plate 23. The first and second side plates are integrally connected to the main board. The notch facilitates bending of the first and second side plates while avoiding gaps at the connection points of the transverse and longitudinal keels.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the anti-crack plate 2 further includes an extension 26, which extends from the inner corner toward the transverse keel 11 and the longitudinal keel 12 to protrude from the main plate 21;

[0046] The first side plate 22 and the second side plate 23 extend synchronously with the extension portion 26, thereby strengthening the mainboard.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, the motherboard 21 is provided with a horizontally extending transverse groove 27 and a vertically extending longitudinal groove 28. The transverse groove 27 and the longitudinal groove 28 are respectively connected to the second keel 14 by pull studs, and the extension direction of the second keel 14 is perpendicular to the extension direction of the transverse groove 27 or the longitudinal groove 28. The motherboard is fixed and limited from both the transverse and longitudinal directions.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation, the motherboard 21 is provided with a corner groove 29, which is connected to the third keel 15 by a pull stud, and the extension direction of the corner groove 29 is perpendicular to the extension direction of the third keel 15.

[0049] Furthermore, as a preferred embodiment of this solution and not a limitation, the motherboard 21 is also provided with a connecting groove 20, which is connected to the fourth keel 16 by a pull stud, and the extending direction of the connecting groove 20 is perpendicular to the extending direction of the fourth keel 16.

[0050] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
