[0002] Currently, suspended ceilings are typically constructed by attaching decorative panels to a frame. Decorative panels, as an excellent ceiling / partition wall substrate, offer excellent fire resistance, moisture resistance, stability, and durability. They replace plywood and gypsum board and are widely used in residential, hotel, hospital, office, and large public buildings, becoming a crucial building material for interior decoration. However, the decorative panels of conventional suspended ceilings often crack after installation, resulting in a poor customer experience and hindering their wider application and promotion.

[0003] The main reasons for cracking include the following:

[0004] 1. The inherent characteristics of the board, shrinkage and expansion when wet: shrinkage and expansion when wet are the natural characteristics of ordinary decorative boards. As a decorative material, this property is one of its weaknesses. Improper selection and handling will affect the application results.

[0005] 2. Improper skeleton matching leads to: the rigid connection is too weak, the difference between the expansion and contraction of the skeleton and the plate leads to cracking; the skeleton strength is insufficient, deformation, falling and leading to cracking.

[0006] How to design a crack-resistant suspended ceiling has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] The purpose of the utility model is to solve the deficiencies of the prior art and provide a crack-resistant and impact-resistant suspended ceiling.

[0008] The technical solution adopted by the utility model is: a crack-resistant and impact-resistant suspended ceiling, comprising:

[0009] A keel frame, comprising a plurality of transverse keels and longitudinal keels, wherein the transverse keels and longitudinal keels are crisscrossed;

[0010] A suspension assembly, comprising a plurality of detachable suspension rods and suspension lines arranged above the keel frame; the suspension rods are parallel to the longitudinal keels and are arranged alternately with the longitudinal keels; the suspension rods are connected to the transverse keels via a plurality of keel clips, and the suspension lines are connected to the suspension rods via suspension connectors; and,

[0012] Preferably, the transverse keel is a U-shaped steel channel, and the tops of both side edges of the transverse keel are rolled inward to form a clamping portion for clamping the keel clamp.

[0013] Preferably, the keel clamp includes two hook pieces located on both sides of the transverse keel, and both ends of the bottom of the hook piece extend outward to form supporting protrusions for clamping the transverse keel clamping part.

[0014] Preferably, the suspension connector includes a U-shaped hook for hooking the suspension rod and a fixing rod detachably arranged at the hook mouth of the U-shaped hook, and one side of the U-shaped hook extends upward to have a connecting portion connected to the free end of the suspension line.

[0015] Preferably, the fixing rod is a screw rod, and the U-shaped hook is provided with a through hole for the screw rod to pass through.

[0016] Preferably, the connecting portion is provided with a suspension hole for the suspension wire to pass through, and the suspension wire is connected to the connecting portion via a nut.

[0017] Preferably, the longitudinal keel includes a plurality of longitudinal steel grooves arranged between two adjacent transverse keels.

[0018] Preferably, the keel frame and suspension components are both made of stainless steel.

[0021] Preferably, the apparent density of the anti-cracking decorative board is 0.9±0.05 g / cm 3 .

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. The crack-resistant and impact-resistant ceiling of this utility model utilizes suspension rods, which are interspersed with longitudinal keels, to securely connect the keel frame. Suspension wires are then connected to the suspension rods, thereby suspending the entire keel frame from the ceiling. The interspersed arrangement of the suspension rods and longitudinal keels enhances the strength and rigidity of the entire keel frame. When any one of the transverse and longitudinal keels in the keel frame deforms horizontally, the other keels remain stationary, thus preventing the crack-resistant decorative panels from being pulled and cracked by the simultaneous deformation of the transverse and longitudinal keels.

[0024] 2. The anti-cracking and impact-resistant ceiling of the present invention uses anti-cracking decorative panels as the decorative surface. The anti-cracking decorative panels are made of a mixture of various silicon and calcium materials and have better flexibility to resist the deformation of the keel frame, further reducing the risk of cracking of the anti-cracking decorative panels. In addition, the apparent density (g / cm 3) is 0.9±0.05, it is light in weight, there is no need to consider the additional load on the ceiling or wall, it can be divided and laid out at will, which is beneficial to reducing the dead weight of the building and has good seismic performance.

[0025] 3. The crack-resistant and impact-resistant suspended ceiling of the present invention has a suspension rod connected to the transverse keel through a number of keel clips, and a suspension line connected to the suspension rod through a suspension connector, so that the entire keel frame has a certain amount of space for movement in the longitudinal direction, which can buffer the impact of the longitudinal impact force on the keel frame, thereby improving the impact resistance of the suspended ceiling.

DETAILED DESCRIPTION

[0031] To deepen the understanding of the present invention, the present invention will be further described below in conjunction with implementation examples and accompanying drawings. The present invention can be implemented in the following ways:

[0032] Reference Figure 1-3 A crack-resistant and impact-resistant ceiling includes a keel frame 1, a suspension component 2 and an anti-cracking decorative panel 3. The keel frame 1 and the suspension component 2 are both made of stainless steel, which can prevent rust from reducing the service life of the keel frame 1.

[0033] The keel frame 1 includes a plurality of transverse keels 11 and longitudinal keels 12. The transverse keels 11 and longitudinal keels 12 are crisscrossed. In this embodiment, the transverse keels 11 and longitudinal keels 12 are arranged perpendicularly. The longitudinal keels 12 include a plurality of longitudinal steel grooves arranged between two adjacent transverse keels 11.

[0034] The suspension assembly 2 includes a number of detachable suspension rods 21 and suspension lines 22 arranged above the keel frame 1; the suspension rods 21 are parallel to the longitudinal keels 12 and are distributed alternately with the longitudinal keels 12; this design can improve the strength and rigid connection of the entire keel frame 1. When any transverse keel 11 and longitudinal keel 12 in the keel frame 1 are deformed in the horizontal direction, the other keels do not move with it, thereby preventing the anti-cracking decorative panel 3 from being cracked by the simultaneous deformation and pulling of the transverse keels 11 and the longitudinal keels 12.

[0035] The suspension rod 21 is connected to the transverse keel 11 via a number of keel clips 23. In this embodiment, the suspension rod 21 is connected to the transverse keel 11 at each point where it intersects the keel clip 23, further enhancing the rigidity of the keel frame 1. Specifically, the transverse keel 11 is a U-shaped steel channel, and the tops of both sides of the transverse keel 11 are rolled inward to form a clamping portion 111 for clamping the keel clip 23. The keel clip 23 includes two hook pieces 231 located on both sides of the transverse keel 11. The bottom ends of the hook pieces 231 extend outward to form support protrusions 232 for clamping the clamping portion 111 of the transverse keel 11. During installation, first place the bottom of the keel clip 23 into the U-shaped steel groove of the transverse keel 11, so that the top of the supporting protrusions 232 at both ends of the keel clip 23 abuts against the clamping part 111 of the transverse keel 11, and then hang the hook piece 231 of the keel clip 23 on the suspension rod 21. The operation is simple and quick.

[0036] The suspension wire 22 is connected to the suspension rod 21 via a suspension connector 24; the suspension wire 22 is a steel wire. The suspension connector 24 comprises a U-shaped hook 241 for hooking onto the suspension rod 21 and a removable fixing rod 242 at the hook opening of the U-shaped hook 241. The fixing rod 242 is a screw, and the U-shaped hook 241 is provided with a through hole for the screw to pass through. Extending upward from one side of the U-shaped hook 241 is a connecting portion 243 that connects to the free end of the suspension wire 22. The connecting portion 243 is provided with a suspension hole for the suspension wire 22 to pass through. The suspension wire 22 is connected to the connecting portion 243 via a nut. During installation, the U-shaped hook 241 of the suspension connector 24 is hooked onto the suspension rod 21, the screw is passed through the through hole, and both ends are secured with nuts. The suspension wire 22 is then passed through the suspension hole and secured to the connecting portion 243 with a nut. This is simple and quick. The design of the keel clips 23 and the suspension connectors 24 allows the entire keel frame to have a certain amount of space for movement in the longitudinal direction, which can buffer the impact of the longitudinal impact force on the keel frame, thereby improving the impact resistance of the suspended ceiling.

[0037] The anti-cracking decorative panel 3 is detachably arranged under the keel frame 1. The anti-cracking decorative panel 3 includes a base plate 31 and a panel 32, and the base plate 31 faces the keel frame 1. The base plate 31 can be fixed to the keel with self-tapping screws. The anti-cracking decorative panel 3 of this embodiment adopts a mixture of various siliceous and calcareous materials, and has a balanced and tight crystal structure synthesized by a special high-temperature and high-pressure reaction, and has extremely stable performance. The chipping of the board can be reduced during the installation process. In addition, the crystal structure is tight and balanced, and after multiple kneading and loosening after deacidification, the fibers form a forked trunk shape, which makes the board more flexible and further improves the anti-cracking ability of the ceiling.

[0038] In addition, the apparent density (g / cm 3 This design makes the anti-cracking decorative panel 3 light in weight, without considering the additional load on the ceiling or wall, and can be divided and arranged at will, which is beneficial to reducing the deadweight of the building and has good earthquake resistance.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
